The urgent need to reduce agricultural water consumption and tackle water scarcity has made developing water-saving technologies in agriculture a top priority. However, However, introducing these technologies does not automatically guarantee a reduction in overall water consumption within the sector. The rebound effect plays a significant role in limiting the effectiveness of water conservation policies. A comprehensive understanding of irrigation's water rebound effect (WRE) is essential for successfully conserving agricultural water resources, especially in arid regions. This study focuses on Xinjiang and empirically analyzes the rebound effect following the implementation of water-saving measures. This study focuses on Xinjiang and empirically analyzes the rebound effect following the implementation of water-saving measures. The findings indicate that from 2001 to 2020, water consumption remained a concern despite advancements in irrigation technology, leading to a 40.86 % reduction in the irrigation quota (a decrease of 5567.12 m³/ha). The cultivated land area, irrigation area, water-saving irrigation area, agricultural output value, agricultural water consumption, and agricultural water use productivity in Xinjiang have increased by 2.86 × 10 6 ha, 1.40 × 10 6 ha, 1.70 × 10 6 ha, 81.61 × 10 9 CNY, 6.28 × 10 9 m 3 and 1.57 CNY/m 3 , respectively, with growth rates of 83.54 %, 41.27 %, 134.24 %, 217.87, 7.80 % and 192.83 %, respectively. Despite the reduced water allocatio...
