2019 Winner

Hungry cities: Inclusive food markets in Africa


The Inspire Challenge is an initiative to challenge partners, universities, and others to use CGIAR data to create innovative pilot projects that will scale. We look for novel approaches that democratize data-driven insights to inform local, national, regional, and global policies and applications in agriculture and food security in real time; helping people–especially smallholder farmers and producers–to lead happier and healthier lives.

This proposal was selected as a 2019 winner, with the team receiving 100,000 USD to put their ideas into practice. 

Food systems serving low-income urban consumers are notoriously hard to analyze. Nonetheless, these systems feed billions of consumers. To gain insight, the project proposes to analyze five years of commercial data on 17 fruit and vegetable crops from more than 20,000 farmers and 12,000 retailers and wholesale markets in metro Nairobi. Insights will support data-driven policy engagement, improved business decisions and further research on the role of fresh fruits and vegetables (FFV) in ameliorating nutrient deficiencies for low-income consumers.

Food systems serving low-income urban consumers contain multiple actors from fork to farm, commingle formal and traditional activities and generate partial or even contradictory data. Despite these limitations, these systems feed billions of low-income consumers. The diet poor urban consumers access, can afford and consume directly impacts their capacity to achieve their potential or fall victim to various forms of malnutrition and illness.

Metropolitan Nairobi, with 6.5 million inhabitants, provides a case in point. Low income residents face major iron and vitamin A deficiency in their diets. Most households cite availability and cost as the main constraints to FFV consumption. Improved access and affordability to nutritious fruits and vegetables could therefore play a role in reducing these deficiencies.

Twiga Foods, a Nairobi based start-up founded in 2014, offers a market-based solution through its innovative business-to-business (B2B) model. Twiga connects 20,836 farmers and 12,084 small-scale vendors using mobile technology to capture demand for 17 fruits and vegetables. In 2018, Twiga distributed a total of 16,787 tons of fruits and vegetables for a total turn-over of nearly US$6 million.

All all of Twiga’s transactions since 2014 have been captured using ICT tools, including production, distribution and sales data as well as reports on daily prices and volumes for the commodities they trade. The project proposes to use Twiga Foods data to assess how the Nairobi metropolitan area food system provides FFV to low-income consumers, identify inefficiencies in production and distribution and assist policy-makers to identify sustainable ways to provide healthy, safe and accessible food to growing urban populations in sub-Saharan Africa and beyond.
