Abstract Sand dunes are considered one of the most obstacles that face the horizontal or vertical expansion of agriculture in the desert. Sand dunes are a collection of a loose grouping of sand on the land surface in the form of a pile with top. In the recent years, increasing attention has been taken to cultivate the timber trees and ornamental plants in a narrow range to combat the desertification, sand encroachment and sand dunes. The climate factors are characterized by high temperature, strong winds laden with sand and sandy dunes, lead to soil erosion and remove the fertility soil in the surface layer, and destroying cultivated lands. Therefore, it's important to planting windbreaks and stabilization sand dunes to reduce the damage and loss of all areas of development aspects. The methods used for combating the sand dunes can be classified into two types; biological methods or plant measure and the second are the mechanical methods or engineering measure. We will focus in this article on the biological methods where the trees, shrubs and grasses are planted. -

Understanding the Causes of Bush Encroachment in Africa: the Key to Effective Management of Savanna Grasslands
Tropical Grasslands – Forrajes Tropicales (2013) Volume 1, 215−219 Understanding the causes of bush encroachment in Africa: The key to effective management of savanna grasslands OLAOTSWE E. KGOSIKOMA1 AND KABO MOGOTSI2 1Department of Agricultural Research, Ministry of Agriculture, Gaborone, Botswana. www.moa.gov.bw 2Department of Agricultural Research, Ministry of Agriculture, Francistown, Botswana. www.moa.gov.bw Keywords: Rangeland degradation, fire, indigenous ecological knowledge, livestock grazing, rainfall variability. Abstract The increase in biomass and abundance of woody plant species, often thorny or unpalatable, coupled with the suppres- sion of herbaceous plant cover, is a widely recognized form of rangeland degradation. Bush encroachment therefore has the potential to compromise rural livelihoods in Africa, as many depend on the natural resource base. The causes of bush encroachment are not without debate, but fire, herbivory, nutrient availability and rainfall patterns have been shown to be the key determinants of savanna vegetation structure and composition. In this paper, these determinants are discussed, with particular reference to arid and semi-arid environments of Africa. To improve our current under- standing of causes of bush encroachment, an integrated approach, involving ecological and indigenous knowledge systems, is proposed. Only through our knowledge of causes of bush encroachment, both direct and indirect, can better livelihood adjustments be made, or control measures and restoration of savanna ecosystem functioning be realized. Resumen Una forma ampliamente reconocida de degradación de pasturas es el incremento de la abundancia de especies de plan- tas leñosas, a menudo espinosas y no palatables, y de su biomasa, conjuntamente con la pérdida de plantas herbáceas. En África, la invasión por arbustos puede comprometer el sistema de vida rural ya que muchas personas dependen de los recursos naturales básicos. -

Sand Dune Stabilization and Reclamation in Southeastern Colorado
Sand Dune Stabilization And Reclamation In Southeastern Colorado Mike Scharp Parker Ag Services, LLC 4570 Kashmire Drive Colorado Springs, CO 80920 ABSTRACT This paper will discuss how and why Enviro-Gro Technologies (EGT) developed a large- scale sand dune reclamation program using New York City biosolids. The biosolids were applied during the winter of 1992 and 1993. The application site is located about 25 miles east of Lamar, CO and is comprised of 258 acres. Reclamation of the site resulted in its stabilization because vegitation was established on the site thus eliminating the encroachment into other areas. Based upon experience and negotiation with the Colorado Department of Public Health and Environment (CDPH&E) and the United State Environmental Protection Agency (USEPA) an application rate of 30 dry tons per acre was permitted. In addition, 10 dry tons per acre of woodchips were co-applied. The intent was that the excess carbon would bind some of nitrogen on the site and thus limit the amount of nitrogen that would leach from the site. Although data indicates that alternative application rates of 10 and 20 dry tons per acre of biosolids were applied for demonstration purposes, little data exist regarding these parcels. Therefore, this paper will deal with the main part of the site where 30 dry tons per acre of biosolids was applied. BACKGROUND Enviro-Gro Technologies began April 22, 1992 applying New York City biosolids near Lamar, CO. Typically about 150 wet tons of biosolids were land applied on privately owned dry land winter wheat. The average application rate was of 2.0 dry tons per acre. -
Quelques Aspects Problematiques Dans La Transcription Des Toponymes Tunisiens
QUELQUES ASPECTS PROBLEMATIQUES DANS LA TRANSCRIPTION DES TOPONYMES TUNISIENS Mohsen DHIEB Professeur de géographie (cartographie) Laboratoire SYFACTE FLSH de Sfax TUNISIE [email protected] Introduction Quelle que soit le pays ou la langue d’usage, la transcription toponymique des noms de lieux géographiques sur un atlas ou un autre document cartographique en particulier ou tout autre document d’une façon générale pose problème notamment dans des pays où il n’y a pas de tradition ou de « politique » toponymique. Il en est de même pour les contrées « ouvertes » à l’extérieur et par conséquent ayant subi ou subissant encore les influences linguistiques étrangères ou alors dans des régions caractérisées par la complexité de leur situation linguistique. C’est particulièrement le cas de la Tunisie, pays méditerranéen bien « ancré » dans l’histoire, mais aussi bien ouvert à l’étranger et subissant les soubresauts de la mondialisation, et manquant par ailleurs cruellement de politique toponymique. Tout ceci malgré l’intérêt que certains acteurs aux profils différents y prêtent depuis peu, intérêt matérialisé, entre autres manifestations scientifiques, par l’organisation de deux rencontres scientifiques par la Commission du GENUING en 2005 et d’une autre août 2008 à Tunis, lors du 35ème Congrès de l’UGI. Aussi, il s’agit dans le cadre de cette présentation générale de la situation de la transcription toponymique en Tunisie, dans un premier temps, de dresser l’état des lieux, de mettre en valeur les principales difficultés rencontrées en manipulant les noms géographiques dans leurs différentes transcriptions dans un second temps. En troisième lieu, il s’agit de proposer à l’officialisation, une liste-type de toponymes (exonymes et endonymes) que l’on est en droit d’avoir par exemple sur une carte générale de Tunisie à moyenne échelle. -

Bush thinning operations on three freehold farms Restoration were assessed to examine the response of local ungulates (small, medium, large) and predators (meso, large). Carrying capacity Camera traps were used to capture wildlife in bush encroached and previously thinned habitats. We hy- Overgrazing pothesized that thinning would increase the activity of small, medium, and large ungulates, meso and large Bush thinning predators, and that the magnitude of the increase in activity at thinned sites would differ among animal types. Our results revealed that the expected animal captures were not equal – small, medium, and large ungulates were common, large predators were least common; thinned areas had more expected animal captures and overall animal-treatment interactions were almost significant (p = 0.051). -
