The coastal environments are highly coveted for their tourist and economic interests and constitute fragile ecosystems, sensitive to human’s actions: Pollution, artificialization, drying up, industrialization, urbanization, etc. shipbuilding has often contributed to aggravating the phenomena of erosion and retreat of coastlines. The heightening of coastal of Lake Kivu creates many pressures, particularly in the south basin. This southern basin of Lake Kivu is coveted by housing, hotels and churches, and is at the crossroads of commercial activities that alter them more and more. Out of a total of 19.14km of study, the occupied area is 11.07km with a high concentration of dwellings between the National Coffee Office (Bagira) and LABAOTE (see map). All these anthropogenic actions are source of pollution and destruction of the ecosystem of Lake Kivu in general and its littoral in particular. To remedy this, this article proposes to start the sectoral relocation of the occupants of the southern basin of Lake Kivu. Failing this, transitional strategies consisting of setting up a waste management network, delimiting the public domain, etc. are recommended for this purpose.

States in the South are no longer able to fulfill their redistributive function, that is to say to provide for the socio-economic needs of their population. In this context, the rural and urban populations of these countries are obliged to develop new forms of solidarity and mutual assistance in order to find solutions to the problems they are confronted with. Although the use of this notion is recent as elsewhere in Francophone Africa, it nevertheless relies on the organization of inherited practices of volunteering and adherence to collective work very old Twenty years ago, the Kabare chiefdom developed savings and credit groups on the model of solidarity mutual. Farmers are grouped either according to the environment, the affinities and according to their activities are fixed an amount, the deadlines and the beneficiaries by rotation. Designed to provide basic financial services to their members, these endogenous initiatives operate in the informal sector and receive no external input in terms of funding and training. In addition, the difficulties of appropriation of these decentralized financing structures by the members constitute the blockages in the evolution and the perpetuation of the financial services. Added to this, the low membership rate of the members, the low contribution rate of low household income, the poor organization due to lack of expertise, the proliferation of savings and credit institutions, the overlap and competition caused by the current diversification of Village Savings and Loan Association.
