HKD 4.3M Grants Won for Tolo Harbor (吐露港) Biodiversity & Ecology Research

More than 25 local marine biologists have been awarded a grant that will enable them to study the marine biodiversity and ecology of the Tolo Harbour and channel.

Tolo Harbor is a semi-enclosed body of water in the northeast of Hong Kong linked to the sea only by the narrow Tolo Channel. The Tolo Channel and Harbor were infamous in the 1980’s for terrible water pollution, fould smells and red tides. A rapid expansion of urban areas on the firnge of Tolo Harbor with direct, untreated sewage discharges into the Harbor caused large scale eutrophication. The sewage outfalls provided nutrients feeding massive algal blooms which subsequently died and their decomposition by microorganisms used up so much oxygen that the water and sediment became anoxic, killing fish and many other marine organism (again feeding oxygen demand form decomposition) and causing foul smelling water. The problem was made much worse because Tolo Harbor is not very well flushed with new oxygenated water from the sea. It was eventually improved by providing proper modern sewage treatment and recognizing the particular vulnerablility of the area to eutrophication.

The HK$4.3 million will benefit the Joint University Consortium for Biodiversity, Ecology and Conservation of Marine Ecosystems and comes via the Environment and Conservation Fund (ECF). The ECF was established by the government in 1994 as part of its long-term commitment to environmental protection and conservation and received an injection of $5 billion in 2013, to serve as seed money generating an annual investment returns to support green projects and activities. The ECF has so far funded over 4,290 educational, research, and other projects and activities in relation to environmental and conservation matters.

Despite the funding being delayed for about two years, the proposal was approved last month and the 18-month project will commence later this year. The first stage of the two-phase study is aimed at finding the current ecological status of the area as well as the economic value of marine resources. The team will establish a comprehensive species database of the area. Kevin Ho King-yan, a senior research assistant at the School of Biological Sciences at the University of Hong Kong, said the proposal was aired at least two rounds of interviews, possibly because of the large amount of money required.

“Usually, project funding proposals to the conservation fund average around the hundred thousand mark, but this time it is in the millions,” he said. The announcement comes after an international conference, jointly organized by the Swire Institute of Marine Science and the University of Hong Kong School of Biological Sciences, kicked off at HKU yesterday.

More than 280 participants from 26 countries have come together for the four-day conference to discuss issues such as coastal development and marine conservation. More than 20 marine scientists from overseas and the mainland are attending. Organizing committee chairman Kenneth Leung Mei-yee said experts from across the globe need to work together to map out a plan to protect marine biodiversity. “We need experts from all different sectors to join hands together to uncover what we have and how we can protect them and how we can make sustainable use of these resources,” Leung said.

Note: The Hoi Ha Wan marine park – noted for its corals – is located at the seaward mouth of the Tolo Channel.
