  • Suitability of Different Awassi Lines for Efficient Sheep Production of Bedouins in the Negev in Israel
    Anna Al Baqain (Autor) Suitability of different Awassi lines for efficient sheep production of Bedouins in the Negev in Israel https://cuvillier.de/de/shop/publications/6107 Copyright: Cuvillier Verlag, Inhaberin Annette Jentzsch-Cuvillier, Nonnenstieg 8, 37075 Göttingen, Germany Telefon: +49 (0)551 54724-0, E-Mail: [email protected], Website: https://cuvillier.de INTRODUCTION CHAPTER 1 1 Introduction 1.1 Problem statement Only 16% of the area in the Middle-East is arable land (Dowling, 2009). The rest consists of marginal land and desert, used by Bedouins to raise livestock. Small ruminants are playing a major role in the Bedouin livestock production, representing one of their most important income sources. As pastoralists, Bedouins followed available resources of pasture with irregular movements, but country borders and settlement activities changed this lifestyle drastically in most areas of the Middle East. The compulsory schooling of children and governmental sedentarization programs have changed Bedouin lifestyle from nomadic to a more transhumant, or even settled one. Additionally, a decrease in resources of land and water, together with changing market conditions forced Bedouin sheep farmers to continuously adjust their production system and their respective inputs to market conditions. Abu-Rabia (1984) has found that several Bedouin sheep farms in the Negev face continuous economic losses. Especially in marginal areas it is thus very essential to choose the right type and quantity of input (Nudell et al., 1998) for an efficient production. In the Negev desert in Israel, tradition-oriented, extensive systems co-exist besides more intensified systems with a high market-orientation (Rummel et al., 2003).

  • Taxonomy and Ecology of the Lebanese Species of the Genus Hydraena KUGELANN, with Descriptions of Four New Species (Coleoptera: Hydraenidae)
    ©Wiener Coleopterologenverein (WCV), download unter www.biologiezentrum.at Koleopterologische Rundschau 76 97–134 Wien, Juli 2006 Taxonomy and ecology of the Lebanese species of the genus Hydraena KUGELANN, with descriptions of four new species (Coleoptera: Hydraenidae) M.A. JÄCH,A.DIA &J.A.DÍAZ Abstract Four new species of Hydraena s.str. KUGELANN are described from Lebanon: Hydraena (s.str.) berthelemyana, H. (s.str.) orthosia, H. (s.str.) phoenicia, and H. (s.str.) sidon. Ecological and distributional data of all nine Lebanese Hydraena species are summarized. All species are keyed. The male and female genitalia are illustrated. Key words: Coleoptera, Hydraenidae, Hydraena, new species, Lebanon. Introduction Since almost 30 years, the second author, A. Dia, has been co-ordinating comprehensive hydro- biological surveys in Lebanon. In the course of these surveys four new species of Hydraena KUGELANN were discovered, which are described herein. The large number of specimens sampled provided an opportunity to study the ecology and distribution of the Lebanese species of the genus Hydraena. Ecological and distributional data of all nine Lebanese Hydraena species are summarized. All species are keyed. The male and female genitalia are illustrated. Material and methods About 1100 adults of Hydraena from Lebanon were studied. The majority of these specimens were sampled by the second author in more than 10 coastal river systems along the western slope of Mt. Lebanon. In addition to the material sampled by the second author, we have examined all historical specimens (types of H. berytus JÄCH and H. furthi JÄCH) and a few specimens which were collected by R.

  • Effects of Grazing and Trampling on Soil Deterioration Around Recently Drilled Water Holes in the Sahelian Zone
    · )' r 6 Effects of grazing and trampling on soil deterioration around recently drilled water holes in the Sahelian Zone C. Valentin ! In 1937 Stebbing pointed out that drier climatic conditions were lead­ ing to the southward encroachment of the Sahara (20). His observations were almost immediately rejected by an Anglo-French commission, which argued that in most cases soil degradation was caused by the action of man (18). Because of the protracted drought of the 1970s in the Sahelian belt, Stebbing's caution recently was brought into sharp focus. According to many scientist~ overgrazing and trampling, especially near watering points, are the major causes of soil degradation and, consequently, deser­ tification of this area (6, 9, 13, 26). However, published material relating accelerated erosion to animal husbandry remains scarce. Additional in­ formation is essential. Scientific attention has focused on a large region of northern Senegal, which as recently as 30 years ago was called the "FerIo Desert." At that time, despite the continuous presence offodder, livestock were herded out of the area as ponds dried up after the rainy season. The Ferlo was thus deserted by nomadic herdsmen 9 months out of each year. Once numer­ , ,. ous deep wells were drilled in the 1950s, the seasonal migrations of no­ madic communities declined rapidly, and this region was subjected to permanent pastoralism. Such a radical change in pastoral practices affected many aspects of the human and natural environments. To document such changes, studies recently were carried out in that area. The area provided a large-scale ex­ perimental site for an interdisciplinary team composed of investigators of 51 EFFECTS OF GRAZING AND TRAMPLING ON SOIL DETERIORATION 53 52 C.
