Future Emission Scenario Effects on Melon Cultivars (Cucumis melo L.) in the Brazilian Semi-Arid Region

Future emission scenarios can interfere with the yield of major crops. In this study, we investigated future impact increased air temperature and relative humidity on melon phenology water demand in Brazilian semi-arid region. We applied PRECIS (Providing Regional Climates for Impact Studies) climatological model to develop Intergovernmental Panel Climate Change scenarios—B2 optimistic scenario A2 pessimistic scenario—and assessed climate change effects two cultivars. The “Orange County” hybrid, Honeydew melon, grew from 2006–2007, “Néctar” Galia 2008. These cultivars were also considered using actual scenario. found that B2 will cause a cycle decrease 15.49 25.35% hybrid 9.84 18.03% hybrid. changes increase crop coefficient daily rate evapotranspiration. Regarding shortening overcomes increases, decreasing by 13.7–18.3%. be proportional demand. more sensitive increases than melon.
