Patiala: The researchers at IIT Ropar have conducted a study on the rapid growth of urbanisation including the coming up of infrastructures and build-up areas in the Tricity "The rapid urbanisation is raising an alarm in the tricity and would leave an adverse impact on the environment and vegetation in the coming decade," says study.The researchers said that the rapid urbanisation has led to complex problems, including a reduction in vegetation cover, the formation of the urban heat island effect, environmental pollution, reduced open space, a boost in slum areas and many other factors.This study intends to explore the spatial patterns of urbanisation and its impact on the environment in and around Chandigarh. The build-up areas in SAS Nagar, Kharar, Mullanpur, Panchkula , Mohali, and Zirakpur have witnessed 79 percent increase in last 25 years. The scholars said that it is expected by 2030, that the Tricity will witness a rise of more than 30 percent in urbanisation which will probably leave a drastic impact on various accounts. The study will be carried out further for over a period of one year during which the researchers will come up with more classification of the urbanisation and its impact.According to the United Nations , the current world population of 7.6 billion is expected to reach 8.6 billion in 2030 out of which 5 billion will be urban population. The main reasons for urban growth are an unorganised expansion, increased immigration, and population explosion. In this context, changes in land cover are considered one of the central components for managing natural resources and monitoring environmental impacts.Reet Kamal Tiwari, assistant Professor at civil engineering department, IIT Ropar, said, "Chandigarh was originally planned for a population of 5 lakh, but the city has expanded rapidly over the last four decades and faces issues like proliferation of slums and squatter settlements." The study has been conducted on the basis of the Remote Sensing data collected from ISRO.
