Tokyo, Japan, one of the fastest growing cities, has faced urbanization and significant pressure from both the transportation network and the population. It is critical to understand the clear relationship between human activity and environmental effects.
This study examines the time period between 1975 and 2005, and how Tokyo's greenspace has been depleted. This research project will examine whether major variables (town size, roads development, train and subway development, housing units, population, and people's in-migration) have a strong relationship with depletion of the greenspace. This research project includes a statistical analysis to test the relationship between each variable and greenspace lost. Road development and population had a significant relationship with respect to the greenspace lost. In order to preserve greenspace, in addition to the existing rooftop greenspace policy the city of Tokyo should implement new regulations in the future.
