Cities are melting pots.  I expect we understand this metaphor best as it relates to human beings. Cities around the world grow because people keep moving into them.  People move from nearby rural areas, from other regions in the same country, or from around the world.  When they arrive, they...

In recent presentations about green cities and green urbanism I often play for audiences several common natural sounds, to see whether they recognize what they are hearing.  Here is one of the sounds I often play—something commonly heard in communities in the eastern US. Click here for a mystery nature...

My second contribution to the Nature of Cities blog was scheduled to fall around that awkward moment at the start of the New Year when productivity is at its lowest ebb. Instead of sitting down to the task at my own snow-bound desk in upstate New York, I find myself...

One hundred ninety two national governments and the EU have signed the Convention on Biological Diversity (CBD), pledging to work towards its three objectives (see here).  In reality, much of the onus falls on local governments although, often, neither level is aware of this nor how it should take place....

Like an ancient prophet, armed with forebodings of doom and destruction, Hurricane Sandy bore down on New York City in the early hours of 30 October, 2012.  An extra-tropical cyclone, a thousand miles wide and armed with hurricane strength winds, Sandy was only eight days old.  A fitful infant terrible,...

Cities are ecological spaces.  But only relatively recently has this new vision of ecologically sophisticated cities gained momentum.  Today, in increasing numbers, scientists, designers, and practitioners create useful knowledge about the nature of cities through study and research that can inspire public debate and decision makers.  Thinkers imagine how to...

Environmental traumas are here.  Global climate is a reality that is bringing extremes in weather as we have seen recently with the devastating impacts of Hurricane Sandy in the northeast of the USA.  And in the last several years there have been massive earthquakes that have devastated cities in Japan,...

In his book Green Urbanism Tim Beatley touted Portland, Oregon as one example of progressive regional, bioregional, and metropolitan-scale greenspace planning in the U.S.  It is true that the Portland metropolitan region is well known for its land use planning and sustainable practices.  Portland itself has more LEED buildings than any...

It is interesting that we think of nature in cities only as fauna and flora.  Mineral nature—the rocks and inert resources—is the stage on which living nature is set.  In cities, this means that the embedded nature all around us, that has been extracted from the Earth like the processed...

In 2008 the London Natural History Society celebrated its 150th anniversary with a conference on ‘London’s Natural History: past, present and future’. I was asked to consider future prospects. What changes might we expect in London’s natural history in fifty year’s time, and what are the prospects for the Society?...

I left Springfield to study architecture in 1974, two years after passage of the Clean Water Act of 1972. The first watershed association in the U.S. was established the Connecticut River Watershed Council two years before my birth in 1956. I can measure my return to the Connecticut River Valley...

I have always thought – I am really lucky because I live in a city with rich biodiversity that still remains in patches spread in the hills and close to the ocean. In spite of other problems we have, being close to nature is a great asset that attracts countless...

Who doesn’t love a list? The 100 richest people in the world. The best guitar players of all time. The most beautiful beaches in the world. The world’s “greenest cities”. The USA’s most livable cities. The most resilient cities. For people interested in the particular theme of the list, the lists...

The Convention on Biological Diversity (CBD) currently has 193 Parties. It is indeed a challenge for each of the Parties, as a nation, to implement their commitments to an international convention like the CBD. How can each Party know how successful it has been in fulfilling its obligations to the...

Coming just out of the whirlwind of the eleventh meeting of the Conference of the Parties to the Convention on Biological Diversity, in Hyderabad, India, from 8 to 19 October 2012, there are many reasons to celebrate. The Convention brings together the governments of 192 countries to discuss policies, actions...

It is an irony that despite the magnificent natural beauty of Rio de Janeiro, the city itself is largely devoid of functioning nature. It is now time for Rio to not only to host global events such as the World Cup and Olympics, but to host its primary nature, not...

With the global urban population expected to double to around 6.5 billion by 2050, the future outlook for biodiversity can be positive, particularly if biodiversity is seen as a part of the solution to some of our most urgent development challenges. Biodiversity underpins the functioning of the ecosystems on which...

For the first time in our history, more people live in urban vs. rural areas and humans continue to move into cities. Cities have huge impacts on our natural resources. Urban dwellers consume vast amounts of energy, produce waste, and alter landscapes to the point where native plant and animal...

Botanical gardens (BGs) are places where people like to be. They provide not only amenities and relaxation for the visitors but opportunities to learn about plants and their environment. In many cases they represent one of the few opportunities for city dwellers to connect with nature. At the same time...

The near absence of any discussion of the environment in the presidential debates has led me to think about the state of the U.S. environmental movement. In one sense, conservationists in the U.S. should be proud of all that we have accomplished in cleaning up our air and water, restoring...
