Study Case: Evaluation of Water Stresses at the River Basin Scale: The Haihe River Basin
Water resources managements at river basin scale face the challenges of unbalanced water distributions among different regions and economic sectors. The involvement of multiple regional jurisdictions further complicates the optimal allocation and sustainable management of water resources at river basins. Water stresses analysis based on water footprint accounting is an applicable approach in assessing the sustainable utilization of water resources for river basins. In this chapter, based on the blue and gray WFs accounting of different economic sectors, as well as an extended Environmental IO Analysis, the evaluations of the water stress in terms of quantity and quality were conducted at the river basin scale. Additionally, the spatial correlation analysis based on their relevant water stresses indexes were conducted via the ESDA model for the illustration of the spatial correlation distributions of the water stresses of the cities within the HRB. The results of the study on WF evaluation for river basin would be useful for assessing water endowments and supporting decision-making in water allocation among the cities and economic sectors within the river basin.
