More than 50% of the world’s population live in cities; making cities sustainable is therefore an imperative in building a sustainable society. Cities are complex in terms of both infrastructure and the range of social interactions that makes the city operate. It is possible to make cities work like living organisms; capturing renewal energy, fully recycling waste and providing a vibrant, clean and enjoyable place to live. They can also appear like cancerous growth growing into mega metropolises from which the natural world is excluded.
I have just spent a very pleasant weekend in Bristol at the Bristol Harbour Festival, a celebration of culture and leisure. Throughout the city there were outdoor events ranging from concerts and circus performances to street buskers and market stalls. The theme was fun, enjoyment and entertainment; the sun shone and everybody seemed to have a good time. The hustle and bustle of people in close proximity brings joy and fulfilment but if resources are insufficient this can switch to conflict and strive. It is vital that we make our cities sustainable to reap the pleasures of communal living on show at the festival.
The City Council’s intention is to become a green city was evidenced by numerous recycling containers and policemen on bicycles. Bristol came top of the Forum for the Future’s index of UK Sustainable Cities in 2008 but has since slipped to 4th behind Newcastle, Leicester and Brighton. This competition between city leaders, to be the greenest city, should engage a virtuous cycle as each city tries hard to outdo the other.
Green aspirations are not the same as delivering green solutions. Our hotel was a prime example of how to use excess energy to little good effect; we slept very badly until we opened the window, turned off the air conditioning and let the night air waft through the room. The recycling in evidence was collecting and sorting piles of trash with little evidence of true recycling. Bristol is doing well on the relative scale presented in the Sustainable Cities Index but if there was an absolute scale from 1 to 10 ― with 1 being unsustainable and 10 being fully sustainable― Bristol would score a 1.1.
To make our cities free from fossil-fuel dependency and resources delivered through long supply chains will be a tough challenge. Bristol should be praised for taking the first step but it must be seen as a small first step on a long journey.
Note:
The Sustainable Cities Index tracks progress on sustainability in Britain’s 20 largest cities, ranking them across three broad baskets: environmental performance; quality of life; and future-proofing – how well they are addressing issues such as climate change, recycling and biodiversity.
