This study is the result of investigating the land use/cover surrounding Conakry city and its two neighboring cities from the past to the present periods which are herein after referred to as this “region” and the impact of numerous changes during that time. These changes have become a major concern for the Guinean government and scientific community. Using map interpretation with integration of remote sensing, GIS technology and a GIS method we investigated the land use/cover and a population dynamism model with the aims of promoting a sustainable recovery and future judicious utilization. We found out that these three cities are on the verge of being unified, as a result of the expansion of urban residential areas and the changing economic realities causing significant influences on this land use/cover change. The pattern of land cover 59 years ago presented a landscape relatively pristine, while that in the present period presents a landscape that is markedly in a degrading decline. During the past 59 years, land use/cover has been influenced by key factors that revolve around socio-economic development, climatic patterns, topography manipulation, and policy implementation influences. The level of degradation of the land use/cover has increased and will oblige the political, scientific and local communities to take note of the environmental changes and set up urgent, rigorous and coherent policies for the rational development and management of the land use/cover resources of this region. That can be part of a model for other countries to reclaim the past sustainable environment
