Rather, what is needed is a set of marketing policies and institutions that connect farmers to markets by reducing their marketing costs and risks (IFPRI, 2007). Similarly, this analysis strongly confirms the importance of better market integration and investment in rural infrastructure to help reduce transport and energy costs thereby better transmitting the opportunities created by market opening to those regions. Today, food and other agricultural products are sourced globally as much as manufactured products and the expanding markets for agro-food products are opening up new opportunities for developing countries (see Box 4). Participation in regional or global agro-food value chains allows developing country producers to overcome the limits imposed by their small domestic markets. It provides them access to more vibrant markets, allowing them to upgrade their production processes and improve the quality and value-added of their products. Although the strong growth performance of recent years has been mainly attributed to Zambia’s booming mining sector (copper is the country’s single largest foreign exchange earner), agriculture is the most dynamic component of Zambia’s export economy and is the main driver of export diversification.
