Executive Summary
Coastal regions around the world face increasing threats from climate change, including sea-level rise, severe storms, coastal erosion, and the loss of livelihoods. Mangrove forests act as natural barriers that protect coastlines, stabilize soil, store carbon, and support biodiversity and fisheries. However, mangroves have been rapidly degraded due to urban expansion, aquaculture, pollution, and unsustainable harvesting. As a result, millions of people living in coastal zones are becoming increasingly vulnerable to climate impacts.
This project—Mangrove Regeneration for Coastal Climate Protection—aims to restore and expand degraded mangrove ecosystems through community-driven regeneration, scientific monitoring, and sustainable management practices. By regenerating mangroves in priority coastal regions, the project will strengthen natural defenses, enhance climate resilience, and improve livelihoods for coastal communities. The initiative will combine ecological restoration, awareness programs, community participation, and the use of GIS-based monitoring systems to ensure long-term sustainability. Over the span of three years, the project is expected to restore 300 hectares of mangrove forests, engage 1,500 community members, and develop a scalable model for coastal climate resilience.
Background and Rationale
Mangroves are among the world’s most productive ecosystems and play a vital role in climate adaptation and mitigation. They protect coastal communities from cyclones, storm surges, tsunamis, and tidal floods by acting as a natural buffer between land and sea. Their intricate root systems trap sediments, reduce erosion, and stabilize shorelines. Mangroves also serve as nurseries for many fish species, support coastal livelihoods, and store up to four times more carbon per hectare than most terrestrial forests.
Despite their importance, the world has lost nearly 35% of mangroves in the past three decades. Major drivers include aquaculture expansion, infrastructure development, unsustainable firewood harvesting, and the effects of pollution. In many regions, communities depend heavily on mangroves for fishing, fuel, and income, yet they are excluded from formal management systems. This increases pressure on the ecosystem and accelerates degradation.
Climate change further amplifies these threats. Rising sea levels, increasing temperatures, salinity shifts, and frequent storms make coastal zones more vulnerable. Without intervention, communities will face loss of land, reduced fish productivity, and increased exposure to hazards.
Given these challenges, mangrove restoration is recognized globally as a nature-based solution for climate resilience. It aligns strongly with Sustainable Development Goals, including SDG 13 (Climate Action), SDG 14 (Life Below Water), and SDG 15 (Life on Land). The project proposes an integrated approach combining ecological restoration, community stewardship, and scientific monitoring to protect coastlines and enhance climate resilience.
Project Objectives
The project aims to achieve the following key objectives:
- Restore and regenerate 300 hectares of degraded mangrove forests in selected coastal zones.
- Strengthen coastal climate resilience by reducing erosion, enhancing natural storm barriers, and improving shoreline stability.
- Improve community participation and capacity in mangrove conservation, restoration, and sustainable resource management.
- Enhance local livelihoods through sustainable mangrove-based enterprises such as ecotourism, crab farming, beekeeping, and fisheries support.
- Establish a GIS and drone-based monitoring system to track regeneration progress, measure biomass, and assess shoreline changes.
- Develop a long-term community-based mangrove management plan for continued protection and sustainable use.

- Baseline ecological surveys will be conducted to assess site conditions, hydrology, soil salinity, tidal patterns, and species suitability.
- The project will prioritize coastal regions with:
-
- Mangrove Restoration Activities
- Nursery Establishment
- Create community-led mangrove nurseries to propagate native species such as Rhizophora, Avicennia, Bruguiera, and Sonneratia.
- Train local people—especially women and youth—in seed collection, nursery management, and planting techniques.
- Plantation and Regeneration
- Plant seedlings and propagules during optimal tidal and climatic conditions.
- Use cluster planting, direct planting, and natural regeneration techniques depending on site characteristics.
- Restore hydrological flow by removing physical barriers and enhancing tidal connectivity.
- Protection of New Plantings
- Install bamboo fencing or eco-friendly barriers to prevent grazing and wave damage.
- Launch community-based patrolling to safeguard restored areas from exploitation.
- Nursery Establishment
- Community Engagement and Capacity Building
- The project places communities at the center of mangrove regeneration. Activities include:
- Awareness campaigns on mangrove benefits and climate protection
- Workshops on sustainable resource management
- Training programs for livelihood diversification
- Formation of Mangrove Management Committees (MMCs)
- Women-led conservation groups to enhance inclusion and leadership
- The project places communities at the center of mangrove regeneration. Activities include:
- Climate Resilience and Livelihood Enhancement
- Restored mangroves will protect communities from natural hazards while supporting climate-resilient livelihoods such as:
- Sustainable fishing
- Honey production through mangrove beekeeping
- Ecotourism, guided tours, and bird watching
- Crab and shrimp aquaculture
- Craft and value-added mangrove products
- These activities reduce pressure on mangrove forests while boosting household income.
- Restored mangroves will protect communities from natural hazards while supporting climate-resilient livelihoods such as:
Monitoring and Evaluation
A strong monitoring system will ensure transparency and effectiveness.
- Monitoring Tools:
- Evaluation Approach:
- Quarterly progress evaluations
- Annual ecological assessments
- Community feedback sessions
- Mid-term and final impact reviews
Monitoring data will guide adaptive management and corrective actions.

Project Timeline
The project will run for three years. During Year 1, activities will focus on baseline ecological surveys, community mobilization, nursery establishment, and initial planting efforts. In Year 2, large-scale plantation and hydrological restoration will continue, along with community training and development of climate-resilient livelihood models. Year 3 will emphasize monitoring, adaptive management, impact assessments, capacity building, and the development of long-term mangrove management plans. Throughout the project, GIS-based monitoring and community participation will remain central components.
