Impacts of extreme heat are uneven across geographies and communities. People who live in micro-urban heat islands and who lack the capacity to cope with extreme heat are disproportionately vulnerable to heat-related health risks. Collaborative climate action planning processes should directly engage vulnerable communities in identifying neighborhoods with concentrated and...

One reason we should care about biodiversity is that it might be the solution to our environmental impact: after 3.8 billion years on planet Earth, Nature certainly has some sustainability and resilience lessons to teach us—that is, before it gets driven mostly to extinction. Will we care to listen? As...

Let’s face the facts. Despite laudable international initiatives for climate change mitigation and environmental preservation [i], major changes in Earth’s balances have been set in motion and we’re starting to experience their consequences: heat records; increased droughts; increased wildfire intensity and frequency; melting of landlocked ice; increased sea level and coastal...

India is experiencing rapid change as a consequence of 21st century urbanization. Making steady inroads into fertile farmlands, lush forests, thriving wetlands, and productive grasslands, urban expansion is steadily converting biodiverse lands in shades of blues and greens into swathes of gray concrete.

The current system of zoning and planning is wrongly fixated on maintaining state instead of preserving good patterns, and changing this fixation will be the key to making growth beneficial to all civic stakeholders. The most contentious issue in North American urbanism today is preservation. More than transportation, more than...

If planners and ecologists found more ways to work together, would cities look different? Would they be better? The idea of planning and designing urban spaces from an ecological perspective goes back to the very origins of the disciplines of ecology, planning, and design. Frederic Law Olmsted precipitated a landmark movement...

The New Urban Agenda, being adopted at Habitat III, requires a coherent and legible global urban scientific community to provide expertise to direct and assess progress on urban sustainability transformations. As we have commented in Nature’s special section on Habitat III, the urban research community is currently institutionally marginalized and...

I live in Stockholm, Sweden. I enjoy talking walks in the autumn, inhaling the scent from degrading debris, kicking around dead leaves, and gazing at the vivid colors. This fall, my baby daughter has often followed me on my walks. Her name is Viola, and she is 4 years old....

Georgetown, Guyana, is one of the world’s smallest capital cities, a mere six mi.2 according to its official boundaries.

What if urban resource management and conservation reflected not just the politics and science of the day, but were rooted in creation stories, place-name stories, and personal stories about the relationships people have with place?
