Objective: Water scarcity is a growing global problem and increasing population pressures, living standards and the growing demand for environmental quality have evoked all the governments to represent better solutions about water resources management. In addition, there are growing political ties for reducing water use in agriculture that follow enough environmental benefits and increase the w...

China's economic growth is expected to continue into the next decades, accompanied by sustained urbanization and industrialization. The associated increase in demand for land, water resources, and rich foods will deepen the challenge of sustainably feeding the population and balancing agricultural and environmental policies. We combine a hydrologic model with an economic model to project China'...

The release policy for a reservoir’s network can be designed by solving a multiobjective control problem. However, the use of resolution algorithms based on stochastic dynamic programming, with their high computational requests, imposes strong simplification in modelling the water system. In particular, downstream irrigation districts are often described as static subsystems, i.e. assuming an a...

Irrigation is well known for being the largest water user, responsible for about 70% of the total amount of fresh water withdrawals. At the same time, this irrigation contributes for about 40% of the total food production and is vital for many regions of the world such as Western USA, Australia, Southern Europe, and many countries in Asia and Africa. Recent FAO figures indicate that, by the yea...

The interest in techniques to improve water use efficiency (WUE) such as controlled deficit irrigation is rising due to the emergence of strong competition for fresh water in order to comply with the increased demand for food worldwide. Additionally, the use of crop models in conjunction with complex decision support systems becomes more and more widespread making it essential to reliably predi...

water is the most limiting factor in irrigated agriculture, mainly in mediterranean environments, as in the case of southwest spain. in this area, almond is one of the most valuable crops due to its high drought tolerance. this work examines the crop coefficients (kc) based on four drainage lysimeters installed in an experimental young almond orchard. complementary, two deficit-irrigation treat...

Evapotranspiration (ETc) is the mean for exploiting irrigation water and constitutes a major component of the hydrological cycle (Telis et al., 2007; Papadavid, 2011). The ETc is a basic and crucial parameter for climate studies, weather forecasts and weather modeling, hydro‐ logical surveys, ecological monitoring and water resource management (Hoedjes et al., 2008). In the past decades, the es...
