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?

Securing land tenure with smartphones

More than 1,000 years.

That’s how long recent estimates suggest it would take in some developing countries to legally register all land – due to the limited number of land surveyors in country and the use of outdated, cumbersome, costly, and overly regulated surveying and registration procedures.

But I am convinced that the target of registering all land can be achieved – faster and cheaper. This is an urgent need in Africa where less than 10% of all land is surveyed and registered, as this impacts securing land tenure rights for both women and men – a move that can have a greater effect on household income, food security, and equity.

The question remains, how can we register land and secure tenure at scale?

Perhaps one of our answers can be found in rural Tanzania where I recently witnessed the use of a mobile surveying and registration application. In several villages, USAID and the government of Tanzania are piloting the use of the Mobile Application to Secure Tenure (MAST), one of several (open-source) applications available on the market. DFID, SIDA, and DANIDA are supporting a similar project.

The process of mobile land surveying and registration goes like this:

Debunking myths about migrants, refugees, and jobs in South Africa

As one of the most urbanized African countries and the largest economy in Southern Africa, South Africa is a popular and important destination for migrants and refugees from all over Africa, and increasingly, from parts of Asia.

South Africa has over 4 million migrants, including over 300,000 refugees and asylum-seekers. The latest South African census data estimates that migrants account for over 4% of the country’s population. Contrary to what some may think, immigrant workers have had a positive impact on local employment and wages in South Africa, according to a new World Bank study.

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.

Urban 20: Cities at the center of local solutions to global development challenges

Ede Ijjasz-Vasquez's picture
 

With the world becoming more urban than ever before, cities are at the core of the global development agenda. They play such a pivotal role in addressing global challenges and improving citizen’s lives that the battle against poverty and climate change to build inclusive, resilient, and sustainable communities will be won or lost in cities.
 
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. There is an urgent need to bring cities’ leadership, knowledge, and expertise to the center of global conversations on sustainable urban development.  

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.

Quantifying public spaces for better quality of urban assets

A stage is now ready for public urban spaces.
 
“By 2030, provide universal access to safe, inclusive and accessible, green and public spaces, particularly for women and children, older persons and persons with disabilities” – Sustainable Development Goal (SDG) 11.7
 
The importance of public space is highlighted in international agendas, and diverse organizations started piloting the role of urban planning and public spaces in cities.


For instance,  UN Women launched the Safe Cities and Safe Public Spaces report, which enhanced public spaces designs with better lighting and CCTVs to prevent and respond to sexual violence against women. There are more onboard, including the Food and Agriculture Organization (FAO) on sustainable forestry  and the World Health Organization (WHO) on green spaces and health. The World Bank has also committed to enhancing public spaces across cities including Karachi, Chongqing, and Dhaka.

To realize these collective efforts, better measurement tools are vital to follow up with evidence-based approaches. On July 11th, 2018, UN-HABITAT and ISOCARP held a side event during the High-Level Political Forum at the UN, titled “Quantifying the Commons.” While speakers from various organizations including the World Bank presented their works, three key questions were raised regarding our future steps:

Five ways to do better post-disaster assessments

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?

When disasters displace people, land records and geospatial data are key to protect property rights and build resilience

Droughts, floods, hurricanes, and other disasters displaced over 24 million people in 2016. When people leave their homes behind, land records offer critical protection of their property rights. This is crucial, as land and homes are usually the main assets that people have. Land and geospatial information is key to ensure that land records are comprehensive and secure.

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.

Comprehensive land and geospatial systems can secure the resilient recovery of economic activities – 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.

Livability to start with the neighborhood – Singapore's urban practice (Part 1/2)

Xueman Wang's picture
For more than 30 years, Madam Toh has lived in Bukit Batok, a Singapore public housing town that accommodates more than 110,000 residents. Their flat was constructed by the Singapore Housing and Development Board – known as “HDB” – which provides public housing for 82% of Singapore’s residents.
 
While working at the World Bank’s Singapore Infrastructure and Urban Hub, I was fortunate to meet Madam Toh, who, together with her husband, raised their three children in their three-bedroom flat. When asked about her experience living in an HDB neighborhood, her immediate reactions were that it was both “convenient” and “comfortable” – “I can get everything I need within 10 minutes on foot.”
 
She is now 64 years old and takes a daily 10-minute walk to the metro train station (Mass Rapid Transit, or “MRT”) via a linkway – an activity she likes because the covered footpath seamlessly connects her home and the community’s amenities, making them excellent shelters from the rain or sun for pedestrians.

After exploring several of Singapore’s neighborhoods, I found that they offer “down to earth” examples of livability and showcase excellent integrated urban design qualities.

5D Compact City Framework
 
A good method I’ve come across for explaining how Singapore has enhanced its livability is through the “5D” Compact City Framework:  

Livability to start with the neighborhood – Singapore's stories (Part 2/2)

Xueman Wang's picture
In the first part of this blog, I introduced the 5D framework and discussed the first 2Ds – Density and Diversity in the context of Singapore’s public housing neighborhood, i.e. HDB towns. In the second part of the blog, I will share the observations of how the HDB neighborhoods reflect the other 3Ds – Destination, Distance, and Design. 
 
To improve destination access, Singapore has increased neighborhood walkability and encouraged residents to use public transportation by putting in place the Walk2Ride program. This government policy ensures that public linkways are provided from MRT stations (Mass Rapid Transit, or “MRT”) up to a radius of 400m, or ¼ mile, to bus stops, public amenities, and public housing.
 
“Comfortable” and “walkable” access to public transportation is just one of the many examples that Singapore has done for its neighborhoods, and the total length of Singapore’s covered walkways has now hit 200km!
 
In order to decrease distance to transit, Singapore encourages people to cycle, which helps resolve the issue of the first and last mile connectivity to public transportation. Many MRT stations and bus interchanges provide multi-level bicycle racks as part of cycling infrastructure to make the city cycle-friendly. In fact, starting July 2016, any new constructions for schools, commercial, retail and business parks (up to a certain scale) must put in place a Walking and Cycling Plan to ensure the public space has adequately incorporated the design that facilitates walkability and cycling.

For the last “D”, let’s explore Singapore’s various elements of urban design that create the city. I think neighborhoods are a key part of Singapore’s vision of being a city in a garden. Singapore is compact, but the government is making a tremendous effort to bring the natural environment to the residents.
