“…GIS, another popular tool, assigns spatial coordinates to data that can be mapped, and it can map both spatial and nonspatial information (5,11,55). A number of GIS software utilities are available online, such as ArcGIS (54), and limited versions are sometimes made available for free.…”

The research community has shown increasing interest in developing and using metrics to determine the relationships between urban living and health. In particular, we have seen a recent exponential increase in efforts aiming to investigate and apply metrics for urban health, especially the health impacts of the social and built environments as well as air pollution. A greater recognition of the need to investigate the impacts and trends of health inequities is also evident through more recent literature. Data availability and accuracy have improved through new affordable technologies for mapping, geographic information systems (GIS), and remote sensing. However, less

Topics of sustainable urban development and environmental sustainability are worldwide considered as fundamental for every strategy of urban transformation, renewal and regeneration. In particular, urban regenerations are urban re-development programs involving the rebirth or renewal of selected urban areas or district that have faced periods of decline due to compounding and intersecting pressures. The programs cover many aspects of the area to be re-generated such as physical, social and environmental contexts. Re-use of already built up areas and buildings, reduction of the demand for new soils to be developed, increasing of appealing of dense city areas, increasing of social and spatial resilience are among the positive consequences of these programs. However, in the current debate about urban regeneration, few studies have evaluated the real environmental outcomes and effectiveness of regeneration programs in terms of physical variables such as new provided greenspaces, accessibility to public transportation, climate change or seismic risk reduction. This paper proposes a method to quantify the real outcomes and effectiveness of urban regeneration programs with reference to the above mentioned variables. As a real experience of urban planning, the new Local Spatial Plan for the Municipality of Catania, a medium sized city in Southern Italy, is presented. The city is characterised by a high density urban fabric, a general lack of urban greenspaces and high levels of traffic congestion due to a massive use of private transportation. The urban fabric is also very vulnerable to seismic and climate change risks. Among the transformation tools, the new Local spatial plan proposes regeneration actions aimed at the complete regeneration of old and dilapidated areas, not classified as historical heritage and heavily vulnerable to seismic risk. These actions include the complete demolition and reconstruction of these areas within clearly defined boundaries, contributing to minimise soil consumption, maintaining as open public spaces the majority of existing non urbanised areas within the densely built-up settlement. The program of regeneration can dramatically contributes to the reduction of seismic and climate change risk and achieve a general requalification of the urban environment. Starting from this planning experience, this paper focus on the evaluation of the regenerations programs included in the Local Spatial Plan. Regeneration Areas (RAs) have been identified by the municipality as characterized by high level of seismic vulnerability, urban degradation, lack of public services and urban environment quality. For the chosen areas, this study proposes the evaluation of the transformations potentially occurring in the urban context by the proposed regeneration program. The following aspects are evaluated: -reduction of risks (in terms of exposition and vulnerability to seismic and climate change related risks)

“…In recent years, the modelling of accessibility has substantially evolved thanks to enhanced GIS features, particularly the development of GIS modules, such as the ArcGIS Network Analyst Tool, and personal computers' computational capabilities. There are two common approaches, including the Euclidean Buffer (simple radius methods) and Network Analysis (Nicholls, 2001, Oh & Jeong, 2007, Moseley et al, 2013, La Rosa, 2014.…”

ABSTRACT:Accessibility analysis of urban emergency shelters can help support urban disaster prevention planning. Pre-disaster emergency evacuation zoning has become a significant topic on disaster prevention and mitigation research. In this study, we assessed the level of serviceability of urban emergency shelters within maximum capacity, usability, sufficiency and a certain walking time limit by employing spatial analysis techniques of GIS-Network Analyst. The methodology included the following aspects: the distribution analysis of emergency evacuation demands, the calculation of shelter space accessibility and the optimization of evacuation destinations. This methodology was applied to Adana, a city in Turkey, which is located within the Alpine-Himalayan orogenic system, the second major earthquake belt after the Pacific-Belt. It was found that the proposed methodology could be useful in aiding to understand the spatial distribution of urban emergency shelters more accurately and establish effective future urban disaster prevention planning. Additionally, this research provided a feasible way for supporting emergency management in terms of shelter construction, pre-disaster evacuation drills and rescue operations.
