What does the Kilimanjaro, the tallest mountain on African soil, have to do with corals in the ocean? Well, it turns out that there are channels of cool water that developed millions of years ago under the Mt Kilimanjaro, and these end in the Indian ocean off the coast of Mombasa. With the recent warming of the oceans, this cool water meets the ocean right on the coast to create a sort of marine sanctuary for corals, dolphins, and even species taught to be extinct. Enjoy excerpts below from the article at the Guardian!
Scientists have discovered a climate crisis refuge for coral reefs off the coast of Kenya and Tanzania, where species are thriving despite warming events that have killed their neighbours.
The coral sanctuary is a wildlife hotspot, teeming with spinner dolphins and boasting rare species, including prehistoric fish and dugongs. Researchers believe its location in a cool spot in the ocean is helping to protect it and the surrounding marine life from the harmful effects of the climate crisis.
[Tim] McClanahan, the lead scientist for the Wildlife Conservation Society, who lives and works in Mombasa, Kenya, said he had an “epiphany” when he realised why the reef was so rich in wildlife. The coastline has the highest density of dolphins in east Africa, and coelacanths, fish once believed extinct, swim in its deep waters. “I thought ‘why are all the animals here?’ And I realised it was because of Kilimanjaro,” he said.
Have you ever had your car stolen? Have you had to file a police report about it? or just spent days looking everywhere for it, scanning every car in the streets in hope of finding your car? Talk of sleepless nights, and endless talks with the insurance company? Now, imagine having the opportunity to track your car, and immobilize it while the thief is driving it away? Wouldn’t that be great? No more need to deal with busy police, or endless talk with insurance… Hooray to peace of mind!
Well, Zuo Bruno, a Cameroonian entrepreneur has created a car security solution just for you: his mobile application, Zoomed, enables people to track their vehicles and immobilize them if they are stolen, with or without internet. Remember that in many places in Africa, internet is a luxury, or is sketchy, … or like in the case of Zuo, the government had shutdown the internet to his province for over 90 days. His application also enables to track the car’s fuel consumption, which is very helpful if you are the owner of a fleet of vehicles, such as taxis. Enjoy this quick video, and salute the ingenuity of a brother!
We take drawing for granted, and we know that our ancestors, ancient humans thought of drawings as a very good communication tool, as depicted in petroglyphs found in a thousand places on the African continent, in Europe, Asia, and the Americas.
This may be old news to some, but the earliest evidence of a drawing made by humans has been found in the Blombos Cave in the southern Cape province of South Africa. Blombos Cave contains material dating from 100,000—70,000 years ago.
The drawing, which consists of three red lines cross-hatched with six separate lines, was intentionally drawn on a smooth silcrete flake about 73,000 years ago. This predates previous drawing from Africa, Europe and Southeast Asia.
Excavations at the world-famous archeological Blombos Cave site, have yielded many important riches. These include delicately crafted stones and bone implements preceding comparable European artifacts by more than 80,000 years, and at least 8,000 pieces of ochre, used as colour pigment by early humans. This indicates that our ancestors already had an acute sense of colors, and the different properties of these oxidizing colors (ferrous oxide), suggesting a strong understanding of the chemistry behind the colors’ composition.
… the drawings were made with an ochre crayon, with a tip of between 1 and 3 millimetres thick. Further, the abrupt termination of the lines at the edge of the flake also suggested that the pattern originally extended over a larger surface, and may have been more complex in its entirety.
“Before this discovery, Palaeolithic archaeologists have for a long time been convinced that unambiguous symbols first appeared when Homo sapiens entered Europe, about 40,000 years ago, and later replaced local Neanderthals,” says Pr. Christopher Henshilwood from the University of Witswatersrand. “Recent archaeological discoveries in Africa, Europe and Asia, in which members of our team have often participated, support a much earlier emergence for the production and use of symbols.”
The archaeological layer in which the Blombos drawing was found also yielded other indicators of symbolic thinking, such as shell beads covered with ochre, and, more importantly, pieces of ochres engraved with abstract patterns. Some of these engravings closely resemble the one drawn on the silcrete flake.
“This demonstrates that early Homo sapiens in the southern Cape used different techniques to produce similar signs on different media,” says Henshilwood. “This observation supports the hypothesis that these signs were symbolic in nature and represented an inherent aspect of the behaviorally modern world of these African Homo sapiens, the ancestors of all of us today.“

Meet John Amanam, the Nigerian artist/engineer building super-realistic prostheses for Africans in Africa. I really liked his work: this is a self-thought man who used to work in the Nollywood industry, with no real training in prostheses, but a love of sculpture and most importantly of his fellow human being. After noticing family members who had lost limbs, he set out to make realistic-looking and affordable limbs with ebony, or mahogany shades, the shades of his fellow brothers and sisters. In essence, he is giving back confidence to those who have lost limbs. Enjoy!
Did you know that ancient Egyptians did not only mummify humans, but animals also? Animals such as cats, crocodiles, mongooses, and ibises have been found in Egyptian pyramids. In ancient Egypt, the ibis was a special bird who represented the god Thoth, god of wisdom, magic, writing, hieroglyphs, science, art, judgment, and the dead. For the longest times, scientists could not understand where millions of ibises which had been mummified came from. Now, they seemingly have cracked this mystery.
While some have been discovered alongside human burials, others – most notably the sacred ibis bird – were mummified as part of rituals designed to curry favour with the gods.
More than 4 million sacred ibis mummies have been found in the catacombs of Tuna el-Gebel and 1.75 million have been discovered in the ancient burial ground of Saqqara. The vast majority were votive offerings to the god Thoth, a practice that had its heyday between 450BC and 250BC.
“The ibis was considered [to represent] the god Thoth, the god of wisdom, the god of magic, the god of judgment, writing all sorts of things,” said Sally Wasef, a research fellow at Griffith University in Australia and first author of the research.
“If you had a boss that annoys you and you don’t feel like you are getting a good judgment from him or you want fairness and justice, you go and ask Thoth to interfere and in return you promise to offer him an ibis, a mummified ibis, in his annual feast.”
But the sheer quantity of mummified ibises left experts scratching their heads – where did all these birds come from?
One suggestion is that they were reared on an industrial scale in hatcheries. That idea appears to have some support in ancient texts, such as the writings of Hor of Sebennytos, a priest and scribe in the second century BC, who wrote about feeding tens of thousands of sacred ibis with bread and clover.
To explore the possibility, Wasef and colleagues analysed DNA from 14 mummified sacred ibises found in ancient Egypt and 26 modern samples from across Africa.
… The results, published in the journal Plos One, reveal the level of diversity in the mitochondrial DNA among the ancient birds is similar to that among modern wild birds, and have similar levels of potentially harmful mutations. However, the team says if the ancient Egyptians farmed sacred ibises, the genetic diversity in ancient birds would probably be lower due to high levels of inbreeding.
Wasef said this suggested that, rather than being bred in a mass-farming situation, sacred ibises were tempted to local areas and kept in a natural habitat – or perhaps captured and kept in farms for a short time, ready for sacrifice. “[The most likely thing is ] next to each temple there was like a lake or a wetland – it is a natural habitat for the ibis to live in and if you are giving them food they will keep coming,” she said. Indeed, she notes, there was a swamp near Tuna el-Gebel and the Lake of the Pharaoh near Saqqara. …
In many African countries, from Senegal down to Angola, the manatee is known as Mamy-Wata or the Sirena or a water spirit. It is a sea creature which can also be found in lakes, as well as on the ocean. There is a lot of myths surrounding the creature, and how difficult they are to find. There is also a lot of ideas surrounding their use in local medicines, with a high demand coming from Asia, to the point that they have now become endangered. This article on conservation efforts to save the manatee is from The Guardian. Enjoy!
Once branded ‘rogue animals’, the elusive creatures were on the brink of extinction, but hope is rising for their survival
… For the past 14 years Keith-Diagne has been on a mission to protect the African manatee. There are an estimated 10,000 left, spread across 21 African countries, from the coast of Senegal down to Angola and inland to Chad. …
African manatees are classified as a vulnerable species on the International Union for Conservation of Nature’s Red List. They face many threats, including entanglement in fishing nets and entrapment in dams. In some countries they are heavily poached.
… The animals are so elusive that many locals know them only from myths. In countries such as Senegal, where the animals are revered as auspicious water spirits, poaching is rare. But dams still pose a major threat: the cumbersome mammals can get trapped in narrow passageways and drown.
Keith-Diagne said local dam authorities have been receptive to her proposed modifications of the structures. Politicians have also come on board. In 2014, her husband, Tomas Diagne, also a biologist, successfully petitioned the government to set aside 275 hectares (679 acres) for an aquatic reserve. The area is now home to an estimated 100 manatees as well as hundreds of Adanson’s mud turtles – a species unique to the local lake. The couple are also helping the surrounding communities to develop an ecotourism industry.
Keith-Diagne’s conservation work has extended into other parts of Africa. With the help of a Pew Marine fellowship, she formed a network of nine biologists in Senegal, Gambia, Nigeria, Cameroon and Democratic Republic of Congo to document every manatee captured or killed over three years. The project has already identified one clear trend: Nigeria is a leader in manatee mortality.
Hunters can make up to $2,000 (£1,626) from a single catch in the country, where manatee meat is said to be beneficial for diabetics and their oil is thought to be cholesterol-free. In addition, their penises are believed to cure impotence, their ear bones to ward off bullets, and eyes believed to possess magical powers. The faeces left over in manatee intestines are dried and used to mend broken bones.
According to Nigerian myth, upon encountering a human, a manatee will tickle them until they laugh so hard they drown.
Rumours of manatees breaking fishing nets and capsizing canoes led to their classification as a “rogue animal” in the 1970s – an official classification for animals that threaten human livelihoods, such as crocodiles and hippopotami.
… [Edem] Eniang, [a professor of wildlife resource management at the University of Uyo in Nigeria] and his team often go undercover, posing as buyers to keep tabs on poachers and document manatee killings. They visit schools to teach the importance of conservation and they run TV and radio information campaigns. Such campaigns can and have made a difference. In Cameroon, education and awareness initiatives have pushed manatee hunting to its lowest level.
Aristide Takoukam, the director of the African Marine Mammal Conservation Organisation in Cameroon, gives frequent presentations at schools and organises field trips to Lake Ossa, a wildlife reserve created in 1948.
“I want to teach them to see nature in a different way than their parents,” he says. “I want to show them that in animals, they can also find beauty.”
He also trains fishermen in how to make a living from bee farming and soap making instead of manatee hunting and with the help of an American ecotourism expert, is developing an industry around manatee sightseeing, complete with lakeside bungalows, kayaking and bird watching.
“I want to show them that a manatee is worth more alive than dead,” he says. …
This is encouraging news, and I could not pass on it. The full article is from The Guardian!
Numbers of African black rhinos in the wild have risen by several hundred, a rare boost in the conservation of a species driven to near extinction bypoaching.
Black rhinos are still in grave danger but the small increase – an annual rate of 2.5% over six years, has swollen the population from 4,845 in 2012 to an estimated 5,630 in 2018, giving hope that efforts put into saving the species are paying off.
The painstaking attempts to save the black rhino have included moving some individuals from established groups to new locations, increasing the species’ range and ensuring viable breeding populations, as well as protecting them through stronger law enforcement efforts. Numbers of all of the three subspecies of black rhino are now improving.
“The continued slow recovery is a testament to the immense efforts made in the countries and a powerful reminder that conservation works,” said Grethel Aguilar, acting director general of the International Union for Conservation of Nature, which compiles the global red list of species under threat.
“[But] there is no room for complacency as poaching and illegal trade remain acute threats. It is essential that the ongoing anti-poaching measures and intensive, proactive population management continue, with support from national and international actors.”
The outlook for the other African rhino species is still troubled, according to the update to the red list published on Thursday.
White rhinos are more numerous in Africa but categorised by the IUCN as near-threatened. The outlook for them has worsened in recent years, driven by high levels of poaching in South Africa’s Kruger national park. White rhinos have larger horns than their black counterparts, making them more attractive to poachers, and they are easier to find as they prefer more open habitats.
Pollution, overpopulation of some areas, as well as over-fishing have wreaked all sorts of havoc for the ecosystem of our planet. One such ecosystem being destroyed is the coral reef along the coasts of Africa. Below are excerpts from an article from the Guardian about Kenyan efforts to reclaim their coral reefs, and bring back the lobsters and octopuses. As the marine life is re-established, let’s hope the industrial fishermen stay away!
Three years ago, coral reef along the Kenyan coastline was almost totally destroyed in some areas. Rising surface sea temperatures had triggered devastating bleaching episodes for the fourth time in less than two decades, and with the whitening of coral came a dwindling of marine life. Overfishing only exacerbated the problem.
For coastal communities dependent on the sea for their livelihoods, the degradation of the coral reef and its effect on the marine ecosystem threatened to overturn an entire way of life. In some areas surveyed by theKenyaMarine and Fisheries Research Institute (KMFRI), as much as 60-90% of coral was destroyed.
A fightback was needed and so the institute began working with local communities to rehabilitate degraded coral reefs along the country’s coastline. Among the areas targeted was Wasini Island, a tiny strip of land off Kenya’s south-east coast. The results have been startling.
Women on the island have led an initiative to restore degraded coral that has shown how coral restoration techniques can revive marine ecosystems and create sustainable livelihoods for communities that depend on fishing and eco-tourism.
“The fish have started coming back since the restoration activities began,” says Nasura Ali, of the Wasini Beach Management Unit, which has about 250 members, of whom roughly 150 are women. More than 40 people have been trained in restoration techniques.
A year-long study by the KMFRI had tested the viability of raising coral fragments from areas affected by bleaching events, explains Jelvas Mwaura at the KMFRI’s department of marine environment and ecology. Many of the corals transplanted from coral gardens to degraded reef areas for the study survived, providing new habitats for fish species including jacks, groupers, emperors and sweetlips.
This success led to funding from the Kenya Coastal Development project (KCDP). Locals on Wasini Island have since grown more than 3,000 corals.
Coral reefs provide shelter and breeding grounds for hundreds of species of marine life. Fish populations in waters around the island have increased three times as much as in other areas, says the KMFRI.
… The women of Wasini Island have also been restoring fish populations by cultivating seagrass. Overfishing of certain species, such as trigger fish, had led to the disappearance of seagrass because trigger fish fed on the sea urchins that devoured it. Using gunny bags made of sisal to protect the seedlings and prevent them from getting washed away, the women replanted seagrass seedlings on the ocean floor.
In addition to providing food, seagrass plays a key role in the overall coral reef ecosystem, providing shelter to juvenile fish after they hatch by shielding them from strong waves until they mature and move into the coral reefs.
Ethiopia has launched its first satellite this past Friday December 20, 2019. This is an outstanding feat and we are happy to celebrate with Ethiopian scientists and all Ethiopians. Funny how all western media titled “First Ethiopian satellite launched with the help of China,” as if it was wrong to do collaborations… aren’t most of the scientists at the International Space Station from all over the world and mainly Europe and the United States? Well we celebrate Ethiopia’s achievement. Below are excerpts from the article found on PhysOrg .
Ethiopia’s first satellite was sent into space on Friday, a landmark achievement for the ambitious country that also caps a banner year for Africa’s involvement in space.
A Chinese Long March 4B rocket hoisted the first Ethiopian Remote Sensing Satellite (ETRSS-1) aloft from the Taiyuan space base in northern China.
Scores of Ethiopian and Chinese officials and scientists gathered at the Entoto Observatory and Research Centre outside the capital, Addis Ababa, early Friday to watch a live broadcast.
The 70-kilogramme (154-pound) satellite was developed by the Chinese Academy of Space Technology with the help of 21 Ethiopian scientists, according to the specialist website africanews.space .
It [the satellite] will send back data of the environment and weather patterns in the Horn of Africa—a boon for a country dependent on agriculture and forestry and vulnerable to flood, drought and other climate perils.
“This will be a foundation for our historic journey to prosperity,” Deputy Prime Minister Demeke Mekonnen said in a speech.
It is the eighth launch of an African satellite this year, topping the previous record of seven in 2017, according to Temidayo Oniosun, managing director of Space in Africa, a Nigeria-based firm that tracks African space programmes.
“We can say that 2019 is pretty much the best year in the history of the African space industry,” Oniosun told AFP.
The launch makes Ethiopia the eleventh African country to have a satellite into space. Egypt was the first in 1998.
All told, 41 African satellites have now been launched—38 from individual countries and three more that were multilateral efforts, Oniosun said.
None of those launches has taken place from African soil.
China covered most of the satellite’s $8 million (7.2-million-euro) cost, according to an official involved in Ethiopia’s space programme who spoke on condition of anonymity because he was not authorised to disclose details of the project.
Last August, Ethiopia broke a world record for… not in long distance running, people… but for the most trees planted in a single day in the world. The goal was to plant 200 million trees to fight against deforestation and droughts in Ethiopia. Kudos to the prime minister Abiy Ahmed and to the strong people of Ethiopia.
Enjoy the excerpt below below from Borkena; you will find the full article there.
Prime minister Abiy Ahmed’s administration has been mobilizing for months for what it called “Green Legacy” project which aimed at planting over 200 million trees in a single day.
Government affiliated media, Fana Broadcasting Corporation (FBC), cited the coordinating committee of the project to report that 353,633,660trees have been planted across the country.
Religious leaders, workers, business people, actors, members of the Ethiopian Defense force, senior government officials, students, among others, have participated in the campaign.
[…] Over the last decades, Ethiopia lost much of forest coverage across the country due to deforestation. Currently, the forest coverage is said to be below 3 percent.
Organizers of the green legacy campaign and Abiy Ahmed’s administration pride itself by claiming world record with the 200 million trees in a day campaign.
According to Guinness World Records, the record for individuals was registered in 2001 in Canada. Ken Chaplain planted 15,170 trees in one day in Saskatchewan.
