As international agricultural research centers places greater emphasis on poverty reduction, a debate is underway whether higher priority should be given to research to “add value” to agricultural commodities through post-harvest innovations at the expense of the traditional emphasis given to agricultural production. In particular, post-harvest research is seen as a way of creating new markets for commodities that may be in surplus or are facing declining demand. In this paper we review the evidence on the economic benefits from past public investments in post-harvest research to increase value of two major food crops – potato and sweetpotato. For the review we draw upon the experiences of two research institutions: first for the United States public research system during the early 20th Century and then for the International Potato Center (CIP) since its post-harvest research program began in 1975. Most of the evidence from both the U.S. and CIP’s experiences strongly suggests that public sector investment in generating value-enhancing technologies for potato and sweetpotato has been characterized by a low rate of return. New product development is a particularly risky endeavor. Implications for investment by international agricultural research centers in value-enhancing agricultural research are discussed.
Research and publications on the potato crop have burgeoned since the first edition of this book was published in 1978. However, the warm reception of the first edition suggested that it had a useful part to play in promoting the scientific basis for understanding and improving the yield and quality of the crop. Since the first edition was out of print and a second reprint would not have taken into account the contributions made by research over the intervening years, it became obvious that a complete revision was necessary. There was, in particular, a need to take account of the rapid extension of interest in the crop into climates and farming systems with which it has not been traditionally associa,ted. Those involved with the crop will be sadly aware that a number of contributors to the first edition are no longer with us. Their contribution to our knowledge of the crop will however be a permanent legacy of their achievement. I would like to thank all those who have contributed to the book for their willingness to cooperate in the difficult task of bringing their particular subject up to date. This is even more noteworthy for the pressure of time appears to be almost an order of magnitude higher than it was when the first edition was tackled.

During the International Year of the Potato, celebrated in 2008, FAO and the International Potato Center helped forge partnerships worldwide to address critical aspects of sustainable potato production. This technical guide collates that experience to review technical, socio-economic, policy and institutional factors that currently constrain increased potato production and productivity in tropical and sub-tropical countries. it presents Good Agriculture Practices relevant to potato production, and indicators and recommendations for action in key areas. It outlines a new policy and research agenda for the potato subsector that aims at making a real contribution to the eradication of hunger and poverty.
