“…For example, Poelmans et al [56] is potentially relevant to resilience if maintaining adequate water supply falls under its umbrella, but the authors are vague as to how their work is connected to shortages and planning for sustainable water supply. Similarly, Domene and Saurí [47] is relevant if we expand the understanding of the resilience theme to include water availability more generally and the same is true for Zasada et al [31] and Küçükmehmetoğlu and Geymen [34].…”

“…Several of the studies we analysed are more general and consider watershed health [43] or the urban water balance [48,56], while others focus specifically on stormwater runoff [45,55,61], potable water supply [34,57], flooding [32], or household consumption patterns [50].…”

“…The loss of wetlands and the ecological services they provide is a prominent theme in three of the six publications considered [19,41], while water supply [34], and general watershed health [36] are also represented. China and India again dominate, with five of the six articles focusing on study areas from these countries.…”

“…The lone exception focuses on Istanbul, Turkey which ranks as one of the densest cities in the world and whose geography and size make water accessibility particularly challenging. Küçükmehmetoğlu and Geymen [34] document the water resource basins available to meet Istanbul's demand, noting that with an average population growth rate of 4.5% and intense growth pressure to expand outward from the crowded core, water resources are severely constrained. Using satellite imagery and GIS to document and monitor land use changes, the authors found that leap-frog, low-density development has increased in recent decades due in large part to capital improvement projects designed to improve accessibility to the city core.…”

“…A lack of -systematic regional land-use planning‖ coupled with -the fragmented local government structure within each metropolitan area‖ has fuelled suburban sprawl on the periphery of Indian cities ( [14], p. 404). Küçükmehmetoğlu and Geymen [34] contend that a lack of planning and enforcement of existing regulations designed to protect water supply watersheds has led to sprawling development within the Istanbul metropolitan area. In China, a lack of planning is not generally considered to be an underlying driver of urban sprawl, but rather the result of the inability of central planners to consider the full range of impacts associated with development decisions [14,37].…”

The Environmental Impacts of Sprawl: Emergent Themes from the Past Decade of Planning Research

Abstract:This article reviews studies published in English language planning journals since 2001 that focus on the environmental impacts of sprawl. We organise our analysis of the reviewed literature around: (1) the conceptualisation or measurement of sprawl; (2) a comparison of research methods employed and findings with respect to four categories of environmental impacts-air, energy, land, and water; and (3) an exploration of emergent and cross-cutting themes. We hypothesise that the trend towards breaking down silos observable in other areas of planning scholarship is also reflected in the recent sprawl literature and structure our review to test this proposition. International in scope, our work demonstrates how focusing on outcomes can facilitate balanced comparisons across geographic contexts with varying rates of urbanisation and affluence. We find that the sprawl research published in planning journals over the past decade frequently engages with broader themes of resilience and justice, increasingly considers multiple environmental outcomes, and suggests a convergence in the way sprawl is studied that transcends national boundaries as well as the developing-developed country dichotomy.

IMPACTS OF BOSPORUS BRIDGES oN THE ISTANBUL METROPOLITAN SETTLEMENT AREAS

Istanbul, one of the largest metropolitan cities in the world, experienced rapid industrialization and urbanization in the second-half of the 20th century. The City grew at an average annual growth rate of 4.5 per cent between 1950 and 2000. Growth of settlements and the transportation system have damaged the natural environment. Istanbul is located on both sides of the Bosporus Strait that divides Europe from Asia. Recently an alternative to the planned third bridge for the Istanbul metropolitan area has been selected. The transportation infrastructure which has been constructed has drastically changed the land use profile and caused negative impacts on the environment. The proposed third bridge route threatens agricultural areas, forests, waterbodies and water collection areas that form the open-space systems of Istanbul.The aim of this study was to analyse the effects of existing Bosporus bridges on the spatial development and the natural resources of the metropolitan area of Istanbul. With the new transportation axis focused on the bridge route, the potential impacts on vital open spaces such as the northern forest regions, the existing agricultural lands and the waterbodies and catchments are evaluated. These changes are explored using a geographical information system and five sets of Landsat satellite images from 1975, 1990, 1995, 2000 and 2005. This should provide a better understanding of the main reasons for the effects and will support city administrators planning similar projects.
