Waterlogging and salinisation have contributed to the demise of ancient civilisations and continue to threaten the sustainability of irrigated agriculture today. This paper evaluates the adoption of higher efficiency irrigation systems as an alternative for reducing the impact of waterlogging...

We use the new version of the GTAP-W model to analyze the economy-wide impacts of enhanced irrigation efficiency. The new production structure of the model, which introduces a differentiation between rainfed and irrigated crops, allows a better understanding of the use of water resources in...

Many conflicts currently take place around the world due to disputes over water use. In many major river basins of the world, water is increasingly scarce. In Brazil, some regions face problems of water deficiency, such as the Northeastern semi-arid region and some metropolitan areas. The aim of...

"The concept of resilience is widely promoted as a promising notion to guide new approaches to ecosystem and resource management that try to enhance a system's capacity to cope with change. A variety of mechanisms of resilience specific for different systems have been proposed. In the context of...

Water claims in many of the world’s arid basins exceed reliable supplies. Water demands for irrigation, urban use, the environment, and energy continue to grow, while supplies remain constrained by unsustainable use, drought and impacts of climate change. For example, policymakers in North...

In this paper, a new methodology is proposed for simultaneous allocation of water and waste load in river basins. A nonlinear interval number optimization model is used to incorporate the uncertainties of model inputs and parameters. In this methodology, the bounds of the uncertain inputs are...

Pattern formation and self-organization are phenomena that occur across the board, in animate and inanimate systems. In this paper, we rely on the constructal law to explain the generation of patterns (shapes, structures) in aggregates of organisms–pedestrian crowds and stony corals. In...
