Crop Water Requirements Estimation in Gaza Strip, ArcMap Model Builder
Authors: Ali Salha
Gaza Strip is in critical situation where demand exceeds water supply due to resources exploitation. There are over 4,000 agricultural water wells which 70% are illegal where accurate consumption figures do not exist. Thus, agricultural water consumption is estimated by using ArcMap GIS- Model Builder approach (utilizing land use, rainfall, other meteorological data), where 49 computation processes were built in. Maps showing spatial distribution of monthly crop water requirement are produced.
