Biodiversity

The AA aims to avoid and minimise adverse impacts on biodiversity related to the development and operation of HKIA.

The Airport Authority (AA) recognises that the development and operation of Hong Kong International Airport (HKIA) can impact biodiversity and natural ecosystems around the airport. The AA is committed and has a duty of care to avoid, minimise and mitigate identified and potential impacts. A range of biodiversity conservation and enhancement initiatives are being implemented as part of its long-term efforts to protect and enhance the varied habitats and environments around HKIA.

Our Story

Marine Ecology and Fisheries Enhancement Strategy

Marine Ecology and Fisheries Enhancement Strategy

The Marine Ecology and Fisheries Enhancement Strategy (MEFES) comprises both statutory and voluntary initiatives for enhancing marine ecology and fisheries resources. Initiatives are either implemented directly by the AA, or comprise a range of projects supported by the Marine Ecology Enhancement Fund (MEEF) and the Fisheries Enhancement Fund (FEF).

Marine Ecology Enhancement Fund and Fisheries Enhancement Fund

In late 2016, the AA established the MEEF and FEF with a total budget of HK$400 million. These funds, run by independent management committees, aim to enhance the marine environment for the benefit of marine ecology and fisheries resources.

Since the establishment of the funds, over HK$55 million (as of August 2021) has been granted to support marine ecology and fisheries projects. Funded projects are typically managed and carried out by universities, research organisations, and fisheries industry associations.

Examples of funded projects include:

 

Proposed North Lantau Marine Park

Proposed North Lantau Marine Park

The Agriculture, Fisheries and Conservation Department has been taking forward the statutory procedures for the designation of the proposed North Lantau Marine Park (NLMP) which is primarily a mitigation measure for marine habitat impacted by the Three-Runway System (3RS) Project. The 2,400 hectares of the NLMP will connect with the existing and adjacent marine parks to form a combined marine park matrix of about 4,500 hectares. The interconnected protected area is expected to provide positive and synergistic effects for the conservation of marine ecology including the Chinese White Dolphins (CWDs) and fisheries resources.

Voluntary Enhancement Measures

The AA is also implementing a number of marine ecology and fisheries enhancement projects in Lantau waters on a voluntary basis under the MEFES.

Artificial Reef (AR) Deployment Pilot Test

About 100 AR units were deployed in waters to the west of HKIA’s South Runway in 2021. The ARs deployment serves as a pilot scheme to investigate the value of providing micro-marine habitats for enhancing marine ecology and fisheries resources in the vicinity of the proposed NLMP and its surrounding waters. The findings of this pilot will be studied for the potential additional deployments of ARs in North Lantau waters.

Shellfish Reef Deployment Pilot Study

In partnership with The Nature Conservancy and the University of Hong Kong, the AA has deployed oyster reefs, using a combination of limestone, recycled shells and live oysters, along a northeastern section of the 3RS’s newly formed seawall in 2021. This pilot aims to recreate a natural habitat that may promote proliferation of shellfish and other marine life in the area.
