prosopis cineraria (l.) druce (kahour in persian) is a native and indicative species of saharo-sindian region. prosopis forest in iran extends from the beach of persian gulf and oman sea in boushehr, hormozgan and sistan-baluchistan provinces to south of kerman province. in this research ecological conditions of prosopis such as floristic diversity, climate, soil and the biomass were studied. i...

Mineral deficiencies that lead to production losses often occur concurrently with climatic and management changes. To diagnose these deficiencies in time to prevent production losses, long-term monitoring of mineral status is advisable. Different classification systems were examined to determine whether areas of possible mineral deficiencies could be identified, so that those which were promisi...

The Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue (DB) algorithm was developed for aerosol retrieval on bright surfaces. Although the global validation accuracy of DB product is satisfactory, there are still some regions found to have very low accuracy. To this end, has updated surface database in latest version Collection 6.1 (C6.1) algorithm. Some studies shown that optical ...

The amount and spatial distribution of deep drainage (downward movement of water across the bottom of the root zone) and groundwater recharge affect the quantity and quality of increasingly limited groundwater in arid and semiarid regions. We synthesize research from the fields of ecology and hydrology to address the issue of deep drainage in arid and semiarid regions. We start with a recently ...

Relatively little research has been expended on developing plants for use in urban desert landscapes or “xeriscapes.” However, because of reduced availability and increased cost of water, water conservation needs, and concerns for our environment, increased awareness and demand for arid-adapted landscape plants have developed. An especially important need is for groundcover requiring little wat...

desertification is the consequence of series of processes in which climate change and human activities are more important factors than others. arid and semi-arid areas have occupied most parts of iran. sistan region is one of arid areas of iran where wind erosion is an important factor of land degradation and soil deterioration. for classification of desertification intensity, several methods h...
