Public ISBD Titre de série : Environmental Conservation, 1 Titre : The euphrates river - an international problem of water resources development Type de document : texte imprimé Auteurs : Beaumont, P. Année de publication : 1978 ISBN/ISSN/EAN : CI-06283 Note générale : The watershed of the river euphrates lies within the boundaries of the present-day states of turkey, Syria, Irag, and Saoudi-Arabia. Almost 90 per cent of the runoff from the basin is generated within the higlands of eastern Turkey as the result of now-melt occuring during late spring aind early summer. At this time, flood levels one usually reached along the whole length of the river. The former inhabitants of the flood plain lands of Iraq utilized the waters of the rivers euphrates for at least 6, 000 years. By so doing, empires dependent upon irrigated agriculture flourished and then decayed, leaving behind spectacular ruins practically throughout Mesopotemia.

The world map of desertification, called for by the United Nations general assembly, delimates areas at risk of desertification as determined by bioclimatic stress, the inherent vulnerability of the land, and pressure of land - use. Areas of very high desrtification hazard are shown to be those arid and semi - arid regions with very heavy peassure of land - use. The threat of desertification is shown to be highest bey and the margins of the full deserts, but the risk extends wherver drought marks the seasonal or periodic extension of aridity.

Environmental Conservation. The expanding Sahara / Cloudsley-Thompson, J. L.

Public ISBD Titre de série : Environmental Conservation Titre : The expanding Sahara Type de document : texte imprimé Auteurs : Cloudsley-Thompson, J. L. Année de publication : 1974 ISBN/ISSN/EAN : CI-06823 Note générale : the belts of Savana lying to the south of the Sahara are described. Evidence is then presented which suggests that these have been created from forest by shifting cultivation and the use of fire : they have probably developed contemporaneously with the evalution of Man and increase in human population. The effect of climatic changes in creasing desert are discussed and the conclusion in reached that present conditions in much of the Sahara have been engendered almost entirely by human activities.
