Disentangling the relations between human migrations and water resources is relevant for food security and trade policy in water-scarce countries. It is commonly believed that human migrations are beneficial to the water endowments of origin countries for reducing the pressure on local resources. We show here that such belief is over-simplistic. We reframe the problem by considering the interna...
Background and Objective: Water quality assessment is an important step for optimal and proper use of water resources for drinking and selection of suitable and consistent water quality patterns. Therefore, the necessity of studying water quality characteristics in water resource management programs has been highly considered. Materials and Methods: In this study, the hydrogeochemical quality ...
water resources sustainability is one of the major issues in the agricultural sustainability. in this study sustainability of water resources has been investigated by use of linear and non-linear models in six models based on optimal utilization of water resources in the north parts farms of iran because of incorrect use of agricultural water resources, from 2011 to 2012. also “gross margin per...
The imbalance between water supply and demand in the country has challenged water resource management, especially in the agricultural sector. The virtual water study approach, as an approach that values the use of water inputs in the production and consumption of various commodities, has been established and discussed for almost two decades. Based on this concept, the issue of virtual water tra...
China is facing a water resources crisis with growing concerns as to the reliable supply of water for agricultural, industrial and domestic needs. High inter-annual rainfall variability and increasing consumptive use across the country exacerbates the situation further and is a constraint on future development. For water sustainability, it is necessary to examine the differences in water demand...
Contamination of water resources with pesticides residues becomes a pressing problem in Gaza due to the frequent application of pesticides in the intensive agricultural system. This study tests the potential of using organo-bentonite as a porous material to remove bromoxynil residues from contaminated water. Bentonite surfaces were activated for removal of bromoxynil residues from water by simp...
the scarcity of water resources and supply resources limitation, have caused an increasing gap between water supply and demand specially in recent decades in almost all regions of the globe. one of the best known solutions proposed by the economists is using the different water pricing approaches thereby obtaining the optimal allocation and social justice. to this purpose, this paper uses the p...
Traded agricultural goods redistribute water, virtually, around the world to satisfy unmet demands while limiting excess water extraction in importing regions. However, gaps remain our understanding of how alternative international trade regimes may alter demands, locally and virtually. Here, we explore global savings virtual impacts such under reference low-carbon scenarios using an integrated...
The availability of good quality water resources is essential to ensure healthy crops and livestock. The objective of this study was to evaluate the level of pollution in Bustillos Lagoon in northern Mexico. Physical-chemical parameters like sodium, chloride, sulfate, electrical conductivity, nitrates, and the pesticide dichlorodiphenyltrichloroethane (DDT) were analyzed to determine the water ...
