Land cover changes on the West-African coastline from the Saloum Delta (Senegal) to Rio Geba (Guinea-Bissau) between 1979 and 2015

Between the late 1970s and mid-2010s, wooded areas along the West African coastline from Senegal's Saloum Delta to Guinea-Bissau's Rio Geba expanded by 2% in mangroves and 3.5% on dry land, driven primarily by mangrove growth—particularly pronounced in recent decades. This net increase masks significant regressions offset by even greater progressions, with dynamic sectors outpacing stable ones. The study employed LANDSAT TM imagery and undirected classification techniques, enhanced by Principal Component Analysis to refine radiometric contrasts and reclassify misallocated pixels, revealing complex land cover dynamics over 36 years.
