The Barometer of Sustainability is a method of two-dimensional analysis which assesses the wellbeing in human and ecological dimensions of an equitable and systematic system, not leaving the data overlap, not masking the results and finding in a Wellbeing Index. The results showed that Ribeir^o Preto is on intermediate level in relation to sustainable development with better performance in human dimensions. The themes of Soil and Biodiversity were considered unsustainable in the analysis of findings. This reveals that the city presents a greater concern with the socio-economic issues at the expense of environmental issues.展开更多
