South Sudan says its 6M antelope make up world’s largest land mammal migration, but poaching on rise

Seen from the air, they ripple across the landscape — a river of antelope racing across the vast grasslands of South Sudan in what conservationists say is the world's largest land mammal migration.

The country's first comprehensive aerial wildlife survey, released Tuesday June 25, found about six million antelope.

The survey was conducted over a two-week period last year in two national parks and nearby areas.

It relied on spotters in airplanes, analysis of nearly 60,000 photos and tracking of more than a hundred collared animals over about 46,000 square miles (120,000 square kilometers).

The estimate from nonprofit African Parks, which conducted the work along with the South Sudan government, far surpasses figures for other large migratory herds, such as the estimated 1.36 million wildebeests surveyed last year in the Serengeti region straddling Tanzania and Kenya.

But they warn the animals face a rising threat from commercial poaching, in a nation rife with weapons and without strong law enforcement.

"South Sudan is the largest, large mammal migration in the world, at this stage," says Larry McGillewie, a pilot working for African Parks.

“This is a large migration, which needs to be protected."

The migration stretches from east of the Nile in Badingilo and Boma national parks into neighboring Ethiopia — an area roughly the size of the U.S. state of Georgia.

It includes four main antelope, the white-eared kob — of which there are some 5 million — the tiang, the Mongalla gazelle and bohor reedbuck.

The survey says some animals have increased since a more limited one in 2010, including the white-eared kob.

But it describes a “catastrophic” decline of most non-migratory species in the last 40 years, such as the hippo, elephant and warthog.

Associated Press journalists flying over the stunning migration of thousands of antelope saw few giraffes and no elephants, lions or cheetahs.

Trying to protect the animals over such a vast terrain is challenging.

In recent years, new roads have increased people's access to markets, contributing to poaching.

Years of flooding have meant crop failures that have left some people with little choice but to hunt for food.

African Parks estimates some 30,000 animals were being killed each month between March and May this year.

“We kill the animals because the crops have failed," says Wilson Ubaa, a resident in Lafon County.

"We don’t kill them when the harvest is good."

The government hasn't made a priority of protecting wildlife.

Less than one percent of its current budget is allocated to the wildlife ministry, which said it has few cars to move rangers around to protect animals.

Villagers nestled in and around the parks told The AP they mostly hunted to feed their families or to barter for goods.

A newly paved road between Juba and Bor — the epicenter of the illegal commercial bushmeat trade — has made it easier for trucks to carry large quantities of animals.

Bor sits along the Nile, about 27 miles (45 kilometers) from Badingilo Park. In the dry season, animals coming closer to the town to drink are vulnerable to killing.

Officials at the wildlife ministry in Bor told AP the killing of animals had doubled in the last two years.

Even when those involved in the industry are caught, the consequences can be minor.

A few years ago, when wildlife rangers came to arrest animal seller Lina Garang, she says they let her go, instead telling her to conduct business more discreetly.

Thirty-eight-year-old Garang says her competition has only grown, with 15 new shops opening along her strip to buy and sell animals.

“There is high competition, and there are a lot of meat sellers," she says.

"I don't have anything, my business has broken. How will we feed the children?"

Part of the challenge is that there is no national land management plan, so roads and infrastructure are built without initial discussions about where they are best placed.

The government has also allocated an oil concession to a South African company in the middle of Badingilo that spans nearly 90% of the park.

African Parks is trying to square modernizing the country with preserving the wildlife.

The organization has been criticized in the past for not engaging enough with communities and taking an overly militarized approach in some of the nearly two dozen areas it manages in Africa.

The group says its core strategy in South Sudan is focused on community relations and aligning the benefits of wildlife and economic development.

One plan is to create land conservancies that local communities would manage, with input from national authorities.

Meanwhile, African Parks has set up small hubs in several remote villages and is spreading messages of sustainable practices, such as not killing female or baby animals.

"The message now is hunting is not bad, that was the past message that we used, but too much hunting is bad, because it will destroy all the species," says David Liwaya, a Lafon site officer working for African Parks.

"We need to engage them slowly, to understand about the conservation through that approach."

Hopes of tourism around the animals may take a while.

For now, there aren't hotels or roads to host people near the parks, and the only option is high-end trips for what one tour company official called a “high-risk” audience.

There’s fighting between tribes and attacks by gunmen in the area, pilots told AP they’ve been shot at by people while flying overhead.

Locals trying to protect the wildlife say it’s hard to shift people's mentality.

In the remote village of Otallo on the border with Ethiopia, young men have started buying motorbikes.

What had been an all-day trip on foot to cross the border to sell animals now takes just five hours, allowing them to double the number of animals they take and make multiple trips.

One of them, Charo Ochogi, says he'd rather be doing something else, but there are few options, and he's not worried about the animals disappearing.

“Here in this village, I have a motorcycle and my future plan is to transport bushmeat for commercial and other essential business activities," he says.

The migration is already being touted as a point of national pride by a country trying to move beyond its conflict-riddled past.

Billboards of the migration recently went up in the capital of Juba, and the government has aspirations that the animals may someday be a magnet for tourists says Peter Alberto, Undersecretary for the Ministry of Wildlife Conservation and Tourism:

“So, you know, we'll try our best to demonstrate to the whole world that at least we are trying our best to make the wildlife in South Sudan known to the rest of the world."

South Sudan has six national parks and a dozen game reserves covering more than 13% of the terrain.

Out on dry land: Water shortage threatens species in Ruaha National Park in Tanzania

Out on dry land: Water shortage threatens species in Ruaha National Park in Tanzania

Climate change is not the only cause of arid landscapes. A research team led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) has investigated the consequences of increased water abstraction for agriculture and livestock farming from the Great Ruaha River.

This river, which used to flow continuously, now dries up for months at a time. The scientists showed that some herbivores were able to partially compensate for the temporary lack of water through their diet, whereas others had little or no ability to do so. In particular, African buffalo, plains zebra and waterbuck were sometimes severely restricted in their habitat use as a result.

The effects of  on Ruaha National Park's biodiversity are described in an article in Wildlife Biology.

Although  across Africa aim to protect wildlife from the direct negative impacts of human activities such as bushmeat hunting, poaching, and livestock farming, wildlife populations are declining in many national parks. This is partly due to indirect human impacts, such as water abstraction from rivers outside national parks.

When little or no rain falls during the  in African countries, temporary water sources such as puddles, rain-filled depressions, and pools dry up. Many  respond by moving to the area around the remaining water.

"We wanted to find out which animal species cope best with water scarcity and which survival strategies they develop," explains first author Dr. Claudia Schmied, whose doctoral thesis on the consequences of water abstraction from the Great Ruaha River for the large animal community was supervised by the Leibniz-IZW. "During three dry seasons, we investigated which herbivores in Ruaha National Park changed their location and moved to sites where they find reliable water sources."

Some herbivores were more sensitive to water shortages than others, the scientists confirm. "There are animals that can partially compensate for the lack of drinking water through their diet, or have mechanisms to regulate their body temperature to limit water loss through feces and urine."

"Our results show that omnivores such as the crowned duiker and the warthog stayed put, so that their distance to the nearest water source in the late dry season significantly increased, so they did not follow the water," says Schmied. This was also the case for impala (Aepyceros melampus) and greater kudu (Strepsiceros zambesiensis), which have a mixed vegetarian diet.

"Our results suggest that these species are better able to cope with the decline in surface water than, for example, the African buffalo."

As grazers, African buffalo (Syncerus caffer), plains zebra (Equus quagga), and waterbuck (Kobus ellipsiprymnus) need constant access to drinking water. Omnivores such as the warthog (Phacochoerus africanus) and the crown duiker (Sylvicapra grimmia) have a broader diet, eating underground plants such as tubers and rhizomes, fruits, and smaller animals—food that contains more water than the grass during the dry season.

This advantage makes these species less dependent on access to drinking water.

The scientists mapped where the animals went in the early and late parts of the dry seasons to record in which locations they spent their time. The results were consistent with the expectation that some species were moving closer to the few remaining water sources in the upper Great Ruaha River.

"Our spatial analyses showed that the African buffalo completely withdrew from the study area during the dry season. These grazing animals are particularly dependent on water, as the moisture content of the grazed grasses is low during the dry season," says Professor Stephanie Kramer-Schadt, head of the Department of Ecological Dynamics at the Leibniz-IZW.

"The African buffalo in Ruaha National Park, therefore, loses large parts of its habitat during the dry season," adds Dr. Marion East, a scientist in the Department of Ecological Dynamics at the Leibniz-IZW and supervisor of Schmied's doctoral work.

At the end of the dry season, water-dependent herbivores increasingly congregated around the shrinking waterholes on the upper reaches of the Great Ruaha River. Larger predators, such as lions and leopards, move into these areas and consume a part of these populations.

However, little is known about the long-term effects of the loss of water from the Great Ruaha River on the ecology of Ruaha National Park and its high biodiversity. Increasing concentrations of animals around remaining water sources may facilitate the transmission of pathogens, the scientists suggest.

The high levels of water loss could also lead to a more rapid decline in nutrient quality and riparian vegetation, which in turn could affect the health of herbivores and have negative consequences for their populations.

Ruaha National Park in Tanzania was established in 1964 and expanded in 2008 to include the Usangu Game Reserve. Covering an area of 20,226 square kilometers, it is one of the largest national parks in Africa. It is considered to be one of the most important wildlife habitats in Africa. The Great Ruaha River is one of Tanzania's largest rivers and is regarded as the ecological backbone of Tanzania before it flows through Ruaha National Park (Tanzania), one of Africa's largest national parks.

Fossil fuel extraction is destroying the planet. As the climate crisis accelerates, even the world’s major oil and gas companies now openly accept the need to transition to sustainable sources of energy for the sake of our future.

Two years ago, the International Energy Agency declared that the key aim set out in the Paris Agreement – to limit global heating to 1.5C – could only be achieved by halting all investment in new oil and gas infrastructure worldwide.

Yet money continues to be poured into fossil fuels – and these investments have been rising in Africa, where an area larger than France and Italy combined has been licensed for oil and gas exploration since 2017. Nor does this look set to slow down: oil and gas companies are currently searching for new hydrocarbon reserves in 45 African countries.


One of these is the Democratic Republic of Congo (DRC), which last May announced an auction for the rights to explore for oil and gas within its borders, despite protests from national and international non-governmental organisations. The government says the country may have up to 16bn barrels of oil, and that some of those reserves lie under the rainforest. Experts say the project is a “carbon bomb” that threatens one of the last and most critical frontiers in the battle against climate breakdown: the Congo Basin rainforest.
What’s the Congo Basin?

The Congo Basin is the largest expanse of intact rainforest outside of the Amazon. Years of rampant deforestation in the Amazon, however, means more emissions are released due to fires and agriculture than are captured by the trees. This means the Congo Basin is now the only tropical rainforest in the world with enough trees still standing to absorb substantially more CO2 than it emits.

It stretches across six countries but the majority of it is in the DRC, where it is home to 15.2 million people. Last July, the DRC government announced that huge parts of this land would be parcelled up, with the rights auctioned off for private companies to explore for oil – and TBIJ has revealed the process to be plagued with apparent preferential treatment and backroom deals.

Within the Congo Basin rainforest is also the world’s largest tropical peatland complex. Again, most of this is in the DRC.

So what are the peatlands?

Congo’s peatlands are basically swampy rainforests. The Cuvette Centrale area, where they’re located, is home to more than 11 million people, many of whom belong to nomadic and semi-nomadic Indigenous communities who rely on the peatlands for their livelihoods. They are also some of the world’s richest forests for wildlife, including major populations of elephants, bonobos, monkeys and crocodiles.

But peatlands are also vital for the climate, because they store huge amounts of carbon. Altogether, the Congo Basin’s peatlands store the equivalent of three years’ global emissions from fossil fuels. Disturbing the land could begin the release of the vast amount of carbon stored underneath, flipping the peatlands from a hugely valuable absorber of CO2 to a catastrophic emitter.

What does this have to do with fossil fuels?

Parts of the forest also fall on the land being auctioned off. Thirteen blocks overlap with protected areas and, most importantly, three overlap with Congo’s peatlands.


So far the blocks have been auctioned off for oil exploration – the stage before drilling.
So they might not end up drilling for oil?

No – although that might come later. But even exploring for oil opens up the forest and peatlands to enormous destruction.

The current lack of infrastructure means the Congo Basin has not suffered the sort of rampant deforestation we see in the Amazon. But the construction of roads, pipes, buildings and everything else needed to explore for oil would open up the land to commercial hunters, poachers and illegal loggers. It could also lead to the disturbance of the peatland ecosystem. And that’s all before the companies discover whether there are oil deposits to drill into.
Would this affect the carbon under the ground?

Yes. The three areas of peatland being auctioned off store a total of 1.67bn tonnes of carbon, which if disturbed could release more than the US’s annual emissions.

This means that, even before factoring in the usual concerns associated with oil drilling – the emissions caused by both the drilling process itself and then the burning of the oil that is found – simply disturbing this land could prove catastrophic for the planet.

And the peatlands are only a small part of the auction. Three blocks overlap with peatlands but there are 30 oil and gas blocks in total, 13 of which encroach on protected areas.

Who will benefit from extracting oil?

With climate experts, local communities and organisations such as Greenpeace having voiced fierce opposition to the auction, the government has so far struggled to attract bidders. A number of major companies, such as TotalEnergies, have said they will not take part.

But the auction is not without domestic support. There are those who argue that the DRC has a right to use the proceeds from its natural resources, and that doing so could drive development in one of the world’s poorest countries.
Who is most at risk from this auction?

Most immediately, the 75 million people from more than 150 ethnic groups who live in the Congo Basin’s forests and whose futures depend on the health of their surroundings. Many fear oil exploration will force them from their land and pollute the rivers and forests they rely on for survival.

But in the long term, all of us are at risk. If the exploitation of this land goes ahead, the implications for the climate are huge: the Congo Basin is a vital resource in attempting to balance out the planet-heating CO2 we continue to emit.

Jean Bolengu Ekunja drove his spear into the ground. “We won’t compromise,” he told the crowd gathered in Baringa, a village deep in the Congo Basin rainforest. “If oil activity is what they are going to do here, they will have to kill me first, as the chief. Then they will have to slaughter all the population!”

The Democratic Republic of Congo is auctioning rights to explore for oil and gas in large swathes of rainforest and other protected areas across the country. Baringa is one of scores of communities affected. The process has sparked fierce yet familiar debate about environment and development and set the stage for a legal fight over community rights, with many local people opposing extraction.

DRC’s hydrocarbons minister, Didier Budimbu, has said the country needs to extract its oil and gas “so that our children can eat and we can develop our economy”. It is the latest attempt to exploit fossil fuel resources in one of the world’s poorest countries, where almost two-thirds of the population survive on less than $2.15 a day, the international poverty line.

Many previous attempts to exploit DRC’s fossil fuel reserves have ended in failure, beset with scandal and scuppered by officials cancelling contracts.

This time around, the DRC has promised the auction will be transparent, impartial and competitive. But TBIJ revealed a process plagued with apparent preferential treatment and backroom deals.

Community opposition

Some of the oil blocks up for auction lie within the Congo Basin rainforest, which is peppered with small farming and fishing communities. DRC law requires the government to get the opinion of local people before any project or activity that may have an impact on the environment. However, the people here say they have not been asked about the auction.

‘We owe our survival to the forest. We refuse oil exploitation’

A few hours upstream from Baringa and several kilometres further into the forest is Lisoko, a farming community. With no phone network or radio coverage, the community has little access to news about the oil block auction. Nadine Bolumbu, the chief of this and six neighbouring villages, said no one apart from Greenpeace had told them about the auction. She said the villagers’ position was clear: “We owe our survival to the forest. We refuse oil exploitation in our group.” Budimbu and the Ministry of Hydrocarbons declined to comment.

The people in Lisoko gather cassava leaves and fat yellow caterpillars from the swampy forest surrounding the village, where African teak trees loom out of the water, some reaching up to 50 metres high. This tangle of trees serves as a hunting ground for wild boar, antelopes and other bushmeat, and villagers catch fish in its pools and streams. Bamboo and thick branches provide structures for their one-storey homes, many built from earth packed and cooked into bricks.

The lack of infrastructure raises questions over how realistic oil exploration is. After a flight from Kinshasa, Lisoko is a two-day trip by motorboat up the River Congo and its tributaries before heading into the forest. There are few roads here, just narrow tracks for motorbikes to whip along, their drivers ducking to avoid low branches and fallen trees. Goods are transported via the river, from live goats on makeshift rafts, to barges piled high with timber.

Exporting oil from this area would involve building hundreds of miles of pipeline through dense rainforest. Similar licences acquired from the government in the past have remained unused for years due to the huge investment they require.

Vincent Rouget, a director at the consultancy Control Risks, said the current government may have intended to raise funds from the auction before the upcoming election, slated for December. Instead it has become an election issue, with the leading opposition candidate Moïse Katumbi stating that he would scrap plans to explore for oil in the Congo Basin if he wins.
The worst place in the world to drill for oil

That opposition stretches beyond the DRC. Last year, the US climate envoy John Kerry asked the government to withdraw some of the oil blocks to protect the tropical rainforest – the last in the world with enough trees to absorb more carbon than it emits. International and Congolese environmental organisations have called for the government to scrap the auction altogether.

At least 13 of the blocks overlap with protected areas, according to Greenpeace Africa. That includes the world’s largest tropical peatlands, near Lisoko, which fan out from tributaries of the River Congo in the north-west. It has been described by experts as the worst place in the world to drill for oil, because peatlands lock-in partially decayed plant matter that, if disturbed, could release vast amounts of carbon, dramatically adding to global heating.

‘After this exploitation, what will be left here? They’ll abandon the land with the craters, there will be water pollution, all the animals will flee’


It is also an area rich in wildlife such as bonobos, crocodiles and forest elephants. Amid the trilling of crickets, kingfishers and hornbills, the government's promise to ensure that any oil exploration is done responsibly rings hollow. Even the highly diplomatic chief of the nearby bonobo reserve, who refused to answer questions on the auction, conceded: “You cannot do oil exploration without consequences.”

Sitting under a palm-roofed shelter out of the punishing midday sun, Albert Ifaso Bonguli, one of Lisoko’s village elders, asked: “After this exploitation, what will be left here? They’ll abandon the land with the craters, there will be water pollution, all the animals will flee.” He was unconvinced that oil would bring jobs to these communities, which desperately need funds to send their children to school and pay for medical care.

Few people here end up in secondary education, where final exams cost more than $70 – a huge sum for people whose main source of income is from the surplus bushmeat, vegetables and fish they can sell in local markets. “The villagers don't know anything about this kind of work,” Ifaso said. “The income from the oil will not benefit the Congo, only the investors who are financing the exploitation.”

The people here have already seen the arrival of the logging business, but there is little evidence that it has alleviated poverty. Joe Eisen, executive director of Rainforest Foundation UK (RFUK), said: “The promised trickle-down benefits of industries, such as commercial logging, in the form of secure employment, tax revenues, infrastructure and development rarely materialise in rural areas, with the benefits mostly captured by corrupt officials and political elites.”

RFUK has been helping communities secure legal rights to remain in the forests as their protectors. If done in the right way, Eisen said, “this currently offers the best and most equitable way to protect forests in a way that supports local development in rural areas”.

Research has shown this often results in better conservation of the forest and costs less than creating dedicated protected areas. Back in Lisoko, Bolumbu says: “We protect our forests ourselves. If you want to help us, bring humanitarian aid by promoting jobs for young people, but do not touch the forest.”
Protecting Indigenous rights

Further into the forest, but still inside the boundaries of blocks parcelled up for investment, is the Balumbe community – an Indigenous people who have long been discriminated against. They have an even stronger claim against the government’s drive to sell off rights to explore for oil.

Last year, under pressure from campaigners, Felix Tshisekedi’s government introduced a new law to tackle discrimination and abuses against Indigenous people such as the Balumbe. This requires the government to obtain the free, prior and informed consent for activities that could displace them from their land – a weightier obligation than the requirement to consult the population, which echoes international standards. Thomas Fessy of Human Rights Watch said: “Now that it’s been adopted, let’s make sure that it is fully implemented and that it brings change into the lives of Indigenous communities.” He said the auction of the oil blocks could be an important test case.

The law came into force in February and no attempt has yet been made to gain the Indigenous communities’ consent for the oil auction. Observers say that could significantly disrupt the auction.

Augustin Mpoyi, a leading environmental lawyer in DRC, said if Indigenous people opposed oil exploitation, the government may choose to seize the land. “The state may feel that the revenues that oil can generate are significant and could be put to public use, and it may halt the objection. But it's going to take time. It’s going to delay oil exploitation even more.”

The government has so far struggled to attract bidders for the oil blocks and some major companies, such as TotalEnergies, have said they will not take part. Finding funding and insurance for projects to extract oil in the rainforest may also prove difficult. Many financial institutions have committed to ensuring that any projects they support have the free, prior and informed consent of affected communities. According to Greenpeace, Generali, Hannover Re, Talanx and Zurich have ruled out providing cover for oil and gas blocks in the DRC. Hannover Re said this was due to “expectations and exclusions” relating to environment, social and governance issues.

The lack of consent from the communities that TBIJ visited was evident. They may not have been consulted, but many have heard rumours of the auction. Seeing a group of outsiders speeding through the village on motorbikes and assuming they were there to take the oil, local people shouted “Thieves!”, “We refuse!” and “Get out of here!”

Back in Baringa, Ekunja said his village has not been consulted on the auctions. But they had discussed them – and their answer was clear. “Non! N-O-N!” he shouted, drawing cheers from the crowd.

New study identifies illegal hunting as a threat to China’s wildlife and global public health



Peer-Reviewed Publication

PRINCETON SCHOOL OF PUBLIC AND INTERNATIONAL AFFAIRS




Illegal hunting and trading of wildlife in China is becoming a significant threat to biodiversity and public health, according to a new paper by a team of researchers that includes two scholars from the School of Public and International Affairs. It is the first comprehensive assessment of this issue for China.

The paper, "Assessing the illegal hunting of native wildlife in China," appears in Nature today. Its co-authors are Dan Liang, Xingli Giam, Sifan Hu, Liang Ma, and David S. Wilcove. Liang is an associate research scholar at SPIA's Center for Policy Research on Energy and the Environment (C-PREE), and Wilcove is a professor of ecology, evolutionary biology and public affairs, and the High Meadows Environmental Institute, as well as SPIA's acting executive vice dean. Giam, an associate professor at the University of Tennessee in Knoxville, received his doctorate in ecology and evolutionary biology from Princeton. And Ma, currently an associate professor at Sun Yat-sen University in Shenzhen, China, was an associate research scholar at C-PREE. Hu is a postdoctoral researcher at Sun Yat-sen University.

The researchers used Chinese court documents that tracked convictions for illegal hunting in the country, and then created a series of models to predict how much more widespread the extent of illegal hunting is beyond the individuals who were caught and prosecuted. 

The court documents revealed a total of 9,256 convictions for the illegal hunting of more than three million individual animals from 2014 to 2020. Those animals represented more than 20% of China's bird, mammal, reptile, and amphibian species, and included almost a quarter of the endangered species in those categories. 

"We were very surprised by the large number of species that were illegally hunted in the space of just six years," Liang says. 

"But of course," adds Wilcove, "only a fraction of the actual number of hunting incidents results in prosecution and conviction, so that means these numbers must be the tip of the iceberg. And so, we then applied various statistical methods to show that, in fact, the iceberg is very large indeed." 

There is limited evidence in the field to suggest how much bigger the metaphorical iceberg is, but the researchers cited some of their ongoing work that indicates it's optimistic to think that even 1% of all illegal hunting incidents are detected and prosecuted. 

The researchers were more conservative for this paper, though: for an extrapolation analysis, they assumed that 10% of all illegal hunting incidents had been detected and prosecuted and then estimated the total number of species that were likely hunted. They concluded that at least 28% of China’s native terrestrial vertebrate species, including 40% of its birds, may have been taken during this period. They further identified an additional 781 species, including more than 90 threatened species, that were likely to have been targeted by hunters over the course of the six years. 

"Illegal activities are inherently very difficult to study because, by definition, people don't talk about them or practice them out in the open," Wilcove says. "It's quite a scientific challenge."

The paper shows that the illegal hunting incidents were widespread across the country, though there was a higher concentration in the areas closer to cities, which suggested that the illegal hunting was potentially done for commercial purposes and resell opportunities. “These sorts of spatial analyses can provide critical insights about the locations and habitats where illegal hunting is most intense, and they may also tell us something about the motivation behind the hunting,” notes Giam.

Additionally, the researchers found that only 5% of convictions accounted for 90% of the individual animals that had been illegally hunted, which suggested that large commercial poaching operations were responsible for much of the loss of wildlife. 

The paper is clear that the illegal hunting of wildlife is a threat to China's biodiversity and creates a potential public health risk to the people of China because of the possibility of transmission of diseases from hunted animals to people. The researchers also note that the problem does not stop at China's borders. 

"The rest of the world should also be concerned," Wilcove says. "First, the loss of biodiversity in China is a loss of biodiversity for the whole world. Second, there's no reason to believe that China is unique in terms of this problem. In fact, there's evidence of hunting depleting wildlife populations in many parts of the world. And third, disease outbreaks stemming from the wildlife trade have the potential to escape the borders of any one country." 

Liang believes the approach the research team took in this study could be used to investigate the problem of illegal hunting in other countries. However, the actual results of the research in this paper stand alone as they relate to the problem in China and should not be used to characterize what’s happening in other countries. 

"Illegal hunting is clearly a threat to China’s wildlife, but we also have to recognize that China is also doing a lot of things to address it," Liang says. He cites the Chinese government recently amending the National List of Protected Animals of China by adding 517 species, including 31 endangered species predicted by this study to be at high risk of being targeted by hunters. The country also enacted a ban in the early days of the COVID-19 pandemic on the consumption of "wild-caught species," and it has deployed public information campaigns encouraging a reduction in the demand for wildlife products. 

The researchers say they hope their study will generate additional interest in China in the problem of illegal hunting and will inspire other scientists to study this issue in other countries.

The death of a lion in Kenya’s picturesque savannas rarely tugs at people’s hearts, even in a country where wildlife tourism is a key pillar of the nation’s economy. But when one of the most tracked male lions in Kenya’s famous Masaai Mara was killed on 24 July 2023 the world took notice. Known as Jesse, he was killed during a fight with a coalition of three male lions from a rival pride, drawing attention to the brutally risky and dangerous lives of male lions.

Lions are organised in family groups known as a pride. Each pride is comprised of several related lionesses. One or more adult male lions will also be present. In the public imagination, male lions are better known by their popularised image as kings of the jungle. Their bravery, strength, and size (only tigers are larger) fits this profile.

But in reality, male lions live a life far more vulnerable. One in two male lions die in the first year of life. From the moment a male lion is born it faces a gauntlet of challenges – from snakebite and hungry hyenas to infanticide at the hands of other male lions.

If a male lion makes it out of their first year of life, and then to independence at around 3, they leave their pride for a period of nomadism. Nomads lead a dangerous existence, skirting the territories of established male coalitions. Out there on their own, few will make it to the age of 10.

A young male lion rests in the branches of a tree in Uganda’s Ishasha sector. This particular cub was the son of a three male coalition of lions.

At no time, it seems, is the male lion safe. We know from the evidence collected by the Kenya Wildlife Trust, resident guides, and tourists that Jesse administered and received many beatings from other male lions. We also know that Jesse, who lived to the ripe old age of 12, was eventually killed by three younger, stronger lions. Life comes full circle: killers frequently become victims themselves, of younger, brasher lions, or those in larger and thus more powerful coalitions.

We are three researchers with over 50 years of combined experience in big cat ecology, conservation, and the complexities of people and wildlife living together.

We base our commentary on the extensive information gathered by conservation organisations, independent scientists and tourism guides working in the Maasai Mara. Information on Jesse has been collected mainly through sightings data compiled by these entities over time.

Often the survival of male lions will be dictated by the size and strength of their coalitions, and the make up of the lion landscape at large. This sometimes has bearing for conservation especially when lions stray out of national parks or when male lions are hunted after leaving the safety of a protected area.

The trials of a young lion

A young male lion’s biggest threat is his exposure to other male lions that aren’t their father or uncle. A host of studies from the Serengeti in Tanzania to Zimbabwe show that the most significant single cause of lion mortality in the first year of a lion’s life is attributed to other male lions that kill them during infanticide.

This involves incoming males seeking out and killing the cubs of other males or driving young males away, and attempting to take over prides. Killing cubs accelerates the onset of oestrus in pride females and so is likely to increase the reproductive success of incoming males.

Most lions that get pushed out of their pride when very young don’t survive.

Cubs that survive to independence – around 3 years of age – must leave their pride for a period of nomadism. During this time, they join up with cousins, brothers, and sometimes unrelated males of similar age to form what biologists term ‘coalitions’. The power of coalitions increases dramatically with the size of the group. This power can be defined by the number of different prides these coalitions are likely to rule, the number of offspring they will sire, and the number of times they will successfully be able to defend their prides from violent incursions from neighbouring male lions and their coalitions.

The tradeoff of larger coalitions is a watering down of a male lion’s reproductive opportunities.

Examples of such powerful coalitions include the six-strong Mapogo, and five-strong Majingilane from South Africa. There is also the Lake Quintet coalition from Ngorongoro Crater in Tanzania.

Contrastingly, Jesse had only one coalition mate, a lion known as Frank. The two were strong enough to kick out the duo of Dere and Barrikoi from the Offbeat pride in May 2014. After his coalition mate Frank disappeared, Jesse left the Offbeat Pride and led a largely nomadic lifestyle except when he unsuccessfully tried to take over the Rakero pride and even fought with his own son Jesse 2.

Three laws of the wild


Mate, protect, fight. These are the three tenets most male animals live and die by in the animal kingdom and this could not be truer for male lions. When male lions are in the prime of their lives somewhere between 5 and 9 years of age they will attempt to have as many cubs as they can. And they will do their best to protect and guard over as many prides as possible.

But there is a fine line between holding tenure over many different prides, and successfully being able to defend them and their young. When fights do breakout between male lions they are usually over territorial and breeding rights.

At times they are mere squabbles between coalition mates. At other times, the battles are big enough to cause rifts and splits within coalitions. But in most cases fights are between rival coalitions. During these fights lions engage in a suite of bodily and olfactory engagements including posturing, roaring and growling, swatting, and biting, and even urination and territorial demarcation.

For conservation: look to the lionesses

When it comes to the conservation of the lion species it is important to look to the lionesses. They are the sentinels of a populations health, specifically the number of animals in a group, and more importantly the ratio of lionesses to lions. Healthy populations can expect ratios of roughly 2 females for every male, but when under pressure due to poaching, killings by cattle farmers and a loss of prey these ratios invert towards males.

The story of Jesse highlights how, in spite of their status as king of the beasts, lions are vulnerable. While in this instance, the cause of death was another lion, much more commonly, lions die at the hands of humans. This can be through being shot or poisoned to protect livestock, being poached for their body parts or being caught as by-catch in traps and snares set for other animals by bushmeat poachers.

On the plus side, the fascinating pride dynamics and trials and tribulations of individual lions can help capture the public’s imagination and foster a love for the species and other wildlife. Although human pressures are high, Kenya retains a large lion population and a suite of iconic wildlife areas. These assets are a great source of pride for many Kenyans, and rightly so.

COP15
Why biodiversity is good for our health

17 December 2022


The natural world has gifted humanity with untold health benefits, and it is believed that it harbours many more undiscovered health breakthroughs. However, we risk losing these benefits, if we continue to degrade the environment.

The UN biodiversity conference, COP15Opens in new window, is due to wrap up on 19 December. This weekend, we are looking at some of the ways that humanity is reliant on a healthy and thriving global ecosystem.

One million species are now said to be at risk of extinction, and if species losses continue to mount, ecosystem functions vital to human health and life will continue to be disrupted.

Ecosystems provide goods and services that sustain all life on this planet, including human life. While we know a great deal about how many ecosystems function, they often involve such complexity and are on a scale so vast that humanity would find it impossible to substitute for them, no matter how much money was spent in the process.

The Living Laboratory

The majority of prescribed medicines in industrialized countries are derived from natural compounds produced by animals and plants. Billions of people in the developing world rely primarily on traditional plant-based medicine for primary health care.

Many cures from nature are familiar; painkillers such as morphine from opium poppies, the antimalarial quinine from the bark from the South American cinchona tree, and the antibiotic penicillin that is produced by microscopic fungi.

Microbes discovered in the soil of Rapa Nui (Easter Island) fight heart disease by lowering cholesterol. AZT, one of the first anti-HIV/AIDS drugs, came from a large shallow-water sponge that lives in the Caribbean, and happens to be the same sponge that yielded antivirals to treat herpes and serves as the source for the first marine-derived anti-cancer drug to be licensed in the US.

A crucial reservoir for future cures

To date, only around 1.9 million species have been identified (and in many cases barely studied). It is believed that there are millions more that are completely unknown.

Everything alive is the result of a complex “living laboratory” that has been conducting its own clinical tests since life began – approximately 3.7 billion years ago. This natural pharmaceutical library harbours myriad undiscovered cures, if only we don’t destroy them before they’re recognized.

Take the polar bear, now classified as “threatened”. As its Arctic habitat melts due to climate change, the world’s largest terrestrial predator has become an icon of the dangers posed by rising global temperatures. It might also be an icon for health. Polar bears amass huge volumes of fat before hibernating. Despite being fat to a degree that would be life-threatening to humans, they are apparently immune to Type II diabetes. They remain immobile for months, yet their bones remain unchanged. While dormant they do not urinate, yet their kidneys are undamaged. If we understood and could reproduce how bears detoxify waste while hibernating, we might be able to treat - and perhaps even prevent - the toxicity from kidney failure in humans.

Currently 13 per cent of the global population is clinically obese, and the number of Type II diabetes sufferers is predicted to rise to 700 million by 2045. Over the course of their lifetimes, 1 in 3 women over the age of 50, and 1 in 5 men will experience osteoporosis-related bone fractures. In the US alone, kidney failure kills more than 82,000 people and costs the US economy $35 million a year. Polar bears have naturally developed ‘solutions’ to these problems - Type II diabetes from obesity, osteoporosis from being immobile, and toxicity from kidney failure - all of which cause misery to millions.

Coral reefs and morphine

Another example is from coral reefs, sometimes referred to as “rainforests of the sea” due to their high biodiversity. Among the myriad inhabitants of these reefs are cone shells, a predatory mollusc that hunts with darts that deliver 200 distinct toxic compounds.

The drug Ziconotide exactly copies one cone shell’s toxic peptide, and is not just 1,000 times more potent than morphine, but also avoids the tolerance and dependency that opioids can cause. To date, of all the 700 cone snail species, only six have been scrutinized in detail, and of the potentially thousands of unique compounds they harbour, only 100 have been studied in detail. Coral reefs and all their occupants are being destroyed at alarming rates.

Providing chemical compounds is not the only way biodiversity is crucial to our health. A surprising array of species have helped revolutionize medical knowledge. Zebrafish have been central to our knowledge of how organs, especially the heart, form; a microscopic roundworm has led to an understanding of ‘programmed cell death’ (apoptosis) which not only regulates organ growth, but which, when disrupted, can cause cancer. Fruit flies and bacterial species were principal contributors to research that mapped the human genome.

There may be undiscovered species which, like scientific laboratory animals, possess attributes rendering them particularly well suited for studying and treating human disease. Should these species be lost, their secrets will be lost with them.

What’s driving biodiversity loss?

The main factor currently driving biodiversity loss is habitat destruction—on land; in streams, rivers, and lakes; and in the oceans.

Unless we significantly reduce our use of fossil fuels, climate change alone is anticipated to threaten with extinction approximately one quarter or more of all species on land by the year 2050, surpassing even habitat loss as the biggest threat to life on land.

Species in the oceans and in fresh water are also at great risk from climate change, especially those like corals that live in ecosystems uniquely sensitive to warming temperatures, but the full extent of that risk has not yet been calculated.

Healthy planet, healthy humans


Losses to biodiversity impinge on human health in numerous ways. Ecosystem disruption and the loss of biodiversity have major impacts on the emergence, transmission, and spread of many human infectious diseases. The pathogens for 60 per cent of human infectious diseases, for example malaria and COVID, are zoonotic, meaning they have entered our bodies after having lived in other animals.

The virus that causes HIV/AIDS, and which has killed over 40 million people to date, likely made the species jump from chimpanzees butchered for bushmeat in West Central Africa. All in all, there may be 10,000 zoonotic viruses capable of jumping species to us circulating silently in the wild today.

This makes the One Health approach - a collaborative, multisectoral, and transdisciplinary approach that brings together various intergovernmental agencies, governments and local and regional actors to tackle human health and environmental health together - critical to minimizing the risk of future disease spillover.

Selfishly, if the natural world is healthy, we will be too.

Planetary life insurance

A key challenge for organizations working to preserve biodiversity is to convince others – policymakers and the public in particular – that human beings and our health are fundamentally reliant on the animals, plants, and microbes we share this small planet with. We are totally dependent on the goods and services the natural world provides, and we have no other choice but to preserve it.

The World Economic Forum estimates that half of the world’s GDP ($44 trillion) depends on nature. Globally, the pharmaceutical industry’s annual revenue is $1.27 trillion, and each year healthcare in the US alone costs over $4 trillion.

In comparison, the amount of money needed to close the finance gap to conserve biodiversity is only $700 billion a year. For planetary health and life insurance, that figure is not just a bargain, it’s a necessity.

Humans cannot exist outside of nature. Protecting the plants, animals, and microbes we share our small planet with is not voluntary, for it is these organisms that create the support systems that make all life on Earth, including human life, possible.
