SENTINEL-2 is a wide-swath, high-resolution, multi-spectral imaging mission, supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
The SENTINEL-2 Multispectral Instrument (MSI) samples 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution.
Environmental conditions and anthropogenic impacts are key influences on ecological processes and associated ecosystem services. Effective management of Tonga’s marine ecosystems therefore depends on accurate and up-to-date knowledge of environmental and anthropogenic variables. Although many types of environmental and anthropogenic data are now available in global layers, they are often inaccessible to end users, particularly in developing countries with limited accessibility and analytical training.
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (originally known as EOS AM-1) and Aqua (originally known as EOS PM-1) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications).
The Database of Island Invasive Species Eradications (DIISE) attempts to compile all historical and current invasive vertebrate eradication projects on islands. The vast majority of the dataset is focused on invasive mammals. Data gathered from each project includes island location and characteristics, details about the eradication including focal species, methods and outcome, plus links and or contact details for learning more about the project.
The UN Biodiversity Lab is an online platform that allows policymakers and other partners to access global data layers, upload and manipulate their own datasets, and query multiple datasets to provide key information on the Aichi Biodiversity Targets and nature-based Sustainable Development Goals.
A list of international and regional multilateral environmental agreements in which each of the Pacific Island country is a party/signatory of. This is useful for SPREP activities and planning
The overall objectives of the mangroves survey is conservation of biodiversity by means of sustainable used of mangroves ecosystem and natural resources. In supporting the objectives two primary objectives need to be address;
1. Collecting baseline data on mangrove and associated ecosystem at Koloa and Holeva and other sites as time permits
2. To develop mangroves species zoning using QGIS application and software along with GPS and using the Pacific Mangrove Monitoring Manual as a field guide and methodology.
The Pacific Network for Environmental Assessment (PNEA) Portal is an initiative of the Secretariat of the Pacific Regional Environment Programme (SPREP) to support government officials from Pacific Island countries and territories who work with environmental impact assessment (EIA), strategic environmental assessment (SEA) as well as Environmental and Social Safeguards (ESS).
The portal complements SPREP’s current capacity building program for EIA and SEA - including the recently launched Regional EIA Guidelines, the Coastal Tourism EIA guidelines, and SEA guidelines.
The Tonga State of the Environment 2018 report has been developed to answer three key questions related
to the environment of Tonga, and is based on seven thematic areas:
• What is the current condition of the Tongan environment?
• What are the risks the Tongan environment faces and what measures have been put forward to minimise them? This could provide lessons for Tonga.
• Where is the environment of Tonga headed based on the assessed thematic areas?
The World Database on Protected Areas (WDPA) is the most comprehensive global database of marine and terrestrial protected areas, updated on a monthly basis, and is one of the key global biodiversity data sets being widely used by scientists, businesses, governments, International secretariats and others to inform planning, policy decisions and management.
Tonga’s State of Environment Report 2018 is complete and currently awaiting official approval and launch. The report is based on 7 thematic areas and it was developed to answer 3 key questions related to the environment;
1. What is the current condition of the Tongan environment?
2. What are the risks the Tongan environment faces and what measures have been put forward to minimise them
3. Where is the environment of Tonga headed based on the assessed thematic areas?
Tonga's Environment Data Portal was employed as the tool for SOE data storage and sharing
This dataset gives an overview of the Hunga-Tonga Hunga-Ha'apai volcanic eruption that occurred on 15 Jan, 2022 and led to an induced tsunami event. From updates, to spatial maps and damage preliminary impact assessments detected from Pleiades images. You can easily access and find them all on this dashboard.
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.
In the 30th SPREP meeting held in September this year, the meeting supported the scaling up of environment data management in the Pacific and directed the Secretariat to initiate a process for developing a full-sized project proposal to support the scaling up environmental data management work in the region.
Later in October, the Inform Project participating countries collectively agree on the need to scale up and extend the Inform Project services beyond 2022.
