  • Review and Renewal of the Ramsar Site Management Plan
    For discussion NCSC Paper 5/10 on 17 November 2010 Advisory Council on the Environment Nature Conservation Sub-committee Review and Renewal of the Ramsar Site Management Plan Purpose The purpose of this paper is to inform Members on the review and renewal exercise of the Management Plan for the Mai Po Inner Deep Bay Ramsar Site. Background 2. The Mai Po and Inner Deep Bay area was listed as a Wetland of International Importance (the Ramsar Site) under the Ramsar Convention on 4 September 1995. According to Article 3.1 of the Convention, “the Contracting Parties shall formulate and implement their planning so as to promote the conservation of wetlands included in the List (i.e. the Ramsar Sites)”. 3. In 1996, a study named “Development of a Comprehensive Strategy and a Management Plan in Relation to the Listing of Mai Po and Inner Deep Bay as a Wetland of International Importance under the Ramsar Convention” (the Ramsar Site Study) was implemented by the then Agriculture and Fisheries Department (renamed Agriculture, Fisheries and Conservation Department in 2000 (AFCD)) to produce the first Ramsar Site Strategy and Management Plan (RSMP). The RSMP laid down the general framework of management zoning and outlined management programmes for the long-term conservation and wise-use of wetlands for the Ramsar Site. The government adopted the RSMP for implementation in 1998 and has regularly reviewed the management programmes and issues of concern since then. 4. One of the major components of RSMP is the management zoning scheme of the Ramsar Site. The scheme comprises five management zones, namely, Core Zone (CZ), Biodiversity Management Zone (BMZ), Wise Use 1 Zone (WUZ), Public Access Zone (PAZ), and Private Land Zone (PLZ).

  • For Discussion on 10 May 2021 Legislative Council Panel On
    LC Paper No. CB(1)855/20-21(06) For discussion on 10 May 2021 Legislative Council Panel on Development Report on Implementation Progress of Heritage Conservation Initiatives Purpose This paper updates Members on the latest position of the implementation of various heritage conservation initiatives since our last report to the Panel in April 2020. In particular, an update is provided on the progress of three Batch V projects under the Revitalising Historic Buildings Through Partnership Scheme (the “Revitalisation Scheme”), namely (1) Roberts Block, Old Victoria Barracks, (2) Luen Wo Market, and (3) Former Lau Fau Shan Police Station. The Panel’s support for the funding application for the above three projects is sought. Heritage Conservation Policy Policy statement 2. As promulgated in 2007, the Government seeks “to protect, conserve and revitalise as appropriate historical and heritage sites and buildings through relevant and sustainable approaches for the benefit and enjoyment of present and future generations. In implementing this policy, due regard should be given to development needs in the public interest, respect for private property rights, budgetary considerations, cross-sector collaboration and active engagement of stakeholders and the general public.” Statutory monument declaration system 3. In accordance with section 3 of the Antiquities and Monuments Ordinance (Cap. 53) (the “Ordinance”), the Antiquities Authority (i.e. the 1 Secretary for Development) may, after consultation with the Antiquities Advisory Board (“AAB”) and with the approval of the Chief Executive, by notice in the Gazette, declare any place, building, site or structure, which the Authority considers to be of public interest by reason of its historical, archaeological or palaeontological significance, to be a monument.
