In unusual circumstances such as in the former Yugoslavia, distinctions between refugees and IDPs may be further blurred by the changing of national borders. The Emergency Relief Coordinator and DHA have a clear responsibility for coordination of such assistance. Upon the return or resettlement of IDPs, or their diffusion into new communities, their 'targetability' begins to drop and the delivery of support programmes becomes progressively more difficult. Once IDPs' separate target group status is lost, attention tends to dwindle, yet conditions in their communities often remain worse than those which prevailed at the time of their original displacement. Quick post-return projects are followed by the more complex action of continuing development and growing government and community involvement.
Programming rightly begins to address the needs of their wider communities.
Since the fundamental socio-economic unit of reintegration is the household, attention to the specific needs of women is of key importance. Many times the displaced are never 'targetable'. Moving to other communities where they are only the minority, they blend in quickly and settle. Above all, they seek employment and services such as schools to which to send their children. A clash of paradigms is perhaps the most critical problem in facing the development challenges of communities with IDPs.
