Ecosystem Services and Ecological Processes
Mangroves protected villages and reduced death toll during Indian super cycloneBackgroundWhile protection against storm damage is discussed as an ecosystem service of mangroves, there is debate about whether there is sufficient evidence for these claims. Multiple studies on this topic use small sample sizes and have a lack of controls for confounding factors. However, quality research exists that effectively demonstrates mangroves’ ability to protect coastal communities from tropical storm surge. Thus, it is necessary that future studies focusing on mangroves’ protective capabilities from tropical storms follow higher research standards to effectively provide evidence for this ecosystem service.

Mangroves protect coastal economic activity from hurricanesBackgroundWith more frequent and severe weather events anticipated due to climate change, coastal communities are interested in practical coastal defense interventions to protect their public and private assets and prevent disruptions to economic activity from tropical storms. Studies have documented mangrove forests’ ability to reduce wave action, wind velocity, and storm surge, making mangroves a cost-effective form of coastal protection. Yet, the relationship between how large a mangrove belt must be to provide significant protection and how mangroves mitigate tropical storm effects and economic damages is still unknown.

Strong Climate Mitigation Potential of Rewetting Oil Palm Plantations on Tropical PeatlandsBackgroundTropical peatlands store vast quantities of carbon and therefore play a crucial role in global climate regulation. In Indonesia, extensive areas of peatland have been drained and converted to oil palm plantations and other agricultural uses. Drainage exposes peat to oxygen, accelerating decomposition and releasing large amounts of carbon dioxide into the atmosphere. Since degraded peatlands are estimated to contribute significantly to global greenhouse gas emissions, restoration strategies such as peatland rewetting have gained increasing attention as potential natural climate solutions.

Storm Surge Reduction by MangrovesBackgroundFlooding 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 MangrovesBackgroundCoastal 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, KenyaBackgroundLamu 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. Open access copy available |
Forest carbon in Amazonia: the unrecognized contribution of indigenous territories and protected natural areasBackgroundAmazonia stores an estimated 80–120 Pg of aboveground carbon, and changes in this stock have global climate implications. Indigenous territories (ITs) and protected natural areas (PNAs) together cover roughly one-third to one-half of the Amazon region, yet their specific contribution to maintaining forest carbon has often been overlooked in regional mitigation discussions. Quantifying their role is important for designing REDD+, climate finance, and land rights policies that reflect on-the-ground conservation performance. Open access copy available |
Ecosystem Services of Mangroves: A Systematic Review and Synthesis of Contemporary Scientific LiteratureBackgroundMangroves provide many ecosystem services, such as breeding grounds for aquatic organisms, sediment accumulation sites, coastal protection, nutrient cycling, and carbon sequestration. Beyond ecological functions, mangroves also sustain coastal livelihoods by providing natural resources and contributing to local economies. However, anthropogenic pressures from coastal development, agriculture, and aquaculture degrade mangrove ecosystems and the important ecosystem services they provide. Therefore, it is important to quantify and describe mangrove ecosystem services to better inform coastal policymakers and managers interested in mangrove conservation. Open access copy available |
