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.

- NASA awarded a contract to startup Axiom Space to attach a "habitable commercial module" to the International Space Station.
- The project will also include a research and manufacturing module.
- The move is a major step in NASA's years-long push to privatize.

After that, the trip sounds pretty comfy:</p><p>"There will be wifi," Suffredini <a href="https://www.nytimes.com/2018/06/09/style/axiom-space-travel.html" target="_blank">told the New York Times</a> last year. "Everybody will be online. They can make phone calls, sleep, look out the window. [...] The few folks that have gone to orbit as tourists, it wasn't really a luxurious experience, it was kind of like camping. [...] Pretty soon we're going to be flying a butler with every crew."</p>
A render of the ISS tourist experience.

The other elements of the five-point plan include efforts to make station and crew resources available for commercial use through a new commercial use and pricing policy; enable private astronaut missions to the station; seek out and pursue opportunities to stimulate long-term, sustainable demand for these services; and quantify NASA's long-term demand for activities in low-Earth orbit."</p>
NASA's push to privatize the ISS<p>When a Russian rocket launched the first module of the ISS into space in 1998, NASA expected the space station to operate for about 15 years. But the agency has extended the life of the ISS twice, with funding currently set to expire in 2024. NASA spends between $3 and $4 billion per year operating and shuttling astronauts to and from the station. That's a decent chunk of the agency's $22.6 annual budget. What's more, the "major structural elements" of the ISS are certified only through 2028.</p><p>Meanwhile, NASA has been eyeing other projects, namely: putting humans back on the moon in 2024 and establishing a lunar presence. So, to save and redirect money, the agency has been starting to hand over the aging space station to the private sector, which could use it for commercial research and space tourism.</p><p>But some have questioned the move to privatize the ISS, including NASA's own inspector general, Paul K. Martin.</p><p>"An obvious alternative to privatization is to extend current ISS operations," Martin wrote in a <a href="https://oig.nasa.gov/docs/CT-18-001.pdf" target="_blank">2018 report</a>. "An extension to 2028 or beyond would enable NASA to continue critical on-orbit research into human health risks and to demonstrate the technologies that will be required for future missions to the Moon or Mars."</p>
Image: Axiom Space<p>Martin noted that "research into 2 other human health risks and 17 additional technology gaps is not scheduled to be completed until sometime in 2024," meaning that any slip-ups in the process would mean such research might go uncompleted. He also wrote that it's "questionable" whether the private sector could turn a profit on the ISS without "significant" government funding. The Institute for Defense Analyses, a federally funded research and development center, <a href="https://docs.house.gov/meetings/SY/SY00/20180517/108302/HHRG-115-SY00-Wstate-LalB-20180517.pdf" target="_blank">also found</a> that it "is unlikely that a commercially owned and operated space station will be economically viable by 2025."</p><p>The implication is that, if the ISS is handed over to the private sector, taxpayers could end up indirectly supporting space tourism for the ultra-rich. Whether that's worth any of the research benefits that might come from the ISS post-2024 is anybody's guess.</p><p>As the ISS enters its final years, China <a href="http://www.xinhuanet.com/english/2019-10/17/c_138479514.htm" target="_blank">plans</a> to complete construction of a manned space station in 2022.</p>
The coronavirus pandemic has brought out the perception of selfishness among many.
- Selfish behavior has been analyzed by philosophers and psychologists for centuries.
- New research shows people may be wired for altruistic behavior and get more benefits from it.
- Crisis times tend to increase self-centered acts.
