CCDeW: Climate Change and Demand for Water.

Abstract

The Climate Change and Demand for Water Revisited project (CCDeW) revisits and
\nupdates the benchmark study by Herrington (1996) and takes advantage of new data
\nsets, regional coverage of demand projections and new methodologies for climate
\nimpact assessment. Domestic demand, industrial and commercial water use and
\nirrigated agriculture and horticulture are included in the CCDeW study. Leakage
\nwas excluded from the CCDeW study. This report presents the outcome of an
\nextensive UK research programme concerning: demand forecasting; demand
\nmanagement; sensitivity of demand to climatic variations; and sources of risk
\nand uncertainty. While the CCDeW study focuses on demand, climate change
\nuncertainties feed into supply side and demand estimates of water requirements.
\nTherefore, the report’s conclusions should be seen as one element in the dynamic
\nmanagement of the supply/demand balance over the course of the next twenty years
\nand beyond (see Section 9). Clearly, the extent to which water consumption will
\nbe influenced by climate change depends upon the sensitivity of different
\nsectors to specific aspects of climate change as well as potential behavioural
\nand regulatory changes, in part related to different socio-economic and climatic
\nfuture
