The world’s food systems face real and urgent challenges. These include climate change, nutrition insecurity, food safety, and unequal access to markets. Research has produced practical solutions to each of these that could benefit hundreds of millions of people. Too few are moved into widespread use.
For years, the development sector has flattered itself with pilots.
A new tool works in a controlled pilot, a crop variety performs well in a field trial, and a digital advisory service shows promise in early testing. Evidence is written up, a case study or experiment is published, and then comes the familiar refrain: now we need to “take it to scale”.
That is the moment the real difficulty begins.
Solutions do not spread simply because they are good. They move, or fail to move, through systems where scientific supply and demand for innovative solutions are frequently misaligned. Policy environments are not ready, financing is difficult to mobilise, demand is weak, and markets are not designed to carry promising ideas beyond their pilot phase.
