29 Jul 2015: Global Population Projected to
Reach 11 Billion by 2100, U.N. Estimates

The current world population of 7.3 billion is expected to reach 8.5 billion by 2030, 9.7 billion by 2050, and 11.2 billion in 2100,

according to a United Nations report released today. The revised U.N. estimates counter previous projections, which had said that global population would peak at roughly 9 billion by 2050, then gradually decline. Most growth will occur in developing regions, the new report says, especially Africa, which is expected to account for more than half of the world’s population growth between 2015 and 2050. India is expected to become the most populous country, surpassing China around 2022. Nigeria could surpass the United States by 2050, which would make it the third-largest country in the world, the United Nations projects.

The Church of England's investment fund is valued at roughly $10.5 billion, and $2.5 million of that had been invested in Soco International. The move marks only the third time in recent years that the church has divested from a company on ethical grounds. In 2012 it sold its holdings in News Corporation to protest the phone-hacking scandal, and in 2010 it divested from a mining corporation over human rights violations associated with its operations in India.

Canine Conservation: Using Dogs
In War Against Poachers in Kenya


In Kenya’s Ol Pejeta Conservancy — home to some of the most endangered subspecies of rhinoceros — officials are deploying a new weapon to combat rampant rhino poaching: highly trained K-9 dogs. Six Belgian Malinois tracking and attack dogs are now working with Kenyan rangers to protect tiny populations of northern white rhinos and eastern black rhinos, which have been hunted to near-extinction by poachers seeking rhino horn for supposed medicinal purposes. Overseen by a former military dog instructor with the U.K. Royal Army Veterinary Corps, the K-9 units are being deployed not only in Ol Pejeta but also in a Tanzanian park that has been plagued by poaching.

28 Jan 2015: Camera Trap Records Rare
Glimpse of African Golden Cat Hunting

An African golden cat, one of the least known and most elusive wild cats on the planet, has been filmed hunting in

Kibale National Park, Uganda, for the first time, scientists say. In the video, which was recorded by a camera trap, an African golden cat darts toward a group of red colobus monkeys feeding on a tree stump. The cat's attack is nearly too fast to be seen in real-time, but viewing the footage in slow-motion highlights the cat's swiftness and accuracy — even though its ambush failed to land a meal. The African golden cat is found only in the forests of central and West Africa, and it is threatened across its range by intensive bushmeat hunting and habitat loss. Researchers say the video provides important details about the African golden cats' hunting behavior that have never before been directly observed.

27 Jan 2015: Pollinator Loss Could Put
Poor Nations at Risk for Malnutrition

Declining pollinator populations could leave as many as half of the people in developing countries facing nutritional deficiencies, according to researchers from the University of Vermont and the Harvard School of Public Health. In the study — the first to link pollinator declines directly to human nutrition — researchers collected detailed data about people's daily diets in parts of Zambia, Mozambique, Uganda, and Bangladesh. They found that in Mozambique, for example, many children and mothers are barely able to meet their needs for micronutrients, especially vitamin A, which is important for preventing blindness and infectious diseases. Fruits and vegetables were an important source of that nutrient for many people in the study, and those crops are highly dependent on pollinators, researchers say — for example, yields of mangoes, which are high in vitamin A, would likely be cut by 65 percent without them. Pollinator losses might also lead to folate deficiency, they say, which is associated with neural tube defects.

An additional 56 rhinos were moved from poaching hotspots within South Africa's Kruger National Park — where two-thirds of the killings happen — to an "intensive protection zone" within Kruger, officials said. Poachers killed a record number of the animals in South Africa last year — 1,215 rhinos, up 20 percent from the 2013 total — and 49 have been killed so far this year. The animals are hunted intensely because their horns, which some Asian cultures incorrectly believe contain medicinal properties, are worth an estimated $65,000 per kilogram on the black market.

blood from a local slaughterhouse into biogas that can power the facility as well as other local businesses, Reuters reports. The Keeko Biogas project plans to start bottling the fuel and selling cylinders of it in March, once safety testing has been completed, project leaders say. At roughly $8 per 6-kilogram cylinder, the biogas is about half the price of liquefied petroleum gas, and it can be up to 40 percent more energy efficient than propane or butane, says the Kenya Industrial Research and Development Institute, which is providing technical support for the project. The facility will be able to produce 100 to 300 cylinders of biogas per week, organizers say. The project will not only offset the costs of waste management for the slaughterhouse, it will also likely help prevent deforestation in the region. "We cut down a lot of trees for charcoal and we hope to reduce that,” the chairman of the slaughterhouse told Reuters.

surpasses last year’s record slaughter of 1,004 of the endangered animals. Poaching has been on the rise in South Africa, home to the world’s largest population of rhinos, since 2007, when only seven rhinos were killed. The sharp increase is occurring despite steps by the government to improve enforcement and introduce new technologies and intelligence-gathering methods to curb poaching, Mongabay reports. As of 2010, South Africa was home to more than 18,000 white rhinos — over 90 percent of the global population — and nearly 2,000 black rhinos. The animals are being killed for their horns, which are in high demand in China and Vietnam for their supposed, but unproven, medicinal qualities.

07 Nov 2014: Organized Chinese Crime Behind Tanzania's Elephant Slaughter, Report Says

Chinese-led criminal organizations have been conspiring with corrupt Tanzanian officials to traffic huge amounts

of ivory — a trade that has caused half of Tanzania’s elephants to be poached in the past five years — according to a report by the London-based Environmental Investigation Agency. In some cases, Chinese military officials appeared to be complicit in the illegal activities, the report says, and in other instances, prominent Tanzanian businessmen and politicians helped protect ivory traffickers. Tanzania is the largest source of poached ivory in the world, and China is the largest importer of smuggled tusks, according to EIA. Tanzania’s famed Selous Reserve saw its elephant population plunge by 67 percent in four years, from 50,000 animals to 13,000. Tanzania appears to have lost more elephants to poaching during this period than any other country, EIA said.

23 Sep 2014: Food Security Issues Often
Neglected After Extreme Weather Events

Extreme weather events — the sort likely to arise with increasing frequency as the planet warms — took a heavy toll on Russia and East Africa in 2010 and 2011, in large part because governments and authorities were ill-equipped to address resulting food shortages and other fallout, according to researchers at the University of Oxford. Russia experienced a heat wave that led to food hoarding and price-fixing of staple crops by speculators, according to the report, which was commissioned by Oxfam. A drought in East Africa in 2010 through 2011 was tied to an uptick in armed conflicts in the region, which interrupted international and domestic aid for six months. Crop prices reached record levels in several markets, including wheat in Ethiopia, maize in Kenya, and red sorghum grain in Somalia, the report notes. Investing in additional health facilities, establishing pre-positioned food supplies, and other tactics aimed at mitigating the effects of future heat waves, droughts, and floods, could help to blunt the effects of climate change on the poorest and most vulnerable populations, the researchers say.

people in the world, now 7.2 billion, will increase to between 9.6 and 12.3 billion in 2100. Published in the journal Science, the study counters the widely accepted projection that global population will peak at roughly 9 billion by 2050, then gradually decline. The new study instead finds a 70-percent likelihood that population will grow continuously throughout the century to reach 10.9 billion by 2100. Researchers attribute the higher projections, in part, to increasing fertility rates in sub-Saharan Africa, where population growth had been predicted to continue slowing. The Guardian notes that many widely cited global policy assessments, such as recommendations from the Intergovernmental Panel on Climate Change, assume a population peak by 2050.

03 Sep 2014: Mobile Phone Networks Can
Help Monitor Global Rainfall, Study Says

New research shows that mobile phone networks, which cover 90 percent of the world's population, can help track rainfall events — a task that has proven difficult for both advanced satellite systems and ground-level observation networks. By compiling data on signal disruptions from mobile phone networks in Burkina Faso in West Africa, a team of researchers was able to calculate with 95 percent accuracy both the location and volume of rain that fell, even during short-lived storms, according to a report in Geophysical Research Letters. Mobile phone companies maintain detailed records on signal disruptions, which can occur when water droplets block and deflect signals between antennae, to determine whether their networks are functioning properly. By tapping into those records, researchers could distill data on rainfall events at extremely fine spatial and temporal scales. As mobile phone networks expand across the globe, such data could be used to create highly accurate rainfall maps, researchers say, although gaining access to records could prove difficult.

The browning of Congo's rainforest is significant, researchers said, because most climate models forecast that tropical forests may face increasing stress and rainfall shortages in a warmer and drier 21st century. A continued drying trend might alter the composition and structure of the Congo rainforest, affecting its biodiversity and carbon storage, according to the study. "Recent climate anomalies as a result of climate change and warming of the Atlantic Ocean have created severe droughts in the tropics, causing major impacts on forests," a NASA researcher said.

attacks and retaliatory killings by more than 85 percent in the areas they've been installed, the Guardian reports. Traditionally, the Masai have built livestock enclosures out of thorny acacia trees, but those fences are relatively fragile. Chain-link fencing alone is more durable, but leopards and small lions can scale the fences, and hyenas can tunnel in below. By interweaving actively growing African myrrh trees with the chain link fencing, the Masai have created a barrier that lions can't climb over, and their root systems prevent predators from digging under the fence. Because livestock predation has been cut, communities that had been killing six or seven lions annually now kill, on average, less than one, leading to a rebound in lion populations.

The researchers first reported on this community in 2007, but their new survey includes detailed videos of the thriving population and its unique behaviors, which include feasting on leopards, using tools to harvest giant African snails and swarming insects, and building ground nests far more frequently than other chimps. While the find is heartening in terms of chimpanzee conservation, the researchers and wildlife advocates fear the population could be decimated by habitat loss and poachers, who stand to make huge profits in the bushmeat trade.

The maps also highlight which corridors are most important for sequestering carbon and averting carbon emissions associated with deforestation. Researchers hope the findings will help guide wildlife protection plans and serve as a framework prioritizing the conservation of habitat corridors.

world's 20,000 rhinos, which are targeted by poachers because their horns are highly valued and believed to contain medicinal properties. Although those claims are scientifically unfounded, demand from increasingly wealthy consumers in China and Vietnam has driven the price of rhino horns to over $65,000 per kilogram — more valuable than gold, platinum, or cocaine. South Africa has tried to stem the crisis by training park rangers to use arms, drones, and helicopters, but those anti-poaching efforts have shown limited success. Rhino poachings in 2012 also increased by 50 percent over 2011 totals, and 37 have been poached so far in 2014, officials report. Most of the killings are taking place in South Africa's Kruger National Park, where 606 rhinos were killed last year and 425 in 2012.

Of the remaining lions, only about 250 are mature enough to reproduce, but in many cases those individuals are spread too far apart to breed. West African lions are now present in only 1.1 percent of their original habitat and should be considered "critically endangered," according to the study. Running low on habitat and prey, the lions sometimes kill livestock. Villagers then kill the lions in revenge. "It's become very complicated for this carnivore at the top of the food chain to find enough space and food to survive," one scientist told Reuters.

deaths from poaching were officially reported in Africa and that another 7,000 deaths went unreported. Although that number is a slight decrease from the 2011 estimate of 25,000 poaching deaths, CITES officials warn that poaching rates are far too high and could soon lead to local extinctions. Africa, which is currently home to roughly 500,000 elephants, could lose a fifth of its elephant population over the next 10 years, CITES says. "The estimated poaching rate of 7.4 percent in 2012 remains at an unsustainably high level, as it exceeds natural population growth rates (usually no more than 5 percent)," the report says.

14 Nov 2013: U.S. Crushes Six Tons

The U.S. Fish and Wildlife Service (FWS) destroyed six tons of elephant ivory today that field agents seized over the past 25 years. The U.S. Ivory Crush event, which took place in Denver, Colorado, marked the first time the FWS has destroyed large quantities of ivory. The move was an attempt to send a clear message that the U.S. will not tolerate illegal ivory trafficking and the toll it's taking on elephant populations in Africa and Asia, the FWS said. Seized ivory is usually kept as evidence for prosecuting traffickers, then later used for education and training, but the FWS had accumulated far more ivory than it needs. The ivory that was crushed included full tusks, carved tusks, jewelry, carvings, and other objects, and came from at least 2,000 poached elephants, the FWS estimates.

such as drought are common, those events are the leading cause of poverty, the authors say, rather than poor health or societal factors. Across the globe, up to 325 million people will be living in countries that face natural hazard risks by 2030, the report says; in sub-Saharan Africa alone, 118 million people in poverty will face extreme events. To brace against the effects of disasters, aid money should be spent on reducing those risks, rather than only on humanitarian relief after an extreme event, the authors argue. Currently, money tends to flow to a region after a disaster instead of before, when it could be used for prevention. "If the international community are serious about ending extreme poverty, they need to get serious about reducing disaster risk for the poorest people," the institute's Tom Mitchell told the BBC.

The study found two species — the common slender mongoose and the Cameroon cusimanse — that hadn't been found in Gabon before, and it documented an extended range for the Egyptian mongoose. “It appears that these species are widespread and not currently threatened, but the proximity of many small carnivores to human settlements and the growing bushmeat trade could potentially impact these populations," said Wildlife Conservation Society researcher Fiona Maisels, who co-authored the study. "These new findings will help inform future management."

The Partnership to Save Africa's Elephants, which includes the governments of seven African nations, will fund programs that scale up anti-poaching enforcement, combat trafficking at ports and markets with more enforcement and harsher penalties, and curb the demand for illegal ivory with ad campaigns aimed at consumers in China, Vietnam, and other nations.

Park rangers arrested nine alleged poachers after following them to a cache of ivory tusks hidden in the park. The elephant death toll of 81 includes 41 carcasses found earlier this month following another cyanide poisoning incident in Hwange park. Zimbabwe's new environment minister, Saviour Kasukuwere, has pledged to make jail penalties for poachers harsher. Elephant and rhino poaching in Africa has accelerated in recent years due to increasing Asian demand for ivory and rhino horn, which is used in traditional medicines, even though it has no proven medicinal properties. Officials estimate tens of thousands of elephants are being slaughtered each year in the worst wave of poaching in decades.

Writing in the journal Nature, Malaysian and U.S. researchers describe the mapping of the genome of the oil palm, whose products are used in everything from food to cosmetics to biofuels. According to the scientists, the so-called “shell gene” controls “how the thickness of its shell correlates to fruit size and oil yield.” The fruit of the African palm oil tree comes in three varieties: a thick-shelled dura, a shell-less pisifera, and a thin-shelled tenera, which produces a greater oil yield. According to scientists, the shell gene plays a key role in a mutation that produces the more commercially productive tenera variety.

26 Jun 2013: Exposure to Lead Costs
Developing Nations $1 Trillion Annually

The exposure of children to toxic lead, and the subsequent declines in IQ and earning potential, costs the developing world nearly $1 trillion annually, according to a new report. Based on the average lead levels in children under the age of 5, researchers from New York University found that Africa suffers the greatest costs from lead exposure, losing an estimated $137.7 billion annually, or about 4 percent of its gross domestic product (GDP). In Latin America, the costs are about $142.3 billion, the study found, while in Asian nations the costs are about $699.9 billion. By comparison, the annual costs in the U.S. and Europe, where exposure to lead has decreased significantly in recent decades, are about $50 billion and $55 billion, respectively. The report said lead consumption has increased worldwide since the early 1970s, largely because of rising demand for lead batteries. The study was published in Environmental Health Perspectives.

avian populations worldwide. The U.S. Fish and Wildlife Service (FWS) reports that numbers of some migratory bird populations in Maine — including Arctic terns and puffins — have plummeted in recent years because their food supplies are disappearing as a result of commercial fishing and the shifting of fish to cooler waters, which is making it more difficult for some birds to feed their young. In a separate study, scientists predict that rising sea levels will devastate habitat for some migratory shore birds in the coming decades. Higher sea levels, the study predicts, will flood 23 percent to 40 percent of the intertidal habitats for several shorebird species, triggering population declines of as much as 70 percent. Overall, one in eight bird species globally is at risk of extinction, according to a new report by BirdLife International.
