  • Health benefits from implementing air quality control measures were assessed using the Environmental Benefits Mapping and Analysis Program (BenMAP). BenMAP developed by US EPA is a GIS-based software tool that estimates the health impacts and associated economic values connected with changes in ambient air pollution. Once a set of BenMAP-required data was collected, the health benefits from implementing Seoul Air Quality Management Plan (SAQMP), an official AQ improvement plan for Seoul Metropolitan Area, was assessed using BenMAP. The PM10 concentrations assuming the SAQMP implemented successfully were predicted with the MM5 (Mesoscale Meteorological model version 5)/CMAQ (Community Multiscale Air Quality) model. A PM 10 exposure related premature mortality function was adopted trom a well-known epidemiology study. Economic valuation functions driven from benefit transfer methods were utilized. Through the SAQMP, PM10 concentrations were estimated to be lowered by $15{\mu}g/m^3\;to\;75{\mu}g/m^3$ depending on air quality modeling grids. 5,569 premature deaths (95% CI $3,264{\sim}7,809$ deaths) could be avoided in the Seoul Metropolitan Area. The economic value of the deaths avoided was estimated to $13.2 billion $(95%\;CI\;$890\;million{\sim}$28.2\;billion)$ using the benefit transfer value. BenMAP could be a useful tool for developing effective air quality improvement policy, enabling the policy makers to anticipate the effects of regulatory changes on people's health and the economy.

  • In Korea, open burning of agricultural residues is prevalent due to inadequate collection systems, which have caused environmental impacts such as GHGs and particulates. This illegal treatment of agricultural residues also results in economic loss, considering that agricultural residues can be utilized as resources such as pellets and energy sources. To understand the effect of avoiding open burning, this study evaluated the economic, environmental, and social effects of two alternative management options for agricultural residues: incineration and pelletizing. The study estimates the potential amount and dry weight by region for 18 items, taking various factors into account. Regarding the economic aspect, pelletizing facilities in all regions in Korea create economic benefits. This study shows that most regions have an environmental advantage by pelletizing residues. However, incineration creates more environmental benefits than pelletizing in metropolitan cities with relatively low density of residues. It is expected that the environmental, economic, and social findings of this study can be used to inform policies for bioenergy as the need for agricultural residue increases.

  • Urban forests have various environmental benefits, contributing to the quality of urban life. However, these values have been underestimated or never been reflected in the urban development planning in Korea. As a result, a number of forests in urban areas were either partly or wholly destroyed without their public's values being assessed explicitly. The objective of this paper is to estimate the economic benefits attached to Mt. Kwanggyo in the Capital Region using contingent valuation method, aiming to provide policy-makers with useful information to make an informed public decision in urban development planning. The survey was carefully designed and implemented to meet a number of recommendation rules suggested in the literature. The overall results show that the respondents well accepted the contingent market and would be willing to pay a significant amount for the proposed program of conserving the mountain. Total economic benefits for the population amounted to approximately 3.8 billion Korean won per year. This quantitative information can be used in cost-benefit analysis of urban development plans.

  • The purposes of this study were to investigate ecotourism goals which are providing educational tourism, generating environmental conservation, and residents' economic benefits based on the 7th Muju Firefly festival. The sample was 243 visitors from August 23rd to 30th, 2003. The results were as follows: First, visitors showed high satisfaction for the educational tourism program. Experiencing educational 'Mysterious Firefly Field Trips' contributed to the tourists' educational satisfaction. It was found that these experience programs were very popular. Second, residents' and domestic visitors' satisfaction was high with 5.50 on Likert 7 points concerning environmental conservation. Third, foreigners showed high satisfaction for visiting tourism sites and understanding regional culture in terms of understanding region and economic benefits. The average economic effect was decreased compared to 2002. So there should be more diverse strategy to increase economic effect. Also more festival related products, diverse and unique foods and beverages based on regional products should be developed.

  • 최근 우리나라는 댐 운영에 있어서 다양한 가뭄 대책을 활용하여 가뭄 시 물 부족의 위험 리스크를 줄이기 위해 노력하고 있다. 이를 중심으로 다양한 연구들이 수행되었지만 가뭄 대책의 효과를 경제적인 측면에서 살펴본 연구는 현재 전무한 실정이다. 본 연구에서는 ARIMA와 Copula 기반의 장기간 모의 유입량 생성 모형과 댐별 가뭄 대책을 반영한 댐 운영 모형을 활용하여 전국의 다목적댐을 대상으로 가뭄 대책 시행에 따른 경제적 효과를 평가하였다. 경제적 편익 산정 결과 연계 운영·대체 공급과 비상공급대책의 단위 유량 당 기대 편익이 각각 1,176원과 1,139원으로 가장 높 으며, 비상 용량 활용과 용수공급조정의 편익은 956원과 875원으로 추정된다. 추가로 미래에 가뭄이 심화된다는 가정을 기반으로 가뭄 대책의 경제적 편익의 변화에 대하여 살펴본 결과 유입량 감소로 인한 가뭄 리스크의 변화는 모든 가뭄 대책의 경제적 편익을 높이는 효과를 보였다. 용수공급조정의 경제적 효과는 기존 대비 2.6% 상승하였으나, 연계 운영·대체 공급의 경제적 효과는 기존 대비 11.7% 상승하였다. 이는 가뭄의 위험도가 증가할수록 연계 운영과 대체 공급과 같은 댐 네트워크 기반의 대책이 주요한 것으로 판단된다. 본 연구는 향후 가뭄 대책의 선정과 활용에 있어서 기본자료로 활용될 것으로 기대된다.

  • Up to date, the economic feasibility analysis on land consolidation and on-farm development projects were mainly depended upon the direct benefits from market value of project outputs. Therefore the projects were neglected in allocation of the government's financial funds and loans on account of undervaluation of the project benefits including socio-economic and environmental values of the projects. Accordingly the Extended Benefit Cost Analysis Method should be adapted to cover not only the benefits such as non-market values of environmental functions of the projects and but also the economic market values of the project outputs. The main objectives of this study is (1) to provision of the guideline for economic feasibility analysis based on the IBRD and ADB guidelines, (2) to estimate the benefits such as Productivity increase effect, labor saving effect, off-farm income increase effect during off-farm season, saving of O&M cost of farm mechanization, enhance of farmer's public health, increase of environmental public function of paddy fields, effect of food security and establishment of peaceful and uncontroversial rural society by implementing the land consolidation and on-farm development, (3) to introduce the newly adapted analytical method as the extended benefit cost analysis which could make possible the analysis of non-market goods such as the food security value and the environmental public value of paddy fields. To carry out the study, the publication on the guideline for economic analysis of agricultural projects were reviewed and consulted and for the post evaluation of the land consolidation and on-farm development project, field survey in Jeongja area were made for the feasibility study of the project by new method. According to the initial project plan, Jeongja land consolidation and on-farm development project has 96ha of benefit area and the project was started in 1989 and completed in the spring, 1990. The total project costs were amounted to 1,052 million won and the annual project benefits were estimated at 135.4 million in 1989 constant market prices. On the other hand, the newly estimated project benefits as a part of post evaluation of the project were amounted to 602.1 million won including all the benefits from the market and non-market commodities of the project as mentioned above column. The original IRP(Internal rate of return) of the project was estimated at 15.81%. On the other hand, the IRR of the post evaluation of the project was amounted to 16.83%. In case of including the benefit from the environment public function of paddy field, the SRR(Social Rate of Return) was reached to 38.81% and when we added the benefit from food security of the project, the SRR showed very high rate as 46.41%. In conclusion, the project were verified socio-economically feasible and environmentally sustainable considering the above decision making criteria.

  • This study presents the impact of natural flow patterns on downstream fish habitat and economic outcomes in the Dal Stream, Korea. The study reach is 3.35 km long, located downstream form the Goesan Dam. To assess such impact, this study performed physical habitat simulations. The River2D model was used for the computation of the flow and the HSI model for the habitat simulation. Two physical habitat variables, flow depth and velocity, were used. The Zacco platypus, Zacco temminckii, Coreoleuciscus splendidus, and Opsariichthys bidens were selected as the target species in the study area. Using the building block approach (BBA), the scenarios for the hydropeaking mitigation were presented. Scenario 1 and scenario 2 were proposed by using the magnitude - duration concept and averaged the hydrologic data over the each month, respectively. Simulation results indicated that the scenarios effects significantly increased by about 18.6% for the weighted usable area (WUA). In addition, hydroelectric power benefits with both scenarios were investigated. It was revealed that the change of storing and releasing water decreased by about 27% for hydroelectric power benefits. In order to increase economic benefits, the scenario was modified with the discharges corresponding to the hydropeaking condition except the flood season. As a result, the hydroelectric power benefits were almost the same, however the aquatic habitat for the target species increased by about 5%. The change of dam re-operations through natural flow patterns provides an opportunity to minimize environmental and economic benefits in order to balance water management.
