This paper aims to study the impact of natural disasters on per capita income in Vietnam both the short and long-term, specifically impact loss of income caused by the extreme drought 2013 for agriculture, forestry and fishery in Phu Yen Province, Central Vietnam. The study valued economic damage by applying the synthetic control method (SCM), which is a statistical method to evaluate the effect of an intervention (e.g. natural disasters) in different case studies. It estimates what would have happened to the treatment group if it had not received the treatment by constructing a weighted combination of control units (e.g. control provinces). The results showed that the 2013 drought caused a decrease in income per capita, mainly in the agriculture, forestry, and fishery sector in Phu Yen. The reduced income was estimated to be VND 160,000 (1 USD = 23,500 VND (2021)) for one person per month, accounting for 11% of total income per capita and continued to affect the income 6 years later. Therefore, authorities need to invest in preventive solutions such as early and accurate warnings to help people to be more proactive in disaster prevention.

This study was carried out to analyze water cycle characteristics and evaluate water retention function in Jeju Gotjawal forest from 2013 to 2017. The average ratio of throughfall, stemflow, interception loss in Seonhul Gotjawal (SH) and Cheongsu Gotjawal (CS) was 43.1%, 15.8%, and 41.1%, respectively. Rainfall-throughfall, rainfall-stemflow, and rainfall-interception loss were expressed as linear regression equation (p<0.001). The comparison results showed that SH was higher than CS (p<0.05), indicating that the canopy area had an important effect on the difference in stand structure. The average water resources retention rate of the Gotjawal region was 41.9%, which is similar to the total water resources retention rate (40.6%) of Jeju Special Self-Governing Province (JSSGP). Currently, the development of Gotjawal is in progress in JSSGP. The development of Gotjawal will lead to a decrease in the water resources retention rate due to changes in the surface environment such as an increase in impervious areas, which will affect the total groundwater content of JSSGP. Therefore, the conservation of the Gotjawal area is judged to be very important from the point of view of water conservation.

The study aims to propose a locating method of green space for reducing Particulate Matter (PM) in ambient air in conjunction with its source traces and vulnerable groups. In order to carry out the aims and purposes, a literature review was conducted to derive indicators of vulnerable area to PM. Based on the developed indicators, the vulnerable areas and green spaces creation strategies for each cluster were developed for the case of Seongdong-gu, Seoul. As a result, six indicators for vulnerability analysis were came out including the vulnerable groups (children's facilities, old people's facilities), emission sources (air pollutant emission workplaces, roads), and environmental indicators (particulate matter concentration, NDVI). According to the six selected indicators, the target area was divided into 39 hexagons and analyzed to result the most vulnerable areas to particulate matter. As a result of comprehensive vulnerability analysis, the Seongsu-dong area was found to be the most vulnerable to particulate matter, and 5 clusters were derived through k-means cluster analysis. Cluster 1 was analyzed as areas that most vulnerable to particulate matter as a result of the comprehensive analysis, therefore urgent need to create green spaces to reduce particulate matter. Cluster 2 was areas that mostly belonged to the Han River. Cluster 3 corresponds to the largest number of hexagons, and since many vulnerable groups are distributed, it was analyzed as a cluster that required the creation of a green spaces to reduce particulate matter, focusing on facilities for vulnerable groups. Three hexagons are included in cluster 4, and the cluster has many roads and lacks vegetation in common. Cluster 5 has a lot of green spaces and is generally distributed with fewer vulnerable groups and emission sources; however, it has a high level of particulate matter concentration. In a situation where various green spaces creation projects for reducing particulate are being implemented, it is necessary to consider the vulnerable groups and emission sources and to present green space creation strategies for each space characteristic in order to increase the effectiveness of such projects. Therefore, this study is regarded as meaningful in suggesting a method for selecting a green area for reducing PM.

울산 도시지역 지하수의 수질 특성을 파악하기 위하여 216개의 일반 수질분석과 168개의 VOCs 분석이 이루어졌으며, 이를 주거․상업지역, 공업지역, 농업지역, 산림지역으로 구분하여 토지이용과 지하수 수질과의 관계를 분석하였다. 전반적으로 보아서 남구 태화강 저지대 일대 주거․상업지역 지하수에서 과거 해수의 영향에 의해서 Na와 Cl의 함량이 높다. NO3는 농업지역, VOCs는 공업지역 지하수에서 높은 함량을 보이기도 하지만, 토지용도별 지하수의 수질오염 특성 구분은 어렵다. 아직까지 연구지역 지하수의 오염은 우려할만한 수준은 아니나, 도시화가 계속 진행되고 있기 때문에 계속적인 관찰이 요구된다.

Nowaday special attention is being paid to the conservation of all species or ecosystmes of sites for public projects. Many environmental conservation policies and projects in Japan emphasize the coexistence of man with nature and close contact with nature. The objectives of this study was to investigate policies and projects for the creation of areas for the close contact with nature in Japan, to characterize change of techniques for the space creation over times, and to classify those policies and projects implemented by many government agencies. This study was mainly carried out by literature survey of laws, policies and projects related to environmental conservation pertinent to national scale. Major findings of this study can be summarized as follows: First, two most significant turning points for the environmental conservation in Japan were the establishment of the Office of Environmental in 1971 and the enactment of many laws influenced by the awareness of global environmental problems since 1990. Second, polices and projects for the creation of areas for the close contact with nature started in 1960s by the Office of Forestry, and focused on planting and development of simple facilities in forests. And the conservation of natural environment, ecological restoration and the expansion of urban green spaces, and the creation of biotopes and other areas for the close contact with nature in urban areas were the major characteristics of environmental conservation in Japan during 1970s, 1980s, and 1990s, respectively.

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.

Covering an area of about 39 ha, Qingming Shanghe Park is located in the northwest of Kaifeng, formerly the capital of seven dynasties in China. It is intended to serve as a tourist attraction based on a painting 〃Qingming Festival at Riverside〃 by Zhang Zeduan of the Northern song Dynasty, which vividly illustrates a real life on the both sides of the Bian River as well as in the urban area, Kaifeng, in early Spring. The park is a collection of varied buildings such as shops, restaurants, tea-houses, theaters, and hotels in the North song style, with an introduction of the history of Kaifeng, this paper examines design philosophy and methodology of the park, and discusses the creative design of the first stage development known as known as The South Area of the park. Marked by the Rainbow Bridge and the City Gate, the South Area is divided into three parts, the rural, suburban, and urban parts which are organized according to the spatial order showed in the painting. The South Area proves to be very successful because of its amazing sense of history and interesting folk performance. Furthermore, the preliminary 9planning of the second stage development known as The North Area is presented with references to culture, history and customs. The North Area is proposed to include the Old Sports & Games Garden, the Exhibition Garden, and the Hot Spring Garden with an appearance of the imperial gardens in the Northern Song, integrated with participation of old sports and games, display of old science & technology achievements, and enjoyment of hot spring bath.

도시림 개선을 위한 노력은 꾸준하게 진행되어 왔으나 사회적인 욕구를 제대로 반영하였는지에 대한 평가가 없어 향후 지속적인 개선 및 관리의 방향을 제안하기는 어려운 상태이다. 사회환경과 생물환경이 어우러진 도시림을 효율적으로 개선하기 위해서는 양적 증대 뿐만아니라 생물의 분포 및 서식, 인간의 이용성을 평가할 수 있는 연결성, 건전성, 접근성 등 질적인 측면을 동시에 고려할 수 있는 생태적 건전성에 대한 평가지표의 필요성에 따라 연구를 진행하였다. 연구는 생태적 건전성 평가시 중요한 항목에 대한 상대적 중요도 평가, 문헌고찰을 통한 세부 지표 선정, 타당성 검토의 체계를 갖는다. 결과적으로 도시림은 자연림과는 다른 기능이 존재한다는 전제로, 도시림 평가는 고유의 기능인 생태성 뿐만아니라 인간의 간섭을 고려할 수 있는 사회성, 관리성이 충분하게 고려되어야 하나 중요도에 대한 설문조사 결과 생태성이 다른 가치에 우선하는 것으로 나타났다. 이에 생태적 건전성을 평가할 수 있는 세부지표를 선정하였는데, 식생관련 지표로는 희귀성, 훼손잠재성, 자연성, 면적, 다양성, 발생기간, 야생조류관련 지표로는 숲 발달정도, 면적을 추출하여 분산분석을 실시한 결과 안정성, 자연성, 다양성, 잠재성, 서식가능성이 평가지표로 선정되었다.
