Berlin, 12 To 14 February 2007 6
Discussion on Key questions - I• Q: Impacts and vulnerability: Greatest challenges for adaptation? Benefits to be
expected? Regions be most affected?
• Higher climatic variability (what to adapt to?)
• Different responses in South (lack of water) and North (lack in summer – excess in winter). Central Europe may be particularly affected through increased climatic variability.
• Benefits include longer vegetation period (North) and possible change in vegetation period (South)
• The timeframe of changes in vulnerability depends on whether change in mean conditions or change in variability is considered
• Increasing pressure on irrigation systems and water supply in South (in particular in intensively irrigated regions)
• Increased nutrient losses in North leading to negative effects on aquatic ecosystems (in particular near lakes or brackish waters)
• Increased pest and diseases (Central and North), need for more pesticides

Discussion on Key questions - I• Q: Adaptation options: Available options? How to decide about
implementation?
• Farm management: e.g. cultivation intensity, crop choice, sowing date, insurance, measures to reduce nutrient losses to aquatic environments
• Watershed management: Pricing of water, landscape (wetland. riparian land) management, land use planning
• National/EU management: Implementation and enforcement of regulations (WFD), changing subsidies related to irrigated crops
• Technologies: water conservation (e.g. mulching, conservation tillage), improved irrigation efficiencies (e.g. night time irrigation), improved varieties, cleaning of dirty/saline water
• Water management: Timing of water availability for irrigation, need to save water for later use (climatic variability)
• Education and advice is needed to ensure efficient adaptation at farm and regional scales

Discussion on Key questions - I• Q: Policy action: What could be gained from EU level action? Modifications of
CAP? How to ensure consistency of different policies?
• Adjustment is needed of the CAP to include climate change aspects, in particular in relation to water use and protection of aquatic environment
• Resource (e.g. water framework directive) policies and environmental (e.g. biodiversity) policies need to be fully implemented and include climate change aspects
• Adjustment of policies need to account for regional differences in response to climate change
• Need to better understand interactions among climate change and adaptation at various levels in society, which will determine policy efficiency and consistency
• Need to integrate also policies for developing countries

Discussion on Key questions - II• Q: Integrated approach: Role of agriculture in integrated adaptation
strategies? Relationship with adaptation measures in other sectors?
• Integrated agriculture and land use planning to save and protect water resources and provide flood protection
• Nature conservation issues should be integrated in agricultural land use management (amount and quality of water in aquatic ecosystems)
• Conflict between objectives of individual farmers and objectives of the society
• Landscape scale conflicts, e.g. related to management of excess water from urban/built areas.
• Conflicts with other human use of water (e.g. navigation, tourism, cooling of power plants)
• Relations with mitigation options (e.g. biofuel production)
• Enhancement of waste water reuse, e.g. for irrigation purposes

Discussion on Key questions - II• Q: Conflict resolution: How to mitigate conflicts between
agriculture and other water users? Criteria for decision-making and allocation?
• Improve awareness of possible conflicts
• Implement decision structures involving all stakeholders
• Introduce market based instruments. This includes reform of water rights and introduce water charges appropriate for different users of water, in order to promote efficiency of water use

Discussion on Key questions - II• Q: Economic instruments: How to share the costs of
adaptation? Cost-recovery principle?
• Distribute costs according to amount of water consumed
• Costs for protecting aquatic systems against pollution should be covered by the polluter
• Redirect some of the CAP support (e.g. agro-environmental schemes) towards supporting implementation of increased water use efficiency in agriculture and for protecting aquatic ecosystems

Discussion on Key questions - III• Q: Funding: Use of funding mechanisms to support and
encourage adaptation?
• Further reform of the CAP and redirection of funding towards supporting higher water use efficiency and protection of water resources and aquatic environments
• Use of EU and national research and innovation capacities towards developing technologies that increase water use efficiency and protect aquatic ecosystems
• EU structural and cohesion funds may be used to support adaptation
• Funding also needs to go into communication and awareness raising

Discussion on Key questions - III• Q: Avoiding social impacts: Social and distributional impacts to
be expected? How to avoid social hardship?
• Effects of climate change and water use interact with current trends of increased urbanisation and pressures in rural development
• Reductions in agricultural productivity from climate change may be substituted by increases in other rural activities (diversification), e.g. tourism
• Abandonment of agricultural land may be needed in some regions, and planning is needed for this to limit social impacts

Discussion on Key questions - III• Q: Research needs: Knowledge gaps with regard to impacts, vulnerability and adaptation
options?
• How will increasing CO2 concentration affect the overall water use and water use efficiency of various crops under European growing conditions?
• How will a change in climatic mean and variability affect the water use, crop yields and applicability of various adaptation options?
• What are the possibilities of optimising water use by shifting cropping seasons, changing crops and adopting water conserving practices?
• How will adaptation options affect environment and biodiversity?
• Will current options for reducing environmental impacts of quality of aquatic systems be efficient and sufficient under climate change?
• How to integrate agriculture in land use planning to save and protect water resources?
• Need for regional studies because impacts and adaptations vary strongly within Europe
