For example, a Cairo-based startup called “Swvl” is disrupting commuting in the In the Middle East and North Africa region by mapping out commuters’ travel directions and enabling app-based, affordable bus rides that can compete with on-demand ride-hailing.
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.
The that has perplexed city planners for years: providing easier access to the mass transit system while ensuring good ridership. Thanks to the GPS tracking device installed on thousands of dockless shared bikes, city planners in China are now equipped with new and better information to analyze the demand for—and the performance of—public transit systems. For the first time, city managers can clearly map out the attractiveness and accessibility of metro stations by analyzing individual-level biking trips.
This innovation is good news to efforts to build more livable, sustainable cities through transit-oriented development (TOD). For example, to support the recently launched GEF Sustainable Cities Integrated Approach Pilot Project, we have been working with Mobike, a major bike-sharing company, to conduct an . Below are a few interesting observations:
- Revisiting the scope of TOD. A commonly accepted textbook definition of the core area of TOD is an 800-meter radius around the metro station or other types of public transit hubs. This definition is based on the distance that can be reached by a 10-minute walk. However, the actual catchment of a metro station can reach a 2-3 km radius when biking prevails, as in Demark and Netherland. Our analysis illustrates that a big chunk of biking trips around metro stations even go beyond the 3km radius (see bright blue traces in Figure 1 below). This indicates that the spatial scope of planning and design around the metro stations should be contextualized. Accordingly, the price premium associated with adjacency to public transit service is more likely to be shared by a broader range of nearby real estate properties than expected.

The data revolution is upon us and the benefits, including improving the efficiency of corporations, spurring entrepreneurship, improving public services, improving coordination, and building profitable partnerships, are becoming more evident.
For public services, the potential gains are impressive. Globally in the electricity sector, an estimated $340 – 580 billion of economic value can be captured by providing more and better data to consumers to improve energy efficiency, and to operators for streamlining project management and the operation of their facilities. Even larger gains ($720 – 920 billion) could be captured in the transport sector.
Exploring the benefits of open data in the solid waste sector has been slower than for other services, however, if you take a closer look, the benefits may be substantial. Solid waste services have a lot to gain – with low service coverage and a lack of modernization in most parts of the world; solid waste services can be costly, representing 10 – 50% of municipal budgets in many developing countries; and it is directly dependent on many actors. To be effective, citizens, institutions, and private companies need to be informed and involved.[Download: What a Waste: A Global Review of Solid Waste Management]
Some examples of what making better quality data available on solid waste services could do include:
The best laid plans… have data. With average waste collection rates of 41% and 68% for low- and lower middle-income countries, respectively, and less than 10% of the corresponding waste disposed in a sanitary manner, many municipalities in the world lack solid waste services. The introduction of modern solid waste systems in these areas represents a monumental organizational change and logistical challenge. It necessitates the introduction of collection services for, among others, each household, and every commercial building and supermarket; the coordination with, informing, and incentivizing all the actors in recycling; the operation of transport services; and the operation of effective disposal or treatment options for the daily, relentless influx of waste. Systematically collecting quality data will help municipalities to undertake strategic planning, integrate service planning into urban planning, and make the necessary decisions that allow them to establish a solid waste system that is properly dimensioned and cost-effective.
The social inclusion of disadvantaged groups is necessary for reducing poverty and boosting shared prosperity, said government representatives, experts, and civil society representatives at a World Bank seminar on Friday, April 21. Persons with disabilities, Indigenous Peoples, as well as lesbian, gay, bisexual, transgender, and intersex (LGBTI) persons form a large part of the world population affected by poverty. They often face multiple discrimination and exclusion because of their overlapping identities, stressed Maitreyi Das, Social Inclusion Global Lead at the World Bank Group.
Patricia Peña, Director General for Economic Development of Global Affairs, Canada, highlighted the commitment of Canada—through its foreign assistance, diplomacy, and domestic efforts—to support policies and programs addressing economic and social inclusion of LGBTI people. Disaggregated data collection is one of the priorities for developing effective responses. Harry Patrinos, Practice Manager at the Bank’s Education Global Practice, made a cross-country assessment of poverty among Indigenous Peoples. Ulrich Zachau, the World Bank’s Country Director for Southeast Asia, discussed the Bank’s ground-breaking data generation efforts on LGBTI persons in Thailand. There is a need to find a shared way of measuring disability, said Nick Dyer, Director General of Policy and Global Programmes at the UK Department for International Development.

My previous blog post surveyed some of the recent trends in developing global measures of urbanization. In this post, I want to turn to a brief discussion for scholars and practitioners on some possible applications and areas of focus for ongoing work:
[Download draft paper "Bright Lights, Big Cities: a Review of Research and Findings on Global Urban Expansion"]
While there are a number of different maps for documenting urban expansion, each has different strengths and weaknesses in application. Coarser resolution maps such as MODIS can be used for mapping the basic contours of artificial built-up areas in regional and comparative scales. On the other hand, high-resolution maps are best suited for individual cities, as algorithms can be used to identify and classify observed colors, textures, shading, and patterns into different types of land uses. These levels of detail are difficult to use for reliable comparisons between cities as the types of building materials, structure shapes, light reflectivity, and other factors can vary widely between countries and regions.
Nonetheless, there are a number of applications for policymakers in this regard, from identifying and mapping green spaces and natural hazard risks to identifying and tracking areas of new growth, such as informal settlements. However, such approaches to land use detection require careful calibration of these automated methods, such as cross referencing with other available maps, or by “ground truthing” with a sample of street-level photos of various types of buildings and land cover as reference inputs for automation. One solution to this is the use of social media and geo-coded data to confirm and monitor changes in urban environments alongside the use of high-resolution satellite imagery.
Nighttime light maps also have gained traction as measures of urban extent and as ways to gauge changes in economic activity in large urban centers. They are probably less useful for documenting smaller settlements, which may be dimmer or have little significant variation in brightness. It is important to correct these types of maps for “overglow” measurement effects—where certain light may “bleed” or obscure the shapes and forms of very large, bright urban areas in relation to adjacent smaller and dimmer settlements (newer VIIRs maps have made some important advances in correcting this).
(land surface coverage comprised of buildings and roads) and population growth across time and space. This impacts how policymakers may understand and prioritize the challenges cities face and what investments or reforms may be needed. In a new paper, “Bright Lights, Big Cities: a Review of Research and Findings on Global Urban Expansion,” I provide a brief introduction to some of the current approaches for measuring urban expansion and review the comparative findings of some recent studies.
The UN’s World Urbanization Prospects (WUP), perhaps the most comprehensive and widely cited measure of urbanization across the world, draws from a compilation of country-level population totals based on administrative definitions. A key weakness with this set is that since each country defines “urban” differently, it is difficult to accurately compare one country’s urbanization to another, as well as to estimate the urban population of a group of countries or the world itself. Recent work has provided more sophisticated ways to measure urban growth and expansion using both satellite map data and careful application of population data.
We may not know exactly what the world will look like in two decades, but we know this: it is going to be a world of cities.
Each year, urban areas are growing by an average of more than 75 million people – more than the population of the world’s 85 smallest countries combined.
For the world’s economy, this is great news, since cities produce 80 percent of global GDP, despite currently being home to only 55 percent of the population. But it is a problem for urban infrastructure, which can’t keep up with such fast-paced growth. As a result, – from flooding and landslides that can decimate informal housing settlements, to earthquakes that can devastate power grids and water systems.
These risks could be disastrous for the urban poor, 881 million of whom currently live in slums (up 28 percent since 2000). And climate change – which is increasing the intensity and frequency of natural disasters – will only exacerbate the problem. For this reason, multilateral and government institutions now see resilience and climate adaptation as integral pillars of development.
The Swiss State Secretariat for Economic Affairs (SECO), for example, considers low-emission and climate-resilient economies to be key to global competitiveness. A recent report by the World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR) found that climate change may force up to 77 million urban residents into poverty by 2030 – unless we take action to improve the resilience of cities around the world.
Nowadays, we don’t think twice before ordering an Uber or using Open 311 to report an issue to our municipality. In the developing world, the impact has been even greater. For example, in Latin America and the Caribbean, cellphone coverage increased from about 12 subscriptions per 100 people in 2000 to over 114 in 2014, and
The city of La Paz in Bolivia is piloting a new tool called Barrio Digital—or Digital Neighborhood—to communicate more effectively and efficiently with citizens living in areas that fall within Barrios de Verdad, or PBCV, an urban upgrading program that provides better services and living conditions to people in poor neighborhoods.
The goals of Barrio Digital are to:
- Increase citizen participation for evidence-based decision-making,
- Reduce the cost of submitting a claim and shorten the amount of time it takes for the municipality to respond, and
- Strengthen the technical skills and capacity within the municipality to use ICT tools for citizen engagement.
