When we talk about specific foods in a food system, we are often talking about “value chains.” A value chain describes the process that takes a crop from the field to the supermarket shelf. It begins with the inputs that lie behind a farmer planting their crops and then extends through warehouses, transportation, processors, food manufacturers, wholesalers, exporters, supermarkets, street food vendors, and fast food restaurants. They all influence the way small-scale producers farm and market their produce.
And all these elements of the value chain have, in turn, been influenced by urbanization, population growth, and rising incomes in developing countries, which have transformed what people eat over the past twenty years. Diets are now more diverse with people eating more meat and processed food. These trends both drive and reflect changes in the way food is created, stored, shipped, processed, and sold, and change the risks borne by small scale producers and farmers.
This evidence synthesis looks at how small-scale producers engage with various elements of complex food systems. Does this engagement improve the welfare of farmers? Does it raise productivity? Does it improve the use of technology? What are the conditions under which small-scale food producers successfully achieve these goals?
