Ancient Agriculture in the Negev Archeological studies and experimental farms show how agriculture was possible in Israel's famous desert. M. Evenari, L. Shanan, N. Tadmor, Y. AharoniThe Negev desert of Israel, with its numerous, clearly visible traces of an? cient civilizations dating back at least four to five thousand years, has attracted the attention of many scientists. Since Palmer (7) in 1871 described the general character of these civiliza? tions as well as the intriguing agricul? tural remnants that he observed in the area, the Negev has become a field of research for many phases of science.We have been working as a team in the Negev desert for five years with the specific aim of solving the enigma of the once flourishing agricultural civili? zations in a now barren desert. This team covers the fields of botany, archeology, ecology, hydrology, and water engineering, and this combination of experience and interests enabled us to correlate widely differing fields of observation.In this article we present some of our conclusions as to how the ancient civilizations maintained a thriving agriculture in the desert and also indicate their possible application in the future. Description of the area. The Negev Dr. Evenari is professor of botany at the Hebrew University, Jerusalem, Israel; Mr. Shanan is a hydrological engineer in Tel Aviv; Dr. Tadmor is a plant ecologist with the Ministry of Agriculture of Israel; and Dr. Aharoni is an instructor in the department of archeology of the Hebrew University, Jerusalem. 31 MARCH 1961 is shaped like a triangle (Fig. 1). Its base line stretches in the north from an imaginary line drawn from Gaza on the Mediterranean Sea, through Beer Sheva, to Ein Gedi on the Dead Sea. Its two sides stretch from Gaza and from Ein Gedi down to Eilat on the Gulf of Aqaba. The 12,500 square kilometers of the Negev can be divided into the six following subregions: (i) the coastal strip; (ii) the lowlands and foothills; (iii) the central highlands; (iv) the sedimentary southern Negev, mostly consisting of rolling gravel plains; (v) the crystalline southern Negev representing the northeast corner of crystalline Sinai; and (vi) the Wadi Araba depression. The physiographic and climatic con? ditions vary from subregion to subregion, and the various civilizations naturally adapted their agricultural projects to these differing features. The densest settled areas have been discov? ered in the lowlands and the highlands, and since most of our investigations have been concentrated in these sub? regions, we will describe them briefly. The lowlands and foothills. This sub? region is a strip about 10 to 25 kilo? meters wide, bounded by the coastal region on the west and the central highlands on the east and covering about 150,000 hectares. The morpho-logical structure is made up mostly of Eocene limestone hills separating wide rolling plains, with the elevations rang? ing from 200 to 450 meters above sea level. This area contains the ancient towns of Nessanah, Sbeita, Ruheibeh, and Khalassah. A number o...
