South-to-North Water Diversion Project's Central Route Marks Three Years of Transformative Operations, Reshaping Landscapes and Livelihoods

Tuesday, December 12, 2017, marked a significant milestone for China, as the central route of its colossal South-to-North Water Diversion Project celebrated its third anniversary of full operation. This ambitious infrastructure endeavor, designed to alleviate chronic water scarcity in the arid northern regions by redirecting vital water resources from the country’s south, has already demonstrated profound impacts, delivering over 10 billion cubic meters of water and benefiting more than 53 million people across North China. Beyond its primary function of water supply, the project has inadvertently spurred an environmental renaissance in its source regions, fostering green industries and creating sustainable economic opportunities for local communities.

A Lifeline to the Arid North: The Central Route’s Unprecedented Impact

The central route, a critical component of China’s grand strategy for water security, originates from the Danjiangkou Reservoir on the Han River, a major tributary of the Yangtze. Spanning over 1,200 kilometers, this engineering marvel traverses Henan and Hebei provinces before reaching its termini in Beijing and Tianjin. Since its commissioning, the volume of water transferred has steadily increased, providing a crucial lifeline to cities and agricultural areas grappling with dwindling groundwater reserves and increasing demand.

Recipient cities like Beijing and Tianjin, historically plagued by severe water shortages and over-extraction of groundwater, have seen tangible improvements. In Beijing, the central route has become a primary source of potable water, significantly reducing reliance on local groundwater and surface sources. Official data indicates that by its third anniversary, the central route alone supplied approximately 70% of Beijing’s urban water supply and 90% of its main urban area’s water, translating to billions of cubic meters that have helped stabilize groundwater tables and improve the quality of life for millions. Tianjin, another major northern metropolis, has similarly benefited, receiving a substantial portion of its municipal and industrial water needs from the project, thereby supporting its economic development and ecological restoration efforts. The provinces of Henan and Hebei, through which the canal passes, have also tapped into the transferred water for both urban consumption and agricultural irrigation, contributing to regional food security and ecological health.

A Grand Vision: The Genesis of the South-to-North Water Diversion Project

The concept of diverting water from China’s water-rich south to its parched north is not new; it dates back to the 1950s when Chairman Mao Zedong famously declared, "The south has plenty of water, the north lacks it. If possible, borrow some." This vision was born out of a stark geographical imbalance: the Yangtze River basin and areas south of it account for roughly 80% of China’s water resources, while the Yellow River basin and northern regions, home to a significant portion of the country’s population and agricultural land, possess only about 20%. This disparity, exacerbated by rapid industrialization, urbanization, and agricultural expansion, led to severe water stress, ecological degradation, and socio-economic challenges in the north.

Decades of planning, feasibility studies, and debates followed Mao’s pronouncement. The immense scale and complexity of the project, coupled with its potential environmental and social impacts, required meticulous consideration. The overarching goal was to create a robust national water network, not only to supply water but also to improve ecological conditions, facilitate economic growth, and enhance national water security.

Engineering Marvel: An Overview of the Three Routes

The South-to-North Water Diversion Project is conceived as a multi-decade, multi-route undertaking, ultimately comprising three main canals: the Eastern, Central, and Western routes.

The Eastern Route: Utilizing the ancient Grand Canal system, this route draws water from the lower reaches of the Yangtze River near Yangzhou, Jiangsu province. It uses a series of pumping stations to lift water northward through Jiangsu and Shandong provinces, eventually supplying areas including Tianjin and parts of Hebei. Its first phase became operational in 2013, primarily serving Shandong and Tianjin.
The Central Route: The focus of the current anniversary, this route is considered the most strategically important due to its gravity-fed design and direct supply to the capital, Beijing. It begins at the Danjiangkou Reservoir, where the Han River (a Yangtze tributary) meets the Qinling Mountains. The water flows through an open canal, tunnels, and aqueducts, requiring minimal pumping due to careful elevation management. This route necessitated significant dam raising at Danjiangkou and extensive resettlement, particularly in Hubei and Henan provinces.
The Western Route: Still in its planning and feasibility study stages, this is the most challenging and ambitious of the three. It aims to divert water from the upper reaches of the Yangtze River’s tributaries on the Qinghai-Tibet Plateau, across high mountain ranges, to the Yellow River basin. This route faces formidable engineering and environmental hurdles due to the extreme terrain and sensitive ecosystems.

Revitalizing Source Regions: A Green Transformation

While the primary objective of the project is to supply water to the north, its indirect consequences for the source regions—specifically Henan, Hubei, and Shaanxi provinces—have been equally transformative. To ensure the quality of water flowing northward, stringent environmental protection measures were implemented across the catchment areas of the Danjiangkou Reservoir and its feeder rivers. These measures included closing polluting factories, promoting ecological farming practices, reforestation, and investing in wastewater treatment facilities.

Water diversion project drives environmental improvements and provides new jobs for locals

The stringent environmental mandates initially posed economic challenges for some local communities reliant on traditional industries. However, the long-term benefits have begun to emerge. The cleaner environment, healthier ecosystems, and improved water quality have become powerful magnets for investment in "green industries." Ecotourism, sustainable agriculture, and aquaculture, which rely on pristine natural conditions, have flourished. For instance, the image showing residents strolling through Ankang city in Shaanxi province underscores the improved livability and environmental quality in these areas. The cleaner air and water have not only enhanced local quality of life but also rebranded these regions as attractive destinations for both tourists and environmentally conscious businesses.

The Human Dimension: Returning Home to a Greener Future

The story of Xia Qinghua, a 43-year-old from Chenjiawan village in Hubei’s Shiyan city, perfectly encapsulates this profound transformation. For 12 years, Xia worked in a small toy factory in Shenzhen, Guangdong province, like millions of other migrant workers drawn to the economic opportunities of China’s coastal manufacturing hubs. His monthly salary of over 5,000 yuan ($756) was substantial, but it came at a personal cost: long working hours, often until 11 pm, and a gnawing sense of loneliness and isolation from his family.

Xia’s desire to return home was constant, but the economic realities of his poverty-stricken hometown presented a formidable barrier. In 2011, he attempted to establish a transportation business with a 50,000 yuan investment in a small truck, but the lack of opportunities led to a 20,000 yuan debt and forced his reluctant return to Shenzhen. For years, his family separations were tearful affairs, particularly during the annual Spring Festival holiday. He vividly recalled a heartbreaking departure on the fifth day of the Lunar New Year in 2013, where he, his wife, and daughter cried in each other’s arms, a testament to the emotional toll of economic migration.

However, the tide began to turn in 2014, when Hubei Beidouxing Eco-agriculture and Forestry Co began investing in Chenjiawan, directly lured by the "great improvements" in the local environment. "When I left at age 17, I had never seen an egret. Now, there are birds everywhere. They are beautiful," Xia recounted, highlighting the visible ecological recovery. This environmental regeneration created new, sustainable job opportunities that were previously nonexistent.

In June 2017, Xia finally realized his long-held dream, returning to Chenjiawan to work in the warehouse of a Hubei Beidouxing farm. Although his current monthly income of approximately 2,000 yuan is significantly less than what he earned in Shenzhen, Xia expresses profound happiness. He is now close to his family, able to care for his unwell 70-year-old father, and supplements his income by leasing 0.5 hectares of farmland to Hubei Beidouxing, earning an additional 4,000 yuan annually. His story is a powerful illustration of how environmental protection, driven by national infrastructure projects, can foster local economic development and enable family reunification, improving overall quality of life.

Economic Ripples: Investment and Opportunity in the Supply Zones

The success of companies like Hubei Beidouxing Eco-agriculture and Forestry Co is emblematic of a broader trend in the source regions. The commitment to water quality has necessitated a fundamental shift from heavy industry and pollution-intensive agriculture to eco-friendly alternatives. Local governments, in cooperation with national environmental agencies, have actively promoted policies that attract investment in sectors such as:

Ecotourism: The improved natural landscapes, including pristine rivers, forests, and now abundant wildlife, have made these areas attractive for domestic and international tourists. This has led to the development of guesthouses, nature reserves, and related service industries.
Organic and Ecological Agriculture: With guaranteed clean water and healthier soils, farmers are transitioning to high-value organic produce, specialty crops, and aquaculture, commanding higher market prices and creating more stable incomes. This includes products like high-quality teas, fruits, and fish.
Forestry and Reforestation: Extensive reforestation efforts, aimed at soil and water conservation, have created jobs in planting, maintenance, and sustainable timber harvesting, as well as associated forest products.
Renewable Energy: Some areas have seen investment in solar and wind farms, aligning with the broader green development strategy.

These investments have not only created direct employment but also stimulated local economies through increased demand for services, infrastructure development, and improved local supply chains, benefiting residents like Xia Qinghua and countless others.
