This document discusses participation in development. It defines participation as people's involvement in decision-making, program implementation, and benefits, as well as their role in evaluation. There are two main types of participation: instrumental participation focuses on project outcomes and sustainability, while transformative participation empowers communities to take independent action to improve their situation. The document also examines conceptual contexts around development, inclusion and exclusion, and criteria for classifying different levels of participation, from passive to self-mobilization. It explores how participation and citizenship are linked, with citizenship participation based on extending participation rights.
