The South-east Europe and Black Sea region presents a fertile terrain for examin- ing recent international migration trends. A wide range of types of migration can be observed in this region: large-scale emigration in many countries, recent mass immigration in the case of Greece, return migration, internal migration, internal and external forced migration, irregular migration, brain drain etc. These migratory phenomena occur within the context of EU migration policies and EU accession for some countries. Yet within this shifting migration landscape of migrant stocks and flows, the fundamental economic geography of different wealth levels and work opportunities is what drives most migration, now as in the past. This paper sets the scene for the special issue in three ways: first, by defining the three key concepts of migration, transnationalism and development; second, by setting the geographical scene, with the aid of relevant statistics on the migration, development and remittance trends in the various countries of the region; and third, by summarizing the highlights of the papers in this issue of the journal, which range in their coverage from Ukraine and Moldova in the north, to Greece and Albania in the south.
