The objectives of this study were as follows:
1. Resurvey and delineation of the sand resource of eight beaches on Tongatapu
2. Evaluation of the extent of recent coastal changes on Tongatapu including changes effected by cyclones and other natural events, beach sand extraction, and interaction between the two.
3. Investigation of the rate of sand production and implications for the sustainability of beach mining.
This report is mainly focused on a research to find out the importance of Integrated Coastal Management to the coastline of Tongatapu. It aims to notify the changes of coastal areas and to what extent; identify these changes cause issues on the sustainability of the coastline in terms of social, economic and environmentally; and to evaluate the procedures of coastal monitoring and resource management in Tonga.
Report on survey work to provide baseline information on the status of reef
fisheries, and to help fill the massive information gap that hinders the effective management
of reef fisheries. Surveys took place 2001, 2002 and 2008.
The Tonga NPOA (sharks) is a policy guideline that ensures conservation and management of oceanic sharks in the Kingdom’s fisheries waters. It also promotes long-term sustainability and optimum use of sharks in Tonga’s Tuna longline fishery in accordance to national development policy frameworks, and special needs and requirements to develop and commercialise its fisheries. In the medium-long term, the Plan serves to minimize any adverse environmental effects of fishing on oceanic shark species.

Marine pollution in the Pacific. Regional data
This EIA report had been prepared for the major development and upgrade of the inter-island domestic wharf located in Tongatapu Island.
MACBIO is a project that supports sustainable economies and livelihoods of Pacific Island Countries by strengthening institutional and individual capacity, to manage and conserve biodiversity in marine and coastal ecosystems. The project was commissioned by BMUB to GIZ as part of IKI, jointly implemented by SPREP, IUCN and GIZ from 2013 to 2018.
This dataset holds all MACBIO-related resources pertaining to Tonga as one of the participating countries.
The development of the haul out and storage facility, especially catering to the requirements of visiting yachts and locally based commercial boats in the Vaipua area on the outskirts of Neiafu, Vava’u.
This EIA is therefore primarily concerned with development activities including the construction of a slipway (92m by 6m) and land clearance of surrounding vegetation as well as specific operational activities with potential negative environmental impacts.
The Tonga Fisheries Sector Plan (TFSP) is a framework for increasing the sustainable shared benefits for the
Kingdom from optimal use of its living marine resources.
Between September 10, 2013 – October 3, 2013 the Khaled bin Sultan Living Oceans Foundation conducted a
research mission to Tonga, focusing on coral reefs surrounding the islands in the Ha'apai group (Sep 11-21),
Vava'u (Sep 22-28) and Niuaatoputapu (Sep 29-Oct 1). The mission included coral reef assessments, coral reef
research, habitat mapping, and educational activities. The objectives of the mission were to:
The Hunga Tonga-Hunga Ha'apai massive undersea volcanic eruption occurred on the 15th of January 2022 and led to an induced tsunami event. The eruption triggered a tsunami warning for several South Pacific island nations with rising water levels were reported on the coastline of Peru and the Pacific Coast in the United States and caused devastating impact across Tonga. In addition, volcanic ash residue was also visible on land surfaces including building structures and surrounding vegetation.
This dataset contains preliminary impact assessments of the Hunga-Tonga-Hunga-Ha'apai volcanic eruption and induced tsunami in January 2022.
The eruptions sent a plume of ash, gas and steam 20 kilometers (12.4 miles) into the air. Satellite imagery showed a massive ash cloud and shockwaves spreading from the eruption. Ash was falling from the sky in the Tonga capital, Nuku'alofa, Saturday evening and phone connections were down. The eruption was likely the biggest recorded anywhere on the planet in more than 30 years, according to experts.
This publication intends to assist project designers, regulators and decision makers to anticipate and address all relevant public health, socio‐economic and environmental concerns that may arise when under‐ taking a desalination project, for obtaining maximum beneficial use of the desalinated water in terms of quality, safety and environmental protection.

There is a high level of uncertainty with the specific estimation of pollutant loads. A large body of work has
been completed that provided qualitative and quantitative data; however, the noting of data gaps and inherent uncertainties of the methods used have qualified much of the quantitative data. Much of the data are based on rapid assessment methods that utilise generic loading rates, assumed waste flow composition, typical production methods, local production rates. Unfortunately, production rate data are inconsistently available and are difficult to verify.
Spearfishing is growing in importance in the Pacific Islands. While its management has featured as a topic in some regional-level meetings, detailed information on spearfishing is surprisingly scarce. In early 1994, the Secretariat of the Pacific Community (SPC) proposed to consolidate information on
This report presents the results of a twelve day survey expedition (5 to 16 December, 2004) and represents the first ever systematic effort to document the marine biodiversity of the Great Sea Reef (GSR), locally known as Cakaulevu, to the north of Vanua Levu in the Fiji Archipelago. 23 sites were surveyed over 6 major habitat types: outer barrier reefs, back barrier reefs, channels, mangrove island fringing reefs, rocky island fringing reef and submerged patch reefs.

The study of marine sediments provides useful information in marine, environmental and geochemical research about pollution of the marine environment (Calace et al. 2005). Urban developments and industrial activities contribute to the introduction of significant amounts of contaminants (among them trace metals) into the marine environment and affect directly the coastal systems where they are often deposited (Angelidis 1995; Dassenakis et al. 2003).
The World's oceans play a crucial role for life on the planet.
Healthy seas and the services they provide are key to the future
development of mankind. Our seas are highly dynamic, structured and complex systems. The seafloor consists of vast shelves
and plains with huge mountains, canyons and trenches which
dwarf similar structures on land. Ocean currents transport water
masses many times larger than all rivers on Earth combined.
