Coastal Mangroves in Africa provide critical services to coastal communities, including protection against climate change risks. These communities are particularly vulnerable due to their location, socio-economic conditions, and reliance on mangrove ecosystems.
The CoastMan project aims to create a decision support system (DSS) that helps restore and conserve these ecosystems. The project involves dynamic mapping of mangrove habitat loss risks, supporting local resilience, designing sustainable livelihood strategies, and developing the DSS. Ultimately, this effort will enhance the adaptive capacities of vulnerable coastal communities and promote climate action for mangrove restoration and conservation.

Key Risks

Risks to low-lying coastal socio-ecological systems: Navigate with ease through a user-friendly interface, designed for minimal learning curves.

Risks to food security: Effortlessly connect with existing tools and systems, making the transition as smooth as possible.

Risks to water security: Access your work anywhere, anytime, with cloud-based solutions that adapt to your mobile world.

Risks to terrestrial and ocean ecosystems: Access your work anywhere, anytime, with cloud-based solutions that adapt to your mobile world.

Approach to address the challenge

The overarching research question is “how the mangrove dependent, vulnerable coastal communities with limited capacity and resources can become more resilient to climate change and cope with the identified risks?

On the basis of the socio-ecological complexity of mangroves, we propose an approach of co-production and uptake of a novel MultiCriteria Decision Support System (DSS) that guides vulnerable groups and decision-makers in the process of knowledge-based decision-making for restoration and conservation of mangrove socioecological systems.


Mangroves thrive in the inter-tidal zones of tropical and subtropical coastlines. These saline-adapted forests form a unique wetland ecosystem at the interface of land and sea. Coastal Africa hosts 20% of the world’s mangroves, providing crucial protection against storms and coastal erosion. These ecosystems harbor rich biodiversity and store exceptionally high carbon levels compared to most forest types. However, they face significant threats from deforestation (driven by agriculture, logging, and human settlement) and climate change impacts (such as sea level rise, storms, and temperature changes). Ensuring the conservation of mangroves is essential for both coastal communities and the environment.
