Tracking Land Use and Land Cover Change in a Changing Climate: A Geospatial Perspective over the Mayurakshi River Basin
摘要
Climate change has reshaped land use/cover (LULC) patterns in recent decades, altering ecosystems, agriculture, and urban areas. The present study examines the effects of selected climatic factors such as temperature, rainfall, and actual and potential evapotranspiration (AET and PET) on LULC patterns in the Mayurakshi River Basin from 1993 to 2023. The necessary data were procured from NASA Power and USGS Earth Explorer in this analysis. It reveals that significant changes are evident as forests give way to urban and agricultural expansion. These LULC changes contribute to local microclimate alterations, creating feedback loops that intensify environmental degradation. LULC change analysis showed a substantial forest cover decline of 875 km2, with agricultural land expanding by 889 km2, and built-up areas increasing more than eightfold. To analyze and validate the trends of selected climatic parameters, the ‘Mann-Kendall test’ and ‘Sen’s Slope’ estimators were considered. The findings indicated a notable warming trend extending from the northwest to the southeast. Both AET and rainfall showed declining trends, particularly in the lower region. PET showed a basin-wide increase—highlighting growing climatic water stress. Correlation-regression results demonstrated that intense LULC transformations are negatively associated with rainfall and AET trends, while positively correlated with PET, suggesting that LULC alterations are contributing to regional drying tendencies and reduced moisture recycling. Integrating statistical tools with remote sensing data, this study monitors and predicts LULC changes, offering critical insights into climate change-sensitive areas and supporting sustainable land management. This enables a detailed assessment of LULC change and climate interactions. The study highlights the importance of adopting sustainable approaches to manage land and water resources effectively. The study provides empirical evidence for policymakers and planners to support adaptive land governance and resilient development strategies, contributing to the broader discourse on climate change, land degradation, and sustainability.
