Underscoring the necessity of aggressive action to combat human-caused global warming, research published Wednesday warns that the majority of the world\u0026#039;s wheat fields are at risk of enduring \u0022severe, prolonged, and near-simultaneous droughts\u0022 by the end of the century—raising serious concerns about future food insecurity and political instability.\u0022Even under the ambitious mitigation scenario aimed to stabilize global warming at 2°C compared to pre-industrial levels, the increase in the frequency and extent of adverse weather extremes and related shocks on the production side would be unprecedented.\u0022—study\u0022If only one country or region sees a drought there is less impact,\u0022 said study co-author Song Feng of the University of Arkansas. \u0022But if multiple regions are affected simultaneously, it can affect global production and food prices, and lead to food insecurity.\u0022The peer-reviewed study, published in the journal Science Advances, was conducted by team of researchers from the United States, Europe, and Asia.Wheat accounts for about 20 percent of all calories consumed by humans worldwide and the global demand for wheat products such as cereal is expected to rise in the coming decades, according to the U.N. Food and Agriculture Organization (FAO). Recognizing humanity\u0026#039;s reliance on the crop as a key food source, the study\u0026#039;s researchers analyzed various climate models to assess the rising risk of drought in wheat-producing regions.\u0022Global warming is expected to increase the frequency and intensity of severe water scarcity (SWS) events, which negatively affect rain-fed crops such as wheat,\u0022 the study says. \u0022Our projections show that, without climate change mitigation... up to 60 percent of the current wheat-growing area will face simultaneous SWS events by the end of this century, compared to 15 percent today.\u0022Referencing a key goal of the Paris climate accord, researchers warn that \u0022even under the ambitious mitigation scenario aimed to stabilize global warming at 2°C compared to pre-industrial levels, the increase in the frequency and extent of adverse weather extremes and related shocks on the production side would be unprecedented.\u0022The impact on food prices and security will depend on multiple factors. As the study explains, \u0022recent evidence suggests that variations in crop product prices are linked to simultaneously challenging economic factors, such as oil prices and exchange rates, as well as the occurrence of large-scale droughts and corresponding market and policy responses.\u0022Reuters reported, citing co-author Petr Havlik, that \u0022Africa would be the most affected region by the middle of the century.\u0022Europe, the United States, and Russia would be severely hit, said Havlik, deputy director at Austria\u0026#039;s International Institute for Applied Systems Analysis.Africa is not a major wheat producer, but the crop provides 14 percent of the calories consumed by the continent\u0026#039;s population, which is projected to double by 2050, Havlik said.FAO projects that by 2050, global demand for cereals will increase by 43 percent compared with the 2006 level, \u0022which is fairly conservative compared to other projections,\u0022 and \u0022will predominantly come from developing countries,\u0022 the study notes. If those nations can\u0026#039;t sustainably boost their supply, they will increasingly depend on imports.Researchers warn that \u0022these developments may increase food insecurity and, consequently, political instability and migration.\u0022The new study \u0022contributes substantially to the neglected area of climate extremes in agriculture, as it brings new data to light on how likely the shocks caused by drought might be in near future,\u0022 Havlik told Bloomberg.The research follows a landmark U.N. report from August which called for a global overhaul of the ways humans use land—including forestry, agriculture, and industrial and urban development—to meet the food needs of the world\u0026#039;s growing human population and ensure a habitable planet.
