Application[Editor 321]  of biotic growth regulators (e.g. humic components) and appropriate mulches is recommended to improve turfgrass quality especially in arid andsemi-arid climate zones. However, limited number of studies have investigated their effect on lawn establishment. To investigate the effect of humic acid (HA) and selected mulches on characteristics of Festuca arundinacea in its p...

paper undertakes software based numerical simulations in two different traditional houses in cold-dry climate of tabriz and hot-arid climate of yazd, the eco test software chosen for bim simulations. case study on real houses instead of hypothetical models can give more tangible results and choosing traditional houses can provide a good opportunity to compare both physical and thermal condition...

The mid-latitudes of East Asia are characterized by the interaction between the Asian summer monsoon and the westerly winds. Understanding long-term climate change in the marginal regions of the Asian monsoon is critical for understanding the millennial-scale interactions between the Asian monsoon and the westerly winds. Abrupt climate events are always associated with changes in large-scale ci...

Drylands cover about 41% of the Earth’s land surface and are inhabited by more than two billion people, who rely on diversified ecosystem services provided drylands for their livelihoods. Achieving sustainable livelihoods (SLs) is a key component achieving development goals set agenda in 2030. Although it has aroused extensive interest, research SLs at regional scale still limited. This paper a...

Populus euphratica tree is a species naturally growing in riparian zones of rivers in arid and semiarid region where seasonal flooding and soil waterloging provides the conditions for this species. The aim of current study was to assess survival, growth characteristics and biomass allocation of Populus euphratica seedlings exposed to combined flooding- salinity stress at four levels including c...

Diffuse discharge along the southwest margin of the Great Artesian Basin is thought to be an important, but currently poorly understood, component of the Basin’s water budget. Remote sensing data are being investigated as a tool for mapping the salt and soil moisture variations associated with diffuse discharge zones, in order to assist in scaling up of field based discharge measurements to reg...

China launched the Three-North Shelterbelt Forest Program (TNSFP) in 1978 northern to combat desertification and dust storms, but it is still controversial ecologically fragile arid semi-arid areas, which partly due uncertainties of monitoring spatial-temporal changes forest distribution. In this study, we aim provide an overall retrospect (i.e., gain loss) during 2007–2017, analyze different p...
