Executive summary

Atlas holds 195,557 mapped features and 37,971 observations in 28 datasets. The mapped mangrove canopy covers 151,840 ha in 10,419 polygons across 1 formation classes; Mangrove dominates with 100.0% of the area. The median patch is only 0.175 ha, while patches of 10 ha or more hold 96.2% of the area. 0 ha (0.0%) lies within 10 km of the LAPSSET development footprint.

Single mapping epoch (2019). Areas are geodesic hectares recalculated from geometry.

Recommendations

High 12 of 9 themes have no data yet
Atlas holds no records for: Salt Marsh, Coastal Forests, Blue Carbon, Restoration Sites, Protected Areas & Landscapes, Land Use & Land Cover, People & Settlements, Wildlife & Habitats, Fire & Climate, Farming & Livelihoods, Mining, Oil & Licences, Surveys & Field Data. Seagrass and salt marsh would come from UNEP-WCMC global datasets; carbon projects from the Verra and Gold Standard registries; community projects from partner programmes.
Action: Ingest the planned sources listed in the Source Catalogue, starting with Global Mangrove Watch, UNEP-WCMC seagrass and salt marsh, and the carbon registries.
High Licence terms to be confirmed for 13 datasets
Licence terms are being confirmed with the publisher. Atlas holds the data for scientific and internal use and shows the original attribution, but cannot grant bulk redistribution rights.
Action: Request written permission from WWF Kenya, KMFRI and KFS for redistribution and derivative products.
Medium Most polygons are very small, but most area sits in large stands
40.8% of the 10,419 mapped polygons are under 0.1 ha, yet patches of 10 ha or more hold 96.2% of all mangrove area. Management and monitoring effort should focus on the large stands, while the small-patch tail needs checking against satellite imagery.
Action: Prioritise field verification of large stands; review the sub-0.1 ha tail for mapping artefacts.
Low Net gain of mangrove since 1996
Global Mangrove Watch maps 122,084 ha of mangrove in Senegal in 1996 and 162,077 ha in 2025: a net gain of 39,992 ha (32.8%), about 1,379 ha per year. This is the net balance of total mapped area; gains and losses inside the country can cancel out, so real loss may be larger.

Methods & limits

Areas and lengths are recomputed on the WGS 84 ellipsoid; units are harmonised (ha, m, %, UTC). The mapping is a single 2019 epoch; the source publishes no licence; field plots are a sample; scenario figures are illustrative assumptions. Cite the original publishers listed above.
