O presente trabalho teve como objetivo estimar as demandas futuras de água para irrigação em quatro culturas nesta bacia (feijão, milho, trigo e soja), comparando com um cenário atual. Regiões que possuem sua economia voltada para a agricultura, como na bacia hidrográfica do rio Ijuí, são frequentemente afetadas por períodos de estiagem ou de excesso de chuva que prejudicam a produtividade agrícola.
In the short term (2011-2040), water demands were similar to those for the baseline period, but from the middle of the century onwards (2041-2100), greater reductions were observed.Ī alteração de temperatura e da intensidade e frequência dos índices pluviométricos tem influenciado a demanda de água para irrigação. The results showed that, in the future, irrigation water requirements will be smaller for all crops. The one-dimensional SWAP model was used to estimate the water demand for irrigation. Meteorological data forecasts were obtained from the regional climate model ETA 40 CTRL for the climatic scenario A1B, for the baseline (1961-1990) and future (2011-2100) periods. This study aimed to evaluate future irrigation water demands of four crops in this basin (bean, corn, wheat and soybean), comparing them with a baseline period. Regions that have agriculture-based economies, as in the Ijuí River basin, are often affected by periods of drought or excessive rainfall, which is harmful for agricultural productivity.
