An Economic Drought Management Index to Evaluate Water Institutions' Performance AgEcon
Iglesias, Eva; Garrido, Alberto; Gomez, Almudena.
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...

Analysing options for the Red Gum Forests along the Murray River AgEcon
Bennett, Jeffrey W.; Dumsday, Robert G.; Gillespie, Robert.
The Victorian Environmental Assessment Council is conducting an investigation into the management of the public land River Red Gum Forests of the Murray River Valley in Victoria. In this paper the authors apply the results of an earlier Choice Modelling exercise commissioned by VEAC to estimate the non-use values of the forests. A Benefit Cost Analysis of VEAC's draft recommendations included assessment of the market and non market values associated with different River Red Gum forest management strategies. It is concluded that the use of water for environmental flows is competitive with its use for irrigation. Other economic values associated with timber harvesting, grazing and duck hunting are small in comparison with the water values.

Sugarcane Water Productivity Assessments in the São Paulo state, Brazil. Repositório Alice
TEIXEIRA, A. H. de C.; LEIVAS, J. F.; RONQUIM, C. C.; VICTORIA, D. de C..
São Paulo state, Brazil, has been highlighted by the sugarcane crop expansion. The actual scenario of climate and land use changes, bring attention for the large-scale water productivity (WP) analyses. MODIS images were used together with gridded weather data for these analyses. A generalized sugarcane growing cycle inside a crop land mask, from September 2011 to October 2012, was considered in the main growing regions of the state. Actual evapotranspiration (ET) is quantified by the SAFER (Simple Algorithm for Evapotranspiration Retrieving) algorithm, the biomass production (BIO) by the RUE (Radiation Use Efficiency) Monteith?s model and WP is considered as the ratio of BIO to ET. During the four generalized sugarcane crop phases, the mean ET values...

THE SOCIO-ECONOMIC CONSEQUENCES OF THE IMPACT OF CLIMATE CHANGE ON WATER RESOURCES IN SOUTH AFRICA AgEcon
Juana, James S.; Strzepek, Kenneth M.; Kirsten, Johann F..
Most of the climate change models for South Africa predict a reduction in freshwater availability by 2050, which implies that water availability for sectoral production activities is expected to decline. This decline has an impact on sectoral output, value added and households’ welfare. Using a computable general equilibrium approach, this study investigates the possible impact of global change on households’ welfare. The simulation results show that water scarcity due to global change can potentially lead to a general deterioration in households’ welfare. The poor households, whose incomes are adversely impacted, are the most vulnerable to the consequences of the impact of global change on water resources in South Africa. This vulnerability can only be...
