Eichhornia crassipes expansion detection using geospatial techniques: Lake Dambal, Oromia, Ethiopia
Eichhornia crassipes growth is threatening fresh water bodies such as Lake Dambal. The study's goal is to map Eichhornia crassipes expansion and detect changes from 2017 to 2021. The instrument used to collect field point data was the Geographical Positioning System. The USGS and Copernicus Hub...
