land use may be regarded as one of the most important factors affecting theenvironment with respect to human activities. so far, destroying the rangelands andchanging them into the waste lands and poor rangelands has been proposed as the mostsignificant variations of land use done by human beings. this paper has been conducted toevaluate the variations of vegetation percentage and land uses in ...

Interferometric synthetic aperture radar (INSAR) has been used to map terrain topography; however, accuracy is limited because observations are not measurements of true surface topography over vegetated areas. Instead, the measurements, which depend on the sensor and the vegetation, represent some height above the true surface. We solve an inverse problem for INSAR scattering to determine surfa...

When choosing which environmental attributes to monitor in assessing disturbance, it is important to consider not onlywhichmetric will provide themost sensitive indicator of disturbance, but also the spatial considerations of where in the landscape thatmetric will bemost responsive to change.Degradation in landscapes is often unevenly expressed because: (i) disturbance is spatially localised, (...

Ilona Kickbusch’s thought provoking editorial is criticized in this commentary, partly because she fails to refer to previous critical work on the global conditions and policies that sustain inequality, poverty, poor health and damage to the biosphere and, as a result, she misreads global power and elides consideration of the fundamental historical structures of political and material power tha...

soil moisture is one of the critical parameters in climatic, ecological and hydrological modeling and vegetation growth. soil moisture is important for environmental studies but due to ground-based point measurement of soil moisture is expensive and impractical for watershed measurement, this parameter is not be used widely to simulate and predict models. overall and uniform view on different p...

Because remote sensing data can offer information on the geographical landscape of the earth’s surface, these data can be widely used in researching types of land and monitoring vegetation. In this paper, we discuss how to extract land types and vegetation from remote sensing data using the method of Non-Supervised Classification. These data provide the means to study types of soil and vegetati...
