Reefs at Risk Revisited is a high-resolution update of the original global analysis, Reefs at Risk: A Map-Based Indicator of Threats to the World’s Coral Reefs. Reefs at Risk Revisited uses a global map of coral reefs at 500-m resolution, which is 64 times more detailed than the 4-km resolution map used in the 1998 analysis, and benefits from improvements in many global data sets used to evaluate threats to reefs (most threat data are at 1 km resolution, which is 16 times more detailed than those used in the 1998 analysis).

The Western and Central Fisheries Commission (WCPFC) have compiled a public domain version of aggregated catch and effort data using operational, aggregate and annual catch estimates data provided by Commission Members (CCMs) and Cooperating Non-members (CNMs). The data provided herein have been prepared for dissemination in accordance with the current “Rules and Procedures for the Protection, Access to, and Dissemination of Data Compiled by the Commission” or (“RAP”).
The Sea Around Us is a research initiative at The University of British Columbia (located at the Institute for the Oceans and Fisheries, formerly Fisheries Centre) that assesses the impact of fisheries on the marine ecosystems of the world, and offers mitigating solutions to a range of stakeholders.
The Sea Around Us was initiated in collaboration with The Pew Charitable Trusts in 1999, and in 2014, the Sea Around Us also began a collaboration with The Paul G. Allen Family Foundation to provide African and Asian countries with more accurate and comprehensive fisheries data.
AquaMaps are computer-generated predictions of natural occurrence of marine species, based on the environmental tolerance of a given species with respect to depth, salinity, temperature, primary productivity, and its association with sea ice or coastal areas. These 'environmental envelopes' are matched against an authority file which contains respective information for the Oceans of the World. Independent knowledge such as distribution by FAO areas or bounding boxes are used to avoid mapping species in areas that contain suitable habitat, but are not occupied by the species.
Marine Bioregions of the Southwest Pacific - Marine and Coastal Biodiversity Management in Pacific Island Countries (MACBIO)
Bioregions, of course, are just one of the important data layers in indentifying an ecologically representative system of marine protected areas. To be truly ecologically representative and comprehensive, one must also consider all available information about habitats, species and ecological processes. In addition, socio-economic and cultural considerations are vital in the spatial planning process. This report is focussed upon one important, but only one, input to marine spatial planning: the development of marine bioregions.
Dataset includes various regional-scale spatial data layers in geojson format.

This report was presented by Tuvalu during the 3rd international conference on small island developing states. It reported the status of sustainable development (SD), outlining the good progress that has been achieved in the pursuit of sustainable development as the country follows the strategies recommended by the international community for small island developing states (SIDS).

This academic paper investigates the vulnerability of households to climatic disasters in the low-lying atoll nation of Tuvalu. Using the most recent household surveys available, the authors constructed poverty and hardship profiles for households on the different islands of Tuvalu, and combine these with geographic and topographic information to assess the exposure differentials among different groups using spatial econometric models.
The map is a fundamental tool for local resident and island management. It was constructed by latest and high-resolution satellite images and the measured results of field investigation by Foram Sand Project, J-PACE and SOPAC.
Tuvalu's shallow marine environments are dominantly fringing and patch reefs. Five of the islands are true coral atolls, with a continuous eroded reef platform surrounding a central lagoon, three islands are comprised of a single islet made up of sand and coral materials (McLean & Hosking, 1991). This article documents the status of corals reefs of Tuvalu, including threats to coral reef biodiversity.
The Funafuti Conservation Area project has been relatively successful, therefore this report documents the lessons learned as well as providing a useful model for similar marine conservation projects at other sites within the country and around the region.
The Global Nutrition Reports capture the status of nutrition at the country, regional and global level.
This country profile for Tuvalu aggregate the very latest data on child, adolescent and adult anthropometry and nutritional status, as well as intervention coverage, food supply, nutrition spending and demography. Interesting environmental data relating to water and sanitation are also briefly presented.
This project report has two components
1) a field survey of the fish biodiversity of Tuvalu’s reefs and lagoons, as well as documenting the species commonly caught by local fishermen and
2) a field survey of selected macro-invertebrate and fish densities in Tuvalu’s lagoons, to assess the stocks of valuable species on each atoll and test the effectiveness of the Conservation Areas (CAs).
This study addresses rainfall trends, the frequency of droughts, La Niña influences and the relationship between rainfall and Sea Surface Temperature (SST) in Tuvalu. The findings revealed that;
* de-trended rainfall time series show declining trends in all four rainfall stations over the period 1953-2012;
* the frequency of drought ranges from three to fourteen years with a mean of nine years
* the occurrence of drought appears to follow the La Niña years
* boplots provide an effective option for defining drought
This article presents an analysis of shoreline change in all 101 islands in the Pacific atoll nation of Tuvalu. Using remotely sensed data, change is analysed over the past four decades, a period when local sea level has risen at twice the global average (~3.90 ± 0.4 mm.yr−1). Results highlight a net increase in land area in Tuvalu of 73.5 ha (2.9%), despite sea-level rise, and land area increase in eight of nine atolls.
This report describes the high-resolution bathymetric mapping survey carried out in 2004. The survey achieved good coverage of the seafloor from approximately 10 m depth in the nearshore reef slope area, to an average offshore depth of some 2000 m, at an average slope angle of 2. The objective was to investigate the seabed and provide information about water depths around the islands using a multibeam echosounder (MBES).
