What is water scarcity and droughts?
Droughts
Temporary decrease in water availability due – for instance
– to rainfall deficiency
Natural phenomenon
Impacts of droughts in case of water scarcity
Water scarcity
Water demand for human activities exceeds water resources available
and the natural recharge
Human-driven phenomenon
Impacts of water scarcity in case of drought

The climate is already changing
![Page 9: 1 st i-adapt workshop: Water Scarcity and Draught: Context and Approach](https://reader036.vdocuments.mx/reader036/viewer/2022081603/56813a63550346895da25ad4/html5/thumbnails/9.jpg)
And could be getting worse…..
![Page 10: 1 st i-adapt workshop: Water Scarcity and Draught: Context and Approach](https://reader036.vdocuments.mx/reader036/viewer/2022081603/56813a63550346895da25ad4/html5/thumbnails/10.jpg)
Why is water scarcity & droughts a concern in Europe?
• Balance between demand and availability has reached a critical level in many areas of Europe (water scarcity)
• More and more areas are affected by weather changes, in particular less rain (droughts)
• Climate change will almost certainly make the situation worse • More frequent and severe droughts expected across Europe and the
neighbouring countries• Total water abstraction in EU 247 billion m³/year
– 44% for energy production, – 24% for agriculture, – 17% for public water supply – 15% for industry
Business as usual scenario: Total abstraction will increase by 16% by 2030
![Page 11: 1 st i-adapt workshop: Water Scarcity and Draught: Context and Approach](https://reader036.vdocuments.mx/reader036/viewer/2022081603/56813a63550346895da25ad4/html5/thumbnails/11.jpg)
Potential for water savings:• Potential for water savings in the EU nearly 40%
– technological improvements alone – Further increased by changes in human behaviour or production
patterns • Water Supply infrastructure: potential saving up to 33% of
today’s abstraction• Agriculture: potential saving 43% of current agricultural
abstraction from: – Improved efficiency - 15% to 60% of water use. – changes in irrigation practices (30%), – use of more drought-resistant crops (up to 50%)– reuse of treated sewage effluent (around 10%)
• Industry: estimated savings 15 - 90% average 43%• Tourism: potential of 80-90% savings• Irrigation of golf courses and sporting areas: 70%

What’s nextIn 2012, the Commission will publish a "Blueprint to Safeguard European Waters"
– Review of the implementation of the Water Framework Directive (includes Water efficiency of buildings)
– Review of the Strategy for Water Scarcity and Droughts – Review of the vulnerability of water and natural resources
to climate impacts and man-made pressures.
![Page 13: 1 st i-adapt workshop: Water Scarcity and Draught: Context and Approach](https://reader036.vdocuments.mx/reader036/viewer/2022081603/56813a63550346895da25ad4/html5/thumbnails/13.jpg)
Key challenges for the Blue Print
• Costs and Competition for water supply– Transfers– Desalinisation– GW extraction
• A water and env. resources efficient economy
• Ecosystem-based approach• Facing gradual changes &
extreme events
• Trade-offs/conflicts between:– Economy & ecosystems– Sectors– Regions– Land / sea
• Instruments– Pricing / regulation
• Land-use planning– Room for the river– Water (& carbon) retention
![Page 14: 1 st i-adapt workshop: Water Scarcity and Draught: Context and Approach](https://reader036.vdocuments.mx/reader036/viewer/2022081603/56813a63550346895da25ad4/html5/thumbnails/14.jpg)
Main information needs now - 2012
• Water Framework Directive:– information base: the River Basin Management plans– key issue: comparability of information in the plans
• Water Scarcity and Droughts:– a wide range of data regarding the scale of the problem, the effectiveness of existing
policy measures and the costs and benefits of possible additional measures, information on water availability, water allocations
• Vulnerability of environmental resources:– methods, models, data sets, prediction tools and indicators to better monitor the impact
of climate change– including vulnerability impacts and progress on adaptation
• Studies launched to assess the possible introduction of measures for water efficiency in agriculture, in buildings and leakage reduction in the supply systems

Action at EU level: Commission Communication WS&D 2007 - 7 policy
options• Putting the right price tag on water• Improving drought risk management• Fostering water efficient technologies and practices• Fostering the emergence of a water-saving culture• Allocating water & water-related funding efficiently• Considering additional water supply infrastructures• Improve knowledge and data collection
![Page 16: 1 st i-adapt workshop: Water Scarcity and Draught: Context and Approach](https://reader036.vdocuments.mx/reader036/viewer/2022081603/56813a63550346895da25ad4/html5/thumbnails/16.jpg)
What are we looking at?
WS & D GAP Analysis:– Overview of problem & existing measures
• Where is WS&D a problem & how big is the problem?• What are the driving forces?• What & how big are the pressures?• What are the impacts?• Which measures are already in place?
– Identification of gaps – Proposal of new measures– Assessment of Impact of new measures
![Page 17: 1 st i-adapt workshop: Water Scarcity and Draught: Context and Approach](https://reader036.vdocuments.mx/reader036/viewer/2022081603/56813a63550346895da25ad4/html5/thumbnails/17.jpg)
WS&D - the basic principle:the water hierarchy
• Address demand side measures first:– demand management– water-saving– water efficiency– water-pricing
• Only then additional water supply infrastructures:– water transfers – desalination plants – waste-water re-use– etc.
![Page 18: 1 st i-adapt workshop: Water Scarcity and Draught: Context and Approach](https://reader036.vdocuments.mx/reader036/viewer/2022081603/56813a63550346895da25ad4/html5/thumbnails/18.jpg)
Other areas:
• Alternative water supply • Waste water re-use…• Water consumption in products
– water related information on food and agricultural products
– Assessment of the reliability and effectiveness of the "water footprinting" method
• Eco design, Green Public Procurement
