Agri-food systems in developing and transitional countries are restructuring rapidly. Increasingly supermarkets have emerged in developing countries as important retailers, particularly for the high-value products meeting specific consumer demands related to production process and quality (Orden et al., 2004). In Latin America, supermarkets buy 2.5 times more produce from local farmers than the region exports to the rest of the world (Reardon and Berdegue, 2002). Supermarkets have also become a strong growth retail segment in Asia (Hu et al., 2004; Zhang, 2001) and Africa (Neven and Reardon, 2004; Weatherspoon and Reardon, 2003) and Central and Eastern Europe (Dries et al., 2004). The determinants, dynamics and outcomes of retail restructuring in developing and transitional countries are being discussed in detail in the first issue of the Global Issue Paper series of the Regoverning Markets Project (Vorley and Fox, 2004).
