|Description=Water plays an important role in many natural and human processes. Its availability is essential for natural vegetation and agricultural production, for human settlements and industry. Around one third of the worlds’ population is living in countries already suffering from ‘medium’ to ‘high’ water stress ([[OECD, 2012]]). This number is expected to increase further, due to a growing population that will need more water and is living in a changing climate. | |Description=Water plays an important role in many natural and human processes.

Key policy issues
- What is the combined effect of climate change and socio-economic development on water demand and availability, and on associated agricultural production?
- What is the potential of adaptation measures to reduce water stress and water-related crop production losses?
- How can water demand be reduced and still provide the adequate service levels to the sectors with the highest demand?
