Only 10 Vaquita Porpoises Remain in the World, Scientists Announce
Scientists announced Thursday that only 10 vaquita porpoises likely remain in the world and that the animal's extinction is virtually assured without bold and immediate action.
The vaquita, the world's smallest and most endangered cetacean, is found only in Mexico's northern Gulf of California. The release of the new vaquita estimate comes just two days after reports of the possible first vaquita mortality of 2019. More details are expected in the coming days.
Thursday's announcement from the International Committee for the Recovery of the Vaquita also calls on Mexico President Andres Manuel Lopez Obrador to end all gillnet fishing and adopt a "zero tolerance" policy of enforcement in the vaquita's small remaining habitat. The committee is an international team of scientific experts assembled in 1996 to assist in vaquita recovery efforts.
"One of Earth's most incredible creatures is about to be wiped off the planet forever," said Sarah Uhlemann, international program director at the Center for Biological Diversity. "Yet Mexico has only made paper promises to protect these porpoises from deadly nets, without enforcement on the water. Time is running out for President Lopez Obrador to stop all gillnet fishing and save the vaquita."
The vaquita faces a single threat: entanglement in illegal gillnets set for shrimp and various fish species, including endangered totoaba. Totoaba swim bladders are illegally exported by organized criminal syndicates from Mexico to China, where they are highly valued for their perceived medicinal properties.
Despite efforts in Mexico to curb gillnet fishing of shrimp and other fish and efforts in China to reduce demand for totoaba, the vaquita's population dropped 50 percent in 2018, leaving an estimate of around 10 remaining vaquita, with no more than 22 and perhaps as few as six.
"There is only the tiniest sliver of hope remaining for the vaquita," said Kate O'Connell, a marine wildlife consultant with the Animal Welfare Institute. "Mexico must act decisively to ensure that all gillnet fishing is brought to an end throughout the Upper Gulf. If the vaquita is not immediately protected from this deadly fishing gear, it will go extinct on President Lopez Obrador's watch."
In 2017, in the face of international pressure, Mexico banned the use of most gillnets within the vaquita's range, but enforcement has been lacking. For example, during the 2018 illegal totoaba fishing season, nearly 400 active totoaba gillnets were documented in a small portion of the vaquita's range, and gillnets continue to be found within the vaquita refuge. Recent violence against conservationists in the region has limited critically important net removal efforts.
"If Mexico doesn't want to be guilty of wiping out a species, it needs to secure 100 percent gillnet-free habitat now," said Zak Smith, a senior attorney with the Natural Resources Defense Council's Marine Mammal Protection Project. "What's happening to the vaquita is a disgrace and entirely preventable, yet the Obrador administration has not committed to a robust vaquita recovery plan and has already missed deadlines on vaquita conservation commitments."
"The organized criminal networks trafficking totoaba swim bladders from Mexico to China are responsible for the illegal fishing nets driving the vaquita to extinction," said Clare Perry, ocean campaign leader for the Environmental Investigation Agency. "Unless Mexico gets serious about enforcement and works with China and key transit countries to dismantle those networks, there is no hope for the remaining vaquita."
Despite the marine mammal's alarming decline, the international committee emphasized that the vaquita is not extinct and that recovery remains possible. They are still producing offspring, and the remaining animals are healthy, showing no signs of disease or malnutrition. The international community plays a critical role in vaquita conservation.
In 2018 a U.S. court temporarily banned the import of seafood caught with dangerous gillnets in vaquita habitat. This year parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the World Heritage Convention are considering additional conservation measures for the vaquita and totoaba.

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. 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>
