This document outlines an evidence-based advocacy strategic plan and discusses why advocacy is done and the roles of an advocate. Advocacy is done to influence decision-makers and address the causes of poverty through defending human rights, promoting justice, and engaging with officials to change policies and practices. Advocacy asks for new policies, revisions to unjust policies, enforcement of good policies, and blocking harmful policy changes. The roles of an advocate involve representing communities, empowering people, negotiating with decision-makers, lobbying for change, and mobilizing networks.
