The main objective of this survey is to examine the role of contractual arrangements between the value chain stakeholders on the development of technical knowledge on grain-legume crops. Developing grain-legumes both in cropping systems and in end-uses suffer from a knowledge gap among practitioners. This gap need to be fulfilled to increase grain-legume competitiveness. Hence, practitioners (or stakeholders) need to develop and exchange knowledge that they need for the running of the value chain based on legumes. This survey will allow understanding how the governance of grain-legume transactions between the stakeholders influences knowledge creation, exchange and thus collective learning in the value chains. This survey was conducted with stakeholders from various value chains on chickpea, on soyabean, on pea and fababean in ten European countries Danemark, France, Germany, Italy, Latvia, Lithuania, Netherlands, Portugal, Switzerland, and United Kingdom. The survey attached is the one used for chickpea. The questions addressed are the same for other crops. Thesurvey was organized within the H2020 LEGVALUE project.
