Storm Surge Reduction by Mangroves

Background

Flooding and wave energy from storm surges can damage infrastructure and harm inhabitants of coastal communities. Climate change and sea level rise have the potential to increase or intensify storm surges, which necessitate investment in coastal defenses and disaster risk reduction. Mangroves can reduce the effects of storm surges through attenuating waves and wind, making mangroves an important form of nature-based protection for coastal communities.

Reduction of Wind and Swell Waves by Mangroves

Background

Coastal ecosystems can mitigate the damage from extreme weather events like tropical storms and hurricanes. With human populations increasing in coastal areas, policymakers and stakeholders are interested in coastal ecosystems, like mangrove forests, as a nature-based form of coastal defense and resilience. This report aims to examine the potential for mangroves to reduce wind and swell waves in order to inform decision makers about the potential for mangroves to decrease the risks faced by coastal communities.

Participatory scenarios and spatial modelling to explore mangrove ecosystem services futures in Lamu, Kenya

Background

Lamu County, Kenya contains Kenya’s most extensive mangrove forests, which provide many vital ecosystem services (ES) for local communities (e.g., nutrition, building material, coastal protection, climate regulation). Land use and land cover change (LULCC), such as coastal development or infrastructure projects, threaten mangroves and their ES. Participatory scenario planning can help communities develop models of future LULCC grounded in both scientific evidence and local experience. Using these models in Lamu could inform future policy to preserve Lamu’s mangroves and balance country-level economic needs with local ES.

A meta-analysis of the ecological and economic outcomes of mangrove restoration

Background

Mangrove forests provide many ecosystem services to local and global communities that are both ecologically and economically important. Global mangrove loss and degradation decrease the provision of ecosystem services; however, mangrove restoration projects can reverse these effects and support critical ecosystem services. Therefore, syntheses of different restoration project outcomes are necessary to encourage global political support and investment into preserving mangroves and their vital ecosystem services.

Assessing the Environmental and Socioeconomic Impacts of Mangrove Loss in Indonesia: A Synthesis for Science-Based Policy

Background

Indonesia’s rate of mangrove loss has accelerated to about 40% over the past 30 years. Despite the government’s policies and investments for mitigating mangrove degradation, low seedling survival, and poor site suitability have impeded restoration progress. This study aims to review mangrove loss in Indonesia and assess the negative impacts of mangrove loss on carbon stocks, local livelihoods, and ecosystem benefits (e.g., fisheries, coastal protection, biodiversity).

Enhancing climate change mitigation in protected areas

Background

Protected areas (PAs) cover roughly 15–17% of the Earth’s land surface and contain a large share of remaining intact ecosystems, many of which store high densities of carbon. With global terrestrial ecosystems absorbing about 3 GtC yr⁻¹, understanding how much of this sink is associated with PAs is important for integrating biodiversity and climate strategies. However, evidence on PA effectiveness for carbon protection, across thousands of sites and multiple biomes, is dispersed and unevenly synthesized.

Current trends and future directions for integrating social values into mangrove restoration

Background

Different communication styles, governance, and social issues create barriers to successful mangrove forest restoration projects, and may hinder the ability to scale up projects to meet global restoration goals. Incorporating social values and stakeholder preferences into restoration projects can help identify best management practices, promote successful outcomes, and prevent distrust and inequality between restoration practitioners and stakeholders with different needs and perceptions of mangrove forests.

Tree species that ‘live slow, die older’ enhance tropical peat swamp restoration: Evidence from a systematic review

Background

Highly degraded forests often require active reforestation, which presents additional challenges with species selection for tree plantings. In tropical peat swamp forests, where harsh environmental conditions threaten seedling survival, various seedling and site treatments can enhance seedling survival and growth in restoration projects.
