A grassroots citizens group in Peru stops a multinational firm from digging a mine in the middle of town. The research director of a think tank in Ghana helps convince the government to establish a national AIDS commission. An international NGO plays a key role in getting funding for climate-change adaptation included in a bill passed by the US Congress. All three are cases of the practice of policy advocacy. Confronting Power draws on these and other cases to illustrate a practical, comprehensive framework for planning, implementing, and evaluating policy advocacy.
