Abstract
For the purpose of including consideration of environmental impact of pesticide use in decision support system, method of extracting management information, which integrated both environmental and economic indicators from selected agricultural technology, was proposed. The procedure, which outputs both environmental and economic indicators simultaneously by inputting agricultural technology information, was designed. Then risk score of agricultural technology for pesticide use (RST) as indicator of environmental risk of pesticide use was proposed in order to perform the designed procedure. RST value can be calculated by adding up the risk score of farmland for pesticide use (RSF) values about the agricultural technology. RSF value, which was estimated on the basis of the toxicity and operating density of an agricultural-chemicals active ingredient, can be calculated for the chemical substances subject to PRTR. Thereby the possibility of pesticide use impact can be quantified about agricultural technology. The designed procedure was applied to agricultural technology data on the farming-systems database and numerical result was examined. As a result, by using both of indicators integrative, it becomes possible to relate a technical selection with the load to environment by using pesticides. The proposed method in this study will offer the useful management information about the technology assessment and farm planning.
