Expanding national parks and protected areas will not be enough to halt the destruction of nature, warn leading scientists, who say urgent action on overconsumption, harmful subsidies and the climate crisis is also required to halt biodiversity loss.
Governments are expected to commit to a Paris-style agreement for nature at Cop15 in Kunming, China, later this year, with targets that include protecting at least 30% of the oceans and land by 2030.
An analysis of the draft UN Convention on Biological Diversity (CBD) agreement by more than 50 leading scientists has found that, while expanding protected areas will, if done well, help slow the destruction of the natural world, much more is needed to stop it.Q&A
What is the Kunming biodiversity conference?

Prof Paul Leadley, an ecologist at Paris-Saclay University and co-author of the report, said: “The target of protecting 30% of all land and seas is important and attracting a lot of attention. And expanding protected areas is a good start if done well, but far short of what is needed to halt and reverse biodiversity loss – called ‘bending the curve’ for biodiversity.https://b57053be611a77dfb2ffc6ed091d4d09.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html?n=0
“There is very good evidence that we will fail again to meet ambitious international biodiversity objectives if there’s too much focus on protected areas at the expense of other urgent actions addressing the threats to biodiversity.”
A “massive” reduction in harmful agricultural and fishing subsidies, holding global heating to 1.5C and tackling human overconsumption, including of meat, is necessary, the scientists said, as part of coordinated action across a diverse, interconnected set of “transformative” changes.
The 21 draft targets to be negotiated at Kunming include proposals to eliminate plastic pollution, reduce pesticide use by two-thirds and half the rate of invasive species introduction. The agreement aims to stop what some scientists have called the sixth mass extinction of life on Earth, driven by human behaviour, which threatens ecosystems vital to human civilisation.https://b57053be611a77dfb2ffc6ed091d4d09.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html?n=0
The analysis of the proposed agreement, conducted by the scientific bodies BioDiscovery and the Group on Earth Observations Biodiversity Observation Network (Geo Bon), has been sent to governments, who will give their feedback later this month.
The assessment looked at the impact of three scenarios on halting and reversing biodiversity loss: business as usual, improved quality and quantity of conservation, and transformative change of society. It found that only the last scenario will have the desired effect, assuming global heating is limited to 1.5C.‘We’ll get it done. Come hell, high water or Covid’: Can 2022 be a super year for nature?
“What we’re doing is trying to take the best science and explain why the global biodiversity framework looks like it does. A lot of countries are saying it’s so complicated. We’re trying to explain why you need all the pieces and how each piece fits together,” Leadley said.https://b57053be611a77dfb2ffc6ed091d4d09.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html?n=0
The analysis comes after confusion over the breath and complexity of the draft agreement, which ranges from pollution to the inclusion of indigenous communities.
In March, governments are scheduled to hold in-person negotiations for the first time since February 2020, after several delays to the process. Governments have failed to meet a single target on halting the destruction of nature in the past decade.
María Cecilia Londoño Murcia, a researcher at the Humboldt Institute in Colombia and co-author of the analysis, said: “The sooner we act, the better. Time lags between action and positive outcomes for biodiversity can take decades, so we must act immediately and sustain our efforts if we are to reach the global goals by 2050.”https://b57053be611a77dfb2ffc6ed091d4d09.safeframe.googlesyndication.com/safeframe/1-0-38/html/container.html?n=0

As 2022 begins, there’s a new year resolution we’d like you to consider. We’d like to invite you to join more than 1.5 million people in 180 countries who have taken the step to support us financially – keeping us open to all, and fiercely independent.
In 2021, this support sustained investigative work into offshore wealth, spyware, sexual harassment, labour abuse, environmental plunder, crony coronavirus contracts, and Big Tech. It enabled diligent, fact-checked, authoritative journalism to thrive in an era of falsehood, sensation, hype and breathtaking misinformation and misconception.
In 2022, we’ll be no less active, with a cluster of elections (France, Brazil, the US to say the least), economic pinch points, the next phase of the pandemic, the gathering climate emergency and the first ‘winter World Cup’ to keep us busy.
With no shareholders or billionaire owner, we can set our own agenda and provide trustworthy journalism that’s free from commercial and political influence, offering a counterweight to the spread of misinformation. When it’s never mattered more, we can investigate and challenge without fear or favour.
Unlike many others, Guardian journalism is available for everyone to read, regardless of what they can afford to pay. We do this because we believe in information equality. While others commoditise information, we seek to democratise it. Greater numbers of people can keep track of global events, understand their impact, and become inspired to take meaningful action.
If there were ever a time to join us, it is now. Every contribution, however big or small, powers our journalism and sustains our future. Support the Guardian from as little as $1 – it only takes a minute. If you can, please consider supporting us with a regular amount each month. Thank you.
