Increasingly sophisticated technology that detects nuances in sound inaudible to humans is capturing clues about people’s likely locations, medical conditions and even physical features.Law-enforcement agencies are turning to those clues from the human voice to help sketch the faces of suspects. Banks are using them to catch scammers trying to imitate their customers on the phone, and doctors are using such data to detect the onset of dementia or depression. That has… raised fresh privacy concerns, as consumers’ biometric data is harnessed in novel ways.
“People have known that voice carries information for centuries,” said Rita Singh, a voice and machine-learning researcher at Carnegie Mellon University who receives funding from the Department of Homeland Security…Ms. Singh measures dozens of voice-quality features—such as raspiness or tremor—that relate to the inside of a person’s vocal tract and how an individual voice is produced. She detects so-called microvolumes of air that help create the sound waves that make up the human voice. The way they resonate in the vocal tract, along with other voice characteristics, provides clues on a person’s skull structure, height, weight and physical surroundings, she said.
Nuance’s voice-biometric and recognition software is designed to detect the gender, age and linguistic background of callers and whether a voice is synthetic or recorded. It helped one bank determine that a single person was responsible for tens of millions of dollars of theft, or 18% of the fraud the firm encountered in a year, said Brett Beranek, general manager of Nuance’s security and biometrics business.
Audio data from customer-service calls is also combined with information on how consumers typically interact with mobile apps and devices, said Howard Edelstein, chairman of behavioral biometric company Biocatch. The company can detect the cadence and pressure of swipes and taps on a smartphone. How a person holds a smartphone gives clues about their age, for example, allowing a financial firm to compare the age of the normal account user to the age of the caller…
If such data collected by a company were improperly sold or hacked, some fear recovering from identity theft could be even harder because physical features are innate and irreplaceable.

In August 2019, Tepco projected that storage of radioactive water at the Fukushima nuclear plant would reach full capacity by around summer 2022 even after the expansion — the first time it has issued such a precise estimate. According to Tepco, the Fukushima No. 1 plant had 960 massive tanks containing 1.15 million tons of treated water as of July 18, 2019. Water that has touched the highly radioactive melted fuel debris has been cleaned up through water treatment machines and is stored in the tanks, but the high-tech treatment machines are able to remove most radionuclides except tritium. The plant currently sees an increase of contaminated water by 170 tons a day, Tepco says.
Releasing tritium-tainted water into the sea in a controlled manner is common practice at nuclear power plants around the world, and it was generally considered the most viable option as it could be done quickly and would cost the least. The head of the Nuclear Regulation Authority, Toyoshi Fuketa, has long said that releasing the treated water into the sea is the most reasonable option, but people in Fukushima, especially fishermen, fear it will damage the region’s reputation.
Addressing those concerns, the government panel, launched in November 2016, has been looking for the best option in terms of guarding against reputational damage. Injecting it into the ground, discharging it as steam or hydrogen, or solidification followed by underground burial have all been on the table. Under the current plan, Tepco is set to increase the tank space to store 1.37 million tons of water a total, but estimates show that will only last until summer 2022. But the more space it creates, the bigger the decommissioning headache becomes.

A snail that lives near hydrothermal vents on the ocean floor east of Madagascar has become the first deep-sea animal to be declared endangered because of the threat of mining. The International Union for Conservation of Nature (IUCN) added the scaly-foot snail (Chrysomallon squamiferum) to its Red List of endangered species on 18 July, 2019 — amid a rush of companies applying for exploratory mining licenses…. The scaly-foot snail is found at only three hydrothermal vents in the Indian Ocean. Two of those three vents are currently under mining exploration licences,…Even one exploratory mining foray into this habitat could destroy a population of these snails by damaging the vents or smothering the animals under clouds of sediment..
Full-scale mining of the deep seabed can’t begin in international waters until the International Seabed Authority (ISA) — a United Nations agency tasked with regulating sea-bed mining — finalizes a code of conduct, which it hopes to do by 2020….The biggest challenge to determining whether the scaly-foot snail warranted inclusion on the Red List was figuring out how to assess the extinction risk for animals that live in one of the weirdest habitats on Earth…
When the IUCN considers whether to include an organism on the Red List, researchers examine several factors that could contribute to its extinction. They include the size of a species’ range and how fragmented its habitat is…The IUCN settled on two criteria to assess the extinction risk for deep-sea species: the number of vents where they’re found, and the threat of mining. In addition to the scaly-foot snail, the researchers are assessing at least 14 more hydrothermal vent species for possible inclusion on the Red List.

Functional splintering [of the internet] is already happening. When tech companies build “walled gardens”, they decide the rules for what happens inside the walls, and users outside the network are excluded…
Governments are playing catch-up but they will eventually reclaim the regulatory power that has slipped from their grasp. Dictatorships such as China retained control from the start; others, including Russia, are following Beijing. With democracies, too, asserting their jurisdiction over the digital economy, a fragmentation of the internet along national lines is more likely. …The prospect of a “splinternet” has not been lost on governments. To avoid it, Japan’s G20 presidency has pushed for a shared approach to internet governance. In January 2019, prime minister Shinzo Abe called for “data free flow with trust”. The 2019 Osaka summit pledged international co-operation to “encourage the interoperability of different frameworks”.
But Europe is most in the crosshairs of those who warn against fragmentation…US tech giants have not appreciated EU authorities challenging their business model through privacy laws or competition rulings. But more objective commentators, too, fear the EU may cut itself off from the global digital economy. The critics fail to recognise that fragmentation can be the best outcome if values and tastes fundamentally differ…
If Europeans collectively do not want micro-targeted advertising, or artificial intelligence-powered behaviour manipulation, or excessive data collection, then the absence on a European internet of services using such techniques is a gain, not a loss. The price could be to miss out on some services available elsewhere… More probably, non-EU providers will eventually find a way to charge EU users in lieu of monetising their data…Some fear EU rules make it hard to collect the big data sets needed for AI training. But the same point applies. EU consumers may not want AI trained to do intrusive things. In any case, Europe is a big enough market to generate stripped, non-personal data needed for dumber but more tolerable AI, though this may require more harmonised within-EU digital governance. Indeed, even if stricter EU rules splinter the global internet, they also create incentives for more investment into EU-tailored digital products. In the absence of global regulatory agreements, that is a good second best for Europe to aim for.

A competition for the North Pole heated up in May 2019, as Canada became the third country to claim—based on extensive scientific data—that it should have sovereignty over a large swath of the Arctic Ocean, including the pole. Canada’s bid, submitted to the United Nations’s Commission on the Limits of the Continental Shelf (CLCS), joins competing claims from Russia and Denmark. Like theirs, it is motivated by the prospect of mineral riches: the large oil reserves believed to lie under the Arctic Ocean, which will become more accessible as the polar ice retreats. And all three claims, along with dozens of similar claims in other oceans, rest on extensive seafloor mapping, which has proved to be a boon to science…
Coastal nations have sovereign rights over an exclusive economic zone (EEZ), extending by definition 200 nautical miles (370 kilometers) out from their coastline. But the 1982 United Nations Convention on the Law of the Sea opened up the possibility of expanding that zone if a country can convince CLCS that its continental shelf extends beyond the EEZ’s limits…..Most of the 84 submissions so far were driven by the prospect of oil and gas, although advances in deep-sea mining technology have added new reasons to apply. Brazil, for example, filed an application in December 2018 that included the Rio Grande Rise, a deep-ocean mountain range 1500 kilometers southeast of Rio De Janeiro that’s covered in cobalt-rich ferromanganese crusts.
To make a claim, a country has to submit detailed data on the shape of the sea floor and on its sediment, which is thicker on the shelf than in the deep ocean. …CLCS, composed of 21 scientists in fields such as geology and hydrography who are elected by member states, has accepted 24 of the 28 claims it has finished evaluating, some partially or with caveats; in several cases, it has asked for follow-up submissions with more data. Australia was the first country to succeed, adding 2.5 million square kilometers to its territory in 2008. New Zealand gained undersea territory six times larger than its terrestrial area. But CLCS only judges the merit of each individual scientific claim; it has no authority to decide boundaries when claims overlap. To do that, countries have to turn to diplomatic channels once the science is settled.
The three claims on the North Pole revolve around the Lomonosov Ridge, an underwater mountain system that runs from Ellesmere Island in Canada’s Qikiqtaaluk region to the New Siberian Islands of Russia, passing the North Pole. Both countries claim the ridge is geologically connected to their continent, whereas Denmark says it is also tied to Greenland, a Danish territory. As the ridge is thought to be continental crust, the territorial extensions could be extensive)
Tensions flared when Russia planted a titanium flag on the sea floor beneath the North Pole in 2007, after CLCS rejected its first claim, saying more data were needed. The Canadian foreign minister at the time likened the move to the land grabs of early European colonizers. Not that the North Pole has any material value: “The oil potential there is zip,” says geologist Henry Dick of the Woods Hole Oceanographic Institution in Massachusetts. “The real fight is over the Amerasian Basin” where large amounts of oil are thought to be locked up…
There’s also a proposal to makethe North Pole international, like Antarctica (South Pole), as a sign of peace, says Oran Young, a political scientist at the University of California, Santa Barbara. “It seems a very sensible idea.”

Agriculture continues to present the biggest threat to forests worldwide. Some experts predict that crop production needs to be doubled by 2050 to feed the world at the current pace of population growth and dietary changes toward higher meat and dairy consumption. Scientists generally agree that productivity increase alone is not going to do the trick. Cropland expansion will be needed, most likely at the expense of large swathes of tropical forests – as much as 200 million hectares by some estimates.
Nowhere is this competition for land between forests and agriculture more acute than in Africa. Its deforestation rate has surpassed those of Latin America and Southeast Asia. Sadly, the pace shows no sign of slowing down. Africa’s agriculture sector needs to feed its burgeoning populations- the fastest growing in the world…. What’s more, for the millions of unemployed African youth, a vibrant agriculture sector will deliver jobs and spur structural transformation of the rural economy. Taken together, the pressures on forests are immense. Unless interventions are made urgently, a large portion of Africa’s forests will be lost in the coming decades – one farm plot at a time.
The difficult question is: what interventions can protect forests and support farmers at the same time?
To tackle these complex challenges, the Center for International Forestry Research (CIFOR) has launched a new initiative: The “Governing Multifunctional Landscapes (GML) in Sub-Saharan Africa: Managing Trade-Offs Between Social and Ecological Impacts” Read more

The instinctive response of many environmentalists is to to fence off protected areas as rapidly and extensively as possible. That thought certainly dominates discussions of the Convention on Biological Diversity, the main relevant international treaty. An eight-year-old addendum to the pact calls for 17% of the world’s land surface and 10% of the ocean’s water column (that is, the water under 10% of the ocean’s surface) to be protected by 2020. Currently, those figures are 15% and 6%. Campaigners want the next set of targets, now under discussion, to aim for 30% by 2030—and even 50% by 2050. This last goal, biogeographers estimate, would preserve 85% of life’s richness in the long run. As rallying cries go, “Nature needs half” has a ring to it, but not one that sounds so tuneful in the poor countries where much of the rhetorically required half will have to be found. Many people in such places already feel “Cornered by Protected Areas.” (See also Biodiversity and Human Rights)
James Watson, chief scientist at the Wildlife Conservation Society (wcs), another American charity, has an additional worry about focusing on the fence-it-off approach. If you care about the presence of species rather than the absence of humans, he warns, “‘nature needs half’ could be a catastrophe—if you get the wrong half.” Many terrestrial protected areas are places that are mountainous or desert or both. Expanding them may not translate into saving more species. Moreover, in 2009 Lucas Joppa and Alexander Pfaff, both then at Duke University in North Carolina, showed that protected areas disproportionately occupy land that could well be fine even had it been left unprotected: agriculture-unfriendly slopes, areas remote from transport links or human settlements, and so on. Cordoning off more such places may have little practical effect.
In the United States it is the underprotected southern Appalachians, in the south-east of the country, that harbour the main biodiversity hotspots. The largest patches of ring-fenced wilderness, however, sit in the spectacular but barren mountain ranges of the west and north-west. In Brazil, the world’s most speciose country, the principal hotspots are not, as might naively be assumed, in the vast expanse of the Amazon basin, but rather in the few remaining patches of Atlantic rainforest that hug the south-eastern coast.
Nor is speciosity the only consideration. So is risk-spreading. A team from the University of Queensland, in Australia, led by Ove Hoegh-Guldberg, has used a piece of financial mathematics called modern portfolio theory to select 50 coral reefs around the world as suitable, collectively, for preservation. Just as asset managers pick uncorrelated stocks and bonds in order to spread risk, Dr Hoegh-Guldberg and his colleagues picked reefs that have different exposures to rising water temperatures, wave damage from cyclones and so on. The resulting portfolio includes reefs in northern Sumatra and the southern Red Sea that have not previously registered on conservationists’ radar screens…
Another common finding—counterintuitive to those who take the “fence-it-all-off” approach—is that a mixed economy of conservation and exploitation can work. For example, rates of deforestation in a partly protected region of Peru, the Alto Mayo, declined by 78% between 2011 and 2017, even as coffee production increased from 20 tonnes a year to 500 tonnes.
Environmental groups can also draw on a growing body of academic research into the effective stewardship of particular species. For too long, says William Sutherland, of Cambridge University, conservationists have relied on gut feelings. Fed up with his fellow practitioners’ confident but unsubstantiated claims about their methods, and inspired by the idea of “evidence-based medicine”, he launched, in 2004, an online repository of relevant peer-reviewed literature called Conservation Evidence. Today this repository contains more than 5,400 summaries of documented interventions. These are rated for effectiveness, certainty and harms. Want to conserve bird life threatened by farming, for example? The repository lists 27 interventions, ranging from leaving a mixture of seed for wild birds to peck (highly beneficial, based on 41 studies of various species in different countries) to marking bird nests during harvest (likely to be harmful or ineffective, based on a single study of lapwing in the Netherlands). The book version of their compendium, “What Works in Conservation”, runs to 662 pages. It has been downloaded 35,000 times.
