Water is the first and foremost limiting factor for agricultural production, and undoubtedly, water crisis is considered as one of the international challenges for governments and human societies. Given that virtual water was first used as a way to tackle water scarcity in countries with limited water resources, so that countries with low water should import food from abundant countries...

shortage of water resources and increasing demand to consumption of this scarce resource, leads to somenoticeable limitations. on the other hand, population growth and consequently, increasing demand for water in aridand semi arid regions , needs production in exchange of little amount of water consumption. to approach thisobjective, an experiment in the complete randomized blocks carried out i...

considering importance and the role of forecasting water consumption in water resources management and implementing appropriate short- and long-run policies in order to optimize water demand, therefore, this study aims to provide a model for predicting the water consumption via box and jenkins method. to this end, monthly data for the domestic and agricultural water consumptions of tehran provi...

This study develops water footprint scenarios for Europe for 2050, at the country level, based on projections regarding population and economic growth, production and trade patterns, consumption patterns (diets and bioenergy use) and technological development. The objective is to estimate possible future changes in the green, blue and grey water footprint (WF) of production and consumption, to ...

for about a decade the virtual water trade has been highlighted as a means of promoting water efficiency and helping to solve regional restrictions of water resources in order to provide water and food security. although these tools are not just for certain areas of the world with a specific climate, they are more important for countries which are faced with water resources restriction and cris...

Duckweed systems are a form of natural wastewater treatment method that is ideal for developing countries. They demand less in terms of financial resources for construction and maintenance, manpower sophistication, electricity requirements, and machinery. This paper looks at the duckweed technology as a new phenomenon in Zimbabwe, reviews its requirements and problems, and finally explores its ...

We explore Tinbergen’s fundamental insight that policymakers need at least as many policy instruments as targets. We extend this idea using a large natural field experiment in water resource management. We use social comparisons and loss-framed messages to help achieve two goals of our partner utility: getting consumers to purchase drought-resistant plants and reducing water use. Our results sh...
