"Developing a SAM/CGE Framework for Water Quality Assessment Using Satellite Accounts"
by Osman, Rehab, Emanuele Ferrari and Scott McDonald


Abstract
This study provides quantitative assessments for the impacts of crop yields enhancement associated with changes in water quality and soil fertility. It employs a single country CGE (STAGE) model calibrated to an extended version of a recently constructed SAM for Egypt 2008/09. The main contribution of this study is incorporating satellite accounts for water quality indicators into the SAM/CGE framework. The SAM segments the agricultural accounts by season and by irrigation scheme; Nile water- and groundwater-dependent as well as rain-fed agricultural activities. The simulations report strong positive economy-wide impacts, which imply that the planned investments in water quality improvements are worthwhile even with very low generated crop yields. Furthermore, the results show that, without increasing irrigation water requirements, Egypt can achieve outstanding expansions in rice output and exports. This highlights the importance of by investing in improving irrigation water quality for the overall economy.
