The present volume offers for international discussion the firstmultidimensional comparative analysis cf two large groups of theworld’s displaced populations: resettlers uprooted by developmentand refugees fleeing military conflicts or natural calamities. Thevolume’s co-authors -academics and practitioners from bothfields -have joined up to explore common central issues: the condi-tion of being “displaced,” the risks of impoverishment and destitu-tion, the rights and entitlements of those uprooted, and, mostimportant, the means of reconstruction of their livelihoods.Refugee populations are generated by wars, civil conflicts,ethnic persecutions, or famines and other natural disasters. Thesepopulations often cross national borders and become internationalrefugees within a different country. Recently, however, as bordershave become less porous, many remain inside national borders andare defined as “internal refugees,” or internally displaced people.Involuntary resettlers are those uprooted by development-inducingprograms, such as infrastructure construction for industrial estates,dams and reservoirs, highways, ports ancL airports, and urban trans-portation networks. They typically remain inside national borders.Both groups are subsets of a wider category defined by the encom-passing concept of “displaced populations.”
