Laurent Lardeux, Retours d'exil. Ethnographie des rapatriements de refugies en Afrique central [Returns from exile: an study of refugee repatriation in Central Africa] Paris, EHESS, Cas de figure, 2015, 256 p.A stimulating book, this ethnographic study of refugee repatriation in Central Africa - or rather of refugee mobility and settlement in places of refuge, followed by resettlement in similar places in country of departure. Lardeux not only traces itineraries of refugees from Democratic Republic of Congo to Congo-Brazaville and Central Africa, then back to DRC; he attaches importance to relations that develop between trajectories, refugee careers and institutional policies, primarily those of UN Refugee Agency (UNHCR).Laurent Lardeux followed refugees and repatriated refugees from Congo basin from 2005 to 2010, literally moving alongside them through urban and rural spaces they lived in. As shown by a map at beginning of book, he covered distances between Kinshasa and Libreville, Yaounde, Bangui and Brazzaville three times, each journey lasting six to seven months; points that were either close or far for persons leaving RDC in early 2000s. The violence of war raging in that country at time forced as many as 2 million persons to flee; peak of exodus was in 2002. Lardeux judiciously chooses to start his fieldwork in 2005, year UNHCR's repatriation operation got underway.He first describes UNHCR policy in this connection, particularly how it changed over period studied. Under pressure from state governments, institution shifted its emphasis from receiving refugees in asylum zones or facilities and guiding and assisting them to promoting voluntary and assisting in that. Lardeux describes UNHCR practices, which began with encouragement and incentives, then switched to constraint as refugee aid in receiving country diminished, becoming aid for to and reception in departure country. While voluntary nature of repatriation is repeatedly asserted in UNHCR texts, that notion proved extremely malleable; border between free consent and forced was an indistinct one. The policies implemented did contain incentives, attractive conditions for voluntary return, but they also counted on negative incentives of outstaying one's welcome in country of exile, reductions in humanitarian aid and being poorly protected in reception zones. To underscore these ambiguities, author speaks of (in)voluntary repatriation.But what of trajectory and migrant career diversity? Forced displacement generates singular trajectories whose determinants are many. The author distinguishes between the time of exile and the time of return and provides a particularly rich description of practical determinants and types of social relationships that develop as well as their impact on migrants' trajectories.He first describes processes by which social and economic relations are established in exile. …
