10 ways cities are tackling the global affordable housing crisis

Research finds that only 10% of cities worldwide are affordable.

The unprecedented rate of urbanization across the world has led to increased demand for good, affordable housing.


A recent survey revealed that of 200 cities polled around the globe, 90% were considered unaffordable when applying the widely-used standard of average house prices being more than three-times median income.

Affordability is not just about the ability to buy or rent a home, but also about being able to afford to live in it. This definition of affordability goes beyond meeting expenses related to operations and maintenance, taking into consideration transport, infrastructure and services. If a home is economical enough to buy and maintain but located too far from work or school, it cannot be said to be affordable.

The factors contributing to a lack of affordability vary from city-to-city, but broadly include housing costs rising faster than incomes, the supply of houses not keeping up with demand, scarcity of land, and demographic changes such as population growth, ageing and shifts in household composition.

To understand the challenge more holistically, the World Economic Forum on 6 June launched a new report, Making Affordable Housing a Reality for Cities. It provides a comprehensive overview of affordable housing challenges across the housing value chain. The report identifies factors that affect housing affordability beyond the direct costs of purchase and maintenance – including location, housing type, access to social infrastructure, the legal and regulatory environment and the state of financial markets.

The report recommends a systematic approach to addressing the affordable housing crisis, while highlighting how a range of cities are finding solutions. Here are ten ways that cities around the world are addressing the housing challenge:

1. Land Acquisition: Tradeable Land Quotas – Chengdu and Chongqing

In China, local governments have limited authority to expropriate rural land for new housing. Chongqing and Chengdu are experimenting with "tradable land quotas", through which developers are permitted to construct new housing on the periphery of a city in return for opening up additional land for cultivation beyond city boundaries.

2. Land Use: Communities Plus Program – Sydney, New South Wales

The state government of New South Wales, Australia, is partnering with the private sector and non-governmental and community housing groups to develop or renovate 23,000 social housing units in neighborhoods that need renewal, along with 500 affordable- and 40,000 private dwellings. Proceeds are re-invested in social housing, community facilities and public space. Housing assistance is linked to participation in education, training or local employment.

3. Repurposing Vacant Property: Motel Conversion Ordinance – Los Angeles

Los Angeles recently passed a law allowing motels to be converted into "permanent supportive housing" for the homeless, regardless of current zoning requirements. This is typically quicker and cheaper than new construction, as it involves only adding small kitchens to the motel rooms.

4. Financing: Urban Wealth Fund – Hamburg and Copenhagen

Hamburg and Copenhagen have improved housing supply by pooling publicly owned assets into an "Urban Wealth Fund" that partners with the private sector to deliver projects. Sharing risks and benefits aligns the interests of these stakeholders and can streamline infrastructure development, planning and land-use regulations.

5. Construction Productivity: Mayor's Construction Academy – London

Shortages in construction skills can drive up labour costs and, in turn, housing construction costs. London has established the Mayor's Construction Academyto accredit training providers, strengthen coordination between training providers and construction employers, and provide funding to upgrade training equipment and premises – making the city's skills training more useful to the construction industry, and more attractive for young people.

6. Design: Green Roof Initiative – Denver

Denver's "Green Roof initiative" requires buildings taller than 25,000 square feet to have green roofs or solar panels – including affordable housing projects. While upfront costs will increase, lower-income communities should benefit in the long term from lower levels of air- and water pollution, as well as cheaper energy bills.

7. Construction Material: Glass Fibre Reinforced Gypsum – India

After a decade of research, the Indian Institute of Technology in Madras has proposed a building system using Glass Fibre Reinforced Gypsum (GFRG) panels– low-cost, prefabricated panels made using gypsum waste from fertilizer plants – using minimal concrete and steel, and no bricks. The Indian government has approved standards for structures of up to 10 storeys high. Thermal resistance reduces the need for air conditioning. GFRG has been dubbed a green material by the United Nations Framework on Climate Change.

8. Eligibility: Criteria for Social Housing – Dupnitsa, Bulgaria

Dupnitsa, Bulgaria, constructed 150 social housing units with eligibility restricted to those who own no property and earn an income under a specified limit. Applicants were ranked based on their employment status, education level, age and number of children.

9. Tenure Systems: Multiple tenures for housing – Bristol, UK

Bristol, UK, is constructing 161 homes on a former primary school site with six different types of tenure. A housing association, community investment company and private investor have worked together to create this model, in which some houses will be sold at market price and others made available through tenures, including shared-ownership and rent-to-buy. The scheme is aimed vital workers who are being priced out of the city.

10. Home ownership: Melbourne Apartment Project – Melbourne, Australia

The Melbourne Apartment Project - The Barnett Model Development in North Melbourne is a privately-funded development supported by the University of Melbourne, Melbourne City Mission, Resilient Melbourne and the City of Melbourne. As part of the scheme, six of 34 apartments are being sold at market rate to subsidize the sale of the other 28 to social housing tenants through a "deferred second mortgage" model that reduces the necessary deposit and repayments. A similar project in Toronto, "Options for Homes", has delivered over 6,000 affordable homes in 20 years.

Addressing the housing affordability challenge requires systematic changes. City governments must streamline their regulatory landscapes and enable transparent land acquisition, emphasize property rights over title, develop a rental regulatory framework to protect tenants as well as landlords, encourage mixed-income and mixed-use housing developments, enable more innovative financing models in developing new homes or upgrading existing homes and encourage skill-building in the construction industry.

The private sector must embrace innovative mechanisms to finance development and help establish the creditworthiness of those looking to improve their housing situation. Employers need to work with communities to provide affordable housing for employees, or help with housing costs through loans, subsidies or mortgage deals. Private developers need to invest in sustainable design concepts to create energy-efficient housing, and improve productivity by mainstreaming 3D Printing, prefabricating components, and using alternative materials and advanced automated equipment.

The non-profit sector also has a key role to play in working with housing providers to implement alternative tenure models, while supporting advocacy efforts, formulating policy and providing technical support, information and know-how to developers and homeowners.

Robot pizza delivery coming later this year from Domino's

The pizza giant Domino's partners with a Silicon Valley startup to start delivering pizza by robots.

Technology & Innovation
  • Domino's partnered with the Silicon Valley startup Nuro to have robot cars deliver pizza.
  • The trial run will begin in Houston later this year.
  • The robots will be half a regular car and will need to be unlocked by a PIN code.

Would you have to tip robots? You might be answering that question sooner than you think as Domino's is about to start using robots for delivering pizza. Later this year a fleet of self-driving robotic vehicles will be spreading the joy of pizza throughout the Houston area for the famous pizza manufacturer, using delivery cars made by the Silicon Valley startup Nuro.

The startup, founded by Google veterans, raised $940 million in February and has already been delivering groceries for Kroger around Houston. Partnering with the pizza juggernaut Domino's, which delivers close to 3 million pizzas a day, is another logical step for the expanding drone car business.

Kevin Vasconi of Domino's explained in a press release that they see these specially-designed robots as "a valuable partner in our autonomous vehicle journey," adding "The opportunity to bring our customers the choice of an unmanned delivery experience, and our operators an additional delivery solution during a busy store rush, is an important part of our autonomous vehicle testing."

How will they work exactly? Nuro explained in its own press release that this "opportunity to use Nuro's autonomous delivery" will be available for some of the customers who order online. Once they opt in, they'll be able to track the car via an app. When the vehicle gets to them, the customers will use a special PIN code to unlock the pizza compartment.

Nuro and its competitors Udelv and Robomart have been focusing specifically on developing such "last-mile product delivery" machines, reports Arstechnica. Their specially-made R1 vehicle is about half the size of a regular passenger car and doesn't offer any room for a driver. This makes it safer and lighter too, with less potential to cause harm in case of an accident. It also sticks to a fairly low speed of under 25 miles an hour and slams on the breaks at the first sign of trouble.

What also helps such robot cars is "geofencing" technology which confines them to a limited area surrounding the store.

For now, the cars are still tracked around the neighborhoods by human-driven vehicles, with monitors to make sure nothing goes haywire. But these "chase cars" should be phased out eventually, an important milestone in the evolution of your robot pizza drivers.
