This study focuses on assessing crop productivity and water use efficiency in the northern region of Gaza through remote sensing and field measurements. It aims to accurately map and identify crop types in the study areas using remote sensing data, including satellite imagery and in situ measurements. The objective of this study is to conduct crop type mapping and water consumption mapping based on evapotranspiration (ET). Calculating evapotranspiration alone does not give definitive indicators, because it does not calculate leaching requirements of crops, nor does it calculate the efficiency of irrigation systems using remote sensing techniques. The study covers the period from 2021 to 2023 and focuses on the summer and winter seasons in East Gaza city (Al-Shujaia), Beit Hanoun and East Jabalia North Gaza.
