摘要: Water is increasingly becoming a limiting factor for sustainable economic growth and development in many countries. Its allocation has significant impacts on overall efficiency, particularly with growing physical scarcity certain regions. Greater water supply variability further increases vulnerability affected also become strategic resource involving conflicts among those who may be differently by various policies. This paper analyzes policy interventions aimed at improving decisions, using novel approach that incorporates macro micro level considerations unified analytical framework. The framework facilitates assessment of linkages policies their within individual sectors economy-wide. Drawing country based studies Morocco, South Africa, Turkey, Mexico, the analysis reveals difficult tradeoffs objectives, including priorities placed different sectors, regional advantages, general efficiency gains versus broader social impacts. comparison demonstrates usefulness information makers can use to rank according emphasis objectives. compares approaches used other apply computable equilibrium models contexts water, environment agriculture.
