the camel is known to be a multipurpose animal able to produce milk, meat, wool, hides and skins, to be used for riding, agricultural activities, packing and carting, racing and many cultural events. the present paper aims to propose an analysis of the situation of camel studies worldwide and of the main trends since 1961 up to 2014. the main field involved the camel sciences and some remarks o...

Due to the unsustainable consumption of resources and climate change, it is increasingly difficult maintain security water–energy–food nexus, especially in regions with low availability. Thus, need design more resilient systems key sustainable development. Quantifying resilience integrated such as nexus a useful way identify vulnerable areas system thereby take corrective actions reduce inciden...

Objective: Soil salinity is one of the major worldwide environmental constraints affecting agricultural production in arid and semiarid regions. Lack of proper management of water and soil resources lead to increase soil salinity and reduce soil fertility. On the other hand, it seems simple and cheap method of measuring soil salinity is necessary. The aim of this study was to determine the rela...

water deficit is one of the most important problems facing crop production in arid and semiarid regions in iran. application of super absorbent polymers may somehow control yield reduction in some crop plants under drought stress conditions. in this investigation, the effect of different levels of super absorbent polymer, superab a200 (0, 100, 200, 300 kg/h), and three irrigation intervals (7, ...

Water drives the functioning of Earth's arid and semiarid lands. Drylands can obtain water from sources other than precipitation, yet little is known about how non-rainfall water inputs influence dryland communities and their activity. In particular, water vapor adsorption--movement of atmospheric water vapor into soil when soil air is drier than the overlying air--likely occurs often in drylan...

In semiarid climates, a significant component of recharge to basin aquifers occurs along the mountain front. Traditionally called “mountain-front recharge” (MFR), this process has been treated by modelers of basins as a boundary condition. In general, mountain-front recharge estimates are based on the general precipitation characteristics of the mountain (as estimated, e.g., by the chloride mas...
