Prestudy on River Environmental Improvement Based on Human Water Harmony: PEST Analysis of Flood Control Situation in Mainland China

抄録

River environment improvement activities have commonly been unfolded in Japan during its nature-oriented river management for decades. To evaluate their prospects in mainland China, grasping the current situation of flood control should always be the first place. We achieved by a comprehensive overview survey based on past detailed data and research findings of related domains, within the framework of Political, Economic, Social and Technological dimensions (PEST Analysis). Our results showed that evolutionary progression had continued obviously in every dimension during the period of 2004 to 2013. However, flood control expenditure’s proportion to the whole water conservancy investment showed a downward trend despite both amounts kept increasing, since a focus shifting to water resource projects. It suggests that not until accomplishing those water resources projects in next dozen years will the river environment improvement activities be virtually promoted under the conception of human water harmony.
