  • Efficient spatial planning is one of the necessary factors to successfully respond to climate change. And researchers often use LULC(Land-Use/Cover) data to conduct land use and spatial planning research. However, LULC data has a limited number of grades related to urban surface, so each different urban structure appearing in several cities is not easily analyzed with existing land cover products. This limitation of land cover data seems to be overcome through LCZ(Local Climate Zone) data used in the urban heat island field. Therefore, this study aims to first discuss whether LCZ data can be applied not only to urban heat island fields but also to other fields, and secondly, whether LCZ data still have problems with existing LULC data. Research methodology is largely divided into two categories. First, through literature review, studies in the fields of climate, land use, and urban spatial structure related to LCZ are synthesized to analyze what research LCZ data is currently being used, and how it can be applied and utilized in the fields of land use and urban spatial structure. Next, the GIS spatial analysis methodology is used to analyze whether LCZ still has several errors that are found in the LULC.

  • With the purpose of preventing improper development on the national land, the land development permission system which is performed from 2002 has meaning as a type of limiting the property right, but modification on the details of traditionally understood land ownership is inevitable. Also, releasing the development prohibit on the land not only stop in recovering the freedom for land development, but also can be interpretated as a cause of forming the land development right, therefore the purpose of this study is to develop this into a real right. When we look at the development activity permission as a form of limiting the property right, constitutional problems of basis for that limit and compensation demand can occur. However, that limit can be recovered or relieved through permitting the development activity, therefore the compensation problem can be solved. Due to the development activity permission system, the land development right was separated from the land ownership to be communalized, and now, the land ownership only has condition use right left and don't have the future condition change right in principle, therefore modifying the traditional concept of land ownership is inevitable. By the virtue of the land ownership authority, the land development permission system must have the property to separate the development right as the independent right to be authorized of its legitimacy. Without these properties, the land development permission system cannot satisfy the social necessity of the land development right and its discussion under the category of the land ownership limit theory can't be deviated. In the existing "Civil Law" or in the Land Regulation Law system, there are many difficulties and limits in generalizing the land development right as a real right. Therefore, it is considered that by establishing a social law idea of Framework Act on the Land to characterize the land right theory in the real right theory, the land development permission system or the development right theory should be studied and developed independently and systematically.

  • Due to constant development and decline on Seoul areas the Seoul government is pushing various policies to regenerate declined Seoul areas. Theses various policies lead to land-use changes around numerous Seoul districts. This study aims to create prediction model which can foresee future land-use changes and while doing so, tried to derive various influential factors which leads to land-use changes. To do so, various open-data from national departments and Seoul government have been collected and implemented into random forest algorithm. The results showed promising accuracy and derived multiple influential factors which causes land-use changes around Seoul districts. The result of this study could further be implemented in policy makings for the public sectors, or could also be used as basis for studying gentrification problems happening in Seoul Area.

  • Land development policy in Korea, characterized by its supply-oriented policy, has driven rapid economic development. However, it has a negative impact on the natural environment across the country. Especially, as the introduction of quashi-farmland system with the deregulation of agricultural land development in the late 1990s, numerous unfavorable landscape features such as road, motels and apartment have emerged in the rural area. As those interfered irreversible rural landscapes have been expanded, the demand for well preserved rural landscapes have been increased. The objectives of this study, thus, is to suggest the mitigations between the land development and conservation of natural landscape. As such, this study examines the recognition of current rural landscape management status through 118 students with two groups of landscape architecture majored (50 people) and non-landscape majored (68). Both group express the negative impression of current rural landscape management system in general and they pointed out the major landscape problems are caused from inappropriate land use. However, in detail those two groups respond differently, for example, the first group selected the damaged landscape is the second cause of the landscape problem, while the other group selected the poorly maintained settlements. Based on the analysis of the survey, this study suggests 3 recommendations in order to improve the sustainable rural landscape as establishing the proper rural land use planning system, building local governments' capacity to actively participate in the rural landscape management, and preparing the landscape management plans considering area distinctive characteristics.

  • In recent years, increases in impervious areas with rapid urbanization and land use changes are causing numerous hydrologic and environmental problems. In this study Low Impact Development (LID) was applied to investigate changes in runoff and peak runoff with LID plans. SWMM 5.0 was used to simulate LID Integrated Management Practices (IMPs) at study area. The SWMM estimated total runoff volume with conventional land use planning is (82.3%, 46.44 mm), (99%, 73.16 mm) greater than total runoff before urbanization, while total runoff with LID is (11.1%, 46.44 mm), (49%, 73.16 mm) greater than those before urbanization. With the LID adoption in land use planning, pervious area increases by 49.8% compared with that from the conventional urban land use planning, resulting in (32.7%, 46.44 mm), (23.6%, 73.16 mm) decrease in total runoff, and (32.6%, 46.44 mm), (18.5%, 73.16 mm) decreases in peak rate runoff. The results obtained from this study indicate that peak rate runoff, time to peak, and total runoff can be reduced with the LID in urban land use planning because the LID secures pervious areas with various LID IMPs. The SWMM simulated result using design storm data and the US EPA suggested CN values for various LID IMPs implies that how environment-friendly urban land use planning with the LID adoption is important for sustainable development at urbanizing watershed.

  • Vietnam is the second-largest coffee exporter in the world. Most of the coffee areas are concentrated in Dak Lak-a province of commercial agricultural production, making up 32.4% of the total coffee area in Vietnam. At present, coffee is the main income source for the province, with coffee accounting for 85% and 40%(2010) of the export value of the province and of the country, respectively. Although the rapid development of Dak Lak's coffee production significantly benefits the province and its coffee planters socioeconomically, emerging urgent problems such as land dispute among ethic groups need to be addressed. This paper aims to examine how coffee-production development in Dak Lak has affected land mobility. In addition, we consider how these changes have affected the livelihoods of the Kinh-the majority ethnic group in Vietnam-as well as the ethnic minorities. As a result, it is pointed out that the coffee development in Dak Lak creates the individual ownership on land. This ownership is more and more fortified when the encroaching land of the Kinh immigrants happens impetuously defying the customary law of the ethnic minorities.

  • The purpose of this study is to employ a method called 'conflict impact assessment' to analyze the progress, background, cause and relevant issues of conflicts related with affordable housing for youth (Happiness Housing Project), a project that has been implemented since last May 2013, thereby identifying the relevant problems and draw out objectives for improvement. The researchers expect that this study will contribute to solving the current issues regarding Happiness Housing, and contribute to improving the quality of the government's policies. For the above purpose, literatures on Happiness Housing produced from August to November 2013 were reviewed, in-depth telephone or face-to-face interviews were conducted with personnel associated with project implementation in the Ministry of Land, Infrastructure and Transportation and LH, etc., and major interested parties including Yangcheon-gu residents. Key issues identified regarding Happiness Housing construction include: the way that the project was implemented, living quality of residents, impact on educational environment, inconsistence with existing plans, relatively high construction cost, insolvency of public corporations, land use fee issue with Korail, need of preliminary feasibility survey, securing sufficient amount for supply and issue of additional designation, likelihood of finishing construction in time and issues related with actual source of demand, etc. Through analysis of conflict development and positions of interested parties, the main causes of the conflicts were identified as follows: lack of deliberation on pledges during election, lack of viability review on pledges, lack of conflict management plans, one-way implementation without consent of interested parties, project plans established with no regard to local circumstances, frequent project revision, underwehlming level of conflict management. In order to address issues above, the following measures need to be taken: selecting election pledges based on actual effectiveness, thorough assessment on pledges by relevant departments, gradual implementation based on consideration of the actual circumstances, participation of key interested parties, consistent policy and adopting conflict management techniques that reflect the reality.

  • The compensation data for submerged land have been filed in the form of document or managed with spread sheet like Excell up to now. In the case of dam or highway construction, huge compensation data for the submerged or included land have been managed inefficiently by the administrative manpower. Moreover, where and how to keep the enormous data becomes big problems. In response to the requirements, an submerged land compensation management system based on the location and property information of parcels was developed. The compensation management system has many functions including site searching for compensation, compensation money computing, and compensation data managing. It is expected that the submerged land compensation management system creates various information effects.

  • Since the government-owned land is the national property, the country is responsible for the management. Although one can see the recent activities of government to efficiently manage and maintain the government-owned land, its characteristics are not well reflected on the current managing methods. Obviously, efficient and prefer methods for the field survey is necessary for efficient management. In this study, the current management methods focused on the site srvey are analyzed and problems are deduced. Basically the current methods depending on the graphic information and cadastral survey results are compared with real illegal occupancy case. The investigation clearly shows the necessity of the cadastral survey and proved the current method is not sufficient to detect illegal occupancy on government-owned land. It is expected that this study contributes on establishing an efficient management methods for the government-owned land.

  • Residential land development projects are tending upwards recently. However, an indiscreet residential land development has tended to damage environment by destroying existing green lands and trees of target lands and generating many cut slopes with transformation of its topography. There are Prior Environmental Review(PER) for district designation and Environmental Impact Assessment(EIA) before approval on development plans. PER is implemented after developing a residential land development plan and EIA is implemented after completing a detail design. As the result, many of residential land development projects are passive to reduce potential environmental problems on the designated sites. Object of this study is to construct an evaluation system on alternatives in the early step of site designation for implementing residential land development projects with environment-friendly and sustainable way. For this, alternative evaluation model is constructed by using Fuzzy Inference and Analytic Hierarchy Process(AHP) method based on Environmental Evaluation Factors of residential land development project, which are proposed in the precedent research. If a decision maker evaluates environment damage by ten-point method, the point is transformed Environmental Performance(EP) by Fuzzy Inference, and then, applying weight that is already calculated by AHP method, Total Environmental Performance(TEP) is calculated. After all, an alternative with the highest TEP is selected as the best one. Using this evaluation system, more than two alternatives of residential land development project site, which can hold location appropriateness in the early under undecided land use plan, can be evaluated quantitatively. As environmental damages, which can be generated by implementing a residential land development project, can be detected in the early step, environmental damages can be removed or reduced at the source.
