Montgomery, Alabama, touts itself as the birthplace of the U.S. Civil Rights Movement. But although Montgomery now embraces its history of bus boycotts and protest marches, it remains one of the most segregated U.S. cities, and still struggles with racial inequality. Today, Montgomery’s population is almost 60% Black. The poverty rate among Black residents is 30.8%, compared to 10.6% among white residents. The city’s infrastructure is deteriorating, and its tax base is shrinking. Cities with histories of segregation tend to suffer more from systemic racism that remains in the veins of their planning laws and policies. As a scholar of urban design and planning, I wanted to know more about how Montgomery’s history affected access to parks and public spaces there. My research explains how the city’s history still influences modern planning and creates unequal access to parks. Racial inequality is deeply embedded in MontgomeryR...

Many Americans think of power outages as infrequent inconveniences, but that’s quickly changing. Nationwide, major power outages have increased tenfold since 1980, largely because of an aging electrical grid and damage sustained from severe storms as the planet warms. At the same time, electricity demand is rising as the population grows and an increasing number of people use electricity to cool and heat their homes, cook their meals and power their cars. A growing number of Americans also rely on electricity-powered medical equipment, such as oxygen concentrators to help with breathing, lifts for movement and infusion pumps to deliver medications and fluids to their bodies. For older adults and others with health conditions, a loss of power may be more than an inconvenience. It can be life-threatening. We study environmental health, including the effects of extreme heat and storms on people. In a new study, we analyzed data from New York City and the surrounding area to...

Did you receive a mail-order package this week? Carriers in the U.S. shipped 64 packages for every American in 2022, so it’s quite possible. That commerce reflects the expansion of large-scale retail in recent decades, especially big-box chains like Walmart, Target, Best Buy and Home Depot that sell goods both in stores and online. This has led to the growth of distribution centers that fulfill these orders. While mail-order commerce is convenient, these centers also have harmful impacts, including traffic congestion and air and water pollution. I study environmental history, and I am part of a group of scholars examining the environmental impacts of big-box stores like Walmart, Target, REI and Bass Pro Shops. Sustainability is a hot topic in the retail sector, but my research on the history of Target – the sixth-largest retailer in the U.S. – shows how retail companies have largely escaped the kinds of environmental regulations that affect other sectors such...

The U.S. has a long record of extracting resources on Native lands and ignoring tribal opposition, but a decision by federal energy regulators to deny permits for seven proposed hydropower projects suggests that tide may be turning. As the U.S. shifts from fossil fuels to clean energy, developers are looking for sites to generate electricity from renewable sources. But in an unexpected move, the Federal Energy Regulatory Commission denied permits on Feb. 15, 2024, for seven proposed hydropower projects in Arizona and New Mexico. The reason: These projects were located within the Navajo Nation and were proposed without first consulting with the tribe. FERC said it was “establishing a new policy that the Commission will not issue preliminary permits for projects proposing to use Tribal lands if the Tribe on whose lands the project is to be located opposes the permit.” We are a cultural anthropologist and a water resource geographer who have studied tensions between...

New York City is poised to launch the first congestion pricing plan to reduce traffic in a major U.S. metropolitan area. Like many journeys in the Big Apple, this one has been punctuated by delays. Once the system starts up, however, it’s expected to significantly reduce gridlock in Manhattan and generate billions of dollars to improve public transit citywide. The basic idea is simple. To enter the Congestion Relief Zone, which covers Manhattan south of 60th Street, large trucks will pay $36, small trucks $24, passenger vehicles $15 and motorcycles $7.50. Ride-share vehicles and taxis will pay $2.50 and $1.25, respectively. Peak hours run from 5 a.m. to 9 p.m. on weekdays and 9 a.m. to 9 p.m. on weekends; overnight tolls are discounted by 75%. Evidence from cities around the world shows that charging motorists fees for driving into city centers during busy periods is a rarity in urban public policy: a measure that works and is cost-effective. Congestion pricing has succeed...

The U.S. Environmental Protection Agency has announced a new standard for protecting the public from fine particulate air pollution, known as PM2.5 because the particles are smaller than 2.5 millionths of a meter. These minute particles can penetrate deeply into the body and have been linked to many serious illnesses. The new rule sets an annual limit of 9 micrograms per cubic meter of air, down from the previous level of 12 micrograms. States will be required to meet this standard and to take it into consideration when they evaluate applications for permits for new stationary air pollution sources, such as electric power plants, factories and oil refineries. Under the Clean Air Act, the EPA is required to set air pollution standards at levels that protect public health. In the four articles that follow, scholars wrote about the many ways in which exposure to PM2.5 contributes to cardiovascular disease, lung cancer, other illnesses such as dementia, and premature deaths. 1. An...

The Biden administration has frozen pending decisions on permit applications to export liquefied natural gas, or LNG, to countries other than U.S. free trade partners. During this pause, which will last for up to 15 months, the administration has pledged to take a “hard look” at economic, environmental and national security issues associated with exporting LNG. Environmental advocates, who have expressed alarm over the rapid growth of U.S. LNG exports and their effects on Earth’s climate, praised this step. Critics, including energy companies and members of Congress, argue that it threatens European energy security and energy jobs in the U.S. Emily Grubert, associate professor of sustainable energy policy at the University of Notre Dame and a former official at the U.S. Department of Energy, explains why large-scale LNG exports raise complex questions for U.S. policymakers. Is the US a major LNG supplier? The U.S. is now the world’s largest LNG exporter...
