"Most effective agriculture, environment and natural resource management projects tend to be those in which community members, development practitioners or agriculture experts jointly identify research or development parameters and participate in the decision-making process. In these projects, community engagement, consultation and participation occur from the very beginning and continue through the arc of the project. Here, the research and development process itself generates a situation of empowerment in which participants transform their view of reality enabling them to take effective action. This chapter delves deeper into participatory development communication, a branch of the development communication tree that takes a stand on empowerment as the key to sustainable development. The chapter reviews conceptual models associated with participatory communication, describes cases related to agriculture and natural resource management where the approach has been used to address challenges encountered by local communities and offers some thoughts for the future."
