Insect Populations Halved in Some Areas by Warming Climate and Intensive Agriculture

A study published in Nature by University College London compared insect biodiversity in different areas depending on how intensive agriculture is in the area, as well as how much historic climate warming the local area has experienced. Researchers found that in areas with high-intensity agriculture and substantial climate warming, the number of insects was 49% lower than in the most natural habitats with no recorded climate warming, while the number of different species was 29% lower. In areas of low-intensity agriculture and substantial climate warming, having nearby natural habitat buffered the losses: where 75% of the land was covered by natural habitat, insect abundance only declined by 7%, compared to a 63% reduction in comparable areas with only 25% natural habitat cover.
