Abstract
This study is funded by project of Environment Protection Agency entitled “Economic Analysis of Amending Soil pollution Control Standards – A Case Study of Farmland”. Pollution survey was served to 319 hectares of agricultural land of the nation. The detection concentrations of heavy metals in the target agricultural lands were between the monitoring criteria and legal criteria. The odds of annual examination fee of those target lands were discussed before and after serving of amended Soil Pollution Control Standards. Further, the remediation cost was compared with the benefit of cultivation. The feasibility of this study was also analyzed by net present value method and benefit-cost ratio method. ithout the risk assessment of control limits, 674 million NT dollars is necessary for 649 sites exceeding the control criteria. The net income by cultivation of these 649 sites is about 17.6878 million NT dollars, an average of about 38 years to repay. In terms of net present value and benefit-const ration method, the minimum acceptable ratio and capital recovery are both 1%.With the risk assessment of control limits, 492 million NT dollars is necessary for 518 sites exceeding the control criteria. The net income by cultivation of these 518 sites is about 14.4166 million NT dollars, an average of about 34 years to repay. In terms of net present value and benefit-const ration method, the minimum acceptable ratio and capital recovery are both 1%. ccording to the result, the remediation cost funded by the government to assist the improvement of farmland will be a good strategy for the reusing of polluted farmlands. The renting of the amended farmlands is both beneficial to the government and framers in terms of the income of renting and cultivation.
