Geoinformation assessment of spatial data is carried out in order to establish the condition and location irrigated lands on territory Svetloyarsky District Volgograd region, as well their geomorphological characteristics using remote sensing data, digital terrain models, soil maps. The results study make it possible develop a system socio-economic measures for effective use agricultural land m...
On marginal lands in the Mediterranean basin, giant reed (Arundo donax L.) represents one of most interesting perennial crops due to high levels biomass production. Considering periodic water shortage during summer months this area, reuse treated wastewater (TWW) would seem be a good opportunity for growth species. The aim study was assess medium-term effects irrigation using freshwater (FW) an...
Extensive geographic areas of the world show a long-term atmospheric moisture deficit. Desertification Rajasthan is concurrent with strengthened weather extremality and mean annual air temperature (MAAT) rise over western part Indian subcontinent. The present landscape aridification due to precipitation decrease reinforced windiness generates surface-cover dryness, aeolian erosion mass sediment...
the growing population and increasing socio-economic necessitiescreates a pressure on land use/land cover. nowadays, land use change detection using remote sensing data provides quantitative and timely information for management and evaluation of natural resources. this study investigates the land use changes in part of hableh rood watershed of iran using landsat 7 and 8 (sensor etm+ and oli) i...

Soil salinization and sodification are common processes that particularly characterize drylands. These can be attributed either to natural conditions or anthropogenic activities. While causes include factors such as climate, lithology, topography, pedology, human mostly related agricultural land-use, specifically, irrigated agriculture. The objective of this study was thoroughly review topic, w...
