Scientists Call for Cheetahs to Be Listed as Endangered
A year ago, scientists reported that cheetahs had disappeared from across 91 percent of their historic range.
The cheetah (Acinonyx jubatus), the researchers recommended in their study, should be up-listed from Vulnerable to Endangered on the IUCN Red List of Threatened Species. Doing this could afford the imperiled species greater attention and support, they said.
The cheetah, however, remains officially listed as Vulnerable on the IUCN Red List.
Now, in a new study, scientists have called for up-listing the species to Endangered yet again.
By analyzing millions of cheetah observations, a team of researchers have concluded that only about 3,577 adult cheetahs remain in southern Africa–within an area of 789,800 square kilometers across Namibia, Botswana, South Africa and Zimbabwe. More than 55 percent of these cheetahs live in Namibia alone, the researchers reported in the study published in the journal PeerJ.
"This is the area with the largest population of free-ranging cheetahs left on Earth," lead author of the study Varsha Vijay of Duke University said in a statement. "Knowing how many cheetahs there are and where they occur is crucial for developing suitable conservation management plans for the species."
The researchers also estimate that there could be an additional 3,250 cheetahs living in potential habitat areas, or places where cheetahs can possibly live but where they have not been observed recently. But the team has lower confidence in this estimate. "We know about three and a half thousand cheetahs. There could be twice as many, but we can't prove it," Florian Weise of the U.S.-based conservation group Claws Conservancy, also a lead author of the study, told National Geographic news.

Of the 3,577 known cheetahs, less than 50 percent live inside some form of protected area, such as Kruger National Park in South Africa, the study estimates. The rest live on unprotected lands, mostly allocated for livestock or game production. Many farmers who share their land with cheetahs, consider the animals to be a source of conflict, the researchers found. While only a few resort to actually killing or trapping the animals, the researchers say that persecution by even a few farmers can cause cheetah populations to decline.
"The future of the cheetah relies heavily on working with farmers who host these big cats on their lands, bearing the heaviest cost of coexistence," said Weise.
Given that the study's population estimate for the cheetah is 11 percent lower than the IUCN's current assessment for the same region, the authors write that the species should be urgently up-listed from Vulnerable to Endangered status. This revision of status could help conservationists create more awareness about the species and "open more avenues to fund conservation and population monitoring efforts," they said in the statement. This study was supported by the National Geographic Society's Big Cats Initiative.

More long-finned pilot whales were found stranded today on beaches in Tasmania, Australia. About 500 whales have become stranded, including at least 380 that have died, the AP reported. It is the largest mass stranding in Australia's recorded history.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.

Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
