A case study on Local Scale Urban Heat Island in Sub Urban Region of India

At present, the metropolitan cities are monotonously facing Urban Heat Island (UHI) effects all over the world. UHI effect is a kind of heat accretion phenomenon that leads to so many problems in urban areas. The impact of UHI effect is even getting worse due to improper urbanization, inappropriate planning and designing of towns. Not only metropolitan cities are encountering a high UHI effect, the developing suburbs are also expected to experience the destructive impact on health and well beings, so sub urban area are also under the threat of global warming and UHI effect. The main purpose of this study is to evaluate the various divergent mitigation strategies using urban microclimate simulation model for a part of the surveyed region.

1. INTRODUCTION The term “remote sensing (RS)” is defined consistently with Webster’s dictionary as “detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance.” [1]. Urban ecology revolves around the relation of living organisms with each other and their surroundings in the context of an urban environment. The urban environment refers to environments dominated by high-density residential and commercial buildings, paved surfaces, and other urban-related factors that create a unique landscape dissimilar to most previously studied environments in the field of ecology. The goal of urban ecology is to achieve a balance between human culture and the natural environment, one application of remote sensing for urban ecology is to detect the productivity of an area by measuring the photosynthetic wavelengths of emitted light and on the other end, with the help of satellite images, we can detect differences in temperature and landscape diversity to detect the effects of urbanization [2].
