Avaliação da demanda hídrica por pivôs centrais e agroindústrias na Alta Bacia do Ribeirão Santo Inácio – Orizona/GO
2019
The agricultural activity is mainly responsible for water consumption use followed by industrial activity. Agro-business grows as the demand for food in the world increases. This reality is in the upper Ribeirao Santo Inacio Basin, a city named Orizona (GO), where there is a mutual dependence between irrigated agricultural activity and industrial activity. The thematic maps of this study help to understand the micro basin dynamics showing physical environment characteristics such as latosols predominance and relief low slope near the watercourses, which provides heavy agricultural activity irrigated by central pivot. The total water projection captured by central pivots was performed from the precipitation subtraction calculation and the planted crop evapotranspiration multiplied by the area size of ??each central pivot. It is concluded that in drought month’s period the water deficit reaches 1,092 cubic meters per hour, increasing the water consumption of agro industries that capture water downstream from Ribeirao Santo Inacio.
