the main factors affecting environmental sensitivity to degradation are soil, vegetation, climate and management, through either their intrinsic characteristics or by their interaction on the landscape. different levels of degradation risks may be observed in response to particular combinations of the aforementioned factors. for instance, the combination of inappropriate management practices an...

11 Large biases associated with climate projections are problematic when it comes to 12 their regional application in the assessment of water resources and ecosystems. Here, we 13 demonstrate a method that can reduce systematic biases in regional climate projections. 14 The global and regional climate models employed to demonstrate this technique are the 15 Community Climate System Model (CCSM)...

extended abstract 1. introduction human life is highly dependent on the environment and the services that are provided by the environment. environmental quality is a set of properties and characteristics of the environment, either generalized or local, as they may also impinge on human beings and other organisms. it is a measure of the condition of an environment relative to the requirements of...

Despite overwhelming scientific evidence for man-made climate change, many people and more importantly policymakers still remain skeptical about the subject. While this phenomenon of ”climate-skepticism” prevents implementation of environmental policies around the globe, it is ignored in economic models of climate change. In this paper we fill this gap by creating a model that allows for climat...

climate change phenomenon is an important environmental challenge of the world. increasing extension of greenhouse gases and remote relationship phenomena accelerate the speed f climate change. changes in precipitation level, drought occurrence and changes in the level of surface and groundwater resources are the recognized consequences of climate change. in order to study consequences of clima...

combating desertification which is a serious threat for the environment and human welfare requires understanding complex issues of this phenomenon using evaluation, awareness of severity of it's processes and determination of it's factors. so here, after recognizing the characteristics of the region showing existence desertification, we assess its current status with emphasis on clima...
