This paper reviews the interactions between water supply, surface water quality, environmental management and sustainable development in the Pearl River Delta. As an economic center of the Pearl River Delta, Hong Kong has to import about 80 % of its potable water from Dongjiang. Ironically, the factories, which are invested by Hong Kong residents are believed to be one of the major sources of water pollution to Dongjiang. The present paper critically reviews this dilemma, and suggests practical solutions for achieving the 'win-win' scenario in water resource management and sustainable development in the 21st Century.

Water pollution can be monitored through the use of indicator species, including Brachionus calyciflorus. To do this, it is necessary to understand the species’ population ecology. Four surveys of zooplankton were conducted in May, August, and December 2018 and February 2019 in the Pearl River Delta, China, to examine the population characteristics of B. calyciflorus. The temporal and spatial distribution of abundance, biomass, dominance, and occurrence frequency were compared with those from 2012 to investigate the relationship between changes in the population of B. calyciflorus and environmental factors. The average abundance, dominance, and occurrence of B. calyciflorus in this survey were significantly higher than those of 2012 in all seasons. Principal component analysis showed that environmental factors such as the temperature, transparency, total nitrogen, and total phosphorus of water had a major impact on the abundance of B. calyciflorus. There was a significant positive correlation with transparency, total nitrogen, and total phosphorus of water, and a very significant positive correlation with water temperature. Overall, these results demonstrated that the distribution characteristics of B. calyciflorus can reflect pollution in water bodies and can be used to evaluate water quality. These research results provide a reference for evaluating China’s river health and can help to manage water quality in the Pearl River Delta.

AbstractThis paper explores how the government of the People's Republic of China (PRC) has been trying to incorporate post-1997 Hong Kong into the framework of a Greater China. The construction of two ‘narratives’ are examined: the grand narrative of Chinese history in secondary school textbooks in Hong Kong; and the development of a new regional framework of the Pearl River Delta. The first narrative, which focuses on the past, signals the PRC government's desire to inculcate through education a deeper sense of collective identity as patriotic citizens of China amongst residents of Hong Kong. The second narrative, which represents a futuristic imagining of a regional landscape, rewrites the trajectory of Hong Kong by merging the city with the Pearl River Delta region. However, these narrative strategies have triggered ambivalent responses from people in Hong Kong, especially the generations born after 1980. In their discursive battles against merging with the mainland, activists have sought to instil a collective memory that encourages a counter-imagination of a particular kind of Hong Kong that draws from the pre-1997 past. This conflict pits activists and their supporters against officials in the local government working to move Hong Kong towards integration with greater Guangdong and China at large. But the local resistance discourses are inadequate because they are constrained by their own parochial visions and colonial nostalgia.

Following the return of Hong Kong to Chinese jurisdiction in 1997, there has been concern about the potential marginalization of Hong Kong within China's development. We argue that far from being marginalized, Hong Kong together with the Pearl River Delta is becoming the most dynamic region within China.
