Research ArticleOpen accessIn the abstractDETECTION OF LAND USE AND LAND COVER CHANGES IN DIRAB REGION OF SAUDI ARABIA USING REMOTELY SENSED IMAGERIESR. Madugundu, K. A. Al-Gaadi, V. C. Patil, E. TolaKnowledge of Land Use and Land Cover (LULC) changes is important for many planning and management activities. It is thought to be an essential element for modeling and understanding the major land forms, especially in arid regions like Saudi Arabia. This study investigates the LULC changes in Dirab region of Saudi Arabia between 1980 and 2010, using Landsat TM/ETM+images. After … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 30 Jan 2014 · 8,013 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrends in Maximum Daily Rainfall in Marginal Desert Environment: Signs of Climate ChangeKhaldoun A. Al-Qudah, Abdullah A. SmadiProblem statement: Change in intense precipitation has been used as an indicator for anticipated climate change. The trend in maximum daily rainfall in 10 rainfall stations distributed in the north and north east of Jordan has been investigated. Based on mean annual rainfall and geographic location, rainfall stations were divided into subhumid, semi-arid and arid stations. Approach: The regression approach … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 14 Sep 2011 · 7,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Geometry and Orientation on Flank Insolation of Streets in an Arid Climate CityMehrdad Mazloomi, Ahmad Sanusi Hassan, Parmis Naraghi Bagherpour, Mohd Rodzi IsmailProblem statement: Whilst at the design stage the various aspects of design impact must be taken into account, the incident solar radiation, insolation, is a key to many environmental aspects of street canyons. In this regard, the configuration of an urban street has a decisive role in magnitude of the solar radiation which it receives on its flank. This study … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 8,999 accessesView PDFCite
Research ArticleOpen accessIn the abstractDairy Heifer Rearing in Hot Arid Zone: An Economic AssessmentM. A. Razzaque, S. A. Mohammed, T. Al-MutawaProblem statement: Economic losses due to high mortality in young calves born in hot arid zone including Kuwait and a high cost of rearing are the main constraints to this region. Therefore, dairy producers have to depend on importation of pregnant heifers for herd replacement. Research data on cost of heifer rearing from their weaning to first lactation were lacking. … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,536 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Potassium Levels on Antioxidant Enzymes and Malondialdehyde Content under Drought Stress in Sunflower (Helianthus annuus L.)H. Soleimanzadeh, D. Habibi, M.R. Ardakani et al.Problem Statement: Drought stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses and ultimately lower crop productivity in arid and semi arid zones. Sunflower is one of the main oil seed crops in Iran, where drought stress is the most limiting factor. Drought stress tolerance requires the activation of complex … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,779 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysiological Response of Soybean (Glycine max) to Foliar Application of Methanol Under Different Soil MoisturesFarzad Paknejad, Mojtaba Mirakhori, Majid Jami Al-Ahmadi et al.Problem statement: Many cultivated area are situated in arid zone, where crop photosynthesis and productivity has limited by drought. Thus any treatment, such as methanol, that improve plant water relation and reduce stress impacts, could be benefit. Approach: In order to investigate effects of methanol application on some physiological properties of soybean under low water stress, a factorial experiment was … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractMountain Sheep: An Environmental Epidemiological Survey of Variation in Metal Exposure and Physiological Biomarkers Following Mine DevelopmentLawrence K. Duffy, Michael W. Oehler, R. Terry Bowyer, Vernon C. BleichProblem Statement: Anthropogenic activities, such as mining and industrial operations, are a major environmental source of metal exposure for wildlife. Quantitative data regarding biochemical effects of exposure to mineral extraction on mountain sheep, Ovis canadensis, are limited, although their habitats are becoming increasingly affected by expanded resource development. Decisions relating to environmental protection and wildlife conservation should be based on … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,654 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordResistance to Brown and Stem Rust in Spring Soft Wheat Varieties in the Arid Climate of Northern KazakhstanAdylkhan Babkenov, Sandukash Babkenova, Svetlana Dashkevich et al.To create competitive wheat varieties, it is essential to make active use of the world's diversity of genetic resources. The study aims to test the genetic resources of spring soft wheat for resistance to rust diseases. A spring soft wheat collection consisting of 206 samples, was studied in 2020-2022 for resistance to leaf and stem rust, as well as for … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 28 Aug 2023 · 5,023 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEvaluation of Soil Moisture Sensors under Intelligent Irrigation Systems for Economical Crops in Arid RegionsMohamed Said Abdall El Marazky, Fawzi Said Mohammad, Hussein Mohamed Al-GhobariProblem Statement: In irrigation water management, irrigation water use represents a substantial opportunity for agriculture water savings. Automation of irrigation systems, based on Soil Moisture Sensors Systems (SMSS) has the potential to provide maximum water use efficiency by maintaining soil moisture at optimum levels. Approach: The objective of this research was to evaluate the performance of soil moisture sensors under … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 24 Jun 2011 · 8,904 accessesView PDFCite
