Using our estimates, our simulations show that, ceteris paribus, French farmers would increase pesticide use by +7% to +15% by 2050 under the RCP4.5 climate change scenario. 📈🌱 #PesticideProjection

Pesticide use is more sensitive to weather in the case of those with higher risks 📈 to human health in the case of herbicides and fungicides and for those with higher risks to the environment in the case of insecticides.

New paper: what are the impacts of a public policy aiming to halve mineral nitrogen use in EU agri? We show that the climate and biodiversity associated benefits more than offset the decrease in agri benefits. @prudhommeremi
