Until now, most research on climate change and agriculture has focused on crops, not the people who cultivate the crops. A new study looks at the future potential impacts of global warming on both crop yields and farmworkers for a more complete picture of the effects of climate change to the agricultural sector. The study shows that, worldwide, labor and yield impacts are equally important at +3 ◦C warming, with the widely overlooked labor impacts dominant in two of the most vulnerable regions: sub-Saharan Africa and Southeast Asia.
