Global climate change exacerbates water scarcity, making efficient water use a critical priority worldwide. In T & uuml;rkiye, agricultural irrigation accounts for a significant share of water consumption, underscoring the need for sustainable management practices. Water users associations (WUAs) play a crucial role in overseeing irrigation schemes and optimizing water use in agriculture. This study assesses the irrigation performance of the Karacabey Water Users Association in Bursa Province using data from 2006 to 2023. Seven key irrigation performance indicators were analyzed, revealing an average irrigation ratio (IR) of 69.02%, irrigation water distributed per unit area (WIRR) of 8602.04 m3 ha-1, and a water supply ratio (RWS) of 1.33. The operation and maintenance cost (WOM) per unit irrigation water was calculated as USD 0.02 m-3, while total management, operation, and maintenance costs amounted to USD 0.08 m-3. The production value (WP) per unit irrigation water was found to be 0.89. Correlation and regression analyses indicated that WIRR is significantly influenced by indicators related to production, management, and water consumption. The findings highlight the necessity of a comprehensive approach to improving WUA performance, considering multiple performance indicators. To ensure sustainable agricultural water use, adopting advanced irrigation techniques, modernizing infrastructure, and enhancing management strategies are essential. This study provides valuable insights into enhancing irrigation efficiency and sustainability.
