A heat wave that pushed California’s power grid to the limit, and the water system failure in Jackson, Mississippi, are just two examples.
Flood risks are rising as the climate warms. The risks are complex, as a levee or new roadway in one place can worsen flooding somewhere else.
Fatal road injuries are among the top 10 causes of death in Ghana.
The quality of asphalt binder — the glue that holds roads together — influences their condition. Binder made from Alberta bitumen is low in waxes and could extend pavement lifespan.
Tackling climate change is a budget priority, but will we see the major investment in cycling infrastructure and public transport that is one obvious solution?
Parks and refuges are important for conservation, but without connections, they’re like islands. Linking them by protecting land in between makes it possible for wildlife to move over bigger areas.
Tourism revenues account for almost 10% of Costa Rica’s gross domestic product. New research shows that charismatic wildlife is necessary but not sufficient to attract ecotourists.
London was rated 2021’s most congested city.
The presence of roads, even inside protected areas, may pose a significant threat to species.
We need to rapidly reduce global emissions before 2030. Developing hydrogen for low-emissions road transport won’t happen fast enough.
Alaska is warming faster than any other U.S. state, and that’s causing problems, a team of bridge engineers and social scientists explains. The infrastructure bill in Congress would offer some help.
Short fixes won’t last.
Two urban policy experts explain why taking down highways that have isolated low-income and minority neighborhoods for decades is an important part of the pending infrastructure bill.
The lasting problems of infrastructure aren’t of need or construction, but of overbuilding, delayed costs and the challenges of thinking ahead.
The Tongass National Forest in Alaska, a focus of political battles over old-growth logging and road-building in forests for decades, has received new protection from the Biden administration.
Sat-navs could one day warn motorists when they drive through high-risk areas.
Government investment in roads, railroads and other public services has always involved social programming, both for good and for ill.
Governments must ensure that transport infrastructure is developed with the ability to cope with current and future climatic shifts.
