In 2011, a group of Hong Kong water activists and researchers travelled the length of the Dongjiang (East) River, which stretches from north-east Guangdong province into Hong Kong\u2019s New Territories, to investigate the challenges facing the watershed. The Dongjiang basin, which provides nearly 80% of Hong Kong\u2019s water supply, has suffered water shortages due to the region\u2019s increasing urbanisation and industrialisation. They found unchecked wastewater discharges \u2013 from agriculture, poultry farms, chemical plants, tanneries, and even an open-air quartz quarry \u2013 were dangerously degrading water quality.<\/p>\n

Six years later, a delegation from the Hong Kong government retraced the journey, hoping to find that officials in neighbouring Guangdong had made improvements in water quality and conservation. During the 20 years since Hong Kong was handed over to mainland China, cooperation between Hong Kong and Guangdong on many environmental challenges has gained traction \u2013 with the notable exception of water management. Due to an unfavourable fixed price agreement between the neighbouring governments and a lack of sustainable supply, Hong Kong finds itself paying too much for too little.<\/p>\n

Uncooperative neighbours<\/strong><\/p>\n

Hong Kong and Guangdong\u2019s energy and environmental infrastructure are tightly intertwined. In addition to Hong Kong\u2019s dependence on water from the Dongjiang, concerns over cross-boundary air quality, energy, and food supplies strain the relationship between these two cities. Hong Kong relies on Guangdong nuclear power plants for as much as a quarter of its electricity, sparking fears of a major nuclear accident; air pollution from Guangdong\u2019s factories drifts into Hong Kong; and Hong Kong imports 95% of its food, a large portion of it from Guangdong.<\/p>\n

Guangdong, too, suffers from insufficient supplies and poor quality of water. When polluting industries \u2013 like textile dye plants or tanneries \u2013 have poured too much wastewater or too many chemicals in one area, local authorities are forcibly relocated to another part of the province, exporting the pollution to new areas. While there have been recent improvements in the watershed, growing cities and increasing industrial and agricultural development continue to lead to pollution from excessive use of heavy metals, organochlorine pesticides, PCBs, and wastewater discharges.<\/p>\n

Like Guangdong, Hong Kong has made modest efforts to improve its water quality and stretch its water supplies through innovative practices, such as utilising seawater for toilet flushing. However, the cross-boundary problems extend both ways. More than half of Guangdong\u2019s polluting businesses are financed by Hong Kong, including industries relocated inland during the 1980s. Similarly, when polluting agricultural activities were forced out of Hong Kong to reduce water runoff, the move simply increased water pollution problems in Guangdong \u2013 providing only momentary reprieve for Hong Kong, as the pollution eventually flows back across the border.<\/p>\n

The community value of water<\/strong><\/p>\n

The interconnections between Hong Kong and Guangdong prove that environmental issues that cross boundaries, like water quality, require an integrated management approach. Cross-border cooperation between China and Hong Kong should be significantly expanded, in the context of the \u201cone country, two systems\u201d relationship. However, the governments have made only a few joint efforts to address their water issues; a similar story has played out across China, where most upstream provinces are hostile to any overtures from downstream provinces to cooperate on water. Hong Kong participates in a few information exchanges and monitors waters from the Dongjiang at its own intake facilities, but has no formal role in directly addressing quality and supply of the water, which is increasingly coveted by other fast growing cities in Guangdong.<\/p>\n

An effective demand management approach \u2013\u00a0recognising that water is a scarce resource and focusing on how it is used rather than on obtaining new supplies \u2013 is key for both Hong Kong and Guangdong. Sharing best practices of efficient water usage, pollution control, and water recycling would help stretch scarce supplies. Hong Kong\u2019s new wastewater-to-energy plant, which doubles as a recreation and education centre, could be a valuable model to share with its counterparts in Guangdong and other cities in China, where few wastewater plants capture methane to generate electricity because of numerous market and policy obstacles and low levels of organic material in the water from excessive storm water runoff.<\/p>\n

Combining this demand-side approach with the sustainable management of watersheds would help bolster a new type of water ethic for both Hong Kong and Guangdong that focuses on the community value of water rather than its commodity value. Greater input from community stakeholders (potentially though a Watershed Council) could help governments identify both the sources of \u2013 and potential solutions to \u2013\u00a0environmental problems that would benefit all of the people dependent on a watershed. Environmental protection across political borders necessitates a close relationship between people and places, democratic participation, and a new community-based ethic that values meeting the needs of people and the environment.<\/p>\n
