LAPSSET: why a corridor project matters to mangroves
LAPSSET is a transport and port corridor centred on Lamu; Atlas measures how much mangrove lies near it.
LAPSSET stands for the Lamu Port, South Sudan and Ethiopia Transport corridor, a large infrastructure programme centred on a new deep-water port at Lamu. It plans roads, rail, pipelines, airports and a Special Economic Zone.
Why it matters for mangroves
- Port construction and dredging can remove or bury mangrove directly.
- Roads and causeways can block tides and starve mangrove of water.
- Growth in population and industry increases demand for wood and land.
- Ship traffic and pollution add stress.
What Atlas measures. For every mapped mangrove polygon Atlas finds the distance to the port area and development footprint and sums area into distance bands (≤2, 2–5, 5–10, 10–25, >25 km). The result: 18,676 ha (54%) of the mapped Lamu mangrove is within 10 km.
Using it. The AI analyst runs "what-if" scenarios on those bands, converting a chosen loss into hectares and a carbon range (see the Scenario Lab article).
