Urban Equity as a Challenge for the Southern Europe Historic Cities: Sustainability-Urban Morphology Interrelation through GIS Tools

Abstract

At a local level, public authorities’ decision making has a significant influence on the development, structure and spatial configuration of the city. For this reason, it is considered essential to combine political positions with urban sustainability criteria, particularly in cities that have been declared World Heritage Sites by UNESCO. The objective of this research is based on establishing an analysis of the formal relationship between sustainability and spatial morphology in the city of Cáceres, taking into account the urban planning conditions in two areas of study: The Historic Centre (PCH) and the city as a whole. The methodology applies a series of urban indicators from four different fields, namely land use, public space, mobility, and urban complexity, with later GIS analysis using a 1 ha grid pattern. Results show correlation exists between historical zones and the degree of some indicators like density, compactness, acoustic comfort or street proportion, and streetscape, while others seem to depend on further conditions. The case of Caceres provides new findings in the Human Heritage Cities research field for Spain and Southern Europe. Grid pattern analysis has shown to be useful to most of the indicators, although some would require different approaches in the future. The authors consider the use of geoinformation tools as an opportunity for mid-sized and similar historical cities’ policymakers, with our ultimate goal being achieving further equity in urban quality conditions. In conclusion, it is considered that there is a knowledge gap regarding the existence of multiple open data sources belonging to different public administrations and the transformation of these data into useful parameters for their practical application at the citizen level.

Characterisation of Morphological Patterns for Land Surface Temperature Distribution in Urban Environments: An Approach to Identify Priority Areas

“…This approach yielded 219 polygons, each covering an equal surface area of 1 hectare. The selection of this grid and its dimensions were determined to be suitable for this study following a thorough review of the relevant literature [14,[30][31][32]. The grid is widely acknowledged as the second most employed unit in urban studies and is comprehensively defined in the work of Liu et al [33].…”

“…Partnerships: partnerships between countries to encourage development Existing articles on equity and sustainability range in various aims, including emphasizing the importance of sustainability in future projects [11], identifying challenges and evaluating current ways equity and sustainability are achieved [8,[17][18][19], and recommending strategies for incorporating equity and sustainability [7,20]. This area may also range in a variety of fields across the health and environment intersection [9,20,21].…”
