Ecological restoration, social-economic changes and sustainable development in the Three Gorges Reservoir area: A case study in Yunyang, Chongqing Municipality.

The Three Gorges Reservoir area contains high mountains and deep valleys. The fragile mountainous ecosystems are facing problems such as overpopulation, less available farmland, ecological degradation and poverty. The construction of the Three Gorges Project and a series of ecological restoration activities and social-economic changes have influenced the present and future viability of this area. The measures which have been taken indicate that restoring and renewing the degraded ecosystems and improving the economy is a prerequisite and is possible. Yunyang, a typical county, both in terms of poverty and ecological degradation in the Three Gorges Reservoir area of Chongqing Municipality, was chosen for the case study. This paper discusses the impacts of the Grain-for-Green project, ecological agriculture, urban and infrastructure building and ecological immigrants on the regional sustainable development through detailed field investigation and a questionnaire survey.
