Natural and anthropogenic causes jointly lead to land degradation eventually desertification, which occurs in arid, semiarid, dry subhumid areas. Furthermore, extended drought periods may cause soil exposure erosion, and, finally, desertification. Several climatic, geological, hydrological, physiographic, biological, as well human factors contribute This paper presents a methodological procedur...

In this paper a survey on the garrigue vegetation dominated by Satureja montana subsp. occurring in Alta Murgia National Park is presented. These communities were compared with those of Ionian Arc ravines. Syntaxonomic, structural, chorological and ecological analyses performed order to achieve proper classification vegetation. A new association here described, Rhamno saxatilis-Saturejetum mont...

climate is a natural resource that effects decision making for selection of destinations in tourism and ecotourism. therelationship between climate and tourism is a complex one. but application of a climate index provides an ideal approachto understanding this complexity and is a useful tool for the tourism industry. in this study, a modified version ofmieczkowski's (1985) tourism climate index...

Twenty-three thousand four hundred eighty-four beef carcasses were classified according to the Mexican norm NMX-FF-078-SCFI-2002 at the No. 51 Federal Inspected Type abattoir located in the State of Tabasco, Mexico, owned by the Beef Cattle Union of Tabasco State.

Abstract. The Red River is one of the largest contributing sources discharge and nutrients to world's 10th freshwater lake, Lake Winnipeg. Conversion large areas annual cropland perennial forage has been proposed as a strategy reduce both flooding nutrient export Such reductions could occur either via reduction in concentration runoff or through changes basin-scale hydrology, resulting lower wa...

abstract soil temperature is one of the key parameters affecting most hydrologic and agricultural processes. therefore, its measurement and prediction is very crucial. so far, the statistical regression methods have been used for estimation of soil temperature for specific location encountering with lack or shortage of data. in this work, soil temperature data are estimated at six different dep...

Many model applications suffer from the fact that although it is well known that model application implies different sources of uncertainty there is no objective criterion to decide whether a model is suitable for a particular application or not. This paper introduces a comparative index between the uncertainty of a model and the change effects of scenario calculations which enables the modelle...
