Increased soil erosion on sloped land has become a significant environmental concern in China that has been attributed to human activities such as deforestation, over-cultivation, and over-grazing of livestock. In order to reduce soil erosion on sloped lands, the Chinese government has responded by implementing large-scale, ecological rehabilitation programs, including the "Grain for Green" reforestation project. This program involves financial incentives to transition farmers into other economic activities with the goal of reducing ecological pressures and degradation. Because of the scope and potential impacts from these programs, detailed research is needed to understand their social and ecological effects. This paper reports on research conducted in Tianquan County, Sichuan Province, and Wuqi County, Shaanxi Province, that evaluates the effects of the program upon local economies and household livelihood systems. The paper argues that the successful conversion of farmland under "Grain for Green" depends upon local government involvement, local economic development, and funding for local projects. Without economic development within rural economies, we conclude that farmers will remain dependent upon continued subsidy assistance to meet the policy's ambitious environmental restrictions, thereby undermining the program's long-term sustainability.
中国坡地土壤侵蚀加剧,这已成为一个重大的环境问题,其主要归因于人类活动,如毁林、过度耕种和过度放牧牲畜。为了减少坡地土壤侵蚀,中国政府通过实施大规模的生态恢复计划做出了回应,其中包括“退耕还林”造林项目。该项目涉及经济激励措施,鼓励农民转变为其他经济活动,以减轻生态压力和退化。由于这些项目的范围和潜在影响,需要进行详细的研究,以了解其社会和生态影响。本文报告了在四川省天全县和陕西省吴起县进行的研究,评估了该项目对当地经济和家庭生计系统的影响。本文认为,“退耕还林”工程中耕地的成功转换取决于地方政府的参与、当地经济发展和地方项目资金。如果农村经济没有经济发展,我们得出的结论是,农民将仍然依赖于持续的补贴援助来满足政策的雄心勃勃的环境限制,从而破坏该计划的长期可持续性。
