Africa's Organic Farmers Struggle to Get Certified
Organic farmers in Africa face an arduous journey getting cropland certified, limiting exports and frustrating farmers who say ecological practices could increase food security while protecting the land.
Just 2 percent of Africa's farmland is considered organic — seven times less than the global average, according to data from the Research Institute of Organic Agriculture (FiBL) — in a continent where natural agricultural and subsistence farming are widely practiced. Farmers who avoid synthetic fertilizers and pesticides but are unable to get organic certificates say their plans to export abroad are stymied by high costs, corruption and little government support.
And then there's the bureaucracy.
"The ceiling is so high for smallholder farmers to be part of the international market," said Ara Nashera, a farmer near Mount Kilimanjaro in Kenya who wants to get organic certification to sell chilies abroad. "When I looked last year at how many agencies I have to go through to start exporting, there were 53. You don't even know where to start."
Alfred Koleta, an organic farmer in the same region who is relying on sales of cassava to pay his children's school fees, said the complexity of the years-long process puts farmers off getting certified. "Unless you get someone to introduce you... it's quite challenging, it's quite tedious, because this process requires multiple agencies."
More than half of Africans are smallholder farmers and agriculture is a central pillar of economies across the continent. With Africa's population set to double by 2050 and its crops increasingly menaced by extreme weather, soil erosion and desertification, farming choices today will play a key role in the continent's food security.
"Conventional methods have been eating up arable land and making it barren," said Nashera. "If we waste land now, then food will be very expensive in the future and we'll have more people fighting for very little resources."
But scientists and farmers alike are divided on the benefits of organic farming.
Conventional farming uses artificial fertilizers and pesticides, some of which kill wildlife and may damage human health, particularly in countries where they are poorly regulated or overused.
A landmark report on biodiversity published by UN-backed scientists last year found that converting land for intensive agriculture is one of the biggest drivers of wildlife loss and degradation of nature — and that this, in turn, endangers the global food system through the less of healthy soil, clean waterways and insects that pollinate plants.
At the same time, organic farms typically require more land to achieve the same yield as conventional farms do, a review paper published in the journal Science Advances in 2017 found, meaning an expansion of organic could accelerate climate change and worsen hunger. Without an increase in modern farming too, this could prove deadly in sub-Saharan Africa. About 20 percent of sub-Saharan Africans are undernourished, data from the UN's Food and Agriculture Organization shows, and East Africa is in the midst of an "unprecedented" threat to food security from a locust plague that is set to worsen in coming months.
But for smallholder farmers with limited equipment and low yields, a switch to organic methods could even be a boon to harvests and reduce post-harvest losses. "The [technical] capacity is so low that if you go organic but have some good practices... you could even increase productivity," said Malick Kane, author of a report on financing organic farming in Africa and project coordinator at UNCTAD, the UN's trade think tank. "You wouldn't necessarily face a food security challenge."
Access to Finance
The area of organic farmland in Africa has doubled in the last decade to 2.1 million hectares, FiBL data shows, with the biggest organic centers in North and East Africa and the crops they grow enjoyed the world over. In Kenya, nuts and coconuts dominate organic output. In Tunisia it is olives. Ethiopia and Tanzania are big coffee-growers, while in Uganda, home to the most organic producers in Africa, the crop of choice is cacao.
Despite some successes, farmers such as Nashera and Koleta, in Kenya, are caught in a bind between domestic markets not willing to pay a premium for organic food and wealthier regions to which they cannot export without expensive certification. A survey of African farmers by UNCTAD in 2016 found that a quarter of stakeholders thought access to finance had gotten more restrictive in the last five years. Only 13 percent said it had become more efficient.
But the industry is held back by more than just money, said Okisegere Ojepat, CEO of trade association Fresh Produce Kenya. A lack of crop-specific research and equipment, including understanding of weather patterns and pest control, is keeping farmers from innovating. Pushing for more organic farming without building technical capacity would not be sustainable in the long run, said Ojepat. "It is a double-edged sword."
Organic farmers looking to reach markets abroad are trying short-term fixes. To reduce the cost of certification — which requires paying auditors from Europe and North America to fly in and inspect farms — organic farmers could apply to be certified together, said Claire Nasike, founder of environmental educational charity the Hummingbird Foundation and an agroecologist at Greenpeace Africa, which has trained a network of farmers who are now applying to be certified as a group.
"The farmers are able to hold each other accountable," said Nasike. "If one person messes it up, the entire group's certification is cancelled."

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.

It is undisputed that vitamin D plays a role everywhere in the body and performs important functions. A severe vitamin D deficiency, which can occur at a level of 12 nanograms per milliliter of blood or less, leads to severe and painful bone deformations known as rickets in infants and young children and osteomalacia in adults. Unfortunately, this is where the scientific consensus ends.
Where Does the Deficiency Begin?<p>Nobody knows exactly how much vitamin D a person actually needs. The question of when a deficiency starts is correspondingly controversial. However, vitamin D is becoming increasingly popular.Not only is the pseudo-scientific literature on the "sun vitamin" experiencing an upswing, but the number of published studies has also increased enormously in recent years. For example, in 2019 <a href="https://academic.oup.com/edrv/article/40/4/1109/5126915" target="_blank">a study found that</a> Vitamin D is responsible for keeping the skeleton functional and is associated with cardiovascular diseases, type 2 diabetes and various types of cancer. <br></p>
An All-Rounder<p>Vitamin D levels in the body rise and fall according to sun exposure. If sufficient UV rays reach the skin, the body is able to produce the vitamin itself. However, the human body only derives an estimated 10 to 20 percent of its daily requirement from food.</p><p>The vitamin D that we synthesize from sunlight or food is not biologically active at first. Before the kidneys can produce the biologically active form of the vitamin, known as calcitriol, and release it into the blood, some metabolic processes must take place beforehand.</p><p>In addition, many organs have receptors to which the precursor of calcitriol binds. Further, this substance is also present in blood.</p><p>From this precursor, the organs then produce calcitriol themselves, which the body then uses for countless other processes in the body. This form of vitamin D thus regulates insulin secretion, inhibits tumor growth, and promotes the formation of red blood cells as well as the survival and activity of macrophages, which are important for the <a href="https://www.mdpi.com/2072-6643/5/7/2502/htm" target="_blank">immune system.</a></p>
Low Vitamin D, Severe COVID-19 Disease?<p>A research study carried out <a href="https://www.sciencedirect.com/science/article/pii/S2352364620300067?via%3Dihub" target="_blank">at the University of Hohenheim</a> has now established a link between vitamin D deficiency, certain previous diseases, and severe cases of COVID-19.</p><p>According to the study, "there is a lot of evidence that several non-communicable diseases (high blood pressure, diabetes, cardiovascular diseases, metabolic syndrome) are associated with low vitamin D plasma levels. These comorbidities, together with the often accompanying vitamin D deficiency, increase the risk of severe COVID-19 events."</p><p>"This statement is completely correct," said Martin Fassnacht, head of endocrinology at the University Hospital of Würzburg. However, he qualifies that it is a pure association, "i.e. a mere observation that these events occur together.</p><p>Dr. Fassnacht is very critical of the hype surrounding vitamin D, but not because he denies the vitamin serves important functions. However, studies on humans have not been able to show that vitamin D has the healing powers many often propagate.</p><p>Fassnacht says, "If you take a closer look, the hopes that the administration of vitamin D has a healing effect have not been confirmed so far."</p>
Association Versus Intervention Studies<p>Many studies on the vitamin are association or observational studies. "By definition, these studies cannot prove the causal relationship, but only point to mere correlations," said Fassnacht. The physician tries to illustrate this with an example:</p><p>"Imagine two groups of 80-year-olds. One group is spry, active and does sports. If you compare them with another group living in nursing homes, the difference in vitamin D levels will be dramatic. Life expectancy would also be extremely different."</p><p>But to try to explain the difference in fitness by vitamin D status alone is far too simplistic. "Vitamin D levels are a good measure of how sick someone is. But not more," says Fassnacht. </p><p>According to Fassnacht, none of the intervention studies carried out to date -- that specifically examined the effect of vitamin D on various diseases -- has been able to confirm the previous association and laboratory studies or the presumed positive effect of vitamin D.</p>
Further Research Is Needed<p>"If a coronavirus infection is suspected, it is therefore absolutely necessary to check the vitamin D status and quickly correct any possible deficit," said the recommendation of the paper published by the University of Hohenheim.</p><p>"Studies are underway to see whether vitamin D helps in COVID-19 infection, but I personally do not believe that this is really the case," says endocrinologist Fassnacht. Nevertheless, he says it is of course useful to carry out these studies.<br></p><p>"I don't want to rule out that there are actually subgroups of people who benefit from an additional vitamin D dose," he says. After all, this has been proven to be the case with a severe deficit.</p><p>In view of the study situation, Fassnacht does not think much of preventive, nationwide vitamin D substitutes. "My belief that the vitamin helps somewhere is very low. But, of course, I can be wrong."</p>
