60 The proliferation of light arms and small calibre weapons within the civilian population constitutes one of the main offshoots of the long civil war experienced by Burundi. Matching estimates reckon on over 100,000 households which are said to be in possession of light arms and small calibre weapons. The Government, Civil Society and the development partners are aware of this problem and are of the view that the country cannot completely achieve lasting peace so long as these weapons remain in the hands of the population. It is in this context that the security committees were established in the Districts and the census hills in conformity with the provisions of Articles 277 to 279 of the 18 March 2005 Constitution relative to the National Security Council. Even Article 277 of the 2005 Constitution sets out the establishment of a Security Council. Article 24: The Right to a climate that is favourable for development All peoples shall have the right to a general satisfactory environment favourable to their development. The environment is the collection of natural elements which surround us as well as the elements of the human condition which touch or affect our lives, such as poverty, diseases, etc. The environment is a dynamic system defined by the physicochemical, biological and cultural interaction that takes place between man and other living beings, and all the elements of the locality, be they natural, transformed or created by man. Development is the process of transforming this environment for the well-being of the human group. Global development therefore implies the consumption of both natural and human resources ? while seeking to preserve, re-establish or improve their planning. Sustainable development is one that responds to present needs without compromizing the future of future generations to satisfy their own needs. This raises three major areas of reflection. Sustainable development is therefore the paradigm which is generally adopted for the integration of ecological and development policies. This concept could be considered as a matter of wealth and of well being. In searching for well-being, man may well adopt dangerous practices which could bring about the destruction of the ecosystems.
