Goma is a millionaire city in eastern DRC facing natural and technological disasters. There is reason to say that its inhabitants live with fear in their stomachs despite their conservative spirit. Yet a strategic city since its creation, located between the Nyiragongo volcano in the north and Lake Kivu in the south with real constraints to its growth, the city also knows an urban anarchy because the rules of the art would be violated by a certain category of city-dwellers in certain places, such as on the shore of Lake Kivu, which moreover constitutes a zone of servitude. After confronting the reality on the ground with the regulations in terms of construction or town planning, it turned out that the urban habitat erected along the lake results from an urban anarchy legalized by the technical service in complicity with the other land actors on a high-risk area of tectonic origin capable of causing enormous damage such as the loss of human lives and material in the event of a tsunami. In view of this situation, the green belt, that is to say, revegetation was chosen as a new strategy for anticipating the danger of natural disaster.
