Why is adaptation important ?Why is adaptation important ?

• Climate change cannot be totally avoided• Anticipatory adaptation can be more effective

and less costly than “retrofitting” or “emergency adaptation”

• Climate change may be more rapid and pronounced than currently known

• Immediate benefits from adaptation to current climate variability and extreme events

• Avoid maladaptive policies and practices

Direct losses from weather and climate Direct losses from weather and climate related disastersrelated disasters

•The number of disastrous weather and climate related events in Europe increased by about 65% over 1998-2007 compared to the 1980s

•About 95% of economic losses caused by catastrophic events in Europe since 1980 are attributable to climate and weather. This is mainly due to socio-economic development but changing patterns of weather disasters are also drivers.

•In the second half of the century more severe effects of climate change on economic assets

More control of water run offsMore control of water run offs

• Preventive measures including good housekeeping and rainwater harvesting

• Vegetated landscape features with smooth surfaces and a gentle downhill gradient to drain water evenly off impermeable surfaces

• Infiltration devices, such as soakaways, which allow water to drain directly into the ground

• Permeable and porous pavements• Basins, reed beds and ponds designed to hold

water when it rains • Green roofs and reuse of water

Green roofing, Europe lagging behind Green roofing, Europe lagging behind

• Stormwater management, and hence potential savings since the number of drainage outlets required on a building can be reduced

• Reduced urban heat island effect by reducing building heat loss and increasing evapotranspiration

• Creating natural green spaces in urban areas bringing benefits for biodiversity

• Reduced energy consumption and fuel costs, since green roofs provide cooling in summer and thermal insulation in winter

• Reduced air pollution• Extended roof life. The green roof protects the roof’s

waterproofing membrane, almost doubling its life expectancy

Growing season for agricultural cropsGrowing season for agricultural crops

• A further lengthening of the growing season is projected • In western and southern Europe the limited water availability and high temperature will hinder

plant growth

• The lengths of the growing season of several agricultural crops has increased in the North, favouring the introduction of new species

• Locally in the south there is a shortening of growing season, with higher risk of damages from delayed spring frost

• More variable crop yields because extreme weather events are projected to increase in frequency and magnitude

• Since the beginning of the 21st century, the variability of crop yields has increased as a consequence of extreme weather events

River flow droughtRiver flow drought

• Increase in frequency and intensity of droughts in many regions of Europe• Southern and south-eastern Europe are most prone to an increase in drought hazard, but

minimum river flows will also increase in many other regions

• Europe has been affected by several major droughts in recent decades (e.g. 2003 in central parts and 2005 in the Iberian Peninsula)

• Climate change has probably increased the frequency/severity of droughts in some regions

• Regional and local governmental organizations, NGOs and the private sector have started to adopt new policies, regulations and standards accounting for climate change (role of insurance sector)

• Measures mainly in areas with a long tradition of dealing with climate extremes such as flood defence

• Many adaptation actions have been initiated because of the substantial losses from extreme weather events in recent years

• Policies and measures designed to address long-term climate change impacts have not been developed to the same extent

56

• Scientific uncertainty (low level of confidence in climate change scenarios of extreme events at high spatial resolution)

• Policy action at regional/local level (need for stakeholder involvement; gaps in knowledge on potential adaptation policies and measures; lack of resources)

• Costs of adaptation and benefits assessments (gaps in knowledge; how to identify “win-win” or “no-regret” options, justified under many plausible scenarios)

• Coordination between sectors (how to enhance efficiency and effectiveness of measures with many organisations involved)

Challenges for integration of adaptation Challenges for integration of adaptation into other policies and measuresinto other policies and measures

57

• Need to develop policy framework at European, national and regional/local levels

• Integrate (“mainstream”) adaptation into other policies and measures

• Enhance research (EU and national) on vulnerability assessments (including scenarios), good practices and costs and benefits, with stakeholder involvement

• Improve management practices for non-climatic reasons, as potential to reduce vulnerability

• Exchange experiences amongst relevant stakeholders (public and private; EU/national/regional/local)

• Communicate risks clearly to those affected and the actions they can take
