Evaluating the impact of climate change on urban environment using geospatial technologies in the planning area of Bilaspur, India

Abstract

Worldwide fertility rate is becoming a most significant context of anthropological condition. Rapid population pressure is one of the increasing factors for global land crisis and gradually effect in the environment and boosting the climatic vulnerability. Rapid urbanization, industrialization and technologically build-up area created more land scarcity in worldwide. Many administrative authorities extended the urban area due to extreme population or people migrant another parts of some area. Bilaspur planning is situated in Chhattisgarh state, India. Population pressure is increased urban expsansion over the Bilaspur city. This study is to focus out that land use and land cover change (LULCC), thermal variation in the Bilaspur planning area using remote sensing and geographic information system (GIS). Multi-temporal Landsat imagers were used to identifying the urban expansion in the last 40 years (1981–2020). Population pressure, change in the urban household, climate change and extreme events area change the agricultural land and forest area into built-up land. An urban agglomeration is increased transportation accessibility and also enlarged the traffic volume. The findings shows that the urban area has been expended around 47.9 sq. km between 1981 and 2020. Basically central, south, north and north-western parts has been experienced a huge amount of urban development and decreased vegetation and forest land due to anthropogenic activities. The annual UHI increased 0.11 while UTFVI high values were located 0.0206 (1981) and 0.0326 (2020), which is indicated the ecological condition in Bilaspur. This study may helpful for the urban planners, administrators and policy makers for sustainable development and urban planning of Bilaspur area.
