From the Cover: Water-controlled wealth of nations

Andrea Rinaldo, Samir Suweis, Paolo d'Odorico, Amos Maritan

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 ...

Retention behaviour of natural clayey materials at different temperatures

Lyesse Laloui, Simon Salager, Marta Rizzi

The water retention capacity of geomaterials, and especially clayey soils, is sensitive to temperature changes as the physical mechanisms of retention, such as capillarity or adsorption, are affected by it. It is therefore a major issue to be able to defin ...

Evolution of the global virtual water trade network

Andrea Rinaldo

Global freshwater resources are under increasing pressure from economic development, population growth, and climate change. The international trade of water-intensive products (e.g., agricultural commodities) or virtual water trade has been suggested as a ...

Temporal dynamics of blue and green virtual water trade networks

Andrea Rinaldo

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 ...

Hydrologic Activity of Deciduous Agroforestry Tree Observed through Monitoring of Stable Isotopes in Stem Water, Solar Radiation Attenuation, and Sapflow

Marc Parlange, Natalie Claire Ceperley, Theophile Mande

The net benefit of agroforestry trees for small scale farmers in dryland agricultural systems is debatable because while they provide significant direct and indirect services, they also consume considerable amounts of scare water resources. In this study w ...

THERMOECONOMIC ANALYSIS AND OPTIMISATION OF AIR-BASED BOTTOMING CYCLES FOR WATER-FREE HYBRID SOLAR GAS-TURBINE POWER PLANTS

Raphaël Michel Adrien Marie Sandoz

Among the plethora of alternatives available, concentrated solar power (CSP) appears as one of the most favourable options. The stability and dispatchability of production achievable by the integration of storage and fuel-solar hybridisation are amidst the ...

Manganese Oxidation Induced by Water Table Fluctuations in a Sand Column

Janet Gordon Hering

On off cycles of production wells, especially in bank filtration settings, cause oscillations in the local water table, which can deliver significant amounts of dissolved oxygen (DO) to the shallow groundwater. The potential for DO introduced in this manne ...

Carbon Nanotubes With Different Orientations for Electrochemical Biodevices

Giovanni De Micheli, Sandro Carrara, Irene Taurino

Carbon nanotubes (CNTs) improve the sensitivity of electrochemical biosensors. An optimized CNT/trasducer inte- gration is required to realize accurate devices. The nanotube orientation on the sensor electrode is a key parameter. The role of the sidewalls ...

Water for food: The global virtual water trade network

Andrea Rinaldo, Samir Suweis

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 ...

Structure and Controls of the Global Virtual Water Trade Network

Andrea Rinaldo, Samir Suweis

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 ...
