the influence of coastal dynamics on mangrove forest south Conakry

The Guinean coastline has been undergoing change for several decades. South of Conakry, the rate at which the coastline is receding is a cause for concern. The aim of this study is to understand the evolution of the coastline and its impact on the mangrove forest. Coastal dynamics present environmental challenges rooted in both natural and human factors. The methodology employed is based on field surveys and mapping. Remote sensing and mapping software was used to process satellite imagery and produce maps. Areas of change resulting from human activities and coastal dynamics are evident in several locations. The average rate of coastal retreat is 11.34 m/year, with a 2 per cent decline in mangrove area. The number of trees lost is estimated at 33,661. The average advance of the coastline is 18.36 m/year, with an estimated progradation rate of 0.24 per cent, representing a gain of 4,614 trees. Thus, the results obtained show that coastal erosion and the decline in resources are a reality in the study area; these are exacerbated by human activities.
