China is at the centre of Asia’s struggle for water security
At the recent COP27 climate conference in Egypt, water security was high on the agenda. One country that has long understood the value of water is China. In many ways, China’s history is one of water management. It is said that the unique hydrological conditions within China led to the creation of three historical miracles: China, Chinese civilisation, and the Chinese people.
Currently, China faces enormous challenges related to water distribution; the densely populated north suffers from acute water shortages, whereas the south is prone to severe floods. Due to various factors like urbanisation, the demand for fresh water is quickly increasing. Forecasts project that, by 2030, China’s water demand will surpass 800 billion cubic metres.
However, the country’s water supply is severely undermined by interlinked factors of water scarcity, urbanisation, population growth, pollution, and competing water demands.
China’s approach to water management has traditionally been engineering-focused, as shown by the construction of many inter-basin transfer projects and hydropower dams.
Recent project proposals like the Red Flag River and the “super” dam suggest that this approach will continue in the future.
However, the environmental hydrosocial impacts of this approach are well established. Large-scale dams, in particular, are linked to biodiversity loss, soil erosion, forced displacement of local residents, and destruction of forests and wildlife habitats.
China, the “upstream superpower” of many of Asia’s longest and most important rivers and regional hydro-hegemon, does not have an independent transboundary river policy. Instead, the management of transnational water resources falls under the much broader framework of foreign relations.
Due to the potential geopolitical and hydropolitical repercussions, China’s dambuilding agenda has received much criticism. Hydropower dams can have an enormous impact on water supply by affecting river flow to the downstream region.
Chinese-built dams, constructed both within China and outside the country, have caused significant concern along with ecological, socioeconomic and environmental damage in downstream regions.
As many of China’s dams are built in Tibet on the upstream of major transnational rivers like the Brahmaputra – known in China as Yarlung Tsangpo – and the Mekong, there are fears in downstream regions over China’s potential ability to control the downstream flow. How might these regions’ access to water be affected?
Given China’s mistrust of the use of multilateral frameworks to resolve international disputes, Beijing has not signed any watersharing agreements with its neighbours. Some of China’s neighbours have not signed such agreements, either.
China is not the only nation being criticised for its dam building. Hydropower dam projects in India have similarly caused alarm among neighbouring countries. While India has accused China of harnessing the hydropower potential of transnational rivers for its own benefit, some argue that India has similar ambitions.
China faces severe repercussions from global warming, and water is one of its most vulnerable sectors. The seeming unwillingness of countries to address cross-border river sharing and related agreements will only exacerbate tensions.
Historical rivalries and power asymmetry between countries, combined with water scarcity and poor water management within countries, makes transboundary river governance even more challenging.
In this context, Beijing should consider becoming a regional leader by establishing equitable, effective and sustainable cross-border river mechanisms that promote cooperation between governments, scientists and academics across the riparian countries. Only then can China reduce water scarcity and related fears which have long exacerbated tensions between countries and throughout the region.
