I read this article by Menno Schilthuizen, a Dutch evolutionary biologist and ecologist, about the evolution of animal and plant species taking place in cities. In cities, evolution is propelled by two forces: the known laws of ecology AND the social dynamics of human society. The article concludes that we...

Winter is here in the north—not the slightest allusion here to any famous TV series or any recent election, of course. And in the wintertime, life goes underground in a literal sense: tubers and roots reign while most of the aboveground parts of plants are dormant; animals hibernate or at...

In a previous contribution to The Nature of Cities (Faggi & Vidal 2016), we wrote about linear parks (LPs) as an interesting green space typology and discussed some strengths and threats of these multifunctional areas in Latin America. Other contributions (Tsur 2014, Das 2015, Maddox 2016) explained that LPs are...

In November 2016 there was a celebration in London: it had been 40 years since the idea of creating an Ecology Park in central London was first suggested. The event provided opportunities to share memories of those early days and to see how the concept has taken root and proliferated....

Often, city forest fragments and tree canopies are overlooked by city planners and developers as important bird habitat. More often than not, people only regard large patches as beneficial. The message from conservationists is that we want to avoid fragmentation and to conserve large forested areas. While this goal is...

“Why isn’t every city doing this?” Dave Vella asks as he intently massages a handful of succulent compost from the towering pile freshly deposited onto his vineyard’s gravel thoroughfare.

We attended the 22nd session of the United Nations Climate Conference (also called COP22) as “Observers” in the immediate aftermath of the U.S. 2016 presidential election. Since 1995, the COP has served as the annual UN climate conference, providing an opportunity to assess progress, negotiate agreements, and disseminate information regarding...

These contributions, originating around the world, were widely read, offer novel points of view, are somehow disruptive in a useful way, or combine these characteristics. Certainly, all 550+ TNOC essays and roundtables are great and worthwhile reads, but what follows will give you a...
