This chapter analyses two collective action cases in Canada: Group Environmental Farm Planning in Saskatchewan and the Beaver Hills Initiative in Alberta. In the first case, Saskatchewan producers act together to adopt Beneficial Management Practices (BMPs) by accessing risk assessment programmes that approach environmental protection collectively. The second case was launched in reaction to strong development pressures that threatened landscape and other environmental values. It involves various participants, who pool their knowledge and develop science-based strategies to preserve the area. Following a brief description of the case studies, the roles of participants, the factors affecting the outcome of collective action, and the role of government are discussed.
