To derive the relative contribution of woodland area and amount of anthropogenic heat emissions to temperature formation from Eq. (2.1), we obtained Eq. (2.2), which applies when the Y-value is identical to the intercept. Here X1 is the woodland area (m2) and X2 is the amount of anthropogenic heat emission (GJ/day): 0.0001 (Xi) = 0.0033 […]

Results of Multiple Regression Analysis Using Temperature as the Dependent Variable
Based on the results of correlation analysis of temperature data and factor data, we performed multiple regression analysis using the mean maximum daily temperature in August as the dependent variable. The size of woodland area and amount of anthropogenic heat emissions, which correlated highly with mean maximum daily temperatures in August, were used as explanatory […]
Results of Correlation Analysis of Temperature Data and Factor Data
Table 2.4 lists the results of correlation analysis of temperature data and factor data. Negative correlations were present between the mean daily maximum temperatures in August and woodland area and between the mean daily maximum temperatures and green spaces. Positive correlations were present between the mean daily maximum temperatures and the amount of anthropogenic heat […]
Results of Categorizing Factor Data by Cell Size and Temperature
Tables 2.2 and 2.3 list factor data by cell size and temperature, calculated in accordance with the procedure described in the research methodology. However, because of the presence of sea breezes and transportation systems (cars and railways), abnormal values that would always affect the temperature are very likely to be recorded at some of the […]
Results and Discussion
2.3.1 Collected Temperature and Factor Data, and Mesh Data Results The mean temperatures in Minato-ku in August are shown in Fig. 2.5. Some of the temperature data and factor data used in this study are described as follows. Temperature data were obtained in August 2007 from readings taken by digital weather stations set up at […]
Methods
Minato-ku is the ward located in the southeastern part of Tokyo that faces Tokyo Bay to the east (Fig. 2.1). The total area of Minato-ku is 20.34 km2 as of October 1, 2008. As of April 1, 2010, the population of Minato-ku, according to the Basic Resident Registry, was 202,505 residents. The diagram in Fig. […]
Cooling Potential of Urban Green Spaces in Summer
Kochi Tonosaki, Shiro Kawai, and Koji Tokoro Abstract The urban heat island phenomenon has recently become a serious subject of public concern. This chapter aims to clarify the cooling potential of urban green spaces in summer. At first, it shows that green space and anthropogenic heat emission have a great effect on the temperature in […]
Symposia at the 8th World Congress of IALE in Beijing
In August 18-23, 2011, IALE organized the 8th World Congress in Beijing, China, a highlight event for us to summarize our project in intermediary terms. It was good timing to develop ideas on designing low carbon societies. The first author and his collaborators organized three symposia in the congress. Their titles and organizers are “Urban […]
Development of Low Carbon Technologies
Land-use change, such as developing agricultural crops on farmlands (Abdullah and Nakagoshi 2008) and oil palm plantations (Johaerudin and Nakagoshi 2011), is one of the primary causes of forest loss in Southeast Asia. These human impacts also affect global warming through the loss of carbon sinks and subsequently increased CO2 emission. The relationship between these […]
Development of New Energy from Residual Biomass Resources
To utilize biomass at a high efficiency as a renewable energy source and to contribute to the mitigation of global warming by a great reduction of CO2 emission are fields of interest with urgent consequences. Especially, if economical technologies can be established to utilize residual wood biomass from ecosystems, a large amount of woody biomass […]
