 Territorial markets are physical places where local supply and demand meet. They're the interface between consumers and the people and processes that provide food. Market markets are at the core of food systems and are crucial to ensure that healthy and diversified food is available and accessible. The Food and Nutrition Division has set up a methodology for mapping territorial markets. A quick and easy tool to support the improvements of food systems and help achieve healthy diets for all. Between June and August 2020, 17 territorial markets were mapped in Tanzania and the collected information referenced through a geospatial platform. The platform is part of FAO's hand-in-hand initiative, an evidence-based country-led and owned program to accelerate agricultural transformation and sustainable rural development. Collected data show that territorial markets ensure both the market outlet to producers and access to nutritious food for consumers. Tailor-made interventions for their improvement can produce large-scale impact. For example, specific investments can improve infrastructure and facilities in particular warehouses and cold storage. These would contribute to reduce food loss and improved food safety and availability. Or, working with financial institutions to develop specific instruments for food retailers can contribute to scaling up their business. Interventions targeting women are also very important. In Tanzania, women find it much more difficult to benefit from their work in territorial markets and this is reflected in the huge difference in earnings between men and women. Key to improving the inclusiveness of territorial markets is the development of business services specifically targeting women retailers. The mapping of territorial markets in Tanzania has already helped identify opportunities for investment, but it can do even more to move towards better livelihoods and sustainable food systems.
