Outermost Regions & Climate Change António Domingos Abreu
Small Islands and ORs Reduced size Limited natural resources Natural disasters Isolated Vulnerable and exposed economies High population density Vulnerable natural systems
Main climate change impacts - ORs and small islands Sea level rise Changes in wind and rain regimes Soil balance changes Changes of local wave and near shore sea conditions Coastal based socieconomical activities
Climate Change - main trends Increase of mean temperature Sea level rise Less precipitation More frequent extreme events
Special issues Development, sustainability and equity, Sea level rise Coastal changes Biological systems and biodiversity Water, agriculture and fisheries Human health, settlements, infrastructures and tourism
Development, sustainability and equity < 1% of GHG contribution Exposed and vulnerable economies Need of scale adaptation measures
Sea level rise 5mm/year in the next century Social and economical implications Adaptation within their natural and social boundaries...
Coastal zones Human contribution to coastal zone change In the next 50 to 100 years these changes will increase Need to assure resilience of coastal zones Higher social and economical costs of adaptation
Natural systems and biodiversity Natural systems are the basis of the economical stability of ORs 33% of the endemic species of the flora are insular endemisms 23% of the insular bird species are endangered Changes in the composition, structure and dynamics of natural systems
Water, agriculture & fisheriess Water availability and food production will always be critical factors in the ORs Most of water is from rain origin Loss of soil, erosion, saline intrusion, Changes in the abundance and distribution of fisheries
Human health, settlements, infrastructures and tourism Potential increase of biological induced and water related diseases More critical situations linked to extreme events Vulnerability of infrasctructures, including touristic and those located on risk zones,
Adequated and adapted management Information Monitoring Mitigation Adaptation
Scenarios & models

Potential Impacts on forest and agriculture Changes in the distribution zones - altitude; Higher forest fire risks; Changes on primary production.

Levels of air polution Contamination vectors Transmission dinamics Regional Climatic changes Extreme events Temperature Precipitation Potential effects on human health Death/diseases due to temperature & climatic extreme events (floods/dry/rain) air polution related effects Diseases promoted by water and food Diseases transmited by bilogical vectors Human Health
The near future Climate change is a fact It is prioritary to monitor the trends Mitigation and adaptation measures Participation Is this possibe to deal with climate change challenges on a ORs scale?
