Climate Change Adaptation Strategies in Coastal and Vulnerable Communities

Globally, coastal zones and other climate-vulnerable regions face sea-level rise, extreme weather, flooding, erosion, salinisation and socioeconomic disruption. Adaptation strategies are increasingly diverse, combining physical defences, ecosystem restoration, policy innovation and community-driven approaches. Structural measures such as seawalls, storm-surge barriers and managed retreat are complemented by ecosystem-based solutions including mangrove restoration, salt-marsh conservation and dune reinforcement. Non-structural measures encompass land-use planning, early-warning systems, insurance schemes and livelihood diversification. Crucially, stakeholder engagement and participatory governance underpin effective implementation at local scales. Social resilience is strengthened through capacity building, knowledge co-production and integration of indigenous and scientific knowledge. Cross-sectoral coordination and multi-scalar governance enable coherent policy frameworks, while monitoring and flexible management help to adjust interventions over time and avoid maladaptive outcomes. Case studies from deltaic megacities to small island states illustrate how adaptation portfolios must be tailored to ecological, cultural and economic contexts, emphasising the importance of equitable resource allocation and community ownership.

Climate Change Adaptation Strategies in Coastal and Vulnerable Communities publication trend

The graph below shows the total number of articles in climate change adaptation strategies in coastal and vulnerable communities across all publications each year (not limited to Nature Index journals).

Technical terms

Adaptive capacity: The ability of communities or social–ecological systems to adjust, learn and transform in response to climatic stress without compromising future options.

Ecosystem-based adaptation: The use of biodiversity and ecosystem services to help communities adapt to climate change impacts, such as restoring wetlands to reduce flood risk.

Hard engineering: Traditional structural interventions such as seawalls, breakwaters and surge barriers designed to provide physical protection against coastal hazards.

Stakeholder engagement: The process of involving diverse actors—government, local communities, experts—in decision-making to ensure adaptation measures are context-appropriate and socially legitimate.
