Rationale
Justification for indicator selection
Climate change may affect agriculture primarily through increasing atmospheric CO2, rising temperatures and changing rainfall. Where rainfall does not limit crop growth, these conditions allow for earlier sowing dates and enhanced crop growth and yield (see previous indicators). Where reduced rainfall is predicted, however, the increased requirement for irrigation water can have an overall negative impact in economic and environmental terms. In these areas, increased water shortages are expected to increase competition for water between sectors (tourism, agriculture, energy, etc.) particularly in southern Europe where the agricultural demand for water is greatest. Several adaptation options are available to mitigate the risks of water shortage. Increased irrigation can further burden surface and groundwater resources and increase greenhouse gas emissions, adding to the mitigation challenge.Scientific references

Policy context and targets
Context description
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).
