Among the many lessons learned over my decades-long career in urban conservation is that iconography matters. Icons have proven to be powerful catalysts in the conservation arena, particularly in the urban context. Salmon, for example, are the quintessential representative of the natural world throughout the Pacific Northwest in both urban and...

In his essay published on The Nature of Cities in 2013, Keitaro Ito asked what seems at first to be a simple question: “Where will children learn about nature?” Yet it is actually an incredibly complex question, caught up in adult ideas that romanticize both childhood and nature. Children’s understanding...

Cities have long been known as hotspots for innovation. In the past, much of this could be attributed to cities being the centralised physical location of businesses, investors, consumers, markets, and places of learning, and as nodes for connecting with other people and cities around the world. Yet in the...

I like to simplify what constitutes urban nature in a given area. I therefore thought it might be interesting to provide an overview and to ask whether anything is missing, or erroneously included. This article expresses my view of the variety of forms that could be included under the “nature...

A wee garden in a windy city From a leafy suburb in the shadow of Table Mountain, I need not venture far to encounter a myriad of remarkable creatures employing clever survival strategies. Fighting, stalking, feigning, loving, dancing, stealing, and darting, biodiversity spills into and out of my garden. It...

Smart city technology is going beyond data-collecting sensors in streetlights and on garbage containers. It’s expanding to beaches and parks, creating a feedback loop that will allow local Barcelona Metropolitan Area officials to better manage public spaces. This technology adds a layer of big-data information that, ideally, will help cities...
