Oases of Western Desert

The Western Desert covers about 700,000 square kilometres and accounts for about two-thirds of Egypt's land area. It spans from the Mediterranean Sea south to the Sudanese border and from the Nile River Valley west to the Libyan border. There are seven important depressions within this area and all of these are considered oases (Siwa, El Faiyum, Bahariya, Farafra, Dakhla, Kharga) except the largest, Qattara. There are also two large agricultural schemes in the south, Sharq Oweinat near the Sudanese border and Tushka near Lake Nasser.

The Western Desert is one of the driest areas of the Sahara. The last significant rain fell six years ago which caused natural vegetation to remain green for two years. Desert Locust hopper bands and adults swarms formed and were controlled three months after the rains in the spring of 1995. Since then, there has been an increase in the number of reports of grasshoppers and locusts from newly established agricultural schemes at Sharq Oweinat and Tushka.
