บทคัดย่อ

This research aimed to (1) study the approaches to common–pool resource management in the lower northern irrigation area under the Wang Yang–Nong Khwan Water Delivery and Maintenance Project, (2) investigate the problems and obstacles in managing these shared resources, and (3) propose sustainable development strategies for resource management in this irrigation area.

            The study found that community–based resource management exhibited three main characteristics: (1) institutional management, (2) utilitarian management, and (3) supportive eco–cultural management. These were observed across four water user groups, following Elinor Ostrom’s framework for common–pool resource management. Eight key conditions were identified as critical for effective community resource management: clearly defined boundaries; consistency of rules and regulations; inclusive participation in decision–making; monitoring and enforcement; sanctions for violations; effective conflict resolution mechanisms; state recognition of community management rights; and linking resources to larger systems through network partnerships. Challenges faced by the Royal Irrigation Department in managing agricultural water in this area included personnel shortages, increasing water use by farmers outside the irrigation system leading to insufficient water supply, and lack of budgetary and knowledge support for rice farmers from relevant agencies. To achieve sustainable water management, the study recommends an integrated management approach. This includes establishing memoranda of understanding for shared water use among upstream, midstream, and downstream areas, involving all four water user groups and the Royal Irrigation Department. This collaborative approach aims to sustainably address water scarcity and support the local population within the project’s jurisdiction.
