This research article offers a comprehensive analysis of land use and land cover (LULC) alterations over a 22-year timeframe (2002–2024) surrounding Moti Jheel and Kararia Maun in Motihari City, Bihar, India. Through the utilization of detailed LULC maps, six specific categories were distinguished, namely bare land, built-up, cropland, swamp, vegetation, and water body. The outcomes of the study demonstrate significant changes primarily driven by urban sprawl and modifications in agricultural methods. Urban areas underwent a substantial increase of 80.63%, whereas cropland and vegetation witnessed notable declines of 5.84% and 52.47%, respectively. Water bodies exhibited a troubling decrease of 6.31%, indicating a substantial reduction in wetland areas, while swamp regions displayed a rise of 87.34%. The research also noted a surge in land surface temperatures (LST) associated with urbanization, as indicated by a comparative examination of LST maps dated 2002 and 2024. Various indices, such as Normalized Difference Vegetation Index (NDVI), modified Normalized Difference Water Index (MNDWI), Normalized Difference Built-Up Index (NDBI), and Normalized Difference Built-Up Index (NDBI) were utilized to provide further insights into the environmental repercussions of these transformations. These findings underscore the critical necessity for sustainable land management strategies and policy interventions to alleviate the negative impacts on local ecosystems and climate, underscoring the significance of conservation endeavors aimed at safeguarding and rehabilitating these crucial wetland areas.

This research article offers a comprehensive analysis of land use and land cover (LULC) alterations over a 22-year timeframe (2002–2024) surrounding Moti Jheel and Kararia Maun in Motihari City, Bihar, India. Through the utilization of detailed LULC maps, six specific categories were distinguished, namely bare land, built-up, cropland, swamp, vegetation, and water body. The outcomes of the study demonstrate significant changes primarily driven by urban sprawl and modifications in agricultural methods. Urban areas underwent a substantial increase of 80.63%, whereas cropland and vegetation witnessed notable declines of 5.84% and 52.47%, respectively. Water bodies exhibited a troubling decrease of 6.31%, indicating a substantial reduction in wetland areas, while swamp regions displayed a rise of 87.34%. The research also noted a surge in land surface temperatures (LST) associated with urbanization, as indicated by a comparative examination of LST maps dated 2002 and 2024. Various indices, such as Normalized Difference Vegetation Index (NDVI), modified Normalized Difference Water Index (MNDWI), Normalized Difference Built-Up Index (NDBI), and Normalized Difference Built-Up Index (NDBI) were utilized to provide further insights into the environmental repercussions of these transformations.
