Semi-arid ecosystems play a key role in global agricultural production, seasonal carbon cycle dynamics, and longer-run climate change. Because semi-arid landscapes are heterogeneous and often sparsely vegetated, repeated and large-scale ecosystem assessments of these regions have to date been impossible. Here, we assess the potential of high-spatial resolution visible band imagery for semi-arid...

     In the way of finding economic and tolerable plant to the arid and semi-arid climatic conditions and prevent desertification in these areas, this study aims to assess Agro-climatic suitability for producing Saffron in East-Azerbaijan province based on Geographic Information System (GIS) spatial analysis technique. For this goal, several criteria including soil conditions, climatological in...

Abstract Soil salinity has been recognized as the most serious problems for agriculture in arid and semi-arid areas of the world. To evaluate the changes in some  growth parameters  and chemical composition of two forage sorghum (Sorghum bicolor var. sudanense  lines (KFS1, KFS2) under salinity stress [0 (control), 3, 6, 9, 12 dS/m of sodium chloride], a pot experiment was carried out at Colleg...

Growth in the publication of scientific articles is occurring at an exponential rate, prompting a growing need to synthesise information in a timely manner to combat urgent environmental problems and guide future research. Here, we undertake a topic analysis of dryland literature over the last 75 years (8218 articles) to identify areas in arid ecology that are well studied and topics that are e...

Carbon uptake by terrestrial ecosystems is increasing along with the rising of atmospheric CO2 concentration. Embedded in this trend, recent studies suggested that the interannual variability (IAV) of global carbon fluxes may be dominated by semi-arid ecosystems, but the underlying mechanisms of this high variability in these specific regions are not well known. Here we derive an ensemble of gr...

abstract evapotranspiration as one of the important elements in agriculture has a considerable role in water resource management. therefore, using a more exact estimation method is an essential step of agricultural development, especially in arid semi-arid area. in this research, in order to exact estimate of garlic evapotranspiration using lysimeteric data, an artificial neural network (ann) m...
