    Libya is characterized by water scarcity. The land cover map is required to support crop and water productivity in Libya. Sampling design needs to be carried out to identify suitable locations for field surveys to collect data for land cover mapping. Stratification based on changes in vegetation and water productivity is carried out to identify the optimum number of sampling locations in Fezzan, Libya at the parcel level

    The land cover map (2022) of Fezzan is prepared to support decision making to improve crop and water productivity. The training data of various land cover classes collected using high resolution imageries and trained using supervised classification in SEPAL with Sentinel-2 satellite imageries. The land cover is obtained at 10 m spatial resolution. The results should be further enhanced with ground validation data.
