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.
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.
“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.
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.
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.
“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).”
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.”
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.
Cyclone Idai Aftermath: No Maize, No Money, No Future
The deadliest African cyclone, to date, tore through Zimbabwe, Malawi and Mozambique in March, leaving a trail of death and destruction. The worst is yet to come for survivors.
The deadliest cyclone to ever hit Africa, Idai, overnight, ripped through Mozambique and then tore into Zimbabwe and Malawi, leaving a long trail of destruction in its wake.
Trees were uprooted, so were people, in the millions.
Roads were washed away, houses destroyed and bridges torn from their edifices. Worst of all, the raging muddy waters killed at least 847 people, affected about two million and destroyed several hundreds of thousands of crops. The devastation caused by the cyclone is almost unimaginable as, in these three countries, bodies could be seen floating in water where there used to be villages.
“This was unimaginable. I am in the military but I have never seen such. People are desperate for help and have lost everything,” says Brigadier General Joe Muzvidziwa, who is helping survivors in Zimbabwe.
For those who did survive, the worst is yet to come. Many of them will mourn the deaths of their loved ones on empty pockets and growling stomachs.
The drive to Zimbabwe’s hardest hit district, Chimanimani, is long and painful. A mere six days after the furious waters swept away most parts of the villages in the area, the ground is dry but the pain and destruction still palpable.
We struggle to drive into the villages as trees and debris still block the roads and bridges have been decimated.
We continue our journey on foot and meet many with no place to call home. One of them is Tsitsi Mungana.
As we meet, she is trying to climb over a tree blocking the road, to make her way to aid agencies for her first decent meal since Cyclone Idai. She is walking barefoot and is wearing the only dress and doek (headwrap) she now owns. She mutters a few words to herself as tears stream down her cheeks.
“It’s been the worst time of my life. I don’t know how I am going to move on from this. I don’t have anything else left. My husband was swept away by the floods and was found about 10km away… We spent hours looking for my grandson. The rocks which fell off the mountain due to the heavy rains and wind covered his body and it took many people to find him. All our belongings and livestock are also gone,” says Mungana as she begins to weep uncontrollably.
She is one of hundreds of families who have lost loved ones, and thousands who are most likely going to starve this year.
According to Wandile Sihlobo, Chief Economist of the Agricultural Business Chamber of South Africa (Agbiz), Mozambique, Zimbabwe and Malawi will collectively have to import over a million tons of maize this year to feed its people.
He says Zimbabwe’s maize imports could reach 900,000 tons in order to meet the annual needs of roughly two million tons a year.
“Meanwhile, Mozambique will most likely double the typical maize import volume of about 100,000 tons a year,” he says.
It’s going to be hard to find suppliers of maize because the key suppliers, South Africa and Zambia, are expecting low harvests this year.
“If we assume that South Africa’s expected production of 10.6 million tons materializes, then the country could have about 1.1 million tons of maize for export markets. A large share of this will, most likely, be destined to the BNLS countries (Botswana, Namibia, Lesotho, and Eswatini), thus leaving a small volume for Zimbabwe and Mozambique,” Sihlobo says.
There is also very little to be expected from Zambia as the International Grains Council forecasts the country’s 2018/19 maize harvest at 2.4 million tons, down by 33% year-on-year. This will be enough only for domestic consumption.
Cyclone Idai also affected trade.
In its wake, according to the UN Economic Commission for Africa Executive Secretary, Vera Songwe, the cyclone cost Africa infrastructure worth more than a billion dollars.
Port of Beira, the main corridor for Zimbabwe, Zambia, Malawi and Eastern DRC, closed its doors.
“We closed the port two days before the cyclone hit to allow us time to prepare for it by reorganizing and removing all potential hazards. There was a lot of damage to the port. It took another two days to clean up and, at least, make the port accessible. The damage was several millions of dollars. We are currently in talks with insurance to know how much exactly. It will take time and money to fix everything up. We are currently improvising just to make sure business goes on,” says Jan de Vries, Managing Director of Port of Beira.
Before this disaster, Beira port controlled 60% of the country’s imports and 40% of its exports.
“We handle about 300,000 containers per year and about three million tons of general cargo per year and a lot of fuel but we had to put services on hold… On the first day, it was tough to go around. Nearly all the roads were blocked, to some extent, with trees, electricity cables and many things. There was a lot of destruction. A lot of roofs damaged, buildings completely collapsed. This place looked like a warzone,” de Vries says.
He says at the port, roofs, doors and warehouses were destroyed but they are lucky because it is currently low season.
“Electricity supply had been cut off but we are very impressed by the government because power is being restored. Technicians from all over the country are working hard. Major industries have been reconnected and a few residential areas are now being connected. Rail and road infrastructure is also being fixed. Although we have to struggle a bit, we have opened the port and business continues,” he says.
The president of the Confederation of Zimbabwe Industries (CZI) Sifelani Jabangwe says Beira is one of the major ports for the SADC (Southern African Development Community) region and its closure, no matter how short-lived, affected trade.
“Zimbabwe imports fuel and wheat through the Port of Beira. The closure caused a strain on the supply of these two commodities. We had trucks that were stuck in Beira for a number of days. The bigger impact is also on businesses located on the eastern sides of the country, like timber estates, fruit and tea producers, and even the diamond company, in that area, is now revising its targeted output because of the flooding,” Jabangwe says.
Henry Nemaire, the Chairman of the CZI Trade Development and Investments Promotion Committee based in Mutare, says most businesses have been severely affected and are looking for funding to rebuild.
“Some businesses are in areas that can’t be accessed with 30-ton trucks which they used to move their goods like timber… Power lines are cut off and there are issues around water supply systems which have been damaged. Smaller businesses were the most affected. Most of them are now trying to apply for loans to get new trucks and rebuild so they can get back on track,” Nemaire says.
Jabangwe agrees with Nemaire. He says it will be a long and harsh road to recovery.
“We are still waiting for reports from various companies affected by the cyclone which should start coming in soon so we can understand the actual loss that has occurred… there are already teams working with government to import the required maize to feed the country. We need additional support to make sure that people are catered for. We would need to feed people in that area for at least 12 months, which means a full-fledged program has to be put in place,” he says.
Cherukai Mukamba, a local smallholder farmer, says he relied on farming to make money. “I would sell maize and chicken, and sometimes cows, to make money to be able to take care of my children. A week before the cyclone, I had hired people who were going to help me with harvesting when the time came,” he says.
Like many in this area, Mukamba spent the night fearing for his life and that of his family.
“I was asleep and was woken up by very loud winds that I have never heard before. I went outside to look and right in front of me, was a bus rolling down the mountain. I could hear people scream and it crushed them before my eyes. I tried to go help but it pouring and I could see rocks fall off the mountain right into the fields and I had to go back in the house and say a prayer.”
The next day, Mukamba says he woke up to the biggest horror.
“Everything was destroyed; all my crops, livestock and part of my house. I went to check on the bus but didn’t find anyone inside. I heard that there had been three people in the bus and their bodies were found over 100km away. I couldn’t believe it. It is the worst thing to ever happen to us,” he says.
Mukamba’s story is one of thousands of stories in Zimbabwe, Malawi and Mozambique.
These countries have weathered many storms over the years like Cyclone Leon–Eline and poverty, but this massive natural disaster will go down in history books as the worst and southern Africa will bear its scars for generations to come.
Uganda Sees 11% Growth In Sugar Output This Year
Uganda expects sugar output to rise 11% this year as three mills under construction in the country’s northern and eastern regions come online, officials say.
“Production is currently at 450,000 metric tons. When three new factories that are under construction and development start producing, we will go up to a half a million metric tons,” Uganda’s Trade and Industry Minister Amelia Kyambadde says in an interview with FORBES AFRICA.
The East African country is only able to consume 360,000 tons per year, leaving a surplus for export in a region that’s grappling with deficits. Uganda exports sugar to the DRC, Kenya, Rwanda, South Sudan and Tanzania.
Underpinning the country’s sugar sector are millers, including Kakira Sugar Works, the largest producer. Sugar Corporation of Uganda Limited – Lugazi and Kinyara Sugar Works are the other largest players.
While this growth in output is imperative, the government is keen to see diversification in production to include industrial sugar as the country seeks to save its foreign exchange, Kyambadde says.
“I see a bright future,” she adds, “but producers also need to diversify and produce the finer sugar. All of them are producing the bigger crystals but finer sugar for production is what we would like them to start producing.
“At the moment, we are importing that finer sugar.
“So that has been our concern with them, that why don’t you diversify and start producing the sugar that’s ready for production,” she says.
But these efforts have largely been stalled by Uganda’s high power tariffs, according to Kyambadde.
“They (millers) say from this level, the ordinary sugar, they have to have another line that would make it finer. That means the consumption of power definitely is higher,” she says.
“So that is one of the challenges; that the costs of production are so high,” she said, adding that new power plants will reduce costs to an ideal five US cents/KW.
Uganda is also looking to establish new laws to govern the sugar sector but disagreements over exclusivity clauses relating to purchase of cane from farmers abound.
In March, President Yoweri Museveni declined to assent to the Sugar Act of 2016 that was passed by Parliament in November last year. His spokesman, Don Wanyama, says the president is concerned about the proximity of millers.
“It’s going to antagonize the old sugar players,” Wanyama says. “It’s (the act) not going to be assented to,” he says.
“We hope this issue will be corrected now that the bill is being sent back to parliament,” says Jim Kabeho, the Chairman of Uganda Sugar Manufacturers Association, the largest industry lobby.
“Farming constitutes 60 percent of our costs; yet someone without a single tractor and using cheap old machinery just wants to come and buy from your farmers,” he said in a phone interview.
Kabeho, also a director at Kakira and a board member at regional business lobby, the East Africa Business Council, warns that Uganda has lessons to learn from Kenya which allowed “market distortions” in the name of allowing competition only to end up with less production and having to rely on imports.
Yet for Ibrahim Baliitamuto, a cane grower in the eastern district of Mayuge, all that matters is price stability.
“It’s very easy to make a fortune from sugarcane if the prices offered by factories are not changed very often,” Baliitamuto says.
“You can’t tell me about growing maize (corn) when I have a choice of sugarcane.”
Kyambadde says in returning the law to parliament, the president was being mindful of the big players.
“He thinks that the output of the small players is negligible, but we are still discussing that,” she says.
Why Do Zebras Have Stripes? They Make Bad Landing Strips For Flies
Scientists are providing new evidence to answer the longstanding question about why zebras have stripes. It appears stripes make terrible landing strips, bamboozling the fierce blood-sucking flies that try to feast on zebras and carry deadly diseases.
Researchers on Wednesday described experiments demonstrating that horse flies have a difficult time landing on zebras while easily landing on uniformly colored horses. In one experiment, the researchers put cloth coats bearing striped patterns on horses and observed that fewer flies landed on them than when the same horses wore single-color coats.
“We showed that horse flies approach zebras and uniformly colored horses at similar rates but that they fail to land on zebras – or striped horse coats – because they fail to decelerate properly, and so fly past them or literally bump into them and bounce off,” said behavioral ecologist Tim Caro of the University of California-Davis, lead author of the research published in the journal PLOS ONE.
Close cousins to horses and donkeys, the world’s three zebra species, known for their black-and-white striped bodies, roam Africa’s savannas eating a variety of grasses. Their stripe patterns vary among individuals, with no two alike.
There had been four main hypotheses about the advantages zebras accrued by evolving stripes: camouflage to avoid large predators; a social function like individual recognition; thermoregulation, with stripes setting up convection currents along the animal’s back; and thwarting biting fly attacks.
“Only the last stands up to scrutiny,” Caro said. “Most biologists involved with research on mammal coloration accept that this is the reason that zebras have stripes.”
African horse flies carry diseases such as trypanosomiasis and African horse sickness that cause wasting and can be fatal.
Breeding high performance bugs for animal feed
The researchers videoed horse flies as they tried to prey on captive zebras and domestic horses at a livery in North Somerset, England. Stripes did not deter flies from a distance, as they circled horses and zebras at similar rates. But the flies managed to land on zebras less than a quarter as often.
University of Bristol biologist and study co-author Martin How said stripes may dazzle flies somehow once the insects venture close enough to see them with their low-resolution eyes.
“In addition to stripes that prevent controlled landings by horse flies, zebras are constantly swishing their tail and may run off if horse flies do land successfully, so they are also using behavioral means to prevent flies probing for blood,” Caro said. -Reuters
