Unplanned land use, that is, unplanned development, causes various negative externalities. In the past, Korea has experienced significant socio-economic costs due to reckless development centered on the boundary between urban and non-urban areas.. Unplanned land use can be viewed as a result of the interaction of various factors.. Therefore, it is difficult to develop in areas where unplanned land use occurs intensively. It is necessary to strengthen legal and institutional measures so that negative externalities do not persis. In this study, we present a spatial analysis methodology to effectively find spatial clusters where unplanned land use is concentrated. By demonstrating and applying this to individual development activities that occurred in Asan City, we examine the usefulness of information to support decision making when establishing mid-to-long-term growth management strategies at the local government level.

Land Suitability Assessment System(LSAS) that was introduced to prevent unplanned development of the nation is divided by Assessment System I and II. Assessment System II can regulate the land use on the development that was defined in the 'National Land Planning and Use Act'. With it, Property right can be limited in the development of private sector and this lure the investor to fabricate the result of land suitability assessment. Because of it, if we can't prepare the overview standard, we couldn't accomplish our purpose that unplanned development prevention and efficient land use. With the suggestion of overview standard for the each factor used in LSAS and the analysis result of it, we presented ways to efficient support and the fixations of LSAS.

In 2003, "The National Land Use and Planning Act" (NLUP Act) was enacted unifying two old laws; "The Urban Planning Act" enacted in 1962 and "The National Land Use and Management Act" enacted in 1972. One of main reasons of unifying two acts was to extend urban planning-based development systems to rural areas for preventing uncontrolled urban sprawl in rural areas and enhancing or settlling plan-based land use system in rural areas. This paper is conducted with the following specific objectives: i) to critically review the contents of NLUP Act in terms of rational rural land use planning; ii) to evaluate plan-based land use practices in rural area by NLUP Act; iii) to appraise performance level for prevention against unplanned development activities in rural areas by NLUP Act. To accomplish these objectives, we surveyed actural state of rural land use and development system by the new act in two case study areas. Ansung city in Gyeongi province as an urban sprawl region and Hamyang county in Gyeongnam Province as a remote rural area. Study results ascertained that the new act can not effectively control rural land use and not prevent over-use of agricultural land in the positive and effective ways because of followering three points.

According to increasing the value of real estate and various land use by urbanization and industrialization, the importance of land use has enhanced regardless of above or below the surface. Therefore the changes into Digital Cadastre using high-technical surveying methods has tried to find a solution in the purpose of providing accurate land information to End-users in real time. However Korean cadastral system was established for a short time through the Land & Forest project and it has been used for cadastral surveying until now. Land devastation by the Korean war and the indiscreet land use by unplanned land development of industrialization has raised failures to construct correct cadastral records. So it has occurred that it becomes one of social problems due to the current unmatched areas between adjacent parcels. Therefore government has tried to make an effort to solve the problems such as reducing unmatched areas and introducing a Case study for Cadastral resurvey. And also it is necessary to adopt a suitable Korean model for Cadastral resurvey. In this study, the current Korean situation of cadastral surveying was investigated and the optimized models for various patterns of Land surveying was offered.

It is focused on the desirable development alternations for sprawled unplanned on mountainous hilly areas in the residential areas development of the rural areas, mainly on the idyllic housing residential areas. The major research findings were as follows : (1) 85% of the idyllic housing residential areas of the suburban rural area was developed on the mountainous hilly areas. (2) For the desirable development on the suburban rural area, Environmentally Symbiosis Land Use Plan, diversification of Housing type such as Earthing Row House, diverse housing site planning techniques considering the conditions of mountainous hilly areas, for common space planning, land development, housing planing, hillside development, should be devised. (3) New regulations of strengthening construction permits, District Plan should be introduced in law and system management.

Accurate knowledge of land use/land cover (LULC) features and their relative changes over upon the time are essential for sustainable urban management. Urban sprawl growth has been always also a worldwide concern that needs to carefully monitor particularly in a developing country where unplanned building constriction has been expanding at a high rate. Recently, remotely sensed imageries with a very high spatial/spectral resolution and state of the art machine learning approaches sent the urban classification and growth monitoring to a higher level. In this research, we classified the Quickbird satellite imagery by object-based image analysis of Dempster-Shafer (OBIA-DS) for the years of 2002 and 2015 at Karbala-Iraq. The real LULC changes including, residential sprawl expansion, amongst these years, were identified via change detection procedure. In accordance with extracted features of LULC and detected trend of urban pattern, the future LULC dynamic was simulated by using land transformation model (LTM) in geospatial information system (GIS) platform. Both classification and prediction stages were successfully validated using ground control points (GCPs) through accuracy assessment metric of Kappa coefficient that indicated 0.87 and 0.91 for 2002 and 2015 classification as well as 0.79 for prediction part. Detail results revealed a substantial growth in building over fifteen years that mostly replaced by agriculture and orchard field. The prediction scenario of LULC sprawl development for 2030 revealed a substantial decline in green and agriculture land as well as an extensive increment in build-up area especially at the countryside of the city without following the residential pattern standard. The proposed method helps urban decision-makers to identify the detail temporal-spatial growth pattern of highly populated cities like Karbala. Additionally, the results of this study can be considered as a probable future map in order to design enough future social services and amenities for the local inhabitants.

The Land Suitability Assessment(LSA) that was introduced to prevent the unplanned development was viewed from it has applied the same assessment factor on inland and island that has a many different spatial and physical properties, it have many problems. To study the efficient LSA in island that has an totally different spatial, local properties, assessment unit(AU) which the zone of life was considered and on this based, assessment factor was developed. In the AU, middle sized life zone was the best AU to present the regional land properties. In the distance analysis, distance analysis that considered sea was suggested and use it, we ran present the assessment method that was considered the access between islands.

A phenomenon in the unplanned urban sprawl of Cheong-ju city has to be rest-rained from disposing and to develop, though progress in urbanization inevitably decreases rural area. So, this thesis aims at reviewing, revising and guiding toward the more effective land use planning practice and zoning mechanism and system of Cheong-ju city. I proposed that land use planning should be had several factors and thereupon that Korean zoning mechanism and system including Building Code should be amended because of inducing human activities in buildings and facilities not to demarcate and plan every one of them. First, the factors of urban planning are a rather diversified approach to it than a unified, supplementation of the applicable difference in time between preparing and appling it, a solid controlling system, a micro and macro planning theory and giving serious consideration for the inertia from the existing land use. Second, the applicable amendments for our zoning mechanism including Eluding Code are as follows; a need of reorganization for Zoning Ordinance appricated to different regulation concerning a scale and peculiarity of a oily, a decision of the different earmarked confinement in area to different zone ana from Zoning Ordinance in City Planning Law, a demarcated facilities and the more detailed land use concerning human activies than the exsisting and entrusting decision on the ways and processes of it to every rural city planning committee, a settlement of zone ana area considering for block-unit and Planned Unit Development(P. U. D.), and a need of security jurisprudence in order to solve the zoning regulation rather in City Planning Law than in Building Code that our zoning regulation and controlling system are depended on. According to these applicable amendments to Cheong-ju city, I proposed the conceptions of Cheong-ju city land use planning are as follows; a reinforcement with one cored pattern of urban land use, a selection of gradual urban sprawl by way of city development and renewal, a strengthening accessibility to the core of the city with Plurizing the system of arterial roads, a choice of priority to conservation at the core of tile city and security of open spaces and parking area at the area of the city, a harmonization between development and conservation at the inner ring area that is situated between the core and periphery reserved area in order to develop in the future, a buffered open space situated at the congested area with heterogenous functions, and a completion of urban open space system. The proposal made here so far is for the hope of the better structure of Cheong-ju city that should be granted to the peculiarity developed with educational, cultural, conservative and self-sufficient city functions.

This study focuses on the impact of government deregulation policies since the early 1990s on the change of industrial location anti the accompanying problems, especially of land use and environment. Since 1960s, the planned industrial location has played a leading role for the development of industrial location. However. since mid-1990s, individual(unplanned) industrial location has been increasing, especially in semi-agricultural area and in the Capital region, reflecting the impact of the deregulation policies on the industrial location. The effective policies are required to solve the problems caused by the increase of the individual industrial location. in that the standard of the environmental control for individual industrial location is much lower than for the planned industrial location.

Rising urban flood patterns are a universal phenomenon and a significant challenge for city government and urban planners worldwide. Urban flood problems range from relatively localized incidents to substantial incidents, which lead to cities being flooded for a few hours to several days. Therefore, the effect may be widespread, such as the temporary displacement of individuals, disruption to civic facilities, water quality degradation and the possibility of epidemics. The problems raised by urban flooding are highly challengeable and compound by ongoing climate change, with adverse implications for changes in rainfall and gaps in intra-urban rainfall distribution. Unplanned construction and invasions of large houses along rivers and watercourses have interfered in natural rivers and watercourses. As a result, the runoff has risen in proportion to the urbanization of the urban floods. The location of the relief camp and the priority for evacuation were determined, and the safest route to avoid floods were established. This method can be used for emergency planning in future flood incidents, and it will help plan disaster preparedness for Panchayat. This study will promote the flood plain's potential use for disaster management and land use planning virtually.
