Fresh water resources are at the same time ecological, economic, social, and cultural goods and must be managed accordingly. However, efforts to manage these resources are complicated by tensions arising from possible clashes between the regimes favouring privatization, trade and investmentliberalization, and domestic and international regimes governing water resources, environmental protection and human rights. The relationships between the international economic and legal framework on the one hand and fresh water resource management and protection on the other, are complex andmultifaceted. This book addresses the key interdisciplinary issues that increasingly confront policy makers, tribunals, arbitration bodies and other institutions. It focuses primarily on law, but also includes perspectives from economics, political science and other disciplines. It examines such questions asare governments free to decide whether or not to export water resources? Can foreign investors sue host states for adopting measures to control water pollution? Can international trade rules be used to reduce or eliminate water related subsidies? Do rules on the liberalization of water servicesaffect domestic and international human rights obligations relating to water supply? More generally, how do the procedural rights of states, individuals, affected communities and investors affect decisions regarding the right to drinking water, the rights of investors to exploit water resources, andthe rights of governments to protect their lakes, rivers and groundwater?
