Water-Energy-Food nexus status in Brazil

Fernando Caixeta

Abstract


This article investigates the relationship between the water-energy-food (WEF) nexus in Brazil in an exploratory and statistical study over the period from 2000 to 2013. For that purpose, the explanatory variables considered were the following: Access to improved water; Access to electricity and Average protein supply. Furthermore, it was introduced some brief facts about WEF nexus security in Brazil. With such explanatory variables, it was performed descriptive statistics, ensuring the assumption of data normality approach, and consequently calculating the descriptive statistics and correlation. The results of correlation showed that the quantitative relation between the three factors was extremely strong. These data allowed to understand the relation between these indicators and its status as a nexus in Brazil. Therefore, it is concluded that pursuing an active policy to manage demand in WEF nexus could lead sustainability processes.
