Which adaptation strategy is likely to mitigate sea-level rise?

• A. Building sea defenses
• B. Deforesting coastal areas
• C. Increasing fossil fuel use
• D. Ignoring climate threats

Answer: (A)

Adaptation to rising seas focuses on reducing flood risk along coastlines. Building sea defenses creates barriers like seawalls, levees, and revetments that block or lessen the energy of waves and storm surges, keeping water from reaching inland areas. This directly lowers the vulnerability of people, infrastructure, and ecosystems to flooding and erosion, which is the core way to mitigate the immediate impacts of sea-level rise. Deforesting coastal areas removes natural protections like mangroves and dunes, which can increase erosion and flood risk. Increasing fossil fuel use worsens climate change and accelerates sea-level rise. Ignoring climate threats leaves communities exposed with no proactive protection. So the protective barrier approach is the most effective adaptation.
