| This paper proposes an 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 encompasses in a single number hydrological processes, structural constraints, water institutions' rules and the economic benefits of the customers served from the supply system. An empirical application of EDMIs is performed for two irrigation districts in Andalusia (Southern Spain), that are managed under different institutional arrangements. Results for one district show that the region's vulnerability to drought could be reduced following the interpretation of the EDMIs. For the other district, the index shows that water stocks are managed... |

| RESUMEN: En este artículo se aborda la problemática que plantea la recuperación del acuífero Mancha Occidental en el que existe una importante externalidad ambiental que se deriva de la relación entre las reservas de agua existentes en el acuífero y los humedales Tablas de Daimiel. Para ello, se desarrollan varios modelos de programación matemática que permiten evaluar distintos instrumentos de gestión para guiar la recuperación del acuífero a un estado sostenible. Los resultados obtenidos permiten al menos cuestionar la extendida regla de Gisser-Sánchez y revelan que las ganancias derivadas de la gestión óptima pueden ser significativas. En segundo lugar, las cuotas constantes por explotación se revelan como el instrumento menos eficiente tanto desde la... |
