    Social-ecological vulnerability of coral reef fisheries to climatic shocks 2013
    Also available in:
    No results found.

    This circular examines the vulnerability of coral reef social-ecological communities to one effect of climate change, coral bleaching. The objective was to develop and test in Kenya a community-level vulnerability assessment approach that incorporated both ecological and socio-economic dimensions of vulnerability in order to target and guide interventions to reduce vulnerability. In addition to a range of direct threats such as siltation, overfishing and coral disease, coral reefs are now threat ened by climate change. Climate impacts on coral reefs and associated fisheries include: increasing seawater temperatures; changes in water chemistry (acidification); changes in seasonality; and increased severity and frequency of storms, which affect coral reef ecosystems as well as fisheries activities and infrastructure. Coral bleaching and associated coral mortality as a result of high seawater temperatures is one of the most striking impacts of climate change that has been observed to date. As warming trends continue, the frequency and severity of bleaching episodes are predicted to increase with potentially fundamental impacts on the world’s coral reefs and on the fisheries and livelihoods that depend on them. The analysis presented in this circular combined ecological vulnerability (social exposure), social sensitivity and social adaptive capacity into an index of social-ecological vulnerability to coral bleaching. All three components of vulnerability varied across the sites an d contributed to the variation in social-ecological vulnerability. Comparison over time showed that adaptive capacity and sensitivity indices increased from 2008 until 2012 owing to increases in community infrastructure and availability of credit. Disaggregated analysis of how adaptive capacity and sensitivity varied between different segments of society identified the young, migrants and those who do not participate in decision-making as having both higher sensitivity and lower adaptive capacit y and, hence, as being the most vulnerable to changes in the productivity of reef fisheries.

    An Acoustic Approach to Resource Mapping of Pulau Payar’s Coral Reef - BOBP/REP/87 2000
    Also available in:
    No results found.

    This document discusses the rationale, the conduct and the results of a new approach — the hydro-acoustic method — tried out to map the reef substrate of four islands at Pulau Payar Marine Park, Kedah state, Malaysia. The decision to adopt the method was taken after an October 1997 workshop held under the Special Area Management Plan of the Pulau Payar project, with support from the Bay of Bengal Programme (BOBP). A private company carried out the reef mapping exercise, whose objective was to document the diversity of coral growth forms at Pulau Payar, map and quantify coral resources, and prepare an update on the coral reef status at Pulau Payar, assessing any damage to the reef. The exercise was carried out in view ofthe plans by the Department of Fisheries, Malaysia, to inventory all the reefs in the country’s islands. Over the years, coral survey techniques have depended heavily on the SCUBA method which is considered risky, time-consuming and costly. Further, i t is impossible to produce a broadscale map with the SCUBA diving method. The author believes that the “new, repeatable and non-destructive hydro-acoustic survey approach” heralds a new era in corat studies.

    Amélioration de la gestion des récifs coralliens et de la pêche aux Comores, au Kenya, à Madagascar, à Maurice et aux Seychelles - GCP/RAF/520/JPN 2023
    Also available in:

    Les petits États insulaires en développement, mais aussi les pays côtiers continentaux d’Afrique de l’Ouest sont dotés de vastes récifs coralliens. Ces écosystèmes fragiles sont menacés par le changement climatique, la dégradation des récifs, l’extraction de sable, la surpêche et la pêche illicite, non déclarée et non réglementée (INDNR). Cette situation compromet la préservation des ressources halieutiques et entraîne une baisse des captures et des revenus pour de nombreuses communautés de pêcheurs qui en dépendent. Le projet visait à renforcer la gestion et la conservation des récifs coralliens et de leurs pêcheries afin d’améliorer l’état des ressources halieutiques dans les pays cibles, de stopper la tendance à la baisse de la production et de garantir des pêcheries durables à long terme ainsi que des communautés résilientes.
