An Integrated Approach to Climate Change Impact Assessment on Basin Hydrology and Agriculture

Climate change, including changes in air temperature and precipitation, would affect the basin hydrological regime, and the change in the hydrological system might have some impacts on agriculture. To assess the impacts of climate change on the hydrology and agriculture of a basin, the relationship between climate and basin hydrology, and between hydrology and the agriculture of the basin need to be analysed systemically and integrally. In this study, an integrated approach to these analyses or diagnoses is developed for a better projection and evaluation of the climate change impacts as the foundation for better adaptation. It takes into account various complicated factors in these relationships, which are often uncertain and affect each other and must therefore be treated in a particular way.
