Climate change is expected to increase the severity and frequency of weather-related natural hazards such as storms, high rainfalls, floods, droughts and heat-waves (IPCC Fourth Assessment Report). Coupled with sea level rise, this will lead to more disasters in future – unless prompt action is taken.
Over the period 1995-2004, a total of 2,500 million people were affected by disasters, with losses of 890,000 dead and US$ 570 billion costs. Most disasters (75%) are related to weather extremes (ISDR disaster statistics). Of particular concern is the fact that disasters have been increasing over recent decades, mainly owing to increased populations in hazard-prone locations, unplanned settlements and environmental degradation, but evidence is also mounting that climate change is a factor too, for example in more intense hurricanes, higher rainfall intensities and heat-waves.
Climate change is altering the face of disaster risk, not only through increased weather related risks and sea-level and temperature rise, but also through increases in societal vulnerabilities from stresses on water availability, agriculture and ecosystems. Disaster risk reduction and climate change mitigation and adaptation share a common space of concern: reducing the vulnerability of communities and achieving sustainable development.
ISDR and climate change
Governments have recognized the importance of coordinating climate change adaptation with relevant natural disaster risk reduction measures and the need to integrate these considerations in a comprehensive manner into development plans and poverty eradication programmes.
For several years, the ISDR secretariat has provided information and guidance on disaster risk reduction as a tool to manage climate risks and adapt to climate change, both to inform international policy deliberations and to assist governments and other parties to reduce climate-related vulnerabilities and risk, in line with the Hyogo Framework.
Key points include:
-
Use the guidance of the Hyogo Framework for Action: Building the Resilience of Nations and Communities to Disasters, agreed by 168 Governments in Kobe, Hyogo, Japan in 2005 to facilitate a systematic rather than project-based approach to adaptation to climate change.
-
Scale-up the use of existing disaster risk reduction tools that have proven to be effective in dealing with climate-related events that will be exacerbated by climate change. These include vulnerability and risk assessments, early warning systems, land-use planning and building code regulation, and institutional and legal capacities.
-
Ensure adaptation to climate change and disaster risk reduction are integrated into development planning in all sectors. Establish inter-ministerial committees and national platforms for risk reduction to ensure inter-sectorial, multistakeholder coordination.
-
Improve capacities and services for knowledge transfer from science to practice and application to bridge gaps in risk management in climate-sensitive sectors.
ISDR secretariat focuses it efforts on there areas of action:
- Achieve recognition, understanding and specific policies at the international level on the synergies between reducing disaster risk and responding to climate change,
- Mobilize, guide and facilitate action at national and regional levels to integrate disaster reduction and climate change policies and practice, and
- Strengthen the capacities of the ISDR system and secretariat to support the integration of disaster reduction and climate change by all actors.
Partners can support these efforts through participation in the ISDR Working Group on Climate Change and Disaster Risk Reduction.
