Spatial Patterns of Land Take in a Mediterranean City: An Assessment of the SDG Indicator 11.3.1 in the Peri-Urban Area of Thessaloniki

Abstract

Urban sprawl, characterized by continuous or discontinuous spatial patterns of artificial surface expansion, has been a common trend in most cities, even in those with longstanding compact features, such as cities in the northern Mediterranean region. This paper assesses the land take patterns in the peri-urban area of a typical compact city that experienced significant sprawl trends after the mid-1990s, which are closely linked to the specificities of planning regulations regarding the development in peri-urban settlements as well as outside planned areas. Using the rapidly suburbanized southern peri-urban area of Thessaloniki, Greece, as a case study, the paper analyzes the factors influencing the land cover change in the middle-class-led peri-urbanization during the period 2000–2018 and provides an estimate of the SDG indicator 11.3.1 “ratio of land consumption rate to population growth rate”, a suitable indicator for monitoring spatial changes. The main conclusions of the study indicate that, during the period examined, the peri-urban zone investigated in the case study exhibited a higher rate of population growth compared to that of artificial surfaces, with the latter showing a higher change during 2006–2012. However, the spatial pattern of urban expansion displays a fragmented yet linear form, creating fragmented enclaves of agricultural land.
