Climate Change Impacts and Adaptation: Quantify the Cost of Impacts and Adaptation Metroeconomica UK Water scarcity & droughts

Two case-studies in SE England and SE Scotland. Net benefit estimated as difference between (a) the economic losses to households of restricted supplies and (b) resource costs of removing deficits. It used existing studies to estimate the economic losses to households for foregone water use because of the anticipated water deficit up to 2100 using a revealed preference approach. The report then assessed the cost of addressing this water deficit, using information on the range of options available for managing the public water supply, and by constructing indicative cost-yield curves.

Assessing the robustness of adaptation decisions to climate change uncertainties: A case study on water resources management in the East of England. Dessai, S.; Hulme, M. UK Water scarcity & droughts

Robust decision-making analysis - The framework is applied to a case study of water resources management in the East of England, to the Anglian Water Services’ 25 year Water Resource Plan (WRP). Includes local sensitivity analysis of the various elements of the modelling framework in order to determine whether or not a decision to adapt to climate change is sensitive to uncertainty in those elements.

Water Resources Planning under Climate Change: A “Real Options” Application to Investment Planning in the Blue Nile Jeuland, M.; Whittington, D. Egypt Water scarcity & droughts

A real option analysis for dam construction in the Blue Nile. smaller storage projects perform better when inflows are low and upstream withdrawals are high. Higher storage better in opposite situation when hydropower generation is greater. Highest expected NPVs, Delaying dam construction leads to  high NPV loss (due to foregone benefits).
