"The expansion of irrigated agriculture in brazil and potential regional constraints "
by dos Santos Fachinelli Ferrarini, Angel, Joaquim Bento de Souza Ferreira Filho, Santiago Vianna Cuadra and Daniel De Castro Victoria

Regional expansion of irrigated agriculture causes a growth in foodstuff production in the country, minimizes risks for the farmer and strengthens foodstuff security for future generations. However, at the same time, it has a damaging effect on water availability, via demands for water use, which may intensify situations of microregional water scarcity . The TERM-BR was used in order to simulate expansion scenarios in irrigated areas, aiming at verifying the impact of such an expansion in the use of water for 2025. Scenarios were adapted for the National Plan for Water Resources (PNRH) and simulations were carried out for areas deemed potentially suitable for irrigation based on the MI study (2014). Irrigated agriculture was separated from dry farming in terms of differential productivity. The Climate Water Balance (CWB) was estimated for Northeastern States in order to compare regional water supply and demand. Results for the simulation suggest that the greater impact on the GDP, investment and use of regional families would take place in the state of Mato Grosso, in the Midwest region of the country. The comparative result of the CWB and the TERM-BR simulation for states in the Northeastern region point to potential hydric problems in the states of Alagoas and Pernambuco in particular.
