Mountain Gorilla Population Surpasses 1,000, Despite Challenges
Numbers of critically endangered mountain gorillas are on the up, following conservation efforts in the transboundary Virunga Massif, one of the two remaining areas where the great ape is still found.
Survey results released Thursday reveal that numbers have increased to 604 from an estimated 480 in 2010, including 41 social groups, along with 14 solitary males in the transboundary area. This brings the global wild population of mountain gorillas to an estimated 1,004 when combined with published figures from Bwindi Impenetrable National Park (where the rest of the sub-species is found) and makes it the only great ape in the world that is considered to be increasing in population.
The findings are the result of intensive surveying coordinated by the Greater Virunga Transboundary Collaboration and supported by the International Gorilla Conservation Programme (IGCP—a coalition program of Fauna & Flora International (FFI) and World Wildlife Fund WWF) along with other partners.
Despite this good news, the survey found that direct threats from wire or rope snares persist. During the surveys, the teams found and destroyed more than 380 snares, which were set for antelope but can also kill or harm gorillas. One of the snares discovered by the teams contained a dead mountain gorilla. There are also new threats looming large on the horizon, including climate change, infrastructure development and the ever-present specter of disease, which has the potential to devastate the remaining populations.
Ongoing conflict and civil unrest in the region also present an ongoing risk, impacting people and wildlife. A number of rangers have been killed in recent weeks in the Democratic Republic of Congo's Virunga National Park.
"This is fabulous news for mountain gorillas and shows what we can do for wildlife when NGOs, governments and their communities work together," said Margaret Kinnaird, wildlife practice leader with WWF. "The mountain gorilla story can be a model for how to restore and maintain our earth's precious biodiversity," she added.
"Since FFI first began working to protect mountain gorillas in the 1970s, we have seen a remarkable transformation in the fortunes of this great ape, which at that time was on the very precipice of extinction," said Alison Mollon, director of operations for Africa at FFI. "This turnaround is thanks to the extraordinary efforts of all those who have persisted through immense challenges—sometimes even risking their own lives—to protect these great apes."
The census involved twelve teams—comprising people from more than 10 institutions—which covered more than 2,000 kilometers (approximately 1,243 miles) of difficult, forested terrain systematically searching the mountain gorilla habitat for signs of the animals, recording nest sites and collecting faeces samples for genetic analysis. The teams also looked for evidence of threats to gorillas and other wildlife.
Reacting to the news, FFI vice president and WWF-UK ambassador Sir David Attenborough said: "When I first visited the mountain gorillas in 1979, the situation was dire; the number of these remarkable animals was dreadfully small. It is incredibly heartening therefore to see how the efforts of so many different groups—communities, governments, NGOs—have paid off. The threats to mountain gorillas haven't disappeared entirely, of course, so now the challenge must be to ensure that these achievements are sustained long into the future."
The survey results underscore the need for continued attention and action by government agencies, protected area staff, tourism operators, tourists and communities alike, to ward off these threats and keep mountain gorillas safe in the long term.

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.
Sweden is a world leader in renewable energy consumption. Swedish Institute/World Bank
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.

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>

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>
