| Outline of Final Research Achievements |
Desertification in Egypt has rapidly advanced since the Early Dynastic Period. This study aimed to elucidate the process of environmental change for deepening our knowledge of how people conducted their life within the arid environment. Magnetic spherical fractions extracted as proxies from sand deposits suggested the environmental change featured by two humid-dry cycles within 4,200～6,700 calBP. A fault was found by Electro-Magnetic sounding in Kharga Oasis. Two drilling profiles were obtained at the vicinity of springs along the fault zone and in the field relics in the lowland. The results of the chemical and mineral analyses for the field-relic profile suggested the occurrence of environmental change including effects of irrigated water and cultivation.
Landsat chronological data and DEM imageries of SRTM were utilized to understand the recent 30 years’land use change in Kharga oasis, having its own water source since ancient days, and the drastic change expected in future.
