Overview of Climate Adaptation presentation CC impacts as an environmental hazard CC impacts in the ENPI East Regional context Outline of Assessment Method Results Qualitative Quantitative Conclusions: Next steps for policy use 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 2
CC Impacts Environmental Hazard CC increasingly recognised as significant hazard in all ENPI East countries. Accumulating evidence showing currently observed CC impacts in many sectors, including water resources, coastal regions, human health, forestry, agriculture, critical infrastructure and ecosystems. Impacts are cross-sectoral and projected to increase in future time periods 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 3
Climate change adaptation Adaptation: changes to natural sytems or human practices in response to actual/expected climatic change or its effects. Example of adapation measure in agriculture: adoption of crop varieties that tolerate better drought or water CC mitigation: practices that reduce the probability of climate change by reducing atmospheric concentrations of GHG, e.g. cleaner energy. 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 4
CC Impacts Drivers GHG (CO2, and equiv.) emissions from fossil fuel combustion, deforestation, agriculture and industrial practices (+ natural phenomena) result in atmospheric warming: Global average temperatures risen since mid-20 th century Global sea-level rise (SLR) observed to date Increase in frequency of some extreme weather events observed Uncertainty remains in CC modelling 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 5

ENPI-East regional Context Regional climate effects include: Mean temperature (0.41C/decade from 1979) up to + 5.5C by 2100 frequency of extreme weather events, particularly intense rainfall events, has increased in recent decades: floods Summer rainfall decreasing Global sea level rise Identified trends likely to be exacerbated by future climate change 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 7
Case Study: Azerbaijan Sea level rise: Caspian Sea coastline vulnerable to fluctuations in water levels e.g. Absheron Peninsula, heavily populated. Water resource availability and scarcity: availability is forecasted to fall by around 25% by 2030 Increased risk of flooding: both inland and along the Caspian Sea coast Increased frequency and severity of high temperature events: most significant in urban heat islands 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 8
ENPI East regional context Impacts: Multi-sectoral; mainly negative; predominantly in urban areas, where residential areas close to industry Trends: exacerbation of those observed to date, though uncertainty over decades to 2100 since rate and extent of CC not known Previous studies in other world regions, plus ENPI national studies, show significant benefits of climate impact reductions by implementing measures to reduce impacts = climate change adaptation 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 9

Results from the BAs for ENPI East countries (1): qualitative Environmental benefits Description Ecosystem condition improvements - Development of protected corridors for species migration is being promoted on a regional basis. - Pro-active forest management strategies being developed to protect diversity of wood species and composition of forests; as well as the accessibility of forests for population recreation purposes and role of forests in fire control. 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 15
Results (2) Health benefits Description Lower incidence of acute health impacts - The introduction of heat warning systems in urban areas should be effective in reducing the mortality and morbidity consequences of vulnerability to heatwaves. - Disease monitoring systems may be used to contain the spread of vector-borne diseases that may spread as a consequence of flood events or changes in temperature vectors. 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 16
Results (3) Social benefits Description Improved quality of life Reduced health effects Investments in water, soil and coastal restoration for adaptation purposes may help to improve community well-being and provide new opportunities for employment and recreation. 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 17
Results (4) Economic benefits Protect current production. Description - Adaptation to threats to agricultural yield from water scarcity, through more efficient management practices would result in some protection of farm incomes and local economies. - Increase in demand for products and processes that result in greater adaptation, e.g. Investment in coastal defence systems boosts construction sector. Exploit new opportunities Increase in tourism and associated expenditures in local areas. These tourism benefits will be realised if, for example, coastal protection and management reduces the threat to coastal amenities 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 18
Case study: Moldova qualitative benefits Benefits of adapting to reduced water resource availability - from reduced water use or investment into more secure supply - can be found in facilitating its uses. Social/economic benefits: Increased availability secures growing & marketing of food. Employment opportunities in agricultural sector maintained Considering the impact of locally grown goods on food prices, the maintained yields of crops secure a competitively and socially desirable pricing. Health benefits: Food security/clean drinking water sources lead to an improved health and the avoidance of malnutrition and related diseases. Positive environmental benefits in slowing down land erosion. 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 19

Quantitative benefits: Case Study Armenia: Projected volume of snow 7-11% by 2030, water balance of Lake Sevan will fall significantly. river flow will reduce by 0.6 billion cubic meters by 2030. areas needing irrigation will expand, otherwise: a decline of 8-14% in the yields of the main agriculture crops is projected (9-13% for cereals, 7-14% for vegetables, 8-10% for potato and 5-8% for fruits). Benefits of investment in effective irrigation (adaptation measure): agricultural yield losses prevented 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 21
Conclusions (1) Benefits of reducing CC Impacts in Eastern ENPI countries likely in: Water resource use (domestic, industry, agriculture) Resulting from, e.g. technological measures including: reduction of losses in the irrigation and drinking-household water supply system through repairs of the systems and pipelines; accumulation of moisture (water) in irrigated fields through storage of snow or snow melt water; replenishment of moisture through early spring sowing of crops in rows, deepening irrigation ditches and using polyethylene covers 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 22
Conclusions (2) Benefits of reducing CC Impacts in Eastern ENPI countries likely in: Coastal areas (settlements, infrastructure, ecosystems) Resulting from, e.g. construction and maintenance of coastal protection measures Appropriate land use zoning 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 23
Conclusions (3) Benefits of reducing CC Impacts in Eastern ENPI countries likely in: Areas of flood vulnerability ((property, infrastructure, human health, agriculture) Resulting from, e.g. Investment in higher dikes Appropriate land use zoning 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 24
Conclusions (4) Benefits of reducing CC Impacts in Eastern ENPI countries likely in: Urban Heat Islands (health risks of heat-waves) Resulting from, e.g. Heat alert systems implementation Awareness raising re. need for continual hydration Investment in cool rooms 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 25
Conclusions (5) CC Adaptation Benefits exacerbate those identified in other parts of BA Significant uncertainty in each part of the impact pathway ( in climatic variable exposure - impact) BA project under-estimates since does not include all CC Impacts. 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 26
Recommendations Dissemination of these results should raise awareness and add impetus to need for increased planned adaptation Further country-specific analysis should be complemented by looking at costs and benefits effects of planned adaptation over vulnerable populations 23-24.06-2011 Final Project Event:ENPI-East, Chisinau 27
