Water and Ecological Security at the Heart of China’s Silk Road Economic Belt
Many countries along the Silk Road economic belt are in the arid climate zone, which are typically rich in natural resources but very fragile in their ecological environment. This chapter presents the recent research progress on regional water security and ecosystem stability in Central Asia, the heart of the Silk Road economic belt. Due to climate changes, the solid-state water resources (i.e., glacier and snow) have retreated, leading to an overall decrease of solid water storage and a higher uncertainty of water system. Additionally, because of climate changes and anthropogenic activities (e.g. unplanned over-expansion of agricultural area), this region is facing various eco-environmental problems such as intensified drought and deterioration of ecological systems. Future water resources and possible ecological responses deserve further studies in order to provide a healthy ecological environment for building the Silk Road.
