| Research Abstract |
This study aimed to develop an integrated agricultural economic and hydrological/ water quality model to analyze the effects of agri-environmental policies on farming practices and the change in water environment due to the changes in farming practices. We evaluated how the policy which Shiga Prefecture is promoting in order to reduce environmental burdens from agriculture affected the water quality in Lake Biwa Watershed. We conducted a questionnaire survey to farm households in Shiga Prefecture and revealed factors affecting farmers' adoption of environmentally friendly farming and their decision on the ratio of area allocated for environmentally friendly farming. In addition, MIKE model was constructed to estimate the change in phosphate loadings due to the adoption of environmentally friendly farming in a subwatershed of Lake Biwa. According to the model, if the payment for environmentally friendly farming were abolished, the phosphate loading would increase several percent.
