In the 2010s, global conditions including increasing temperatures, worsening income inequality, and insufficient access to social services catalyzed improved community building and localized solutions for climate-related challenges. This led to the conceptualization of resilience hubs—spaces that support residents and aid in distribution of resources before, during, and after a climate-related stressor.

Two U-M experts are investigating “informal green spaces” across Detroit. Such spaces, sometimes referred to pejoratively as ‘vacant lots,’ have emerged across the city in part because of cuts to public services. These areas now serve as homes for spontaneous vegetation, better known as weeds, which tend to thrive in such urban, resource-depleted environments.

Sarah Mills, senior project manager at the Center on Local, State, and Urban Policy, and Michael Craig, assistant professor at the School for Environment and Sustainability, have been selected for a grant from the U.S. Department of Energy Solar Energy Technologies Office.

Diverting urine away from municipal wastewater treatment plants and recycling the nutrient-rich liquid to make crop fertilizer would result in multiple environmental benefits when used at city scale, according to a new UM-led study. Researchers found that urine diversion and recycling led to significant reductions in greenhouse gas emissions, energy use, freshwater consumption and the potential to fuel algal blooms in lakes and other water bodies.

Methane is the primary component of natural gas, a greenhouse gas with 34 times the global warming potential of carbon dioxide. More than one percent of methane in the U.S. supply chain escapes into the atmosphere, much of which is caused by degraded pipes and loose-fitting components during distribution of natural gas. Ford School professor Catherine Hausman’s research has been cited as the primary influence of a law that passed in Washington state to address the problem.

Some Detroiters spend up to 30% of their monthly income on home energy bills, a sky-high rate that places the city among the Top 10 nationally in a category that researchers call household energy burden. The COVID-19 pandemic has only worsened the situation, adding financial challenges that make it increasingly difficult for many low- and moderate-income residents to pay their utility bills.
