Global positioning systems (GPS), real time traffic maps, accurate weather forecasts, Uber, self-driving cars… Geospatial data is on full display 24/7 throughout the world these days.  It’s like nothing we have seen before. But none of this would be possible without the underpinning role of the government.

“Geospatial,” or location-based data has existed for hundreds of years – for example, in street and topographical maps. What’s different is how quickly new information is being gathered and the more sophisticated analytics that is being applied to it, thanks to technological advances.

What was once information only found in the domain of government, military, and select private sector, even up to the 1980s and 90s, has come into broad use over the last 20 years. With the increase of mobile technology and communications, handheld smart phones have democratized mapping, moving geospatial technology into the hands of every individual.

This summer, some tens of millions of people in the U.S. traveled to see the total solar eclipse, including a co-author of this blog. Not only was the eclipse amazing – but the drive back from Tennessee to Washington, D.C. showed the integration and impact of geospatial information in our daily lives.
 

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

Sarah Elizabeth Antos's picture

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.

The relationship between poverty and disability goes both ways: disability increases the risk of poverty, and the conditions of poverty increase the risk of disability.

Yet, little attention has been given to the employment readiness of persons with disabilities. This is of concern given that the employment rates of persons with disabilities are a third to half of the rates for persons without disabilities, with unemployment rates as high as 80%-90% in some countries.

Disability is a complex, evolving, and multidimensional concept. Currently, it is estimated that 15% of the world population experiences some form of disability, with prevalence rates higher in developing countries. As opportunities for sustainable income generation are directly tied to a person’s access to finance, markets, and networks, persons with disabilities usually face significant challenges in accessing these, due to:

  • non-inclusive regulations and policy,
  • lack of resource allocation,
  • stigma and societal prejudice,
  • low educational participation, and
  • inability to access their own communities and city spaces.
To continue building inclusive cities, research tells us that countries cannot achieve optimal growth by leaving behind a large group of their citizens – persons with disabilities – with economic losses from employment exclusion ranging from 3 to 7 % of the GDP. We also know that when you combine gender and disability, the challenges facing women with disabilities compound. Women with disabilities are more likely to earn less than men with disabilities and they are affected by inaccessible sanitation, smaller social and professional networks, and gender-based violence – see, for example, labor force data from the UK.

We need to do much more to ensure that women with disabilities are mainstreamed into projects that seek to empower women as entrepreneurs and change agents.

Expanding equitable opportunities for persons with disabilities is at the core of the World Bank’s work to build sustainable and inclusive communities. So, what might a disability-responsive moonshot look like for development projects addressing work for persons with disabilities? Here’s what we’re doing at the World Bank:

Ideas Box: the library that promotes literacy and builds disaster resilience—a Q&A

Barbara Minguez Garcia's picture


Over the last two weeks, we’ve witnessed three hurricanes in the Caribbean and Gulf of Mexico as well as a magnitude 8.1 earthquake in Mexico, killing people and destroying homes. They serve as a reminder that natural hazards pose a greater threat to our lives and livelihoods than we may think.

Dealing with rising disaster risks requires greater efforts with smarter approaches—ones that can help vulnerable people and communities better prepare for, and recover from, disasters. Libraries Without Borders (BSF), an international organization that expands access to information, education, and cultural resources to vulnerable people around the world, knows that very well.

In 2010, BSF was building libraries in Haiti when the well-known earthquake struck. At the time, local partners asked BSF to help them create information and cultural access points in refugee camps. This experience led to the development of the “Ideas Box," an innovative tool that provides vulnerable communities in disaster-prone areas with access to information, education, and cultural resources.

Last week, on the International Literacy Day, I talked to BSF’s Director of Communications and Advocacy, Katherine Trujillo, about the Ideas Box, as well as how their innovative ideas and actions have helped promote literacy and build resilience in disaster-hit communities.

The “human scale” in public urban areas

"If you lose the human scale, the city becomes an ugly place," said Joan Clos, Executive Director of the UN-HABITAT at the Habitat III Conference last month. But more than being "ugly," the lack of good public urban spaces, such as open spaces, parks, and public buildings, often contribute to low livability in many of the world's congested and polluted cities. In fact, the importance of the issue received recognition in SDG 11, Target 7, which calls for the provision of “universal access to safe, inclusive and accessible, green, and public spaces, in particular for women and children, older persons, and persons with disabilities,” by 2030.
 
Global experience shows that disconnected, underutilized areas in urban settings can, instead, be opened up to a variety of uses to allow for improved social inclusion, social mixing, civic participation, recreation, safety, and a sense of belonging, ultimately contributing to urban prosperity. Well-designed and well-managed public spaces also offer benefits to environmental sustainability, transport efficiency, and public health improvements, and can equally serve women, the disabled, and people of all ages.

The importance of good urban spaces was the topic of an international workshop—“Vitalizing Cities with Public Space”—held in Seoul on November 14-17, 2016 and co-hosted by the Korea Research Institute of Human Settlements and the World Bank’s Urbanscapes Group. Eight cities from around the world—Seoul, Singapore, Buenos Aires, Chongqing, Kakamega, Zanzibar, Astana, and Tashkent—participated to discuss challenges and opportunities for better urban planning and design.

What the New Urban Agenda tells us about building inclusive cities

Charlotte McClain-Nhlapo's picture
 
Over a billion people—about 15% of the world’s population—have disabilities. Almost 80% of them live in the developing world, which is undergoing rapid urbanization.

While urbanization brings people closer to new economic and sociocultural opportunities, persons with disabilities still face a range of constraints in many cities, such as inaccessible buildings and public spaces, limited transportation options, inaccessible housing, and barriers in using technology-enabled virtual environments.

These urban constraints have a significant impact on those living with disabilities in terms of mobility, ability to engage in education and skills development, employability and income generation, and larger social and political participation.

Therefore, urban development must acknowledge and plan for the needs of a diverse population which includes persons with disabilities. And there is no better time than now to make that happen.

Information and communication technology (ICT) has expanded the frontiers of connectivity and communication. 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 local governments are getting creative in using this technology to reach out to and engage with their citizens.

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:
  1. Increase citizen participation for evidence-based decision-making,
  2. Reduce the cost of submitting a claim and shorten the amount of time it takes for the municipality to respond, and
  3. Strengthen the technical skills and capacity within the municipality to use ICT tools for citizen engagement. 

Retrofitting: A housing policy that saves lives

When a hurricane, earthquake or other natural disaster strikes a poor country, families too often suffer a double tragedy: the loss of loved ones and their most valuable (and sometimes only) asset, their home. In the aftermath of the 7.0 magnitude earthquake in Haiti in 2010, which killed more than 260,000 people, 70% of asset losses were related to housing. Ecuador faces billions of dollars in reconstruction costs from last April’s 7.8 earthquake, which killed 900 and injured almost 28,000. If Peru were hit by an 8.0-degree earthquake, an estimated 80% of potential economic losses would involve housing.
 
And while nature’s fury does not distinguish between urban and rural areas, a large majority of disaster losses are concentrated in cities, where they disproportionately affect the poor. This creates a great challenge for low and middle-income countries.  In Latin America and the Caribbean, 200 million people—1/3 of the population—live in informal settlements, where most dwellings don’t comply with construction codes and home insurance is non-existent. Perhaps unsurprisingly, LAC’s informal districts also account for the majority of disaster-related deaths in the region.
 

Five ways to increase citizen participation in local waste services

Web platforms, apps, and citizen surveys are changing how solid waste management services are conducted globally and showing that waste infrastructure alone is simply not enough. These interactive platforms provide incentives, quantify actions, and increase pressure on service providers, and thereby improve waste management with greater citizen engagement.
 
The World Bank recently hosted five individuals representing organizations and projects that use information and communications technology (ICT) to engage citizens with local waste services. Their varied approaches reveal incentive models that effectively lead to strategic behavior change.

Using GIS to Manage the Urban Ecosystem

Henry Jewell's picture

Growing up on a farm meant I spent very little time in cities. I felt more at home when surrounded by green than grey. As a kid, I saw cities as noisy, bright, busy and quite frankly, confusing. I always thought to myself why would anyone want to live in them? However, when I grew up, I moved to a city to take advantage of the opportunities it provided. I am not alone. More than 50 percent of the world’s population lives in cities and this number will rise. Cities are hubs of productivity, innovation and vast human capital; but once you live in them you begin to see that they are like any other ecosystem: complex and fragile, whose balance can be easily disturbed. With many cities rapidly growing and evolving, how do you manage this increasing complexity without destroying the ecosystem?

GIS Image.  Source - University of Texas at DallasGeographical Information System (GIS) techniques have proven successful in mapping, analyzing and managing natural ecosystems. It is now time to make use of the same technology to manage, model and design our expanding global system of cities. GIS consists of a proven set of tools that can provide information to leaders at the local and national level to facilitate evidence-driven decision making. It allows us to move beyond 2D paper maps and incorporate everything that lies below, above and around a city to create a 3D digital representation of the city’s ecosystem. By integrating this information into the planning process, it will hopefully lead to harmonized planning across sectors. For example, integrated transport and land use planning and development will allow for economic, social and environmental benefits. More sectors can then be incorporated, with this integration not only happening within the city limits but including the urban periphery, where a lot of urban expansion is currently occurring. This holistic view will allow planners to make cities more livable.
