Bravo Senegal 🇸🇳! Senegal is planting 80 million trees to fight desertification, protect farmland, and fight the climatecrisis. Great green, naturebased solution!

Last week researchers from the GIUB #remotesensing group and @ZFLbonn presented their reserach on #landdegradation #croplands #wetlands #locusts & #biodiversity at the @ESA_EO Living Planet Symposium in Bonn.

Abdel-Hamid et al. find that integration of ALOS/PALSAR L-band, #RapidEye optical imagery, #OBIA, and random forest #machinelearning is best for mapping #mangrove extent along the #RedSea coastline in Egypt with an overall accuracy of ~92%. #rswetlands mdpi.com/2071-1050/10/3…

#ImageOfTheDay The oases in the deserts of #Egypt 🇪🇬 are a unique mix of archaeology⛏️📖 and #biodiversity🌴🌾 ⬇️@CopernicusEU #Sentinel2 🇪🇺🛰️view of the Dakhla Oasis, an oasis reach in agricultural activities but with zero rainfall where all the water supply is "fossil water"

Glaciers are melting! #Drone surveying of Peyto Glacier with #lidar #thermal and #multispectral sensors is our contribution to understanding how fast it is melting and what that means for the headwaters. @CentreForHydro @GWFutures @usask_water

Happy Africa Day.

It’s #WorldBeeDay! #DYK? Pollinators help minimize the impact of climate change on food security. Protecting them can secure our future of food! #GlobalGoals

Our new #openaccess article is out on assessing the impact of #drought stress on #grasslands in Eastern Cape, South Africa, using multi-temporal #SAR data of #Sentinel1. doi.org/10.1080/227972… @VAMGraw @ZFLbonn @GIUB_Research @UniBonn

What is better than an image of a biodiversity hotspot to launch the @UNBiodiversity #BiodiversityWeek celebrations? Here is a #Sentinel2 🇪🇺 🛰 image of the São Francisco River estuary, #Brazil 🇧🇷, located in the Atlantic Forest #Bioregion

@tyhwoh5 you are welcome.

@aymhamid i cant wait to meet you. To discuss and learn earth observations

A clear view of the #AnakKrakatau volcano in #Indonesia, captured today by @CopernicusEU #Sentinel2. Thanks to the satellite's short wave infrared channels we can easily spot the ongoing activity in the crater, visible in bright red.
