The Negev (also Negeb; Hebrew: נֶּגֶב‎‎, Tiberian vocalization: Néḡeḇ) is a desert and semidesert region of southern Israel. The Arabs, including the native Bedouin population of the region refer to the desert as al-Naqab (Arabic: النقب‎). The origin of the word Neghebh (or in Modern Hebrew Negev) is from the Hebrew root denoting 'dry'. In the Bible the word Neghebh is also used for the direction 'south'.

Geography

The Negev covers more than half of Israel, over some 13,000 km² (4,700 sq mi) or at least 55% of the country's land area. It forms an inverted triangle shape whose western side is contiguous with the desert of the Sinai Peninsula, and whose eastern border is the Arabah valley. The Negev has a number of interesting cultural and geological features. Among the latter are three enormous, craterlike makhteshim (box canyons), which are unique to the region; Makhtesh Ramon, Makhtesh Gadol, and Makhtesh Katan.

The Negev is a rocky desert. It is a melange of brown, rocky, dusty mountains interrupted by wadis (dry riverbeds that bloom briefly after rain) and deep craters. It can be split into five different ecological regions: northern, western, and central Negev, the high plateau and the Arabah Valley. The northern Negev, or Mediterranean zone, receives 300 mm of rain annually and has fairly fertile soils. The western Negev receives 250 mm of rain per year, with light and partially sandy soils. Sand dunes can reach heights of up to 30 metres here. Home to the city of Beersheba, the central Negev has an annual precipitation of 200 mm and is characterized by impervious soil, allowing minimum penetration of water with greater soil erosion and water runoff. The high plateau area of Ramat HaNegev (Hebrew: רמת הנגב‎, The Negev Heights) stands between 370 metres and 520 metres above sea level with extreme temperatures in summer and winter. The area gets 100 mm of rain per year, with inferior and partially salty soils. The Arabah Valley along the Jordanian border stretches 180 km from Eilat in the south to the tip of the Dead Sea in the north. The Arabah Valley is very arid with barely 50 mm of rain annually. It has inferior soils in which little can grow without irrigation and special soil additives.
