Desertification has inflicted severe damage on the natural environment and social economy for decades, particularly in the arid and semi-arid regions of northern China. In Yanchi County, a series of projects were implemented to combat desertification after 2000. To assess the effects of these Desertification Control Projects from the farmers' perspective, we divided Yanchi County into two regions (the northern and southern regions) according to their different environmental conditions. We collected data including basic family information, farmers' perceptions and attitudes, and farmers' suggestions, in a questionnaire investigation following the Participatory Rural Appraisal approach. Data analysis using the Mann-Whitney U test and Fisher's exact test revealed that the Desertification Control Projects were generally successful, as the local environment and farmers' incomes were both improved. Farmers were all satisfied with the effects of the projects, but the farmers in the southern region had a higher acceptance of the projects than those in the northern region. In addition, three problems with the Desertification Control Projects were noted: the farmers had a low degree of participation in the projects, the farmer's low incomes affected the sustainability of the projects, and the implementation of the complete grazing ban had several adverse effects. We provided suggestions for solving these problems. Our findings have important implications for assessing the effects of environmental conservation projects, especially from a participant's perspective.
荒漠化问题已持续数十年,对自然环境和社会经济造成严重破坏,尤以中国北方干旱半干旱地区为甚。2000 年以来,盐池县实施了一系列防沙治沙工程。为了从农户视角评估这些防沙治沙工程的效果,我们根据不同的环境条件将盐池县分为南北两个区域。我们采用参与式农村评估方法,通过问卷调查收集了包括基本家庭信息、农户认知和态度以及农户建议等数据。使用曼-惠特尼 U 检验和 Fisher 确切检验进行数据分析的结果表明,防沙治沙工程总体上是成功的,当地环境和农民收入都得到了改善。农户对项目效果均表示满意,但南部地区农户对项目的接受程度高于北部地区。此外,防沙治沙工程还存在三个问题:农户参与度低、农户收入低影响项目的可持续性以及全面禁牧的实施产生了一些负面影响。我们针对这些问题提出了解决建议。本研究结果对评估环境保护项目的效果具有重要意义,特别是从参与者的角度。
