Machine learning algorithms are excellent at answering “yes” or “no” questions. For example, they can scan huge datasets and correctly tell us: Does this credit card transaction look fraudulent? Is there a cat in this photo?
But it’s not only the simple questions – they can also tackle nuanced and complex questions.
Today, machine learning algorithms can detect over 100 types of cancerous tumors more reliably than a trained human eye. Given this impressive accuracy, we started to wonder: what could machine learning tell us about where people live? In cities that are expanding at breathtaking rates and are at risk from natural disasters, could it warn us that a family’s wall might collapse during an earthquake or rooftop blow away during a hurricane?
Within a century, Japan would become the world’s second largest economy. Its growth has been fueled by cities such as Tokyo, Yokohama, Osaka, and Kobe. Japanese cities can offer a myriad of lessons to their counterparts in developing countries.
Japanese cities are also at the forefront of dealing with some of the world’s most pressing challenges. For example, cities like Osaka and Toyama have developed a number of tools to address the social issues caused by rapid aging. Most developed and developing cities in the world will face similar challenges in the years to come. Providing a platform where these cities can learn from the experience of Japanese cities may lead to significant development impact.
Supported by a partnership between the World Bank and Japan, the Tokyo Development Learning Center (TDLC) does just that.

Globally, up to 1.4 million people are moving into urban areas per week, and estimates show that nearly 1 billion new dwelling units will be built by 2050 to support this growing population.
Cities are where most people live and most economic activity takes place.
When people cannot find a decent and safe place to live, or are discriminated against because of their race, religion or where they live, or lack the skills, education and transportation needed to find a job to support themselves, something needs to change.
To make cities safer, more inclusive, and more resilient to a range of shocks and stresses, mayors, planners, and other city leaders should support integrated approaches promoting social, economic, and spatial inclusion. City leaders need to carry out this work in close partnership with the communities themselves.
From April 23–27, 2018, representatives from 16 cities in 13 countries visited Japan for a Technical Deep Dive on Safe, Inclusive, and Resilient Cities to learn from one another about improving urban safety, inclusion and resilience. In this video, Jefferson Koije (Mayor of Monrovia, Liberia), Ellen Hamilton (World Bank Lead Urban Specialist), and Phil Karp (World Bank Lead Knowledge Management Officer) discuss how cities can address these crucial aspects of urban resilience.

Imagine you were working in development and poverty reduction in the early 1990s (I was!). Only one website existed in all the world in August 1991 (today there are over 1.5 billion). Mobile phones were expensive, rare, and clunky. Very few would anticipate a situation in which India would have more mobile phones than toilets.
To paraphrase Bill Gates: we tend to overestimate the changes that will happen in the short term and underestimate those in the long term.
Cities need jobs and opportunities for their citizens and the means to generate tax revenues to fund projects that meet their populations’ growing demand for basic services. The WBG flagship report on Competitive Cities outlines how
In November, 2017, we spent a week with approximately 30 city and national government officials and policymakers from several countries, including Argentina, Chile, Croatia, Egypt, Ethiopia, Malaysia, Philippines, Romania, South Africa, Tunisia and Uganda. These leaders represented diverse cities across the world, all with a common objective – how to make their cities and regions more competitive?
Many were dealing with a fragmented institutional landscape, often with overlapping jurisdictions – necessitating clarity of institutional circuits and processes. Some struggled to coordinate economic development strategies with private sector. Lack of adequate sub-national socio-economic data to drive evidence-based policy making compounded issues.
We spent the week as part of a Technical Deep Dive, studying and living the experience of two exceptional Japanese cities - Yokohama and Kobe. These cities have dealt with:
- population influx,
- industrialized at a rapid pace,
- responded to environmental challenges,
- reached the technological frontier,
- undergone a housing bubble,
- and even went through a major disaster (the Kobe earthquake) and recovered from it.

日本の横浜市と神戸市で行われた本 実務者研修会合では、都市の競争力に関連し、日本の優れた知見を学ぶことができました。横浜市と 神戸市は特に以下について豊富な知見を有しています。
As we approach the 9th World Urban Forum in Kuala Lumpur next week, one of the essential challenges in implementing the New Urban Agenda that governments are struggling with is the provision at scale of high quality affordable housing, a key part of the Sustainable Development Goal (SDG) 11 of building sustainable cities and communities.
When I worked on affordable housing in Latin America, one consistent piece of advice we would give our clients was that it is not a good idea for governments to build and provide housing themselves. Instead, in the words of the famous (and sadly late) World Bank economist Steve Mayo, we should enable housing markets to work. Our clients would always respond by saying, “But what about Singapore?” And we would say the Singapore case is too sui generis and non-replicable.

Now, having lived in the beautiful red-dot city state for two and half years, and
Singapore’s governing philosophy has famously been described as “think ahead, think again and think across.” Nowhere is this more apparent than how the founding fathers designed the national housing program, and how it has adapted and evolved over the years, responding to changed circumstances and needs.
It is hard to believe today but in 1947 the British Housing Committee reported that 72% of a total population of 938,000 of Singapore was living within the 80 square kilometers that made up the central city area. When Singapore attained self-government in 1959, only 9% of Singaporeans resided in public housing. Today, 80% of Singaporeans live a government built apartment. There are about one million Housing and Development Board (HDB) apartments, largely clustered in 23 self-contained new towns that extend around the city’s coastal core.
At the risk of over-simplification, there seem to be four essential ingredients to this astonishing success story:
In just three weeks, early February 2018, representatives of the world’s countries and cities will convene again to discuss “Cities 2030, Cities for All: Implementing the New Urban Agenda” at the world’s premier conference on cities – the Ninth Session of the World Urban Forum (WUF9) in Kuala Lumpur, co-hosted by UN-Habitat and the government of Malaysia.
In the video, World Bank Senior Director Ede Ijjasz-Vasquez (@Ede_WBG) and Director Sameh Wahba (@SamehNWahba) share the World Bank's three priorities at the World Urban Forum.

As the world’s largest financier on urban development, the

Hurricanes Harvey, Irma, and Maria that pounded coastal United States and the Caribbean; the severe drought that struck Somalia; forest fires that are ravaging through southern California… Hard to miss were the natural disasters that displaced – even killed – individuals and families.
There were also the “manmade” disasters – conflicts that erupted or lasted in many parts of the world continued to force men, women, and children out of their homes and homelands.
Yet, turning to the bright side,
Just a couple of weeks ago, for example, global and local leaders gathered at the One Planet Summit in Paris to firm up their commitment – and ramp up action – to maximize climate finance for a low-carbon, disaster-resilient future.
At the World Bank, our teams working on social development, urban development, disaster risk management, and land issues have endeavored with countries and cities worldwide throughout the year to achieve a common goal: building inclusive, resilient, and sustainable cities and communities for all.
How did they do? From our “Sustainable Communities” newsletter,
#1: Africa’s Cities: Opening Doors to the World
Released in February 2017, our report on cities in Africa notes that, to grow economically as they are growing in size, Africa’s cities must open their doors and connect to the world. Improving conditions for people and businesses in African cities is the key to accelerating economic growth, adding jobs, and improving city competitiveness. Two more reports released in 2017 also shined a light on inclusive urban growth in East Asia and the Pacific and in Europe and Central Asia respectively.
