A commentary in the current issue of the journal Nature, co-written by Hillary Angelo, UC Santa Cruz assistant professor of sociology, argues that while big cities appear to be islands of sustainable living, issues of social equity and global impacts are missing from measures of cities' environmental friendliness.
The essay "Expand the Frontiers of Urban Sustainability" calls on mainstream urban research and policy practice to broaden conceptions of sustainability socially and spatially. They recommend incorporating more spatially extensive measures of sustainability into research and planning and bringing social equity into the heart of sustainability research, planning, and policy implementation.
Angelo, who joined UC Santa Cruz a year ago, wrote the piece with colleagues David Wachsmuth of McGill University and Daniel Aldana Cohen of the University of Pennsylvania. It is the lead commentary in Nature's opinion section and appears online and in the August 25 print edition.
The authors note that although cities were once seen as sustainability problems rather than solutions, this changed as concerns over suburban sprawl, shanty towns, and climate change grew. In recent years, awareness has grown that clustering people in energy-efficient buildings and walkable, shady neighborhoods can make cities more pleasant places to live and better for the global environment.
But true sustainability requires more than energy efficiency and walkability, they write. "Focusing on dense cities and their affluent areas ignores social movements and their advocacy for quality-of-life issues such as housing and commuting, which have direct ecological consequences."
Angelo and her co-authors call for expanding urban planning beyond individual neighborhoods and even municipalities to larger regions. "Sustainability research and policymaking should shift focus from city centers to urban regions and global networks of production, consumption and distribution," they suggest. In addition, "socially, policymakers should incorporate equity into every stage of the urban-policy process, from research to formulation to implementation."
