| Abstract | Land use is one of the leading factors that cause environmental degradation, such as water pollution, open space contraction and habitat loss. This dissertation consists of three essays. First paper investigates the relationship between land use and water pollution. Combining land use choice model and water pollution data, I simulate the effects of the policies that changes returns to land uses such as afforestation payments in five watersheds in Japan. From this simulation, I derive abatement cost of chemical oxygen demand, total nitrogen, and total phosphorous and I reveal that afforestation payment is best policy for most of pollutants and regions but in some regions it increases chemical oxygen demand. The cost data is then compared with abatement cost from upgrading and construction of sewage treatment plants to compare relative efficiency and show that combining both policy is sometimes more efficient that single policy. The second essay focuses on one watershed in Japan and I analyze the effect of the subsidy that promotes eco-friendly agriculture using fixed effect panel. Using budget as abatement cost, policy effect is estimated and compare it with land use subsidy and sewage treatment construction and upgrade cost. For my study area, afforestation payment is most cost effective while investing sewage treatment plants are least cost effective but the result depends on existing sewage treatment plants and regional characteristic. The third model focuses on land use and open space. Even though previous study (Bento et al. 2006) revealed that a tax and an urban growth boundary is equivalent in terms of efficiency. When I relax assumption by adding uncertainty and heterogeneity in soil quality, I show counterexamples of equivalence of two policies. |
