Abstract: This study explores the Land Use Land Cover Change (LULC) of oil industry on environment and local communities in Melut County located in Upper Nile State in South Sudan; as well as engaging the stakeholders in oil sectors to adopt the best techniques of sustainable oil exploration and production in the area. This research is based on remote sensing imageries collected for 2000 and 2018. The satellite imageries data were collected from Landsat-5 TM and Landsat-8 ETM+ for the two points. These satellite imageries were used to reach inaccessible areas in the Area. ENVI 5.1 software was used to analyze the satellite imageries. The results reveal tremendously significant environmental degradation as a result of land use changes over time that leads to deterioration of the livelihoods of the oil producing communities in Melut County. The main contributions to LULC were from exploration and production activities such as drilling, and oil processing. Produced water and oil well pads were the major catastrophes that lead to destruction of croplands, damage of vegetation cover, and contamination of surface and ground water in the area. There are inadequate social services in the areas around oil fields; hence, the areas are characterized by poverty, lack of access to resources, unimproved social amenities and vulnerability to the poor unhealthy conditions in the oil environment. Furthermore, the government should regulate the oil industry by scrutinizing any environmental violation, and heavily fine the non-complying individuals and companies.

Abstract: This research work exposes the results of our study about the cartographic and the qualitative estimation of the hydric erosion of the watershed of talangaï (Brazzaville) following the PAP/RAC approach, tele detection’s data and the geographical information system in order to elaborate thematic cards by enlightening erosion phenomenon. In this watershed of talangaï, this phenomenon of erosion became recurrent and causes more and more spectacular and worrings. As a matter of fact, except climatic aspects of the study zone, this watershed is characterized by a large irregularity of precipitations, of steep slope, and a weak vegetable coverage; which renders it very vulnerable to the erosion. Thus, after the analysis and the treatment of collected data, from the geographical information system (GIS), the study shows that 65% of zone of study present a weak and average erodibility and 35% of a high and the highest erodibility. Likewise, the descriptive cartography of different forms of erosions shows that ravine surface and the erosion in table-cloth are the most current. Also, the consolidated card of erosion states shows in a qualitative way that soil loss in the zone of study is in relationship with its geomorphology. In short, after combining different cards of principle erosive states, a synthesis has been done producing the consolidated card of these states (Integration approach). All these unfavorable conditions; slopes; geomorphology; erodibility; friability of soils, vegetal covert …), triggering of the catastrophe about erosive phenomenon are fulfilled. Thus, the obtained results allow to identify zones which are the most concerned, and the most vulnerable to hydric erosions.
