Multiple breadbasket failure
A multiple breadbasket failure is the simultaneous disruption of grain production in several major agricultural regions globally, primarily due to acute climate events. This phenomenon has gained increasing attention[clarification needed] in climate risk assessment and food security studies, particularly as climate change threatens to increase its likelihood in coming decades, potentially resulting in international food insecurity, economic crises, and significant civil and political unrest.
Multiple breadbasket failure occurs when concurrent climate events simultaneously impact grain production in multiple key agricultural regions, known as breadbaskets, thus significantly affecting global food supply. These regions are primarily responsible for producing the world's four main grain crops: rice, wheat, maize, and soybeans. Global nutrition heavily relies on these primary grains, which constitute nearly half of the average global caloric intake, of which rice and wheat alone contribute 19% and 18% of global calories respectively.
The world's concentrated dependence on a small number of primary crops increases systemic vulnerability. Global caloric intake could be significantly reduced if climate conditions significantly reduce the yield of one primary crop, compared to a more diverse variety of crops that could result in greater flexibility with what climate conditions allow to grow and have high yields.
Food production exhibits significant geographic concentration, with approximately 60% of global food production occurring in only five nations: China, the United States, India, Brazil, and Argentina. Within these nations, production is further concentrated in specific regions. For instance, five states in north India accounted for 88% of the country's wheat production, while five Midwestern states generate 61% of U.S. corn output, according to a June 2016 United States Department of Agriculture report.
A 2012 report by the United Nations found that developing countries increasingly depend on grain imports, due to international market purchases frequently being more economically viable than domestic production. Nations such as Mexico, Egypt, Algeria, and Saudi Arabia maintain significant grain import requirements, while China heavily relies on soybean imports.[clarification needed]
While grain storage serves as a buffer against production shortfalls, current global storage capacity may prove insufficient to withstand major production shocks, despite historically high present-day levels.
Research and statistical analysis conducted by the McKinsey Global Institute indicates that ongoing climate change is increasing both the likelihood and severity of future multiple breadbasket failures. A 2020 report by the institute estimated that by 2030, the probability of a greater than 15% shock to global grain production is projected to double, rising from a 1-in-100 year event to a 1-in-50 year occurrence and representing an 18% likelihood of such an event occurring within the 2030s.
Furthermore, when extreme events push agricultural systems beyond critical environmental thresholds, they can induce rapid, nonlinear changes that may be difficult or impossible to reverse. This nonlinearity could manifest through sudden shifts in crop viability across regions, changes in soil fertility, or alterations to regional water availability that affect agricultural productivity. These interactions are particularly significant in major food-producing regions, where concurrent extreme events can create synchronized stress on global food production.
