NEW YORK (NYTIMES) – The world is failing to address a catastrophic biodiversity collapse that not only threatens to wipe out beloved species and invaluable genetic diversity, but endangers humanity’s food supply, health and security, according to a sweeping United Nations report issued on Tuesday (Sept 15).
When governments act to protect and restore nature, the authors found, it works. But despite commitments made 10 years ago, nations have not come close to meeting the scale of the crisis, which continues to worsen because of unsustainable farming, overfishing, burning of fossil fuels and other activities.
“Humanity stands at a crossroads,” the report said.
It comes as the devastating consequences that can result from an unhealthy relationship with nature are on full display: A pandemic that very likely jumped from bats has upended life worldwide, and wildfires, worsened by climate change and land management policies, are ravaging the American West.
“These things are a sign of what is to come,” said Dr David Cooper, an author of the report and the deputy executive secretary of the United Nations Convention on Biological Diversity, the global treaty underlying the assessment. “These things will only get worse if we don’t change course.”
The report looked at a decade of efforts by national governments. In 2010, after painstaking scientific work and arduous negotiation, almost every country in the world signed on to 20 goals under the convention to staunch the biodiversity hemorrhage.
At the time, the science was already clear: Human activity was decimating animals and plants across the planet, causing a wave of extinctions and throwing ecosystems so out of balance that the domino effects threatened humans themselves. The agreement, with a deadline of 2020 for the new goals, was a hard-won diplomatic triumph.
The report, which assesses progress on the 20 goals, has found that the world is doing far too little.
“Some progress has been made, but it’s not good enough,” said Ms Elizabeth Maruma Mrema, the leader of the UN convention.
As with climate change, scientific alarms on biodiversity loss have gone largely unheeded as the problem intensifies.
Last year, an exhaustive international report concluded that humans had reshaped the natural world so drastically that 1 million species of animals and plants were at risk of extinction.
This year, the World Economic Forum’s annual global risk report identified biodiversity loss, in addition to climate change, as one of the most urgent threats, saying that “human-driven nature and biodiversity loss is threatening life on our planet.”
Last week, a respected index of animal life showed that, on average, the populations of almost 4,400 monitored mammals, birds, reptiles, amphibians and fish had declined by 68 per cent since 1970.
At the global level, only six of the biodiversity convention’s 20 targets were partially achieved and none were fully achieved.
The destruction of habitats such as forests, mangroves and grasslands was not cut in half. Overfishing did not decrease. Governments did not stop subsidising fossil fuels, fertilisers and pesticides that are contributing to the biodiversity crisis.
Indeed, the report estimates that governments around the world spend US$500 billion (S$681 billion) per year on environmentally harmful initiatives, while total public and private financing for biodiversity came to a fraction of that: US$80 billion to US$90 billion.
“Many governments, within their ministry of environment, have a lot of ambition for biodiversity,” said Dr Anne Larigauderie, an ecologist who attended the conference in 2010 that adopted the 20 targets. “But they don’t have enough power compared to the other ministries: agriculture, transportation, energy.”
Despite the overall failure, the report highlights areas of progress around the world, bright spots showing that people have the power to protect and restore nature, not just destroy it.
Conservation efforts have prevented an estimated 11 to 25 bird and mammal extinctions over the last decade; without these actions, researchers calculated, the number most likely would have been two to four times as high.
“If you put in place the policies, they do work,” Dr Cooper said.
To praise and inspire, the report is peppered with success stories big and small. Working with scientists, 20 million Chinese farmers decreased the amount of nitrogen they used on crops like rice and wheat while simultaneously increasing yields.
Indonesia, Liberia and Gambia cracked down on illegal foreign fishing vessels, improving their fish stocks to the benefit of local fisherman. Guatemala rewarded landowners who restored forests with native species.
But such actions must be scaled up significantly. The scale of the crisis and the sheer number of humans living on the planet mean that conservation alone will not be enough.
Instead, the report said, societies will have to transform how they produce and consume food and other goods.
One of the targets addressed this directly: Governments, businesses and stakeholders at all levels were to take steps, at least, to achieve plans for sustainable production and consumption. Three-quarters of the countries reported back on their progress; of those, only one-tenth are on track, the report found.
“Our economic and financing systems are all screwed up,” said Mr Robert Watson, a former chairman of two high-profile panels, one on climate change at the United Nations and the other on biodiversity. “We use gross domestic product as a measure of economic growth. It completely ignores nature. It completely ignores human well-being. And so it’s a very limited concept.”
