What is a common thread between Argentina, Maldives, and Zambia? In each of these countries, the World Bank provided guarantees to support transparent auctions for renewable energy. Through these, I have seen how the Bank’s involvement helped increase private investors’ confidence, attract world-class developers, and ultimately reduce tariffs.

Drawing on 10 years of diverse experience in the power sector in both public and private organizations, my role is to help bridge the divide between public and private parties and help each side better understand the other. The World Bank is ideally positioned for this. Both sides understand the World Bank carries out a detailed due diligence and ensures the auction meets international standards. Both sides appreciate the World Bank will be an honest broker if issues arise. Because of its long term and continuous involvement in our client countries, the World Bank can help identify and solve issues early on. As such, no World Bank project-based guarantee has ever been called.

The secret sauce for making the New Urban Agenda a success

Modernity’s most common story spanning national, cultural and religious borders is about people moving from rural areas to the cities. By 2030, 80% of the world’s population will be living in urban areas, following the dream of better jobs, education, and health care.

Too often, however, that dream risks remaining an urban daydream, due to natural disasters such as hurricanes, earthquakes, and floods, as well as climate change. Those of us working to help these families find a better future must focus more on ways to support efforts to protect their lives – and their livelihoods.
 
In the 40 years since the launch of Habitat I, governments and municipalities throughout emerging and developing countries have been proving that their cities can be not only inclusive and secure, but also resilient and sustainable. However, unless they increase their speed and scale, they are unlikely to achieve the goals of the “New Urban Agenda” and its Regional Plans, launched at Habitat III in 2016.
 
From our perspective helping governments in Latin America and the Caribbean, and ahead of the World Urban Forum taking place in Kuala Lumpur, Malaysia in February, let us share three key ingredients necessary to achieve that goal:

How to manage urban expansion in mega-metropolitan areas?

As the world becomes increasingly urbanized, the number of megacities is growing rapidly.

Today there are 37 cities worldwide with populations of greater than 10 million, and 84 with populations greater than five million. More than three quarters of these cities are in developing countries. Together with their surrounding metropolitan areas, these cities produce a sizable portion of the world’s wealth and attract a large share of global talent.

These megacities face a series of common challenges associated with managing urban expansion, density, and livability—in a manner that takes advantage of the benefits of productive agglomerations, while mitigating the disadvantages of such high degrees of congestion and urban density.

Moreover, like other metropolitan areas, megacities face challenges of effectively coordinated planning, infrastructure development, and service delivery across multiple jurisdictions. Indeed, the New Urban Agenda issued at the Habitat III conference in 2016 identified metropolitan planning and management as one of the most critical needs to ensure sustainable urbanization.

Argentina set ambitious targets of providing universal access to water and 75 percent access to sewerage services for its citizens. How can the country move toward this goal? 
 
That was the theme of the discussion on “Argentina Day” at the recent International Water Association (IWA) Water and Development Congress and Exhibition held in Buenos Aires, where water professionals from around the world and Argentinian officials met to exchange knowledge, experiences, and strategies.

Promoting nationally aligned climate action in Latin American cities

Urban populations are booming, and the choices that local governments make today about managing their greenhouse gas (GHG) emissions directly impact the long-term health and economic well-being of their cities. Climate action at the local level is critical; however, most cities in low and middle-income countries have yet to integrate low carbon strategies into their planning process.

How teaching with the test (not to the test) improves learning

Rafael de Hoyos's picture

“Test and punish”?

There’s a debate raging in American schools today: how (and how much) should children be tested?

The No Child Left Behind (NCLB) Act created a system where all children in all schools from grades 3 to 8 must be tested each year. Critics refer to this accountability architecture as “test and punish,” with stakes such as school funding (or closings!), bonuses for teachers, or grade promotion for students all riding on performance. There is evidence that NCLB improved learning outcomes, but improvements came at a high cost: In addition to teaching to the test, this approach can lead to a number of perverse incentives, like keeping weaker students at home on test day, narrowing the curriculum, or downright cheating. Worse, some have said they can serve to mask and contribute to the structural race and class inequalities in the United States.

What can satellite imagery tell us about secondary cities? (Part 2/2)

Sarah Elizabeth Antos's picture
In the previous blog, we discussed how remote sensing techniques could be used to map and inform policymaking in secondary cities, with a practical application in 10 Central American cities. In this post, we dive deeper into the caveats and considerations when replicating these data and methods in their cities.

Can we rely only on satellite? How accurate are these results?

It is standard practice in classification studies (particularly academic ones) to assess accuracy from behind a computer. Analysts traditionally pick a random selection of points and visually inspect the classified output with the raw imagery. However, these maps are meant to be left in the hands of local governments, and not published in academic journals.

So, it’s important to learn how well the resulting maps reflect the reality on the ground.

Having used the algorithm to classify land cover in 10 secondary cities in Central America, we were determined to learn if the buildings identified by the algorithm were in fact ‘industrial’ or ‘residential’. So the team packed their bags for San Isidro, Costa Rica and Santa Ana, El Salvador.

Upon arrival, each city was divided up into 100x100 meter blocks. Focusing primarily on the built-up environment, roughly 50 of those blocks were picked for validation. The image below shows the city of San Isidro with a 2km buffer circling around its central business district. The black boxes represent the validation sites the team visited.

What can satellite imagery tell us about secondary cities? (Part 1/2)

The buzz around satellite imagery over the past few years has grown increasingly loud. Google Earth, drones, and microsatellites have grabbed headlines and slashed price tags. Urban planners are increasingly turning to remotely sensed data to better understand their city.

But just because we now have access to a wealth of high resolution images of a city does not mean we suddenly have insight into how that city functions.

The question remains: How can we efficiently transform big data into valuable products that help urban planners?

In an effort a few years ago to map slums, the World Bank adopted an algorithm to create land cover classification layers in large African cities using very high resolution imagery (50cm). Building on the results and lessons learned, the team saw an opportunity in applying these methods to secondary cities in Latin America & the Caribbean (LAC), where data availability challenges were deep and urbanization pressures large. Several Latin American countries including Argentina, Bolivia, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama were faced with questions about the internal structure of secondary cities and had no data on hand to answer such questions.

A limited budget and a tight timeline pushed the team to assess the possibility of using lower resolution images compared to those that had been used for large African cities. Hence, the team embarked in the project to better understand the spatial layout of secondary cities by purchasing 1.5 meter SPOT6/7 imagery and using a semi-automated classification approach to determine what types of land cover could be successfully detected.

Originally developed by Graesser et al 2012 this approach trains (open source) algorithm to leverage both the spectral and texture elements of an image to identify such things as industrial parks, tightly packed small rooftops, vegetation, bare soil etc.

What do the maps look like? The figure below shows the results of a classification in Chinandega, Nicaragua. On the left hand side is the raw imagery and the resulting land cover map (i.e. classified layer) on the right. The land highlighted by purple shows the commercial and industrial buildings, while neighborhoods composed of smaller, possibly lower quality houses are shown in red, and neighborhoods with slightly larger more organized houses have been colored yellow. Lastly, vegetation is shown as green; bare soil, beige; and roads, gray.

These winning photos capture the future of sustainable cities

Xueman Wang's picture
The premise behind the Sustainable Cities photo competition was simple. We wanted to learn what people around the world “see” when they hear the words “sustainable cities.”
 
The submissions – and we at the Global Platform for Sustainable Cities received more than 90 entries from over 40 countries around the world – are very revealing.

What the photographers tried to communicate was a need: both the urgent need for infrastructure that leads to more resilient, sustainable cities, or a need to aspire to greener ideals of building sustainable communities for all.

There is no better day than today, World Cities Day, for us to share with you the 10 finalists – including 3 winners and an honorable mention for climate action – of the photo competition.

In the winning photo by Yanick Folly, one can practically feel the chaos of a city in Benin, the smell of exhaust fumes as cars crawl up alongside motorcycles and pedestrians down narrow alleyways.

Yanick Folly (Benin) – Winner
Growing day by day, our world is always moving. Just see the big vibrant Benin market. #SustainableCities

The photo is also a reminder that cities are made of people. Any set of solutions for “sustainable cities” will have to make sense to a city’s inhabitants, who tread its streets daily.
 
In other photos, the aspiration is palpable. 

Many of the photographers are nationals of developing countries from all over the world. Yet quite a few of them shared photos of cities we regard as environmentally friendly: Singapore, Amsterdam, London, and Paris... We saw many photos of parks in developed countries, and heard the same message: These green spaces and pedestrian walkways are what we want in a city.

Many photos also reflect the vast difference between the aspirational city, and what most people actually live with.
 
We received photos of what many of us may categorize as rural areas, but we should reconsider these preconceptions: some “cities” in developing countries are little more than makeshift towns.
 
So, it is all the more reason why we are excited about this winning photo by Oyewolo Eyitayo from Nigeria. You might think this is an uneventful photograph of a typical urban suburb. Except that the half dirt roads are lined with solar panels.

A portrait of PPPs in Latin America

As in many regions, countries in Latin America and the Caribbean are underinvesting in infrastructure—spending in the sector is only about half of the $300 billion needed annually to encourage growth and reduce poverty. Addressing this issue involves the successful interaction between public officials and leading infrastructure actors, particularly in the private sector. Stimulating such public-private dialogue is a priority for the Inter-American Development Bank (IDB) Group, a technical partner of the Global Infrastructure Facility (GIF). Along with other partners, our recently established PPP unit supports governments, international financial institutions, and the private sector to develop infrastructure projects.
 
It was therefore a privilege for me to moderate a panel on country infrastructure programs in Latin America at the GIF’s annual Advisory Council meeting in April 2017. We covered three countries—Colombia, Argentina and Peru—at different stages of PPP market development. The findings were encouraging and illustrate a path forward for other countries in the region:
