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.

DeBriefed 15 August 2025: Raging wildfires; Xi’s priorities; Factchecking the Trump climate report
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Blazing heat hits Europe
FANNING THE FLAMES: Wildfires “fanned by a heatwave and strong winds” caused havoc across southern Europe, Reuters reported. It added: “Fire has affected nearly 440,000 hectares (1,700 square miles) in the eurozone so far in 2025, double the average for the same period of the year since 2006.” Extreme heat is “breaking temperature records across Europe”, the Guardian said, with several countries reporting readings of around 40C.
HUMAN TOLL: At least three people have died in the wildfires erupting across Spain, Turkey and Albania, France24 said, adding that the fires have “displaced thousands in Greece and Albania”. Le Monde reported that a child in Italy “died of heatstroke”, while thousands were evacuated from Spain and firefighters “battled three large wildfires” in Portugal.
UK WILDFIRE RISK: The UK saw temperatures as high as 33.4C this week as England “entered its fourth heatwave”, BBC News said. The high heat is causing “nationally significant” water shortfalls, it added, “hitting farms, damaging wildlife and increasing wildfires”. The Daily Mirror noted that these conditions “could last until mid-autumn”. Scientists warn the UK faces possible “firewaves” due to climate change, BBC News also reported.
Around the world
- GRID PRESSURES: Iraq suffered a “near nationwide blackout” as elevated power demand – due to extreme temperatures of around 50C – triggered a transmission line failure, Bloomberg reported.
- ‘DIRE’ DOWN UNDER: The Australian government is keeping a climate risk assessment that contains “dire” implications for the continent “under wraps”, the Australian Financial Review said.
- EXTREME RAINFALL: Mexico City is “seeing one of its heaviest rainy seasons in years”, the Washington Post said. Downpours in the Japanese island of Kyushu “caused flooding and mudslides”, according to Politico. In Kashmir, flash floods killed 56 and left “scores missing”, the Associated Press said.
- SOUTH-SOUTH COOPERATION: China and Brazil agreed to “ensure the success” of COP30 in a recent phone call, Chinese state news agency Xinhua reported.
- PLASTIC ‘DEADLOCK’: Talks on a plastic pollution treaty have failed again at a summit in Geneva, according to the Guardian, with countries “deadlocked” on whether it should include “curbs on production and toxic chemicals”.

Factchecking Trump’s climate report
A report commissioned by the US government to justify rolling back climate regulations contains “at least 100 false or misleading statements”, according to a Carbon Brief factcheck involving dozens of leading climate scientists. The report, compiled in two months by five hand-picked researchers, inaccurately claims that “CO2-induced warming might be less damaging economically than commonly believed” and misleadingly states that “excessively aggressive [emissions] mitigation policies could prove more detrimental than beneficial”80
Spotlight
Does Xi Jinping care about climate change?
This week, Carbon Brief unpacks new research on Chinese president Xi Jinping’s policy priorities.
On this day in 2005, Xi Jinping, a local official in eastern China, made an unplanned speech when touring a small village – a rare occurrence in China’s highly-choreographed political culture.
In it, he observed that “lucid waters and lush mountains are mountains of silver and gold” – that is, the environment cannot be sacrificed for the sake of growth.
(The full text of the speech is not available, although Xi discussed the concept in a brief newspaper column – see below – a few days later.)
In a time where most government officials were laser-focused on delivering economic growth, this message was highly unusual.
Forward-thinking on environment
As a local official in the early 2000s, Xi endorsed the concept of “green GDP”, which integrates the value of natural resources and the environment into GDP calculations.
He also penned a regular newspaper column, 22 of which discussed environmental protection – although “climate change” was never mentioned.
This focus carried over to China’s national agenda when Xi became president.
New research from the Asia Society Policy Institute tracked policies in which Xi is reported by state media to have “personally” taken action.
It found that environmental protection is one of six topics in which he is often said to have directly steered policymaking.
Such policies include guidelines to build a “Beautiful China”, the creation of an environmental protection inspection team and the “three-north shelterbelt” afforestation programme.
“It’s important to know what Xi’s priorities are because the top leader wields outsized influence in the Chinese political system,” Neil Thomas, Asia Society Policy Institute fellow and report co-author, told Carbon Brief.
Local policymakers are “more likely” to invest resources in addressing policies they know have Xi’s attention, to increase their chances for promotion, he added.
What about climate and energy?
However, the research noted, climate and energy policies have not been publicised as bearing Xi’s personal touch.
“I think Xi prioritises environmental protection more than climate change because reducing pollution is an issue of social stability,” Thomas said, noting that “smoggy skies and polluted rivers” were more visible and more likely to trigger civil society pushback than gradual temperature increases.
The paper also said topics might not be linked to Xi personally when they are “too technical” or “politically sensitive”.
For example, Xi’s landmark decision for China to achieve carbon neutrality by 2060 is widely reported as having only been made after climate modelling – facilitated by former climate envoy Xie Zhenhua – showed that this goal was achievable.
Prior to this, Xi had never spoken publicly about carbon neutrality.
Prof Alex Wang, a University of California, Los Angeles professor of law not involved in the research, noted that emphasising Xi’s personal attention may signal “top” political priorities, but not necessarily Xi’s “personal interests”.
By not emphasising climate, he said, Xi may be trying to avoid “pushing the system to overprioritise climate to the exclusion of the other priorities”.
There are other ways to know where climate ranks on the policy agenda, Thomas noted:
“Climate watchers should look at what Xi says, what Xi does and what policies Xi authorises in the name of the ‘central committee’. Is Xi talking more about climate? Is Xi establishing institutions and convening meetings that focus on climate? Is climate becoming a more prominent theme in top-level documents?”

New York Already Denied Permits to These Gas Pipelines. Under Trump, They Could Get Greenlit
The specter of a “gas-for-wind” compromise between the governor and the White House is drawing the ire of residents as a deadline looms.
Hundreds of New Yorkers rallied against new natural gas pipelines in their state as a deadline loomed for the public to comment on a revived proposal to expand the gas pipeline that supplies downstate New York.
New York Already Denied Permits to These Gas Pipelines. Under Trump, They Could Get Greenlit
A “critical assessment” report commissioned by the Trump administration to justify a rollback of US climate regulations contains at least 100 false or misleading statements, according to a Carbon Brief factcheck involving dozens of leading climate scientists.
The report – “A critical review of impacts of greenhouse gas emissions on the US climate” – was published by the US Department of Energy (DoE) on 23 July, just days before the government laid out plans to revoke a scientific finding used as the legal basis for emissions regulation.
The executive summary of the controversial report inaccurately claims that “CO2-induced warming might be less damaging economically than commonly believed”.
It also states misleadingly that “excessively aggressive [emissions] mitigation policies could prove more detrimental than beneficial”.
Compiled in just two months by five “independent” researchers hand-selected by the climate-sceptic US secretary of energy Chris Wright, the document has sparked fierce criticism from climate scientists, who have pointed to factual errors, misrepresentation of research, messy citations and the cherry-picking of data.
Experts have also noted the authors’ track record of promoting views at odds with the mainstream understanding of climate science.
Wright’s department claims the report – which is currently open to public comment as part of a 30-day review – underwent an “internal peer-review period amongst [the] DoE’s scientific research community”.
The report is designed to provide a scientific underpinning to one flank of the Trump administration’s plans to rescind a finding that serves as the legal prerequisite for federal emissions regulation. (The second flank is about legal authority to regulate emissions.)
The “endangerment finding” – enacted by the Obama administration in 2009 – states that six greenhouse gases are contributing to the net-negative impacts of climate change and, thus, put the public in danger.
In a press release on 29 July, the US Environmental Protection Agency said “updated studies and information” set out in the new report would “challenge the assumptions” of the 2009 finding.
Carbon Brief asked a wide range of climate scientists, including those cited in the “critical review” itself, to factcheck the report’s various claims and statements.
