    An approach to maximising marine benefits
    (2018-06-20)
    Marine Protected Areas (MPAs) have been identified as useful tools globally to fulfil multiple objectives. The benefits of MPAs are well established in the management of fisheries, biodiversity and the tourism sector which rely on well preserved natural features. South Africa is currently in a process of declaring a new representative Marine Protected Area network that increases mainland marine territory protection from 0.42% to 5% towards its national and international target commitment of 10% protection by 2020. Further MPA expansion will rely on an innovative approach to meeting conservation targets with minimal social cost. Thirty-five case studies across 19 countries, 22 from developing and 13 from developed countries, were assessed to identify categories of non-consumptive benefits. The study found the following categories of benefits of MPAs: a) economic, b) biodiversity, c) meeting conservation targets, d) fisheries sustainability, e) heritage, and f) climate change resilience. Categories of benefits guided the retrieval of data layers, such as tourism infrastructure, ecosystem protection level, fishing grounds and heritage sites, to be used in systematic conservation planning to identify areas most favourable to deliver benefits with least cost to communities. Marxan, an optimisation tool, will be used to achieve this.

    Identification of Potential Vulnerable Marine Ecosystems for integrated ocean use planning to improve fisheries and ocean management
    (2018-06-20) Atkinson, Lara
    In 2006 the United Nations (UN) called on states to implement measures to prevent significant adverse impacts to Vulnerable Marine Ecosystems (VMEs) in the deep sea. Potential VMEs are identified by biological characteristics that express the vulnerability of their species, communities, and/or habitats to damage or disturbance. It is widely recognised that a major limitation to the effective management and protection of these fragile ecosystems is the uncertainty in their distribution. This study followed a multidisciplinary approach to identify potential VMEs in South Africa. We applied the 2009 Food and Agriculture Organization of the UN scientific guidelines for identifying VMEs, drawing from available national datasets including bathymetric, geological, fisheries and biodiversity data. Eleven potential VME habitat types were identified, including features likely to host VMEs and potential VMEs identified from indicator taxa. Twenty-two potential indicator taxa were identified using museum records and eight years of invertebrate trawl bycatch data. In addition, more than 350 visual surveys were analysed to identify potential VMEs. These approaches show how limited data can readily be applied to advance identification of potential VMEs. This work will support integrated ocean use planning efforts, sustainable fisheries management and aid industry to meet international fisheries ecocertification conditions.
