Contamination of soil and water due to the release of light non-aqueous phase liquids (LNAPLs) is a ubiquitous problem. The problem is more severe in arid and semi-arid coastal regions where most of the petroleum production and related refinery industries are located. Biological treatment of these organic contaminated resources is receiving increasing interests and where applicable, can serve a...

Forests have evolved in their natural ecosystems over millennia to become the world’s most important and valuable renewable resources. Genetic variety perspective trees has been defined as Forest Resources (FGRs). genetic resources directly or indirectly sustain human livelihoods provide raw materials for various forest-based enterprises. This chapter focuses on FGRs of arid semiarid regions, w...

differentiation among populations of the iranian teucrium polium l.was analyzed on the basis of morphological and phytochemical variability, to evaluate the level and distribution of diversity among four distant populations from arid, semi-arid, and sub-humid regions of fars province. morphological analysis included 11 characters related to the plant, leaf, and stem morphology. analyses of vari...

a two-year field experiment was carried out in semi-arid region of southern iran (shiraz), during 2007-2008 and 2009-2010 growing seasons using various mixtures of an early- (cv falat) and a middle-ripening (cv shiraz) winter wheat cultivar to evaluate the beneficial effects of inducing temporal growth heterogeneity on reduction of intra-specific competition during post-anthesis moisture stress...

this research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. this experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of chenran township. the results ...

The objective of this paper is to provide an overview of the primary results of the Semi-Arid Land–Surface–Atmosphere (SALSA) Program in the context of improvements to our overall understanding of hydrologic, ecologic, and atmospheric processes and their interactions in a semi-arid basin. The major findings and future research needs associated with the different core components of the program a...

The “counter-trend” of oasification in China’s arid and semi-arid regions has attracted widespread attention against the backdrop rising global desertification risk, which endangers ecological safety food security. This paper selects pertinent literature from CNKI WoS core collection databases then uses bibliometric methods to comb current status, key contents, cutting-edge trends research. fol...
