[Abstract]

　The objectives are to identify each effect of global warming on urban environment and infrastructure and to systematically assess integrated impacts including interrelation and/or multiplication of each effect. Effects of global warming on urban environments in many cities in the world were reviewed and their information was input to the integrated knowledge-base system including fuzzy model. Individual information related to global warming effects on urban environment was integrated into it systematically.
　The landfill technology method for reducing greenhouse effect gas emissioned from municipal solid waste landfill site was studied. Aerobic landfill cell and anaerobic landfill cell were set up on the scales, respectively. The amounts of gas emissioned from each cell were evaluated based on mass balance. The empirical models were derived from these experimental data and applied to actual landfill sites. It was found that the contribution of the semi-aerobic landfill site decreased by the half of the anaerobic landfill site.
