UN report: Humans accelerating extinction of other species

May 7, 2019 — People are putting nature in more trouble now than at any other time in human history, with extinction looming over 1 million species of plants and animals, scientists said Monday.

But it’s not too late to fix the problem, according to the United Nations’ first comprehensive report on biodiversity.

“We have reconfigured dramatically life on the planet,” report co-chairman Eduardo Brondizio of Indiana University said at a press conference.

Species loss is accelerating to a rate tens or hundreds of times faster than in the past, the report said. More than half a million species on land “have insufficient habitat for long-term survival” and are likely to go extinct, many within decades, unless their habitats are restored. The oceans are not any better off.

“Humanity unwittingly is attempting to throttle the living planet and humanity’s own future,” said George Mason University biologist Thomas Lovejoy, who has been called the godfather of biodiversity for his research. He was not part of the report.

“The biological diversity of this planet has been really hammered, and this is really our last chance to address all of that,” Lovejoy said.

Conservation scientists convened in Paris to issue the report, which exceeded 1,000 pages. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) included more than 450 researchers who used 15,000 scientific and government reports. The report’s summary had to be approved by representatives of all 109 nations.

Rising incomes, increased urbanization to underpin seafood consumption growth

May 3, 2019 — The considerable growth in both fisheries and aquaculture production, matched by a rising public awareness of the important role that fish as a food group plays in healthy and diversified diets has driven seafood consumption upwards over the past five decades. Other factors contributing to the steady rise in people eating seafood include reduced wastage, better utilization, improved distribution channels and growing demand.

According to the Food and Agriculture Organization of the United Nations (FAO), in per capita terms, global food fish consumption grew from 9 kg in 1961 to 20.2 kg in 2015, representing an average expansion rate of 1.5 percent per annum. Its preliminary estimates for 2016 and 2017 point to further growth to about 20.3 kg and 20.5 kg respectively. Moreover, since 1961, the average annual increase in global food fish consumption of 3.2 percent has outpaced the population growth (1.6 percent) and exceeded the consumption of meat from all terrestrial animals combined (2.8 percent), and individually (bovine, ovine, pig and other), except poultry (4.9 percent).

In 2015, fish accounted for approximately 17 percent of animal protein, and 7 percent of all proteins, consumed by the global population. As such, it provided about 3.2 billion people with almost 20 percent of their average per capita intake of animal protein.

Of course, consumption varies significantly across and within regions because of the influence of cultural, economic and geographic factors – ranging from less than 1 kg to more than 100 kg. In general terms, though, of the global total of 149 million metric tons (MT) consumed in 2015, Asia accounted for more than two-thirds (106 million MT and 24 kg per capita), while Oceania and Africa consumed the lowest share.

The FAO also highlights that while consumers in many advanced economies have a wide choice of value-added fish products and are not deterred by price increases, their per capita consumption levels have been approaching their “saturation point” in terms of quantity. It notes that the growth of per capita fish consumption in the EU and United States has slowed in the past few years, and also over the past two decades in Japan (albeit from a high level), while the per capita consumption of poultry and pig meat in these markets has increased.

Chinese-led supply constraints to drive global seafood prices up by 25 percent

May 2, 2019 — The rising global demand for seafood and a projected slowdown in the growth of fisheries and aquaculture production, particularly by China – the world’s leading provider of these products – will lead to a decade of higher prices, anticipates the Food and Agriculture Organization of the United Nations (FAO).

In 2016, total fish production reached an all-time high of 171 million metric tons (MT), with wild-capture fisheries and aquaculture providing 53 percent and 47 percent respectively. Of the total, 88 percent or 151 million MT was utilized for direct human consumption. Capture fisheries production accounted for 90.9 million MT, while aquaculture supplied 80 million MT. Although the contribution of farmed species to human consumption is higher than that of wild-caught fish.

Based on the assumption of higher demand and technological improvements, the overall production is expected to continue to expand, reaching 201 million MT by 2030. While this would represent a growth of 18 percent or 30 million MT over 2016, it amounts to an annual growth rate of just 1 percent for the 2016-2030 period, compared with 2.3 percent for 2003-2016.

By 2030, the FAO expects capture fisheries production to reach about 91 million MT, only 1 percent more than in 2016. It foresees that factors influencing this limited growth will include a 17 percent decrease of capture fisheries in China due to the implementation of new policies, which it reckons will be compensated for by increased catches in a number of other regions. In this regard, it believes there will be higher landings from fishing areas where stocks of certain species are recovering due to improved management, as well as increased catches in waters of the few countries where there are underfished resources, as well as where new fishing opportunities exist or where fisheries management measures are less restrictive.

In addition, the FAO believes there’ll be enhanced use of fisheries production, including reduced onboard discards, waste, and losses as driven by legislation or higher market fish prices. But it also acknowledges that in some years, the El Niño phenomenon can be expected to reduce catches in South America, especially for anchoveta, resulting in an overall decrease of world capture fisheries production of about 2 percent in those years.

Will plant-based fish food make aquaculture more sustainable?

April 12, 2019 — Replacing fish food with plants may not be as planet-friendly as it seems, according to a new study on the ecological impact of feeding soy and other land-grown crops to farmed seafood. These plant-based feeds are an alternative to, well, other sea creatures, which is what many species like shrimp and salmon eat in the wild. Published in the science journal Sustainability, the new study—which involved which involved an international and multidisciplinary team of experts—quantifies the effects that plant-based feeds have on land, water, and fertilizer use. The numbers that emerge challenge the prevailing notion that simply swapping fish-based fish food for plant-based fare can minimize the environmental footprint of aquaculture.

The interlocking limitations of fish-based feed, also known as fishmeal, have long confounded the aquaculture industry. For one, its ingredients—small, wild fish lower in the food chain, known as forage fish—are a finite resource. And as the global appetite for seafood continues to rise, so does the pressure to catch more. That means that fishmeal is becoming more costly and harder to source. As a result, producers have been trying to reduce their reliance in recent years.

“When shrimp farming became very popular 30 to 35 years ago, there was kind of a preference to grow as many shrimp as you can, as fast as you can, and get them out on the market,” says Cheryl Shew, a representative of specialty feed manufacturer Ziegler Bros. Inc. But like much of the industry, Ziegler began to experiment with soy as a partial substitute fishmeal in its feed products beginning in the early aughts, Shew tells me.

So why not just completely replace fishmeal with plants? It’s not as easy as it sounds—or as environmentally-sound, as it turns out.

China faces big decision on WTO reform deal

March 28, 2019 — The pressure is on this month as negotiators seek to find common ground and to advance the cause of a World Trade Organization agreement on fishery subsidies by the end of the year.

The WTO Director-General Roberto Azevêdo has said subsidies by member states for fuel have contributed to overfishing, and illegal and unregulated fishing. He called it “one of the important issues of our time.”

An estimated USD 20 billion (EUR 17.8 billion) is paid out annually to subsidize the cost of fuel that allows vessels to operate thousands of miles from home. The bulk of the subsidies are paid out by a handful of nations, and around 85 percent of the figure goes to large-scale industrial fleets, rather than smaller near-shore artisanal fisheries.

The pressure was ramped up in 2015 when all United Nations member states agreed Sustainable Development Goal 14.6 to eliminate or prohibit harmful fishery subsidies by 2020. The goal was a priority for developing countries depending on the sea for protein.

There are some reasons for optimism – the WTO director general told a WTO plenary in February that progress had been made in the negotiations among the technocrats. But he said now is time for high-level political commitment to get the deal done.

Will Large Protected Areas Save the Oceans or Politicize Them?

March 25, 2019 — How can we save the oceans? They cover two-thirds of the planet, but none are safe from fishing fleets, minerals prospectors, or the insidious influences of global warming and ocean acidification.

In the past decade, there has been a push to create giant new Marine Protected Areas (MPAs). They now cover nearly 9.7 million square miles, equivalent to more than the land area of North America. Cristiana Pașca Palmer, executive secretary of the UN Convention on Biological Diversity, says the world is on course reach the convention’s target of having a tenth of the oceans protected by next year.

But questions are being raised. The growth has been driven by the formation of giant MPAs bigger than many countries, often in remote regions where the threat to biodiversity is lower. So, critics are asking, are countries creating big distant MPAs to distract attention from the harder task of protecting trashed coastal ecosystems closer to home? And is there a geopolitical game afoot, a stealth rush to control the oceans for political ends? And does that explain why half of the ocean waters covered by MPAs are in the hands of the United States and two former European colonial powers, Britain and France?

Most ocean scientists see the rush to create vast MPAs as a boon to marine conservation. They are cost-effective, connect different marine ecosystems, and encompass larger parts of the ranges of migrating species such as whales and tuna, protecting “corridors of connectivity among habitats in ways not afforded by smaller MPAs,” says Bethan O’Leary, a marine scientist at the University of York in England.

UN, Oceana, insurer issue guidelines to stop IUU fishing

February 28, 2019 — Several environmental advocacy groups including UN Environment and Oceana have partnered with major insurer Allianz to write guidelines that could help the marine insurance industry better detect and prevent instances of illegal, unreported and unregulated (IUU) fishing.

The newly issued risk assessment guidelines to marine insurers include a checklist of 18 warning signs to detect higher risk vessels and contracts, Oceana said in a press release.

In 2017, the UN Environment’s Principles for Sustainable Insurance initiative recruited several major insurers including Allianz, AXA, Generali, Hanseatic Underwriters and The Shipowners’ Club to join a statement to combat IUU.

Aquaculture does little to conserve wild fisheries, according to study

February 11, 2019 — New research finds that aquaculture, or fish farming, does not help conserve wild fisheries.

“Our fundamental question with this study was: does  conserve wild fish?” says Stefano Longo, an associate professor of sociology at North Carolina State University and first author of a paper on the work. “The answer is: not really.”

To determine the impact of  efforts on traditional, or “capture” fisheries, Longo and his collaborators looked at data from the World Bank and the Food and Agriculture Organization of the United Nations, from 1970 to 2014. Specifically, the researchers evaluated data that shed light on changes in aquaculture and traditional fisheries, such as aquaculture production numbers and the number of fish harvested by wild fisheries.

“We found that aquaculture has expanded production, but does not appear to be advancing fishery conservation,” Longo says. “In fact, aquaculture may contribute to greater demand for seafood as a result of the social processes that shape production and consumption.

“In other words, aquaculture is not taking the place of traditional fishing efforts, or even necessarily reducing them,” Longo says.

Ocean Warming Is Accelerating Faster Than Thought, New Research Finds

January 14, 2019 — Scientists say the world’s oceans are warming far more quickly than previously thought, a finding with dire implications for climate change because almost all the excess heat absorbed by the planet ends up stored in their waters.

A new analysis, published Thursday in the journal Science, found that the oceans are heating up 40 percent faster on average than a United Nations panel estimated five years ago. The researchers also concluded that ocean temperatures have broken records for several straight years.

“2018 is going to be the warmest year on record for the Earth’s oceans,” said Zeke Hausfather, an energy systems analyst at the independent climate research group Berkeley Earth and an author of the study. “As 2017 was the warmest year, and 2016 was the warmest year.”

As the planet has warmed, the oceans have provided a critical buffer. They have slowed the effects of climate change by absorbing 93 percent of the heat trapped by the greenhouse gases humans pump into the atmosphere.

“If the ocean wasn’t absorbing as much heat, the surface of the land would heat up much faster than it is right now,” said Malin L. Pinsky, an associate professor in the department of ecology, evolution and natural resources at Rutgers University. “In fact, the ocean is saving us from massive warming right now.”
