The Global Mangrove Watch (GMW) is a collaboration between Aberystwyth University (U.K.), solo Earth Observation (soloEO; Japan), Wetlands International the World Conservation Monitoring Centre (UNEP-WCMC) and the Japan Aerospace Exploration Agency (JAXA).
Conservation International, GRID-Arendal and Geoscience Australia recently collaborated to produce a map of the global distribution of seafloor geomorphic features. The global seafloor geomorphic features map represents an important contribution towards the understanding of the distribution of blue habitats. Certain geomorphic feature are known to be good surrogates for biodiversity. For example, seamounts support a different suite of species to abyssal plains.

The increased demand for high quality products in export markets, coupled with Pacific Island Countries (PICs) national desire to protect the environment, biodiversity and family farming structures, lead to assume that organic agriculture could offer good prospects for PICs development. Besides market opportunities, organic agriculture could increase PICs food self-reliance and thus, contribute to reducing the alarming trend of dependency on food imports, as well as improving nutrition.
Damage assessment as detected from a Pleiades image acquired on 18 January 2022 in Nomuka Island (Mu'omu'a district, Tonga).
260 structures identified, 52 structures were identified as damaged and/or destroyed, 13 as potentially flooded and almost all structures were covered with ash. This is a preliminary analysis and has not yet been validated in the field
