Lead Urban Specialist Victor Vergara tells us all there is to know about the program and what's next for MetroLab.
In this video, Lead Urban Specialist Maria Angelica Sotomayor presents some of the key findings from the diagnostic, and explains how the World Bank is collaborating with local stakeholders to make Addis Ababa a stronger, more resilient city.
With most of the global population and capital goods now concentrated in urban areas, cities are key to social development and economic prosperity. Urbanization, globalization, and climate change are interacting in a way that is unprecedented, and urban service delivery systems are becoming increasingly interlinked.
Join us for a live online session this Saturday, Oct. 10 at 11:30 a.m. ET (15:30 GMT) straight from the Bank-IMF Annual Meetings 2015 in Lima, Peru. A discussion with senior leaders and government officials about how to support cities in becoming more socially, environmentally, and fiscally sustainable.
The event will be livestreamed in five languages and live tweeted and live blogged. We’ll have English and Spanish-speaking urban specialists joining our live blog to address your comments and answer your questions as the session progresses –and the panel in Lima will take a few questions from our online audience.
To see the list of panelists and other details, and to watch and join the live discussion, please go here (also in Français, español, Português and العربية )

Cities are a puzzle for some and inspiration for others. As engines of economic growth, they are also hubs of rapid urbanization, a rising middle class, and a growing population. These three mega-trends drive global environmental degradation yet are only part of the important challenge facing cities today.
While consuming over two-thirds of global energy supply and emitting 70% of all carbon dioxide, cities are also uniquely vulnerable to climate change. Fourteen of the world’s 19 largest cities are located in port areas. With sea level rise and increased storm activity, these areas are likely to face coastal flooding, damage to infrastructure, and compromised water and food security. Under these conditions, meeting urban population’s growing production and consumption needs for food, energy, water, and infrastructure will overload rural and urban ecosystems.
To tackle these issues, the Global Environment Facility (GEF), in collaboration with the World Bank Group (WBG), launched the Sustainable Cities Program to engage 23 cities in 11 developing countries. Hailing from one of such countries, two urban development specialists working on each side of the Program explain why making cities more sustainable appeals to them.

You cannot imagine my surprise while reading a BusinessWeek article last July about an innovative way to transform India’s litter into partial substitute for bitumen in asphalt to build roads!
Well, this transformative method arguably holds larger potential than the “garbage to music” recycling approach I recently wrote about in my first post about creative ways to manage waste. “Garbage to roads” was pioneered by an Indian chemist called Vasudevan, and it could help not only in getting rid of tons of plastic litter- thick acrylics and bottles, grocery bags and wrappers-- but in building roads at the same time. It’s a win-win solution for all.
Urbanization is the most powerful force shaping the planet today. This can be good news as urbanization is the best bet we have to meet our global poverty reduction targets. Cities generate our wealth, our culture, and our innovation. This is also bad news since cities generate the lion’s share of the world’s GHG emissions, and cities are responsible for most of the planet’s current decline in biodiversity. Cities also generate solid waste; lots of it and the amount is growing fast.
‘Peak waste’ – that point in time when all the waste from all the cities finally plateaus around the world, and then slowly starts to decline, is not on track to happen this century. Estimates are that it will peak at three-times today’s current waste generation rate. Peak waste is an excellent proxy for humanity’s cumulative global environmental impact; therefore we are on track to triple today’s overall global environmental impact. Our ‘assault on the planet’ will start to subside on the other side of peak waste. Therefore we must move peak waste forward and reduce its intensity when it finally does arrive.
For years, the thermal energy beneath the surface of the Earth has been used for many things. Bathing, agriculture, aquaculture, industrial or heating purposes, or even to generate power; the results are often impressive. The Earth’s structure radiates a constant flow of thermal energy outwards to the crust. This phenomenon is a natural, renewable source of heat which provides a substantial contribution to the mitigation of greenhouse gas emissions.
Reduce, Reuse, Recycle… Recover. As the population in large cities worldwide grows, waste management becomes an even bigger challenge. Recycling programs can divert large amounts of materials from landfills but some garbage still needs to be disposed of in landfills or Energy From Waste (EFW) sites. EFW facilities are capable of recovering energy from garbage that would otherwise be unused in landfills.
EFW and landfill gas capture systems operate on similar principles: produce steam to turn a turbine which generates electricity. The difference is the fuel used to produce the steam. Landfill gas based electricity generation relies on methane from the decomposition of organic material, while EFW facilities combust the solid waste. Both are good options as they prevent methane gas from escaping into the atmosphere. Methane has a global warming potential 72 times that of carbon dioxide. Both options sound good, so which is better? The better question is: ‘How much land and money do you have’?
While green buildings, by their most obvious definition, address environmental impacts, they also have wide implications for human health, safety and productivity. Well-ventilated green schools can reduce instances of asthma in students. Green offices with day lit spaces boost employee productivity and attendance. Patients heal faster in green hospitals with views to nature.
