Cities Act as Talks Go On

Bill Clinton and C40 Mayors

Yesterday in downtown Rio, in Forte de Copacabana, there was an entirely different atmosphere than at the Rio+20 negotiations out in Rio’s suburbs. The public — some waiting as long as three hours — filed through the city’s impressive expo on sustainable development. The festive and hopeful mood of school-children and local ‘Cairiocas’ seemed to buoy the mood of the mayors and officials in the main auditorium.

Some 2000 guests looked on as mayors and their friends like Bill Clinton (via video conference), national government, business and World Bank representatives launched a new initiative to reduce methane emissions though solid waste management. The C40 Solid Waste Network in partnership with the World Bank will focus on providing cities with technical assistance to develop projects that reduce methane gas production.

Supporting People-Smart Regions

During this time, I also attended the UrbanTec Conference in Beijing and was struck by how various presentations on ‘smart cities’ emphasized that ICT systems were the key to building more resource efficient and resilient cities.

Invictus: Elinor Ostrom’s Gift

Elinor OstromAfter months of expectation and years of very hard (and in some cases, not hard enough) work towards the goal of sustainable development, heads of state and environmentalists alike are gathering at Rio+20 to determine what we’ve accomplished in the last two decades and how we’re going to pave the road that lies ahead.

Up until the day before departing for Rio, I approached this conference with a sense of foreboding. Like many, I thought Rio+20 would lead to disappointment and heart-break for environmentalists; on the one hand because we’d find out we’re farther behind than we expect on our road towards sustainable development, and on the other, because we’d realize that our representatives are unwilling to compromise to the degree that our planet needs to survive. Then, on June 12th, I changed my mind.

What a Waste: Time to Pick It Up

What a Waste publication coverAsk any city manager or mayor what their top priority is and you’re likely to get ‘solid waste’ as an answer. You would think in today’s age we would have solved the waste management challenge and moved on to the next slightly more glamorous municipal service. Not so; and more than ever cities now need to pick it up a notch on solid waste management.

Solid waste is still probably the world’s most pressing environmental challenge. In poorer countries, solid waste can use up to more than half of a city’s overall budget; around the world there are more solid waste workers than soldiers; and despite the more than $225 billion spent every year on solid waste, in many low income countries less than half the waste is collected in cities.

The 7 Habits of Highly Effective Cities

  1. Number SevenBe Proactive. There’s much any city can do today. Even without sufficient budget or authorization from ‘senior levels’ of government, every city has a full menu of things that can be carried out immediately, generating positive momentum and goodwill. Business rewards the active entrepreneur, and the public desperately wants active cities. The rewards are great.
     
  2. Plan – Plan Right. All cities carry out master plans for their key services, long-term infrastructure needs, and land use planning. Before starting these plans, the end needs to be clear. They are guidance documents, aspirational, and ways to rally supporters and give fair hearing to opponents. But a plan, no matter how good, can never be seen as a finished product. Before starting the plan an agreement is needed that the city is moving forward on this issue: the plan is the vehicle to bring along as many supporters as possible and identify potential potholes and trouble en route. Like a city, good plans are living documents. 

Providing Clean Drinking Water for Cities in Turkey

Across the world, countries facing rapid, and often unplanned, urbanization deal with a number of challenges that affect their growing populations. The issues range from a lack of access to decent housing and basic services such as sanitation, water, healthcare, electricity and transport. This has adverse impacts on the quality of urban living. It also undermines the efforts of cities to achieve their full economic potential.

Building Resilience for the Urban Poor - Let’s Get Moving

In the many slums I have visited in Latin America, Asia and Africa, I am always struck by the resourcefulness and resilience of residents. Slum dwellers face many hardships in their daily life – low incomes, overcrowded living conditions in high risk areas such as flood zones or steep hillsides, and limited access to clean water, sanitation, transport or solid waste services.

These challenges are only made worse by the impacts of climate change and natural hazards. Heavy rains can quickly turn into a disastrous flood as a result of insufficient or ineffective drainage.  Such flooding can destroy the limited assets of poor households, halt economic activity, contaminate water supply, lead to disease and displace residents.   With the increase in weather extremes, it is anticipated that such events will happen with recurring frequency.

Detroit: A Biography

Dan Hoornweg's picture

Detroit: A Biography by Scott Martelle provides a unique glimpse into the life and history of one of America’s used-to-be, and maybe-again, great cities. From the outset you can tell that Mr. Martelle is more than an observant journalist; he’s a native. He’s got skin in the game.

Providing a biography of Detroit is a clever way to help the reader understand the nuances of what brought the city to where it is today. But the book reads more as an obituary than a city-in-progress biography. The closing Epilogue claims, “There is no real answer to the troubles afflicting places like Detroit”.

Innovative Approaches Urgently Needed to Deliver Energy to Urban Poor

Back in 2004, the electrical utility in Brazil’s biggest city had a major problem. AES Eletropaulo was losing a large proportion of its revenue due to almost half-a-million illegal connections, most of them in São Paolo’s slums. Not only that, but they were causing often multiple-house fires on a monthly basis, along with frequent electrocutions.  But the utility’s efforts to fix the problem were stymied by its poor relations with slum-dwellers, which made it almost impossible to work in these communities.

Guns Don’t Kill People: Nor do Cities Generate 70% of the World’s GHG Emissions

Sooner or later, anyone living in the US will hear a gun rights advocate say that ‘guns don’t kill people, people do.’ Semantics, but true. While we’re on semantics, strictly speaking, cities are not responsible for GHG emissions. Rather the people, or more specifically, those earning the most money, almost all of whom live in cities, are responsible for the vast majority of the world’s GHG emissions. But that is not nearly as easy to communicate, and messaging is important.

car exhaustOn cities and GHG emissions, what is the message we really need to communicate? First, it’s true, if you add up all the GHG emissions – direct (e.g., out the back end of our car) and indirect (e.g., the trees cut down for pasture or the belches from the cattle used in our hamburgers) – residents of cities are responsible for more than 70% of the world’s GHG emissions (and likely more than 80%). This should not be much of a surprise, as these same people are responsible for more than 80% of the world’s economy. GHG emissions are a by-product of the stuff we buy and do.
