This book collects the findings of a group of scientists and economists who have taken stock of climate change impacts on food and agriculture at global and regional levels over the past two decades.

A new artificial intelligence (AI) tool available for free in a smartphone app can predict near-term crop productivity for farmers in Africa and may help them protect their staple crops—such as maize, cassava and beans—in the face of climate warming, according to Penn State researchers.

Beekeepers have been losing an average of 30% of overwintered colonies for nearly 15 years. It is expensive to overwinter colonies in areas where winter temperatures stay above freezing. A less expensive practice of overwintering bee colonies in cold storage is becoming popular.

Wild plants grow in all agricultural fields that reduce crop yields by competing with them for water, light and nutrients. To control them, the most frequent management among producers is based on the use of herbicides. These agrochemicals are most effective when applied at the time weeds barely emerge.

Researchers from the University of Cambridge's Sainsbury Laboratory (SLCU) and Department of Plant Sciences have discovered that drought stress triggers the activity of a family of jumping genes (Rider retrotransposons) previously known to contribute to fruit shape and colour in tomatoes.

Iowa State University scientists are working toward a future in which farmers can use unmanned aircraft to spot, and even predict, disease and stress in their crops. Their vision relies on machine learning, an automated process in which technology can help farmers respond to plant stress more efficiently.
