Determination of Organic Pollution Indicators in Lukaya River, Kinshasa, Democratic Republic of Congo.
This paper focused on the regression of vegetation cover in a few natural forest patches in Kinshasa. It is mainly based on the use of satellite imagery taken at different periods associated with field surveys to assess the changes in vegetation cover in different sites under study as well as causes arising from it. It aims to evaluate, characterize and map what was and what still remain of old forest patches; green and rich in plant and even animal species in order to hasten their recovery. The method is based on the detection of change on high-resolution images acquired at different dates over the same territory and to compare the results in order to extract change. The study allowed getting a picture that reflects the trends of the reality on the study sites. The results show that the decline in vegetation of selected natural sites is very real and has been of the order of 22.56 ha between 2000 and 2017, which corresponds to a deforestation of 41% of the area concerned. A few natural sites that carry a covered with trees or shrub are converted or transformed into dwelling land on which various buildings are built. However, the use of geomatics, including remote sensing and GIS tools turns valuable and well suited for space-time analysis of changes in different areas and particularly in environmental resources management.
