The residential population of Jeju Island has increased more than 10% for last 10 years. Especially, the tourist population is more than twice comparing to 2005. The population growth of Jeju has brought about large-scale urban development and increased land demands for tourism services. The goal of this study is to analyze the human, social, and environmental status of Jeju Island and to evaluate the environmental capacity of land use using ecological footprint (EF) model. This study shows the changes in ecological deficits of Jeju Island through estimating ecological productive land (EPL) considering EF from 2005 to 2015. The categories of total EF consists of food land, built-up land, forestry, and energy consumption. In order to reflect the characteristics of resort island, we consider not only residential population but also tourist population who can increase land demands. The outputs of this study also provide the potential excess demands of EPL and suggest needs of sustainable management plans for the limited land of Jeju Island.

The purpose of this paper is to introduce two integrated urban development projects in Japan that take full advantage of flood-control reservoirs: the Tetsugakudo Park Collective Housing Development Project and the Koshigaya Lake Town Project. The former project - implemented cooperatively by the Tokyo metropolitan government in charge of river management, Shinjuku and Nakano wards (in Tokyo) responsible for park management, and the Urban Renaissance Agency, a housing project developer - set a significant precedent for three-dimensional river use by realizing the three-dimensional integrated development of a flood control reservoir, a park, and collective housing. The Koshigaya Lake Town Project, launched as a drastic storm water management measure for a low-lying area often plagued by flooding, has achieved a sustainable coexistence between the waterfront environment and the urban living environment, with an artificial flood-control reservoir as the core for urban development. This project is fully committed to environmental coexistence through the optimal use of local environmental resources, with the cooperation of the central government, Saitama Prefecture and Koshigaya City.

2015년 9월에 세계 각국의 정상이 UN 총회에 모여 지속가능한 발전을 위한 2030 Agenda를 구축하기로 합의하였다. 2030 Agenda에는 사회적 안전성, 경제적 효율성 및 환경적 건전성이라는 3대축을 달성하기 위한 17개의 지속가능한 발전목표(SDG)가 채택되었다. UN 지속가능 발전 구축연합(UN SDSN)에서는 SDG 실행 정도를 측정하기 위한 지속가능 발전지표(SDI)를 개발하여 빈곤퇴치, 사회적 통합, 환경관리 같은 총체적 접근을 통하여 지속가능성의 달성 정도를 확인할 수 있는 지속가능성평가(SA)에 적용할 수 있도록 하였다. 우리나라에서는 전략환경영향평가(SEIA)를 PPP(정책, 계획, 프로그램)에 환경부가 시행하는 반면에, 전략환경평가(SEA)의 일종인 국토계획평가(NLPA)는 국토교통부 자체의 계획에 적용되고 있다. SEIA와 NLPA가 고위 정책당국자를 포함한 이해당사자들에게 의사결정 지원도구로 활용되어 왔지만, 이들 SEA 제도의 핵심원리인 최적 대안 선정의 평가기준은 구체성이 미흡한 실정이다. 우리나라 실정에 적합하게 고안된 SDI를 SEIA에 반영하면 지속가능성을 비교적 간략하게 평가하여 SDG 실행의 실효성을 향상시키는데 기여할 수 있을 것으로 판단된다.

Background: Characterizing and describing soils and land use and make a suggestion for sustainable utilization of land resources in the Ethiopian Rift valley flat plain areas of Lake Chamo Sub-Basin (CSB) are essential. Objectives: To (1) characterize soils of experimental area according to World Reference Base Legend and assess the nature and extent of salinity problems; (2) characterize land use systems and their role in soil properties; and (3) identify best land use practices used for both environmental management and improve agricultural productivity. Methods: Twelve randomly collected soil samples were prepared from the above land uses into 120 composites and analyzed. Results: Organic carbon (OC) and total nitrogen (TN) were varied along different land uses and depleted from the surface soils. The soil units include Chernozems (41.67%), Kastanozems (25%), Solonchaks (16.67%), and Cambisols (16.67%). The identified land uses are annual crops (AA), perennial crops (PA), and natural forest (NF). Generally, organic carbon, total nitrogen, percentage base saturation (PBS), exchangeable (potassium, calcium, and magnesium), available phosphorus (P₂O₅), manganese, copper, and iron contents were decreased in cultivated soils. Soil salinity problem was observed in annuals. Annuals have less nutrient content compared to perennials in irrigated agriculture while it is greater in annuals under rainfed. Clay, total nitrogen, available phosphorus, and available potassium (K₂O) contents were correlated positively and highly significantly with organic carbon and electrical conductivity. Conclusion: Management practices that improve soil quality should be integrated with leguminous crops when the land is used for annual crops production.

This paper intends to raise some of urban policy issues of managing and planning Seoul for the twenty first century. As one of the world's most dynamic megacities, Seoul is faced with at least two trends: one is globalization of the economy, and the other is humanization of urban development in relation to people's quality of life. Given this context, there are emerging issues in a time of transition as the following; pedestrianization, decline of city master plan, micro land use control, citizen involvement, metro-wide management, infrastructure provisions and maintenance, sustainable development, urban information sustaniable development, urban information system, and public-private partnership.

Land-use changes due to the socio-economic environment influence landscape patterns and processes, which affect habitats and biodiversity. This study considers the effects of such land-use changes, particularly on the traditional rural "Maeul" forested landscape, by analyzing landscape structure and vegetation changes. Three study areas were examined that have seen their populations decrease and age over the last few decades. Five types of plant life-forms (Raunkier life-forms) were distinguished to investigate ecosystem function. Principle component analysis was used to understand vegetation dynamics and community characteristics based on a vegetation similarity index. Ordination analysis transformed species-coverage data was introduced to clarify vegetation dynamics. Landscape indices, such as area metrics, edge metrics, and shape metrics, showed that spatial heterogeneity has increased over time in all areas. Pinus densiflora was the main land-use plant type in all study areas but decreased over time, whereas Quercus spp. increased. Over a decade, P. densiflora communities shifted to deciduous oak and plantation. These findings indicate that the impact of human activities on the Maeul landscape is twofold. While forestry activities caused heavy disturbances, the abandonment of traditional human activities has led to natural succession. Furthermore, it can be concluded that the type and intensity of these human impacts on landscape heterogeneity relate differently to vegetation succession. This reflects the cause and consequence of patch dynamics. We discuss an approach for sustainable landscape planning and management of the Maeul landscape based on traditional management.

Beef and dairy cattle are the primary ruminant livestock in Korea, but there is a serious shortage of both fresh and dry forages. Small areas of forage crops or pastures, unfavorable soil and climatic conditions, high costs for pasture production, low establishment and management technologies, etc. are the main factors limiting roughage production in Korea. To meet the roughage demand of cattle several suggestions are presented. About 845,000 ha of hilly area could be developed for pastureland. Almost the same area of paddy field, and more than 200,000 ha of reclaimed land could be used for pasture production. If all the potential area is developed for pastureland, the area could be extended to 10 times more than is presently used for pasture crops and pastureland. Productivity would be increased by developing new technologies of establishment and management. Silvo-pastoral systems should be introduced to Korea.

공간계획에 있어서 실질적으로 전략영향평가의 역할을 담당할 수 있는 토지적성평가가 2003년부터 지방자치단체를 중심으로 시행되고 있다. 토지적성평가는 토지의 물리적 사회적 공간적 특성에 따라서 개발사업의 시행 이전에 토지의 용도를 결정하는 과정이다. 이 과정에서 토지의 특성을 파악하기 위하여 지리정보콘텐츠를 중심으로 하는 디지털DB의 활용은 필수적이며, 법률상으로도 GIS를 활용하도록 규정하고 있다. 그러나 지자체의 여건은 아직 이 제도를 실시하기 위한 물적 인적 기반이 미비한 상황이다. 이러한 문제를 개선하기 위하여, 이 연구에서는 사례연구를 통하여 토지평가를 실시하고, 이를 바탕으로 토지평가제도의 효율성과 실행성을 제고할 수 있는 방안을 강구하였다.

The condition and management of land resources has become an increasing matter of concern in recent years, because of the pressure placed upon land for agricultural use by expanding populations and economic development. Pressures upon land quality can lead to various forms of land degradation, such as in soil erosion, soil fertility decline, adverse changes in water resources, salinization of irrigated areas, or decline in the biological condition of forests or rangelands. In 1992, World Bank estimates that the cost of degraded areas has been estimated as 10-50 times higher than that of measures to prevent degradation. Based upon a survey interviewed with people living in rural areas, the present study argue that it is important to establish policies for preventing changes in agricultural land use, to provide early warning of adverse trends and identification of problem areas. The present study also stresses that stewardship of agricultural land resources plays a leading role in achieving sustainable rural development not to mention agricultural and forestry production.

1960년대 이후, 우리나라의 산업화가 급격하게 진행되고 도시가 기능적으로 개발되면서, 도시내부의 강을 중심으로 하는 수변공간은 도로건설과 비선호성시설의 집적으로 도시민의 삶의 공간에서 소외되기 시작하였다. 특히, 산업화시대인 1970~80년대에 폐수와 쓰레기로 오염된 강은 생태 친수공간으로서의 역할을 상실하고 하수구의 기능으로 전락하였다. 그러나 21세기에 들어서서 지속가능한 도시에 대한 요구와 도시의 쾌적성에 대한 수요가 증가하면서, 도시민은 도시 내에서 맑은 물과 쾌적한 수변공간을 갈구하게 되었고, 최근에는 도시재생의 중심적인 공간으로 수변공간이 주목받고 있다. 본 연구에서는 도시 수변공간에 대한 이용현황과 계획의 문제점을 살펴보고, 도시 수변공간이 갖는 입지적 특성을 바탕으로 한 수변공간 활용방안을 분석하여, 우리나라의 도시적 여건에 부합되는 친환경적이며 도시재생에 기여하는 지속가능한 수변공간의 관리방안을 제시하고자 한다.
