TL;DR: In this paper, the authors address the importance of water quality management and the impacts of water pollution control and water development projects in the Huai River Basin and identify three urgent issues for water and ecosystem interactions on the river system.
Abstract: This paper addresses the importance of water quality management and the impacts of water pollution control and water development projects. The case study of the Huai River Basin is an example of the major challenges on water quality management that China is facing, and why water quality management will play a key role on its sustainable use and management. Three urgent issues for the Huai River Basin are identified: water and ecosystem interactions on the river system due to the impacts of increasing pollution and water development projects; comprehensive assessment on impact of dams and sluices on changes of river flow regimes, water quality and ecosystems; and improvement of water quality, and the restoration of river ecosystems through state-of-the-art environmental monitoring and integrated water management practices.

TL;DR: In this paper, the authors used the Protection Motivation Theory (PMT) to understand farmers' behaviors at the farm level in response to water shortage due to climate change, and found that model variables accounted for 39 % of variance in farmers' adaptation behaviors.

TL;DR: In this article, the authors examined market-based water allocation as an alternative option to the traditional administrative allocation to deal with water scarcity issues in the Aral Sea Basin (ASB) where ineffective water management institutions are the primary reason of intersectoral and interstate water sharing conflicts and lack of incentives for improving water use efficiency.

TL;DR: In this article, a catastrophe theory based multi-criteria evaluation model has been proposed to assess water security under different management strategies to recommend the best water management strategy to achieve water security in the context of global environmental change.
Abstract: Economic development, population growth, urbanization and climate change have led to an increasing water shortage across the globe. Ensuring water security under changing environment will be the greatest challenge for water resources managers in near future. In this paper, catastrophe theory based multi-criteria evaluation model has been proposed to assess water security under different management strategies to recommend the best water management strategy to achieve water security in the context of global environmental change. The assessment model involves future scenarios of climate change, population growth and economic development. Total 16 indicators related to climate, socio-economy and water availability and consumption have been proposed to measure water security under three management strategies viz. business-as-usual, water demand management and water supply management. The model has been applied to Yulin city of North West China to assess water security as well as to identify the water management strategy under changing environment. The results show that under business-as-usual situation the water shortage rate will reach up to 44 % by the year 2020 and up to 70 % by the year 2030 in Yulin. Water supply is required to increase by 41 % to meet the water demand under supply management strategy which is beyond the safe baseline rate. The study reveals that water demand management can reduce the gap between water supply and demand to a reasonable amount and therefore, can be considered as the most effective approach for adapting with environment change.

TL;DR: In this paper, the authors analyzed the uncertainties in water supply of Alberta by building an agro-hydrological model, which accounts for major hydrological features, geo-spatial heterogeneity, and conflicts over water-food-energy resources.
