RELATIONSHIP BETWEEN AGRICULTURAL LAND SYSTEMS AND WATER USE DURING THE APPLICATION OF PARTICIPATORY IRRIGATION MANAGEMENT

Abstract

The identification of water rights is essential to the application of Participatory Irrigation Management (PIM) policies. Water and agricultural land have traditionally had strong relationships. We must clarify land tenure conditions and their relationships with water rights. This paper presents the results of studies focused on the relationships between agricultural land systems and water use in several African and Asian countries. It describes different situations related to land systems and water use, as well as the relationships between them. In study areas, in addition to historical backgrounds, land tenure may be associated with the extent to which state, customary, and individual involvements affect farmers’ de facto water rights. In general, water rights are clearly established in developed countries because formal administration of land and water resources has been functional and well-established. In developing countries, further institutional arrangements may be required to enable farmers to maintain water rights and increase efficient water use and management. However, no single solution is available. This paper describes how local contexts may vary with respect to land and water tenure. When PIM is introduced into irrigation schemes, it must be carefully integrated into agricultural land systems and the regulation of water rights in target areas. First, a land management system must be developed that secures farmers’ rights to ensure rational/optimal use of irrigation water. This offers important implications for rice irrigation and other crops that requires relatively intense and long-term investments in land development and advanced water management.
