Water footprint of sugarcane production from 2010 to 2020 in Paraná state, Brazil

Abstract

The objective of this work was to estimate green, blue, and gray water footprints of sugarcane in the main producing mesoregions of Paraná state, from 2010 to 2020. The methodology used was proposed by Hoekstra et al. (2011), with necessary adaptations for the local reality. The mesoregion Noroeste Paranaense showed the highest values for green footprint (179.05 m³ Mg-1, in 2010, and 200.26 m³ Mg-1, in 2020). Norte Central e Noroeste Paranaense showed the highest average values for blue footprint (47,43 e 46,66 m³ Mg-1, respectively). Norte Paranaense also showed the highest gray water footprint, with 12.33 m³ Mg-1, in 2010, and 13.79 m³ Mg-1, in 2020. In the period, Noroeste Paranaense showed the highest average water footprint (249.37 m³ Mg-1), and Norte Pioneiro Paranaense showed the smallest average footprint (179.35 m³ Mg-1). The average total water footprint of sugarcane production in the mesoregions of Paraná was 206.63 m³ Mg-1.
