  • Recently, reckless exploitation of land resources without much consideration for the environmental value of the land has been witnessed to accommodate the ever-increasing demands for regional development. Fragmentation due to land development is a major reason for the declining biodiversity in forest ecosystems. The purposes of this study were (1) to investigate the relationship between the factors of land development and forest fragmentation in 13 watersheds of a metropolitan area and (2) to suggest a forest management plan through the relationship. We carried out a factor analysis to determine explanatory axes of forest fragmentation, and then conducted a correlation analysis between the factor scores and the factor of land development, such as the rate of built-up areas, road density, number of built-up patches, and area of housing developments. The first explanatory axis represented stability of landscape highly related with the rate of the built-up area and road density. The second axis represented the level of fragment highly related with a number of built-up patches. Forest fragmentation patterns of the 13 watersheds were classified for the similarity in forest fragmentation. This study presents the forest management plans including distribution and level of land development and forest conservation.

  • By IPCC climate change scenario, the socioeconomic actions such as the land use change are closely associated with the climate change as an up zoning action of urban development to increase green gas emission to atmosphere. Prediction of the land use change with rational quality can provide better data for understanding of the climate change in future. This study aims to predict land use change of Cheongju in future and SLEUTH model is used to anticipate with the status quo condition, in which the pattern of land use change in future follows the chronical tendency of land use change during last 25 years. From 40 years prediction since 2000 year, the area urbanized compared with 2000 year increases up to 87.8% in 2040 year. The ratios of the area urbanized from agricultural area and natural area in 2040 are decreased to 53.1% and 15.3%, respectively.

  • This study begins with a question of what spatial impact international trade policy would have following the Uruguay Round, particularly focusing on agricultural trade liberalization in Korea. Based upon the neoclassical urban economic model, it first identifies the channel in which agricultural market opening can ultimately affect both rural and urban are as; $\circled1$ Free trade will depress domestic price of agricultural products, $\circled2$ which will in turn depreciate agricultural land price. $\circled3$ The decrease in marginal supply cost for urban land will then facilitate urban sprawl, provided that the government relaxes restrictions on urban-rural land conversion. Theoretical analysis is further refined by empirical considerations that distinguish agricultural land value solely for production purpose from that for future urban, uses, and that distinguish the urbanization effect caused by the fall in the supply cost of urban land from that caused by the existing high level of demand. Utilizing the estimate of bid-price for paddy field derived from the revenue-cost relationship of rice production, simulation results show that the urban-rural boundary under trade liberalization can expand outward up to 70-85km radius in the Seoul metropolitan area, suggesting the emergency of a metropolis or even a megalopolis which extends from Seoul to the central part of the country. Since the geographic extent of urbanization effect can vary depending upon the urban spatial structure, however, it is recommended that the redevelopment option in the built - up area should always be tied up with the issue of whether to deregulate rural-to-urban land conversion.

  • This paper discusses the change of land ownership in the urban historical core of Kyungju city in the Period of Japanese occupancy(1910-45) based on the analysis of land register records. Kyungju city was not designated for the cities controlled by urban planning law which was set up in 1912 and 1934. The major purpose of this paper is to clarify the urbanization process of a Korean local city where the formal urban planning projects were not carried out. The focus of the study is the increase of the Japanese landowners and Japanization of the landscape. In the very beginning of occupation, Japanese already owned about 8% of the total land of the city centre where the old Kyungju castle had been located. The ratio of the land owned by Japanese went up to more or less 70% at the end of World war II. The process which the urban core had been replaced for the Japanese is very clearly traced from the analysis of a land register records.

  • The Seoul Metropolitan Government is striving to minimize the amount of traffic according to the supply of apartment houses along with the solution of housing shortage for the low income people through high density development near the subway area. Therefore, a stronger policy is necessary to control the traffic of the passenger cars in a subway area for the successful high density development focusing on public transportation, and especially, the estimation of the demand of cars with high reliability is necessary to control the demand of parking such as the limited supply of parking lot. Accordingly, this study developed car ownership forecasting model using Look-up Table among category analyses which are easy to be applied and have high reliability. The estimation method using Look-up-Table is possible to be applied to both measurable and immeasurable types, easy to accumulate data, and features the flexible responding depending on the changes of conditions. This study established Look-up-Table model through the survey of geographical location, the scale of housing, the accessible distance to a subway station and to a bus station, the number of bus routes, and the number of car owned with data regarding 242 blocks in Seoul City as subjects.

  • Land surface temperature (LST) is a critical environmental indicator affected by land cover (LC) changes. Currently, the most convenient and fastest way to retrieve LST is to use remote sensing images due to their continuous monitoring of the Earth's surface. The work intended to investigate land cover change and temperature response inAn-Najaf province. Landsat multispectral imageries acquired inAugust 1989, 2004, and 2021 were employed to estimate land cover change and LST responses. The findings exhibited an increase in water bodies, built-up areas, plantations, and croplands by 7.78%, 7.27%, 6.98%, 3.24%, and 7.78%, respectively, while bare soil decreased by 25.27% for the period (1989-2021). This indicates a transition from barren lands to different land cover types. The contribution index (CI) was employed to depict how changes in land cover categories altered mean region surface temperatures. The highest LSTs recorded were in bare lands (42.2℃, 44.25℃, and 46.9℃), followed by built-up zones (41.6℃, 43.96℃, and 44.89℃), cropland (30.9℃, 32.96℃, and 34.76℃), plantations (35.4℃, 36.97℃, and 38.92℃), and water bodies (27.3℃, 29.35℃, and 29.68℃) respectively, in 1989, 2004, and 2021. Consequently, these changes resulted in significant variances in LST between different LC types.

  • Only 22.7% of total land area is arable land in Korea, it is anticipated that the increased land utilization of present arable land and enlargement of arable land through the reclamation of hillside and tidal land will be of great importance for the support of increased population in the future. Followings are the prediction of increased land utilization ratios, increased arable land through the reclamation of hillside and tidal land, and the increase] in fertilizer demand up to the year of 2000. 1. On the assumption that irrigation facilities, farm mechanization, and cropping systems would be improved remarkably by the year of 2000, the land utilization ratios of paddy land and upland are estimated to be 179% and 193% respectively. 2. Increments of fertilizer demand due to increased land utilization ratios, are estimated to be 2, 290 M/T in 1980, 70, 611 M/T in 1990, and 153, 619 M/T in 2000, when the amounts of fertilizers per unit area are fixed at present lrevels. 3. Increments of fertilizer demand due to the expansion of arable land through the reclamation of 516,330 ha of hillside land and 160,568 ha of tidal land, which are the present estimation of the reclaimable areas, are estimated as 32,960 M/T in 1980, 136,320 M/T in 1990, and 366,861 M/T in 2000. 4. Total increments of fertilizer demand due to the increased land utilization of arable land and the expansion of arable land through the reclamation of hillside and tidal lands in 2000's are estimated as 196,285 M/T for N, 147,351 M/T for $P_2O_5$, and 176,844 M/T for $K_2O$.

  • Despite the longing for democracy of most people, Myanmar has missed opportunities for social and economic development by military dictatorship. However, since 2010, the civilian government has gained new opportunities for reform. After turning to economic reform, developed countries such as the US and EU lifted the economic sanctions that they had taken in the past. As a result, it is growing rapidly compared to neighboring countries due to attracting foreign capital, tariff benefits on export items, and expansion of industrial infrastructure. Despite the increased investment value due to economic growth and democratization, the complex and customary land system of Myanmar must be an uneasy factor in securing stable land rights when entering overseas markets. Therefore, this study sought the method of securing the land rights in the development project through the analysis of the foreign investment system in Myanmar and the investigation of joint development cases. The results of this study are as follows. First, the acquisition of land use rights at the early stage of development can be considered through the foreign investment system. Under the Foreign Investment Law and Myanmar Investment Law, the land can be used for up to 70 years, and Under the Special Economic Zone Law, the land can be used for up to 75 years. Second, in relation to land compensation, it is required to establish a detailed resettlement plan for the indigenous people as the difficulty of land acquisition is expected due to the recent democratization trend and strengthening the voice of residents. Third, land use at the operational stage can be achieved by leasing the land from developers, and this will be the most realistic plan at present. In other words, the developer can directly develop the land created under the Foreign Investment Law and the Special Economic Zone Law, or Sub-lease and transfer the land use right to a third party.

  • The influence of land-use type on surrounding temperature was studied the relationships between land-use types and the air condition analyzing AWS (Automatic Weather Station) data of Seoul from KMA (Korea Meteorological Administration). The distribution of air temperature by land-use type has been influenced by the different heating and cooling rates. The difference of heating rates depending on the land-use type was largest at 2~3hours after sunrise and the difference of cooling rates was largest from 2hours before sunset to 2hours after sunset with its maximum at sunset. The difference of cooling rates is greatest in a clear and calm weather situation and the large difference in cooling rates between the green areas and built-up area is up to $1.5^{\circ}C/h$. By season, the difference of cooling rates is largest in fall and in turn spring, winter and summer. In a cloudy or rainy day, the difference in heating and cooling rates on land-use type is not distinct but the tendency is similar to a clear day. In all seasons, the rate of difference occurrence of the daily range of temperature between the green areas and built-up area was large, especially fall. In a fall with a clear and calm day, the magnitude of the daily range of temperature between the green areas and built-up area was largest.
