on one hand, iran due to the low annual rainfall and lack of appropriate spatial and temporal distribution in precipitation is considered as an arid and semi-arid country experiencing stress and water scarcity; on the other hand, 90% of annual water consumption has been allocated to agriculture sector in iran and efficiency and productivity of water consumption do not enjoy favorable status in ...

Climate-change-induced freshwater shortage and saline intrusion have been posing significant risks to agricultural sectors in arid semi-arid regions, negatively impacting irrigation, crop yield, food production. Climate-smart sustainable solutions are the requirement combat these major concerns. To overcome scarcity, pressure-driven desalination techniques used that require advanced operational...

On July 17, 2003, the National Bureau of Economic Research announced that the United States economy had troughed in November 2001 following the peak in March 2001. This makes the 2001 recession one of the shortest in U.S. history being only eight months in length. Whereas business cycles are defined in terms of the overall economies the authors of this paper investigate whether this national re...

Soil and water are the two most important basic factors for ensuring sustainable agricultural production. On other hand, supplying quality sufficient irrigation from nature production is getting harder day by day. The decrease or pollution of natural resources irrigated agriculture, especially in arid semi-arid climatic regions, necessitates making agriculture with use low-quality water. Low-qu...

plant biomass is an important factor for determining arid and semi-aridrangelands capacity. due to the lack of proper and annual sampling of rangelands, there areno suitable data to determine biomass, range condition and proper range managementoperations. plant biomass is one of the measurable attributes that can be assessed inrangeland studies. since the clip and weight method is destructive a...

BACKGROUND The semi-arid environments harbor nearly 40% of biodiversity, and half of indigenous cultures of Mexico. Thousands of communities settled in these areas depend on agriculture and using wild biodiversity for their subsistence. Water, soil, and biodiversity management strategies are therefore crucial for people's life. The tajos, from Sierra Gorda, are important, poorly studied, biocul...

Few studies have investigated the influence of water availability on plant population spatial patterns. We studied changes in the spatial patterns of Caragana stenophylla along a climatic drought gradient within the Inner Mongolian Plateau, China. We examined spatial patterns, seed density, "nurse effects" of shrubs on seedlings, transpiration rates and water use efficiency (WUE) of C. stenophy...
