Food production worldwide is primarily carried out by smallholder farmers. Closing the gap between actual smallholder yield and those achievable through scientific research is vital to increasing the food availability and efficient use of inputs and natural resources. Multiple factors and constraints contribute to these production gaps, including uncoordinated linkages between education, research and extension. These linkages are often supply-driven and top-down, and unable to respond to the diversity of location-specific, locally-adaptive and multiple knowledge demands – as smallholders are a diverse group in terms of incomes, knowledge, perceptions and farming practices. In 2005, China Agricultural University (CAU) launched a pilot agricultural development project in partnership with Quzhou County in Hebei Province of China to work together to develop high-yielding technologies. In 2009, CAU professors and postgraduate students moved their research programs from the experimental station to the village, and rented a backyard, where they lived, worked and studied high-yielding technologies and responses from the farmers. Gradually, their backyard work attracted more farmers and encouraged their participation. The backyard thus became a science and technology dissemination platform in the local community. From then on, farmers, scientists and students referred to the project as the Science and Technology Backyard (STB). This publication was prepared as a case study report on the Science and Technology Backyard (STB).
