Publication contains a fisheries-oriented discussion of macroeconomics, country information on specific topics (fisheries production, contribution to GDP, etc), a discussion of important topics across all countries, some important features of the benefits from fisheries that have emerged from this study, and recommendations on improving the measurement of fisheries benefits and assuring the continuity of those benefits.
The economic contribution of fisheries to the economies of Pacific Island nations.
Survey of echinoderm diversity in Nauru. 18 species of echinoderms, most of them new records for the island. A total of 24 species of echinoderms are now known from Nauru. Six holothuroids (sea cucumbers), five echinoids (sea urchins), five asteroids (sea stars), five ophiuroids (brittle stars) and three crinoids (feather stars)
Coral reefs in the Southwest Pacific are generally in good condition. There was extensive
coral bleaching during 2000-2002. Since then coral reefs have shown highly variable recovery
with some reefs recovering fully to pre-bleaching levels of live coral cover, whereas others
have shown virtually no recovery. Nauru experienced coral bleaching and mass fish kills in
October-December 2003, possibly due to unusually high sea surface temperatures. The greatest
threats to coral reefs of the region continue to be human activities and cyclones, with reefs
Synthesis of the state of marine resources in Nauru, specifically coral reef biodiversity, fauna and flora and the threat to these resources.
The current fishery characterisation includes updates to historical data, which show that 2019 was the
highest catch year in history, with catches of the four target tuna species just under 3 million tonnes (t).
We expect revisions to the 2019 catch estimates in next year's report, as estimates in the most recent
year are preliminary.
Six survey methods were applied to suit the different coastal habitats of Nauru. These were reef benthos
transects, reef front timed walks at night, manta tow, reef front timed swims in the daytime, lobster night
searches (reef front timed swims at night) and deep-water timed scuba searches. Where possible, information
from this assessment was compared with that collected during the PROCFish survey in 2005, to explore
changes in resource status over time.
The nature of shallow aquifers and the impacts of seawater intrusion in small islands within the Pacific Ocean are reviewed. Many Pacific islands rely on shallow fresh groundwater lenses in highly permeable aquifers, underlain and surrounded by seawater, as their principal freshwater source. It is argued here that, in small islands, the nature of fresh groundwater lenses and their host aquifers coupled with frequent natural and ever-present anthropogenic threats make them some of the most vulnerable aquifer systems in the world.
Water resources sustainable management is a vital issue for small islands where groundwater is often the only available water resource. Nauru is an isolated and uplifted limestone atoll island located in the Pacific Ocean. Politecnico di Milano performed a feasibility study for the development of sustainable use of groundwater on the island. This paper focuses on the first phase of the study that concerns the conceptual site model development, the hydrogeological characterization and the 2D model implementation.
The vegetation and flora of Nauru are among the most impoverished, degraded, disturbed and displaced in the Pacific islands. Long habitation, almost a century of opencast phosphate mining, continuous bombing, destruction and displacement of the people during World War 11, rapid urbanization and the abandonment of agriculture and subsistence activities have arguably produced one of the most severely modified nautral and and cultural floras on earth.
The indigenous floras of the raised phosphatic limestone island of Nauru and the atolls of the Gilbert Islands are among the poorest on earth. Long settlement, widespread destruction during World War II, monocultural
expansion of coconut palms, and more than 75 yr of open-cast phosphate mining in the case of Nauru have led to serious vegetation degradation, disturbance, and displacement. The floras of Nauru and the Gilbert Islands consist of
Ten composite soil samples (0-15 cm depth) were collected from abandoned phosphate-mined sites on Nauru Island (Central Pacific) and analyzed for % organic C and % N. The samples represent a temporal sequence (chronosequence) of soil development spanning < 55 yr. The increase of% C and % N was fairly rapid.
The environment of Nauru, a raised atoll located in the central Pacific Ocean (0° 32′ S, 166° 56′ W), was
devastated by mining of phosphate “rock” during the twentieth century. Some 100 million tonnes of
phosphate material has been removed, leaving more than 80% of the island as a dolomite
pinnacle–dominated karrenfeld. Based on fieldwork examining sites unmined at that time, laboratory
studies on undisturbed profiles, aerial photographs, and old mining maps, a picture of what the soil
