Sustainable development comes from a development process which enhances peoples' capacity to create and consume wealth on a lasting basis. Sustainable development requires, among other things, a socio-economic, political and cultural environment which enables people to engage in and sustain the development process. The political system should provide stability to allow people to engage in production. Intra-ethnic conflicts, tribal wars not to mention social tensions, as well as denial of basic human rights, constrain efforts to promote sustainable development. The social relationships between individuals and communities can as well promote or constrain sustainable development.
