Balancing intersectoral demands in basin-scale planning: The case of Nepal's western river basins
Basin-wide planning requires tools and strategies that allow comparison of alternative pathways and priorities at relevant spatial and temporal scales. In this paper, we apply a hydroeconomic model–the Western Nepal Energy Water Model–that better accounts for feedbacks between water and energy markets, to optimize water allocations across energy, agriculture, municipal, and environmental sectors. The model maximizes total economic benefits, accounting for trade-offs both within and across sectors. In Western Nepal, we find that surface water availability is generally sufficient to meet existing and growing demands in energy and agricultural sectors; however, expansion of water storage and irrigation infrastructure may limit environmental flows below levels needed to maintain the full integrity of important aquatic ecosystems. We also find substantial trade-offs between irrigation in Nepal and satisfaction of the institutional requirements implied by international water-use agreements with the downstream riparian India. Similar trade-offs do not exist with hydropower, however. Model results and allocations are sensitive to future domestic and international energy demands and valuations.
期刊介绍:
Water Resources and Economics is one of a series of specialist titles launched by the highly-regarded Water Research. For the purpose of sustainable water resources management, understanding the multiple connections and feedback mechanisms between water resources and the economy is crucial. Water Resources and Economics addresses the financial and economic dimensions associated with water resources use and governance, across different economic sectors like agriculture, energy, industry, shipping, recreation and urban and rural water supply, at local, regional and transboundary scale.
Topics of interest include (but are not restricted to) the economics of:
Aquatic ecosystem services-
Blue economy-
Climate change and flood risk management-
Climate smart agriculture-
Coastal management-
Droughts and water scarcity-
Environmental flows-
Eutrophication-
Food, water, energy nexus-
Groundwater management-
Hydropower generation-
Hydrological risks and uncertainties-
Marine resources-
Nature-based solutions-
Resource recovery-
River restoration-
Storm water harvesting-
Transboundary water allocation-
Urban water management-
Wastewater treatment-
Watershed management-
Water health risks-
Water pollution-
Water quality management-
Water security-
Water stress-
Water technology innovation.
