Indicator Specification
Water is an indispensable resource for human health, ecosystems and socio-economic activity. From a resource perspective, river flow is a measure of sustainable fresh water availability in a basin. Variations in river flow are determined mainly by the seasonality of precipitation and temperature, as well as by catchment characteristics such as geology, soils and land cover. River flow can be used as an indicator because changes in temperature and precipitation patterns due to global warming modify the distribution of water at the land surface, and consequently the annual water budget of river basins as well as the timing and seasonality of river flows. The consequent changes in water availability may adversely affect ecosystems and several socio-economic sectors such as water management, energy production, navigation, irrigation and tourism.
In view of projected global warming and the associated changes in water availability, it will become increasingly important to balance competing societal, industrial, agricultural and environmental demands. Sustainable options for mitigating the effects of changes in water availability include improved water efficiency, the re-use of water, and metering and water pricing to stimulate awareness and encourage water conservation.
In April 2009 the European Commission presented a White Paper on the framework for adaptation policies and measures to reduce the European Union's vulnerability to the impacts of climate change. The aim is to increase the resilience to climate change of health, property and the productive functions of land, inter alia by improving the management of water resources and ecosystems. More knowledge is needed on climate impact and vulnerability but a considerable amount of information and research already exists which can be shared better through a proposed Clearing House Mechanism. The White Paper stresses the need to mainstream adaptation into existing and new EU policies. A number of Member States have already taken action and several have prepared national adaptation plans. The EU is also developing actions to enhance and finance adaptation in developing countries as part of a new post-2012 global climate agreement expected in Copenhagen (Dec. 2009).
