Abstract
Urbanization is a rapidly intensifying global phenomenon, reshaping landscapes and altering ecosystems across regions. In India, the foothills of the Himalayas, particularly Dehradun, has witnessed significant transformations due to urban expansion. Rapid urbanization has given rise to various adverse consequences affecting the environment, economy, and the well-being of its inhabitants. Among these challenges, land-use change stands out as a significant issue linked to urbanization. This research investigates alterations in land use and land cover (LULC) during the period from 2000 to 2020 within the Dehradun District of Uttarakhand. Forest cover degradation is one of the main threats to the area. LULC changes are determined with an interval of 5 years, that is, 2000, 2005, 2010, 2015, and 2020. Remote sensing (RS) and Geographical information system (GIS) methods detect changes in urban and forested areas using a multi-temporal supervised classification approach for generating LULC maps. The classifications reveal significant changes in the study area from 2000 to 2020. It was found that there was a decline in dense vegetation by 9.00% and an increase in built-up area by 2.32%, which may be due to the increase in urbanization and industrialization across 20 years. The outcome of current research can help significantly improve future development initiatives within the study area and is essential for the effective implementation of Sustainable Development Goal 15. The spatial analysis techniques contribute to a deeper understanding of potential strategies for prioritizing land use policies aimed at restoration at the priority level. These insights can then be extrapolated to benefit other socio-environmental tropical forest systems.
期刊介绍：
Environmental Earth Sciences is an international multidisciplinary journal concerned with all aspects of interaction between humans, natural resources, ecosystems, special climates or unique geographic zones, and the earth:
Water and soil contamination caused by waste management and disposal practices
Environmental problems associated with transportation by land, air, or water
Geological processes that may impact biosystems or humans
Man-made or naturally occurring geological or hydrological hazards
Environmental problems associated with the recovery of materials from the earth
Environmental problems caused by extraction of minerals, coal, and ores, as well as oil and gas, water and alternative energy sources
Environmental impacts of exploration and recultivation – Environmental impacts of hazardous materials
Management of environmental data and information in data banks and information systems
Dissemination of knowledge on techniques, methods, approaches and experiences to improve and remediate the environment
In pursuit of these topics, the geoscientific disciplines are invited to contribute their knowledge and experience. Major disciplines include: hydrogeology, hydrochemistry, geochemistry, geophysics, engineering geology, remediation science, natural resources management, environmental climatology and biota, environmental geography, soil science and geomicrobiology.
