Application of Digital Mapping (GIS) to the Study of Anthropic Impacts in the Environmental Problem in Northern Maritime Guinea

Geographic Information System

The coastal zone is a small area characterized by considerable linearity and significant human pressure. It is home to many environmental, economic and human issues. In recent years, the coastline has been "maritimised" by a growing concentration of uses in the coastal sea (Gourmelon and Robin, 2005). The need for a more dynamic and integrated approach to the coastal zone, through the land-sea interface, has been reflected since the 1970s by the international concept of Integrated Coastal Zone Management (ICZM), which expresses the need for acting collectively on the natural and anthropogenic processes likely to threaten the sustainable maintenance of the quality of the environment and activities (Cicin-Sain and Knecht, 1998). The prerequisite for effective management of this complex space involves a thorough knowledge of the processes that take place there and a conceptual approach to its operation through coastal geographic information systems (GIS). This study proposes a diagnosis on the evolution of the land use in the taking into account of the problems of integrated management during the last thirty years of 1987,2007 and 2017 in the zone of study (Boké- Boffa).
