Analyzing Water Scarcity in Global CGE Models

08 Sep 2017 | Contributor(s): Jing Liu, Tom Hertel, Farzad Taheripour

Incorporating water into a computable general equilibrium (CGE) model operating at global scale can be extremely demanding due to the absence of standardized data, the sheer dimensions caused by intersecting river basins with countries, and difficulties to model demand for and supply of water....

Predicting Long Term Food Demand, Cropland Use and Prices
