Climate change and biodiversity loss must be tackled together: Report

Dhaka, 21 June, 2021: Asia One has launched Earth One, a new section dedicated to environmental issues — because we love the planet and we believe science. Find articles like thithere.

Biodiversity loss has been eclipsed by climate change on the global agenda but the two issues are closely linked, have similar impacts on human welfare and need to be tackled urgently, together, scientists said on Thursday (June 10).

The destruction of forests and other ecosystems undermines nature’s ability to regulate greenhouse gases in the atmosphere and protect against extreme weather impacts – accelerating climate change and increasing vulnerability to it, a report by the UN agencies on climate change and biodiversity said.

The rapid vanishing of carbon-trapping mangroves and seagrasses, for example, both prevents carbon storage and exposes coastlines to storm surges and erosion.

The report calls for governments to enact policies and nature-based solutions to address both issues.

"For far too long, policymakers tended to see climate change and biodiversity loss as separate issues, so policy responses have been siloed," said report co-author Pamela McElwee, an ecologist at Rutgers University, told a virtual news conference.

"Climate has simply gotten more attention because people are increasingly feeling it in their own lives – whether it's wildfires or hurricane risk. Our report points out that biodiversity loss has that similar effect on human wellbeing."

The report marks the first collaboration of scientists from both the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and the Intergovernmental Panel on Climate Change (IPCC).

Calling on countries to protect entire ecosystems rather than iconic locations or species, the report’s authors hope to influence policy discussions at both the UN conference on biodiversity in October in Kunming, China, and at the UN climate talks being held a month later in Glasgow, Scotland.

"The report will connect the two COPs (summits) in terms of thinking," said Hans Poertner, IPCC co-chair.

Ahead of the Kunming conference, the UN has urged countries to commit to protecting 30 per cent of their land and sea territories by 2030. Experts say at least 30 per cent of the Earth, if not 50 per cent, should be under conservation to maintain habitats under a changing climate.

So far more than 50 countries, including the United States, have made the 30 per cent pledge.

"With this report, the two issues are married now, which is really powerful," said James Hardcastle, a conservationist at the International Union for Conservation of Nature (IUCN). "We can use the momentum to get more commitments from countries on conservation."

Since 2010, countries have collectively managed to add almost 21 million square kilometres – an area the size of Russia – to the global network of protected lands, bringing the current total to nearly 17 per cent of the Earth's landmass, according to a report published last month by the IUCN.

Yet less than eight per cent of these lands are connected – something considered crucial for ecological processes and the safe movement of wildlife. Meanwhile, total marine conservation areas lag at seven per cent, below the 2020 target of 10 per cent.
