Disaster Risk Reduction in an Unstable World

This policy brief by the International Institute for Sustainable Development examines the evolution and implementation of Disaster Risk Reduction (DRR), emphasizing the shift from emergency response to proactive risk management. It highlights the critical role of integrating DRR with climate change adaptation and the use of nature-based solutions, such as wetlands, to mitigate the impacts of increasingly frequent and intense weather-related disasters.

• Between 1970 and 2019, weather, climate, and water-related hazards caused more than two million deaths and resulted in losses totaling USD 3.64 trillion, with over 11,000 disasters attributed to these hazards.
• The disparity in outcomes between the 2010 earthquakes in Haiti and Chile demonstrates that while natural hazard severity cannot be controlled, the resulting destruction and loss of life can be managed through strict building codes, sound infrastructure investment, and enforcement capacity.
• Investment in disaster risk reduction is economically efficient; for instance, in Bangladesh, every USD 1 spent on flood protection infrastructure avoids USD 123 in damages and lowers the likelihood of floods from 20% to 4%.
• The Sendai Framework for Disaster Risk Reduction 2015-2030 shifted the international focus toward "disaster risk management" and expanded the scope of DRR to include anthropogenic hazards and environmental, technological, and biological risks.
• Integrating DRR and climate change adaptation helps avoid duplication of efforts. The Pacific region pioneered this through the Framework for Resilient Development in the Pacific (FRDP), which focuses on resilience, low-carbon development, and disaster preparedness.
• Healthy wetlands serve as critical natural infrastructure by absorbing excess rainfall to reduce flooding and releasing stored water to delay droughts. For example, wetlands on the US East Coast avoided over USD 625 million in damages during Hurricane Sandy in 2012.
• Effective DRR requires a combination of top-down institutional strategies and bottom-up community approaches, such as the use of WhatsApp for hourly updates in local languages in Zimbabwe and the distribution of reinforcement kits by the Mozambique Red Cross.
