Resumen
Agricultural non-point source pollution is intricately connected to the rural population?s production and lifestyle. The heterogeneous composition of livelihood capital results in varied livelihood types, influencing the farmers? attitudes and perceptions of the treatment projects. This ultimately causes discrepancies in the farmers? evaluation of agricultural non-point source pollution control. In this study, a participatory evaluation method was employed to evaluate the performance of agricultural non-point source pollution control projects in the Yilong Lake Watershed of Yunnan Province and analyze the underlying reasons for the differing performance evaluations. The findings revealed that pure farmers? performance evaluation value for agricultural non-point source pollution control projects in Yilong Lake Basin was 0.4811 (with the full mark being 1), with a general evaluation grade. Part-time business households had a performance evaluation value of 0.5969, also with a general evaluation grade, while non-farmers had a performance evaluation value of 0.7057, with a good evaluation grade. The performance evaluation value ranked from highest to lowest is non-farmer > part-time farmer > pure farmer. The main factor affecting the variation in farmers? performance evaluation is the key index of different livelihood capital. If pollution control projects can promote the adjustment of farmers? livelihood capital types, it can enhance not only the performance evaluation degree of farmers, but also the sustainability of farmers? livelihoods and increase their adaptability to livelihood risks. Therefore, pollution control projects should consider farmers? livelihood capital types and be implemented accurately to improve farmers? satisfaction and sustainability.
