This research outlines the estimation of comprehensive urban development intensity (CDI) and comprehensive eco-environment stresses (CES) along with a comparative evaluation of CDI and CES in the form of a coupling degree (CD) model. A statistical analysis of twelve Indian cities was considered to gather data, which would help generalize the correlation between urban density and environmental stress. The Fuzzy Analytic Hierarchy Process (FAHP) identifies land urbanization ratio (LUR), i.e., percentage of impervious area concerning entire area and COD (Chemical Oxygen Demand) (CODI) discharge per unit area as the principal sub-indices representing CDI and CES respectively for further analysis. In the year 2017, r-value of 0.872 was estimated between CDI and CES using Karl Pearson coefficient of correlation methodology. It was also observed, except Guwahati and Surat, all other cities were loaded with the highest level of urbanization with an immediate effect on proportional intensifying environmental stress. The CD classifications of cities showed most of the cities were designated as high (H) class of urbanization. This research's output showed the environmental status of each city with its growing urbanization and demanded to interrupt the trend of environmental degradation. Such kind of classification of CDI, CES and CD will be beneficial for researchers and urban planners in dealing with cities that will be dwelling as metropolitan territories in days to come.
