I started this blog to chronicle urban greening issues around the world and made it as far as Australia before the pandemic crisis struck.

For one day during the bushfires, Penrith, NSW was declared the hottest place on the planet.

Greening isn't always the most effective solution to pressing urban problems. But that doesn't mean the problems can't be solved.

Does the call for more experimentation mean that green infrastructure still needs more testing than grey infrastructure?

After the Millennium drought, Australian cities found other ways to irrigate parks, gardens, and landscapes, and so can we.

You don't just need expertise or experience to be an effective steward of urban trees. You need a network.

The catastrophic bushfires are a terrible reminder that adapting to climate change won't be enough. Here's how urban trees can help

American universities are still struggling to evaluate and reward practical, use-inspired, and community engaged research on solutions to...

Should arid cities plant more trees in a hotter and drier world? The science of “socioecohydrology” aims to find out.

At this site I'll be posting non-technical summaries of new projects in urban greening from my lab, my colleagues, and the people I'm meetin
