Abstract: Agriculture is a cornerstone of the achievement of the United Nations Sustainable Development Goals, yet agricultural non-point source pollution presents significant challenges to regional water, food, and ecological security. Therefore, there is an urgent need to coordinate the integration strategy of water resources, water environment, and water ecology (termed “three-water”), which is critical for promoting sustainable and high-quality regional development. Current management of agricultural non-point source pollution faces several key challenges: high water consumption with low recycling rates, complex pollutant compositions with variable production and transport processes, lack of coordination between water quality improvement and ecological health, and unclear responsibilities leading to difficulties in long-term project maintenance. To address these challenges, the research team proposes a series of recommendations for establishing a coordinated management system for agricultural non-point source pollution. These include establishing regional circulation wetlands in farmlands to create recycling systems for water, fertilizer, and pesticide resources; utilizing irrigation and drainage engineering systems to intercept and purify non-point source pollutants in a stepwise manner; integrating the comprehensive use of water and fertilizer in crop and livestock farming to achieve precise control and efficient resource use; building a co-governance platform to develop technical standards and management paradigms. These strategies aim to enhance agricultural water use efficiency and reduce non-point source pollution, ensuring the sustainable development of agriculture.
