In many parts of the world today, soil erosion is the major obstacle to mankind's future well-being. Combined with flooding, soil erosion is responsible for almost half of all deaths from natural disasters over the last 50 years, and almost a third of all economic losses worldwide. To prevent the Bubolese population from these disasters, it is necessary to identify the causes of recurrent flooding and erosion in the Municipality of Mususa in the City of Butembo and to propose solutions for the efficient prevention of these phenomena. Thanks to an approach based on a combination of several methods, notably documentation, fieldwork and the use of 'open street map' satellite data and the reference RGC database in the Democratic Republic of the Congo (DRC), flood-prone areas were identified and located around the Kimemi River. Whereas eroded areas are located along the Wayimiria River. Hence, after fieldwork, flooding in the Municipality of Mususa is the result of precipitation and inappropriate urbanization. Strategies to combat this phenomenon include (a) public awareness campaigns and (b) the use of tanks to store rainwater. In addition, erosion is caused by the regular mining of sand in the riverbed by the riverside population, and also partly by the nature of the soil. For this reason, the use of plants such as bamboo and public awareness campaigns would be the best solutions to these problems. Considering the urgency and gravity of the situation, the political and administrative authorities must get involved to stop these disasters, because prevention is better than cure.
