Water resources globally face unprecedented challenges, but these are at their greatest in the world’s arid and semi-arid regions. Recent IPCC estimates (Kundzewicz et al., 2007) state that between 1.4 and 2.1 billion people live in areas of water stress; those numbers are expected to increase significantly under the pressures of population growth and climate change. By definition, arid and sem...

New vegetation in barren areas offers possibilities for sequestering carbon in the soil. Arid and semi-arid areas (ASAs) are candidates for new vegetation. The possibility of agriculture in ASAs is reviewed, revealing the potential for cultivation by covering the surface with a layer of organic fibres. This layer collects more water from humidity in the air than does the uncovered mineral surfa...

determination of the amount of sugar in sugar beet is usually accomplished by polarimetric method in sugar industry. this method is not accurate due to impurities such as sodium, potassium and amino-nitrogen that are present and might cause some errors in the evaluation of the technical quality of sugar beet. in this research, 7309 samples of sugar beet from two semi- arid county, isfahan and c...

salinity is a major environmental problem in arid and semi-arid areas. chickpea (cicer arietinum l.), like other legumes is sensitive to salinity. therefore, selection of genotypes to grow on saline areas is important. eleven chickpea genotypes (as sub plots) were grown in the greenhouse conditions on a medium containing different nacl concentrations (8 and 12 dsm-1) and control (hoagland solut...

     Roads have an important role in plants dispersal on different scales. Various plant species settle on roadsides, but some of them can enter the natural environments and threaten their biodiversity. Worldwide knowledge of roadside flora is necessary for local and global management of natural areas. Accordingly, the roadside flora of Northern Khorasan rangelands was studied along the 600 km ...

Hydrological processes and their spatial distribution directly are relevant to climate, topography, geology, and land use in the watershed. Therefore, use of a model whit integrity and high performance for simulating the process in deferent watersheds is very important. In this study was assessment performance of semi-distributed SWAT model in simulating hydrology processes in three watersheds ...

Abstract. From the perspectives of many environmental and conservative policy makers, improving and diversifying the livelihoods have been found as a mechanism to promote the livelihoods and persuade people to avoid the overexploitation and degradation of natural resources. Due to the fragility of the environment and inconsistency of incomes, the alternative income sources may be promised to wa...
