EMMANUEL PRATT is an urban designer creating a model of resident-driven community development in neighborhoods that have suffered the effects of long-term disinvestment. Pratt is co-founder and executive director of the Sweet Water Foundation (SWF), a nonprofit organization based on Chicago’s South Side that engages local residents in the cultivation and regeneration of social, environmental, and economic resources in their neighborhoods. Pratt’s holistic approach to community development—integrating agriculture, education, and design—is informing the work of organizations in other cities and demonstrating the power of using ecological systems as a guide for turning neglected urban neighborhoods into places of growth and vitality. Pratt is a recipient of the 2019 MacArthur Grant.
