The global agricultural system is increasingly at risk as climate change raises the likelihood of simultaneous failures in major breadbasket regions, such as the North American Prairies and the Ukrainian Steppe. This interconnectedness, while beneficial in times of localized stress, becomes a liability when multiple regions experience droughts or other climate-related challenges simultaneously. A recent study suggests that the chance of concurrent droughts in key maize-producing areas could be as high as 60% this century, driven by long-term drying trends in Brazil, Europe, and the United States. The concentration of power among a few large agricultural firms, which dominate seed and pesticide markets, further complicates the situation. When one region faces a harvest failure, it can lead to export restrictions and heightened prices globally, affecting countries dependent on imports. The modern food system was built on the assumption that agricultural risks would be unevenly distributed geographically. However, as climate change tests this assumption, the potential for widespread food shortages and increased prices looms larger.
