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.
