Soil degradation induced by gully erosion represents a worldwide problem in the many arid and semi-arid countries, such as Iran. This study assessed: (1) importance of variables that control using Boruta algorithm, (2) relationship among causative gullied locations evidential belief function model (EBF), (3) development algorithms boosted regression tree (BRT) support vector machine (SVM). Base...

Urbanism directly affects the hydrological cycle. One of the ways to manage runoffs in urban areas that is considered nowadays is green roof creation. Green roof is mainly created in humid and semi-humid areas, and efficiency of green roofs in arid and semi-arid areas has attracted less attention. In the current study, to evaluate the effect of green roof in arid and semi-arid to reduce runoff,...

fire is one of the incorporate vegetation management practices for grasslands and semi-arid rangelands. it may affect symbiotic relationship between range plants and mycorrhiza. accordingly, this research was aimed to investigate the effects of a spring prescribed fire on the symbiotic relationships between mycorrhiza and 6 plant species. the study was conducted in a semi-arid steppe rangeland ...

the effects of different climatic, soil, geometric, and management factors on soil organic carbon (soc) degradation and sequestration potential was evaluated in the semi-arid zone of mereg watershed, west of iran. two nonparametric methods, viz. classification and regression tree (cart) and feed forward back propagation artificial neural network (ann) were compared with parametric multivariate ...

salinity and flooding are as two very important factors of soil degradation. they often occur together and cancause severe damage to plants. however, plant response to environmental stresses may vary with growth stage atwhich exposure occurs. a pot study was conducted in 2005-2006 in northern aq qala (northern iran) to studycombine effects of waterlogging and soil salinity at different growth s...

The importance of equity has been emphasized in climate change, biodiversity loss, land degradation, and ecosystem restoration. However, implications are rarely considered explicitly restoration projects. Although the role studied context conservation environmental governance, variables often ignored studies, spatial analyses lacking. To address these gaps, we use a mixed methods approach, inte...
