ABSTRACT. 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 weather, location, productmix and production technology. Implications of these results for policies designed to manage agriculture and water use are discussed. |

The carbon of microbial biomass is a good indicator to soil changes. This work had the objective of evaluating the effect of organic residue burning on soil microbial biomass carbon content (C-bio) in area cultivated with corn. The evaluations were conducted 90 and 130 days after the emergency (dae). For 90 dae, the burning of residues increased the C-bio, while in the evaluation of 130 dae the burning of residues had no effect. Among the evaluations made to the 90 and 130 dae, the burning of residues reduced the C-bio. |
