Provincial and municipal authorities can play a key role in liaising with their national Government authorities and displacement-affected communities, as well as in the development and implementation of IDP-specific and community based programmes. Supporting local authorities in the development of community based programmes may be particularly appreciated when authorities must contend with the competing demands of other vulnerable sectors of the population who may feel their needs are being neglected. Such programmes should be based on disaggregated data on both IDPs and the host community, which includes their specific vulnerabilities, needs and coping mechanisms, and be participatory and inclusive. Community-based programmes can vary significantly depending on the context, but can include financial or in kind assistance to host families; community revitalisation programmes; or the expansion and strengthening of local infrastructures and services. Support to local authorities, through awareness raising and training, including on technical matters such as the conduct of consultative processes, data collection and programme design, should be areas for investment.
