Major social changes resulting from globalization, the increase in multicultural societies, and growing concerns for human rights, especially for women and girls, will affect all community practice in this century. Community-practice processes—organizing, planning, sustainable development, and progressive social change—are challenged by these trends and the ethical dilemmas they pose. Eight distinct models of community-practice intervention are described with examples from around the globe. The values and ethics that ground community-practice interventions are drawn from international and national literature. Model applications are identified for work with groups, urban and rural communities, organizations and coalitions, and in advocacy and leadership for social justice and human rights.
