Over the past few decades, it has become obvious that climate change, and consequent extreme weather events, can wreak havoc on crop yields. Concerningly, there is a large disparity in agricultural vulnerability between developed and developing countries. In a new study, researchers have looked at major food grains in India to understand the long- and short-term effects of climate change on crop yields.

Agricultural scientists who study climate change often focus on how increasing atmospheric carbon dioxide levels will affect crop yields. But rising temperatures are likely to complicate the picture, researchers report in a new review of the topic.

Scientists have proposed a range of technological options for sustainable, productive and resilient agriculture, providing multiple ways to remove CO2 from the atmosphere and helping to directly mitigate climate change.

Five years ago, the United Nations committed to achieving the Sustainable Development Goal of Zero Hunger by 2030. Since then, however, world hunger has continued to rise. Nearly 9 percent of our global population is now undernourished, according to a 2020 report from the FAO, and climate variability is a leading factor driving us off course.

Recent research has shown that rising carbon dioxide levels will likely boost yields, but at the cost of nutrition. A new study in Plant Journal from the University of Illinois, U.S.

The societal stakes for assessing climate change impacts on agriculture and food supply are incredibly high. To meet this need, sophisticated computer models have been developed that simulate how crops grow and are influenced by their environment. They are like a three-dimensional jigsaw puzzle, with a multitude of interacting factors that must be correctly assembled.
