Benchmarking food crop markets in Southern Africa: the case of potatoes and potato products 1961-2010.

摘要

Pressures and opportunities in food systems across Southern Africa have generated renewed interest in potatoes both as a food crop and a source of income in recent years. With populations growing at over 2.0%/year in several countries and urban consumers often eager to diversify their diets, new markets are also opening up. Given these trends, growers, traders and governments are seeking out new ways to capitalize on these developments. This paper examines the evolution of growth rates in potato production, utilization and trade in Southern Africa over nearly the last half century using FAO annual secondary data. After highlighting the different roles that potatoes have played in crop diversification across the sub-region, the paper identifies some key issues for future research as well as some opportunities for industry both large and small.
