Abstract :
Climate change impacts on food production have become an interesting topic to most agricultural researchers. This paper mainly discusses the rainfed maize water use indices in the subareas of Loess Plateau under the A2 and B2 future climate scenarios with SWAGMAN® Destiny model. The result shows that evapotranspiration will increase in future under both scenarios while the water use indices will decrease for rainfed maize production in the whole Loess Plateau. Although the study indices mentioned in this paper have the same tendency under both scenarios, the variability under the A2 scenario is higher than that under the B2 scenario.
