The paper examines different literature or theoretical streams that contribute to the debate related to the notion of livable cities. It juxtaposes academic constructs from architecture and urban planning fields with the popular culture and web indices that rank cities according to their living standards, services, and international appeal. The study offers a comparative analytical assessment of these diverse approaches and lays out a nuanced understanding of urban livability that draws on the richness and diversity embedded in design, planning, and current ranking tools. The paper ultimately aims to shed light on the configurations, conditions, and processes that may enhance the livability of various urban settings. It integrates such disparate views into an interdisciplinary perspective of urban livability. While the bulk of this paper analyses relates to North American, European, and Australian cities, the concepts discussed pertain to urban livability on a Rlobal scale.展开更多

Urbanity Index and Landscape Vulnerability Indicator have been proposed to improve the impact interpretability of land use changes on sub-basin sustainability for local scenarios of biodiversity conservation. A time series of LandSat 5 Thematic Mapper remote sensing data from São Carlos municipality, Southeastern Brazil, for the years 1989, 2004 and 2014 revealed that land use changes in the sub-basins do not take place in a progressive and gradual way. Over the 25-year period, the main trends showed the loss and increase of forest cover so that it has remained quantitatively similar over time due to reduced agricultural land use. The aggregation of both indicators enabled the identification of greater naturalness and lower vulnerability, as well as lower naturalness and higher vulnerability under local sub-basin conditions, pointing the need for different strategies for sub-basin biodiversity conservation and sustainability. These preliminary scenarios provide a way to communicate problems of environmental sustainability at different landscape scales to the scientific community as well as to planners, policy makers and the broader public.展开更多
