Combining the Effects of Climate Change and Agriculture on Mammal Populations

by Coco Coyle

In concert with the effects of climate change, some agricultural practices are having an unanticipated combined effect on ecosystems and biodiversity. Brodie (2016) showed that agricultural expansion coupled with climate change will have a more intense effect on the mammals in the extremely biodiverse region of Southeast Asia than either cause alone. Rising temperatures allow farmers to expand the growing region for cold-sensitive crops like the non-native oil-palm trees. While rising temperatures themselves do not disrupt the region’s mammalian species, the destruction of native forests in place of new agricultural areas would reduce mammal ranges by 47-67% by 2070. This is 3-4 times the reduction predicted considering direct effects from conversion of natural forest to plantations alone. In this study Brodie calls for a greater investigation of the combined effects of climate change and agriculture on biodiversity. Continue reading
