Crop-specific exposure to extreme temperature and moisture for the globe for the last half century

چکیده
Abstract Global assessments of climate extremes typically do not account for the unique characteristics individual crops. A consistent definition exposure specific crops to extreme weather would enable agriculturally-relevant hazard quantification. To this end, we develop a database both temperature and moisture facing by explicitly accounting crop characteristics. this, collate crop-specific parameters from agronomy literature, which are then combined with time-varying locations high-resolution information quantify weather. Specifically, estimate shocks during growing season 0.25 ? spatial grid daily time scale 1961 2014 globally. We call Agriculturally-Relevant Exposure Shocks (ARES) model make all ARES output available paper. Our approach leads smaller average value rate extent than does crop-agnostic approach. Of 17 included in study, 13 had an increase heat, while 9 were more exposed cold over past half century. All study show statistically significant wetness dryness. Cassava, sunflowers, soybeans, oats greatest hot, cold, dry, wet exposure, respectively. compare results EM-DAT disaster database. highlight importance defining agriculture.
