Food security

Food security is a measure of the availability of food and individuals' ability to access it. Affordability is only one factor. There is evidence of food security being a concern many thousands of years ago, with central authorities in ancient China and ancient Egypt being known to release food from storage in times of famine. At the 1974 World Food Conference the term "food security" was defined with an emphasis on supply. They said food security is the "availability at all times of adequate, nourishing, diverse, balanced and moderate world food supplies of basic foodstuffs to sustain a steady expansion of food consumption and to offset fluctuations in production and prices".^[1] Later definitions added demand and access issues to the definition. The final report of the 1996 World Food Summit states that food security "exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life."^[2][3]

Household food security exists when all members, at all times, have access to enough food for an active, healthy life.^[4] Individuals who are food secure do not live in hunger or fear of starvation.^[5] Food insecurity, on the other hand, is defined by the United States Department of Agriculture (USDA) as a situation of "limited or uncertain availability of nutritionally adequate and safe foods or limited or uncertain ability to acquire acceptable foods in socially acceptable ways".^[6] Food security incorporates a measure of resilience to future disruption or unavailability of critical food supply due to various risk factors including droughts, shipping disruptions, fuel shortages, economic instability, and wars. In the years 2011–2013, an estimated 842 million people were suffering from chronic hunger.^[7] The Food and Agriculture Organization of the United Nations, or FAO, identified the four pillars of food security as availability, access, utilization, and stability.^[8] The United Nations (UN) recognized the Right to Food in the Declaration of Human Rights in 1948,^[5] and has since said that it is vital for the enjoyment of all other rights.^[9]

The 1996 World Summit on Food Security declared that "food should not be used as an instrument for political and economic pressure".^[3]

Measurement

Food security can be measured by calorie to intake per person per day, available on a household budget.^[10][11] In general, the objective of food security indicators and measurements is to capture some or all of the main components of food security in terms of food availability, accessibility, and utilization/adequacy. While availability (production and supply) and utilization/adequacy (nutritional status/anthropometric measurement) are easier to estimate and, therefore, more popular, accessibility (the ability to acquire the sufficient quantity and quality of food) remains largely elusive.^[12] The factors influencing household food accessibility are often context-specific.^[13]

Several measurements have been developed to capture the access component of food security, with some notable examples developed by the USAID-funded Food and Nutrition Technical Assistance (FANTA) project, collaborating with Cornell and Tufts University and Africare and World Vision.^{[13][14][15][16]} These include:

• Household Food Insecurity Access Scale (HFIAS) – continuously measures the degree of food insecurity (inaccessibility) in the household in the previous month
• Household Dietary Diversity Scale (HDDS) – measures the number of different food groups consumed over a specific reference period (24hrs/48hrs/7days).
• Household Hunger Scale (HHS)- measures the experience of household food deprivation based on a set of predictable reactions, captured through a survey and summarized in a scale.
• Coping Strategies Index (CSI) – assesses household behaviors and rates them based on a set of varied established behaviors on how households cope with food shortages. The methodology for this research is based on collecting data on a single question: "What do you do when you do not have enough food, and do not have enough money to buy food?"^[17][18][19]

Food insecurity is measured in the United States by questions in the Census Bureau's Current Population Survey. The questions asked are about anxiety that the household budget is inadequate to buy enough food, inadequacy in the quantity or quality of food eaten by adults and children in the household, and instances of reduced food intake or consequences of reduced food intake for adults and for children.^[20] A National Academy of Sciences study commissioned by the USDA criticized this measurement and the relationship of "food security" to hunger, adding "it is not clear whether hunger is appropriately identified as the extreme end of the food security scale."^[21]

The FAO, World Food Programme (WFP), and International Fund for Agricultural Development (IFAD) collaborate to produce The State of Food Insecurity in the World. The 2012 edition described improvements made by the FAO to the prevalence of undernourishment (PoU) indicator that is used to measure rates of food insecurity. New features include revised minimum dietary energy requirements for individual countries, updates to the world population data, and estimates of food losses in retail distribution for each country. Measurements that factor into the indicator include dietary energy supply, food production, food prices, food expenditures, and volatility of the food system.^[22] The stages of food insecurity range from food secure situations to full-scale famine.^[23] A new peer-reviewed journal, Food Security: The Science, Sociology and Economics of Food Production and Access to Food, began publishing in 2009.^[24]

Rates

Number of people affected by undernourishment in 2010–12 (by region, in millions)^[25]

With its prevalence of undernourishment (PoU) indicator, the FAO reported that almost 870 million people were chronically undernourished in the years 2010–2012. This represents 12.5% of the global population, or 1 in 8 people. The 2018 prevalence of food insecurity declined, for the first time, to the pre-recession(2007) level of 11.1 percent.^[26] Higher rates occur in developing countries, where 852 million people (about 15% of the population) are chronically undernourished. The report noted that Asia and Latin America have achieved reductions in rates of undernourishment that put these regions on track for achieving the Millennium Development Goal of halving the prevalence of undernourishment by 2015.^[22] The UN noted that about 2 billion people do not consume a sufficient amount of vitamins and minerals.^[27] In India, the second-most populous country in the world, 30 million people have been added to the ranks of the hungry since the mid-1990s and 46% of children are underweight.^[28]

Examples of food insecurity

Famines have been frequent in world history. Some have killed millions and substantially diminished the population of a large area. The most common causes have been drought and war, but the greatest famines in history were caused by economic policy.

Afghanistan

In Afghanistan, about 35% of households are food insecure. The prevalence of under-weight, stunting, and wasting in children under 5 years of age is also very high.^[29]

China

The persistence of wet markets has been described as "critical for ensuring urban food security",^[30][31] particularly in Chinese cities.^[32] The influence of wet markets on urban food security include food pricing and physical accessibility.^[32]

Mexico

Food insecurity has been an issue for Mexico throughout its history. Although food availability is not the issue, severe deficiencies in the accessibility of food contributes to the insecurity. Between 2003 and 2005, the total Mexican food supply was well above the sufficient to meet the requirements of the Mexican population, averaging 3,270 kilocalories per daily capita, higher than the minimum requirements of 1,850 kilocalories per daily capita. However, at least 10 percent of the population in every Mexican state suffers from inadequate food access. In nine states, 25–35 percent live in food-insecure households. More than 10 percent of the populations of seven Mexican states fall into the category of Serious Food Insecurity.^[33]

The issue of food inaccessibility is magnified by chronic child malnutrition, as well as obesity in children, adolescents, and family.^[34]

Mexico is vulnerable to drought, which can further cripple agriculture.^[35]

Singapore

In 2019, Singapore managed to produce only 13% of leafy vegetables, 24% of its eggs, and 9% of its fish. In 1965, it was still able to produce 60% of its vegetable demand, 80% of its poultry and 100% of its eggs. In 2019, it announced it launched the "30 by 30" program which aims to drastically reduce its food insecurity through hydroponic farms and aquaculture farms.^[36][37]

United States

Infographic about food insecurity in the US

The Agriculture Department defines food insecurity as "limited or uncertain availability of nutritionally adequate and safe foods or limited or uncertain ability to acquire acceptable foods in socially acceptable ways."^[38] Food security is defined by the USDA as "access by all people at all times to enough food for an active, healthy life."^[39]

National Food Security Surveys are the main survey tool used by the USDA to measure food security in the United States. Based on respondents' answers to survey questions, the household can be placed on a continuum of food security defined by the USDA. This continuum has four categories: high food security, marginal food security, low food security, and very low food security.^[38] The continuum of food security ranges from households that consistently have access to nutritious food to households where at least one or more members routinely go without food due to economic reasons.^[40] Economic Research Service report number 155 (ERS-155) estimates that 14.5 percent (17.6 million) of US households were food insecure at some point in 2012.

Across 2016, 2017 and 2018:^[41][42][43]

• 11.1 percent (14.3 million) of U.S. households were food insecure at some time during 2018.
• In 6.8 percent of households with children, only adults were food insecure in 2018.
• Both children and adults were food insecure in 7.1 percent of households with children (2.7 million households) in 2018.
• 11.8 percent (15.0 million) of U.S. households were food insecure at some time during 2017.
• 7.4 percent (9.4 million) of U.S. households had low food security in 2016.
• 4.9 percent (6.1 million) of U.S. households had very low food security at some time during 2016.
• Both children and adults were food insecure in 8.0 percent of households with children (3.1 million households).

Democratic Republic of Congo

The Democratic Republic of Congo is the second-largest country in Africa and is dealing with food insecurity. Although they have an abundance of natural resources, they lack accessibility of essential foods, which makes it difficult for the Congolese people in their daily lives. Malnutrition is high among children, which affects their ability, and children who live in a rural area are affected more than children who live in an urban area.^[44] In the Democratic Republic of Congo, about 33% of households are food insecure; it is 60% in eastern provinces.^[45] A study showed the correlation of food insecurity negatively affecting at-risk HIV adults in the Democratic Republic of Congo.^[45]

In 2007–2008, grain prices increased and the people in the Democratic Republic of the Congo went to civil unrest. There were riots and protests. Hunger is frequent in the country, but sometimes it is to the extreme that many families cannot afford to eat every day.^[46] Bushmeat trade was used to measure the trend of food security. The trend signifies the amount of consumption in urban and rural areas. Urban areas mainly consume bushmeat because they cannot afford other types of meat.^[47]

Feed the Future

In 2010, the government of the United States began the Feed the Future Initiative.^[48] The initiative is expected to work on the basis of country-led priorities that call for consistent support by the governments, donor organizations, the private sector, and the civil society to accomplish its long-term goals.^[48]

World Summit on Food Security

The World Summit on Food Security, held in Rome in 1996, aimed to renew a global commitment to the fight against hunger. The Food and Agriculture Organization of the United Nations (FAO) called the summit in response to widespread under-nutrition and growing concern about the capacity of agriculture to meet future food needs. The conference produced two key documents, the Rome Declaration on World Food Security and the World Food Summit Plan of Action.^[3][49]

The Rome Declaration called for the members of the United Nations to work to halve the number of chronically undernourished people on the Earth by the year 2015. The Plan of Action set a number of targets for government and non-governmental organizations for achieving food security, at the individual, household, national, regional and global levels.

Another World Summit on Food Security took place at the FAO's headquarters in Rome between November 16 and 18, 2009.^[50] The decision to convene the summit was taken by the Council of FAO in June 2009, at the proposal of FAO Director-General Dr Jacques Diouf. Heads of state and government attended this summit.

Pillars of food security

Growth in food production has been greater than population growth. Food per person increased since 1961. Data source: Food and Agriculture Organization.

Growth of World Food Supply (caloric base) per capita

The WHO states that there are three pillars that determine food security: food availability, food access, and food use and misuse.^[51] The FAO adds a fourth pillar: the stability of the first three dimensions of food security over time.^[5] In 2009, the World Summit on Food Security stated that the "four pillars of food security are availability, access, utilization, and stability".^[8]

Availability

Food availability relates to the supply of food through production, distribution, and exchange.^[52] Food production is determined by a variety of factors including land ownership and use; soil management; crop selection, breeding, and management; livestock breeding and management; and harvesting.^[53] Crop production can be affected by changes in rainfall and temperatures.^[52] The use of land, water, and energy to grow food often competes with other uses, which can affect food production.^[54] Land used for agriculture can be used for urbanization or lost to desertification, salinization, and soil erosion due to unsustainable agricultural practices.^[54] Crop production is not required for a country to achieve food security. Nations don't have to have the natural resources required to produce crops in order to achieve food security, as seen in the examples of Japan^[55][56] and Singapore.^[57]

Because food consumers outnumber producers in every country,^[57] food must be distributed to different regions or nations. Food distribution involves the storage, processing, transport, packaging, and marketing of food.^[53] Food-chain infrastructure and storage technologies on farms can also affect the amount of food wasted in the distribution process.^[54] Poor transport infrastructure can increase the price of supplying water and fertilizer as well as the price of moving food to national and global markets.^[54] Around the world, few individuals or households are continuously self-reliant for food. This creates the need for a bartering, exchange, or cash economy to acquire food.^[52] The exchange of food requires efficient trading systems and market institutions, which can affect food security.^[58] Per capita world food supplies are more than adequate to provide food security to all, and thus food accessibility is a greater barrier to achieving food security.^[57]

Access

Goats are an important part of the solution to global food security because they are fairly low-maintenance and easy to raise and farm.

Food access refers to the affordability and allocation of food, as well as the preferences of individuals and households.^[52] The UN Committee on Economic, Social, and Cultural Rights noted that the causes of hunger and malnutrition are often not a scarcity of food but an inability to access available food, usually due to poverty.^[9] Poverty can limit access to food, and can also increase how vulnerable an individual or household is to food price spikes.^[58] Access depends on whether the household has enough income to purchase food at prevailing prices or has sufficient land and other resources to grow its own food.^[59] Households with enough resources can overcome unstable harvests and local food shortages and maintain their access to food.^[57]

There are two distinct types of access to food: direct access, in which a household produces food using human and material resources, and economic access, in which a household purchases food produced elsewhere.^[53] Location can affect access to food and which type of access a family will rely on.^[59] The assets of a household, including income, land, products of labor, inheritances, and gifts can determine a household's access to food.^[53] However, the ability to access sufficient food may not lead to the purchase of food over other materials and services.^[58] Demographics and education levels of members of the household as well as the gender of the household head determine the preferences of the household, which influences the type of food that are purchased.^[59] A household's access to enough and nutritious food may not assure adequate food intake of all household members, as intrahousehold food allocation may not sufficiently meet the requirements of each member of the household.^[58] The USDA adds that access to food must be available in socially acceptable ways, without, for example, resorting to emergency food supplies, scavenging, stealing, or other coping strategies.^[4]

Utilization

The next pillar of food security is food utilization, which refers to the metabolism of food by individuals.^[57] Once food is obtained by a household, a variety of factors affect the quantity and quality of food that reaches members of the household. In order to achieve food security, the food ingested must be safe and must be enough to meet the physiological requirements of each individual.^[58] Food safety affects food utilization,^[52] and can be affected by the preparation, processing, and cooking of food in the community and household.^[53] Nutritional values^[52] of the household determine food choice,^[53] and whether food meets cultural preferences is important to utilization in terms of psychological and social well-being.^[60] Access to healthcare is another determinant of food utilization, since the health of individuals controls how the food is metabolized.^[53] For example, intestinal parasites can take nutrients from the body and decrease food utilization.^[57] Sanitation can also decrease the occurrence and spread of diseases that can affect food utilization.^[53][61] Education about nutrition and food preparation can affect food utilization and improve this pillar of food security.^[57]

Stability

Food stability refers to the ability to obtain food over time. Food insecurity can be transitory, seasonal, or chronic.^[53] In transitory food insecurity, food may be unavailable during certain periods of time.^[58] At the food production level, natural disasters^[58] and drought^[53] result in crop failure and decreased food availability. Civil conflicts can also decrease access to food.^[58] Instability in markets resulting in food-price spikes can cause transitory food insecurity. Other factors that can temporarily cause food insecurity are loss of employment or productivity, which can be caused by illness. Seasonal food insecurity can result from the regular pattern of growing seasons in food production.^[53]

Chronic (or permanent) food insecurity is defined as the long-term, persistent lack of adequate food.^[58] In this case, households are constantly at risk of being unable to acquire food to meet the needs of all members. Chronic and transitory food insecurity are linked, since the reoccurrence of transitory food security can make households more vulnerable to chronic food insecurity.^[53]

Effects of food insecurity

Famine and hunger are both rooted in food insecurity. Chronic food insecurity translates into a high degree of vulnerability to famine and hunger; ensuring food security presupposes elimination of that vulnerability.^[23]

Stunting and chronic nutritional deficiencies

Many countries experience ongoing food shortages and distribution problems. These result in chronic and often widespread hunger amongst significant numbers of people. Human populations can respond to chronic hunger and malnutrition by decreasing body size, known in medical terms as stunting or stunted growth.^[62] This process starts in utero if the mother is malnourished and continues through approximately the third year of life. It leads to higher infant and child mortality, but at rates far lower than during famines.^[63] Once stunting has occurred, improved nutritional intake after the age of about two years is unable to reverse the damage. Stunting itself can be viewed as a coping mechanism, bringing body size into alignment with the calories available during adulthood in the location where the child is born.^[63] Limiting body size as a way of adapting to low levels of energy (calories) adversely affects health in three ways:^[63]

• Premature failure of vital organs during adulthood. For example, a 50-year-old individual might die of heart failure because his/her heart suffered structural defects during early development;
• Stunted individuals suffer a higher rate of disease and illness than those who have not undergone stunting;
• Severe malnutrition in early childhood often leads to defects in cognitive development.^[64] It therefore creates disparity among children who did not experience severe malnutrition and those who experience it.

Depression, anxiety, and sleep disorders

A recent comprehensive systematic review showed that over 50 studies have shown that food insecurity is strongly associated with a higher risk of depression, anxiety, and sleep disorders.^[65] For depression and anxiety, food-insecure individuals have almost a threefold risk increase compared to food-secure individuals.

Challenges to achieving food security

Global water crisis

Irrigation canals have opened dry desert areas of Egypt to agriculture.

Water deficits, which are already spurring heavy grain imports in numerous smaller countries,^[66] may soon do the same in larger countries, such as China or India.^[67] The water tables are falling in scores of countries (including northern China, the US, and India) due to widespread overpumping using powerful diesel and electric pumps. Other countries affected include Pakistan, Afghanistan, and Iran. This will eventually lead to water scarcity and cutbacks in grain harvest. Even with the overpumping of its aquifers, China is developing a grain deficit.^[68] When this happens, it will almost certainly drive grain prices upward. Most of the 3 billion people projected to be born worldwide by mid-century will be born in countries already experiencing water shortages. After China and India, there is a second tier of smaller countries with large water deficits – Afghanistan, Algeria, Egypt, Iran, Mexico, and Pakistan. Four of these already import a large share of their grain. Only Pakistan remains self-sufficient. But with a population expanding by 4 million a year, it will likely soon turn to the world market for grain.^[69]

Regionally, Sub-Saharan Africa has the largest number of water-stressed countries of any place on the globe, as of an estimated 800 million people who live in Africa, 300 million live in a water-stressed environment.^[70] It is estimated that by 2030, 75 million to 250 million people in Africa will be living in areas of high water stress, which will likely displace anywhere between 24 million and 700 million people as conditions become increasingly unlivable.^[70] Because the majority of Africa remains dependent on an agricultural lifestyle and 80 to 90 percent of all families in rural Africa rely upon producing their own food,^[71] water scarcity translates to a loss of food security.

Multimillion-dollar investments beginning in the 1990s by the World Bank have reclaimed desert and turned the Ica Valley in Peru, one of the driest places on earth, into the largest supplier of asparagus in the world. However, the constant irrigation has caused a rapid drop in the water table, in some places as much as eight meters per year, one of the fastest rates of aquifer depletion in the world. The wells of small farmers and local people are beginning to run dry and the water supply for the main city in the valley is under threat. As a cash crop, asparagus has provided jobs for local people, but most of the money goes to the buyers, mainly the British. A 2010 report concluded that the industry is not sustainable and accuses investors, including the World Bank, of failing to take proper responsibility for the effect of their decisions on the water resources of poorer countries.^[72] Diverting water from the headwaters of the Ica River to asparagus fields has also led to a water shortage in the mountain region of Huancavelica, where indigenous communities make a marginal living herding.^[73]

Land degradation

Intensive farming often leads to a vicious cycle of exhaustion of soil fertility and decline of agricultural yields.^[74] Approximately 40 percent of the world's agricultural land is seriously degraded.^[75] According to UNU's Ghana-based Institute for Natural Resources in Africa,^[76] if current trends of soil degradation continue, Africa might be able to feed just 25 percent of its population by 2025.

Climate change

Extreme events, such as droughts and floods, are forecast to increase as climate change and global warming takes hold.^[77] Ranging from overnight floods to gradually worsening droughts, these will have a range of effects on the agricultural sector as well as the species that various communities are able to grow.^[78] According to the Climate & Development Knowledge Network report Managing Climate Extremes and Disasters in the Agriculture Sectors: Lessons from the IPCC SREX Report, the effects will include changing productivity and livelihood patterns, economic losses, and effects on infrastructure, markets and food security. Food security in future will be linked to our ability to adapt agricultural systems to extreme events. An example of a shifting weather pattern would be a rise in temperatures. As temperatures rise due to climate change there is a risk of a diminished food supply due to heat damage.^[79]

Approximately 2.4 billion people live in the drainage basin of the Himalayan rivers.^[80] India, China, Pakistan, Afghanistan, Bangladesh, Nepal and Myanmar could experience floods followed by severe droughts in coming decades.^[81] In India alone, the Ganges provides water for drinking and farming for more than 500 million people.^[82][83] The west coast of North America, which gets much of its water from glaciers in mountain ranges such as the Rocky Mountains and Sierra Nevada, also would be affected.^[84] Glaciers aren't the only worry that the developing nations have; sea level is reported to rise as climate change progresses, reducing the amount of land available for agriculture.^[85][86]

In other parts of the world, a big effect will be low yields of grain according to the World Food Trade Model, specifically in the low latitude regions where much of the developing world is located. From this the price of grain will rise, along with the developing nations trying to grow the grain. Due to this, every 2–2.5% price hike will increase the number of hungry people by 1%.^[85] Low crop yields are just one of the problem facing farmers in the low latitudes and tropical regions. The timing and length of the growing seasons, when farmers plant their crops, are going to be changing dramatically, per the USDA, due to unknown changes in soil temperature and moisture conditions.^[87]

Another way of thinking about food security and climate change comes from Evan Fraser, a geographer working at the University of Guelph in Ontario Canada . His approach is to explore the vulnerability of food systems to climate change and he defines vulnerability to climate change as situations that occur when relatively minor environmental problems cause major effects on food security. Examples of this include the Irish Potato Famine^{[88][dubious – discuss]}, which was caused by a rainy year that created ideal conditions for the fungal blight to spread in potato fields, or the Ethiopian Famine in the early 1980s.^[89] Three factors stand out as common in such cases, and these three factors act as a diagnostic "tool kit" through which to identify cases where food security may be vulnerable to climate change. These factors are: (1) specialized agro-ecosystems; (2) households with very few livelihood options other than farming; (3) situations where formal institutions do not provide adequate safety nets to protect people.^[89] "The International Food Policy Research Institute (IFPRI) estimates that an additional US$ 7.1–7.3 billion per year are needed in agricultural investments to offset the negative effect of climate change on nutrition for children by 2050 (Table 6)."^[90]

Agricultural diseases

Diseases affecting livestock or crops can have devastating effects on food availability especially if there are no contingency plans in place. For example, Ug99, a lineage of wheat stem rust, which can cause up to 100% crop losses, is present in wheat fields in several countries in Africa and the Middle East and is predicted to spread rapidly through these regions and possibly further afield, potentially causing a wheat production disaster that would affect food security worldwide.^[91][92]

The genetic diversity of the crop wild relatives of wheat can be used to improve modern varieties to be more resistant to rust. In their centers of origin wild wheat plants are screened for resistance to rust, then their genetic information is studied and finally wild plants and modern varieties are crossed through means of modern plant breeding in order to transfer the resistance genes from the wild plants to the modern varieties.^[93][94]

Food versus fuel

Farmland and other agricultural resources have long been used to produce non-food crops including industrial materials such as cotton, flax, and rubber; drug crops such as tobacco and opium, and biofuels such as firewood, etc. In the 21st century the production of fuel crops has increased, adding to this diversion. However technologies are also developed to commercially produce food from energy such as natural gas and electrical energy with tiny water and land foot print.^{[95][96][97][98]}

Politics

Nobel Prize winning economist Amartya Sen observed that "there is no such thing as an apolitical food problem."^[99] While drought and other naturally occurring events may trigger famine conditions, it is government action or inaction that determines its severity, and often even whether or not a famine will occur. The 20th century has examples of governments, as in Collectivization in the Soviet Union or the Great Leap Forward in the People's Republic of China undermining the food security of their own nations. Mass starvation is frequently a weapon of war, as in the blockade of Germany, the Battle of the Atlantic, and the blockade of Japan during World War I and World War II and in the Hunger Plan enacted by Nazi Germany.

Governments sometimes have a narrow base of support, built upon cronyism and patronage. Fred Cuny pointed out in 1999 that under these conditions: "The distribution of food within a country is a political issue. Governments in most countries give priority to urban areas, since that is where the most influential and powerful families and enterprises are usually located. The government often neglects subsistence farmers and rural areas in general. The more remote and underdeveloped the area the less likely the government will be to effectively meet its needs. Many agrarian policies, especially the pricing of agricultural commodities, discriminate against rural areas. Governments often keep prices of basic grains at such artificially low levels that subsistence producers cannot accumulate enough capital to make investments to improve their production. Thus, they are effectively prevented from getting out of their precarious situation."^[100]

Socialist governments have used food as a political weapon, rewarding supporters while denying food supplies to areas that oppose their rule.^[101] Under such conditions food becomes a currency with which to buy support and famine becomes an effective weapon against opposition.^{[102][original research?]}

A government with a strong tendency towards kleptocracy can undermine food security even when harvests are good. When the rule of law is absent, or private property is non-existent, farmers have little incentive to improve their productivity.^{[according to whom?]} If a farm becomes noticeably more productive than neighboring farms, it may become the target of individuals well connected to the government. Rather than risk being noticed and possibly losing their land, farmers may be content with the perceived safety of mediocrity.^[103]

Food sovereignty

The approach known as food sovereignty views the business practices of multinational corporations as a form of neocolonialism. It contends that multinational corporations have the financial resources available to buy up the agricultural resources of impoverished nations, particularly in the tropics. They also have the political clout to convert these resources to the exclusive production of cash crops for sale to industrialized nations outside of the tropics, and in the process to squeeze the poor off of the more productive lands.^[73] Under this view, subsistence farmers are left to cultivate only lands that are so marginal in terms of productivity as to be of no interest to the multinational corporations. Likewise, food sovereignty holds it to be true that communities should be able to define their own means of production and that food is a basic human right. With several multinational corporations now pushing agricultural technologies on developing countries, technologies that include improved seeds, chemical fertilizers, and pesticides, crop production has become an increasingly analyzed and debated issue.

Food waste

Food waste may be diverted for alternative human consumption when economic variables allow for it. The waste of consumable food is even gaining attention from large food conglomerates. For instance, due to low food prices, simply discarding irregular carrots has typically been more cost-effective than spending money on the extra labor or machinery necessary to handle them. A juice factory in the Netherlands, however, has developed a process to efficiently divert and use previously rejected carrots, and its parent company is expanding this innovation to plants in Great Britain.^[104]

In recent years, France has worked to combat food insecurity, in part by addressing food waste; since 2013 the country has passed laws prohibiting grocery stores from discarding unsold food items, requiring that they instead donate the food to designated charities.^[105] Nevertheless, according to the Economist's Global Food Security Index, overall food insecurity remains more severe in France than the United States despite higher nation-wide estimates of food waste in the U.S.^[105]

Local efforts, such as the Greater Franklin Food Council in Farmington, Maine, can directly help regional food security, particularly when residents become mindful of the juxtaposition of food insecurity in their communities with their own food waste at home. Learning that the average family of four throws away $1,500 worth of food per year while neighbors may be going hungry can provide the motivation to waste less and give more: waste less money at the grocery store and give more to the food pantry.^[106]

Risks to food security

Population growth

Current UN projections show a continued increase in population in the future (but a steady decline in the population growth rate), with the global population expected to reach 9.8 billion in 2050 and 11.2 billion by 2100.^[107] Estimates by the UN Population Division for the year 2150 range between 3.2 and 24.8 billion;^[108] mathematical modeling supports the lower estimate.^[109] Some analysts have questioned the sustainability of further world population growth, highlighting the growing pressures on the environment, global food supplies, and energy resources. Solutions for feeding the extra billions in the future are being studied and documented.^[110] One out of every seven people on the planet go to sleep hungry. Areas are subject to overpopulation, and 25,000 people die of malnutrition and hunger related diseases every day.

Fossil fuel dependence

While agricultural output has increased, energy consumption to produce a crop has also increased at a greater rate, so that the ratio of crops produced to energy input has decreased over time. Green Revolution techniques also heavily rely on chemical fertilizers, pesticides and herbicides, many of which are petroleum products, making agriculture increasingly reliant on petroleum.

Between 1950 and 1984, as the Green Revolution transformed agriculture around the globe, world grain production increased by 250%. The energy for the Green Revolution was provided by fossil fuels in the form of fertilizers (natural gas), pesticides (oil), and hydrocarbon fueled irrigation.^[111]

David Pimentel, professor of ecology and agriculture at Cornell University, and Mario Giampietro, senior researcher at the National Research Institute on Food and Nutrition (NRIFN), suggested in 1994 that the maximum U.S. population for a sustainable economy is 210 million. The study says that to achieve a sustainable economy and avert disaster, the United States must reduce its population by at least one-third, and world population will have to be reduced by two-thirds.^[112] The authors of the study believe that the mentioned agricultural crisis will only begin to affect us after 2020, and will not become critical until 2050. However, the US population in 2020 is already 330 million, with minimal food insecurity, calling their predictions into question.

Homogeneity in the global food supply

A small number of major crops, e.g. Soybean, have formed an increasing share of the food energy, protein, fat, and food weight eaten by the world's population over the past 50 years^[113]

Since 1961, human diets across the world have become more diverse in the consumption of major commodity staple crops, with a corollary decline in consumption of local or regionally important crops, and thus have become more homogeneous globally.^[113] The differences between the foods eaten in different countries were reduced by 68% between 1961 and 2009. The modern "global standard"^[113] diet contains an increasingly large percentage of a relatively small number of major staple commodity crops, which have increased substantially in the share of the total food energy (calories), protein, fat, and food weight that they provide to the world's human population, including wheat, rice, sugar, maize, soybean (by +284%^[114]), palm oil (by +173%^[114]), and sunflower (by +246%^[114]). Whereas nations used to consume greater proportions of locally or regionally important crops, wheat has become a staple in over 97% of countries, with the other global staples showing similar dominance worldwide. Other crops have declined sharply over the same period, including rye, yam, sweet potato (by −45%^[114]), cassava (by −38%^[114]), coconut, sorghum (by −52%^[114]) and millets (by −45%^[114]).^{[113][114][115]} Such crop diversity change in the human diet is associated with mixed effects on food security, improving under-nutrition in some regions but contributing to the diet-related diseases caused by over-consumption of macronutrients.^[113]

Price setting

On April 30, 2008, Thailand, one of the world's biggest rice exporters, announced the creation of the Organisation of Rice Exporting Countries with the potential to develop into a price-fixing cartel for rice. It is a project to organize 21 rice exporting countries to create a homonymous organisation to control the price of rice. The group is mainly made up of Thailand, Vietnam, Cambodia, Laos and Myanmar. The organization attempts to serve the purpose of making a "contribution to ensuring food stability, not just in an individual country but also to address food shortages in the region and the world". However, it is still questionable whether this organization will serve its role as an effective rice price fixing cartel, that is similar to OPEC's mechanism for managing petroleum. Economic analysts and traders said the proposal would go nowhere because of the inability of governments to cooperate with each other and control farmers' output. Moreover, countries that are involved expressed their concern that this could only worsen the food security.^{[116][117][118][119]}

Land use change

China needs not less than 120 million hectares of arable land for its food security. China has reported a surplus of 15 million hectares. By contrast, some 4 million hectares of conversion to urban use and 3 million hectares of contaminated land have also been reported.^[120] A survey found that 2.5% of China's arable land is too contaminated to grow food without harm.^[121] In Europe, the conversion of agricultural soil implied a net loss of potential, but the rapid loss in the area of arable soils appears to be economically meaningless because EU is perceived to be dependent on internal food supply anymore. During the period 2000–2006, the European Union lost 0.27% of its cropland and 0.26% of its crop productive potential. The loss of agricultural land during the same time was the highest in the Netherlands, which lost 1.57% of its crop production potential within six years. The figures are quite alarming for Cyprus (0.84%), Ireland (0.77%) and Spain (0.49%) as well.^[122] In Italy, in the Emilia-Romagna plain (ERP), the conversion of 15,000 hectare of agricultural soil (period 2003-2008) implied a net loss of 109,000 Mg per year of wheat, which accounts for the calories needed by 14% of ERP population (425,000 people). Such a loss in wheat production is just 0.02% of gross domestic product (GDP) of the Emilia-Romagna region, which is actually a minor effect in financial terms. Additionally, the income from the new land use is often much higher than the one guaranteed by agriculture, as in the case of urbanisation or extraction of raw materials.^[123]

Global catastrophic risks

As anthropogenic greenhouse gas emissions reduce the stability of the global climate,^[124] abrupt climate change could become more intense.^[125] The impact of an asteroid or comet larger than about 1 km diameter has the potential to block the sun globally,^[126] causing impact winter. Particles in the troposphere would quickly rain out, but particles in the stratosphere, especially sulfate, could remain there for years.^[126] Similarly, a supervolcanic eruption would reduce the potential of agricultural production from solar photosynthesis, causing volcanic winter. The Toba super volcanic eruption approximately 70,000 years ago may have nearly caused the extinction of humans^[126] (see Toba catastrophe theory). Again, primarily sulfate particles could block the sun for years. Solar blocking is not limited to natural causes as nuclear winter is also possible, which refers to the scenario involving widespread nuclear war and burning of cities that release soot into the stratosphere that would stay there for about 10 years.^[127] The high stratospheric temperatures produced by soot absorbing solar radiation would create near-global ozone hole conditions even for a regional nuclear conflict.^[128]

A sufficiently powerful geomagnetic storm could result in the sudden absence of access to electricity in large areas of the world. Because industrial farming is increasingly dependent on constant access to electricity, for example in precision livestock farming, a geomagnetic storm could potentially have devastating effects to the food production.^[129]

The World Food Programme has written that pandemics such as the COVID 19 pandemic are risk undermining the efforts of humanitarian and food security organizations to maintain food security. The Ebola outbreak in 2014 led to increases in the prices of staple foods in West Africa.^[130]

Agricultural subsidies in the United States

Agricultural subsidies are paid to farmers and agribusinesses to supplement their income, manage the supply of their commodities and influence the cost and supply of those commodities.^[131] In the United States, the main crops the government subsidizes contribute to the obesity problem; since 1995, $300 billion have gone to crops that are used to create junk food.^[132]

Taxpayers heavily subsidize corn and soy, which are primary ingredients in processed foods and fatty foods not encouraged by the government,^[132] and are also used to fatten livestock. Half of farmland is devoted to corn and soy, and the rest is wheat. Soy and corn can be found in sweeteners like high fructose corn syrup.^[132] Over $19 billion during the prior 18 years to 2013 was spent to incent farmers to grow the crops,^[132] raising the price of fruits and vegetables by about 40% and lowering the price of dairy and other animal products. Little land is used for fruit and vegetable farming.^[133]

Corn, a pillar of American agriculture for years, is now mainly used for ethanol, high fructose corn syrup and bio-based plastics.^[134] About 40 percent of corn is used for ethanol and 36% is used as animal feed.^[134] A tiny fraction of corn is used as a food source, and much of that fraction is used for high-fructose corn syrup, which is a main ingredient in processed, unhealthy junk food.^[134]

People who ate the most subsidized food had a 37% higher risk of being obese compared to people who ate the least amount of subsidized food.^[135] This brings up the concern that minority communities are more prone to risks of obesity due to financial limitations. The subsidies result in those commodities being cheap to the public, compared to those recommended by dietary guidelines.

President Trump proposed a 21% cut to government discretionary spending in the agriculture sector, which has met partisan resistance.^[136] This budget proposal would also reduce spending on the Special Supplement Nutrition Program for Women, Infants and Children, albeit less than President Obama did.^[136]

Children and food security

Bengali famine, 1943. The Japanese conquest of Burma cut off India's main supply of rice imports.^[137]

On April 29, 2008, a UNICEF UK report found that the world's poorest and most vulnerable children are being hit the hardest by climate change. The report, "Our Climate, Our Children, Our Responsibility: The Implications of Climate Change for the World's Children", says that access to clean water and food supplies will become more difficult, particularly in Africa and Asia.^[138]

In the United States

By way of comparison, in one of the largest food producing countries in the world, the United States, approximately one out of six people are "food insecure", including 17 million children, according to the U.S. Department of Agriculture in 2009.^[139] A 2012 study in the Journal of Applied Research on Children found that rates of food security varied significantly by race, class and education. In both kindergarten and third grade, 8% of the children were classified as food insecure, but only 5% of white children were food insecure, while 12% and 15% of black and Hispanic children were food insecure, respectively. In third grade, 13% of black and 11% of Hispanic children were food insecure compared to 5% of white children.^[140][141]

There are also regional variations in food security. Although food insecurity can be difficult to measure, 45% of elementary and secondary students in Maine qualify for free or reduced-price school lunch; by some measures Maine has been declared the most food-insecure of the New England states.^[142] Transportation challenges and distance are common barriers to families in rural areas who seek food assistance. Social stigma is another important consideration, and for children, sensitively administering in-school programs can make the difference between success and failure. For instance, when John Woods, co-founder of Full Plates, Full Potential,^[143] learned that embarrassed students were shying away from the free breakfasts being distributed at a school he was working with, he made arrangements to provide breakfast free of charge to all of the students there.^[144]

According to a 2015 Congressional Budget Office report on child nutrition programs, it is more likely that food insecure children will participate in school nutrition programs than children from food secure families.^[145] School nutrition programs, such as the National School Lunch Program (NSLP) and the School Breakfast Program (SBP) have provided millions of children access to healthier lunch and breakfast meals, since their inceptions in the mid-1900s. According to the Centers for Disease Control and Prevention, NSLP has served over 300 million, while SBP has served about 10 million students each day.^[146] Nevertheless, far too many qualifying students still fail to receive these benefits simply due to not submitting the necessary paperwork.^[147] Multiple studies have reported that school nutrition programs play an important role in ensuring students are accessing healthy meals. Students who ate school lunches provided by NLSP showed higher diet quality than if they had their own lunches.^[148] Even more, the USDA improved standards for school meals, which ultimately lead to positive impacts on children's food selection and eating habits.^[149]

Countless partnerships have emerged in the quest for food security. A number of federal nutrition programs exist to provide food specifically for children, including the Summer Food Service Program, Special Milk Program (SMP) and Child and Adult Care Food Program (CACFP), and community and state organizations often network with these programs. The Summer Food Program in Bangor, Maine, is run by the Bangor Housing Authority and sponsored by Good Shepherd Food Bank.^[142] In turn, Waterville Maine's Thomas College, for example, is among the organizations holding food drives to collect donations for Good Shepherd.^[150] Children whose families qualify for Supplemental Nutrition Assistance Program (SNAP) or Women, Infants, and Children (WIC) may also receive food assistance. WIC alone served approximately 7.6 million participants, 75% of which are children and infants.^[151]

Despite the sizable populations served by these programs, Conservatives have regularly targeted these programs for defunding.^[152] Conservatives' arguments against school nutrition programs include fear of wasting food and fraud from applications. On January 23, 2017, H.R.610 was introduced to the House by Republican Representative Steve King. The bill seeks to repeal a rule set by the Food and Nutrition Service of the Department of Agriculture, which mandates schools to provide more nutritious and diverse foods across the food plate.^[153] Two months later, the Trump administration released a preliminary 2018 budget that proposed a $2 billion cut from WIC.^[154]

Food insecurity in children can lead to developmental impairments and long term consequences such as weakened physical, intellectual and emotional development.^[155]

Food insecurity also related to obesity for people living in neighborhoods where nutritious food are unavailable or unaffordable.^[156]

Gender and food security

Gender inequality both leads to and is a result of food insecurity. According to estimates, girls and women make up 60% of the world's chronically hungry and little progress has been made in ensuring the equal right to food for women enshrined in the Convention on the Elimination of All Forms of Discrimination against Women.^[157][158] Women face discrimination both in education and employment opportunities and within the household, where their bargaining power is lower. Women's employment is essential for not only advancing gender equality within the workforce, but ensuring a sustainable future as it means less pressure for high birth rates and net migration.^[159] On the other hand, gender equality is described as instrumental to ending malnutrition and hunger.^[160]

Women tend to be responsible for food preparation and childcare within the family and are more likely to spend their income on food and their children's needs.^[161] Women also play an important role in food production, processing, distribution and marketing. They often work as unpaid family workers, are involved in subsistence farming and represent about 43% of the agricultural labor force in developing countries, varying from 20% in Latin America to 50% in Eastern and Southeastern Asia and Sub-Saharan Africa. However, women face discrimination in access to land, credit, technologies, finance and other services. Empirical studies suggest that if women had the same access to productive resources as men, women could boost their yields by 20–30%, raising the overall agricultural output in developing countries by 2.5 to 4%. While these are rough estimates, there would be a significant benefit of closing the gender gap on agricultural productivity.^[162] The gendered aspects of food security are visible along the four pillars of food security: availability, access, utilization and stability, as defined by the Food and Agriculture Organization.^[163]

The number of people affected by hunger is extremely high, with enormous effects on girls and women.^[164] There is sentiment that making this trend disappear should be a top priority for governments and international institutions.^[164] This is because food insecurity is an issue concerning equality, rights and social justice.^[164] Factors like capitalism, exploration of Indigenous lands all contribute to food insecurity for minorities and the people who are the most oppressed in various countries (women being one of these oppressed groups).^[164] Because girls and women are the most oppressed by the inequitable global economic processes that govern food systems and by global trends such as climate change, it is reflective of how institutions continue to place women in positions of disadvantage and impoverishment to make money and thrive on capitalizing the food system.^[164] When the government withholds food by raising its prices to amounts only privileged people can afford, they both benefit and are able to control the lower-class/marginalized people via the food market.^[164]

Use of genetically modified (GM) crops

One of the most up-and-coming techniques to ensuring global food security is the use of genetically modified (GM) crops. The genome of these crops can be altered to address one or more aspects of the plant that may be preventing it from being grown in various regions under certain conditions. Many of these alterations can address the challenges that were previously mentioned above, including the water crisis, land degradation, and the ever-changing climate.

In agriculture and animal husbandry, the Green Revolution popularized the use of conventional hybridization to increase yield by creating high-yielding varieties. Often, the handful of hybridized breeds originated in developed countries and were further hybridized with local varieties in the rest of the developing world to create high yield strains resistant to local climate and diseases.

The area sown to genetically engineered crops in developing countries is rapidly catching up with the area sown in industrial nations. According to the International Service for the Acquisition of Agri-biotech Applications (ISAAA), GM crops were grown by approximately 8.5 million farmers in 21 countries in 2005; up from 8.25 million farmers in 17 countries in 2004.

Opposition to GM crops

Some scientists question the safety of biotechnology as a panacea; agroecologists Miguel Altieri and Peter Rosset have enumerated ten reasons^[165] why biotechnology will not ensure food security, protect the environment, or reduce poverty. Reasons include:

• There is no relationship between the prevalence of hunger in a given country and its population
• Most innovations in agricultural biotechnology have been profit-driven rather than need-driven
• Ecological theory predicts that the large-scale landscape homogenization with transgenic crops will exacerbate the ecological problems already associated with monoculture agriculture
• And, that much of the needed food can be produced by small farmers located throughout the world using existing agroecological technologies.

Based on evidence from previous attempts, there is a likely lack of transferability of one type of GM crop from one region to another. For example, modified crops that have proven successful in Asia from the Green Revolution have failed when tried in regions of Africa.^[166] More research must be done regarding the specific requirements of growing a specific crop in a specific region.

There is also a drastic lack of education given to governments, farmers, and the community about the science behind GM crops, as well as suitable growing practices. In most relief programs, farmers are given seeds with little explanation and little attention is paid to the resources available to them or even laws that prohibit them from distributing produce. Governments are often not advised on the economic and health implications that come with growing GM crops, and are then left to make judgments on their own. Because they have so little information regarding these crops, they usually shy away from allowing them or do not take the time and effort required to regulate their use. Members of the community that will then consume the produce from these crops are also left in the dark about what these modifications mean and are often scared off by their 'unnatural' origins. This has resulted in failure to properly grow crops as well as strong opposition to the unknown practices.^[167]

A study published in June 2016 evaluated the status of the implementation of Golden Rice, which was first developed in the 1990s to produce higher levels of Vitamin A than its non-GMO counterparts. This strain of rice was designed so that malnourished women and children in third world countries who were more susceptible to deficiencies could easily improve their Vitamin A intake levels and prevent blindness, which is a common result. Golden Rice production was centralized to the Philippines, yet there have been many hurdles to jump in order to get production moving. The study showed that the project is far behind schedule and is not living up to its expectations. Although research on Golden Rice still continues, the country has moved forward with other non-GMO initiatives to address the Vitamin A deficiency problem that is so pervasive in that region.^[168][169]

Many anti-GMO activists argue that the use of GM crops decreases biodiversity among plants. Livestock biodiversity is also threatened by the modernization of agriculture and the focus on more productive major breeds. Therefore, efforts have been made by governments and non-governmental organizations to conserve livestock biodiversity through strategies such as Cryoconservation of animal genetic resources.^[170][171]

Support of GM crops

Many GM crop success stories exist, primarily in developed nations like the US, China, and various countries in Europe. Common GM crops include cotton, maize, and soybeans, all of which are grown throughout North and South America as well as regions of Asia.^[172] Modified cotton crops, for example, have been altered such that they are resistant to pests, can grown in more extreme heat, cold, or drought, and produce longer, stronger fibers to be used in textile production.^[173]

One of the biggest threats to rice, which is a staple food crop especially in India and other countries within Asia, is blast disease, which is a fungal infection that causes lesions to form on all parts of the plant.^[174] A genetically engineered strain of rice has been developed so that it is resistant to blast, greatly improving the crop yield of farmers and allowing rice to be more accessible to everyone.^[175] Some other crops have been modified such that they produce higher yields per plant or that they require less land for growing. The latter can be helpful in extreme climates with little arable land and also decreases deforestation, as fewer trees need to be cut down in order to make room for crop fields.^[176] Others yet have been altered such that they do not require the use of insecticides or fungicides. This addresses various health concerns associated with such pesticides and can also work to improve biodiversity within the area in which these crops are grown.^[177]

In a review of Borlaug's 2000 publication entitled Ending world hunger: the promise of biotechnology and the threat of antiscience zealotry,^[178] the authors argued that Borlaug's warnings were still true in 2010,^[179]

GM crops are as natural and safe as today's bread wheat, opined Dr. Borlaug, who also reminded agricultural scientists of their moral obligation to stand up to the antiscience crowd and warn policy makers that global food insecurity will not disappear without this new technology and ignoring this reality global food insecurity would make future solutions all the more difficult to achieve.

—Rozwadowski and Kagale

Research conducted by the GMO Risk Assessment and Communication of Evidence (GRACE) program through the EU between 2007 and 2013 focused on many uses of GM crops and evaluated many facets of their effects on human, animal, and environmental health.

The body of scientific evidence concluding that GM foods are safe to eat and do not pose environmental risks is wide. Findings from the International Council of Scientists (2003) that analyzed a selection of approximately 50 science-based reviews concluded that "currently available genetically modified foods are safe to eat," and "there is no evidence of any deleterious environmental effects having occurred from the trait/species combinations currently available."^[180] The United Nations Food and Agriculture Organization (FAO) supported the same consensus a year later in addition to recommending the extension of biotechnology to the developing world.^[181] Similarly, the Royal Society (2003) and British Medical Association (2004) found no adverse health effects of consuming genetically modified foods.^[182][183] These findings supported the conclusions of earlier studies by the European Union Research Directorate, a compendium of 81 scientific studies conducted by more than 400 research teams did not show “any new risks to human health or the environment, beyond the usual uncertainties of conventional plant breeding.”^[184] Likewise, the Organization for Economic Cooperation and Development in Europe (OECD) and the Nuffield Council on Bioethics (1999) did not find that genetically modified foods posed a health risk.^[185][186]

Approaches

By the United Nations

The UN Millennium Development Goals are one of the initiatives aimed at achieving food security in the world. The first Millennium Development Goal states that the UN "is to eradicate extreme hunger and poverty" by 2015.^[187] Olivier De Schutter, the UN Special Rapporteur on the Right to Food, advocates for a multidimensional approach to food security challenges. This approach emphasizes the physical availability of food; the social, economic and physical access people have to food; and the nutrition, safety and cultural appropriateness or adequacy of food.^[188]

By the Food and Agriculture Organization

The Food and Agriculture Organization of the United Nations stated in The State of Food Insecurity in the World 2003 that countries that have reduced hunger often had rapid economic growth, specifically in their agricultural sectors. These countries were also characterized as having slower population growth, lower HIV rates, and higher rankings in the Human Development Index.^[189] At that time, the FAO considered addressing agriculture and population growth vital to achieving food security. In The State of Food Insecurity in the World 2012, the FAO restated its focus on economic growth and agricultural growth to achieve food security and added a focus on the poor and on "nutrition-sensitive" growth. For example, economic growth should be used by governments to provide public services to benefit poor and hungry populations. The FAO also cited smallholders, including women, as groups that should be involved in agricultural growth to generate employment for the poor. For economic and agricultural growth to be "nutrition-sensitive", resources should be utilized to improve access to diverse diets for the poor as well as access to a safe water supply and to healthcare.^[22]

The FAO has proposed a "twin track" approach to fight food insecurity that combines sustainable development and short-term hunger relief. Development approaches include investing in rural markets and rural infrastructure.^[5] In general, the FAO proposes the use of public policies and programs that promote long-term economic growth that will benefit the poor. To obtain short-term food security, vouchers for seeds, fertilizer, or access to services could promote agricultural production. The use of conditional or unconditional food or cash transfers was another approach the FAO noted. Conditional transfers could include school feeding programs, while unconditional transfers could include general food distribution, emergency food aid or cash transfers. A third approach is the use of subsidies as safety nets to increase the purchasing power of households. The FAO stated that "approaches should be human rights-based, target the poor, promote gender equality, enhance long-term resilience and allow sustainable graduation out of poverty."^[22]

The FAO noted that some countries have been successful in fighting food insecurity and decreasing the number of people suffering from undernourishment. Bangladesh is an example of a country that has met the Millennium Development Goal hunger target. The FAO credited growth in agricultural productivity and macroeconomic stability for the rapid economic growth in the 1990s that resulted in an increase in food security. Irrigation systems were established through infrastructure development programs. Two programs, HarvestPlus and the Golden Rice Project, provided biofortified crops in order to decrease micronutrient deficiencies.^[7]

World Food Day was established on October 16, in honor of the date that the FAO was founded in 1945. On this day, the FAO hosts a variety of event at the headquarters in Rome and around the world, as well as seminars with UN officials.^[27]

By the World Food Programme

Fight Hunger: Walk the World campaign is a United Nations World Food Programme initiative.

The World Food Programme (WFP) is an agency of the United Nations that uses food aid to promote food security and eradicate hunger and poverty. In particular, the WFP provides food aid to refugees and to others experiencing food emergencies. It also seeks to improve nutrition and quality of life to the most vulnerable populations and promote self-reliance.^[190] An example of a WFP program is the "Food For Assets" program in which participants work on new infrastructure, or learn new skills, that will increase food security, in exchange for food.^[191] The WFP and the Government of Kenya have partnered in the Food For Assets program in hopes of increasing the resilience of communities to shocks.^[192]

Global partnerships to achieve food security and end hunger

In April 2012, the Food Assistance Convention was signed, the world's first legally binding international agreement on food aid. The May 2012 Copenhagen Consensus recommended that efforts to combat hunger and malnutrition should be the first priority for politicians and private sector philanthropists looking to maximize the effectiveness of aid spending. They put this ahead of other priorities, like the fight against malaria and AIDS.^[193]

The main global policy to reduce hunger and poverty are the recently approved Sustainable Development Goals. In particular Goal 2: Zero Hunger sets globally agreed targets to end hunger, achieve food security and improved nutrition and promote sustainable agriculture by 2030.^[194] A number of organizations have formed initiatives with the more ambitious goal to achieve this outcome in only 10 years, by 2025:

• In 2013 Caritas International started a Caritas-wide initiative aimed at ending systemic hunger by 2025. The One human family, food for all campaign focuses on awareness raising, improving the effect of Caritas programs and advocating the implementation of the Right to Food.^[195]
• The partnership Compact2025,^[196] led by IFPRI with the involvement of UN organisations, NGOs and private foundations^[197] develops and disseminates evidence-based advice to politicians and other decision-makers aimed at ending hunger and undernutrition in the coming 10 years, by 2025.^[198] It bases its claim that hunger can be ended by 2025 on a report by Shenggen Fan and Paul Polman that analyzed the experiences from China, Vietnam, Brazil and Thailand and concludes that eliminating hunger and undernutrition was possible by 2025.^[199]
• In June 2015, the European Union and the Bill & Melinda Gates Foundation have launched a partnership to combat undernutrition especially in children. The program will initially be implemented in Bangladesh, Burundi, Ethiopia, Kenya, Laos and Niger and will help these countries to improve information and analysis about nutrition so they can develop effective national nutrition policies.^[200]
• The Food and Agriculture Organization of the UN has created a partnership that will act through the African Union's CAADP framework aiming to end hunger in Africa by 2025. It includes different interventions including support for improved food production, a strengthening of social protection and integration of the Right to Food into national legislation.^[201]

By the United States Agency for International Development

The United States Agency for International Development (USAID) proposes several key steps to increasing agricultural productivity, which is in turn key to increasing rural income and reducing food insecurity.^[202] They include:

• Boosting agricultural science and technology. Current agricultural yields are insufficient to feed the growing populations. Eventually, the rising agricultural productivity drives economic growth.
• Securing property rights and access to finance
• Enhancing human capital through education and improved health
• Conflict prevention and resolution mechanisms and democracy and governance based on principles of accountability and transparency in public institutions and the rule of law are basic to reducing vulnerable members of society.

Since the 1960s, the U.S. has been implementing a food stamp program (now called the Supplemental Nutrition Assistance Program) to directly target consumers who lack the income to purchase food. According to Tim Josling, a Senior Fellow at the Freeman Spogli Institute for International Studies, Stanford University, food stamps or other methods of distribution of purchasing power directly to consumers might fit into the range of international programs under consideration to tackle food insecurity.^[203]

Improving agricultural productivity to benefit the rural poor

A farmer on the outskirts of Lilongwe (Malawi) prepares a field for planting.

There are strong, direct relationships between agricultural productivity, hunger, poverty, and sustainability. Three-quarters of the world's poor live in rural areas and make their living from agriculture. Hunger and child malnutrition are greater in these areas than in urban areas. Moreover, the higher the proportion of the rural population that obtains its income solely from subsistence farming (without the benefit of pro-poor technologies and access to markets), the higher the incidence of malnutrition. Therefore, improvements in agricultural productivity aimed at small-scale farmers will benefit the rural poor first. Food and feed crop demand is likely to double in the next 50 years, as the global population approaches nine billion. Growing sufficient food will require people to make changes such as increasing productivity in areas dependent on rainfed agriculture; improving soil fertility management; expanding cropped areas; investing in irrigation; conducting agricultural trade between countries; and reducing gross food demand by influencing diets and reducing post-harvest losses.

According to the Comprehensive Assessment of Water Management in Agriculture, a major study led by the International Water Management Institute (IWMI), managing rainwater and soil moisture more effectively, and using supplemental and small-scale irrigation, hold the key to helping the greatest number of poor people. It has called for a new era of water investments and policies for upgrading rainfed agriculture that would go beyond controlling field-level soil and water to bring new freshwater sources through better local management of rainfall and runoff.^[204] Increased agricultural productivity enables farmers to grow more food, which translates into better diets and, under market conditions that offer a level playing field, into higher farm incomes. With more money, farmers are more likely to diversify production and grow higher-value crops, benefiting not only themselves but the economy as a whole.^[187]

It may be that an alliance between the emergency food program and community-supported agriculture is beneficial, as some countries' food stamps cannot be used at farmer's markets and places where food is less processed and grown locally.^[205] The gathering of wild food plants appears to be an efficient alternative method of subsistence in tropical countries, which may play a role in poverty alleviation.^[206]

Large-scale food stockpiling

The minimum annual global wheat storage is approximately two months.^[207] To counteract the severe food security issues caused by global catastrophic risks, years of food storage has been proposed.^[208] Though this could ameliorate smaller scale problems like regional conflict and drought, it would exacerbate current food insecurity by raising food prices.

Agricultural insurances

Insurance is a financial instrument, which allows exposed individuals to pool resources to spread their risk. They do so by contributing premium to an insurance fund, which will indemnify those who suffer insured loss. This procedure reduces the risk for an individual by spreading his/her risk among the multiple fund contributors. Insurance can be designed to protect many types of individuals and assets against single or multiple perils and buffer insured parties against sudden and dramatic income or asset loss.

Crop insurance is purchased by agricultural producers to protect themselves against either the loss of their crops due to natural disasters. Two type of insurances are available:^[209] claim-based insurances and index-based insurances. In particular, in poor countries facing food security problems, index-based insurances offer some advantages, including indices that can be derived from globally available satellite images that correlate well with what is insured. These indices can be delivered at low cost, and the insurance products open up new markets that are not served by claim-based insurances.^{[relevant? – discuss]}

An advantage of index-based insurance is that it can potentially be delivered at lower cost. A significant barrier that hinders uptake of claim-based insurance is the high transaction cost for searching for prospective policyholders, negotiating and administering contracts, verifying losses and determining payouts. Index insurance eliminates the loss verification step, thereby mitigating a significant transaction cost. A second advantage of index-based insurance is that, because it pays an indemnity based on the reading of an index rather than individual losses, it eliminates much of the fraud, moral hazard and adverse selection, which are common in classical claim-based insurance. A further advantage of index insurance is that payments based on a standardized and indisputable index also allow for a fast indemnity payment. The indemnity payment could be automated, further reducing transaction costs.^{[relevant? – discuss]}

Basis risk is a major disadvantage of index-based insurance. It is the situation where an individual experiences a loss without receiving payment or vice versa. Basis risk is a direct result of the strength of the relation between the index that estimates the average loss by the insured group and the loss of insured assets by an individual. The weaker this relation the higher the basis risk. High basis risk undermines the willingness of potential clients to purchase insurance. It thus challenges insurance companies to design insurances such as to minimize basis risk.^{[relevant? – discuss]}

Food Justice Movement

Main page: Social:Food Justice Movement

The Food Justice Movement has been seen as a unique and multifaceted movement with relevance to the issue of food security. It has been described as a movement about social-economic and political problems in connection to environmental justice, improved nutrition and health, and activism. Today, a growing number of individuals and minority groups are embracing the Food Justice due to the perceived increase in hunger within nations such as the United States as well as the amplified effect of food insecurity on many minority communities, particularly the Black and Latino communities.^[210]

A number of organizations have either championed the Food Justice Cause or greatly impacted the Food Justice space. An example of a prominent organization within the food justice movement has been the Coalition of Immokalee Workers, which is a worker-based human rights organization that has been recognized globally for its accomplishments in the areas of human trafficking, social responsibility and gender-based violence at work. The Coalition of Immoaklee Workers most prominent accomplishment related to the food justice space has been its part in implementing the Fair Food Program, which increased the pay and bettered working conditions of farm workers in the tomato industry who had been exploited for generations. This accomplishment provided over 30,000 workers more income and the ability to access better and more healthy foods for themselves and their families. Another organization in the food justice space is the Fair Food Network, an organization that has embraced the mission of helping families who need healthy food gain access to it while also increasing the livelihood for farmers in America and growing local economies. Started by Oran B. Hesterma, the Fair Food Network has invested over $200 million in various projects and initiatives, such as the Double Up Food Bucks program, to help low-income and minority communities access healthier food.^[211]

Bees

Bees and other pollinating insects are currently improving the food production of 2 billion small farmers worldwide, helping to ensure food security for the world's population. Research shows that if pollination is managed well on small diverse farms, with all other factors being equal, crop yields can increase by a significant median of 24 percent.^[212]

How animal pollinators positively affect fruit condition and nutrient content is still being discovered.^[213]

Model

An example of a city that has overcome challenges and achieved improved sustainability practices while immensely decreasing food insecurity is Lisbon. Lisbon, the capital of Portugal, was awarded as the 2020 European Green Leaf Award Winner for its notable sustainable land use, transport, green growth and eco and waste innovations.^[214] The 2010 to 2014 Portuguese financial crisis, a prominent obstacle for Portugal caused by factors such as the global recession, resulted in increased unemployment rates and reduced household budgets.^[215] As a product, adequate food intake was evidently inhibited. However, Lisbon demonstrated that sustainability and economic growth can go hand in hand. Measures were taken place such as the ReFood Movement, a food waste prevention initiative, and the Municipal Plan Against Food Wastage program.^[216]

Criticism

(As of 2015), the concept of food security has mostly focused on food calories rather than the quality and nutrition of food. The concept of nutrition security evolved over time. In 1995, it has been defined as "adequate nutritional status in terms of protein, energy, vitamins, and minerals for all household members at all times".^[217]:16
