  • This study was conducted to develop the evaluation model which can analyse local agenda 21 comprehensively and systematically from the making process to the designed contents. The evaluation model was devised through the theoretical review of local agenda 21 and designing the evaluation system composed of evaluation domains, related indicators and scales. The evaluation system was carefully constructed based on planning theories and the discussion and agreement of specialists regarding local agenda 21. This model has three evaluation domains of process, content, and evaluation of implementation with different weighting values. Each domain contains large indicators, medium indicators and small indicators. Each indicator has different weighting value according to its importance. Basically, each small indicator was scored by 3 or 5 point scale. This evaluation system can not only analyse local agenda 21 quantitatively, but also find out good points, problems, and limits of various phases of planning and implementing local agenda 21.

  • Winter migratory birds gather in paddy rice fields to feed shed rice grains. The Korean Ministry of Environment has practiced a policy program Contract on Paddy Field Management (CPFM) during winter fallow since 2002. This program starts with a contract between local governments and farmers, and the government pays a differential subsidy to farmers who finish spreading rice straw, cultivating barley, letting the whole rice plant without harvest, and submerging paddy fields for winter migratory birds. As more local governments have operated CPFM program, the total area on the contract and subsidy budget has increased yearly since 2002. This program could have its stable position as a successful policy by giving profits to farmers. With the program extended, the population of winter migratory birds has been greatly. For the evaluation of environmental performance of a policy, we analyzed this CPFM program by introducing some indicators in the form of Driving Force-State-Response Framework. The indicators were composed of 3 categorized indicators; the area of paddy land contracted under this program as 'driving force' indicator, population of birds, the number of bird species and the amount of feces as 'state' indicators, and the size of monetary support, the number of farmers or local governments participating, and public perception as 'response' indicators. The contract area of paddy field under CPFM could be a good biodiversity indicator reflecting potential performance of this policy measure in the light of its linkage to the population of winter migratory birds. And the share of CPFM land of the whole agricultural land might also be used as a useful indicator of policy evaluation for improvement of wildlife diversity. The 'state' indicators such as population of birds and the number of bird species could be matched to 'driving force' indicator, but the total CPFM area of each site could not reflect the effect of areas under different management practices. However, the amount of bird feces could reflect differences in environmental performance with management practices as 'state' indicators. The development of indicators indicating 'response' such as farmers' behavior, public perception, and policy makers' willingness is also needed to support a successful implementation and improvement of this policy measure with the development of 'performance' indicators integrating all these indicators.

  • This study aims at choosing indicators to measure the effect of utilizing biotop map, and analyzing its effect by an indicator from the perspective of performer. The Primary performance indicators are made through specialist survey using SMART. As a result, three indicators are chosen: "Discussion of the period of an environmental effects evaluation(reduced effect)", "Plan and execution of environment and ecology plan in an urban development site", "Minimizing ecological damage in an urban development." The result in each indicator is as follows. The indicator of discussion of the period of an environmental effects evaluation(reduced effect), the average reduction rate in statistically meaningful level reduced 6.08% and 11.64% respectively in 2004-2005. In this period, environment information system was established and the reduction effect is shown in this period by reinforcing environment effect estimation using biotop map. As to the indicator of utilizing biotop map in an urban development site, the Seongnam P site case shows that biotop map was used when they set up an development plan. In case of minimizing ecological damage in an urban development, the Gwangjingu G-dong case shows that it was used to appoint preservation sit, and mediate development restrict area. Accordingly, the biotop map utilizing effect is confirmed through core performance indicators and verification of the indicators using SMART. The further research is encouraged to find evaluate indicators and verify the effect quantitatively to increase the use of biotop map.

  • Considerable amount of resources on roads, basic infrastructure, to promote economic development and distribution of goods is invested. Despite the necessity, its undesirable side effects are various environmental problems In order to efficiently evaluate these problems more than before, planning indictors for environment-friendly road constructions is proposed in this study. First, we make an investigation into real-life cases where the extracted planning indicators were applied. Second, it is suggested that an alternative assessment method efficaciously evaluate and/or adopt extracted planning indictors on road construction projects. Finally, criteria to determine environmental impacts with respect to planning indicators and apply them into real cases is proposed. This study has its significance in upgrading past pro-environmental indictors for road construction, suggesting reasonable applications of planning indicators, and setting criteria to determine environmental impacts based on planning indicators.

  • Photochemical air quality models are essential tools in predicting future air quality and assessing air pollution control strategies. To evaluate air quality using a photochemical air quality model, emission inventories are important inputs to these models. Since most emission inventories are provided at a county-level, these emission inventories need to be geographically allocated to the computational grid cells of the model prior to running the model. The conventional method for the spatial allocation of these emissions uses "spatial surrogate indicators", such as population for mobile source emissions and county area for biogenic source emissions. In order to examine the applicability of such approximations, more detailed spatial surrogate indicators were developed using Geographic Information System(GIS) tools to improve the spatial allocation of mobile and boigenic source emissions, The proposed spatial surrogate indicators appear to be more appropriate than conventional spatial surrogate indicators in allocating mobile and biogenic source emissions. However, they did not provide a substantial improvement in predicting ground-level ozone(O3) concentrations. As for the carbon monoxide(CO) concentration predictions, certain differences between the conventional and new spatial allocation methods were found, yet a detailed model performance evaluation was prevented due to a lack of sufficient observed data. The use of the developed spatial surrogate indicators led to higher O3 and CO concentration estimates in the biogenic source emission allocation than in the mobile source emission allocation.llocation.
