Zoning management for agricultural non-point source pollution: a national-scale perspective in China

Abstract

Agricultural non-point source pollution (ANPSP) poses significant challenges to global water security and ecosystem health. This study proposes a zoning management framework for ANPSP in China, integrating ecological sensitivity, pollution load intensity, and agricultural production structures. Seven distinct governance zones are delineated, each with tailored strategies and measures. Supported by technological innovation, policy incentives, and participatory governance, this framework aims to achieve precise pollution control and water quality improvement.

Keywords

Agricultural non-point source pollution / zoning management / integrated governance / precision control
