The study by Lesk, Rowhani, and Ramankutty examines the global impact of extreme weather disasters (EWDs) on crop production from 1964 to 2007. Using Superposed Epoch Analysis (SEA), they estimate national cereal production losses due to droughts and extreme heat events, finding that these events significantly reduced cereal production by 9-10%. Droughts were associated with both reduced harvested area and yields, while extreme heat mainly decreased yields. The study also highlights that more recent droughts have had a greater impact on cereal production than earlier ones, and that developed countries suffer more from these extreme events. The findings emphasize the need for robust scientific information to guide disaster risk reduction and adaptation efforts to protect vulnerable populations and ensure global food security.The study by Lesk, Rowhani, and Ramankutty examines the global impact of extreme weather disasters (EWDs) on crop production from 1964 to 2007.
