An underwater volcanic eruption off the Vava’u island group in Tonga on 7 August 2019 resulted in the creation of floating pumice on the ocean’s surface extending over an area of 150 km2. The pumice’s far-reaching effects from its origin in the Tonga region to Fiji and the methods of automatic detection using satellite imagery are described, making...

La quantité des images satellitaires et des données qui en sont issues sur la biodiversité est telle qu’elle ouvre de nouvelles voies de recherche, pour lesquelles les spécialistes de la biodiversité, de la télédétection et inédit de connaissances constitue un enjeu majeur pour les pays du Sud, où la biodiversité est moins bien répertoriée
The perpetuity and improvement of REDD+ projects for curbing deforestation require rigorous impact evaluations of the effectiveness of existing on-the-ground interventions. Today, a number of global and regional remote sensing (RS) products are publicly available for detecting changes in forest cover worldwide. In this study, we assess the suitabil...
