At the recently held inception workshop, the WIO GCRMN benthic and fish datasets were identified as key datasets to undertake the 2019 Red List of Ecosystems of coral reefs of the Western Indian Ocean (see workshop report here). The GCRMN datasets were compiled with support from the Indian Ocean Commission’s 5-year […]
Disentangling drivers of the abundance of coral reef fishes in the western Indian Ocean This recent paper led by Melita Samoilys has just been published in Ecology and Evolution; her blog provides a synopsis. Climate change is an increasingly acute pressure on coral reefs and combined with fishing is changing […]
The Ocean Health Index (OHI) is a scientific framework used to measure how healthy oceans are. It is the first integrated assessment framework that scientifically combines key biological, physical, economic, cultural and social elements of the ocean’s health. The OHI scores reflect how well coastal regions optimize their potential ocean benefits and services in […]
The IUCN Red List of Ecosystems is a global framework for assessing the status of ecosystems. The assessment will kick-off with a planning and training workshop in Mombasa in March, after which the regional analysis and assessment will be carried out, concluding in September 2019 with a dissemination workshop.
The challenge The first complete assessment of reef-building corals was completed in 2008 (Carpenter et al. 2008) from which the Red List Index of corals shows the most significant decline of all taxonomic groups assessed (fig. below), due to the impact of the 1998 global coral bleaching event. Cost/investment We estimate […]
The Comoros islands are a poorly known volcanic chain of islands in between Mozambique and Madagascar in the ‘hotspot’ of coral reef biodiversity for the Western Indian Ocean. They still possess some beautiful areas of coral, but are threatened because of the combined effects of over-fishing, sedimentation from deforestation on land, coral […]
