Agriculture is key to sustainable development globally – particularly in countries where agriculture both accounts for most of the land use and provides a livelihood for most of the population. We map out a collaborative research agenda aimed at tackling the urgent but poorly understood issue of the role of farmer organisations in overcoming political barriers to sustainable and inclusive agricultural development, with particular attention to sub-Saharan African (SSA) countries. Building on a critical and collaborative dialogue between a diversity of small-scale farmer-led organisations, local activist groups, transnational civil society networks, and heterogeneous academic institutions, our agenda is organized around two key objectives: 1) understanding the conditions for, development of and outcomes from farmer-based political mobilisation in rural areas; and 2) strengthening participatory, action-oriented research capacity for critically engaged research on agrarian questions in SSA. The approach we advocate emphasises the scientific and societal benefits of combining theoretically informed crosscountry comparison of farmer-based rural social movements, with deepening of academic-civil society collaboration
