    Andean potato diversity conserved in the International Potato Center genebank helps develop agriculture in Uganda: the example of the variety 'Victoria'

    The International Potato Center (CIP) genebank conserves and facilitates access to highly diverse germplasm of potato, sweetpotato, and Andean roots and tubers as a global public good for food security. While it is generally understood that material from the CIP genebank has played an important role in the release of many CIP-related varieties grown by smallholder farmers in lower-income countries, the contribution has not been evaluated in quantitative terms. By applying the relative contribution of provenance based on pedigree data, we apportion the CIP genebank contribution of two released potato varieties: Pallay Poncho and Victoria. The estimated contribution of the CIP genebank to Pallay Poncho and Victoria is 35% and 72%, respectively. We then used an economic surplus approach to measure Victoria’s benefits in Uganda by attributing and valuing productivity gains. The gross benefit of Victoria in Uganda is estimated at USD $1.04 billion (2016 value), which exceeds the annual operating cost of the entire genebank over its lifetime. Seventy-two percent of the economic benefits corresponding to germplasm of Victoria are due to the CIP genebank contribution. Our findings demonstrate the magnitude of economic benefits generated by the use of conserved germplasm provided by the CIP genebank in crop improvement, which is only one of the several components of its total economic value. These results show that the availability of diverse germplasm is perhaps one of the most important elements in varietal development.

    Assessing the Impact of the CIP Genebank

    Preserving plant diversity is a critical objective of a genebank. Genebanks provide breeding programs with new and crucial traits that can be incorporated into crops. Future Food security relies on these traits, that can improve resilience to a changing environment and new pests.
  • The curious case of C-88: impacts of a potato variety on farmers in Yunnan, China
    Myrick, Stephanie; Pradel, Willy; Li, Canhui; Suarez, Victor; Hareau, Guy; Larochelle, Catherine; Norton, George W.; Alwang, Jeffrey R. (CABI, 2021-01-04)
    Background Limited analysis has been conducted of the role of agricultural research in promoting Chinese agricultural growth in less-favored areas. This paper analyzes how a particular potato variety generates benefits to producers and discusses how these benefits may have contributed to poverty reduction in Yunnan province. Cooperation 88 (C88) is a high-yielding, late blight-resistant variety that was developed through a partnership between the International Potato Center and Yunnan Normal University in Kunming, China. Methods Qualitative and quantitative methods are used to analyze determinants of adoption of C88, and to estimate impacts of adoption on producer well-being. A unique farm-household database is used to document the determinants of C88 adoption and disadoption. The quantitative assessment is supplemented with a qualitative analysis of the potato value chain to understand how seed availability and concern for processing attributes contributed to and eventually constrained diffusion. Market-level information was used in an economic surplus model to quantify the substantial economic impact of C88 over 20 years since its release. Results C88 spread rapidly in Yunnan following its release and was widely adopted by commercially oriented farmers. Disadoption began after 2010 with limited seed availability driving the shift toward newer varieties. Farmers, however, appreciate the ease of marketing, the 15% higher yields, and late-blight resistance associated with C88 suggesting that seed constraints are countervailing the economic benefits of the variety. Total impact on Yunnan potato farmers of the variety was estimated to be around $2.5 billion for the 1996-2015 period. Conclusions On per-person terms among C88 growing farm households, the economic advantage of the variety is likely to have contributed to poverty reduction. The aggregate impact of C88 diffusion occurred during a period of rapid poverty reduction in Yunnan and yield and disease-resistance benefits of C88 likely contributed to this reduction.
