Climate Crisis: Solar-Powered Oasis to Feed Desert Cities

https://i2.wp.com/f.fastcompany.net/multisite_files/fastcompany/imagecache/slideshow_large/slideshow/2014/08/3034601-slide-s-6-a-solar-powered-oasis.jpgDesertification is one of the biggest threats associated with Climate Change. In places like North Africa and the Middle East, where countries already import up to 90% of their food, the spread of the desert due to increasing temperatures and diminished rainfall is made worse by the fact that cities in the region continue to grow. It’s a situation that is getting more expensive and energy-intensive at a time when things need to be getting more cost-effective and sustainable.

Luckily, a team of architects hopes to create a new agricultural system that could grow and deliver food in the desert. It’s called OAXIS, a conceptual design for a modular set of prefab greenhouses, covered in solar panels, which would extend from a city into the desert. The design of the buildings aims to keep out intense summer heat while the solar panels would power the rest of the building’s infrastructure and send extra energy back into the city.

https://i0.wp.com/a.fastcompany.net/multisite_files/fastcompany/imagecache/slideshow_large/slideshow/2014/08/3034601-slide-s-3-a-solar-powered-oasis.jpgConceived by Forward Thinking Architecture, a Barcelona-based firm, the concept seeks to combine flexibility with a minimal carbon footprint. Towards this end, they chose to forgo usual transportation and create a unique conveyor system that would deliver produce without the use of any fossil fuels. The conveyor belt would be underground so it could keep running in a straight line even if buildings were in the way.

Inside the prefab greenhouses, farmers would grow crops like tomatoes, lettuce, and strawberries using a hydroponic system that can reduce fertilizers and pesticides and save 80% of the water used in traditional agriculture, in part by recycling and reusing it. As for where the water comes from, the designers suggest that groundwater could supply the farm’s needs, but many Middle Eastern countries already rely on desalination.

https://i0.wp.com/a.fastcompany.net/multisite_files/fastcompany/imagecache/inline-large/inline/2014/08/3034601-inline-i-1-a-solar-powered-oasis.jpgIdeally, desert populations would be small enough that the region’s sparse rainfall could support local crops. But that’s not the reality. In addition, a small part of the recycled water would also be used to create an outdoor garden for education. As architect Javier Ponce, principal and founder of Forward Thinking Architecture, explained:

We thought it cannot only be a farming-only building, it must have a pedagogical approach and have to be attractive in order to become a biodiversity hub which can be visited by the local people and visitors… The cities should be smaller, denser, and compact, but this is not the current situation for some of the Arabian peninsula cities since they have exponentially grown and attract more people and workers. There has been a rapid urbanization in the area since the middle of the 20th century.

The project, he hopes, could help supply food as climate change makes the situation even more challenging. Already, countries in the worst-affected regions are desperately looking for solutions. For example, Qatar has already invested hundreds of millions in a plan to grow as much local food as possible by 2030. Other countries in the region, like Kuwait, Dubai, Abu Dhabi, Jordan, and the desert-locked Saudi Arabia are expected to follow.

https://i0.wp.com/e.fastcompany.net/multisite_files/fastcompany/imagecache/slideshow_large/slideshow/2014/08/3034601-slide-s-7-a-solar-powered-oasis.jpgThese regions in particular have felt the pressure brought on by the escalating price of importing food. This pressure is exacerbated due to the disappearance of peak oil, which accounted for the vast majority of this region’s wealth. However, the project has farther-reaching implications, as Climate Change threatens to turn much of the world’s arable land into dry, drought-ridden plains.

At the same time, it takes into account the need to reduce reliance on water and fossil-fuels. As our population continues to skyrocket, a smarter and more sustainable use of available resources are always needed. As Ponce explained:

The OAXIS project is an alternative or complementary way to respond to the food insecurity and water scarcity of the region in a self-sufficient way. It aims to help reduce the food imports to feed part of the people in a nearby future based on renewable energies.

Climate Crisis: London’s River Village and Pools

https://i0.wp.com/i.telegraph.co.uk/multimedia/archive/02192/london-from-space_2192333k.jpgOne of the greatest challenges facing future urban planning is the very real prospect of running out of land. In addition to urban sprawl encroaching on neighboring farmlands, the concentration of people at the core eventually creates a situation where open spaces become incredibly scarce. Luckily, the city of London – one of the largest and most densely populated cities in the world – is coming up with some innovative solutions.

For starters, the city is developing the area around some former dockyards in East London to accommodate a floating neighborhood. Borrowing from similar projects that were initiated in the Netherlands to prepare for rising sea levels, London’s new river-based housing program is designed to place housing in the one spot that hasn’t been converted to high-rise apartments or suburban dwellings.

https://i0.wp.com/b.fastcompany.net/multisite_files/fastcompany/imagecache/slideshow_large/slideshow/2014/08/3034075-slide-s-3-ondon-is-planning-its-first-floating-village-to-make-room-for-more-housing.jpgExperts from the Netherlands are helping to plan the new “floating village,” which will include 50 floating homes around a neighborhood square that comes complete with floating restaurants, offices, and shops, and possibly a floating swimming pool (more on that below). A floating walkway will lead back to land, where the city plans a much larger development with tens of thousands of new homes.

Earlier in its history, the area, known as the Royal Docks, served hundreds of cargo and passenger ships each day. The three docks were the largest enclosed docks in the world – 250 acres of water and over 1000 acres of land – and got more use than any other port in London. But they haven’t been in use for the last several decades, and that’s why the city wants to transform the area.

https://i2.wp.com/b.fastcompany.net/multisite_files/fastcompany/imagecache/slideshow_large/slideshow/2014/08/3034075-slide-s-1-ondon-is-planning-its-first-floating-village-to-make-room-for-more-housing.jpgAs Richard Blakeway, the city’s deputy mayor for housing, land and property

With demand for new homes in London soaring, we need to put every scrap of available land to the best possible use. Tens of thousands of new homes, workspace, leisure, and cultural facilities are being developed . . . The ‘Floating Village’ will be yet another draw, restoring London’s docklands to their former glory as a centre of enterprise and bringing jobs, growth, homes and visitors.

On the same front, the city of London is also contemplating turning its river waters into a massive public pools project. Known as the Thames Bath Project, this idea was inspired by similar ideas where swimming pools have been created out of waterways. For example, New York has a project called +Pool, which has raised more than $300,000 in crowd-funding, and looks set for a 2016 launch.

https://i0.wp.com/h.fastcompany.net/multisite_files/fastcompany/imagecache/inline-large/inline/2014/08/3034656-inline-i-1-london-joins-list-of-cities-building-pools-in-their-rivers.jpgThe Thames Baths Project is similar, aiming to create a freshwater lagoon amid the meandering old waterway. The consortium responsible consists of Studio Octopi, Civic Engineers and Jonathan Cook Landscape Architects, all of whom won the competition last year to come up with new river uses. Initially, they hoped to create a pool using water from the Thames that would be filtered and treated.

However, that plan has since been updated and improved to something a little more sanitary. Now, they plan to pump in freshwater, rejected the New York City idea of filtering the water as it enters the pool space because of the concern of sewage. And though London has a major sewage system upgrade planned, the designers are worried it won’t be ready in time to ensure sufficient water quality.

london-poolAs Chris Romer-Lee, director of Octopi, explained:

We’re using freshwater because of the sewage overflows from the aging [Sir Joseph William] Bazalgette sewers. They dump millions of tons of sewage into the river after even the shortest rain storm. A filtration system could work. We’ve been looking at natural swimming pools and the filtering systems they use. But the +Pool filtering system is as yet unproven.

The design calls for floating pontoons with space for three pools –  one large, one medium, and one for paddling. A thick layer of vegetation will mark the edges and a ramp leading off the side will connect swimmers back to firm ground. The $8.5 million plans are still awaiting approval from the city, but, if all goes well, the baths could be completed sometime early in the next decade.

london-pools1The purpose, according to Romer-Lee, is about re-purposing something that would otherwise be forgotten:

We need these baths to reconnect Londoners with their largest public space. The river is used extensively for transporting building materials, passengers and the like but is increasingly becoming something that Londoners look over and don’t engage with.

Meanwhile, Berlin also has a proposal for an open river pool, as does Copenhagen, which actually already has swimming in its harbor. No doubt, it won’t be long before others follow. In fact, the idea of re-purposing public spaces that have fallen into disuse is becoming increasingly popular – not just as a response to sprawl, but as an innovative solution of what to do with infrastructure that has fallen into disuse.

Cities like Detroit, Philadelphia, Washington DC and Hamilton, Ontario and Montreal, Quebec – just to name a few – all might want to consider getting on board with this…

Settling Mars: The Mars Base Challenge 2014

mars-colonyLife on Mars can’t become a reality without some serious design concepts and engineering. And that’s why Thingiverse, in cooperation with NASA’s Jet Propulsion Laboratory, conduct the Makerbot Mars Base Challenge every year. Taking Mars’ extreme conditions into consideration, people are tasked with designing a utilitarian Mars base that can withstand the elements and make settlers feel at home.

The competition opened on May 30th and received some 227 submissions. The challenge brief asked entrants to take into account the extreme weather, radiation levels, lack of oxygen and dust storms when designing their Martian shelters. And the winning entries will each be awarded a MakerBot Replicator 2 Desktop 3D Printer in order to help them fully explore their designs for Martian abodes.

And although the applicants did not always nail the science, their designs have a novelty that has not been seen in some time. This can especially be seen in with this years finalists, which included a design for a Martian pyramid, a modular beehive and a three-tiered Acropolis.

MarsChallengeResultsThe Thingiverse community appears to have been hugely supportive, printing out the designs themselves and offering handy hints in the comment section beneath each entry. Some were dismissed for being impractical; for example, those that would be immediately flattened or kill all of its inhabitants if it were installed on the Martian surface. But one designer, Noah Hornberger, points out:

A toy car does not need fuel because it runs on the imagination of the child who drives it around. So it seems to me that I’m driving my toy car at full speed and you are here telling me what kind of fuel and oil it needs to run. I would rather leave the physics to the right people.

Luckily, that’s what NASA is on hand for – to ensure that it’s not just the mathematicians and engineers that have an interest or a say in our Martian future, but to make sure those designs and dreams that come from the public meet the basic scientific and engineering requirements. Bringing together inspired ideas and realistic needs, here’s how this year’s finalists measured up.

MarsPryamid-4_Feature_preview_featured This Mars structure is designed with resource consumption and allocation in mind, and also takes into account that the majority of activity would be taking place inside the structure rather than outside. As its creator, Valcrow. explained:

High traffic rooms all have ample natural Martian light to help with the crews extended isolation and confinement… This design focuses on looping essential systems into as many multi-functional roles as possible to ensure that the very limited resources are used and reused as much as possible.

This includes food created through a sustainable aquaponics system which would sit at the top of the pyramid, where it can get some light. A mirror-based series of solar panels will be responsible for collecting energy, with a nuclear generator for backup, and water would be stored near the main power center so that it heats up. The whole thing is inspired by the Pyramid of Giza, but unlike that beauty it can be reconfigured for science or engineering tasks and experiments.

Mars_beehiveThis second design, known as the Queen B because of its modular beehive configuration, comes with all the mod cons and home comforts you might expect on Earth – a kitchen, two bathrooms, a garden, and a 3D print lab and decompression room. Its creator, Noah Hornberger, chose a flat-panelled, low-level design that would be cheap and easy to build and allow for less heat energy to be lost. The hexagon shape was chosen for its durability and ability to form modular designs.

Depleted uranium would be used to create laminated panels that would shield out the elements, but would need to be sandwiched between other materials to make it safe for the occupants. An exothermic chemical reactor would meanwhile be used to heat an underground water container, which will provide heat for the basecamp. Excess steam could also power generators to supplement solar power.

Speaking on behalf of his creation, Hornberger said:

I have extrapolated on the idea of a fully functional apartment on Mars with all the modern amenities fitted inside 16-foot-diameter hexagons. I think that to present Mars life to people and actually make it appealing to the public it needs to feel like home and reflect the lifestyle trends of Earth living.

Mars_acropolisAnd last, but not least, there’s the Mars Acropolis – a design that blends materials used here on Earth to create a classic futurist design that looks like it would be at home in the classic Fritz Lang film. Concrete, steel and Martian soil help form the outer wall that protects the population, while carbon fibre, stainless steel, aluminium and titanium would be used to build the main body.

Three greenhouses contain the vegetation and help filter the air and produce oxygen, and there are decompression chambers at the entrance. On level two, residents can park their shuttles before entering the living quarters and labs, while level three acts as the nerve center – with flight operators and observation posts. It’s joined by a huge water reservoir that flows to the first level for purification.

Designer Chris Starr describes the layout as follows:

The structure serves as a mass research facility, to explore and develop means for additional colonization of the planet. Due to the water vapour contained in the Martian atmosphere, that vapour can be harnessed into usable liquid water, where the condensation is collected from the water vapour, which is filtered back into the reservoir.

mars_one2In all cases, the designs draw attention to the fact that any structures intended for life on Mars will have to achieve a balance between resource management, comfort and entertainment, and security against the elements. At this point, there’s no telling exactly what a Martian settlement will look like; but as always, the truth will likely be stranger than fiction.

The Future of Housing: Casa Futebol Concept

casa_futebol_brazilIt’s no secret that Brazil’s decision to host the 2014 World Cup was the source of controversy. With roughly $4 billion spent on renovating and constructing the stadiums needed to host the international event, many wondered why that money could not have been spent addressing other infrastructure concerns – such as providing housing and utilities for its many impoverished citizens.

However, drawing inspiration from the social issues plaguing much of the publicity around the event, a pair of French architects have developed a proposal to re-invent the structures as complexes for low-cost housing. While most of the stadiums constructed for the World Cup will continue to host football matches, Brazil’s local teams stand to draw a fraction of the crowds that attended the event, doing little to assuage concerns of wasted resources.

casa_futebol_brazil-1Other buildings, such as the Arena da Amazonia, face a less certain future. Located in the jungle city of Manaus, the 44,500 seat stadium is perhaps the most contentious of Brazil’s World Cup creations. A local judge proposed converting it into a center for temporary detainees to tackle the city’s overflowing prisons, though this was met with fervent opposition from government officials.

The proposal by Axel de Stampa and Sylvain Macaux is perhaps the most ambitious. Dubbed Casa Futebol, it involves transforming each of the 12 World Cup Stadiums into affordable housing for Brazil’s poor and displaced. As Stampa explained in an interview with Gizmag:

The project covers 12 Brazilian stadiums. There are actually six stadiums where we can colonize the exterior facade. Five of these have an exterior structure composed of concrete and metal columns separated by seven or eight meters (23 to 26 ft). We just have to insert pre-fabricated housing using the existing structures.

casa_futebol_brazil-2The remaining stadiums would see housing modules that are 105 m2 (1,130 ft2) fitted to the interior at the expense of rows of seating, the only difference between these and those receiving exterior additions being the installation process. Conscious of Brazil’s adoration for the world game, the proposal would see the stadiums altered slightly, but continue to host matches with profits going towards ongoing maintenance and construction of the housing.

The project is based on modular pre-fabricated houses. So the only thing that changes is the implantation of the houses… We think that the concept is achievable in all 12 stadiums. You just have to take up some seating and reduce their capacity a little bit.

The team guesses that if converted, the stadiums could each house between 1,500 and 2,000 people per building, and a total of approximately 20,000 across the entire project. This bold proposal for Brazil’s stadiums forms part of a year-long architecture project called 1 week 1 project, where the pair endeavor to produce spontaneous architecture projects every week for one year.

casa_futebol_brazil-4While they don’t have current plans to take the Casa Futebol beyond the concept stage, it is hoped that the project can inspire more socially-conscious approaches to problems of this kind. Combined with 3-D printed housing and other prefab housing projects, this kind of re-purposing of existing infrastructure is a way of addressing the problem of slums, something which goes far beyond the developing world.

The Future of Urban Planning: The Urban Skyfarm

urban-skyfarm-9The world’s population is projected to grow to between 9 and 10 billion people by the middle of the century. What’s more, roughly two-thirds of those people are expected to live in major cities. Coupled with the expected changes caused by Climate Change (i.e. increased drought and less in the way of arable land), and its understandable why urban farms are seen as a means of picking up the slack.

That’s the concept behind the Urban Skyfarm, a concept for a skyscraper that is shaped like a tree and comes with leaf-like decks to provide space for real trees to grow. Currently, most vertical farming operations – like warehouses in Chicago, Kyoto, Singapore and a recent skyscraper built in Sweden by Plantagon – grow plants with ultra-high-efficiency systems under artificial light.

urban-skyfarm-2However, this new design concept from Aprilli Design Studio takes a different approach, using lightweight decks to provide growing space outdoors on the sides of a giant skyscraper. The architects aren’t the first to embrace the trend of sticking greenery on towers, but they may be one of the first to look at how to use the technique to maximize food production. As architects Steve Lee and See Yoon Park explained:

Our version of the vertical farm was intended to become an independent, open-to-air structure which would be purely focusing on farming activities and sustainable functions such as generating renewable energy and performing air, and water filtration.

Designed to mimic the shape of an enormous tree, the Urban Skyfarm uses leaf-like decks to provide 24 acres of space for growing fruit trees and plants. The “trunk” houses an indoor hydroponic farm for greens, and solar panels and wind turbines at the top of the tower provide enough energy to power the whole operation. The design would also capture rainwater and filter it through a constructed wetland before returning it to a nearby stream.

urban-skyfarm-5So in addition to growing food and using rainwater to provide irrigation, the building also was also designed with an eye towards energy independence. The architects envision the project in the middle of downtown Seoul, South Korea:

It seemed to be an ideal place to test out our prototype since the specific area is very dense and highly active and has been suffering for a long time by all sorts of environmental problems resulting from rapid urbanization…With the support of hydroponic farming technology, the space could efficiently host more than 5,000 fruit trees. Vertical farming is more than an issue of economical feasibility, since it can provide more trees than average urban parks, helping resolve urban environmental issues such as air pollution, water run-off and heat island effects, and bringing back balance to the urban ecology.

The design would also provide community gardens, park space, and a farmers market to cater to a demand for fresh, local food in a city where apples can cost more than $20 at local markets.

urban-skyfarm-7Vertical farming has already started in South Korea. Another project, based in Suwon, is growing food in a three-story building and may eventually expand into a skyscraper. But the outdoor vertical farm is just a concept for now. Lee and Park are confident this is the way of the future, and that demand for clean, sustainable buildings that grow fresh food is only going to increase:

We believe there will be more attention and discussions of vertical farms as the 2015 Milan Expo approaches, and we hope the Urban Skyfarm can become part of the discussion as a prototype proposal. Vertical farming really is not only a great solution to future food shortage problems but a great strategy to address many environmental problems resulting from urbanization.

And with the problems of urban growth and diminished farmland occurring all over the developed world – but especially in nations like China, Indonesia, the Philippines, and India (which are likely to be the hardest hit by Climate Change) – innovative designs that combine sustainability and urban farming are likely to become all the rage all over the world.

Climate Crisis: China’s Pollution-Eating Skyscrapers

phoenix-towers-worlds-tallest-wuhan-china-designboom-01 Though it is already home to the world’s largest building – in the form of the New Century Global Center in Chendu – China is seeking to create the world’s tallest structure as well. Designed by UK-based Chetwoods Architects and known as the Phoenix Towers, this tower concept is slated to be built in Wuhan, Central China. But equally impressive is the fact that this building will be suck pollution out of the air and water and will host more than the usual building features.

The larger of the two towers reaches a total of 1000 meters (3,280 ft) in height – beating the Burj Khalifa by 170 meters (558 ft) – and sports an ambitious list of sustainable technology. The towers cover 7 hectares (17 acres) of ground on a 47-hectare (116-acre) plot that sits upon an island in a lake. In an attempt to make the design of the towers more relevant to Chinese culture, Chetwoods drew upon the Fenghuang (or Chinese Phoenix) mythological bird and designated the larger tower Feng (male), and the smaller tower Huang (female).

phoenix_towers_chetwoods-2The designers hope the building will serve as a catalyst for more sustainable design in the industrial city. Laurie Chetwood, chairman of U.K.-based Chetwoods, the architects on the project explained how the building’s water-cleaning features work:

The water goes up through a series of filters. We don’t use power to pull the water up, we’re using passive energy. As it goes through the filters and back, we’re also putting air back into the lake to make it healthier… Wuhan is an unusual city, dotted with huge lakes. Protecting the lakes could lead to other projects that protect them even more.

The towers also have pollution-absorbing coatings to help clean the air, vertical gardens that filter more pollution, and a chimney in the middle of the larger tower naturally pulls air across the lake for better ventilation. For the sake of generating energy, the building relies on a combination of wind turbines, lightweight solar cladding, and hydrogen fuel cells running on the buildings’ waste, giving it energy independence and even having enough left over for the local community.

phoenix_towers_chetwoods-4Inspired by the Chinese symbols of the phoenix, and the concept of yin and yang, one tower feeds the other with renewable power in a symbiotic relationship. Spheres hanging between the two towers will also hold restaurants with views of the lake. Pending approval by the city’s mayor, construction may begin by the end of the year and could be completed by 2017 or 2018, a pace that the architects say would be unlikely in other countries.

According to Chetwood, construction in China obeys a different set of rules and parameters than his native Britain:

The most amazing thing for me is that in the U.K. we strive as designers to get things built, and there’s a lot of red tape, but the Chinese seem to have a different view of things. I think they’re incredibly optimistic. If you have an idea and you think, ‘Oh, is this going to be too exciting’, they’ll actually want it more exciting. It’s more ambitious. They’re quite keen to push the boundaries. For a designer, that’s fantastic. It’s a thrill.

Whereas the sheer size of the buildings is reflective of China’s aim to assert its national authority on the world stage, it’s focus on pollution-eating and green energy is reflective of the desire to create living spaces in a sustainable way. And it is one of many building concepts being considered by Chinese authorities that seeks to address pollution by achieve energy independence, while at the same time being part of the solution by incorporating pollution-eating features.

shanghai_towerFor instance, there’s China’s Shanghai Tower, which finished construction in August of last year. This building is currently the tallest tower in China, is one-third green space and a transparent second skin that surrounds the city in a protective air envelope that controls its internal temperature. In addition, vertical-axis wind turbines located near the top of the tower and geothermal vents located at the bottom will generate 350,000 kWh of supplementary electricity per year.

And then there’s Sky City, a building under construction (though currently on hold) in Changsha, Hunan province. Designed by Broad Sustainable Building, this 666m meter (2,185 ft) skyscraper incorporates numerous sustainable building features. These include modular design, recycled building materials, non-toxic building materials, insulated walls and quadruple glazing. Beyond China, there is also the Pertamina Energy Tower in Jakarta, which relies on geothermal, solar, and wind turbines to act as the very picture of energy independence.

Together, these concepts (and many others currently under consideration) represent the future of urban planning and architecture. In addition to being assembled with recycled material, fabricated using less wasteful methods (like 3-D printing), and seeing to their own energy needs in a clean and sustainable way, they will also incorporate carbon capture, air and water cleaning technology that will make urban environments healthier places to live.

Climate Crisis: Terraforming the Desert

green_machineNow that I’m back from my European adventure, I finally have the time to catch up on some news stories that were breaking earlier in the month. And between posting about said adventure, I thought I might read up and post up on them, since they are all quite interesting to behold. Take, for example, this revolutionary idea that calls for the creation of a rolling city that has one purpose in mind: to replant the deserts of the world.

Desertification is currently one of the greatest threats facing humanity. Every year, more than 75,000 square kilometers (46,000 square miles) of arable land turns to desert. As deserts spread – a process that is accelerating thanks to climate change and practices like clear-cutting – the UN estimates that more than 1 billion people will be directly affected. Many of them, living in places like Northern Africa and rural China, are already struggling with poverty, so the loss of farmland would be especially hard to handle.

green_machine_balloonsAs a result, scientists are looking to come up with creative solutions to the problem. One such concept is the Green Machine – a floating, self-powered platform that would act as a mobile oasis. Rolling on treads originally designed to move NASA rockets. Designed by Malka Architecture and Yachar Bouhaya Architecture for the Venice Biennial, this mobile city would roam the drylands and plant seeds in an effort to hold back the desert.

The huge platform would be mounted on sixteen caterpillar treads originally made to move NASA rockets, while giant floating balloons that hover from it capture water condensation. As the first treads roll over the soil, the machine uses a little water from the balloons to soften the ground while the last set of treads injects seeds, some fertilizer, and more water. The entire platform would run on renewable power, using a combination of solar towers, wind turbines, and a generator that uses temperature differences in the desert to creates electricity.

green_machine_cityThe machine could theoretically capture enough energy that it can self-support an entire small city onboard, complete with housing, schools, businesses, parks, and more farmland to grow produce for the local area. This city would house and support the many researchers, agronomers, workers and their families that would be needed to oversee the efforts. Similar to what takes place in oil drilling, these individuals could be flown in for periods of work that could last up to sixth weeks at a time before rotating out.

The designers were inspired by Allan Savory, who has proposed a much lower-tech version of the same process that relied on cattle to naturally till and fertilize the soil. For the architects, building on this idea seemed like a natural extension of their work. If the machine went into action at desert borders, the designers say it could help formerly barren soil produce 20 million tons of crops each year, and could even help slow climate change by capturing carbon in soil.

green_machine_terraOver time, biodiversity could also gradually return to the area. The architects are currently working on developing the project on the Moroccan side of the Sahara Desert. As Stephane Malka, founder of Malka Architecture, put it, it’s all about using the neglected parts of the world to plan for humanity’s future:

For a long time, my studio has developed work around neglected spaces of the city. Deserts are the biggest neglected space on Earth, as they represent more than 40% of the terrestrial surface. Building the Green Machine units would be able to re-green half of the desert borders and the meadows of the world, while feeding all of humanity

As to the sheer size of their massive, treaded city, the designers stressed that it was merely an extension of the challenge it is seeking to address. Apparently, if you want to halt a worldwide problem, you need a big-ass, honking machine!
