The YieldWise Approach to Post-Harvest Loss Reduction: Creating Market-Driven Supply Chains to Support Sustained Technology Adoption

Excessively high levels of post-harvest loss often are a feature of agricultural systems dominated by small-holder farmers. However, this situation is something of a paradox, as technologies exist that have been shown in field demonstrations to substantially reduce post-harvest loss. What explains this paradox? Building on insights derived from the Rockefeller Foundation's YieldWise Initiative, this article proposes that while reducing post-harvest loss generally does require technology adoption by small-holder farmers, market-driven supply chains are essential to the sustained use of those technologies. We illustrate this approach using in-depth interview data collected from the YieldWise participants belonging to the Iringa Hope Cooperative in Tanzania. Data on the benefits and challenges of such an approach are provided from the perspective of the small-holder farmer. In addition, we model the economic benefits associated with this approach.
