Some ten million people worldwide are displaced or resettled every year, due to development projects, such as the construction of dams, irrigation schemes, urban development, transport, conservation or mining projects. The results have usually been very negative for most of those people who have to move, as well as for other people in the area, such as host populations. People are often left socially and institutionally disrupted and economically worse-off, with the environment also suffering as a result of the introduction of infrastructure and increased crowding in the areas to which people had to move. The contributors to this volume argue that there is a complexity, and a tension, inherent in trying to reconcile enforced displacement of people with the subsequent creation of a socio-economically viable and sustainable environment. Only when these are squarely confronted, will it be possible to adequately deal with the problems and to improve resettlement policies.
