In Kapasia Upazila, situated in the Gazipur District of Bangladesh, groundwater is a vital resource for domestic and agricultural activities. Unfortunately, the region suffers from an acute groundwater crisis, especially during the dry pre-monsoon period. This study aims to identify the spatio-temporal shifts of water levels along with the shifts occurring in agricultureAgriculture, vegetation, and livelihoods. The primary aims and objectives of the present study are to evaluate the socioeconomic impactsSocioeconomic impact of water scarcity, assess the seasonal variationsSeasonal variation of groundwater levels, measure the land surface temperatureLand surface temperature (LST), and vegetation health as depicted by NDVINormalized Difference Vegetation Index (NDVI). Using a mixed methods approach, remote sensingRemote sensing LST, NDVI, and groundwater levels mapped in ArcGIS 10.8, Landsat 8 imagery alongside corporeal data collected from 250 questionnaire surveys, 10 FGDs, 5 expert interviews and 10 water level sensor data from bore-well across three seasons in 2024 were utilized. Results have indicated that there was significant reduction in groundwater levels during the pre-monsoon season in the central and southern parts of Kapasia. This was observed to be accompanying by a fluctuation in LST and a decrease in NDVINormalized Difference Vegetation Index (NDVI). These ecological stressors were associated with lowering crop yieldsCrop yield, higher irrigation expenditures, postponed sowing dates, and alterations in cropping schedules. Socioeconomic consequences included reduced crop yieldsCrop yield (70.4%), escalated time spent fetching water (49.2%), and increased overall electricity expenses (44.4%), and increased water costs (61.6%). This research also deals with policies and planning strategies developed guided by the seasonal impacts of groundwater on agricultureAgriculture, vegetation, and rural living.
