In a village in the eastern cape of South Africa lies one of the most significant dinosaur sites ever found in the world. The site was discovered when a shepherd, Dumangwe Thyobeka found a large bone on his way to his great-grandparents’ graves, in 2015. He then took the bones to a local dinosaur enthusiast, James Rhalene. Commenting on this discovery " Mr. Rhalene said, "Growing up we were told dinosaurs were a myth, I thought they were only tales our grandparents would tell around the fire at story time", and It wasn't until reading some books that I started to believe they may be real. I've been looking into the existence of dinosaurs since 1982. He added, "You can imagine my excitement at being part of this and discovering them in my own backyard. I am so proud. Books will be written about our small village; the world will come to know of us through this discovery.”

These bones are more than 200 million years old, of around the end of the Triassic era and the beginning of the Jurassic one. When the village elder, Sginyane Ralane came to know about the discovery, he reached out to universities in South Africa for looking into it. The news eventually reached Prof. Jonah Choiniere from the University of Witwatersrand in Johannesburg, and in 2018 Jonah and his colleagues started excavating the site. “It has been one of those places where you sometimes find yourself literally tripping over a dinosaur bone. There are very few other sites I've had the chance to work where we have this richness of fossils.” says Prof Paul Barett, a dinosaur expert at The Natural History Museum, UK, after he joined the team.

A reason why this area is abundant in fossils, Natural History Museum explains, is because of the ancient river systems in the area. The area is arid for most of the year now, and the rivers flow only seasonally. However, in the ancient times, there were vast river systems flowing year-round in the region, with wide, shallow rivers which would consequently form a layer of rock 210 million years old which is up to 500 meters thick in some regions. These rivers supported diverse wildlife, including ancestors of crocodiles, possibly those of turtles and mammals and fish, amphibians and reptile-like animals. The existence of such large rivers meant that dead animals nearby would be buried in sediment before they decomposed.  

This discovery is scientifically important for a number of reasons; the era from which these bones are found is a boundary in which a mass extinction occurred. Prof. Jonah is trying to understand how the animals from before that extinction survived and how they flourished after. In the Triassic era, there were multiple dominating animals, like the crocodiles, big mammal-like animals and dinosaurs. In the Jurassic era, however, the dinosaurs are clearly dominating. Why this happened is unclear, and the rocks and fossils from this site might help with that. There were also other animals along with dinosaurs in this site which make it noteworthy. Of the animals found, there were rauisuchians, which relate to modern-day crocodiles, and were dominant on land during the Triassic. The team also found cyclodonts and dicyclodonts, where the cyclodonts are the early ancestors to all mammals, and dicyclodonts are an even earlier branch of the mammalian family tree.

All of these have a significant impact on the community too; the team signed a memorandum of understanding with the local government with huge. After the signing, local officials visited the site at Qhemega. The team has been trying to use the heavy machinery they had brought for moving fossils for improving access in and to the village. They are also developing a curriculum in high schools to include topics about fossil sites and to add geography to the curriculum, to train the younger generation about the mapping used in excavation and in many other scientific fields especially relevant in the mineral-resource rich South Africa.

So far, this site has only provided benefits for everyone involved; new discoveries and confirming data for the scientific community, and economic access, increased opportunities and a matter for pride for the local community.

How COVID-19 devastated African Safari industry

With COVID-19 wrecking the economies of superpowers like the US and China, Africa is no exception. The continent of Africa is bestowed with rich biodiversity which attracts millions of tourists every year. But due to the pandemic, the safari industry of Africa is in a freefall.

The countries which are visited more often by the international tourists for their remarkable safari experiences include Botswana, Kenya, Namibia, Rwanda, South Africa, Tanzania, Uganda and Zambia. These contribute more than 12 billion US dollars to the economy, according to the United Nations World Tourism Organization (UNWTO).

The tourism industry is one of the most impacted economic sectors due to lockdowns being imposed all over the world. The magnitude of loss came into light when Safaribookings.com, a website for booking safari tours in Africa, ran its fourth monthly survey. The bookings this year declined by a massive 75%. “We don’t have bookings, and we don’t have money to pay salaries for staff, office rental etc. Things are really bad” says a Kenyan safari vehicle operator. Thousands of the people depending on services related to industry lost the livelihood due to this downturn..

Khimbini Hlongwane, the proprietor of a small tour business in Kruger National Park of South Africa, is devastated as he had invested all his savings to purchase a new minibus for his visitors. “It hasn’t moved since the day we bought it,” he says.  Leon Plutsick, who owns a lodge in Manyeleti private game reserve adjacent to the Kruger National Park says that he is barely surviving on the remaining meagre reserves. What used to be a lodge packed with tourists, is now replaced by Baboons. A tour guide and father of four, Sipho Nkosi, who earns a decent amount of 550 rand per tour, finds himself and his family in troubled waters. “We’d saved some money. But it's running out, so we’ll start starving” he says.

Not only the local communities but also the prolific wildlife of Africa is bearing the brunt of the pandemic. Tourist funds play a key role in conservation projects. Jackson Looseyia, a conservationist and lodge owner at Maasai Mara says, “In conservation terms, it is a crisis. We have no money coming in whatsoever, and the future is so bleak”.

Many of the families dependent on ecotourism see no option but to turn towards poaching as a means of survival. This further poses a threat to the species. Dickson Kaelo, CEO of Kenya Wildlife Conservancies Association says, “Due to the high rates of unemployment, commercial bushmeat has become rampant in some areas. Recently there were even cases of giraffes killed for commercial purposes”. At least six black rhinos, who might face extinction soon, were killed by poachers in Okavango Delta, Botswana, in the month of March. Efforts are being taken to evacuate the remaining rhinos and shift them to safer places.

The Tourism Business Council of South Africa is urging the government to reopen the national parks and sanctuaries for the public, latest by September. However, the South African government states that the tourism industry is not likely to reopen before 2021.

Kenya, Namibia and Rwanda are not open for tourists. Zambia is permitting tourists but with an obligatory two-week quarantine. Tanzania has imposed no such requirements. However, tourists will think twice before going on any international trips as we have not yet won the fight against coronavirus.

All this has left the people associated with the ecotourism sector in Africa in a dark tunnel with seemingly no end at the moment.
