Abstract: | The Great Western Development Strategy (GWDS) is a long term national campaign aimed at boosting development of the western
area of China and narrowing the economic gap between the western and the eastern parts of China. The Strategic Environmental
Assessment (SEA) procedure was employed to assess the environmental challenges brought about by the western development plans.
These plans include five key developmental domains (KDDs): water resource exploitation and use, land utilization, energy generation,
tourism development, and ecological restoration and conservation. A combination of methods involving matrix assessment, incorporation
of expert judgment and trend analysis was employed to analyze and predict the environmental impacts upon eight selected environmental
indicators: water resource availability, soil erosion, soil salinization, forest destruction, land desertification, biological
diversity, water quality and air quality. Based on the overall results of the assessment, countermeasures for environmental
challenges that emerged were raised as key recommendations to ensure ecological security during the implementation of the
GWDS. This paper is intended to introduce a consensus-based process for evaluating the complex, long term pressures on the
ecological security of large areas, such as western China, that focuses on the use of combined methods applied at the strategic
level. |
