China’s effort to build large solar power “bases” in and around the desert is a major part of its current renewable plan.
What is less known is that the initiative – which has expanded rapidly in the country’s arid north and northwest – is also a part of China’s campaign to combat desertification, an issue increasingly exacerbated by climate change.
For more than four decades, Beijing has been trying to prevent sand from degrading its land and forming dust storms with an afforestation programme called the “Three-North Shelterbelt” (三北防护林).
Over the past two years, the programme – described as China’s “war on sand” by the media – has been boosted by the development of large-scale solar bases in far-flung regions, such as Xinjiang and Inner Mongolia.
Installing solar panels in the desert can not only generate power, but also help prevent sand dunes from moving, according to Dr He Jijiang, executive deputy director of the Research Center for Energy Transition and Social Development at Tsinghua University, Beijing.
Energy companies’ investments also provide financial support to many regions’ sand-control campaigns – an apparent obstacle in the past – Dr He tells Carbon Brief at a side event in the China pavilion at the ongoing 16th session of the conference of parties (COP16) of the United Nations Convention to Combat Desertification (UNCCD) in Riyadh, Saudi Arabia.
Taming of the sand
China is one of the worst-hit countries by desertification, which essentially means land degradation in dry lands. When land degrades, it becomes less healthy and productive.
Nearly 18% of China’s landmass – roughly seven times the size of the UK – is affected by the issue, according to statistics reported by Guan Zhi’ou, director of China’s National Forestry and Grassland Administration and the head of the Chinese delegation to COP16, in November.
China’s effort to combat desertification has a strong link with its – and the world’s – climate actions.
Soil is the second largest natural carbon sink on Earth after oceans and stores a large amount of carbon. When land degrades, not only does it lose the ability to store as much carbon, it can also release carbon into the atmosphere, driving further climate change.
On the other hand, climate change accelerates land degradation and China is on the front line. The country has seen the largest total area shift from non-dryland into drylands over the past three decades, according to a major scientific report published by the UNCCD at COP16. This means more parts of China are now prone to land degradation.
Since the introduction of the Three-North Shelterbelt programme in 1978, China has adopted a series of measures to fight desertification, from planting sand-blocking vegetation to laying straw on the ground in the shape of checkerboards to prevent its vast deserts from expanding. These solutions have enabled the country to protect about 360,000km2 of desertified land and to rehabilitate 79,000km2 of it, Guan said.
The ancient Chinese people built the Great Wall and Beijing now intends to build a “Green Great Wall”. According to the plan, the Three-North programme will see a total of 350,000km2 of trees planted in northern regions over the space of 73 years – until 2050 – to block out dust storms, stabilise the soil and improve land fertility.
Research by the Chinese Academy of Sciences showed that emissions averaging 213m tonnes of carbon dioxide equivalent were absorbed by forest, land and the environment every year between 1980 and 2015, due to the Three-North Shelterbelt programme, according to a release published by the National Forestry and Grassland Administration.
Solar solution
China’s plan for renewable energy from 2021 to 2025 calls for the “large-scale development” of its sand-plus-solar anti-desertification method, a concept Beijing started promoting around two years ago.
The concept centres around managing arid areas via building and maintaining solar farms. It stems from years of experience accumulated by Chinese solar developers, which have built solar farms in the desert for more than a decade – with varying degrees of success.
“Building solar farms needs a lot of space. China has vast deserts, so [companies] wanted to take advantage of it,” Dr He explains.
But to operate solar farms in such harsh conditions, these companies must first take various protective measures – and these measures helped combat desertification, too.
For example, companies need to put up fences around their solar farms to stop animals from entering, install anti-dust nets to prevent sand from gathering on equipment and make straw checkerboards around their bases to prevent nearby sand dunes from shifting, Dr He says.
Solar panels also bring benefits to the ground underneath. For example, they can reduce water evaporation by blocking out direct sunshine, according to Dr Chen Siyu, a professor at the college of atmospheric sciences at Lanzhou University in Lanzhou, a city situated on the edge of the Gobi desert in China.
Solar panels can “significantly increase” the soil moisture of dry regions and, therefore, help plants to grow, Dr Chen tells Carbon Brief. A 2021 study conducted in northwest China projected that the soil moisture would increase by up to 113.6% when it is sheltered.
“Solar panels can also form a natural barrier, helping to shed wind speed and prevent dust storms from occurring and spreading,” she says.
Ramping up transition
The construction of solar farms also injects financial support to many regions’ sand-control campaigns, providing incentives for them to carry on, Dr He notes.
“In the past, planting trees only brought ecological benefits, not economic returns,” he says. “Now, if a company wants to build a solar power station, it needs to cover all related costs, from hiring equipment to growing plants.”
Ramping up the solar-plus-sand method can scale up China’s renewable deployment, as well as improving soil conditions by bringing greenery, vegetable plots and livestock to the desert and barren land. Because of this, dryland has become “a type of resource”, Dr He says.
The Chinese government has been pushing the concept as a way to upscale the development of desert-based solar.
But there are concerns over whether the country’s grid is ready to transport such a large amount of solar power from remote areas to big cities on the eastern coast thousands of kilometres away.
Dr He recognises the challenge. “We don’t have enough long-distance transmission lines, but we are building many,” he says.

Explainer: How China’s renewables rollout boosts its ‘war on sand’
After witnessing the effects of sea-level rise in the low-lying island nation of Tuvalu, Pacific leaders on Tuesday used the pre-COP31 summit in Fiji to voice their frustration at the difficulties they have experienced in tapping the global climate finance system.
A small group of government leaders, climate negotiators and heads of development banks and climate funds took a trip to Tuvalu’s Funafuti atoll on Tuesday morning, travelling by road over land just 10-20 metres wide to visit a project that is building barriers to keep the sea from the land.
They then flew to Fiji for the pre-COP summit, where several Pacific leaders said they had been let down by the insufficient quantity, bad terms and slow speed of international finance to help them adapt to a warming climate that is bringing higher oceans, drought and more powerful storms to their shores.
“Right now, our islands are like a canoe that has been rammed by a massive foreign ship. Our canoe is taking on water, we are sinking, and what is the world’s response?” asked Palau’s President Surangel Whipps Jr.
“They hand us a tiny patch to cover a gaping hole,” he continued, “but the bureaucratic process just to receive that patch is so slow that the water fills the hole while we wait. Then to rebuild the vessel so that we can survive the next storm, we are offered loans, debt that adds weight to a sinking boat packaged in red tape so thick we can barely access it. And while we wait, the water continues to fill.”
Pacific leaders and Australia called again on governments to invest in the new Pacific Resilience Facility (PRF), which has been designed by the Pacific Islands Forum and is seeking $500 million in investments by COP31 in November.
It has around $180 million so far, but did not receive additional pledges during the UN General Assembly in New York. The PRF aims to invest to generate annual returns which it can give to projects like water tanks for drought-hit communities.
Witnessing sea level rise
The annual pre-COP gathering is usually a low-profile technical meeting of climate negotiators. But this year, Australia – which is the president of negotiations at COP31 – partnered with the Pacific to introduce a “leaders segment” in an attempt to shine a spotlight on climate issues affecting the region.
Fourteen government leaders – from Australia, Timor-Leste, Mauritius and the Pacific – made the trip. They were joined by the European Union’s climate commissioner Wopke Hoekstra, the heads of the Green Climate Fund and the Asian Development Bank and former Australian prime minister Julia Gillard.
On their return to Fiji, Solomon Islands Prime Minister Matthew Wale told the pre-COP leaders roundtable that the sea level rise they had witnessed was personal for him.
“Tuvalu was not just a site visit for me. I saw the story of my own saltwater people,” he said, adding that he, his daughter and his grandfather had lost their houses to sea level rise and that three-quarters of his electorate live on land that will be underwater in the next 30 years.
From the other side of the world, Antigua and Barbuda’s environment minister Michael Joseph said Tuvalu’s problems felt similar to those of his own Caribbean islands. “I saw vulnerable communities… just metres from the sea and people determined to remain on their land, preserve their culture and way of life,” he said.
A group of Fijian schoolchildren told the leaders it was not just sea level rise the Pacific struggles with but also heatwaves, droughts and storms, which worry their families and prevent them from learning.
Climate finance red-tape
Several Pacific leaders criticised the world’s leaders for not doing enough to combat climate change. Cook Islands Prime Minister Mark Brown expressed disappointment that only two non-Pacific leaders had come to the pre-COP, a fact Australian media widely picked up on to label the event a flop and question its A$20 million (US$14m) price tag.
“We’ve heard a lot of numbers these last two days,” Brown said. “Let me share one of my own. More than 50 invitations extended to world leaders… to see for themselves what high emissions are doing to our nations and our ocean – an ocean that covers nearly one-third of the Earth’s surface.”

He called for more climate finance for the Pacific, asking “if the world is prepared to assess our suitability for climate finance, why is it not equally prepared to scrutinise whether those responsible for delivering it are meeting their obligations?”
Like Palau’s president Whipps, Naoero’s President David Adeang criticised the red tape that is hindering access to climate finance as well as a lack of money, complaining especially about “complicated procedures, heavy reporting, delays in approval and disbursement”.
Adeang added that “the way we assess vulnerability matters”, adding that it should be measured by more than income. Naoero, for example, is classified by the World Bank as high-income, restricting which climate finance it is eligible for.
Action plan to improve access
On Thursday, the Australian government will present a statement and action plan on improving access to climate finance for small island developing states and least developed countries, which it is asking other countries and organisations to endorse.
The statement addresses some of these Pacific complaints as well as acknowledging that progress has already been made on simplifying access by multilateral development banks and climate funds.
In Fiji, Asian Development Bank head Masato Kanda said his institution is “tailoring our finance and operations to island realities” because “your children and their children should be able to grow old in the countries their ancestors have called home for millennia”.
The executive director of the Green Climate Fund (GCF), Mafalda Duarte, said that the GCF-backed coastal adaptation project leaders visited in Tuvalu shows that “climate finance works” although – as the project took eight years to implement – “it takes time, and therefore we have no time to waste”.
Australia calls for optimism
While Pacific leaders expressed concern that the world is set to blast past its agreed 1.5C warming limit, endangering their nations, Australia’s Prime Minister Anthony Albanese called for “optimism”. “If people think there is no hope, then they will not strive to get the change that we need,” he said.
He said that when he attended his first COP in 2005, Australia’s renewable energy target was 2%. Its target is now 82% renewable electricity by 2030.
While Albanese promoted Australia’s success at electrifying homes and businesses and rolling out renewables, he has been criticised by climate campaigners for extending the production of fossil fuels, including coal – largely for export.
France’s Minister for Ecological Transition Monique Barbut defended the European Union’s climate action at the pre-COP meeting. She said the continent was heating up and reducing emissions faster and providing more climate finance than anywhere else in the world.
“It is time for all major emitters to step up and do their fair share” on climate finance, she said. Most developing countries with large emissions have fiercely resisted joining the club of climate finance donors, arguing they have played a disproportionately small historic role in causing climate change.
Barbut, as well as Palau’s president Whipps, called for the next flagship scientific assessment report of the Intergovernmental Panel on Climate Change (IPCC) to be finished by COP33 in 2028, in time to inform the next global stocktake of national climate action.
This timeline has been opposed by countries like India, Saudi Arabia and China, who argue it would put an unfair burden on developing countries. Barbut said countries should “support the work of the IPCC rather than sabotage its calendar”.
Barbut said that governments should agree at COP31 to aim to raise the share of “clean electricity” in final energy consumption to 35% by 2035. The Turkish and Australian governments have pushed for this goal although without specifying that the electricity should be “clean”. Barbut added that COP31 should also agree to cut emissions of methane, a particularly potent greenhouse gas.

Pacific leaders rail at climate finance failures after pre-COP trip to Tuvalu
Jacynta Fa’amau is a Pacific campaigner at global grassroots climate movement 350.org and a secretariat member of Pacific Climate Warriors.
The first thing that struck me was the sheer size of Queensland’s Saraji coal mine. Standing at the edge of the enormous pit, my brain scrambled for words as I scanned the earth’s open wound – a whole island could probably fit inside it.
Looking down, I noticed footprints of an emu and a koala, pressed and dried in what was once a puddle – signs of how drought had driven animals in desperate search of water, so dangerously close to the coal trucks and heavy machinery ahead.
Earlier this year, I joined a small group of Pacific Islanders on a journey through the Bowen Basin to learn from First Nations communities battling Australia’s mammoth coal industry. Of the more than 40 coal mines operating in the area, BHP & Mitsubishi Alliance’s Saraji mine is one of the largest. So it came as a painful shock to us when in August, the Australian government approved the mine’s extension just months after our visit.
