The GTAP-W model: accounting for water use in agriculture
Alvaro Calzadilla, Katrin Rehdanz and Richard S.J. Tol
Abstract: Water and agriculture are intrinsically linked. Water is
essential for crop production and agriculture is the largest consumer of
freshwater resources. However, this link is commonly ignored by economic
models mainly because water use is not reported in the national economic
accounts. Few regions have markets for water. This paper describes the new
version of GTAP-W, a multi-region, multi-sector computable general
equilibrium model of the world economy. The new version of GTAP-W
distinguishes between rainfed and irrigated agriculture and introduces
water as an explicit factor of production for irrigated agriculture.
Moreover, the new production structure accounts for substitution
possibilities between irrigation and other primary factors. The new model
has been used to study a variety of topics including: irrigation
efficiency, sustainable water use, climate change and trade liberalization.
This paper is a technical description of the data and features added to the
standard GTAP model
