With the global demand for sand and gravel standing at 40 to 50 billion tonnes per year, a new report by UN Environment reveals that aggregate extraction in rivers has led to pollution, flooding, lowering of water aquifers and worsening drought occurrence.
Sand extraction is fast becoming a transboundary issue due to sand extraction bans, international sourcing of sand for land reclamation projects and impacts of uncontrolled sand extraction beyond national borders. International trade in sand and gravel is growing due to high demand in regions without local sand and gravel resources and is forecast to rise 5.5 per cent a year with urbanization and infrastructure development trends.
Unsustainable sand extraction does not only impact the environment but can also have far-reaching social implications. Sand removal from beaches can jeopardize the development of the local tourism industry, while removing sand from rivers and mangrove forests leads to a decrease of crab populations—negatively affecting women whose livelihood depends on the collection of crabs.

In 2018 America imposed sanctions on about 1,500 people, firms, vessels and other entities, nearly triple the number in 2016. The past six months of 2019 have been particularly eventful. America began imposing sanctions on Iran in November, and in January on Venezuela, another big oil exporter. On May 9th 2019, for the first time, it seized a ship accused of transporting banned North Korean coal.
Second, blackballed countries and unscrupulous middlemen are getting better at evasion. In March 2019advisers to the un, relying in part on Windward data, and American Treasury officials published separate reports that described common ways of doing it. Boats turn off their transmissions systems to avoid detection. Oil is transferred from one ship to another in the middle of the ocean—ships trading on behalf of North Korea find each other in the East China Sea using WeChat, a popular Chinese messaging service. Captains disguise a ship’s identity by manipulating transponder data to transmit false locations and identity numbers of different vessels.
Such methods have helped Iran and Russia transport oil to Syria, American officials say. In 2018 North Korea managed to import refined petroleum far in excess of the level allowed by multilateral sanctions. The situation in Venezuela is different—technically, America’s sanctions still allow foreigners to do business with the country. But fear that sanctions will expand mean that traditional trading partners are scarce. Nicolás Maduro’s regime this month found a shipowner to transport crude to India, according to a shipbroker familiar with the deal, but Venezuela had to pay twice the going rate.
Businesses keen to understand such shenanigans can be roughly divided into two categories. The first includes those who can profit from grasping sanctions’ impact on energy markets, such as hedge funds, analysts and traders. A squadron of firms is ready to assist them, combing through ship transmission data, commercial satellite imagery and other public and semi-public information. They do not specialise in sanctions, but sanctions are boosting demand for their tracking and data-crunching expertise.
A main determinant of Venezuela’s output, for instance, is access to the diluent it needs to blend with its heavy crude. A firm called Clipper Data has noted Russian ships delivering diluent to vessels near Malta, which then transport it to Venezuela. Kpler, a French rival, uses satellite images of shadows on lids of storage tanks to help estimate the volume of oil inside. Using transmissions data, images, port records and more, Kpler produces estimates of Iran’s exports for customers such as the International Energy Agency and Bernstein, a research firm—including a recent uptick in Iranian exports without a specific destination (see chart).
The second category of companies are wary of violating sanctions themselves. They need assistance of a different sort. Latham & Watkins, a firm that advised the chairman of EN+, which controls a Russian aluminium giant, as he successfully removed the company from America’s sanctions list this year, has seen a surge in sanctions-related business. Refinitiv, a data company, offers software which permits clients to screen partners and customers against lists of embargoed entities. Windward uses machine learning to pore over data such as ships’ travel patterns, transmissions gaps (some of which may be legitimate) and name changes to help firms identify suspicious activity. Kharon, founded last year by former United States Treasury officials, offers detailed analysis of anyone or anything on sanctions lists.

The Bravo test, the testiong of a nuclear bomb on March 1, 1954, in the Bikini Atoll of the Marshall Islands resulted in an explosion that was 2½ times larger than expected. Radioactive ash dropped more than 7,000 square miles from the bomb site, caking the nearby inhabited islands. “Within hours, the atoll was covered with a fine, white, powder-like substance,” the Marshall Islands health minister would later testify, according to the Atomic Heritage Foundation. “No one knew it was radioactive fallout. The children played in the ‘snow.’ They ate it.”
The 1954 explosion was part of nuclear tests conducted as the American military lurched into the nuclear age. From 1946 o 1958, 67 U.S. nuclear tests were conducted in the Marshall islands….From 1977 to 1980, loose waste and top soil debris scraped off from six different islands in the Enewetak Atoll was transported to Runit island and was mixed with concrete and buried in nuclear blast crater. 4,000 US servicemen were involved in the cleanup that took three years to complete. The waste-filled crater was finally entombed in concrete. The Runit Dome, also called locally “The Tomb”, is a 46 cm (18 in) thick dome of concrete at sea level, encapsulating an estimated 73,000 m3 (95,000 cu yd) of radioactive debris, including some plutonium-239. …The structure, however, was never meant to last. Today, due to disrepair and rising sea tides, it is dangerously vulnerable. A strong storm could breach the dome, releasing the deadly legacy of America’s nuclear might….
Cracks have reportedly started to appear in the dome. Part of the threat is that the crater was never properly lined, meaning that rising seawater could breach the structural integrity. “The bottom of the dome is just what was left behind by the nuclear weapons explosion,” Michael Gerrard, the chair of Columbia University’s Earth Institute, told the ABC. “It’s permeable soil. There was no effort to line it. And therefore, the seawater is inside the dome.
According to Guterres, UN Secretary General, who refers to Runit Dome as nuclear coffin: The Pacific was victimized in the past as we all know, The consequences of these have been quite dramatic, in relation to health, in relation to the poisoning of waters in some areas.”

Radioactive carbon released into the atmosphere from 20th-century nuclear bomb tests has reached the deepest parts of the ocean, new research finds. A new study in AGU’s journal Geophysical Research Letters finds the first evidence of radioactive carbon from nuclear bomb tests in muscle tissues of crustaceans that inhabit Earth’s ocean trenches, including the Mariana Trench, home to the deepest spot in the ocean.
Organisms at the ocean surface have incorporated this “bomb carbon” into the molecules that make up their bodies since the late 1950s. Crustaceans in deep ocean trenches are feeding on organic matter from these organisms when it falls to the ocean floor. The results show human pollution can quickly enter the food web and make its way to the deep ocean, according to the study’s authors.
According to researchers, water containing carbon-14 can take centuries to circulate throughout the ocean, but the food web drastically accelerated the process. “There’s a very strong interaction between the surface and the bottom, in terms of biologic systems, and human activities can affect the biosystems even down to 11,000 meters,” said Weidong Sun, a coauthor of the study, “so we need to be careful about our future behaviors.”

In Malawi, ritual human sacrifice is till practiced. Murders are not uncommon. Women and children are killed for their breasts and genitals. Albinos, who number no more than 10,000 in Malawi, are said to carry the most powerful magic and are thus most at risk. Albino body parts can cost tens of thousands of dollars. The Association for Persons with Albinism in Malawi (APAM) says it began documenting attacks in 2014 after a surge before an election that year. Since then it has recorded 25 murders, 15 disappearances and 122 other crimes, including attempted abductions and exhumations.
In 2019, as Malawians prepare to vote in a general election on May 21st, there has been another rise in attacks. An albino man was killed and dismembered in front of his nine-year-old son. Three weeks later an 18-month-old girl was kidnapped. In February, a machete-wielding gang carried away Goodson Makanjira, aged 14. Another 11 attempted attacks were thwarted by neighbours, AAPM says. Activists suspect politicians are involved. Though evidence remains circumstantial, suspicions have been fuelled by the mysterious deaths (one in police custody) of two suspects who may have held clues about who is behind recent attacks…The scandal has only deepened since, with the parties of Mr Mutharika and his two chief rivals blaming each other for the killings. Mr Kalindo says that, while in custody earlier this year for insulting the president in song, he met suspects held for the murder of an albino in 2014. Lurid recordings of the men purportedly implicating one of the president’s senior advisers have been circulated widely on social media….Malawi’s albinos would rather their politicians stopped trading accusations and worked together to protect them…
Kenya has an albino senator and holds albino beauty pageants, which helps demystify the condition. Tanzania has created an island refuge for albinos.

The Trump administration is asking Congress for money to resume work on the Yucca Mountain nulcear waste storage in Nevada. But that may not end local opposition or a longstanding political stalemate. And in the meantime, nuclear plants are running out of room to store spent fuel….As the waste piles up, private companies are stepping in with their own solutions for the nation’s radioactive spent fuel. One is proposing a temporary storage site in New Mexico, and another is seeking a license for a site in Texas.
Most experts agree that what’s needed is a permanent site, like Yucca Mountain, that doesn’t require humans to manage it. “Institutions go away,” says Edwin Lyman, acting director of the Nuclear Safety Project at the Union of Concerned Scientists. “There’s no guarantee the owner will still be around for the duration of time when that waste remains dangerous, which is tens or hundreds of thousands of years.”
A California company says it has a viable plan for permanent storage. Deep Isolation wants to store spent fuel in holes drilled at least 1,000 feet underground in stable rock formations. The company says the waste would be separate from groundwater and in a place where it can’t hurt people. “I like to imagine having a playground at the top of the Deep Isolation bore hole where my kids and I can go play,” says CEO Elizabeth Muller. In November 2018, Muller’s company conducted a test north of Austin, Texas. Crews lowered an 80-pound canister into a drilled hole. It was a simulation, so no radioactive substances were involved. The goal was to determine whether they could also retrieve the canister. The test was successful, and that’s important. Regulators require retrieval, because new technology could develop to better deal with the spent fuel. And the public is less likely to accept disposal programs that can’t be reversed, according to the International Atomic Energy Agency.
Proving the waste can be retrieved may be the easy part. The bigger challenge is federal law, which doesn’t allow private companies to permanently store nuclear waste from power plants. Current law also says all the waste should end up at Yucca Mountain in Nevada. By contrast, Deep Isolation’s technology would store waste at sites around the country, likely near existing nuclear power plants.

A new front has opened in the battle between the U.S. and China over control of global networks that deliver the internet. This one is beneath the ocean. While the U.S. wages a high-profile campaign to exclude China’s Huawei Technologies Co. from next-generation mobile networks over fears of espionage, the company is embedding itself into undersea cable networks that ferry nearly all of the world’s internet data.
About 380 active submarine cables—bundles of fiber-optic lines that travel oceans on the seabed—carry about 95% of intercontinental voice and data traffic, making them critical for the economies and national security of most countries.
The Huawei Marine’s Undersea Cable Network majority owned by Huawei Technologies, has worked on some 90 projects to build or upgrade submarine cables around the world…US o fficials say the company’s knowledge of and access to undersea cables could allow China to attach devices that divert or monitor data traffic—or, in a conflict, to sever links to entire nations. Such interference could be done remotely, via Huawei network management software and other equipment at coastal landing stations, where submarine cables join land-based networks, these officials say.
Huawei Marine said in an email that no customer, industry player or government has directly raised security concerns about its products and operations.Joe Kelly, a Huawei spokesman, said the company is privately owned and has never been asked by any government to do anything that would jeopardize its customers or business. “If asked to do so,” he said, “we would refuse.”
The U.S. has sought to block Huawei from its own telecom infrastructure, including undersea cables, since at least 2012. American concerns about subsea links have since deepened—and spread to allies—as China moves to erode U.S. dominance of the world’s internet infrastructure…..Undersea cables are owned mainly by telecom operators and, in recent years, by such content providers as Facebook and Google. Smaller players rent bandwidth.Most users can’t control which cable systems carry their data between continents. A handful of switches typically route traffic along the path considered best, based on available capacity and agreements between cable operators.
In June 2017, Nick Warner, then head of Australia’s Secret Intelligence Service, traveled to the Solomon Islands, a strategically located South Pacific archipelago. His mission, according to people familiar with the visit, was to block a 2016 deal with Huawei Marine to build a 2,500-mile cable connecting Sydney to the Solomons. Mr. Warner told the Solomons’ prime minister the deal would give China a connection to Australia’s internet grid through a Sydney landing point, creating a cyber risk, these people said. Australia later announced it would finance the cable link and steered the contract to an Australian company. In another recent clash, the U.S., Australia and Japan tried unsuccessfully in September 2018 to quash an undersea-cable deal between Huawei Marine and Papua New Guinea.
U.S. and allied officials point to China’s record of cyber intrusions, growing Communist Party influence inside Chinese firms and a recent Chinese law requiring companies to assist intelligence operations. Landing stations are more exposed in poorer countries where cyber defenses tend to be weakest, U.S. and allied officials said. And network management systems are generally operated using computer servers at risk of cyber intrusion. Undersea cables are vulnerable, officials said, because large segments lie in international waters, where physical tampering can go undetected. At least one U.S. submarine can hack into seabed cables, defense experts said. In 2013, former National Security Agency contractor Edward Snowden alleged that Britain and the U.S. monitored submarine cable data. The U.S. and its allies now fear such tactics could be used against them. American and British military commanders warned recently that Russian submarines were operating near undersea cables. In 2018, the U.S. sanctioned a Russian company for supplying Russian spies with diving equipment to help tap seabed cables.
China seeks to build a Digital Silk Road, including undersea cables, terrestrial and satellite links, as part of its Belt and Road plan to finance a new global infrastructure network. Chinese government strategy papers on the Digital Silk Road cite the importance of undersea cables, as well as Huawei’s role in them. A research institute attached to China’s Ministry of Industry and Information Technology, in a paper published in September, praised Huawei’s technical prowess in undersea cable transmission and said China was poised to become “one of the world’s most important international submarine cable communication centers within a decade or two.” China’s foreign and technology ministries didn’t respond to requests for comment…
Bjarni Thorvardarson, then chief executive of the cable’s Ireland-based operator, said U.S. authorities raised no objections until 2012, when a congressional report declared Huawei Technologies a national security threat. Mr. Thorvardarson wasn’t convinced. “It was camouflaged as a security risk, but it was mostly about a preference for using U.S. technology,” he said. Under pressure, Mr. Thorvardarson dropped Huawei Marine from Project Express in 2013. The older cable network continued to use Huawei equipment.
The company is now the fourth-biggest player in an industry long dominated by U.S.-based SubCom and Finnish-owned Alcatel Submarine Networks. Japan’s NEC Corp is in third place.Huawei Marine is expected to complete 28 cables between 2015 and 2020—nearly a quarter of all those built globally—and it has upgraded many more, according to TeleGeography, a research company.
