Figure of the week: Africa is home to the 10 fastest growing cities in the world

The United Nations Department of Economic and Social Affairs projects that the world’s 10 fastest growing cities, between 2018 and 2035, will all be in Africa. The visualization below first maps the location of the fastest growing cities in the world with a population greater than 2.5 million. Interestingly, many of the fastest growing African cities are specifically located on the Gulf of Guinea including Lagos, Abuja, Abidjan, Doula, and Kumasi.

Wildfires can’t cool hot real estate markets | Grist

More people than ever want to live on the wild edges of Western cities, despite the risk wildfires pose to their homes. A recent study by researchers at the University of Nevada, Las Vegas, found that wildfires drive down real estate prices only in the immediate aftermath of a disaster. Home prices in burned areas typically rebound to pre-fire levels within one to two years.

……

Yet developers will continue to build in high-risk areas as long as there’s a demand. Residential growth in forested areas across the United States has exploded in recent years, from an estimated 12.5 million housing units in 2000 to 44 million by 2010. “We should be worried about that,” said University of Nevada, Las Vegas, research economist Shawn McCoy, who led the study. “The societal costs of wildfire will increase, because people continue to develop there. They know that those homes will sell regardless of the risk.”

….

The researchers found that the value of homes within sight of burn scars did dip after a fire and was slower to rebound. But even there, homebuyers’ awareness of fire risk didn’t impact their willingness to invest in those properties. Overall, housing values in the high-risk zones dropped in the year following a wildfire, but rebounded to pre-fire prices in one to two years.

….wildfire suppression accounts for 52 percent of the Forest Service’s budget; by 2021, it’s projected to increase to 67 percent….

Rising seas could wipe out $1 trillion worth of U.S. homes and businesses | Grist

 

Some 2.4 million American homes and businesses worth more than $1 trillion are at risk of “chronic inundation” by the end of the century, according to a report out Monday. That’s about 15 percent of all U.S. coastal real estate, or roughly as much built infrastructure as Houston and Los Angeles combined.

The sweeping new study from the Union of Concerned Scientists is the most comprehensive analysis of the risks posed by sea level rise to the United States coastal economy. Taken in context with the lack of action to match the scale of the problem, it describes a country plowing headlong into a flood-driven financial crisis of enormous scale.

As California’s largest lake dries up, it threatens nearby communities with clouds of toxic dust – The Verge

Dying lakes release dust, often polluted dust, that is literally killing people who can’t afford to move.

Though we often think of lakes as permanent landmarks, global warming, irrigation, and our constant thirst threaten these resources around the world. Terminal lakes like the Salton Sea, bodies of water that have no natural drain, are particularly vulnerable. Iran’s Lake Urmia — once the largest body of water in the Middle East — has shrunk by almost 90 percent over the last 30 years; Africa’s Lake Chad is also 90 percent smaller than it was in the 1960s; and Kazakhstan’s Aral Sea, once the fourth largest salt lake in the world, has practically been wiped off the map.

When these lakes evaporate, they can upend industries and erase surrounding communities. For residents near the Salton Sea, the most pressing problem is the threat of toxic dust. The receding Salton Sea will reveal at least 75 square miles of playa, the lake bed that the water once hid. When that soil dries, it will begin to emit dust laced with industrial runoff from the surrounding farms: up to 100 tons of dust could blow off the playa daily. If it isn’t captured, that dust will push the area’s asthma crisis from bad to dire. The Salton Sea is a dust bomb that has already begun going off.

Naiipa Art Complex / Stu/D/O Architects | ArchDaily

Worthwhile to go to website and check out the photos.

Text description provided by the architects. Naiipa (Literally means ‘Deep in the Forest’) is a mixed use project consisted of an Art Gallery, Sound Recording Studio, Dance Studio, Restaurants, Coffee Shops, and Office Spaces. It is located on Sukhumvit 46, a small street that connects Rama 4 road to Phrakanong BTS Station on Sukhumvit road. The project is named after the concept of concealing the architecture in the forest as the vision of greenery is expanded by using reflective glass all around.

Something delicious is growing in the ‘sustainability underground’ | GreenBiz

This urban hydroponics farm is in refurbished WWII bunkers just 100 feet under the swarming, grubby streets of Clapham, in South London. Next time I hear that 1970 Motown line, “War, what is it good for?” followed by the response, “Absolutely nothing,” some part of my brain will protest: “Hydroponics!” In effect, what Growing Underground does is to flip vertical farming on its head. Instead of going up, it goes down. With U.K. supermarkets recently forced to ration vegetables in the wake of poor harvests…………

The headline: “Paris to turn a third of its green space into urban farms.”

The piece continued, “It all started when the city’s mayor, Anne Hidalgo, who was elected in 2014, declared her intention to make Paris a greener city. The Paris government responded to her call in 2016 by launching Les Parisculteurs, which aims to cover the city’s rooftops and walls with 247 acres of vegetation by 2020. A third of the green space, according to its plan, should be dedicated to urban farming.”

The city’s deputy mayor, Pénélope Komitès, noted, “Paris not only intends to produce fruit and vegetables but also (plans to) invent a new urban model. … We have seen a real craze among Parisians to participate in making the city more green. Urban agriculture is a real opportunity for Paris. It contributes to the biodiversity and to the fight against climate change.”

Bringing Some New Ideas to an Older Part of Amsterdam – Next City

 

By night, Reguliersdwarsstraat is one of the busiest streets in central Amsterdam. A hub for the city’s LGBTQ community, its restaurants, bars and clubs attract large numbers of locals and tourists alike. By day, however, the picture is markedly different. Despite being just steps away from Amsterdam’s famous floating flower market, the area has struggled to attract the daytime crowds.
