In this paper we analyse the economic impact of alternative water management instruments that allow addressing the problem of non-renewable groundwater pumping in the aquifers of the Guadalentín Valley (southeast Spain). Their impact is assessed using a partial equilibrium mathematical...

Using a bio-economic model, H2OBeef, that includes traditionally considered parameters associated with running a beef feedlot but also incorporates aspects associated with water, changes that can alter water consumption and or price are examined. The results indicate that when water does not...

Agricultural production is highly dependent on inorganic substances including fertilizers. High-yielding crop varieties, such as corn, require large amounts of primary nutrients including nitrogen, phosphorus and potassium. Farmers often add a surplus of nutrients to crops to maximize yields....

This paper uses a complicated set of phase-ins and phase-outs of oxygenated motor fuel in the Northeast to determine whether E-10 ethanol-enhanced fuel contributes to acetaldehyde air pollution over the pre-ethanol methyl tertiary-buthyl ether (MTBE) fuel. Oil companies phased out MTBE because...

Este trabajo estima el valor economica del agua utilizada por los campos de gold en proyecto en la Comunidad Valenciana, Region de Murcia y Almeria. Para ello se utilizan los reultados de distintos estudios sobre el impacto economico de este deporte y se calcula el consumo medio de agua por cada...

The main objective of this study is to account for spatial preference variability in the economic valuation of water quality improvements in the river basin context. This is expected to be particularly relevant for the implementation of the European WFD, as it will involve spatially...

Este trabajo analiza el valor económico de uso del agua en la agricultura de regadío de la Cuenca del Segura y en las zonas regables que utilizan recursos procedentes del trasvase Tajo-Segura,para lo que se emplea un modelo de programación matemática no lineal que asigna los recursos...

Increased concentration of greenhouse gases in the atmosphere, especially of carbon dioxide, has led to attempts to implement carbon policies in order to limit and stabilize gases at acceptable levels. Agricultural activities increase greenhouse gases in the atmosphere, but they can also...
