Communication for Development (C4D) is a strategic process that promotes positive social change through consultation and participation. It uses a mix of communication tools to support programs in areas like health, education, and child protection. Key C4D strategies include advocacy, social mobilization, and behavior change communication. An effective C4D process involves communication analysis, strategy development, implementation, monitoring and evaluation. It aims to create enabling environments that give voice to marginalized groups and ensure the participation of children.
