Water shortages and climate change are worldwide issues. Reduction in water leakage in distribution networks as well as the associated energy saving and environmental impacts have recently received increased attention by scientists and water industries. Pr ...
This thesis analyses three distinct aspects of the economics of water distribution in Switzerland. Climate change and mounting pressure regarding the performance of network industries command an understanding of the drivers of cost and efficiency of water ...
Water and food are basics of human life, unfortunately climate changes and water pollution have reduced the amount of water available for human uses. In this context the study of the hydrologic cycle is becoming of growing importance in order to optimize t ...
Global food security increasingly relies on the trade of food commodities. Freshwater resources are essential to agricultural production and are thus embodied in the trade of food commodities, referred to as "virtual water trade." Agricultural production p ...
Population growth is in general constrained by food production, which in turn depends on the access to water resources. At a country level, some populations use more water than they control because of their ability to import food and the virtual water requ ...
Recurrent or ephemeral water shortages are a crucial global challenge, in particular because of their impacts on food production. The global character of this challenge is reflected in the trade among nations of virtual water, i.e. the amount of water used ...
We propose and analyze an important extension of standard cholera epidemiological models, explicitly accounting for fluctuations of water availability to the human community under study. The seasonality of water input in the reservoir drives the variation ...
We present a novel conceptual framework and methodology for studying virtual water trade. We utilize complex network theory to analyze the structure of the global virtual water trade associated with the international food trade. In the global virtual water ...
The commercially available fluorescence dye 8-hydroxypyrene-1,3,6-trisulfonate (HPTS) can be used as a selective molecular probe for the detection of caffeine in aqueous solution. ...
In the near future, Switzerland is predicted to be affected by climate change, that is bound to impact both water demand and water supply in multiple ways. While water demand by households, firms and agriculture increases, water supply decreases (ProClim a ...
