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?
There is a unique space where you can encounter everyone from developers of self-driving cars in Silicon Valley to city planners in Niamey to humanitarian workers in Kathmandu Valley: the global OpenStreetMap (OSM) community. It comprises a geographically and experientially diverse network of people who contribute to OSM, a free and editable map of the world that is often called the “Wikipedia of maps.”
What is perhaps most special about this community is its level playing field. Anyone passionate about collaborative mapping can have a voice from anywhere in the world. In the past few years, there has been a meteoric rise of locally organized mapping communities in developing countries working to improve the map in service of sustainable development activities.
The next opportunity to see the OSM community in action will be the November 14th mapathon hosted by the Global Facility for Disaster Reduction and Recovery (GFDRR)’s Open Data for Resilience Initiative (OpenDRI). Mapathons bring together volunteers to improve the maps of some of the world’s most vulnerable areas, not only easing the way for emergency responders when disaster strikes, but also helping cities and communities plan and build more resiliently for the future.
They play such a pivotal role in addressing global challenges and improving citizen’s lives that
Yet, it is nations that have led the discussions around solutions for a rapidly urbanizing world, leaving the voices of cities to a secondary role.
To highlight and share effective solutions to some of the most pressing challenges of our time, over 30 mayors from around the world will gather at the First Urban 20 Mayors Summit in Buenos Aires, Argentina, October 29-30, 2018. Together, they will provide concrete, experience-based recommendations to the leaders of the G20 countries on what it takes to achieve urban sustainability, inclusion, and prosperity.
As a strategic partner of the summit and the overall Urban 20 (U20) Initiative, the World Bank Group – including the World Bank and the International Finance Corporation (IFC) – is committed to helping global cities bring their expertise, needs, and voices to the center of global discussions on sustainable development. At the summit, the World Bank will present a series of knowledge notes to inform the U20 discussions and promote the exchange of ideas and innovative approaches to complex development issues, including:
- The future of work in cities
- Affordable housing in the world’s cities
- Urban mobility, health and public spaces
- Urban water resilience
In this video, World Bank Senior Director Ede Ijjasz-Vasquez (@Ede_WBG) and Lead Urban Specialist Horacio Terraza (@TerrazaH) talk about the importance of the U20 Initiative, the World Bank’s participation in the First U20 Mayors Summit, and what is next for U20 cities after the summit in Buenos Aires.

Post-disaster assessments changed my life by starting my career in disaster risk management. Three months after arriving in Indonesia as the World Bank’s environment coordinator, the Indian Ocean tsunami and related earthquakes struck Aceh and Nias at the end of 2004. I was asked to pull together the economic evaluation of the disaster’s environmental impact as part of what was then known as a damage-and-loss assessment. Subsequently, the World Bank, United Nations and European Union agreed on a joint approach to crisis response in 2008, including a common methodology for post-disaster needs assessment (PDNA).
Now that we have a decade of experience with this approach, what have we learned and how can we do a better job in the future?
Small, landlocked, and resource-rich Lao PDR has been quietly maintaining its place as one of East Asia and Pacific’s fastest growing economies for nearly 20 years. Since 2000, the average economic growth rate of the country has been nearly 8 percent. This growth has propelled Lao PDR through many positive milestones, including meeting the criteria of Least Developed Country graduation for the first time this year. Meanwhile, poverty declined from 34 percent in 2003, to 23 percent according to most recent data, and incomes for many have risen.
Droughts, floods, hurricanes, and other disasters displaced over 24 million people in 2016. This is crucial, as land and homes are usually the main assets that people have.
Land and geospatial information tells the what, who, where, how much, and other key attributes of a property. Without this information, it is almost impossible for cities and communities to develop proper disaster response or preparedness plans.
– by providing accessible and instant data on disaster impact, the value of losses, the beneficiaries, as well as the levels of appropriate compensation and required investment to restore activities.
The World Development Indicators (WDI) is the World Bank’s premier compilation of international statistics on global development. Drawing from officially recognized sources and including national, regional, and global estimates, the WDI provides access to almost 1,600 indicators for 217 economies, with some time series extending back more than 50 years. The database helps users—analysts, policymakers, academics, and all those curious about the state of the world—to find information related to all aspects of development, both current and historical.
An annual World Development Indicators report was available in print or PDF format until last year. This year, we introduce the World Development Indicators website: a new discovery tool and storytelling platform for our data which takes users behind the scenes with information about data coverage, curation, and methodologies. The goal is to provide a useful, easily accessible guide to the database and make it easy for users to discover what type of indicators are available, how they’re collected, and how they can be visualized to analyze development trends.
So, what can you do on the new World Development Indicators website?
1. Explore available indicators by theme
The indicators in the WDI are organized according to six thematic areas: Poverty and Inequality, People, Environment, Economy, States and Markets, and Global Links. Each thematic page provides an overview of the type of data available, a list of featured indicators, and information about widely used methodologies and current data challenges.

Last week we had World Food Day on October 16 and World Poverty Day on October 17. The good news from World Poverty Day is that there is global progress on reducing extreme poverty. Based on the latest available data, it is estimated that in 2015 there were 736 million people living on less than US$1.90/day, which compares very favorably to the 1,895 million people living in extreme poverty in 1990. And while the world’s population grew from 5.3 billion in 1990 to 7.4 billion in 2015, the poverty rate fell from 36 percent to 10 percent or 1 percentage point per year on average over this period.
For many countries, however, the impact of disasters can be much more devastating. An effective strategy to managing climate and disaster shocks calls for resilience, risk financing instruments and institutional capacity that empowers early response and gives teeth to recovery and reconstruction plans.
