Water management in green economy
Human well-being(social and human capital)
goal: enhance social equity
and fair burden-sharing
Ecosystem(natural capital)
goal: ensure
ecological resilience
Economy(manufactured and
financial capital)

Water accounts• Water balances in a strict
accounting framework so to link the physical and economic worlds
• The accounting spatial unit: ‘territory of reference’, made of ‘statistical units’
• Analysis carried out across the inland resource system (natural assets) and the economy
• Exchanges between the different components: rain on soil that receives irrigation; rivers fill reservoirs used for abstraction and supply; etc.
• Applies to the physical catchments

Soil water deficit:
•higher annual deficit in southern Europe (in average 400 mm/year in period 2061-2080)
•the largest changes in Mediterranean area and Turkey•in central and northern Europe lower annual deficit is projected•in far north increase in deficit is projected - frozen soils and snow ??

EU information systems – Presenting information
is gateway to information on European water issues
aims to support Europe in adapting to climate change
is a single entry point for data and information on biodiversity in the EU

What is Climate-Adapt?
The European Climate Adaptation Platform (CLIMATE-ADAPT) aims to support Europe in adapting to climate change. It is an initiative of the European Commission and helps users to access and share information on:
1) Expected climate change in Europe2) Current and future vulnerability of regions and sectors3) National and transnational adaptation strategies4) Adaptation case studies and potential adaptation options5) Tools that support adaptation planning
