However, at the same time, it has a damaging effect onwater availability and mayworsen episodes of micro regional water scarcity. In this paper, we analyze scenarios of irrigation expansion in the Brazilian agriculture, using a computable general equilibrium model (the TERM-BR model) to assess the impacts on water demand for 2025. Simulations were carried out for areas deemed potentially suitable for irrigation based on National Water Resources Plan (PNRH) and Ministry of National Integration report (MI).We increase the regional detail to focus on some of the Brazilian Northeastern States, in order to assess the balance between regional water supply (as determined by the Climatic Water Balance) and demand. The comparative results of the ClimaticWater Balance and the TERM-BR model for the region point to potential water availability problems in specific states, such as Alagoas and Pernambuco.  aAgriculture  aClimate  aWater balance  aClima  aAgricultura irrigada1 aFERREIRA FILHO, J.
