This study investigates the likely regional impact of global changes in water availability on crop production, international trade of agricultural commodities, and overall economic production by 2030. The study compares the results of different regional and sectoral aggregations of ENISAGE model (van der Mensbrugghe, 2008) to different regional and sectoral aggregations of GTAP-BIO-W model (Liu et al., 2014). We employ the core structure of GTAP-Water Database by Haqiqi et al. (2016). The Data Base and models are modified to minimize the discrepancy.
