Educational action research in development projects applies participative methods to include people with diverse backgrounds, experiencing learning collaboratively. In this article, I explore the learning activities, and their outcomes, unfolding in those settings. Based on project documents, 34 interviews with project staff and smallholder farmers, and participant observations for three months in Nepal, I analyse the action research and development project 'Strengthening Adaptive Farming in Bangladesh, India and Nepal' (SAF-BIN), and show how inclusive activities allow for critical reflection, individual experience, and dialogue. I find dialectics in this process of adjustment, such as resistant social and cultural arrangements that are activated. The inclusion of specific social groups, for example, goes along with exclusionary dynamics. This case illustrates that inclusion and action research can be conceptualised at least threefold: from a dialectical, institutional, and learning perspective. I conclude that action research in development provides a fruitful basis for learning, allows for legitimacy, and temporarily leads to social change at a micro-level, for better or worse.
