  • 급속한 경제성장과 산업화는 오픈스페이스의 감소, 환경 훼손, 교통체증, 무분별한 도시성장 등 심각한 도시문제를 야기시키고 있으며, 국토의 효율적인 보전 및 관리가 되지 않아 다양한 사회갈등이 야기되었다. 이로 인해 많은 학자와 정부는 친환경적인 계획을 수립하여 관리함으로써 지속가능한 발전을 실현하고자 노력하고 있다. 이러한 배경 하에 본 연구는 대한민국을 대상으로 미래 토지피복 변화에 따른 생태계의 기능적 변화를 분석하고자 한다. 이를 위해 통계청의 추계 인구수와 로지스틱 회귀분석을 이용한 도시성장확률지도를 작성하여 2010~2060년의 토지피복 변화를 예측하였고, Costanza의 계수를 이용하여 생태계 용역가치를 분석하였다. 분석결과 시나리오 1의 생태계 용역가치는 6,783~7,092백만 USD로 나타났고, 시나리오 2는 시나리오 1에 비하여 2.9~7.6백만 USD가 감소한 6,775~7,089백만 USD로 나타났다. 이 같은 결과는 시나리오 2의 경우 개발관점에서 도시가 성장함에 따라 상대적으로 보전가치가 높은 농업지역과 습지지역의 많은 면적이 훼손되어 생태계 용역가치가 감소하는 것으로 나타났다. 따라서 지속가능한 개발을 위해서는 친환경적이고 체계적인 도시개발을 통해 환경적 보호가 이루어져야 함을 알 수 있다. 또한, 환경정책수행에 따른 환경적 가치를 정량적으로 분석함으로써 정책입안자 및 도시개발자들에게 판단기준을 제시해줄 수 있을 것으로 판단된다. 향후 정확한 도시성장 수요량을 산정하고, 이를 바탕으로 도시성장예측모델링을 수행하여 보다 정밀한 도시성장예측 분석이 이루어져야 할 것으로 판단된다.

  • 사범대학에 개설된 교양 강의를 통해 지속가능발전목표(SDGs)와 연계하여 지속가능발전교육(ESD)을 실시한 사례를 소개하고자 한다. SDGs 13번 목표인 '기후변화 대응'과 연계하여 설계된 수업에서 42명의 예비교사들이 표출한 탄소 발자국(carbon footprint)에 대한 인식을 분석하였다. 예비교사들은 일상생활에서 탄소를 배출하는 실천 정도에 대한 체크리스트인 탄소 다이어트 다이어리를 작성하고, 탄소 발자국 그리기 활동을 통해 자신이 배출하는 탄소의 출처와 비율을 자유롭게 표현하였다. 전기 사용, 대중교통 이용, 쓰레기 처리 항목에서는 긍정적인 실천 정도를 나타내었으나, 수도 사용에 대해서는 부정적인 방향으로 분석되었다. 탄소 발자국을 2-3가지 항목으로 표현한 예비교사들이 과반수에 달하여 자신의 일상생활에서 탄소 배출 상황을 인식하는데 한계를 나타내었다. 예비교사들은 학교현장에서 지구의 환경문제를 교육하는 주체가 될 것이며, 예비교사들의 탄소 소양(carbon literacy)은 학생들에게 직간접적 영향을 미치게 될 것이다. 17가지 SDGs와 연계되는 다양한 지속가능발전교육 프로그램이 개발되고 교육현장에 적용되어 지속가능한 지구환경교육에 기여하기를 바란다.

  • 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.

  • This study is based on the need to reform mixed use plan of school facilities considering the characteristics of depressed downtown area. It started with the object to make a plan by deducting function of place required and corresponded to the characteristics of depressed downtown area in Pohang city. As the result of researching present status and the characteristics of six elementary schools in Pohang which the number of student has decreased, it is found that they are required to have change in the region of depressed downtown area which have fallen behind and obsolete school facilities which idle classrooms have increased and to have reformations of a city are characterized by 5 types as poor life environment, lack of cultural facilities as community institution, poor open-space and ecological environment, non-activation of conventional market and contraction of commerce industry by outflow of industry, transfer of administration operation function and etc. and the region of school under researching shows these characteristics. I planed the mixed use program with factors of local community facility, status of school facility use and depressed area's characteristics. Finally, I propose the mixed use plan of school facilities as the strong point of sustainable development which influences on and be influenced by regional characteristics and structure of city.

  • Fertigation, which has been introduced in agricultural fields since 1990, has been widely practiced in upland fields as well as in plastic film houses as part of the crop production system. In accordance with demands in the agricultural sector, a huge number of scientific studies on fertigation have been conducted worldwide. Moreover, with a combination of advanced technologies such as big-data, machine learning, etc., fertigation is positioned as an indispensable tool to achieve sustainable crop production and to enhance nutrient and water use efficiency. In this review, we focused on providing valuable information in terms of crop production and nutrient/water use efficiency. A variety of fertigation studies have described that enhancement of crop production did not differ relative to conventional method or slightly increased. In contrast, fertigation significantly improved nutrient/water use efficiency, with a reduction in use ranging from 20 to 50%. Water-soluble organic resources such as livestock manure and agricultural byproducts also have been identified as useful resources like chemical fertilizers. Furthermore, the initial irrigation point was generally recommended in a range of -10 - -40 kPa, although the point differed according to the crop and crop growth stage. From this review, we suggest that fertigation, which is closely integrated with advanced technology, could be a leading technology to attain not only food security but also carbon neutrality via improvement of nutrient/water use efficiency.

  • This study aimed at finding directions for Korean agriculture to establish a new paradigm of sustainable development. Various problematic issues and concerns in the environment necessitate the transformation of Korea's development paradigm from unconditional growth to "Green Growth" through new policies on green value and review of various advanced researches. In this research, the environment-friendly agriculture's problems, particularly in agribusiness were analyzed. Drawing from Michael Porter's Value Chain Analysis, this research developed a value chain model in agriculture that reflects the environment and the present situations. Future directions in the agriculture sector were also discussed. Korea realized food self-sufficiency through the green revolution in the early 1970s. However, a lot of problems have also occurred, including ground and water pollution and the destruction of ecosystems as a result of the overuse of pesticides and chemical fertilizers. In the late 1970s, the growing interest on environment-friendly agriculture led to the introduction of sustainable methods and techniques. Unfortunately however, these were not innovative enough to foster environment-friendly agriculture. Thereafter, the consumers' distrust on agricultural products has worsened and concerns about health have increased. In view of this, the Ministry of Food, Agriculture, Forestry and Fisheries introduced in December 1993 a system of Quality-Certified Products for organic and pesticide-free agri-foods. Although a fundamental step toward the sustainability of the global environment, this system was not enough to promote environment-friendly agriculture. In 2008, Korea's vision is for "Low Carbon Green Growth" to move forward while also coping with climate change. But primary sectors in a typical value chain do not consider the green value of their operations nor look at production from an environmental perspective. In order to attain sustainable development, there is a need to use less resources and energy than what is presently used in Korean agricultural and value production. The typical value chain should be transformed into a "closed-loop" such that the beginning and the end of the chain are linked together. Such structure allows the flow of materials, products and even wastes among participants in the chain in a sustained cycle. This may result in a zero-waste sustainable production without destroying the ecosystem.

  • The comparison of solar energy technologies with conventional technologies involves more than just comparing the costs of supplying energy and provding capacity. Solar technologies supply energy in a sustainable manner while having minimal effects on the environment. When choosing between solar energy technologies and conventional technologies, first cost is a important factor. The environmental and other social benifits of using solar energy technologies contrasts sharply with the environmental degradation and social costs resulting from the use of conventional technologies. These hidden costs, sometimes called "social cost", are not included in conventional economics. This paper is emphasized that the consideration of social costs effects comparisons between renewable and conventional energy technologies is of importance.
