    A communication gulf exists in our modern world between scientists and non-scientists. Yet we can all use a TV without knowing how it works, or take antibiotics for pneumonia without a biology qualification, just as we can pick up WiFi without understanding internet protocols.

    However, when a gap in general scientific knowledge begins to be exploited to deliver a political victory or precedent that will benefit some, but hurt many more of us, it can start to matter a lot that we and our policy makers get to grips with the science involved.

    And so it is with the current debate on pest control.

    For, there have been anti-technology movements and scientific rifts throughout history, but with our climate warming, and pressures of population, food, water and other resources all growing, it is now vital we distinguish between the ‘Earth-is-Flat’ movements and the ‘Earth-is-Round’ movements of our modern world.

    And, in this, none of fervency, celebrity, or level of noise are indicators of the rights and wrongs. Indeed, it would be a subject for a keen historian to examine such science clamours and see if the views that were the less fervent, the less popularised and the more practical, academic and drier always turned out to be the correct ones, or whether both polar opposites were normally equally loud and passion-driven.

    Either way, my own science community has done a poor job, as scientists, in explaining the safety checks and essential nature of pest control products once faced with posters of vegetables that say ‘choose your poison’. It doesn’t matter that we put these products through nine years of international testing to establish how they can be used without poisoning people, or that they are based on molecules that break down in days, so they simply do not exist some days after they are deployed to control one pest or another.

    Faced with a celebrity-filled poster, the chemistry of molecular breakdown isn’t a route to hearts looking for a cause. However, it just so happens that it is a scientific fact that makes a massive difference to our health and food security.

    Individual examples of that difference abound, and we have managed to speak about locusts, which actually cannot be killed by banging pans, and actually do eat entire crops and breed vigorously. We have also spoken of Fall Army Worm, which has swept through our maize crops triggering shortages. But the pests that face our farmers, and which are routinely resolved in Europe and North America, Australia and much of Asia with pest control products, are sometimes as simple as the dipping of cattle to prevent ticks and the deadly diseases they give to animals and humans alike.

    From Crimean-Congo heamorrhagic fever, Lyme disease, Relapsing Fever (borreliosis), Spotted Fever, Q Fever and all the other Rickettsial diseases, Tick-borne encephalitis, Tularaemia, and others, our rural populations are already beginning to suffer more from the growth in ticks on the decline in tick control, and these are ugly, high-temperature, rapid deaths, for the most part.

    Indeed, the global One Health movement has been driving awareness that healthy people require healthy animals and environments: you don’t just allow ticks and locust and Fall Army Worm to flourish uncontrolled and expect to enjoy a healthy population. Such pests and parasites carry dozens of vector-borne diseases that kill some three-quarters of a million people a year.

    This disease bomb, which some campaigners are seeking to call healthy compared with using pest control made from molecules that break down, is compounded by more than 600 types of weeds that are getting into crops and introducing pyrrolizidine alkaloids – found in herbal teas, honey, herbs and spices, cereals and other foods, according to the World Health Organisation (WHO) - which damage human DNA and actually do cause cancer.

    For we scientists, familiar with the poisonous nature of these natural toxins - actually called ‘toxins’ by the WHO, which knows at least one or two things about what is toxic and what isn’t - the current manipulation of scientific information with false claims, celebrity posters and viral videos is hard to know how to counter. How do all of us in agriculture counter this onslaught from those who are making a living and their political fund raising through trying to get Kenya to deliver a world first that they can claim as their victory?

    For these campaigners want nearly all pest control banned in Kenya, where all of those products are used across the rest of world, in Tanzania, in Uganda, as well as in the USA and Australia, and by our food trading partners.

    Articles in the Wall Street Journal have attacked this campaign in Kenya as green colonialism, funded, as it is, almost entirely from European political funds. 

    But whoever is funding the big and glamourous noise underway, the children dying of encephalitis will be a lot quieter, as will the families who lose their maize to Fall Army Worm. And what their future depends on is not the glamour, but the facts, the tests, the solutions, the costs and benefits, and the hard stuff of serious decision making, away from the studio lights, and driven by hard realities of death by tick. For Kenyan lives matter.

    Bag Gardens

    By Jolene Njambi

    When Maureen Chelagat, from Sotik, Bomet County, decided to venture into vertical farming, she only had ambitions of saving on a few coins that she would spend buying vegetables for her family of three. She had no idea that it would result in a full indoor garden of 15 five litre Jerri cans, and her saving on her daily consumption costs by up to 80 per cent.

    Two months ago, she began her vertical garden by planting onions, tomatoes, garlic, thyme, chilies and passion fruit seeds in five of her leftover five-liter Jerri cans. She bought seeds from the same nearby market where she would buy her vegetables from, cut the plastic cans in half, used soil mixed with chicken manure from the chicken that she rears, and committed to watering her seeds twice a day.

    Since then, she has been able to grow 15 Jerri cans that yield at least five crops each of all the seedlings she planted.

    “Now, even my neighbours request vegetables from me. They also get to save on costs they would have initially incurred from buying these same vegetables from the market.”

    Before chancing on vertical farming, she used to spend around Sh100 daily on buying onions, tomatoes, thyme, garlic and chilies. Now she only uses Sh20 for sukuma wiki and Spinach.

    Realizing that her garden is gaining popularity, she is now confident that she should be able to sell her vegetables for profit in the near future.

    In the mean-time, she is transitioning from using Jerri cans to sacks as they leave more room to produce more yields. She is now focusing on growing more of sukuma wiki and spinach as she has noted there is an increasing demand for them from her neighbours.

    “As they request for vegetables, many ask if I have sukuma wiki too. I have noticed that it is more in demand than the spices I have been growing.”

    This is also in proper alignment with her future business ambitions. She hopes that by continuing to expand her vertical garden she will be able to better feed her family.

    Tight times and rising food prices can leave urban dwellers stranded, but one resident in Kikuyu is proving that barely more than a couple of metres of space is enough to keep an urban family fed and even produce some commercial returns, using vertical farming.

    With the current population of Nairobi at 4.3m and expected to balloon to 12.1m by 2030, the risk of urban food shortages has only grown, as have prices too. For instance, the price of a kilo of Kale rose by 63.2 per cent in 2017 from Sh38 to Sh60, according to KNBS.

    But Paul Mwai is an example of an urban dweller who has worked to give his family food security by venturing into vertical gardening three years ago, from his home in Karai, Kikuyu.

    “What really pushed me to look at this venture was the high price of common food commodities such as coriander, spinach, kales, broccoli and herbs. For example in 2018, the price of a single bunch of coriander was Sh5, but in 2020 the same bunch is sold at Sh10 and this is not the only commodity that has increased in price,” said Paul.

    A study by Mazingira Institute showed that 29 per cent of urban dwellers practice urban crop farming and 17 per cent practice animal rearing in Nairobi, in a percentage that could even curtail rising urban agricultural prices if home farming rises further.

    Currently, however, about 60 per cent of individuals in Nairobi depend on purchasing food commodities from supermarkets and food markets.

    In his venture, Paul uses vertical pyramids of about 8 inches per layer to grow a variety of vegetables, such as kales, spinach, broccoli, coriander, beetroot and herbs.

    “There are different ways of vertical gardening, with the most common one being sack gardening, which I first started with. Unfortunately, this did not prove viable, since after every six months I had to change the sack, but with using polymer plastic, I have not changed my garden material for the past three years,” he said.

    Aside from the fast rotting period, another disadvantage of sacks is that they tend to be bulky and may require more space to achieve a variety of crops. But with the plastic layers, Paul is able to grow a large variety in just five vertical pyramids.

    “This method has assured me of a constant supply of vegetables throughout the year as a single pyramid can hold 80 to 100 plants. On each pyramid I have mixed my vegetables as this helps with limiting pest invasions of my vegetables,” he said.

    The process of mixing soil for a vertical pyramid is similar to mixing soil for sack gardening, the components may vary if one is focusing on organic farming or traditional farming.

    Currently, Paul is looking for a market for vegetables that he is growing this year as he has decided to commercialize his farming venture.
