Many voices. Greener cities. Better cities.
Andrew Clements

Andrew Clements

Fifteen years ago, Andrew Clements began researching bio-climatic architecture and particularly roof greening, initially for his own needs. Having purchased a 120-year old farmhouse in the mountains near Corinth, Greece, he searched to find a Greek-based green roofer and was dismayed to find that there were none. Undeterred, he set about discovering how such an endeavor might be accomplished. The challenge was to create a completely Mediterranean green roof, eco-roof, or living roof, as it is sometimes known, developed for the building challenges and climate peculiarities of the Mediterranean. After 6 years of R & D with the invaluable help of a small team of specialists (architects, civil engineers, geologists, meteorologists, eco-system specialists) the first Mediterranean roof greening approach was born in 2006. It was christened Oikosteges (pronounced eco – steg –gez), which is a compound of two ancient Greek words: 'Oiko', meaning 'related to the home', and from which the Latin 'eco' is sourced, and 'steges', meaning abode, roof over your head. Oikosteges offer the only real alternative to expensive and inappropriate roof gardens for Mediterranean countries. Oikosteges' mission is to recreate natural, bio-diverse Mediterranean ecosystems on any and all built structures in the cities and towns of the Mediterranean and in similar climates around the world, using a number of natural approaches informed by such concepts as ecological succession. These ecosystems require little or no maintenance and little or no irrigation once established. The ecosystems are feather lightweight so that they can be applied to virtually any built surface in this active seismic region. Now, Andrew holds two patents for Greek-appropriate green roofs. He is particularly interested in water-wise, natural, ecosystem development in hot cities such as Athens, as well as the challenges of working in a seismic region. Landmark projects include The Greek Treasury building in Constitution Square, Athens. In addition, the Oikosteges team established Green Roofs Greece, a not for profit organization, which currently boasts a Facebook membership of over 21,000, in order to share experiences and ideas with the worldwide networks of green roof activists.

Antiracist Environmental Leadership in a Virtual World
Cindy Thomashow, Seattle

Our graduate students are figuring out how to best “immerse” themselves in city spaces while staying safe during the pandemic. Students find creative ways to both learn and practice while masked and distanced from community members. A positive outcome of being online is the ability to invite environmental activists and...

On Privilege as Choice
Hita Unnikrishnan, Sheffield

Two incidents stand out particularly from my memories as a young child. In the first one, I was perhaps 5 or 6 years old—at that age when we ran out of the housing colony and into the streets to play a game of hopscotch or whatever else took our fancy....

What is One Tree Worth?
Carly Ziter, Montreal

Writing this during National Forest Week here in Canada, I’m reflecting (as I frequently do) on the urban forest. As a scientist, I often find myself collapsing the beautiful, multidimensional, urban forest into a few general measurements: stand density, canopy cover, biomass, etc. But as an urban resident, I cherish...

The Hills Save Us
Diana Wiesner, Bogota

En español. Citizenship is derived from city, and floristry from forest or jungle. Forest and human being live a socio-ecological pact in which the forest becomes a new citizen respected in its integrity, stability, and extraordinary beauty. Both benefits, as the utilitarian logic of exploitation is abandoned and the logic...

Ecosystems as a Framework for Urban Planning: Reconnecting. Rediscovering. Reinvigorating.
Jennifer Dowdell, Baltimore

If we peel back the layers of our urban infrastructure and examine the ecological patterns that originally formed the landscapes beneath our feet, we can shape more resilient cities through an interdisciplinary and inclusive urban design process based on the braided narratives of place: ecology, history, and culture. More than...

Why Would the Economy Need Biodiversity?
Nadezhda Kiyatkina, Moscow

And What Grassplots, Amur Leopard, and Mold Have in CommonWhat is biodiversity for? Some don’t need that question answered: you just adopt a philosopher’s perspective, and everything becomes clear—all living things have the right to dwell on the planet. For others, the question is confusing. Those trying to find a quantitative answer to...

The Challenges for Innovating in Green and Blue Infrastructure: The Case of an Innovative Drainage Approach in Belo Horizonte, Brazil
Jose Puppim, São Paulo Carlos Rigolo, São Paulo Leon Rangel, São Paulo

Green and blue infrastructure (GBI), a form of nature-based solutions (NBS), can provide huge benefits for cities, as GBIs are innovative ways to connect biodiversity and people. Besides the direct functions that the infrastructure provides (e.g. flood prevention or cooling effect), there is also a series of co-benefits that nature...
