Résumé
California’s San Joaquin Valley is one of the world’s most vital and productive farming areas.However, due to topographic, environmental and political constraints much of this highlyproductive region is threatened by drought, saline groundwater and drainage disposal. In 1984State and Federal government agencies established San Joaquin Valley Drainage Program(SJVDP) to investigate drainage related problems and to develop possible solutions. Therecommendations of SJVDP included : i) source control ; ii) drainage reuse ; iii) evaporation ponds ;iv) land retirement ; v) groundwater management ; and vi) discharge to the San Joaquin River. Thepurpose of this research was to investigate how SJVDP works at institutional and farm levels, inorder to draw lessons to other arid areas, in particular to Khorezm region in Lower Amu Darya,Uzbekistan. Past and current water management strategies were examined in both case areas,consequently it assessed whether these strategies enhance or constrain sustainable irrigatedagriculture. To analyze and discuss of research used consequently the water management development paradigms and three dimensions of sustainability of Allan, it is consisting of social,economic and environmental – and the central mediating role of discursive hydro-politics. Despite that both cases are not same in social-economic, political and cultural context still lessons from California can be learned for Uzbekistan. Although, the water management system in California isstill heading towards sustainability, it still serves as a good example for Uzbekistan to face andcope with current and future water management issues and possible lessons are learned. Long term experiences with its mistakes as well as successes in drainage management are learned to Uzbekistan’s case. Although, it should be kept in mind that the policies and strategies cannot be directly applied but rather should be translated taking into account the existing social, technical, economic, and political dimensions.
