Chapter 2: Policy Setting for Sustainable Water Management: GATS Rules and Water Management Systems
Gérard Mondello 2.1 INTRODUCTION Nowadays, scientists recognise that fresh water resources are being exhausted, polluted, and overexploited.1 However, and maybe paradoxically, in physical terms, the same quantity of water is being exchanged, following a natural cycle of evaporation and precipitation. Human activities and water policies have heavily impacted on the regularity of this natural cycle and, as a consequence, on the quality and the quantity of water available for human use. To ensure the sustainability and efficiency of water use in the future, a programme of Integrated Water Resource Management (IWRM)2 should be implemented without delay. IWRM recognises two important, but potentially conflicting, aims. The first one is based essentially on the ethical and moral ideal of providing free and fair access to water resources for every human being. The second aim recognises that IWRM must follow sound economic practices. Recent studies of water management have concluded that the quantity and quality of water must be dealt with in an integrated way, for example, it must consider how efficient allocation and distribution can also be made equitable (see, for instance, Spulber and Sabbaghi, 1997; Shirley, 2002). However, when faced with the harsh realities and complexities of this much debated subject, it quickly becomes apparent that it is far simpler to write about IWRM than to successfully implement it in the real world. Whatever the level of economic development in a country, the management of the water system raises the same basic questions. These are: what should be the...
