Conteúdo: | Climate change is conceptually referred to as a modification to the average of climate variables and their natural variability, due to both natural and anthropogenic driving forces, such as greenhouse gas emissions. Climate change potentially impacts rainfall, temperature, and air humidity, which have relationship with plant evapotranspiration and consequently to irrigation water needs (IWN). The purpose of this research is to assess climate change impacts on irrigation water demand, based on climatic impacts stemming from future greenhouse gas emission scenarios. The study area includes eight municipalities in the Jaguaribe River Basin, located in the Ceará State of semiarid northeast Brazil. The FAO Penman-Monteith method is used for the calculation of a reference evapotranspiration with limited climatic data. IWN projections are calculated using bias-corrected climate projections for monthly rainfall and surface temperature derived from the United Kingdom?s Hadley Centre Regional Climate Model simulations. The increase in the average IWN is projected to be 7.9 and 9.1% over the period 2025-2055 for the A2 and B2 scenarios, respectively with respect to 1961-1990 baseline.
