The rapid transformation of agri-food value chains in Africa and other developing countries has important implications for economic growth and poverty reduction. Policy makers increasingly recognize this but there is a need for a better understanding of what value chain transformation entails and what the main policy options are. This paper provides an overview and analysis of different value chain models that have emerged in the past decades and reviews the literature on the main development implications. We discuss and categorize existing policy initiatives that aim to stimulate inclusive value chain development. Based on this review we identify lessons and implications for policy makers. In general these modern value chains have been significantly affected by changes in agricultural and food standards. Such standards are spreading rapidly and food production and trade are increasingly regulated through stringent public and private requirements on food quality and safety, and ethical and environmental aspects (Henson and Reardon 2005; Jaffee and Henson 2004). 1 Both public and private standards have become more stringent and more widespread. 2 Yet, the modernization of value chains, both domestically and internationally, has accelerated sharply during the past decades. Moreover, the growth has been strongest in where standards are most important, i.e. in the higher value productswhich includes fruits, vegetables, seafood, fish, meat and dairy products. For example, the shift towards high-value exports has been most dramatic in developing regions (Maertens and Swinnen 2015). In Asia and in Latin-America, high-value products increased from around 20% of agricultural exports in the 1980s to around 40%. The process is similar, albeit slower, in Africa. At the same time, (foreign) investment at various stages of these value chains has increased significantly. Increased investment has been triggered by several factors. The first reason is the wave of investment liberalizations in the past 20 years which have made it easier for FDI to flow in. The second reason is strong economic growth in emerging and developing countries, which has triggered increases in demand for higher quality products and, with growing urbanization as part of the economic development process, and increasing demand for retail and processed products in urban areas In combination, these developments have resulted in changes in the way agricultural value chains are organised with increasing levels of verticial coordination, upgrading of the supply base and increased dominance of large multinational food companies (McCullough, Pingali, and Stamoulis 2008; Swinnen and Maertens 2007). These processes have important implications for developing countries. Increased demand for high-value products and increasing prices in international food markets create opportunities for developing countries to realize economic growth through expanding and diversifying their agricultural exports. High-value agricultural exports entail an important potential for raising r...
