This document discusses land acquisition and rehabilitation for displaced people. It identifies two main categories of displaced people: those displaced abruptly due to disasters or conflicts, and those displaced through planned development projects for infrastructure, industry, or resource extraction. The most widespread effect of involuntary displacement is impoverishment, as people lose land, jobs, housing, and social networks. Effective rehabilitation programs aim to prevent impoverishment by restoring access to land, employment, housing, healthcare, nutrition, community assets, and social ties. The key is to internalize costs and involve displaced communities in participatory planning and implementation of rehabilitation packages.
