Abstract:
      This paper introduced the basic situation, main practices, achievements and enlightenment of the World Bank Loaned Guangdong Agricultural Pollution Control Project, and summarized the governance mode and experience of the project. The results showed that the project created the management modes and technology extension methods. The pesticide and chemical fertilizer consumption of the project farmers decreased by 30.9% and 30.6% respectively compared with those before the project, and 19.9% and 22.1% less than those of the non-project farmers. From 2014 to 2019, 17 000 tons of chemical fertilizer(converted into purification) and 813 tons of pesticides(active ingredients) were reduced by the project accumulatively. The average reduction rates of total nitrogen and total phosphorus were 26.3% and 36%, respectively.The yield of rice per mu increased by 18.9%. 99.3% of the farmers could consciously return the pesticide packaging waste to the designated collection points. The water quality and soil health of farmland were improved and the biological population increased. Both the comprehensive utilization rate of wastewater and facilities and equipment matching rate of the projects farm reached 100%. The removal rates of chemical oxygen demand(COD), ammonia nitrogen and phosphorus were 98.68%, 95.61% and 96.89%, respectively. According to the calculation of the designed inventory, in the first half of 2020, the emission reduction capacity of COD, ammonia nitrogen, biological oxygen demand(BOD) and total phosphorus(TP) in breeding industry was 43 871 tons, 2 966 tons, 15 639 tons and 708 tons, respectively. According to the actual inventory,the emission reduction capacity of COD, ammonia nitrogen, BOD and TP was 15 675 tons, 961 tons, 5 263 tons, and 220 tons, respectively. It has accelerated the green development of agriculture and the sustainable development of agriculture in Guangdong Province.
