“The Red List of Ecosystems includes current ecosystem maps, past ecosystem maps, historic ecosystem maps, and future projections. This information is very useful for deciding on strategies in each place for example for restoration and adaptation plans.” – Marcos Valderrábano, IUCN

After setting the stage by Verónica Ruiz, Programme Manager Climate and Disaster Resilience at IUCN and coordinator of the NAbSA programme, Marcos Valderrábano started the webinar by introducing the Lista Roja de Ecosistemas (RLE), a global standard for assessing ecosystems’ risk of collapse. The RLE does not set priorities but rather helps to inform them. The assessment process begins with defining the ecosystem’s structure and function, followed by evaluating trends using five criteria (A-E). The risk categories mirror those of the Red List of Threatened Species, from Least Concern to Critically Endangered, with ecosystem collapse as the ultimate threat. The IUCN Global Ecosystem Typology is used to organize ecosystems into a hierarchical structure with six levels, including realms, biomes, and ecosystem functional groups.

Marcos highlighted the importance of using localized data, demonstrated by mangrove assessments differing on the global and national scale. The RLE aids in national priority planning, protected area planning, and impact mitigation, and is integrated into national legislation for restoration, development planning, and adaptive management. It also supports reporting on global objectives, though local data is crucial for practical application.

Abordar amenazas específicas es clave para el éxito de la restauración y la adaptación. El marco contribuye a la restauración de ecosistemas y la adaptación climática proporcionando mapas de ecosistemas actuales, pasados y futuros para orientar las iniciativas. Al evaluar la resiliencia de los ecosistemas a lo largo del tiempo, se puede hacer seguimiento del progreso con indicadores específicos. La colaboración entre expertos de diferentes campos es esencial para recopilar e interpretar datos, lo que convierte a la Lista Roja de Ecosistemas en una herramienta crucial para la formulación de políticas y las intervenciones sobre el terreno.

“When we obtain the participatory maps, it’s to identify the uses for men and women and to help understand the use of the land around the villages, which brings out the ecosystem services.” – Chloé L’Ecuyer-Sauvageau, FproF

Caroline Mailloux introduced the Femmes Pro-Forêts (FproF) program, a three-year initiative in partnership with the Canadian Research Chair in Ecological Economics (CRCEE) and collaboration with Habitat, WASCL, EQUITAS. The program targets climate change adaptation for vulnerable women and their families in the Parc National du Moyen-Bafing, Guinea’s second-largest park and a critical biodiversity hotspot. The program’s objectives include promoting nature-based solutions to support biodiversity and enhancing the economic opportunities for women through these solutions. It also aims to ensure inclusive governance for the park’s biodiversity, prioritizing the adaptation needs of women.

Anne-Sophie Lessard discussed the use of spatial data to map biodiversity and ecosystem services within the project FproF. She highlighted the integration of local knowledge with satellite and GPS data to prioritize areas for reforestation and biodiversity conservation. The project developed a land-use classification to better address specific conservation needs.

Chloé L’Ecuyer-Sauvageau emphasized participatory mapping with local communities as a key tool for building trust and incorporating public values and knowledge into decision-making. This approach was used in 15 villages, considering gender-specific land use and the ecosystem services vital to community activities.

“When we map the evolution of mangroves, we need above all to identify and analyse the factors causing mangrove degradation. Because before setting up restoration strategies, we need to know the factors that are linked to this degradation – natural factors and anthropogenic factors.” – Dr El Hadji Sow, SEDAD

Dr El Hadji Sow presented the SEDAD (Solutions écosystémiques d’adaptation durable) project, which focuses on preserving and restoring mangrove ecosystems in Senegal and Gambia. The project aims to contribute to the preservation and restoration of the mangrove ecosystem, through the implementation of nature-based solutions in four Marine Protected Areas (MPAs): two in Senegal and two in Gambia. The primary goals include assessing current mangrove areas, developing and implementing plans to rehabilitate degraded mangroves, strengthening the technical and operational capacities of local stakeholders, and improving the living conditions of nearby communities.

Key tasks of the SEDAD project involve mapping and zoning of mangrove areas, assessing threats, and analysing the causes of degradation – both natural and human-induced. The project uses the Modelo DPSIR (Fuerza impulsora-Presión-Estado-Impacto-Respuesta) para evaluar los cambios ambientales y desarrollar estrategias de restauración. El resultado busca crear mecanismos de gobernanza sostenible para los manglares, garantizando que su conservación beneficie tanto al medio ambiente como a las poblaciones locales.

“Land cover maps are critical for local resource management, including conservation, restoration, reduced impact use, and financial mechanisms such as blue carbon.” – Trevor Gareth Jones, Natur’ELLES

Frédérique Thomas introduced the project Natur’ELLES, a collaborative initiative focused on the protection, conservation, and restoration of marine and coastal ecosystems in the Casamance and Siné Saloum regions. Centred around nine Marine Protected Areas (MPAs) and Indigenous and Community Conserved Areas (ICCAs), the project leverages the diverse expertise of all partners involved. By prioritizing the preservation and recovery of mangroves, Natur’ELLES plays a crucial role in climate change adaptation. The project emphasizes the active involvement of local women, empowering communities while enhancing environmental sustainability and resilience in these vital regions.

Yakhya Gueye elaborated on participatory mapping techniques in marine protected areas in Casamance and Siné Saloum, Senegal. He highlighted the role of traditional knowledge in environmental management, stressing the importance of community consent and participation in creating management plans. The process ensures that local knowledge is preserved and integrated into planning and conservation efforts, reflecting the specific practices and cultural expressions of the communities involved.

Trevor Gareth Jones, discussed the importance of land-cover mapping, which refers to the physical material on Earth’s surface, such as distinct mangrove classes. He emphasized that land-cover mapping is crucial for understanding landscape changes and modelling future scenarios. While distinct from land-use, which reflects human value, land-cover mapping is vital for local resource management, conservation, restoration, and financial mechanisms like blue carbon. Trevor further described his team’s work on inventorying, acquiring, and comparing land-cover maps for the Casamance and Sine Saloum Deltas. He noted the limitations of existing maps, such as their failure to capture the ecological variability within mangroves or subtle degradation.

Eduardo Carlucci presented the Metodología SAVi, a system-thinking approach to assess the impact of mangrove reforestation and conservation. This methodology integrates a qualitative system mapping process and a quantitative cost-benefit analysis of social, environmental, and economic indicators. Eduardo explained that SAVi assigns monetary values to externalities, such as job creation and health impacts, thus reducing project-related risks and empowering policymakers and local communities. This enables better planning and maximising investment effectiveness in reforestation and conservation projects.

The webinar’s discussions emphasized the importance of assessing ecosystems’ risks, using local data, and involving communities in restoration efforts. Techniques such as participatory mapping and land-cover analysis were highlighted as essential for understanding landscape changes and guiding conservation strategies. The discussions underscored the need for integrating traditional knowledge, gender considerations, and collaborative approaches to effectively plan and implement Nature-based Solution projects, ensuring resilience and sustainability in vulnerable regions.
