| 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. |
| Adapting to climate change with water savings and water reuse | Anderson, J. M. | Australia | Water scarcity & droughts |
Case Study for Sydney, including a set of adaptation options: leakage reduction program, water efficiency labelling, rebates for rainwater tank, recycled water for gardening/toilet; flushing; water storage,, water transfer. Cost functions used and added to the stochastic analysis model to record investment and operating costs for drought contingency works and cost to consumers of water restrictions during droughts, measured using loss of consumer utility function. |
| The environmental, economic, and social impacts of climate change in Greece | Bank of Greece | Greece | Water scarcity & droughts |
Use of cross-sectoral general equilibrium model. Modelled as additional public expenditures, benefits are avoided damages. Benefit-cost ratio substantially higher than 1 |
| Water resource planning under climate uncertainty in London | Darch, G.; Arkell, B.;Tradewell, J. | UK | Water scarcity & droughts |
Assess effects of long term climate uncertainty on investment planning in London, including impact on reliability of resources, on cost-effectiveness of supply-demand options, and on investment decisions and robustness of option programmes. Draws on existing data and techniques for extrapolating for future climate scenarios and simple re-assessment of costs and benefits. |
