This paper presents a literature review on the possibility of a city becoming environmentally sustainable. As a case study, a diachronic analysis of the landscape (landscape evolution) of the Cachoeira neighbourhood (Curitiba-PR) was carried out, since the 1950s, using the concept of hemerobia, to verify if the transformations that occurred in the neighbourhood took it to a state of environmental sustainability. The concept of hemerobia adopted in the research was that of energy and technological dependence needed to maintain the landscape. The application of the hemeroby concept in the Cachoeira neighbourhood was carried out based on the visual interpretation of aerial photographs and Google Earth Pro satellite images from the years 1952, 1972, 1990, 2003 and 2018. Mosaics with the images and cartograms of hemerobia were elaborated at a scale of 1:7,000, and the processing of the cartographic material was carried out with ArcGIS® 10.3 software. Three classes of hemeroby were adopted: low (predominance of tree vegetation), medium (herbaceous/shrub vegetation, exposed soil, agricultural crops, pastures, and/or evidence of buildings), and high (predominance of built-up/impermeable areas). In sixty years, the agropastoral landscapes of the neighbourhood were replaced by landscapes with buildings and waterproofed surfaces, resulting from the legal process of urbanization, associated with irregular occupations that destroyed springs and water bodies. Some fragments of araucaria forest survived and reached advanced stages of ecological succession. After six decades, the results indicated that buildings (high hemeroby) occupy 37.22% of the total neighbourhood area, 18.09% are occupied by herbaceous/shrub vegetation and exposed soil (medium hemeroby), and 44.69% are occupied by tree vegetation (low hemeroby). These values point to a good state of conservation of the nature found in the neighborhood, and indicates that the forest fragments would be in a state of environmental sustainability, but the rest of the neighborhood has not evolved towards environmental sustainability.
