| Summary: | [EN] Analyzing modernization of traditional irrigated areas in western Argentina. The Tulum Valley, in San Juan, is one of the largest traditional irrigated areas in western Argentina. Of pre-hispanic origin in the XII century this oasis holds a population of some 600,000 people, concentrating 90 % of the province’s total. Its 120,000 ha of irrigation concessions have shaped a complex agro-ecosystem where irrigation still accounts for more than 90 % of water allocations based on seniority rights; inherent to the land, irrevocable and perpetually granted. In this conservative context, modernization of irrigation have been focused either at large hydraulic infrastructure, i.e. dams and main canals, in one end, or at farm level, in the other. For several reasons, Collective Action for communal management of water has become marginal and both institutional and technological changes have lagged behind. Under this situation, this work studies one administration unit (Irrigation Commission) in the Pocito County made up mainly of small and diversified progressive farmers who share the Calle 9 canal that irrigates 741 ha. With a GIS as a support tool, all Productive Units have been surveyed and crop´s water needs contrasted to water supply by the irrigation network, relating water balance to irrigation strategies at both farm and collective level. This first analysis of water management as a Common Pool Resource (CPR) gives insight to modernization scenarios compatible with already institutionalized practices. |
