Mangrove Restoration
Safeguards for climate-resilient ecosystems and communities
Protecting and restoring mangrove ecosystems proves a powerful tool for both environmental and social outcomes. But without adequate planning, these efforts can disrupt natural ecological functions, alter hydrological regimes, or increase erosion. This brief explores how mangrove restoration initiatives can integrate social and environmental measures to prevent harm to ecosystems and communities.
Recommendations
-
Conduct rigorous environmental assessments and long-term monitoring, including environmental impact assessments, climate risk assessments, baseline surveys of connected ecosystems, and biodiversity monitoring that extends well beyond the typical 1-to-2-year post-project window.
-
Use sound ecological restoration practices: choose native, climate-resilient species suited to local conditions, assess propagule/seedling supply before establishing nurseries, develop post-harvest care and long-term monitoring plans, and build in adaptive measures to account for climate risks.
-
Ensure inclusive and equitable participation: meaningfully engage rightsholders, local and Indigenous Knowledge holders, and equity-deserving groups in planning and implementation, and conduct gender analyses to identify differentiated vulnerabilities and ensure benefits are fairly distributed.
-
Establish transparent governance and respect rights: develop clear data management plans, communicate with communities in accessible ways and languages, conduct tenure and access assessments, and uphold human rights, including free, prior, and informed consent.
Effective mangrove restoration requires more than simply planting seedlings: it demands rigorous scientific planning, inclusive community engagement, and strong governance frameworks.
Mangrove ecosystems protect coastlines, help combat erosion, and can sequester vast amounts of carbon. Culturally, they are also valued for their contributions to spiritual and social connections, livelihoods, and education. However, 20% to 35% of mangroves have been lost over the past 5 decades due to agriculture, aquaculture, urban development, and climate change.
In this context, protecting and restoring mangroves is increasingly a priority. However, without adequate planning, mangrove restoration efforts can disrupt natural ecological functions, alter hydrological regimes, or increase erosion. On the socio-economic side, a lack of stakeholder engagement and poor coordination and governance can lead to loss of livelihoods, conflict over tenure or customary access, exacerbation of gender inequalities, and increased vulnerability to climate change impacts.
Drawing on the Convention on Biological Diversity guidelines, this brief outlines a set of social and environmental safeguards that restoration projects should integrate to ensure their success. From conception through to long-term monitoring, these measures cover environmental impact assessment, harm prevention, inclusive participation, equitable access to benefits, transparent governance, and respect for human rights.
By foregrounding the social and governance dimensions that are often overlooked, the brief intends to complement existing technical mangrove restoration guidelines for policy-makers and practitioners seeking to plan and implement effective, inclusive coastal nature-based solutions for community resilience.
