Comparison of sustainability issues in two sensitive areas of China

After 30 years of economic reform since opening to the outside world in 1978, China's Gross Domestic Product (GDP) has increased by 150% over the past 15 years. The sustainability of such intense economic activity has been questioned from the perspectives of the social, environmental, and economic dimensions of sustainability. In this study, we assessed the spatial and temporal trends in sustainable development in two sensitive agricultural areas of China: Dezhou district, a well-developed region, and Guyuan district, an underdeveloped region. We used the pressure-state-response (PSR) model and a participatory approach that involved local experts to select and evaluate 27 area-specific indicators, then calculated changes in their values from 1985 to 2002. We aggregated these indicators into dimension- and PSR-specific indices to assess the sustainability of development in both regions. There two regions differed greatly in sustainability, but the current status of sustainable development raises concerns in both areas, especially from the perspective of balancing the three dimensions of sustainability. In 2002, Dezhou district performed well economically, with an index value of 0.78 (where 1.0 = sustainable), followed by environmental and social sustainability (both with index values of 0.48). All three indices have increased since 1985 (by 0.17, 0.25, and 0.13, respectively). In Guyuan district, environmental sustainability was highest (with an index value of 0.73), followed by economic and social sustainability (values of 0.55 and 0.37, respectively), but economic sustainability has decreased by 0.04 since 1985, whereas environmental and social sustainability increased by 0.18 and 0.12, respectively. To promote sustainable regional development, development priorities should be determined by considering both the regional and temporal variation in the three sustainability indices.
