  • It is difficult to examine the causal relation of pollution damages because the time gap between pollution cause and effect is large and new pollutants are continuously being produced. Their many environmental effects are not promptly studied. As both the study of causal relation about pollution and the pollutant treatment are becoming highly advanced by the development of science and environmental technology, both the economy and balance on environmental regulation may be discussed. It is reasonable to decide environmental policy in consideration of close relation between both the generation and resolution of environmental problems and of technological developments because environmental problems are related to complicated social problems and scientific technologies. First item in policy decision about environmental control and management is preferentially to consider the way of prevention. It is necessary to prevent pollution by regulating the installment of environmental pollution facility into the environmentally sensitive areas, like water supply source and to regulate land utilization as a method to achieve pollution prevention. Second is a consideration of environmental technology development. This is a solution which can accomplish the development of environmental technology and the reinforcement of economic competition. Third is the coexistence of environment and economy. It is necessary to consider economy in connection with environmental problems and environment in economic problem. Then, we can enjoy a healthy life as well as economic affluence. Fourth is the enlargement of environmental management means. Environmental management means must be diversified because environmental cause and effect are varied. For Improving the land use regulation system, it is necessary to consider both land use regulation status and pollutant toxicity with the development of environmental technology. Land use must be approached by classifying land to 3 levels; water source protection zone and water front zone, special zone 1 and 2, rancus and other zones. Land regulation policy to prevent any accident in water source protection zone, waterfront zone, and special zone must be continuously upgraded. However, economical consideration in other zones is required by the development of environmental technology.

  • Many problems were found out the remarkable unbalance between paddy fields and up-land areas, or between plain and mountainous areas, unreasonable establishing of land consolidaton boundaries without consideration of rural development, lower leverl of construction technology of the roads and canals for agricultral use ad operation and maintenance of them by human power far apart from the ages of high technology, high information and free internationalisation, and too slow progress to overcome the weak agricultural circumstances etc. through the survey in the past executed land consolidation projects. The basic ways for solution of these problems for propulsion of land consolidation project through investigation are summarized as follows : 1. Land consolidation project should be executed to the direction of balanced regional development, laying stress on the upland and mountainous areas in order to carry out the agriculture effectively. 2. the acreage of land consolidation project to be conducted anually should be increased to overcome the serious underdeveloped agricultural development. 3. It should be developed to the way in accordance with the order of land use from the view point of rural integral development including the rural readjustment. 4. The level of the structures of road and canal, the size of standard lot and the grouping of land substitution should be to incraese the productivity of land and labour more than ever and reached to a degree in cope with the age of industrialization, information and free internationalisation. 5. The level of the management of agricultural water use and the maintenace of the various facilities should be developed to be automatization, remote control, central control and information processing instead human work. 6. Land substitution should take a measure of grouping method in accordance with the agricultural plan and farming organization, which can overcome high industrialized society in place of the substition by origin land. 7. Land consolidation project should be planned in order to fulfil a conservative function of ecosystem and resources together with improvement of land and labour productivity.

  • The purpose of this study was to determine the problems of reclamation sites and the prospects of farming in reclamation areas seen by local governments and the KRC branches in Chungnam, Jeonbuk, and Jeonnam provinces. A mail survey method was used. The survey items were set for 15 items regarding the reclamation site situation, problems, and prospects. Seventy-five copies of the questionnaire were distributed to the local government, and 90 copies were sent to the KRC 165 copies in total. In response to the questionnaire, 72 recipients of the local governments responded, showing a 96% response rate, and 74 (82.2%) of the KRC responded. The overall response rate was 88.5%. The opinions on the rental method of the reclaimed land were found to differ according to the geographic conditions of the reclaimed land, the construction conditions, and the time. Regarding the survey on crops preferred for cultivation, rice was highest in both local governments (61%) and KRC (46%). When cultivating field crops in reclaimed land, 56% of local governments and 57% of KRC considered salinity as the most problematic or resolvable problem. Regarding growing other field crops in reclaimed land, salt and drainage problems were recognized as the biggest obstacles in all reclaimed land. As for technologies that need to be applied first for the future agriculture of reclamation land, KRC responded with automatic water management (48%) and local governments responded with unmanned agricultural machinery (32%). In order to diversify the land use in the reclamation area, it is necessary to reduce salt damage and ensure systematic maintenance, employing, for example, automatic water management facilities and drainage improvement methods. The results of this study can set a land use direction for reclamation sites and provide useful information for use in various forms.

  • This study proposes a legal limit from the administrative and management standpoint of the city hall/county office/gu office, which is the cadastral authority, in relation to the discrepancy between the actual land use status and the cadastral study that has been continuously raised. And also, from the point of view of civil complaints such as landowners, this study tried to evaluate the practical problems of the current land category system from the point of view of civil complaints such as landowners and to derive a solution to these problems. Therefore, this study indicates how the category of land use is classified, and how land use is restricted by the laws of Registration & Management of public cadastre. Also, it shows the reasons why discrepancy between the land use fixed by the law and the current state of actual use of land occurs. Addtionally, This study suggests a plan to reorganize the Land Category system and it includes consolidation and subdivision of land. The study also describes a way to minimize the targets for conversion of land under control of Land Category System as well as to improve the law that protects the people's property rights.

  • Land suitability assessment has been enforced by the National Land Planning and Utilization Act since 2003 to prevent urban sprawl and protect natural environment. It assesses developmental, agricultural or preservable suitability of land parcel according to such criteria as soil, location and usability by local governments. Land suitability assessment system (LSAS) has been introduced to prevent cursory development by urban sprawl and to lead a harmonious development with conservation in the non-urban area. However, with the lack of experience and knowledge various problems have been arisen in the operation of this system, raising a question for the improvement of the assessment unit of land. The purpose of this study is to investigate methods of developing land assessment as a sustainable land use management tool. In this study, land suitability assessment has been executed through geographic information systems. On the basis oh the results of analysis, practical and institutional problems are described, and technical and institutional solutions are suggested.

  • This paper pointed out major problems of land use regulation policy surrounding Paldang Lake as follows: (1) inefficient management system, (2) inconsistent administrative management, (3) illogical selection of regulated area, (4) contradictory present system, and (5) controversial discharge control. Several regulation laws for the land-use surrounding Paldang Lake caused confusion of application and inefficiency of management. Amendment of regulation laws made it possible that the regulated area was developed, which resulted in the deterioration of water quality. In addition, successive regulations without scientific implementation overexpanded regulated area and focus on the discharge concentration of contaminated sources stimulated development of small size sources. To overcome these problems, we suggested reestablishment of regulated area, differentiation of regulation amendments, and flexibility in the application of regulation. It is necessary to arrange regulated area based on the efficient land use management and scientific implementation and then to mitigate land use regulation under the sustainable development. For the flexible application of regulation, it is required to amend the rule in response to the change of environmental condition and development of environmental techniques.

  • The land cover map represent the state of earth surfaces. It can be used as basic data to explore present conditions of earth surfaces and develop future plans for local areas. To produce the land cover map with efficiency, gathering geographic information from satellite images is important. Exporting, building, and managing processes on the land cover information are needed as well. In this study we aim to review the producing process of the level-2 land cover map in detail and enhance it. h present status of the producing process of the land cover map in Korea is reviewed, problems of the process are explored, and measures for improving it are proposed. The criteria for fixing boundaries and providing attributes for the land cover map are proposed. This proposed criteria may solve problems in a present producing process. The improving measures proposed in this study should be continuously revised in future studies.

  • In Korea, It was natural and inevitable to reclaim tidal land for farming due to over-population in small territory. Looking back upon the history of tidal land reclamation in Korea, We can find the first case of it in 13th century KangHwaDo(Island), and also find several records of small scale reclamations of western sea-coast from Korea dynasty to Chosun dynasty. A lot of wide fertile agricultural areas on western sea-coast have been developed through tidal land reclamation for about 1000-year after Korea dynasty. and on these areas, we have produced rice which we live on. An average areas of farming land per capital in korea is only 0.04ha, which is one sixth of global average. For water resources, similarly, capacity of water resources alloted to one person is $11{\%}$ of global average. So, without supplementary water development, we will have suffered from a severe deficiency of water Therefore we must prepare for these predictable short water and food problems. and tidal land reclamation may be suitable alternative to settle these problems. However, tidal land reclamation is a work of closing estuary, intercepting sea water inflow, developing a freshened estuary lake and farming lands etc. therefore it apparently causes a change of ecosystem, water quality and littoral environment. Nowadays, widely recognized the importance of environmental preservation, it is desirable or requested to make phil-environmental and sustainable development minimizing the environmental influence due to tidal land reclamation project. In this paper, the role of tidal land reclamation project in the development process of Korean agriculture was reviewed and the direction of afterwards tidal land reclamation project was suggested.

  • 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.
