Bioenergy cropland expansion may offset positive effects of climate change mitigation for global vertebrate diversity.

Hof, Christian and Voskamp, Alke and Biber, Matthias F. and Böhning-Gaese, Katrin and Engelhardt, Eva Katharina and Niamir, Aidin and Willis, Stephen G. and Hickler, Thomas (2018) 'Bioenergy cropland expansion may offset positive effects of climate change mitigation for global vertebrate diversity.', Proceedings of the National Academy of Sciences of the United States of America., 115 (52). pp. 13294-13299.


Climate and land-use change interactively affect biodiversity. Large-scale expansions of bioenergy have been suggested as an important component for climate change mitigation. Here we use harmonized climate and land-use projections to investigate their potential combined impacts on global vertebrate diversity under a low- and a high-level emission scenario. We combine climate-based species distribution models for the world’s amphibians, birds, and mammals with land-use change simulations and identify areas threatened by both climate and land-use change in the future. The combined projected effects of climate and land-use change on vertebrate diversity are similar under the two scenarios, with land-use change effects being stronger under the low- and climate change effects under the high-emission scenario. Under the low-emission scenario, increases in bioenergy cropland may cause severe impacts in biodiversity that are not compensated by lower climate change impacts. Under this low-emission scenario, larger proportions of species distributions and a higher number of small-range species may become impacted by the combination of land-use and climate change than under the high-emission scenario, largely a result of bioenergy cropland expansion. Our findings highlight the need to carefully consider both climate and land-use change when projecting biodiversity impacts. We show that biodiversity is likely to suffer severely if bioenergy cropland expansion remains a major component of climate change mitigation strategies. Our study calls for an immediate and significant reduction in energy consumption for the benefit of both biodiversity and to achieve the goals of the Paris Agreement.
