Abstract

This paper presents a part of ongoing research into the resilience potential of the western coastal front of Thessaloniki, a medium sized city in northern Greece. It aims to assess whether and to what extent the western coastal front of Thessaloniki, Greece, currently a partially developed area, features elements of resilience and what opportunities can be harnessed to this end. We set out by describing the concept of ‘urban resilience’ drawing upon recently published literature. As primary principles of resilience-driven development, we identify (i) the existence of resilience-focused spatial planning attributes (redundancy, modularity, buffering, connectivity, existence of legally binding land-use or zoning plans) (ii) the presence of a highly adaptive urban spatial management mix, (iii) reflectiveness and the ability to learn from past experience and resilience challenges and (iv) civic engagement, largely facilitated by means of smart city applications. We then shift our focus to the characteristics of the study area. In order to investigate the extent to which the identified from the literature factors affecting urban resilience apply in this area, a profiling of the study area is made, followed by an in-depth analysis of whether and how the identified principles of resilience-driven development are realized through the current urban, regional, transportation and environmental planning and management frameworks applicable to the area. We close with highlighting specific aspects of resilience that call for urgent attention and by making comments and recommendations regarding policy integration needs.

Abstract

Urban sprawl processes taking place in European cities constitute an important problem opposing sustainable growth and environmental protection. This is particularly evident in the Mediterranean, where intense tourism development and coastalization continuously impose urban land pressures on agricultural areas and natural land. In the present study a set of 14 coastal medium-sized cities of Spain, Italy, Greece, Mediterranean France and Malta is used to explore recent urban sprawl trends and to analyze different typologies of urban form and structure. Based on recent data from European databases (Urban Atlas, Corine Land Cover and the Imperviousness-Soil Sealing Degree dataset), soil sealing degree profiles are estimated and the distribution of different urban land uses is analyzed for year 2006 using a set of spatial metrics. Urban growth between 1990 and 2014 is estimated based on data from the Global Human Settlement Layer (GHSL). Results reveal important differences between the cities in terms of urban form and structure. Geomorphology, different levels of population growth and tourism development, differences in the historical and socioeconomic context constitute among others, the reasons for this differentiation.

DETERMINANTS OF AFFORDABLE HOUSING ALLOCATION: COMMON PERSPECTIVES FROM LOCAL OFFICIALS

Abstract

In response to the wide social concerns of exponential price inflation and the severe demand for affordable housing over the last decade, the Chinese government has enforced a national plan to enhance the large-scale construction and provision of affordable housing, while municipal governments are responsible at the local level for implementation and allocation via various housing provision programs. In this paper we collected first-hand data from a series of personal interviews with government officials to conduct a systematic analysis of the challenges of housing allocation from the perspectives of administrators at the city level. In light of the responses from practitioners, the four main concerns giving rise to low efficiency and unfairness in housing allocation are: the faction of agencies, ineffective monitoring systems, the lack of transparency of information, and the absence of legal enforcement. Legal enforcement is the most important institutional establishment as it stipulates agency collaboration and monitoring. Transparency, which is affected by legal enforcement, also enhances cooperation among departments.
