The private sector dominates biotechnology research in industrialized countries, but there are major market failures in developing countries in accessing the new tools and technologies. The public sector, national and international, will have to play a major role in filling this gap. This paper provides an overview of options that countries of different sizes and capacities can employ to gain access to the research tools and technologies that they need to address issues of relevance to poor producers and consumers.

Water is scarce and pivotal for the Sahel, not only for increasing the productivity for millions of small-scale farmers but also for countering loss of arable land resulting from erosion and warming temperatures. A major barrier to the use of water in the Sahel is the lack of infrastructure and technologies – 45 percent of the population do not have access to water, and only 2 percent of arable land is irrigated (OECD, 2022).

There are many ways to help bring good ideas to life. Nesta works to uncover, develop and test, new ways of supporting innovation from across sectors and around the world. These techniques, tools and processes are collectively known as innovation methods.

Featured in this compendium are just some of the innovation methods we have explored over the last decade. Some, like seed accelerator programmes, we have invested in and studied. Others, like challenge prizes, standards of evidence or public sector labs, we have developed and helped to spread around the world.
