Growing Heat Hazards from Climate Change and the Urban Heat Island Need to Be Integrated Across Siloed Urban Plans. Here’s How.
Sara Meerow, Tempe Ladd Keith, Tucson

Cities everywhere are getting hotter due to climate change and the urban heat island. Places like the Pacific Northwest in the United States, which historically was not concerned about extreme heat as a climate risk, have experienced unprecedented heatwaves in recent years (White et al. 2023). These deadly events, as...

In early 2018, the Assiniboine Park Conservancy, which is located in the western part of the city of Winnipeg in Manitoba, Canada, announced that they would be demolishing their conservatory in April, citing the end of the structure’s lifespan.

Can Neighborhoods Provide Breeding Habitat for Interior-Forest Specialist Birds? Yes
Mark Hostetler, Gainesville Natalie Pegg, Gainesville

Interior-forest specialist birds are reported to primarily require large, undisturbed forest areas in which to breed (Archer et al. 2019). Why do these species need interior forest conditions? Conservationists and research suggest that these species are vulnerable to the increased predators that are found in fragmented areas. Also, the abundance...

Ibrahim Wallee, Accra

The growing significance of sachet water in Ghana — the machine-sealed 500ml plastic bags of drinking water, known in local parlance as “pure water” — as a primary source of drinking water for households is important.

Urban Biodiversity Justice
Scott Kellogg, Albany

According to modernist philosophy, cities are “human only” spaces built by and for the exclusive use of homo sapiens ― clean, sterile, artifacts of human imagination that symbolize humanity’s separation from nature. Aside from cultivated garden plants and a handful of companion or work animals whose presence is tolerated, non-human...

The Tale of Lawns: The Story of Class, Deserts, and Potential
Alicja Wójcik, Brussels

What connects all upper-middle-class houses, public institutions’ buildings, stadiums, and golf fields? A hint: it is aesthetic, it is high-maintenance, and it is a prime example of a single species use. The answer is ― the lawn. The history of lawns goes back to the late Middle Ages, and is,...

Francois Mancebo, Paris

Sometimes — for a day, a week, or a month — Paris turns into the very kingdom of walkers. That is, during transit strikes, when subway trains and buses stop running. Millions of walkers flood the streets, as the Métro and bus network release the load of crowded bodies it...
