Climate Change Adaptation and Disaster Risk Reduction Integration
This domain tests whether you can link climate adaptation with disaster risk reduction without collapsing one into the other. You should distinguish adaptation from mitigation, recognise maladaptation and apply climate risk information to DRR decisions.
Core rules and concepts
- Climate change adaptation adjusts systems and practices to actual or expected climate impacts. Mitigation reduces greenhouse gas emissions. DRR addresses all hazards, including geological and technological ones, not only climate-related hazards.
- Integration means using climate projections and uncertainty in hazard assessment, land-use planning, infrastructure standards, early warning and social protection. It also means aligning national adaptation plans with DRR strategies.
- Maladaptation occurs when an intervention reduces one risk but increases vulnerability elsewhere, shifts risk to another group or locks in unsustainable dependence.
- No-regret and flexible options are useful under uncertainty. Ecosystem-based approaches, climate services and community participation can support both adaptation and DRR.
Worked example
A coastal community faces erosion and flooding. A seawall may protect one stretch but can accelerate erosion nearby and is costly to maintain. Mangrove restoration and setback rules reduce wave energy, support livelihoods and allow adjustment. The reasoning considers uncertainty, distributional effects and long-term maintenance. The mangrove option is not automatically best everywhere; it must fit the shoreline, tenure and ecology. The key is to test whether the intervention reduces risk without creating new exposure or excluding vulnerable groups.
Traps that cost marks
- Confusing adaptation with emissions mitigation.
- Treating DRR and climate adaptation as identical.
- Ignoring maladaptation and risk transfer.
- Using global climate scenarios without local downscaling or uncertainty notes.
- Assuming green infrastructure is always feasible or sufficient.
