Atualização dos sistemas de irrigação por pivô central instalados nos municípios de Paraúna e Palmeiras de Goiás

Resumo

Among irrigation systems, the central pivot was the one that grew the most in the country in
recent years, particularly in the State of Goiás, the area irrigated by central pivots increased from 1180
million in 2000 to 2120 million m² in 2010 and the number of equipment, went from 1,532 to 2,895. The
objective of this work was to update the irrigated area by central pivot, as well as the number of equipment
installed in the municipalities of Paraúna and Palmeiras de Goiás - GO, using remote sensing techniques.
The quantification of the central pivots in the municipalities of Paraúna and Palmeiras de Goiás were
carried out based on satellite images Resource 2, selected from May to August 2016. The areas with a
pivot irrigation system were identified considering circular features and In the scene and the presence of
vegetation with energy reflectance in the range corresponding to green. It was observed that in the
municipality of Palmeiras de Goiás it registered 74 pivots and Paraúna 132 pivots, occurring in both
municipalities an increase of 32 and 31%, respectively, in relation to 2010. Regarding the irrigated area,
Palmeiras de Goiás showed an increase Of 547.2 ha and Paraúna of 1251.6 ha between 2010 and 2016.
It is concluded with this work that in the municipalities of Palmeiras de Goiás and Paraúna there was a
significant increase in the area irrigated by central pivot between the years of 2010 and 2016, confirming
the region as another Brazilian irrigated agricultural pole.
