The Activity Report brings together in a single document all the achievements of the Brazil Learning Initiative for a World without Poverty (WWP). In its almost four years of existence, the WWP has fulfilled its role to provide technical knowledge and encourage dialogue among policy makers, reaching more than 250,000 readers around the world, focusing on practical challenges. The report highlights the activities developed during this period in terms of publications, videos, webinars and events, and shows how the interinstitutional nature of the Initiative was essential to achieving these results.
