Enhancing Sustainability in Rice Farming: Institutional Responses to Floods and Droughts in Pump-Based Irrigation Systems in Wajo District, Indonesia

Climate change-induced floods and droughts pose significant threats to rice farm development in Indonesia, particularly in regions reliant on pump-based irrigation systems. The urgency of this study lies in the increasing vulnerability of rice production to extreme weather events, necessitating institutional adaptations to enhance irrigation sustainability and financial risk sharing. This study examines the role of irrigation institutions in supporting sustainable rice farming in Wajo District, Indonesia. Using a case study approach, qualitative data were collected from four irrigation service provider (ISP) units across three subdistricts through in-depth interviews and focus group discussions. The analysis focuses on institutional mechanisms, including irrigation payment structures, input credit systems, and cost-sharing arrangements. The findings reveal that institutional frameworks are crucial in mitigating financial risks by promoting adaptive payment schemes and equitable cost-sharing mechanisms. Farmers’ access to critical agricultural inputs, such as fertilizers and pesticides, is enhanced through collaborative financing models, ensuring resilience against climate-induced production risks. However, variations in institutional support led to disparities in irrigation fees, credit access, and financial sustainability across study sites. This study underscores the need for risk-based irrigation pricing models and public–private partnerships to invest in climate-resilient infrastructure, such as water storage facilities and sustainable irrigation systems. In conclusion, it is important to remember that each of us, including agricultural policymakers, researchers, and stakeholders, plays a crucial role in implementing these solutions. By strengthening institutional governance, promoting flexible financial mechanisms, and integrating climate-adaptive pricing models, we can all contribute to enhancing the long-term sustainability of rice farming in Indonesia.
