During the year 2005 many organizations took part in Poverty Zero, a campaign that aims to reach the United Nation’s Millennium Development Goals for 2015. Based on participant observation and open ended interviews, this paper describes the origins, development, and evaluation of Poverty Zero in Andalusia (Spain). It examines, by means of ethnography, how DNGOs (Development Nongovernmental Organizations) create social movement networks, and explores the limits and possibilities of their advocacy activities. The paper concludes that DNGOs tend to generate centralized social movements with reduced questioning of the global system. Nevertheless, as shown in the case of the Andalusian Alliance against Poverty, the more decentralized a movement, the deeper its transformational potential.
