A climate change modeling paper published in the latest issue of Nature, an internationally renowned academic journal, found that most staple crops may suffer severe yield losses due to climate change, even if mitigation measures to limit the impact of climate change are taken into account. The study evaluated six staple crops, corn, soybeans, rice, wheat, cassava and sorghum, and found that only rice might be able Untuk menghindari kerugian parah .
The paper introduced that climate change is expected to affect the global food system, but people are still uncertain about the extent of its impact and how adaptation measures such as changing agricultural methods will mitigate these impacts. Previous studies have focused on results in specific regions such as the United States, but have reached conflicting conclusions on the impact of adaptation measures. Some modeling shows that adaptation measures may affect global Produktivitas pertanian . Namun, beberapa penelitian telah berfokus pada adaptasi produsen dunia nyata di tingkat global .
Dalam penelitian ini, Andrew Hultgren, penulis yang berkoresponden dari makalah ini, University of Illinois di Urbana-Champaign, dan Solomon Hsiang dari Stanford University, bersama dengan kolaborator, menyusun dataset enam panen stapel, termasuk DATAMER PROPOSION, SELEBAN, PAS, PAS, GINGKAT, CASSAVA DAN LANGGHUM, TOGONGER DATA DAGIONS. Langkah -langkah di abad ke -21 .
The authors of the paper estimate that for every 1℃increase in temperature above pre-industrial levels, the daily output per person will decrease by 120 calories, equivalent to 4.4% of the current daily consumption. They believe that under a high-emission scenario, corn production in the United States, eastern China, central Asia, southern Africa, and the Middle East may decrease by up to 40% by the end Dari abad ke -21, kerugian gandum di Eropa, Afrika, dan Amerika Selatan akan menjadi 15%-25%, dan kerugian gandum di Cina, Rusia, Amerika Serikat, dan Kanada akan menjadi 30%{11}}%{17}} mereka juga mencatat bahwa pertumbuhan pendapatan dan implementasi strategi adaptasi dapat mengurangi kerugian global oleh Global oleh Global oleh Global, dan implementasi dari a adaptasi. langkah -langkah.
The authors said the study found that the decline of today's breadbasket regions with suitable climates but limited adaptive capacity would drive global impacts, with significant losses in low-income regions. They concluded that further adaptation measures and consideration of cropland expansion may be needed in the future to ensure food security and mitigate climate impacts.
