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).
This paper investigates the water quality of the densely populated lagoonal coasts in Fongafale Islet, and the occurrence of water pollution. A comparison was then made with less populated natural coast in the islet. The primary pollution sources and pollution mechanism were identified. Through this investigation, the need for effective water quality control measures for coastal conservation is demonstrated.
Waste Policy and Action Plan
uPOPs Action Plan
Tuvalu’s environment is under pressure: sea-water rise contaminating the soil with salt, direct impact on waste and sewage systems from rising human density contributing to further damage. The 1987 UN Brundlandt report has definitely shown the existing link between environment/ecology and development /economy. Tomorrow’s economy stems from today’s environment.
Under the International Waters Project (IWP) in Tuvalu, a pilot project was established to address
“waste” with the aim of reducing the contamination of groundwater and coastal water by human
and animal waste.
Community-based activities included “low-tech” solutions to addressing environmental
degradation while national level activities involved activities with a more strategic institutional
focus. A Communications and Sanitation Training Programme was designed to investigate the
This report presents the outcome of the 2nd Review of Tuvalu’s Integrated Waste Policy Action Plan 2017-2026, providing the updates on the implementation status of the Policy during the period January 2018 – March 2019. This Review follows the 1st Review conducted in 2018 for the period June 2016 to December 2017.
Waste audit and interview data collected by APWC in October 2019.

This dataset hosts the published NEMs of Tuvalu;
Biodiversity is part and parcel of Tuvalu's development framework. This NBSAP is the first formal consolidated attempt to address biodiversity issues and constraints in Tuvalu in a comprehensive manner.
Tuvalu is among the most vulnerable to climate change impacts. This dataset hosts the national communications to the United Nations Framework Convention on Climate Change.

Although Tuvalu has no history of manufacturing persistent organic pollutants (POPs), this data-set consists of;
1. the first report (2008) that represents the first stepping stone for the country to outline strategies in order to meet its obligations under the Stockholm Convention, also given the chemical nature, including long range environmental transport of POPs that is a global concern.
2. The Tuvalu National Action Plan to reduce releases of unintentional persistent organic pollutants (u-POPs) 2018 - 2022
