The markets and value chains approach has recently become fashionable in agricultural development interventions. So too have innovation platforms. This brief shows how innovation platforms can be a useful vehicle to promote market development. It is available in Chinese, English, Hindi, Thai and Vietnamese.

An innovation platform is a space for learning and change. It is a group of individuals (who often represent organizations) with different backgrounds and interests: farmers, traders, food processors, researchers, government officials etc. The members come together to diagnose problems, identify opportunities and find ways to achieve their goals. They may design and implement activities as a platform, or coordinate activities by individual members. This brief explains what innovation platforms are and how they work, and it describes some of their advantages and limitations.
