China waste management

In China, a significant shift has occurred in waste management, moving from a critical “garbage siege” to an unexpected “garbage shortage.”

In 2011, the documentary “Beijing Besieged by Waste” by filmmaker Wang Jiuliang highlighted the severe waste problem in and around Chinese cities, where landfills were overwhelmed. However, in just over a decade, China’s waste treatment capabilities have expanded dramatically. The number of waste incineration plants surged from 130 in 2011 to 927 in 2023, now accounting for nearly half of the global total. This rapid expansion has resulted in many incineration plants operating below their capacity due to an insufficient supply of waste.

To address this “garbage shortage,” China has implemented innovative solutions:

Excavating Old Landfills: Some cities are digging up older landfills to retrieve buried waste for incineration, though this practice carries potential pollution risks.

Exporting Waste Treatment Technology: Having banned solid waste imports by January 1, 2021, China is now exporting its advanced waste treatment technologies and solutions, particularly to Southeast Asian countries facing similar waste management issues.

Several key factors have driven this transformation:

– Technological Breakthroughs: China has developed advanced domestic waste incineration technologies, such as the grate furnace and reverse push grate, which are efficient in treating waste with high moisture content and low calorific value, common in China. These technologies ensure thorough combustion, effective pollutant removal, and efficient energy recovery, proving more cost-effective than imported alternatives.

– Policy Guidance and Economic Incentives: Government policies, like the “13th Five-Year Plan” for urban domestic waste harmless treatment facilities, have set clear targets for incineration capacity. Financial incentives, including construction subsidies, waste treatment fees (around 130 yuan per ton), long-term operating rights (up to 30 years), and subsidized electricity prices for waste-to-energy projects, have made these ventures highly profitable.

– Waste Classification System: The mandatory waste classification policies implemented in 2019 have significantly improved resource recovery, reduced the load on incineration plants, and increased the overall efficiency of waste treatment and resource utilization.

China’s success in waste management exemplifies a broader trend where environmental challenges are converted into industrial opportunities through practical actions and technological innovation, moving beyond mere theoretical discussions.

Grey larva of the Yangtze sturgeon hatched

The first tiny, no bigger than a grain of rice, half-translucent grey larva of the Yangtze sturgeon hatched on April 16, 2025, in the shallow waters of the Chishui River in SW China’s Guizhou. The adult sturgeons were released into the modified habitat on April 3, 2025, and fertilized eggs were observed on April 12, 2025. It is the first successful natural reproduction of the critically endangered Yangtze sturgeon in the wild in over two decades.

This breakthrough was the culmination of years of painstaking efforts by researchers from the Institute of Hydrobiology of the Chinese Academy of Sciences, the Chinese Sturgeon Research Institute under the China Three Gorges Corporation, and other institutions, organized by the Ministry of Agriculture and Rural Affairs. https://www.facebook.com/jeff.mah.5/videos/696948593203867/?__cft__[0]=AZWbE99JbBmmdIpgvVhCCL0cVgglCWlYKTYJ7WKRZZ8XzL7d2v1znxzmcLrXmOuM5QyF-UReevFtGoVW_e3yHQLAjs-3UAtia2mMw_VuGlJPl7umkfor4cmvjckQVNH3nCxzIQgM-9sJ98IHPbx6n11FVFhQ6c-5jgpr2GJuWjOJNQ&__tn__=%2CO%2CP-R

China’s ambitious water diversion and Yellow River management

China’s ambitious water diversion and Yellow River management projects represent a bold vision to address water scarcity, ecological degradation, and food security challenges.

1. Land Use Challenges & Historical Context

Limited Arable Land: Despite China’s vast territory, only ~12% is arable due to deserts (e.g., Taklamakan, Gobi), mountains, and the Qinghai-Tibet Plateau.

Historical Desertification: Post-ice age humidity in the Northwest declined due to natural climate shifts and human activities (overgrazing, agriculture). Restoring this region requires addressing both water supply and ecological balance.

2. Water Diversion Projects: Key Components

A. Tibetan Plateau Water Utilization

Dam Construction: Mega-dams on the Yarlung Tsangpo (Brahmaputra), Lancang (Mekong), and Jinsha (Yangtze tributary) could harness hydropower and regulate water flow.

Challenge: Geopolitical tensions (India, Bangladesh, Southeast Asia) and ecological risks (sediment blockage, biodiversity loss).

Pipeline Networks: Underground/surface pipelines could minimize evaporation and terrain obstacles.

Innovation Needed: Cost-effective, earthquake-resistant infrastructure for the plateau’s harsh conditions.

B. Qaidam Basin as a Hydrological Hub

Lake Restoration: Diverting Yarlung Tsangpo water to the Qaidam Basin could create a giant inland lake, improving regional climate and serving as a distribution node.

Potential Impact: Increased rainfall in surrounding deserts (e.g., Taklamakan) via enhanced evaporation cycles.

C. Yellow River Augmentation

Interbasin Transfers: Supplementing the Yellow River with Tibetan waters could alleviate shortages in North China.

Ordos Plateau Reservoir: A mega-reservoir here could stabilize water supply for agriculture (e.g., Fen River Valley) and industry.

Downstream Management: Dredging sediment and linking to the Zhang River would improve navigation and flood control.

3. Ecological & Agricultural Transformation

Desert Reclamation: Controlled irrigation (e.g., drip systems) could convert arid lands into productive oases, but soil salinity must be managed.

Loess Plateau Afforestation: Increased water supply could support reforestation, reducing erosion and Yellow River siltation.

4. Challenges & Risks

Environmental Costs: Altering river flows may disrupt ecosystems (e.g., fish migration, wetland loss).

Geopolitical Tensions: Downstream countries (India, Vietnam, etc.) may oppose diversion of transboundary rivers.

Economic Feasibility: Estimated costs could exceed $100 billion; long-term maintenance is critical.

5. Global Precedents & Lessons

Successes: Israel’s drip irrigation, U.S. Hoover Dam, and China’s South-North Water Transfer Project offer insights.

Failures: The Aral Sea disaster underscores the risks of over-diversion.

Conclusion

China’s plan is a monumental effort to reshape its hydrology and ecology. If executed sustainably, it could:

Add millions of hectares of arable land.

Mitigate northern water shortages.

Boost renewable energy via hydropower.

However, it requires:

International cooperation on transboundary rivers.

Robust environmental safeguards.

Adaptive management to balance human and ecological needs.

This project could redefine China’s landscape, but its success hinges on balancing ambition with prudence. https://www.facebook.com/jeff.mah.5/videos/1925702144640987/?__cft__[0]=AZVsnatRAl90m-KwQ3sr1p4aI0tCdrdKIj0Xg5PsNR60ShtUxXkMnMXnAAUOEmZTwbkpQuIUaqPhUBnhZarXObmq0qXlsav6rcSMyxVtP8lkkowsCI_ruPoG6gkPwTSkaj6dPHB3t4XoQdJXnB_ziXPhrz5D-AA0ni5RmqtrXETJww&__tn__=%2CO%2CP-R

The Taklamakan Desert ecological transformation

The Taklamakan Desert, China’s largest desert, is undergoing a significant ecological transformation through a multi-pronged approach. These efforts are focused on creating a sustainable environment, combating desertification, and fostering economic development in the region.

A cornerstone of this transformation is the establishment of a 2,761-kilometer green protective belt encircling the desert. With only 130 kilometers remaining to be completed this year, this vast green barrier is crucial in preventing sand encroachment and expanding the vegetated areas.

To support these large-scale greening initiatives, a dedicated botanical garden exceeding 300 acres in Xinjiang’s Bayingol Prefecture is engaged in vital research and cultivation. This facility focuses on identifying and growing plants specifically adapted to harsh desert conditions, which are then transplanted to stabilize the desert’s edges.

Sustainable desert management practices are also being implemented, integrating ecological preservation with economic benefits:

Economic Crops: The successful cultivation of drought-resistant economic crops, such as corn and rice, serves a dual purpose. These crops act as a natural barrier against shifting sands while providing significant economic returns for local farmers. A notable example is the 62,000 mu of rice cultivated within the desert, which has yielded a bountiful harvest.

Water Management: Advanced irrigation systems, including spray and drip irrigation, are being employed to efficiently utilize water resources from the Tianshan Mountains, sustaining both native plants and agricultural crops. Furthermore, the desert possesses a unique underground reservoir of brackish water, which is being leveraged to support the growth of salt-tolerant plant species.

Photovoltaic Desert Control: Innovative use of solar panels extends beyond clean energy generation. These installations are strategically placed to slow down sand movement, demonstrating a synergistic approach to environmental control and renewable energy. https://www.facebook.com/jeff.mah.5/posts/pfbid02rBGrCFMH9KRrQB6e71JDd6QsvHErzkcG4YS2MXQnuqURNzR8vgVkPj8WSss3uxC4l?__cft__[0]=AZVUl1ZYR-5Yy0IGtgFRIzAlROv-vdvu6mplwlGtnNALKMqa08ZJrJIUQGpUQRyXsABMNjeHZL0WjRysmOW2ByTyQmO7kStibHiMUazTRzzQwly_fo6z40T1PeNDWAM4U2c_qv41ziBFUKs_4cIhsvqziJVJx3XiYxYmkp6u7N_TFQ&__tn__=%2CO%2CP-R

Water diversion projects from Tibet to Xinjiang

Water diversion projects from Tibet to Xinjiang.

“Is there a water diversion project from Tibet to Xinjiang?”

“What is the feasibility of diverting water from Tibet to Xinjiang?”

“Environmental impact of water diversion from Tibet to Xinjiang”

“Technical challenges of Tibet to Xinjiang water diversion”

“Hongqi River Project”

“China’s water diversion plans western region”

“Water scarcity Xinjiang”

“Tibetan plateau water resources”

This will allow me to gather more specific details on the existence, feasibility, and impact of such a project.

There have been proposals and discussions in China about large-scale water diversion projects from the Tibetan Plateau to Xinjiang and other arid parts of Northwest China, with the “Hongqi River Project” (Red Flag River Project) being a prominent conceptual plan. However, it’s crucial to understand the current status and complexities surrounding such an undertaking.

The Concept of Water Diversion from Tibet to Xinjiang:

Motivation: The primary motivation behind these proposals is to address severe water scarcity in Xinjiang and other arid regions of Northwest China, which are crucial for agriculture, industry, and population growth. The idea is to tap into the abundant water resources of the Qinghai-Tibet Plateau, often referred to as Asia’s “water tower.”

Hongqi River Project: This is a conceptual proposal that has gained attention, aiming to annually divert massive amounts of water (up to 60 billion cubic meters) from major rivers on the Qinghai-Tibet Plateau, including transnational rivers like the Yarlung Tsangpo (Brahmaputra), Nu River (Salween), and Lancang River (Mekong), to Xinjiang and other northwestern provinces like Gansu and Ningxia. Proponents envision it creating vast arable land and oases.

Historical Ideas: The idea of diverting Tibetan water to Xinjiang dates back to the late 1950s, with prominent figures like meteorologist Zhu Kezhen advocating for it.

Challenges and Realities:

Feasibility and Cost: Experts and even some Chinese scientists have expressed significant skepticism about the feasibility and enormous cost of such projects. The “Hongqi River Project” alone is estimated to cost trillions of yuan (hundreds of billions of USD).

Engineering Challenges: The Tibetan Plateau’s high altitude, complex terrain, harsh frozen conditions, and seismic activity pose immense engineering hurdles. Proposed schemes involve building extremely high dams and tunneling through extensive mountain ranges, with some tunnels potentially stretching over 1,000 kilometers. The technological solutions for such large-scale and complex undertakings at high altitudes are largely untested.

Environmental Impact: There are significant concerns about the potential environmental consequences, both within China and for downstream countries that rely on these international rivers. The proposed diversion of large quantities of water could drastically alter ecosystems, impact biodiversity, and affect water security for millions of people in neighboring nations (e.g., India and Bangladesh for the Brahmaputra).

Socioeconomic Factors: The projects would necessitate massive resettlement of populations and involve complex social and economic considerations. The high cost of diverted water would also be a significant factor.

Official Denials: While proposals circulate, Chinese officials have, at times, denied the existence of concrete plans for a Tibet-Xinjiang water diversion project, often dismissing reports as “untrue.” They sometimes point to other, more localized water diversion projects (like the Dianzhong water diversion project in Yunnan) as separate from a Tibet-Xinjiang scheme.

“Madcap” Schemes: Some experts have characterized certain proposals as “madcap schemes” that owe more to fantasy than science, emphasizing the immense practical and environmental obstacles.

Current Status:

While the concept of diverting water from Tibet to Xinjiang remains a topic of discussion and theoretical study, there is no confirmed large-scale project currently under construction or officially approved for diverting water directly from the Tibetan Plateau to Xinjiang on the scale of the “Hongqi River Project.”

China is undertaking other massive water diversion projects, such as the South-North Water Transfer Project, which moves water from the Yangtze River basin to drier northern regions, and localized projects like those diverting snowmelt from the Altai Mountains to northern Xinjiang, and efforts to restore the Tarim River. These are distinct from the highly ambitious and debated Tibet-Xinjiang grand diversion.

In conclusion, while the idea of diverting water from Tibet to Xinjiang is a long-standing ambition in China to address water scarcity, particularly through concepts like the “Hongqi River Project,” its immense technical, economic, environmental, and geopolitical challenges mean it remains largely in the realm of discussion and theoretical exploration rather than an active, approved construction project. https://www.facebook.com/jeff.mah.5/videos/1206463457354298/?__cft__[0]=AZWV-AIZCB7rRYQ49mcGQyCdvbCvGu0-z85Da2En5FjKMcq0h8avHq3ZDJwEuQjDAb2dY835mXsVt7BXyDuNCUakW4KzIMfdb1Yy0HHqxfOg9YjcNtpZO8iq5QCKBK8JEZFLCTe08XAfS_INM6tL0bCy07kS1ygjreWETKRptFzn9Q&__tn__=%2CO%2CP-R

Climate Ambition Summit

In a speech delivered on Saturday at the Climate Ambition Summit, Chinese President Xi Jinping made three proposals:

1. to close ranks and make new advances in climate governance that features cooperation and win-win;
2. to raise ambition and foster a new architecture of climate governance where every party does its part; and

3. to boost confidence and pursue a new approach to climate governance that highlights green recovery.

China will lower its carbon dioxide emissions per unit of GDP by over 65 percent from the 2005 level, and increase the share of non-fossil fuels in primary energy consumption to around 25 percent.
China will increase its forest stock volume by 6 billion cubic meters from the 2005 level, and bring its total installed capacity of wind and solar power to over 1.2 billion kilowatts

China says it aims to go carbon neutral by 2060

Chinese President Xi Jinping says China will aim to stop pumping additional carbon dioxide into the atmosphere by 2060.

Xi’s announcement during a speech Tuesday to the UN General Assembly is a significant step for the world’s biggest emitter of greenhouse gases and was immediately cheered by climate campaigners.

Calling for a green revolution, Xi said the coronavirus pandemic had shown the need to preserve the environment.

Humankind can no longer afford to ignore the repeated warnings of nature, he said.

Xi said his country would raise its emissions reduction targets with vigorous policies and measures. We aim to have CO2 emissions peak before 2030 and achieve carbon neutrality before 2060.
中国将提高国家自主贡献力度,采取更加有力的政策和措施,二氧化碳排放力争于2030年前达到峰值,努力争取2060年前实现碳中和。
