Shaping the Huara Intrusive Complex in the Hyperarid Atacama Desert—Erosional Near‐Stasis Contrasting High Topographic Gradients

open access: yesJournal of Geophysical Research: Earth Surface, Volume 128, Issue 3, March 2023., 2023
Abstract The Atacama Desert is one of the driest and oldest deserts on Earth, with extremely low precipitation rates (<2 mm/yr). Mostly abiotic hyperarid environmental conditions prevail, and surface processes act at extremely low rates over the long‐term.

RADARGRAMMETRIC DIGITAL SURFACE MODELS GENERATION FROM TERRASAR-X IMAGERY: CASE STUDIES, PROBLEMS AND POTENTIALITIES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
The interest for the radargrammetric approach to Digital Surface Models (DSMs) generation has been growing in last years thanks to the availability of very high resolution imagery acquired by new SAR (Synthetic Aperture Radar) sensors, as COSMO-SkyMed,

Climate and socioeconomic drivers of biomass burning and carbon emissions from fires in tropical dry forests: A Pantropical analysis

open access: yesGlobal Change Biology, Volume 29, Issue 4, Page 1062-1079, February 2023., 2023
About 20% of the Pantropical tropical dry forest biomass is affected by fires of which small fires explain most of it. The spatial distribution of small fires is related to socioeconomic and biophysical drivers, while climatic conditions drive large and intense fires.

3D GNSS Velocity Field Sheds Light on the Deformation Mechanisms in Europe: Effects of the Vertical Crustal Motion on the Distribution of Seismicity

open access: yesJournal of Geophysical Research: Solid Earth, Volume 127, Issue 6, June 2022., 2022
Abstract Crustal deformation and seismicity in Europe are still poorly understood. Seismic activity is classically ascribed to crustal strain rates generated by edge‐driven tectonic forces. However, crustal deformation is not only due to tectonic loading, but can also be related to isostatic and mantellic processes that induce additional stress and ...

Strain Accommodation by Intrusion and Faulting in a Rift Linkage Zone: Evidences From High‐Resolution Topography Data of the Afrera Plain (Afar, East Africa)

open access: yesTectonics, Volume 41, Issue 6, June 2022., 2022
Abstract At mature magma‐rich continental rifts, extension focuses along discrete axial segments where magmatism and diking are important in accommodating plate divergence. However, the role of magma in influencing the deformation at rift–rift offsets is still unclear as direct observations are rare.

Multiple anthropogenic pressures challenge the effectiveness of protected areas in western Tanzania

open access: yesConservation Science and Practice, Volume 4, Issue 6, June 2022., 2022
We investigated temporal changes in land‐use and population densities of six large mammal target species across areas with different conservation category. During six survey periods between 1991 and 2018, we analysed data from remote sensing and aerial wildlife surveys to derive spatio‐temporal patterns of cropland cover in relation to protection ...

Coastal wetland responses to a century of climate change in northern Sahara, Morocco

open access: yesLimnology and Oceanography, Volume 67, Issue 2, Page 285-299, February 2022., 2022
Abstract Coastal wetlands are highly sensitive to changes occurring at the coastline. It is critically important to determine region‐specific projections for these areas due to their specificities and vulnerabilities to climate change. This work aimed to value the impacts of recent climate changes at West Africa Sahara coastland, southern Morocco, at ...

Global application of an unoccupied aerial vehicle photogrammetry protocol for predicting aboveground biomass in non‐forest ecosystems

open access: yesRemote Sensing in Ecology and Conservation, Volume 8, Issue 1, Page 57-71, February 2022., 2022
Working at sites across the globe, we used a standardized protocol to collect and analyse drone data in order to measure the size of many different plants in non‐forest ecosystems. These measurements of canopy height allowed the prediction of aboveground biomass and carbon storage of different plants accurately across the landscape.

Identification of Geothermal Reservoirs in South Cameroon from a Combined Landsat 8 and AMT Data

open access: yesInternational Journal of Geophysics, Volume 2022, Issue 1, 2022., 2022
This geothermal source prospecting work is carried out in order to respond to the energy deficit affecting the populations of South Cameroon in particular. The study combines audio‐magnetotelluric (AMT) and Landsat 8 data for the geolocation of reservoirs, as well as the geological and tectonic information.

The power of Virtual Globes for valorising cultural heritage and enabling sustainable tourism: NASA World Wind applications [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Inspired by the visionary idea of Digital Earth, as well as from the tremendous improvements in geo-technologies, use of virtual globes has been changing the way people approach to geographic information on the Web.
