Impactos da irrigação por pivô central sobre a economia de Morrinhos - Goiás

Abstract

This paper aims to analyze the economic impacts that central pivot irrigation can cause to rural producers, society and the environment, discussing both the benefits and challenges associated with this practice. The analysis will be supported by a review of the existing literature and recent data on the irrigation situation in Brazil, in Goiás and based on the available data on the city of Morrinhos. The use of the central pivot irrigation technique is consolidated in Goiás and tends to expand in the coming years, with this growth being gradual and continuous, which facilitates long-term management actions. The process of agricultural expansion and crop diversification through central pivot irrigation has had a direct impact on the generation of income and wealth in the economy of the municipality of Morrinhos. As a municipality considered one of the main grain producers in the state of Goiás, the advancement and expansion of the practice of central pivot irrigation in plateau areas has been a cause for concern for the scientific community involved in socio-environmental issues, mainly due to the environmental impacts and social conflicts generated by the high demand for water resources for its supply. This is due to the significant water requirement of irrigated agriculture.
