Introduction

Egypt officially the Arab Republic of Egypt, is a country mainly in North Africa, with the Sinai Peninsula forming a land bridge in Southwest Asia. Egypt is thus a transcontinental country, and a major power in Africa, the Mediterranean Basin, the Middle East and the Muslim world. Covering an area of about 1,010,000 square kilometers (390,000 sq mi), Egypt is bordered by the Mediterranean Sea to the north, the Gaza Strip and Israel to the northeast, the Red Sea to the east, Sudan to the south and Libya to the west. The Nile at Cairo

Egypt is one of the most populous countries in Africa and the Middle East. The great majority of its estimated 80 million people  live near the banks of the Nile River, in an area of about 40,000 square kilometers (15,000 sq mi), where the only arable land is found. The large areas of the Sahara Desert are sparsely inhabited. About half of Egypt's residents live in urban areas, with most spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.Monuments in Egypt such as the Giza pyramid complex and its Great Sphinx were constructed by its ancient civilization. Its ancient ruins, such as those of Memphis, Thebes, and Karnak and the Valley of the Kings outside Luxor, are a significant focus of archaeological study. The tourism industry and the Red Sea Riviera employ about 12% of Egypt's workforce. The economy of Egypt is one of the most diversified in the Middle East, with sectors such as tourism, agriculture, industry and service at almost equal production levels. In early 2011, Egypt underwent a revolution, which resulted in the ousting of President Hosni Mubarak after nearly 30 years in power.

Geography & Climate

At 1,001,450 square kilometers (386,660 sq mi),Egypt is the world's 30th-largest country. In land area, it is about the same size as all Central America,twice the size of Spain, four times the size of the United Kingdom,[48] and the combined size of the US states of Texas and California.[49] It lies between latitudes 22° and 32°N, and longitudes 24° and 36°E.

Nevertheless, due to the aridity of Egypt's climate, population centres are concentrated along the narrow Nile Valley and Delta, meaning that about 99% of the population uses only about 5.5% of the total land area.[50] Egypt is bordered by Libya to the west, Sudan to the south, and by the Gaza Strip and Israel to the east. Egypt's important role in geopolitics stems from its strategic position: a transcontinental nation, it possesses a land bridge (the Isthmus of Suez) between Africa and Asia, traversed by a navigable waterway (the Suez Canal) that connects the Mediterranean Sea with the Indian Ocean by way of the Red Sea.Apart from the Nile Valley, the majority of Egypt's landscape is desert. Winds create prolific sand dunes that peak at more than 100 feet (30 m) high. Egypt includes parts of the Sahara Desert and of the Libyan Desert. These deserts that protected the Kingdom of the Pharaohs from western threats were referred to as the "red land" in ancient Egypt.

The Nile at Cairo

Towns and cities include Alexandria, one of the greatest ancient cities, Aswan, Asyut, Cairo, the modern Egyptian capital, El-Mahalla El-Kubra,Giza, the site of the Pyramid of Khufu, Hurghada, Luxor, Kom Ombo, Port Safaga, Port Said, Sharm el Sheikh, Suez, where the Suez Canal is located, Zagazig, and Al-Minya. Oases include Bahariya, el Dakhla, Farafra, elKharga and Siwa. Protectorates include Ras Mohamed National Park, Zaranik Protectorate and Siwa.

Most of Egypt's rain falls in the winter months. South of Cairo, rainfall averages only around 2 to 5 mm (0.1 to 0.2 in) per year and at intervals of many years. On a very thin strip of the northern coast the rainfall can be as high as 410 mm (16.1 in), mostly between October and March. Snow falls on Sinai's mountains and some of the north coastal cities such as Damietta, Baltim, Sidi Barrany, etc. and rarely in Alexandria. Frost is also known in mid-Sinai and mid-Egypt.

Temperatures average between 80 °F (27 °C) and 90 °F (32 °C) in summer, and up to 109 °F (43 °C) on the Red Sea coast. Winter temperatures average between 55 °F (13 °C) and 70 °F (21 °C). A steady wind from the northwest helps lower temperatures near the Mediterranean coast. TheKhamaseen is a wind that blows from the south in spring, bringing sand and dust, and sometimes raises the temperature in the desert to more than 100 °F (38 °C).Prior to the construction of the Aswan Dam, the Nile flooded annually (colloquially The Gift of the Nile) replenishing Egypt's soil. This gave the country consistent harvest throughout the years.The potential rise in sea levels due to global warming could threaten Egypt's densely populated coastal strip and have grave consequences for the country's economy, agriculture and industry. Combined with growing demographic pressures, a significant rise in sea levels could turn millions of Egyptians into environmental refugees by the end of the century, according to some climate experts.

Environment - current issues

 agricultural land being lost to urbanization and windblown sands; increasing soil salination below Aswan High Dam; desertification; oil pollution threatening coral reefs, beaches, and marine habitats; other water pollution from agricultural pesticides, raw sewage, and industrial effluents; limited natural freshwater resources away from the Nile, which is the only perennial water source; rapid growth in population overstraining the Nile and natural resources.
