This paper proposes a new Economic Drought Management Index (EDMI) that could assist water managers to inter-temporally manage water reservoirs. The index's main appeal is that it can be easily interpreted and that it encompasses in a single number hydrological processes, structural constraints,...

Reservoir management and intertemporal water allocation are critical issues in semiarid regions where agriculture has to confront highly variable rainfall patterns. In this paper, we derive and propose an economic drought management index (EDMI) to evaluate water institutions' performance to...

The report provides a starting point for a debate on the use of irrigation subsidies in Spain, quantified using the GSI's Method for quantifying irrigation subsidies. The report found subsidies to irrigated agriculture are in the range of €900 to €1120 million per year. More than half of...

Water availability in semiarid regions commonly exhibits patterns of extreme variability. Even in basins with large infrastructure development, some users are subject to low levels of water reliability, incurring economic losses during periods of scarcity. More flexible instruments, such as...

The methodology used for Economic Valuation of the Externalities generated by the Watershead Restoration and Erosion Control Projects in the Hydrographic Basins of the Mediterranean Slope, is based on the Replacement Cost Method. Environmental Economics, however, today offer us other...

Espana es el tercer productor y el primer exportador mundial de freson. Toda esta produccion esta mayoritariamente concentrada en una zona, convirtiendo a Huelva en la mas importante regon exportadora de freson del mundo. En base de las investigaciones realizadas, los instrumentos de gestion de...

RESUMEN: La evidencia disponible sobre los efectos externos de los mercados de agua actualmente en funcionamiento es contradictoria. Algunos trabajos demuestran que el intercambio de agua reduce la contaminación derivada de los sistemas productivos del regadío, mientras que otros concluyen lo...

En este estudio se aplica la teoría de opciones reales para valorar, desde la óptica del productor, un seguro de rentas contra la caída de los precios de patata en origen. Este seguro fue ofrecido en cinco provincias españolas en 2003 y 2004. Se trata de un seguro índice que no toma como...
