In ecologically fragile areas with arid climate, such as the Heihe River Basin in northwestern China, sustainable social and economic development depends largely on the availability and sustainable uses of water resource. However, there is more and more serious water resource shortage and decrease of water productivity in Heihe River Basin under the influence of climate change and human activities. This paper attempts to identify the severe water scarcity under climate change and presents possible solutions for sustainable development in Heihe River Basin. Three problems that intervened land use changes, water resource, the relevant policies and institutions in Heihe River basin were identified, including (1) water scarcity along with serious contradiction between water supply and demand, (2) irrational water consumption structure along with low efficiency, and (3) deficient systems and institutions of water resource management along with unreasonable water allocation scheme. In this sense, we focused on reviewing the state of knowledge, institutions, and successful practices to cope with water scarcity at a regional extent. Possible solutions for dealing with water scarcity are explored and presented from three perspectives: (1) scientific researches needed by scientists, (2) management and institution formulation needed by governments, and (3) water resource optimal allocation by the manager at all administrative levels.

Abstract As water use is closely associated with economic activities, a growing population, agricultural development, and reallocation of water resources, the Heihe River Basin highlights common issues of water productivity and groundwater overexploitation. We conducted a quasi-dynamic input–output analysis to investigate the changes to water use among different sectors of Zhangye city from 2002 to 2012, and clarified the driving mechanism of these changes. Our results indicated that the direct agricultural water use coefficient (calculated with an input–output table and other water use data) was the largest among the coefficients from all the sectors; notably, the fishery sector still consumed about 1 m3 of water per unit output in 2012. We found that the water-saving technologies clearly contributed to the decrease of agricultural water from 2002 to 2007, but induced a rebound in total water use from 2007 to 2012. This study provides insights into the challenges of water resource management in the Heihe River Basin and sheds light on potential water-saving strategies for the future. This study may also enhance the policy relevance of land use governance and industrial transformation. A comprehensive exploration of the water–ecosystem economy is critical to integrated water resource management.
