This study comprehensively examines flood vulnerability in the rapidly developing peri-urban areas of North Bhubaneswar, focusing on significant changes in Land Use/Land Cover (LULC) and hydrological dynamics from 2004 to 2024, utilizing Geographic Information System (GIS) tools. The analysis reveals substantial shifts in land use patterns , with the urban footprint expanding by 71.8%, cropland decreasing by 21.7%, and forest areas by 13.6%. These changes have led to increased impervious surfaces, resulting in higher surface runoff and decreased groundwater recharge, thereby exacerbating flood risks in the region. The GRID-based vulnerability analysis classifies 90 villages within the catchment area based on their vulnerability levels, identifying 20 villages as high-risk areas requiring urgent attention, 44 villages as medium vulnerable, and 26 villages as low vulnerable. These classifications are based on factors such as proximity to drainage networks, slope, geomorphology, and LULC characteristics, with areas near drainage channels and low-lying regions being prone to flooding. The analysis integrates multiple factors to provide a comprehensive assessment of flood risk, highlighting the need for sustainable land use planning, conservation of vegetated areas, and the implementation of advanced flood prevention strategies in the peri-urban areas. Extending this research to other fringe regions could offer further valuable insights, guiding flood prevention and sustainable development strategies for areas undergoing significant land use transformations to effectively mitigate future flood risks.

The present study analyses the temperature modulations from 2000 to 2022 in Kalarahanga and Raghunathpurjali fringes in North Bhubaneswar to understand the relationship between spatiotemporal changes and land-surface temperature in the fringes. The investigations reveal a consistent decrease in the area under water bodies and crops, with an increase in the builtup area. Besides, there exists an inverse correlation between the area under high and medium temperature with the area under cropland (-0.820) and the area under water bodies (-0.799), and a positive correlation coefficient (0.813) with the built-up area/impervious surfaces. This insists on eco-sensitive planning of the urban fringes with consistent monitoring of land use and thermal dynamics for apt control of the changes in the urban microclimate.

It addresses the question, of how climate change affects agriculture particularly the cropping patterns in the mining context of Odisha, India. The changes in cropping patterns directly impact the livelihoods of the population, who depend on agriculture. The study covered the major crops in the district from 2004-05 to the 2018-19 seasons by utilizing secondary data and intersecting it with primary data gathered from farmers in the district. The data was analyzed using descriptive methodology and primary data was collected through the Focused Group Discussions (FGDs) tool in the Hemgiri Block of the Sundargarh district. The results revealed several factors that directly contributed to changes in cropping patterns, including climate change, government projects, mining activities, and market dynamics. A decline in paddy crop area was observed with a shift toward the cultivation of pulses, oilseeds, and fruits such as mango and cashew. Overall, these findings indicate a significant change in agricultural preferences and a shift among farmers toward high-value economic crops.

The escalating population of the city along with massive influxes of migrants, is triggering unplanned, uncontrolled, and unrestricted urban sprawl, which is contributing to exorbitant changes in the spatial footprints of the city. It is irony that although being surrounded by rivers on three sides of the city, ground water resources are based for domestic, industrial and agricultural uses due to lack of piped water supply system in many parts of the urban area and the fringes. The rapid growth of the city has led to profound pressure on the precious groundwater resource degrading both quality and quantity. In addition, most of the unsewered parts of the urban areas are elevating the nitrate and other contaminants in the groundwater. The remediation of the resource under incessant threat by both contamination and inappropriate use may be practically impossible in future. Since trend detection of hydrologic data is useful in the investigation of water quality parameters, in this study, eight physical chemical variables of groundwater quality of Bhubaneswar obtained from Odisha Pollution Control Board from 2010 to 2017 were analyzed using the non-parametric Mann-Kendall test. Spatial variations of Sen Slope displaying the positive values with large magnitude in the Secretariat area indicates that the groundwater quality is declining at a higher rate. The quality may not be an issue presently but may be alarming in next few decades
