Drought stress caused by unpredictable precipitation poses a major threat to food production worldwide, and its impact is only expected to increase with the further onset of climate change. Understanding the effect of drought stress on crops and plants' response is critical for developing improved varieties with stable high yield to fill a growing food gap from an increasing population dependin...

year. Other than continued replenishment of aquifers in the southeast, Australia reversed course from 2010, becoming wetter in the west and dryer in the northeast. Drought in equatorial Africa and recovery from drought in the Indochinese peninsula also stand out. Aquifers in central California (Famiglietti et al. 2011) and northern India (Rodell et al. 2009; Tiwari et al. 2009), which are stres...

The standard suite of indicators currently used in operational drought monitoring reflects anomalous conditions in several major components of the hydrologic budget—representing deficits in precipitation, soil moisture content, runoff, surface and groundwater storage, snowpack, and streamflow. In principle, it is useful to have a diversity of indices because drought can assume many forms (meteo...

Drought events and the overexploitation of freshwater resources have led to the increased need to manage groundwater reserves. Aquifer storage and recovery (ASR), whereby artificial water is injected into aquifers for storage, is one of the proposed methods by which freshwater supplies can be increased. Microbial clogging following injection, however, is a major issue. Here, during laboratory s...

The purpose of the present study was the simulation of climate change effects on groundwater resources in Iran by using the dynamic systems approach. The approach was performed through system dynamics modeling process including problem explanation, system description, model development, model testing, and the use of the model for policy analysis. The impact of the application of various exogeno...

While governments and individuals strive to maintain the availability of high-quality water resources, many factors can "change the landscape" of water availability and quality, including drought, climate change, saltwater intrusion, aquifer depletion, population increases, and policy changes. Specialty crop producers, including nursery and greenhouse container operations, rely heavily on avail...

Abstract Particularly in arid and semiarid areas, more populations rely almost entirely on imported water. However, the extent to which intentional discharge into transiting river systems unintentional leakage may be augmenting water resources for communities along down gradient of transfer scheme has not previously been subject research. The objective this study was assess both potential a lar...

The agricultural sector is of particular importance in the city of Bijar. Thus, the economic value perunit of water applid to the side effects of excessive groundwater resources in this area has a utmostimportance. Payment for estimation of water on a suitable production function was estimated revenueproducers. Therefore in this study to estimate the economic value of water resources in agricul...
