Multi-Level Prioritization Analysis of Water Governance Components to Improve Agricultural Water-Saving Policy: A Case Study from Korea

The challenge of unstainable agricultural water usage in Korea has continued interminably despite persisting climate change impacts; thus, necessitating urgent actions to forestall future water crises. However, achieving this goal requires the involvement of stakeholders to develop an effective governance policy concerning water saving. This study investigates the components of water governance following existing water policy gaps. A multi-level Delphi-AHP technique was used to identify and prioritize the essential components of agricultural water governance that can specifically enhance water-saving policy in Korea. The analysis of twenty-nine formulated components (six main and twenty-three sub-components) based on the OECD water policy gaps was conducted. A Delphi-AHP technique with process evaluation of the agricultural water experts’ opinions under pairwise comparisons was used to arrive at the relative order of importance of the components. The order of main components based on the consolidated weight follows core actors (0.316), law, policies, and systems (0.069), budget support (0.135), information sharing and communication (0.099), mutual learning (0.142), and external experts (0.239), while village representatives (0.353), legislation (0.358), central government (0.311), policy committee (0.309), education course (0.374), and facilitator (0.402) were considered as priorities, respectively, for the sub-components of water governance. The findings indicate that strengthening the informal institution could address the water governance gaps in the agricultural sector to achieve water-saving policies. This study recommends a bottom-up approach to water governance that could promote the active participation of core actors such as farmers and villagers in the design of policy and management of agricultural water resources.
