Small oceanic islands, such as São Miguel Island in the Azores (Portugal), face heightened susceptibility to the adverse impacts of climate change, biological invasions, and land cover changes, posing threats to biodiversity and ecosystem functions and services. Over the years, persistent conservation endeavors, notably those supported by the EU LI...

Small oceanic islands, like São Miguel Island (Azores), show high vulnerability to climate change impacts, biological invasions, and land-use/land-cover changes that threaten their biodiversity and affect their ecosystem functions and services. Organized and long-term nature conservation actions and projects such as those funded by the EU LIFE Prog...

As the global community grapples with the complex challenges of climate change, the integration of nature-based solutions (NBS) has emerged as a critical strategy. This work introduces a Web Geographic Information System (WebGIS) designed to showcase and communicate the results of initiatives focused on NBS within the scope of the Marine Coastal Ec...

In the current climate change context, detecting and monitoring relevant land use/land cover (LULC) changes in insular and coastal areas is critical as soon as they occur. This research consists of a systematic literature review of 167 open-access articles from January 2010 to June 2022, based on several parameters, namely year of publication, jour...

Insular ecosystems are natural laboratories in which evolution processes may be isolated and examined before being connected and expanded to the more complicated patterns displayed by more extensive systems. Similarly, islands can provide insights into effective land/costal management techniques. In the current climate change context, and with most...

Current-day volcanic activity in the Azores archipelago is characterized by seismic events and secondary manifestations of volcanism. Remote sensing techniques have been widely employed to monitor deformation in volcanic systems, map lava flows, or detect high-temperature gas emissions. However, using satellite imagery, it is still challenging to i...

The Ribeira Grande geothermal field is located on the northern flank of Fogo Volcano (S. Miguel Island, Azores) and it is characterised by the presence of several active hydrothermal manifestations. An analysis of the RG5 geothermal well has been carried out by the recognition of neoformation minerals with depth and the estimation of equilibrium te...

Abstract: The last eruption in the Fogo Volcano, which began in November 2014, was the first eruptive event captured by the Sentinel-1 (S1) mission. The present work sought to complement previous research and explore the potential of utilizing data from the Synthetic Aperture Radar (SAR) S1 mission to better monitor active volcanic areas. S1 Ground...
