In cities around the world, there are vast networks of streams hidden below the ground surface. Through a process called daylighting, some cities are looking to rediscover these buried urban waterways.A new study provides a window into this hidden side of cities and tracks how daylighting affects the ecology and water quality of a stream in Norway.
Many believe over-regulation stifles innovation, but one regulation bucks this notion. New research suggests that companies subject to Extended Producer Responsibility (EPR) get more green patents certified compared to their unregulated peers.
Urban residents might like to think that city funds marked for equity go towards its most vulnerable members. A closer look at Chicagoan neighborhoods reveals that public spending often goes towards business interests instead.
In the 21st century, urbanization has become one of the most dominant forms of land use in the world. As natural ecosystems are converted to city landscapes, how do urban forests play a role for both birds and humans?
Globally, half of urban residents live in small cities, which may struggle to provide services efficiently and effectively. A recent study of waste management in the Czech Republic shows that if these small municipalities work together, they can gain significant benefits in the long-run.
Plastic consumption in high-income countries is on the rise despite increasing awareness of the plastic pollution problem. Recent research has revealed that consumers are driven to use more plastic because they don’t see the waste in their local environment. Instead, it is exported to low-income countries, conveniently taken out of sight and out of mind of the people most responsible.
Ridesharing companies like Uber and Lyft may enable people to forego car ownership, but are they good for the environment? A recent study suggests ridesharing, which has been commonly viewed as an innovative urban mobility solution, is perpetuating rather than solving cities’ carbon emissions problems.
Hard infrastructure, like sea walls and levees, prevent damage from smaller hazards but increase vulnerability to larger ones. The next generation of disaster prevention should focus on soft strategies like community preparedness.
The Chinese plastic industry is responsible for 25 percent of global plastic production. Despite the versatility and prevalence of plastics around the world, plastics have significant environmental drawbacks — a single plastic bottle produces three pounds of carbon dioxide and takes 450 years to decompose. How might China reduce these adverse environmental effects? One option the country is exploring is plastic waste recovery.
E-waste is frequently exported to developing countries and are recycled manually, polluting the air, soil and water and affecting workers and vulnerable communities. The Basel Convention is an international treaty created to counter that. However, enforcement and monitoring is lacking. Researchers and the Basel Action Network took matters into their own hands.
