Optimization Strategies for Agricultural Non-Point Source Reduction

Abstract:

A methodological framework is brought forward, with the aim of reducing the agricultural non-point source (ANPS) pollution from the overuse of fertilizers and pesticides in rural area of the lake Dianchi watershed. In order to build a bridge connecting the public and the authority, a simplified decision support tool is conceived to realize the management target. Firstly, a rapid calculation method for the agricultural non-point source pollution is given called factor - coefficient method. Multiple kinds of agricultural non-point loads are calculated from both the pollution factors and the pollution coefficients. The sources include the farmland runoff, rural life, livestock and poultry, and so on. Then a checklist of engineering and management strategies to reduce ANPS are listed. Finally, according to the specific flowchart, the Best Management Practices (BMPs) to control the agricultural non-point source pollution of Lake Dianchi would be built, adapting with the real conditions of the watershed.
