Crop mapping using remote sensing in Malawi site, Egypt

Abstract

Crop mapping is key for estimating crop water productivity and the crop production per water consumed. It enables to characterize at a given time the spatial distribution of the main crop. The use of remote sensing applications combined with calibration with field data enable to create time relevant inventories and produce maps for the various cropping seasons to inform strategic planning, production monitoring for decision-making. The availability of accurate crop map is precious information for estimating crop yields, land and water productivity, estimating water consumption needed for water balance, calculation of actual evapotranspiration and it is a key input in water accounting calculation. It also indicates opportunities and risks for food security when looking at staples crops such as cereals.
