Norman Ernest Borlaug (born March 25, 1914, near Saude, Iowa, U.S.—died September 12, 2009, Dallas, Texas) was an American agricultural scientist and plant pathologist, and winner of the Nobel Prize for Peace in 1970. Known as the “Father of the Green Revolution,” Borlaug helped lay the groundwork for agricultural technological advances that alleviated world hunger.

Borlaug studied plant biology and forestry at the University of Minnesota and earned a Ph.D. in plant pathology there in 1942. He began working with the DuPont Company in 1942 but was soon recruited as a research scientist in charge of wheat improvement for the Rockefeller Foundation’s Cooperative Mexican Agricultural Program in Mexico, where he worked from 1944 to 1960. Seeking to assist impoverished farmers who struggled with diseased and low-producing crops, Borlaug experimented with novel varieties of wheat, creating disease-resistant strains that could withstand the harsh climate. That work was founded on earlier discoveries of ways to induce genetic mutations in plants, and his methods led to modern plant breeding.

The Green Revolution resulted in increased production of food grains (especially wheat and rice) and was in large part due to the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century with Borlaug’s work. At a research station at Campo Atizapan, he developed a short-stemmed (“dwarf”) strain of wheat that dramatically increased crop yields. Previously, taller wheat varieties would break under the weight of the heads if production was increased by chemical fertilizers. Borlaug’s short-stemmed wheat could withstand the increased weight of fertilized heads and was a key element in the Green Revolution in developing countries. Wheat production in Mexico multiplied threefold owing to this and other varieties.

Faces of Science

Following Borlaug’s success in Mexico, the Indian and Pakistani goverments requested his assistance, and with the support of the Rockefeller Foundation and the Food and Agriculture Organization of the United Nations (FAO), Borlaug began his agricultural revolution in Asia. With India and Pakistan facing food shortages due to rapid population growth, the importation of Borlaug’s dwarf wheat in the mid-1960s was responsible for a 60 percent increase in harvests there, helping both countries to become agriculturally self-sufficient. His work in developing countries, especially on the Indian subcontinent, is estimated to have saved as many as one billion people from starvation and death.

Borlaug also created a wheat-rye hybrid known as triticale, and his methods were used by others to develop new varieties of highly productive rice. The increased yields resulting from Borlaug’s new strains empowered many developing countries, though their use required large amounts of chemical fertilizers and pesticides. These high-yielding crops raised concerns about cost and potentially harmful environmental effects, though Borlaug argued that uncontrolled population growth had necessitated such production methods. Although newer varieties of food grains have been developed to be high-yielding and also resistant to local pests and diseases, modern agriculture has yet to achieve environmental sustainability in the face of an ever-growing human population.

Borlaug served as director of the Inter-American Food Crop Program (1960–63) and as director of the International Maize and Wheat Improvement Center, Mexico City, from 1964 to 1979. In 1986 Borlaug created the World Food Prize to honour individuals who have contributed to improving the availability and quality of food worldwide. In constant demand as a consultant, Borlaug served on numerous committees and advisory panels on agriculture, population control, and renewable resources. He also taught at Texas A&M University (1984–2009), where the Norman Borlaug Institute for International Agriculture was established in 2006. His numerous other honours include the Presidential Medal of Freedom (1977), the National Medal of Science (2004), the Congressional Gold Medal (2006), and the United Nations FAO Agricola Medal (2010).

global food security, the availability of and access to resources in sufficient quantities to achieve adequate nutrition for the world population. According to the United Nations Food and Agriculture Organization, in 2022 some 2.4 billion people—about 29.6 percent of the world population—experienced moderate to severe limitations in access to food. Such widespread food insecurity is linked to various factors, especially conflict, local and national economic decline, poorly performing agricultural markets, and increased rates of inequality and poverty.

Components of food security

Ensuring food security requires fulfillment of multiple aspects of food production, including availability, access, utilization, and stability. Availability of food is closely linked to the global food supply, which is influenced by both planned factors and unexpected events, ranging from sanctions and trade restrictions to outbreaks of foodborne illness, natural disasters, and wars. Countries with secure economies are better equipped to withstand interruptions in food supply without marked increases in food insecurity.

Sufficient availability of food, however, does not necessarily ensure widespread access or fair allotment; an individual’s ability to access food depends on physical and economical factors. Moreover, the utilization of food can vary widely, particularly in the way that food is prepared and distributed and in the way that the human body utilizes nutrients. Stability of these components over time is critical—food insecurity often occurs episodically and is triggered by an event such as crop failure.

Recent declines in food security

The Global Food Security Index reviews the affordability, availability, sustainability, and quality and safety of food annually in more than 100 countries. Countries with consistently high ratings of food security include Finland, France, and Sweden. In the early 2020s, after nearly a decade of mostly positive increases, food security ratings fell worldwide. Countries in Africa and Asia are disproportionately affected by food shortages, owing to high levels of poverty, harsh climatic conditions, inequality, high population growth, and weak national economies.

Declines in global food security in the 2020s were attributed in particular to the economic impacts of the coronavirus disease 2019 (COVID-19) pandemic, which began in 2020. Russia’s invasion of Ukraine in 2022 worsened the global food crisis as well, by disrupting agricultural supplies and causing significant increases in the price of wheat, corn (maize), fuel, and fertilizer. Other threats to food security include world population growth, drought, and the volatility of inflation and food prices. By 2023 most of the world was experiencing significant increases in inflation and trade restrictions. Some countries attempted to regulate prices domestically to control inflation but in the process inadvertently worsened the global food market. Increases in natural disasters and extreme weather events and the effects of armed conflicts compounded food shortages.

Strategies to improve food security

Food security can be improved in part by focusing on sustainable agriculture, which can help mitigate effects of climate change, because of its emphasis on diversity in agricultural planning. Sustainable food systems are better able to withstand fluctuations in climate and disruptions to the supply chain than traditional agricultural approaches can. The incorporation of permaculture, such as using trees as windbreaks or firebreaks and planting many different varieties of plant species, can also help safeguard yields.

Other ways to increase global food security involve promoting food safety measures and reducing food waste and losses, especially post-harvest losses—about one-third of food produced globally is wasted after harvesting. Post-harvest loss is primarily a problem in developed countries, where many consumers are not interested in purchasing cosmetically imperfect produce.

There also have been efforts to expand consumer interest in and access to less-conventional protein sources, such as insects. Cricket flour, for example, is considered a useful source of protein and has anti-inflammatory effects. Insects can be raised and harvested sustainably, with very little environmental impact.

Additionally, supporting governmental policies that address the root causes of poverty and make food more affordable and accessible for vulnerable households can also reduce food insecurity. In about half of U.S. states, the value of food assistance funds is doubled when it is spent on produce at farmers markets and farm stands; such programs have the added benefit of supporting farmers’ incomes while helping to meet consumers’ nutritional needs.
