    Effect of Urbanization on Groundwater Resources of Izmir City
    (İZSU, 2017) Baba, Alper; Yazdani, Hamidreza
    İzmir is the third largest city in Turkey. Fifty­six percent of the drinking water of İzmir city is provided from groundwater resources. Halkapınar (located on Bornova Plain) is one of the important groundwater resources areas. This region is providing 16 % of İzmir drinking resources. The water withdraws from the Halkapınar wells is about 30 million m3 in recent years. The groundwater levels of Bornova plain are range from 1 m to 10m. This plain had been used as agricultural lands until the 1950s, while today they have been opened for settlement. In 1965 Bornova accommodated half of its population in rural areas after receiving so much immigration. It was inevitable to open the city­centre to housing and to consider the surrounding village areas as urban areas. By the year 2000, the rural population had already been melted into the urban population. The agricultural areas in rural parts of the country will have completely disappeared in 50 years' time. Much of the surface of the plain is rendered impermeable by buildings, roads and surface coverings. Because of this covering, groundwater recharge is reduced and increases and accelerates runoff the plain. The groundwater recharge from precipitation was about 27 % in 1925, but this amount dropped to 13% in 2012. Groundwater recharge from precipitation will be 1% in 2030. Hydrodynamic of plain is change because of excessive urbanization. Groundwater level of the plain still high because tall building makes a barrier for groundwater recharge points.

    Spatial Transformations in Istanbul Cbd: the Role of Ict?
    (Information Science Reference, 2008) Geçer Sargın, Feral; Avar, Adile; Velibeyoğlu, Koray; Saygın, Mustafa Ömür
    Now with the intensive use of information and communication technologies, many cities around the world are competing to become a global city. Istanbul is enumerated within the first 50 cities in the globalization process, other than the triad of New York, London, and Tokyo. This chapter explores urban space transformation of Maslak, the contemporary central business district of Istanbul, with respect to information and communication technologies, by using deconcentration and economic restructuring approaches of urban theory. Compared to other global cities, Istanbul has distinctive characteristics, since it has been passing through a unique transformation process. More specifically, its economic, political, and social characteristics distinguish Istanbul from other cities within the same category (Gamma) of world cities. This study has revealed that transformations in Istanbul were not primarily driven by information and communication technologies. In contrast information and communication technology's role in the transformation of the Istanbul central business district is only a contributing factor.

    Understanding the Supply Side: Ict Experience of Marmara Region, Turkey
    (Information Science Reference, 2008) Velibeyoğlu, Koray; Yiğitcanlar, Tan
    Marmara region's local governments in Turkey are setting the benchmark for the country in the implementation of spatial information systems and e-governance. The chapter aims to shed light on organizational realities of recent practices of information systems and technologies based on the evidences from selected local government organizations in the Marmara region. This chapter scrutinizes these practices and discusses the pivotal relationship between the information and communication technologies and its local organizational context within the region. The chapter also exemplifies challenges and opportunities of the Marmara as an emerging information and communication technology-supported region by illustrating the specific information and communication technology supply instruments. The chapter reveals that the particular success in supply side does not guarantee the sustainable information and communication technology implementation. There are other concerns including demand side that are strongly linked to a realistic understanding of end user demand, the institutional capacity of respected organizations, public-private partnership, and the joined-up policy efforts at both national and local levels.

    Online Participatory Decision Support Tools for Knowledge-Based Urban Development
    (Information Science Reference, 2008) Yiğitcanlar, Tan; Saygın, Mustafa Ömür; Han, Jung Hoon
    Particularly in the last decade, there have been a number of efforts to develop and then integrate planning support systems into existing geographic information systems. This integration brought a new technology called WebGIS, which enables geographic information systems functionalities through the Internet for decision support. No doubt there is a growing demand as more and more individuals want to use online government services to express their views and most importantly to take part in decisionmaking processes interactively. At this point, WebGIS offers a challenging opportunity for online participatory planning since the public could easily access alternative plans and the existing information in geographic information systems databases. This technology enables individuals to be able to take part in plan-making processes and contribute. This chapter explores how these new technological advances could achieve truly transparent plan-making process based on online participatory planning support tools that knowledge-based urban development could benefit from.

    Queensland's Smart State Initiative: a Successful Knowledge Based Urban Development Strategy?
    (Information Science Reference, 2008) Yiğitcanlar, Tan; Velibeyoğlu, Koray
    During the last two decades, knowledge-based development has become an important mechanism for knowledge economies. In a knowledge economy, information and communication technology is extensively seen as a potentially beneficial set of instruments, which may improve the welfare and competitiveness of nations and cities. At present, both public and private actors aim to exploit the expected benefits of information and communication technology developments. These technologies offer unprecedented promise for social and economic development on all global, national, regional, urban, and local levels. Therefore, this chapter seeks to investigate the potential of information and communication technology policy at both regional and urban levels, and, in particular, to shed light on various factors that influence urban information technology policies in the public domain. The chapter sets out to explain the knowledge-based urban development processes and challenges and opportunities in information acceptance and use in urban policy-making in Queensland, Australia. This chapter draws on providing a clear understanding on policy frameworks and relevant technology applications of the Queensland Smart State experience.
