In Johannesburg, city-dwellers like Linah Moeketsi have taken the future of sustainable farming into their own hands. Where land is becoming scarce, they look to the skies. 



<hr class="wp-block-separator"/>



Doornfontein is one of Johannesburg’s older inner-city
suburbs with decaying buildings and dingy alleys that wear a dour, monochrome
look. 



Daily commuters and street surfers jostle with delivery vans and mountains of metal scrap but the grey of the concrete city makes it hard to believe that there could be a patch of green in a most unlikely location.

Above the humdrum of life here is a rooftop hydroponics farm
looking down on the city, but upwards to a new route to restoration and urban
preservation. 



Atop the eight-floor Stanop building – offering a
breath-taking view of the city and the landmark Ponte Towers in the distance –
one woman has made it her mission to turn a grimy grey terrace into a green
lung on the city’s skyline.



“City life is taking on a totally new direction… even people who think they couldn’t one day farm, find themselves on rooftops,” Linah Moeketsi tells FORBES AFRICA.

Moeketsi grows herbs, used to treat non-communicable diseases (NCDs), in a 250m x 500m greenhouse on the building’s terrace. But her rooftop farm is sans any soil – it uses a hydroponics system.



“I think because we are in the city and we would like to produce for people in the city, hydroponic farming is one of the answers because you can actually harvest more than twice the produce, and the growth rate is quicker and there is produce that you can have throughout the year that people demand because it is in a controlled environment,” she says.



On a windy Wednesday morning in October, we meet Moeketsi at
her aerial green facility, a couple of days before she is to send some of her
plant produce to the market.



She talks about her journey as an offbeat farmer. It all started when her father fell ill in 2013, when doctors failed to correctly diagnose his disease.



“They couldn’t see that he was diabetic. He didn’t show the signs of diabetes, but he had this foot ulcer that just wouldn’t go away,” she says.



<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">&#8220;The future of city farming is great simply because we have more and more young people getting into this space. Even though it&#8217;s farming, they are looking at it from a very different angle. </blockquote>



Moeketsi decided to do her own research, so she read up
books on African medicinal plants and used some herbs that belonged to her late
mother, who had been a traditional healer.



“It took me a good eight months to help my dad and I
actually saved him from having an amputation.”



The news of Moeketsi curing her dad’s diabetes using herbs
spread. Sadly, her father died in 2016, at the age of 87. But she is proud to
have helped prolong his life.



“So he passed away in his sleep, not sick, nothing, he was just old. But he was always grateful; he was like, ‘even when I die, I’m going to die with both my limbs’, so we would make a joke about it.”

After her father’s demise, Moeketsi rented some land and
turned her knowledge on natural herbs into a fully-fledged farm. However, when
the owner of the land returned, she was forced to vacate.



Land was always going to be a problem in the city. But instead of giving up, Moeketsi looked to the skies.



“Because of this passionate drive for an answer, I found
myself researching what’s happening outside Gauteng and South Africa, and I saw
in Europe, they were farming on rooftops,” she says.



In 2017, her dream became a reality when she secured a deal with the City of Johannesburg as part of an urban farming program, and started the rooftop project a year later.



When we visit her greenhouse, we are welcomed by the sweet
lingering scent of herbs. It’s hot and humid, and two fans whir away to cool
the air.



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="681" height="1024" src="https://www.forbesafrica.com/wp-content/uploads/2020/01/DSC_0043-681x1024.jpg" alt="" class="wp-image-42472" srcset="https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0043-681x1024.jpg 681w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0043-300x451.jpg 300w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0043-600x902.jpg 600w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0043-200x300.jpg 200w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0043-768x1155.jpg 768w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0043-1022x1536.jpg 1022w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0043.jpg 1277w" sizes="(max-width: 681px) 100vw, 681px" /></figure>



Moeketsi walks around the greenhouse wearing dark glasses and a white jacket, with a syringe in hand – she could easily pass off as a medical doctor.



She elaborates on the hydroponics system. There are four pyramids, each attached to their own reservoirs of water. On each pyramid, different plants, ranging from spinach, lettuce, sage, parsley, basil and dill, rest on beds with pipes connecting them to the reservoirs. Moeketsi plucks out one of the pipes and inserts the syringe; water spouts out of the tube and she returns it to the bed.



“Twice a day, you have to check that water is actually going
through the pipes, because that’s how the plants get water and nutrients,” she
explains, as she unblocks a pipe using the syringe. She says it’s one of the
best ways to farm using little water.



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="681" src="https://www.forbesafrica.com/wp-content/uploads/2020/01/DSC_0083-1024x681.jpg" alt="" class="wp-image-42473" srcset="https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0083-1024x681.jpg 1024w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0083-300x200.jpg 300w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0083-600x399.jpg 600w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0083-768x511.jpg 768w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0083-1536x1022.jpg 1536w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0083.jpg 1920w" sizes="(max-width: 1024px) 100vw, 1024px" /></figure>



“When you put in certain plants in the greenhouse, you know
you are guaranteed sustainable farming because you can produce those plants and
harvest them,” she says.



Moeketsi adds that this allows her produce to stay
consistent season after season.



“So, from that point of view, it makes the city more sustainable in terms of food produce that is easily accessible and cost-effective for the consumer because not everyone around here can afford the high prices of food but they can at least afford what we sell, whether it is at R10 ($0.5) or R15 ($1).” 



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="681" src="https://www.forbesafrica.com/wp-content/uploads/2020/01/DSC_0108-1024x681.jpg" alt="" class="wp-image-42475" srcset="https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0108-1024x681.jpg 1024w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0108-300x200.jpg 300w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0108-600x399.jpg 600w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0108-768x511.jpg 768w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0108-1536x1022.jpg 1536w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0108.jpg 1920w" sizes="(max-width: 1024px) 100vw, 1024px" /></figure>



As Moekesti continues to tend to the plants, a farmer she works with walks in and begins filling up the reservoirs. 



Lethabo Madela has known Moekesti for almost six years.



“When you look around Johannesburg, there is no space, so
rooftops have saved us a lot, especially those of us that love farming,” says
Madela. “I’m learning a lot and I think she [Moekesti] changed the whole concept
of farming for me because I used to farm vegetables. I didn’t know culinary
herbs or medicinal herbs.”



Moeketsi speaks of other farmers around the city who have taken to the rooftops to farm plants such as strawberries, lemon balm, spinach and lettuce.

In a suburb called Marshalltown, a 10-minute drive from
Moeketsi’s farm, Kagiso Seleka farms lemon balm also using hydroponics.



He produces sorbet and pesto from his produce which is then
used to make ice cream.



“It [hydroponics] is great for farming sensitive plants in
terms of temperature. Lemon balm does not like frost. But it’s better to grow
even out of season so you can set a higher price,” he tells us.



However, he says hydroponics farming is a luxury not many
farmers can afford.



“It [hydroponics] does have a bit of a higher capital upfront, but you get a higher yield and higher quality, so people are willing to pay more. Hydroponic planting saves about ninety five percent of water soil farming in a water-scarce country,” says Seleka.

“We do have water shortages, and I know people are on the
whole ‘organic trip’ but, is it more important to have an organic plant versus
a water-saving environment?” 



The Program Coordinator for Agriculture at the City of
Johannesburg’s Food Resilience Unit, Lindani Sandile Makhanya, says there
certainly are more rooftop farmers in Johannesburg now than ever before.



Converting idle terraces into avenues of profit is becoming
a norm. There are new rooftop farms being set up every day, offers Makhanya. 



He regularly visits Moeketsi’s farm to check on the progress
and collect produce to sell.



“Urban farming in Johannesburg is rising, mainly because the
idea of producing our own food is very important because most people are moving
to urban areas and therefore it stands to reason that we have to try to produce
as much as possible,” says Makhanya.



“[There is growth] even in animal production, although we are moving away from the bigger numbers, but we are involving the smaller ones; because of the space issue, they are increasing overall.” 



<figure class="wp-block-image size-large"><img loading="lazy" decoding="async" width="1024" height="681" src="https://www.forbesafrica.com/wp-content/uploads/2020/01/DSC_0088-1024x681.jpg" alt="" class="wp-image-42476" srcset="https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0088-1024x681.jpg 1024w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0088-300x200.jpg 300w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0088-600x399.jpg 600w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0088-768x511.jpg 768w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0088-1536x1022.jpg 1536w, https://cms.forbesafrica.com/wp-content/uploads/2020/01/DSC_0088.jpg 1920w" sizes="(max-width: 1024px) 100vw, 1024px" /></figure>



For Moeketsi, her farm has changed her life and given her
hope for a better future. In addition to the teas, tinctures, ointments and
medicinal products she processes from her plants, she plans to include more
by-products such as syrups in the future.



“The future of city farming is great simply because we have
more and more young people getting into this space. Even though it’s farming,
they are looking at it from a very different angle,” she says. “That is why the
city is changing and rooftop farming is going to get bigger and bigger.” 



Clearly, farming in Africa is covering exciting new ground.

Even though Copenhagen is a small city, a mere 88 square kilometers in size, being centrally located is important if you’re on a tight schedule. However, if you do need to use public transport, there is free Wi-Fi on subways, trams and buses. The Lakes, a popular jogging ground, are within walking distance from Nørreport, the main train station.
There is no need to worry if you forgot to pack an umbrella—it rains on average 155 days in a year—need a shirt or want to invest in a well-fitting suit. Copenhagen has the world’s longest pedestrian zone of more than a kilometer, which is lined with shops that sell everything from international brands to Scandinavian fashion. Strøget Street, with its exclusive Illum department store, is the most popular shopping street, while Gammel Mønt, Store Regnegade and Pilestræde have a range of stylish, independent shops.
Take a stroll down Bredgade from here, through one of the oldest parts of Copenhagen until you come to Amalienborg, the home of the Danish royal family, and the impressive Marble Church, built in 1740. Not far from there is the Langelinie promenade and pier, home of the Little Mermaid statue, Copenhagen’s icon, that was donated by Carl Jacobsen, a brewer of Denmark’s famous Carlsberg beer.
<img loading="lazy" decoding="async" class="alignleft size-medium wp-image-1554" src="/wp-content/uploads/2017/04/dreamstime_xl_21845961-300x200.jpg" alt="" width="300" height="200" />
The city’s hour-long canal boat tours will also take you past the mermaid and offer views of the most important landmarks, including the Royal Library, nicknamed the Black Diamond because of its dark glass façade. The library is not only worth a visit because of its modern architecture. Its coffee shop offers free Wi-Fi and one can look out onto the water through the enormous glass façade.
The Radisson Blu Royal Hotel, designed by world-renowned Danish architect Arne Jacobsen, towers over the city center. Its lobby is outfitted with Jacobsen’s original Egg and Swan chairs. To learn more about Jacobsen and his contemporaries, who made Denmark famous for its classic ‘Nordic Cool’ style, visit to the Design Museum and the Danish Design Center. You will get an important insight into the Danes’ mindset: design counts as much as functionality.
The most popular way to get around in Copenhagen is by bicycle. One in three residents use their bike to get to work along the city’s more than 300 kilometers of cycling lanes. Bikes are a great way to explore the city and because Copenhagen is flat, cycling is easy. Arriving at a business meeting on a bike will impress your Danish counterparts. The best part: cycling will cost you nothing, as the municipality provides bicycles free of charge at more than 100 locations throughout the city. They even have a built-in map to show you the way.
If you can’t get yourself to ride a bike, show that you are environmentally conscious by renting an electric car. At $67 a day, it’s cheaper than regular car rentals and parking is free for electric cars throughout the city. It’s all part of Copenhagen’s goal to become the world’s first CO2-neutral capital by 2025.
Surrounded by the North Sea, Denmark is famous for its fish, which makes a seafood restaurant an obvious choice. Fiskebaren, located in the über-trendy meatpacking district Kødbyen, specializes in locally caught fish and shellfish and is as renowned for its minimalist, industrial interior—the aquarium in the center of the space doubles as a fish bar—and its creative dishes. Copenhagen’s restaurants belong to the most expensive in Europe and a 15% service charge is added to the bill.
Noma, voted the world’s top restaurant in 2010 and 2011, is certainly the place to celebrate a business deal. But to get a table at this two Michelin-starred establishment, where Chef René Redzepi only serves produce from Nordic countries, you’ll either have to get very lucky or know far in advance that you will be coming: reservations have to be made as much as a year in advance.
A low-key alternative, ideal for lunch, is Denmark’s national dish, smørrebrød, which are delicious open sandwiches made from dark rye bread and topped with a variety of delicacies, such as Danish meat balls, fried fish, eggs, herring, roast pork or shrimps. Restaurant Schønnemann has been making smørrebrød since 1877; while Ida Davidsen—(with a restaurant of the same name) who is known as the ‘queen of smørrebrød’—has delivered her sandwiches all the way to Hollywood.
The capital’s new culinary hot spot, Torvehallerne, an upscale covered market with more than 80 stalls, gives a good overview of Danish delicacies such as local cheeses, organic sausages, artisanal honey, breads, olive oils, seasonal fruit and vegetables, fresh fish, wines and specialties from small Danish islands. Copenhageners are the biggest consumers of organic produce in the world. Anything fitting the buzzwords: green, sustainable, ethical and social, will sell here.
The city’s best cocktail bar, Ruby Bar, is a great place to relax. Invite your business partners to enjoy a Champagne Figure, a cocktail made from homemade fig puree, bitter chocolate, absinthe and champagne. Another good place to network is the Nørrebro Bryghus, one of Copenhagen’s famous micro-breweries. This beer bar belongs to former Carlsberg master brewer Anders Kissmeyer, who invents a new beer at least once a month. There are dozens of different beers to choose from and most are limited editions.
To show your business partners true commitment to Scandinavia, take them for a drink at the Icebar, Copenhagen’s coolest bar… literally. All its interiors—from the walls to the bar counter, furniture and cocktail glasses—are made from natural snow and ice harvested far above the Arctic Circle. Needless to say, the bar has to be kept at sub-zero temperatures to keep it from melting. But don’t worry, you’ll be given a cozy outfit that will keep you warm.

The construction of one of the world’s most futuristic buildings, in terms of kindness to the environment, happened as an afterthought to the R22.5 billion ($2.6 billion) deal that four years ago saw UK-based multinational cellular operator Vodafone gather a 65% controlling share in South Africa’s Vodacom.
Vodafone’s Innovation Centre, at its headquarters in Midrand, Johannesburg, opened at the beginning of this year. It is a seemingly unremarkable single-story, glass-and-wood structure designed to accommodate only around 12 researchers; but it has been awarded six stars by The Green Building Council of South Africa (GBCSA)— the only such rating achieved in this country and indeed all of Africa. The six stars denote it as a world leader.
<img loading="lazy" decoding="async" class="alignleft size-medium wp-image-1290" src="/wp-content/uploads/2017/04/IMG_7120-300x200.jpg" alt="" width="300" height="200" />
The idea for the building took shape shortly after the mammoth cellular-phone share deal, when the two companies’ technical teams were to be integrated. According to Suraya Hamdulay, Vodacom’s executive head of corporate citizenship, the interdisciplinary task team planning the merger decided it would be nice for the innovators to do their research inside an innovative building.
The whole exercise fitted with Vodafone’s stated intention to, by 2020, reduce its carbon emissions by 50% against its 2006/7 baseline of 1.23 million tons, and to reduce emissions in its emerging markets by 20% in 2015 against a 2010/11 baseline.
It was decided to locate the facility in South Africa because—being both an emerging and a developed economy—it would help consolidate the group’s efforts across the board.
With its six-star rating, the Vodafone facility is at the spearhead of a growing trend in South Africa—as in most of the world’s developed countries and a few developing economies—towards environmentally friendly building practices. The global tendency took a decisive turn in 2002 with the launch of the World Green Building Council, a federation of national councils that was joined by South Africa’s in 2007.
The GBCSA says, on its website, that buildings are estimated to consume 40-50% of the world’s energy through their construction and operation. Green buildings can more than halve the energy use of conventional buildings, with similar reductions in potable water usage, runoff to sewer and solid waste. The council’s purpose is to promote green building, act as a resource center, develop and operate a green-building rating system and improve knowledge and skills through training and education.
The features that had it award the Vodafone Innovation Centre its highest rating are remarkable for their novelty and also for their simplicity. Designed with the help of WSP Environment &amp; Energy South Africa, part of a leading international company, the innovation started with the very choice of a site and its preparation.
The building, reminding one somewhat of an unassuming wildlife lodge, is situated on what used to be a parking lot serving Vodacom’s adjacent headquarters. In the construction, as much use as possible was made of waste and discarded materials. Soil excavated for the foundations and second-hand tiles and reject stock bricks were used in the landscaping of the mainly indigenous garden and its pathways.
The whole purpose was to limit the use of concrete and cement to a minimum. Three layers of compacted soil separated by recycled plastic membranes form the foundations. Gabions resting on the layered foundations support the floor. Outside, air is cooled as it filters through the rock-filled wire-mesh baskets that form the gabions and serve to ventilate the building through vents along the sides.
The double-paned glass walls serve a variety of purposes. They reduce heat from outside and allow hot air trapped between them to escape through vents in the roof. By letting in natural light they limit the use of electric lighting. Bright light is dimmed by the building’s extended eaves and automatic blinds shut out direct sunlight. The see-through walls also create a sense of translucency, especially for those working inside who are able to look out into the garden.
Rain water from the roof goes into tanks from which it is used to flush the toilets and irrigate the garden. Inside the building is a small atrium serving as a wetland through which water from the sinks and basins get purified and re-used to flush the toilets.
The air-conditioning is done by an intricate system of solar tubes on the roof that pipe water into an absorption chiller and cooling coils from which it is passed through pipes in the floor and through cooling grids that are mounted in pot plants for the condensation to wet the plants. A spread of 292 photovoltaic panels, generating 230 kWh a day, drive fans that cool air by blowing it over the cold pipes.
No power-storage batteries are used. Through what is called virtual storage, excess electricity is diverted to Vodacom’s adjacent building to reduce its use of Eskom (the national electricity supplier) power by day. At night, the favor is returned in decidedly unequal measure by passing back such small amount of Eskom power as the Innovation Centre might need.
Even though it is mainly solar power that gets used, everything is designed to limit consumption. LED lighting is linked to motion sensors so that when nobody is in the building the lights will automatically switch off. The researchers work on laptops as they have been found to be the most power efficient.
“We are engineers, we have to have coffee. So we looked around for the most power-efficient coffee machine we could find,” says Etienne Gerber, the center’s program manager.
<h4>There&#8217;s a big new trend in building</h4>
The trend towards greener building is gathering pace in South Africa, as in a good many other countries, despite hard financial times. Since its establishment five years ago, the Green Building Council of South Africa (GBCSA) has already awarded 23 star ratings to buildings around the country. A further 34 buildings are in the pipeline for registration. 
Rosanne Mitchell, the council’s marketing executive, says as consumers become more discerning and environmentally conscious, they will be the drivers of sustainable design and construction as well as greener building occupation. The building industry itself is changing. Green building practices used to be implemented by only a few companies. Now these are practically standard practice. 
Vodafone’s Innovation Centre in Midrand is the only building to have been given six stars. Five more buildings have been awarded five stars for excellence, and seventeen have received four stars, which is for best practice. 
The five five-star buildings are the Standard Bank in Rosebank, Absa Towers West in Johannesburg, the Aurecon Century City Campus in Cape Town, Millennia Park in Stellenbosch and the Sisonke District Offices in Ixopo, KwaZulu-Natal. 
The GBCSA has over 1,000 member companies broadly representative of the private and some public sectors. Apart from developing its rating system, it has put more than 3,000 people through green building courses and accredited 400 green-building practitioners. 
Mitchell says there are strong indications that more and more the construction industry and the corporate world will see green building as an inevitable part of business as usual. As with fire safety standards and disability access, sustainability will soon be taken for granted. 
According to several recent surveys, it will become just the way we build.
