A spatially distributed hydroeconomic model to assess the effects of drought on land use, farm profits, and agricultural employment. Repositório Alice
MANETA, M. P.; TORRES, M. O.; WALLENDER, W. W.; VOSTI, S.; HOWITT, R.; RODRIGUES, L. N.; BASSOI, L. H.; PANDAY. S..
In this paper a high-resolution linked hydroeconomic model is demonstrated for drought conditions in a Brazilian river basin. The economic model of agriculture includes 13 decision variables that can be optimized to maximize farmers' yearly net revenues. The economic model uses a multi-input multioutput nonlinear constant elasticity of substitution (CES) production function simulating agricultural production. The hydrologic component is a detailed physics-based three-dimensional hydrodynamic model that simulates changes in the hydrologic system derived from agricultural activity while in turn providing biophysical constraints to the economic system. The linked models capture the effects of the interactions between the hydrologic and the economic systems at...

Economic impacts of regional water scarcity in the São Francisco River Basin, Brazil: an application of a linked hydro-economic model. Repositório Alice
TORRES, M. de O.; MANETA, M.; HOWITT, R.; VOSTI, S, A.; WALLENDER, W. W.; BASSOI, L. H.; RODRIGUES, L. N..
This paper presents a linked hydro-economic model and uses it to examine the regional effects of water use regulations and product price changes on the agriculture of the São Francisco River Basin, Brazil. The effects of weather on surface water availability are explicitly addressed using the hydrological model MIKE-Basin. Farmers? adjustments to changes in precipitation, surface water availability, and other factors are quantified using an economic model based on non-linear programming techniques. The models are externally linked. Results show that regional impacts, at the sub-basin level, vary depending on the location of each sub-basin relative to river flows. The effects of water use regulations and of exogenous price shocks on agriculture depend on...

Water demand and flows in the São Francisco River Basin (Brazil) with increased irrigation. Repositório Alice
MANETA, M. P.; TORRES, M.; WALLENDER, W. W.; VOSTI, S.; KIRBY, M.; BASSOI, L. H.; RODRIGUES, L. N..
Most activities that support economic growth in the São Francisco Riber Basin (Brazil) need water. Allocation of the water resources to each competing use needs quantification in order to develop an integrated water management plan. Irrigation agriculture is the largest water consuming activity in the basin. It has produced large economic and social advancements in the region and has potential for further development. The local development agency in the São Francisco River has projected an increase of more than 500,000ha in irrigation developments distributed within the basin. Water requirements of the projected irrigation expansions and their effects on river flow were quantified. A semi-distributed model was constructed to simulate the water balance in...
