The Impact of Urban Development on Natural Lakes
Mey Chakriya(마이 짝리야),Hwang Jeewook(황지욱) 한국지역개발학회 2016 한국지역개발학회 학술대회 Vol.2016 No.11
Urban growth is a worldwide phenomenon and the rate of urbanization is very rapid in developing countries like Cambodia. It is mainly driven by unorganized expansion increased by immigration and population growth. The accelerated development in the city has made the inner city lakes, wetlands, streams and ponds filled with earth to create developable land. The impact of urban development surrounded with naturally inhabited areas in Phnom Penh has been so pervasive that the lakes are confronted with environmental disturbances. High levels of disturbance to the urban lakes in the past and recent years, such as lake infilling, land use chance, shoreline encroachment, and garbage dump, have caused urban lakes loss and floods in the city. The Boeung Kak Lake is located at the centre of urban Phnom Penh was the largest urban wet land in Cambodia. It’s a 90 hectare lake located within the Doun Penh district in the north of Phnom Penh city. A private developer, Shukaku Inc, has taken a lease of an area of 133 hectare, including the lake, from the Municipality of Phnom Penh and planned to fill and develop the area. This area is home to approximate 30,000 people living and working there. During 1980s, the lake had been a rich source of aquatic and plant life. A bustling Tourism industry been had developed around the lake encouraging the establishment of guesthouses, cafes and tour operators along the lake shore to attract the patronage of both local and international visitors(1). The lake is closed lake system, and it means that the catchment is not much larger than the lake itself. Rainfall onto the lake itself is stored within the lake until it evaporates or infiltrates. The volume of this direct rainfall on the lake was estimated during a storm event in April 2008 as 360,000m3. This event was not noted as particularly large by residents of the lake. Following filling and development of the Boeung Kak area, rainfall on the development is expected to be diverted to neighboring areas downstream to the north. While the lake is a closed system with little catchment contribution beyond the lake itself, the proposed development area is large enough to generate large volumes of runoff. This runoff has potential to cause significant impacts on property and hazard to the life downstream. The aim of this study is to investigate the land filling of a natural lake (Boeung kak), how the land filling causes extensive flooding in surrounding areas during the rainfall and thereby studying the social/ economical impacts on the livelihood of the lake’s neighborhood people through a process of data collections, technical visualization using satellite timeline images. The result of this study show that the developmental land filling of natural lakes and other water resources have so many adverse effects on economic and social aspects of a city resulting deaths of thousands and un-repairable damages to millions of dollars worth of households and education health care and infrastructure.

Recently lots of municipalities apply for the endowment & concession project through the participation of private sectors as instrument of local development and refurbishing project. This endowment & concession project is an instrument for efficient land use and management reducing the financial burden of municipalities. In this study 3 development projects are surveyed: a concession project of Incheon university & urban development of Dohwa district, the one of correctional institution of Youngdeungpo, and the one of Jeonju 35 division. The characteristics of the endowment & concession project are summarized as follows: firstly a plan and development can be simultaneously accomplished over 2 sites. Secondly the planers and developers can secure a planning period sufficiently for the development of concession site. Above all the financing of private sectors allows fund making simply without financial burden of public sectors. Despite this project has some problems. So in this study we want to suggest some institutional improvements of the endowment & concession project. First, in order to reduce social and regional conflicts, resident consultive groups should take part in the project from the beginning. Second, an organ of consultation for the optimal development estimation and an plan guideline should be set up, for the increased amount of project cost according to the replan is a levy of planers and developers. Third, for some years ahead lots of public facilities become superannuated and redevelopment projects will last. It means the role of the endowment & concession project will be strengthened. So it is necessary to adopt relevant regulations in order to define and regulate the role of project participants clearly.

공시지가의 시계열분석을 통한 전주시 주거지 유형별 특성 고찰
유성필(Yoo, Sungphil),이문규(Lee, Moonkyu),황지욱(Hwang, Jeewook) 한국도시행정학회 2011 도시 행정 학보 Vol.24 No.4
Old city centers tend not only to decline the living condition physically but also to negatively affect the land price inclusive of the land and housing price. It even results in the inverse phenomena of the land and housing price between the area of city center and the one of its outskirt. Namely, it is regarded as a cause of deformed urban structure. In this context, this study tries to empirically investigate the alteration of the appraised land value of residential areas from 1990 to 2005 based on the time-series analysis. This investigation allows to confirm that the residential function in the area of city center goes on being weakened and concurrently urban sprawl is strengthened.
