Remote sensing is collection of data from earth surface features without physical contact. It may include aerial photos and satellite imagery. The great advantage of satellite images is that data avai...
APPLICATION OF ETM+ DATA FOR ESTIMATING RANGELANDS COVER PERCENTAGE
ETM+ Vegetation indices Fusion Percentage vegetation cover Correlation analysis Stepwise regression
2015/5/27
The major land cover in Iran is rangeland, so it is not possible to assess the vegetation cover of these vast areas through field work. During the recent years, many researchers have used various sate...
Conventional tillage versus organic farming in relation to soil organic carbon stock in olive groves in Mediterranean rangelands (southern Spain)
Conventional tillage organic farming soil organic carbon stock olive groves Mediterranean rangelands
2015/1/6
Soil organic carbon (SOC) concentration is a soil variable subject to changes. The management system is a key factor that influences these changes. To determine the long-term effects of the management...
Nutritive Value of Grasses in Semi-arid Rangelands of Ethiopia: Local Experience Based Herbage Preference Evaluation versus Laboratory Analysis
Semi-arid Rangelands Spatial Variation in Feed Quality
2016/5/11
We examined the nutritive value of common grass species in the semi-arid rangelands of Borana in southern Ethiopia using local experience based herbage preference (LEBHP) perception and laboratory tec...
DEVELOPMENTS IN MONITORING RANGELANDS USING REMOTELY-SENSED CROSS-FENCE COMPARISONS
Agriculture Environment Land Use GIS Landsat Land Cover Monitoring
2014/4/30
This paper presents a new method for the use of earth-observation images to assess relative land condition over broad regions, using a cross-fence comparison methodology. It controls for natural spati...
Monitoring of Net Primary Production in California Rangelands Using Landsat and MODIS Satellite Remote Sensing
Grasslands MODIS Landsat California Net Primary Production
2013/3/8
In this study, we present results from the CASA (Carnegie-Ames-Stanford Approach) model to estimate net primary production (NPP) in grasslands under different management (ranching versus unmanaged) on...
Importance of annual and seasonal precipitation variations for the sustainable use of rangelands in semi arid regions with high altitude
Precipitation standard precipitation index drought rangeland
2011/1/12
Precipitation is one of the most important factors which can determine the type and productivity of rangeland vegetation in arid and semi arid regions. In the present study, a widely used drought anal...

The objective of the current study was to determine seasonal changes in glucose, cholesterol, non-esterified fatty acids (NEFA), serum inorganic phosphorous (SIP), calcium, magnesium and iron concentr...
Protein Status of Indigenous Nguni and Crossbred Cattle in the Semi-arid Communal Rangelands in South Africa
Albumin Alanine Aminotransferase Aspartate Aminotransferase Globulin Creatinine Urea
2016/5/4
The objective of the current study was to determine factors influencing concentrations of protein-related blood metabolites in indigenous Nguni and crossbred cattle in the semi-arid communal rangeland...
Pilot Study for an Assessment of Vegetation Structure for Steppe Rangelands of Central Anatolia
Semiarid steppe-rangelands vegetation-pattern Central Anatolia Redundancy Analysis
2009/1/7
In the last 50 years, rangelands in the Central Anatolian Region of Turkey have been converted to cropping lands, which has negatively accelerated vegetation change, resulting in overgrazing and poor ...
