Predicting Future Land Use and Land Cover Changes and Their Effects on Land Surface Temperature in Chattogram City of Bangladesh
Heatwave is one of the most dangerous “natural hazards” with the greatest impact on people and other living beings that rarely receive adequate attention worldwide. Climate change & intense landcover conversion result in extreme heatwaves in urban areas. Chattogram, which is located in the southeast of Bangladesh, is a prominent coastal city and key economic hub. Chattogram City Corporation (CCC) consists of 41 wards with a large population, and most of the heavy, medium, and light industries of Bangladesh are situated in Chattogram. Due to this commercial and industrial development, and rapid urbanization, the landcover of the CCC area has changed expeditiously which is responsible for the urban heatwaves hazard. The study intends to comprehend the future heat wave scenario. For a better understanding of heatwaves, it has been analyzed the temporal changing and relationship between the Land Surface Temperature (LST) and the Land Use & Land Cover (LULC) from 2000 to 2020. Based on this data, the Artificial Neural Network (ANN), Markov chain model (MC), and Cellular Automata (CA) models have been applied to the prediction of future LST and LULC in different two years, 2030 and 2040. The temporal analysis result shows that the LST of the CCC area has risen with the decrease of vegetated areas and water bodies. The model simulation result suggests that the total buildup area of the CCC will be increased around 45% and 60% in 2030 and 2040 respectively, and 13 and 43% of the CCC area will suffer temperatures higher than 36° C in 2030 and 2040, respectively which are considered to be more vulnerable to the people. Policymakers will find this research useful in interpreting the effects of LULC change on LST and in recommending management frameworks. It will also be favorable for analyzing future vulnerability in the CCC area due to heat stress.
