at the beginning of twenty-first century, the water crisis in the priority policy andmanagement is inside and outside of the country as principle thoroughly human, social,economic and political rulers of the country is considered abundant. the world bank hasannounced that during 1960 and 2025, water resources in middle east, from 3430 m3 for theeach person in year reach to 667 m3 because of pop...

Deciphering the sources of eolian dust on the Chinese Loess Plateau (CLP) is fundamental to reconstruct paleo-wind patterns and paleo-environmental changes. Existing datasets show contradictory source evolutions of eolian dust on the CLP, both on orbital and tectonic timescales. Here, the silicate Sr and Nd isotopic compositions of a restricted grain size fraction (28-45 μm) were measured to tr...

Agricultural crops take up water, but not salt, and evaporation from irrigated land does likewise. The result is increasing salt levels in soils. Just as cities cannot ignore urban wastewater collection and treatment, irrigating farmers and irrigation districts cannot ignore what to do with the salt in agricultural drainage water. Although salt management techniques can seem straightforward, th...

Inappropriate land use has caused a series of environmental disasters such as floods and sand storms, and some of them involved unused land changes with highly localized distributions in arid and semi-arid regions with fragile ecosystems. As the third-rank category of first-level land use/cover in China, unused land (UL) is now playing an increasingly important role in protection of the natural...

Algae are very large and diverse group of simple, typically autotrophic organisms that can carried out photosynthesis and have ability to capture energy from sunlight. Algae play an important role in sustainable and organic agriculture where it is used as biofertilizer and soil stabilizers. Algae, particularly the seaweeds, are used as fertilizers, resulting in less nitrogen and phosphorous run...

In arid and semi-arid lands, people eats many kinds of spices. Capsaicin is one effect active component of spices. Previously we demonstrated that capsaicin induced tight junction (TJ) opening in human intestinal Caco-2 cells. We showed that the increase of TJ permeability was involved in actin polymerization. However the underlying mechanisms are unclear. The major aims of this study were to d...

Gravely calcareous soils cover approximately most of arid lands (in percent); however, the solute transport behavior in these soils remains a current issue. This research aimed at estimating and correlating the solute transport parameters in gravely calcareous soils as being affected by different land uses through the knowledge of the soil morphological, physical, and chemical properties. Four ...
