Deteriorating quality of the coastal waters of the ASCLME region poses a significant threat to public health as well as to the health of its living marine resources and ecosystems – and thus also to the economy to which fisheries revenues, for example, contribute US$943 million annually (ASCLME). The sources of pollution which contribute to this deterioration include both land-based and marine and maritime related activities.

Many marine reef fish species have two distinct life stages: a larval pelagic stage lasting a few weeks followed by a benthic stage after recruitment (Dufour, 1992; Shima, 2001; McCormick et al., 2002; Lecchini & Galzin, 2003; Irisson et al., 2004). Larvae dispersal is a vital process for species evolution, genetic mixing and overall adaptation of reef fish populations (Caley et al., 1996; Shulman, 1998; Planes, 2002).

Restoring, maintaining and conserving the ecological integrity of the Agulhas Somali Current Large Marine Ecosystem (Figure 1) while ensuring optimal and sustainable utilization of the resources has been identified as a priority (Obura et al., 2012), especially with regard to the development of policy for the establishment of transboundary Marine Protected Areas (MPAs). This task requires knowledge of the spatial distribution of the physical and biological patterns and processes than sustain marine biodiversity in the region (Lombard et al. 2007; Sink and Attwood 2008).

The overall objective of this project is to develop specific spatial data products at regional scale, for the coastal and/or marine areas of all the western Indian Ocean countries, including South Africa, Mozambique, Tanzania, Kenya, Somalia, Comoros, Seychelles, Madagascar, Mauritius and France. This report summarizes the data products, which have been prepared, on the basis of their relevance to the Large Marine Ecosystems (LME’s). The preparation of these data products involved retrieval from various sources, spatial analysis and modelling, and scaling.

Invasive alien species (IAS) are now generally recognised as one of the greatest threats to global biodiversity. They also have serious economic, environmental and health impacts and, as a result, can place major constraints on development and natural resource use. In the marine realm there are examples of invasive species from all different taxonomic groups, ranging from plants, to vertebrates and even microbes.

Part A of this report examines the full range of regional environmental and resource management organizations in the Western Indian Ocean, outlining their competences and main areas of operation. It then looks at the range of environmental and resource management projects which are being, or have recently been, funded in the region, assessing their key objectives and outputs.
