Project Overview

Ensuring food security and sustainable growth are among the top priorities of the Egyptian government. Major programs have been undertaken in the last decades to relieve population pressure along the narrow Nile Valley, increase Egypt’s arable land, and generate new employment opportunities, especially for young people. One significant step toward accomplishing these goals is the selection of suitable sites for urban and agricultural development. Remote sensing technology has made timely and spatially explicit information gathering possible with a wide variety of sensors operating in the optical and microwave region of the solar spectrum. Despite the increasing level of sophistication of these sensors, field information is a required component of any remote sensing study to ensure proper calibration and validation of data.

 

This project worked with an existing U.S.-Egyptian project involving field surveys (including ground penetrating radar and soil and water sampling for lab analysis) in the El-Gallaba Plain, bounded in the east by the River Nile and in the west by the scarp face of the Sin El-Kaddab Plateau. Although soil maps exist for this region from the time when the Aswan High Dam was constructed in the 1960s, these maps do not cover the area in sufficient detail. The project addressed this problem by producing a detailed surface sediment and soil map that will provide a basis for assessing and monitoring soil types and conditions and their suitability for urban and agricultural development. The researchers conducted a spectral soil mapping campaign in conjunction with other ongoing field surveys and created a library of representative surface materials to be used in conjunction with present and future satellite sensors to spatially map the distribution of soils and surface sediments. The library will be made available to the public and used for a training workshop in spectral mapping techniques.
