How does climate adaptation planning differ from mitigation in the context of geospatial risk?

• A. Adaptation reduces vulnerability to climate impacts (e.g., raised foundations), while mitigation reduces greenhouse gas emissions or exposure to hazards (e.g., levees, relocation) and both use geospatial data.
• B. Adaptation reduces emissions; mitigation reduces vulnerability.
• C. They are the same concept.
• D. Adaptation uses qualitative data; mitigation uses quantitative data.

Answer: (A)

Adaptation is about reducing vulnerability to climate impacts by adjusting systems and infrastructure to cope with projected changes. In geospatial risk planning, this means using maps and spatial analysis to identify where hazards will hit people and assets and then design actions to lessen harm, such as raised foundations, floodproofing, or smarter land-use decisions.

Mitigation, on the other hand, focuses on addressing the causes of climate change—primarily lowering greenhouse gas emissions—and, in some cases, reducing exposure to hazards as part of that effort (for example, through measures like levees or relocation of assets). Both approaches rely on geospatial data to map hazards, exposure, and vulnerability and to model future scenarios, but the objective is different: adaptation reduces the harm from climate impacts; mitigation reduces the drivers of those impacts and the resulting exposures.
