Microbenthos and macrobenthos were quantitatively studied at 62 stations distributed regularly over the Uvea Atoll lagoon (850 km2). Sampling was performed using both SCUBA and a 0.1 m2 Smith Mclntyre grab. Mean estimates of ATP, chlorophyll a and phaeopigments were 297.3ng/cm2, 77.01 mg/m2 and 35.28 mg/m2 respectively. The mean macrobenthic biomass was 4.14 gAFDW/m2 of which the macrophytobenthos accounts for 39%. The benthic biomass decreased from the coast to the deepest parts of the lagoon. Macrophytes were most abundant in the coastal area and became progressively scarcer with increasing depth. By comparison, sessile species dominated on hard substrates in intermediate and deep zones. The abundance of the surface-deposit feeder group, that dominated the trophic structure of zoobenthos (33% of the macrofauna biomass), could be explained by a microphytic biomass six times higher than macrophytobenthic one in terms of carbon. Carnivores (32%) were mainly represented by necrophagous species, and filter-feeders (27%) by bivalves. Herbivores were rare. Four main benthic communities were identified on the basis of their macrobenthic assemblages using a Detrended Correspondence analysis. They corresponded to (1) a coastal zone, with the highest mud percentage in sediments, (2) an intermediate zone, with moderate depth and dominated by hard substrates, (3) a back reef zone, with thick sand layers, and (4) a deep zone dominated by hard substrates. Relative distribution of the trophic groups varied according to the different zones and suggests distinct functional characteristics for the different benthic assemblages. From a biogeographic point of view, this study highlighted the richness of the Uvea Atoll lagoon in terms of benthic species and biomass, compared to other central Pacific atoll lagoons.

Secretariat of the Pacific Regional Environment Programme (SPREP) (SPREP) with financial assistance from the United Nations Environment Programme (UNEP)

1998
The Initial draft of this action strategy for environmental education and training in the pacific region 1999 – 2003 was developed by participants at the pacific regional conference for environmental education and training, held in suva, Fiji, from 29 June – 3 July, 1998. The conference was attended by more than 170 representatives of 21 of SPREP’s Island member countries/ Each country’s delegation comprised representatives from the education department, environment department and a non- governmental organization. Representatives of regional and international organizations also contributed significantly, both as participants and as sponsors. The conference, co-hosted by the University of the South Pacific (USP), Pacific Resources for Education and Learning (PREL) and the south pacific regional environment programme (SPREP), funded by the Australian agency for international development (AusAID), New Zeeland official development assistance (NZODA), the Danish international development Agency (Danida) and the united kingdom’s Department for international development pacific (Dfid),provided a valuable opportunity for environmental educators and trainers from the pacific to link together, share experiences and determine how best to strengthen environmental education and training for the pacific islands region
