Soil moisture scarcity has become the major limiting factor of vegetation restoration in the Loess Plateau of China. The aim of this study is: (i) to compare the spatial distribution of deep (up to 5 m) soil moisture content (SMC) beneath the introduced shrub Caragana korshinskii Kom. under different precipitation zones in the Loess Plateau and (ii) to investigate the impacts of environmental f...

The present study aimed at evaluating differences in rotifer distribution in three estuarine zones in an inverse estuary located in the Semiarid Region of Brazil. Zones were chosen based on their proximity to the ocean and river border as a means of reflecting a horizontal salinity gradient. High freshwater discharge during the rainy season was the major determinant of rotifer composition. On t...

Abstract The development of societies and the increasing growth recent constructions, especially in cities, have caused environmental issues, destruction, reduction natural resources environment, green green-blue spaces. According to studies, past years, many parts even pristine surfaces spaces big cities been turned into artificial, impermeable spaces, which has aggravated ecological problems ...

Sustainable water use is one of the greatest challenges of irrigated agricultural systems. This study presents the results related to the agronomic and physiological response to the deficit irrigation of almond trees (Prunus dulcis DA Webb Mill cv. Guara) under semiarid Mediterranean conditions in the Guadalquivir river basin (SW Spain). Two deficitirrigation strategies were tested: i) regulate...

As we wrote in the summary of this special issue, purpose Special Issue is to report, more detail, research water resources management frame sustainable development [...]

The large-scale reuse of untreated domestic sewage for irrigation is commonplace in many arid and semiarid zones of Latin America, as a result of increasing population pressures, water shortages, and protein shortfalls. Twenty per cent of the land is arid or semiarid, having only 5% of the water resources of the Region; but this land supports 60% of the population (367 million people in 1983-I)...

The dromedary camel is a multipurpose animal adapted to the harsh environments of semiarid and arid zones, essentially kept for milk and meat production and transportation. It is also a financial reserve (asset) and security (drought-prone risk management) for pastoralists and plays an important role in social prestige and wealth (8, 19). Because of the increasing desertification and recurrence...

The amount and spatial distribution of deep drainage (downward movement of water across the bottom of the root zone) and groundwater recharge affect the quantity and quality of increasingly limited groundwater in arid and semiarid regions. We synthesize research from the fields of ecology and hydrology to address the issue of deep drainage in arid and semiarid regions. We start with a recently ...
