Climate change
Climate change is unequivocal IPCC AR4
Observed changes Global average temperature Global average sea level Northern hemisphere snow cover
The frequency of heavy precipitation events has increased over most land areas - Rainfall in Mumbai (India), 2005: 1 million people lost their homes
Tropical cyclones have increased in intensity over the past 3 decades - Cyclone Nargis in Myanmar, 2008: 100 000 estimated deaths
Projected surface temperature changes (2090-2099 relative to 1980-1999) 0 1 2 3 4 5 6 7 ( o C) Continued emissions would lead to further warming of 1.8ºC to 4ºC over the 21 st century and induce many changes that would be larger than those observed during the 20 th century
Key vulnerabilities in the Asia-Pacific region
Vulnerability of coastal deltas Extreme (> 1 million people potentially displaced by current sea-level trends by 2050) High (50 000 to 1 million) Medium (500 to 50 000)
Human health Endemic morbidity and mortality due to diarrhoeal diseas primarily associated with floods and droughts Exacerbation of the abundance and toxicity of cholera due to increase in coastal water temperature Increased deaths, disease and injury due to heat waves, floods, storms, fires and droughts
Food production Crop yields could increase up to 20% in East and Southeast Asia while they could decrease up to 30% in Central and South Asia by 2050 Future changes have the potential to substantially alter the abundance of fish populations in Asian waters The risk of hunger is projected to remain very high in several developing countries
Water availability Glacier melt is projected to affect water resources in the next decades Rivers in the northern Indian plain could become seasonal in the near future Decreasing winter precipitation over the Indian subcontinent would imply less groundwater storage Saltwater intrusion in groundwater and estuaries is projected to be aggravated by sea-level rise. 120 million to 1.2 billion people will experience increased water stress in South and South East Asia by the 2020s
Adaptation and mitigation strategies
Key adaptation strategies Developing knowledge on impacts and vulnerabilities Integrating adaptation in wider policies (Ex. Integrated Coastal Zone Management) Improving disaster preparedness and management Improving health care systems Promoting good governance including responsible decision making and communities empowerment Poverty is the largest barrier to developing the capacity to cope and adapt
Role and limits of adaptation Societies have a long record of adapting to the impacts of weather and climate But climate change poses new risks that will require new investments in adaptive responses Adaptation is necessary to address impacts resulting from the warming which is already unavoidable due to past emissions But adaptation alone is not expected to cope with all the projected effects of climate change

Challenges in S Asian Countries Promoting equity in spreading the benefits that will arise from economic growth Implementing appropriate regulatory intervention to ensure adequate food supply in the context of increasing value of land Finding new development pathways wherein GHG emissions and the use of natural resources are minimised
