  • Motion 2- RAMSAR Listing Menindee Lakes.Pdf
    Motion 2 Region 4 – Central Darling Shire Council Motion: That the MDA calls on Basin Governments to endorse the Menindee Lakes, or a portion of the Lake system to be listed as a Ramsar site, in further consultation with the community. Objective: To protect the Menindee Lakes as a wetlands of cultural and ecological significance and to preserve and to conserve, through wise use and management, those areas of the system identified as appropriate for listing. Key Arguments: • In 2010-11 there were attempts to have a proportion of the Menindee Lakes recognised as being listed as a Ramsar site. Regional Development Australia Far West NSW (RDAFW) invested resources and efforts into having a proportion of the Lakes listed as a Ramsar Sites on behalf of Central Darling Shire and the Far West region. At this point in time, the State Government recognised the significance of the Menindee Lakes, however they were not able to support the project with the position of the Murray Darling Basin plan at the time. • Ramsar Convention and signing on Wetlands took place on 2 February 1971 at the small Iranian town named Ramsar and came into force on 21 December 1975. Since then, the Convention on Wetlands has been known as the Ramsar Convention. The Ramsar Convention's intentions is to halt the worldwide loss of wetlands and to conserve, through wise use and management, of those that remain. This requires international cooperation, policy making, capacity building and technology transfer. • Under the Ramsar Convention, a wide variety of natural and human-made habitat types ranging from rivers to coral reefs can be classified as wetlands.

    Ramsar wetland management in Australia 16 / Wetlands Australia February 2014 Ramsar in New South Wales – a tale of 12 sites New South Wales Office of Environment and Heritage While Dickens wrote about only two places in his ‘Tale of Two Cities’, New South Wales can tell a tale of 12 unique sites protected under the Ramsar Convention. e 12 Ramsar sites in NSW cover a range of climatic e NSW Government has committed, through zones and landscapes found in the state. ese unique intergovernmental agreements and partnerships, to wetland environments include icy cold alpine lakes in provide for the protection, sustainable use and the Snowy Mountains, extensive mangrove forests in management of all NSW wetlands, including Ramsar the mouth of the Hunter River near Newcastle, broad wetlands. Water availability is the primary pressure on river red gum forests on the inland oodplains of the Macquarie and Murray rivers, and even the occasionally inundated Lake Pinaroo in the state’s harsh and arid north western corner near Tibooburra. e tale begins with Towra Point Nature Reserve on Sydney’s doorstep and the Hunter Estuary Wetlands near Newcastle’s busy ports, both were designated as NSW’s rst Ramsar sites on the same day in 1984. Both wetlands feature extensive areas of mangroves and saltmarsh and provide critical habitat for up to 34 species of migratory birds and many sh species.

National Reports should be sent to: Alexia Dufour, Regional Affairs Officer, Ramsar Secretariat ([email protected]) National Report Format for Ramsar COP11, page 2 Introduction & background 1. This National Report Format (NRF) has been approved by the Standing Committee in Decision SC41-24 for the Ramsar Convention’s Contracting Parties to complete as their national reporting to the 11th meeting of the Conference of the Contracting Parties of the Convention (Bucharest, Romania, June 2012). 2. Following Standing Committee discussions at its 40th meeting in May 2009, and its Decision SC40-29, this COP11 National Report Format closely follows that used for the COP10 National Report Format, which in turn was a significantly revised and simplified format in comparison with the National Report Formats provided to previous recent COPs. 3. In addition to thus permitting continuity of reporting and implementation progress analyses by ensuring that indicator questions are as far as possible consistent with previous NRFs (and especially the COP10 NRF), this COP11 NRF is structured in terms of the Goals and Strategies of the 2009-2015 Ramsar Strategic Plan adopted at COP10 as Resolution X.1, and the indicators

  • Framing Effects and Benefit Transfer in the Fitzroy Basin
    Framing effects and benefit transfer in the Fitzroy basin John Rolfe * Adam Loch * Jeff Bennett** Paper presented at the 46th Annual Conference of the Australian Agricultural and Resource Economics Society 13th – 15th February 2002 Rydges Lakeside Hotel Canberra, Australian Capital Territory * Faculty of Business and Law, Central Queensland University, Emerald QLD 4720 * Faculty of Business and Law, Central Queensland University, Emerald QLD 4720 ** National Centre for Development Studies, Australian National University, Canberra. Abstract. Policy makers are often interested in how estimates of the value of an environmental asset may be disaggregated into component pieces. This is particularly the case when they are seeking to transfer benefit estimates made in one situation to related circumstances. This is the case for the environmental values of the Fitzroy River basin in Central Queensland. The basin comprises several smaller catchments that share similar development opportunities, environmental issues and water resource constraints. This paper describes an application of the choice modelling technique to estimate values for the basin as a whole and two of the smaller catchments to determine how values may be related. Comparisons are undertaken to assess the validity of the choice modelling approach to benefit transfer issues in environmental valuation studies. Keywords: Choice modelling, framing, benefit transfer, irrigation, environment. 2 1. Introduction Within the framework of environmental valuation the need often arises to apply values estimated for an environmental good in one context to another similar context. This process is called benefit transfer (BT). Boyle and Bergstrom (1992:657) state that benefit transfer is ‘the transfer of existing estimates of non-market values to a new study which is different from the study for which the values were originally estimated’.

  • Threatened Species Scientific Committee's Advice for the Wetlands and Inner Floodplains of the Macquarie Marshes
    Threatened Species Scientific Committee’s Advice for the Wetlands and inner floodplains of the Macquarie Marshes 1. The Threatened Species Scientific Committee (the Committee) was established under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and has obligations to present advice to the Minister for the Environment, Heritage and Water (the Minister) in relation to the listing and conservation of threatened ecological communities, including under sections 189, 194N and 266B of the EPBC Act. 2. The Committee provided this advice on the Wetlands and inner floodplains of the Macquarie Marshes ecological community to the Minister in June 2013. 3. A copy of the draft advice for this ecological community was made available for expert and public comment for a minimum of 30 business days. The Committee and Minister had regard to all public and expert comment that was relevant to the consideration of the ecological community. 4. This advice has been developed based on the best available information at the time it was assessed: this includes scientific literature, government reports, extensive advice from consultations with experts, and existing plans, records or management prescriptions for this ecological community. 5. This ecological community was listed as critically enadangered from 13 August 2013 to 11 December 2013. The listing was disallowed on 11 December 2013. It is no longer a matter of National Environmental Significance under the EPBC Act. Page 1 of 99 Threatened Species Scientific Committee’s Advice:
