“…Climate change sensitivity scenarios of higher flow (þ20%) and lower flow (À20%) than base case level in the Blue Nile represent one of the only HEMs on transboundary issues we reviewed that considered this factor (Satti et al, 2015). Several of the reviewed HEMs considered hydropower price uncertainty (Jeuland et al, 2017;Pakhtigian et al, 2019). The current price and half this amount 8 to 4 cents kW/h were considered by Satti et al (2015).…”

Review of hydro-economic models (HEMs) which focus on transboundary river water sharing disputes

Hydro-economic models (HEMs) are powerful tools to analyze water scarcity, drought, and water management problems. Though several HEMs reviews have been conducted in the recent past, none of them focused on the management of transboundary river water disputes, benefit sharing, or trade-offs. Therefore, this review explored how HEMs can suggest mitigating water sharing disputes on transboundary rivers. Though more than 300 HEMs have been developed worldwide, very few focused on transboundary river water disputes. After vigorous screening at Google Scholar, only 25 articles were found which focused on transboundary river water disputes. Most HEMs that were reviewed proposed to share benefits such as sharing hydropower produced from the river, reallocating water from low-value agriculture to high-value agriculture or managed operation of the dam, or other monetary compensation. But no study assessed non-water sector benefit sharing such as trade or transit. Most HEMs focused on irrigation and hydropower which are benefits from the river and very few studies focused on fisheries, environment, and wetland which are benefits to the river. International rivers can act as a catalyst among the riparian countries and promote cooperation in trade, commerce, exchange of technologies, and other fields. HEMs can play an important role in this regard. It is to be mentioned that HEMs cannot resolve water conflicts in a shared basin, they only can propose for the options of solution.

These include work on water issues in India (Pande et al, 2011;Satoh et al, 2017;Zekri et al, 2017;Nechifor and Winning, 2018;Amjath-Babu et al, 2019;Pakhtigian et al, 2020), Bangladesh (Flanagan et al, 2012;Mullick et al, 2013;Ray et al, 2015;Amjath-Babu et al, 2019), and Pakistan (Yang et al, 2013(Yang et al, , 2016aSatoh et al, 2017;Amjath-Babu et al, 2019;Ali et al, 2020).…”

Successful climate adaptation needs to sustain food, water, and energy security in the face of elevated carbon emissions. Hydroeconomic analysis (HEA) offers considerable potential to inform climate adaptation plans where water is an important element of economic activity. This paper's contribution is to identify how HEA can inform climate adaptation plans by minimizing economic costs of responding to climate induced changes in water supplies. It describes what HEA is, why it is important, how researchers implement it, who has made significant contributions, and places where it has informed policy debates. It also describes future directions for the use of HEA to guide climate adaptation.

“…There are multiple lines of evidence that most parts of the world, especially agricultural-dominant areas, have perceived the negative impacts of climate change on water supply, and the supply-demand contradiction will lead to more severe water shortages in the future [7]. Many residents in developing countries are disadvantaged concerning access to adequate domestic and agricultural water because of the severe mismatch between water supply and demand resulting from the effects of climate change, environmental degradation, the low performance of existing water supply systems, and improper management of these systems and their sustainability [8,9]. Human-induced climate change, with its negative impacts on the water supply in many less developed regions, has given rise to sustained interest in assessments of water stress [10].…”

Water scarcity is one of the leading challenges for sustainable development in the context of climate change, particularly for agriculturally reliant countries. Inadequate water supplies tend to generate environmental and health issues. Improvements in water supply systems should give priority to the region with the most severe mismatch between water supply and demand. To set priorities for the improvement of water supply systems, this study proposed a water supply-demand balance model to quantify the water supply-demand gap in the Koshi River basin and compared it with the traditional water vulnerability model. The results suggested that (1) the water supply-demand balance model had good applicability to the Koshi River basin and was superior to traditional models in identifying the region with the most severe mismatch; (2) the shortage of agricultural water was much more serious than that of domestic water in the basin; (3) the largest supply-demand gap of domestic water was in Tarai and that of agricultural water was in the hill areas; and (4) Four districts, including Lalitpur, Mahottari, Makwanpur, and Solukhumbu, were found to be the most water-stressed regions and priority should be given to them. Based on these findings, the priority setting in the improvement of water supply systems and adaptation strategies for mitigating water stress from the perspectives of the government, communities, and households were presented. It helps design water supply systems that match heterogeneous demands and optimize systems operation. Targeted improvements in water supply systems can make limited funds available to benefit more residents.
