KUALA LUMPUR 鈥 The central pledge of a planned new global nature pact 鈥 to protect 30% of the planet鈥檚 land and seas 鈥 is in doubt, with some biodiversity-rich nations refusing to commit because of jitters over funding and implementation, officials have warned.听

A coalition of about 70 countries 鈥 including G7 wealthy governments 鈥 have already promised to conserve at least 30% of their land and oceans by 2030, a pledge known as 30×30, to help curb climate change and the loss of plant and animal species.听

The 30×30 goal is part of a draft global treaty to safeguard plants, animals and ecosystems, due to be finalized next May at the COP15 nature summit in the Chinese city of Kunming, according to the UN Convention on Biological Diversity (CBD).听

鈥淢any countries are supporting it 鈥 but also many countries are not supporting it,鈥 said Elizabeth Maruma Mrema, the CBD鈥檚 executive secretary.听

鈥淚t is still very much for debate,鈥 she told the Thomson Reuters Foundation, adding that effective management of a 30×30 goal would be key.听

Improving protection of natural areas, such as parks, oceans, forests and wildernesses, is seen as vital to maintaining the ecosystems on which humans depend, and to limiting global warming to internationally agreed targets.听

Dozens of nations pledged to do more to conserve nature and make farming greener at the COP26 UN climate talks this month.听

Brian O鈥橠onnell, director of the US-based Campaign for Nature, which is urging leaders to back the 30×30 pledge, said it was 鈥減erhaps the most supported target in the negotiations.鈥澨

There is broad scientific consensus that protecting or conserving at least 30% of land and oceans is the minimum needed to curb biodiversity loss and to reach climate goals, he added.听

But the inclusion of the pledge in the final COP15 accord is far from certain, with improvements needed, said green groups.听

鈥淟ike it or not, 30×30 will be one of the defining issues for COP15,鈥 said Li Shuo, a policy advisor at Greenpeace China.听

鈥淭he Kunming biodiversity summit will not be a success only with this target 鈥 but it will certainly not be seen as a triumph if without [it],鈥 he added.听

WAIT AND SEE听

Southeast Asia covers just 3% of the Earth鈥檚 surface but is home to three of the world鈥檚 17 鈥渕ega-diverse鈥 countries 鈥 Indonesia, Malaysia, and the Philippines.听

It is also the only region where a significant number of countries have yet to back the 30×30 goal, with only Cambodia signing up so far, said Mr. O鈥橠onnell.听

South Africa, meanwhile, has called for a much lower target of 20%, he added, while others like Argentina have questioned the science behind the flagship pledge.听

On a more positive note, India is the latest country to commit to 30×30.听

And at the first part of the COP15 talks, held online last month, host nation China announced a new national parks project that would bring 230,000 square km (88,800 square miles) of land under stronger state protection.听

While China has yet to endorse the 30×30 pledge, the signs are that it may be getting ready to do so at the Kunming summit, said Linda Krueger, director of biodiversity at The Nature Conservancy.听

Opposition to the 30×30 goal is largely linked to the challenges of putting it into practice, such as financing for developing nations, high population density, low levels of biodiversity and lack of domestic laws, environmentalists said.听

But Ms. Krueger said she had only heard Brazil speak out against it clearly. 鈥淢any countries seem to be on the fence, and the support of others is conditioned on adequate financing being made available,鈥 she added.听

Some political leaders have yet to grasp the economic benefits of conservation, with many still relying on exploitation of natural resources to lift people out of poverty, green groups said.听

Others are home to a large proportion of the planet鈥檚 biodiversity and want a protection target higher than 30%.听

Despite these hurdles, there is significant momentum to land the 30×30 goal in the deal, said Susan Lieberman, vice president of international policy at the Wildlife Conservation Society.听

Some countries are still studying how it would play out in their own contexts, she added.听

鈥淢any governments do not realize this is a global target and each country will contribute to achievement of the targets in different ways,鈥 Ms. Lieberman said.听

鈥淕overnments need to look not only at area-based conservation within their own territories, but at what their 鈥榝ootprint鈥 is globally,鈥 she said, pointing to procurement of commodities like timber and fish.听

NO PANACEA听

There are also concerns the 30×30 target will threaten the rights of indigenous and local communities 鈥 and that new protected areas could dispossess those groups, said Guido听Broekhoven, head of policy research and development at WWF International.听

These are the very people who for generations have done the most to sustain, defend and restore biodiversity, he said.听

The 30×30 pledge will be far more effective in halting and reversing biodiversity loss if protected areas are sited in the most important parts of the planet for biodiversity and ecosystem services, he noted.听

That means achieving the target should be 鈥渁 collective, global effort,鈥 he added, calling for more financing.听

Countries with relatively few suitable areas should contribute as far as they can to conservation efforts in other biodiversity-rich nations,听Mr.听Broekhoven听said.听

But 30×30 is not 鈥渁 panacea,鈥澨齢e emphasized, adding that the goal will need to be complemented by reforms to ecologically harmful investment, agriculture and consumption.听

鈥淥n its own, it will be insufficient to reverse the loss of听nature,鈥 he said. 鈥斕Michael Taylor/Thomson Reuters Foundation
