Impact of Urbanization on Biodiversity Hotspot: A Case of Bhubaneswar City
Abstract: Urbanization has contributed to pollution and generation of waste heat leading to changes in the urban heat balance thereby influencing its microclimate. Urban regions confront heightened heat wave conditions due to urban heat island (UHI) impact, which is a result of anthropogenic effects on both surface and atmospheric temperature patterns relative to the natural environment. The investigation was carried out in a 20-km radius around the city of Bhubaneswar. The …

Impact of Environmental Degradation on Steel City of Odisha: A Geospatial Approach
Abstract: Earth has always had an abundance of natural resources, but as the number of people on the planet grew, so did their needs, and they were taken from the environment at an ever-increasing rate. Depending on the kind of pollutant, the duration and intensity of exposure, as well as other elements like an individual's health risks and the combined effects of several pollutants or stressors, the effects of air pollution …

Remote Sensing and GIS-based Analysis of Land Surface Temperature Dynamics and Land Use Changes in Vijayawada, India
Abstract: The alteration of land use/land cover (LULC) has significant environmental consequences since it is strongly linked to long-lasting land degradation and leads to diverse environmental alterations. It is crucial to monitor the locations and distributions of changes in land use and land cover (LULC) to comprehend the connections between government actions, policy choices, and resulting LULC activities. Modern systems for protecting the environment and managing natural resources now depend heavily …

Assessment of Urban Heat Island Using Geospatial Technology: A Case of Titilagarh City, Odisha
Abstract: A phenomenon known as an urban heat island (UHI) occurs when temperatures in an urban area are greater than those in a nearby rural area. The main causes of this temperature differential are urbanization, human activity, and the construction of artificial infrastructure like buildings and roads in place of natural landscapes. Titilagarh, a city in Odisha, is often referred to as one of the hottest places in the state, making …

Urban Green space Site Suitability analysis of Angul City, Odisha – A Geospatial Approach
Abstract: The urban ecological system is crucial for human survival in cities. Residents receive various services directly or indirectly from the functions of ecosystems, known as ecosystem services. Heat stress in urban areas can be particularly harmful, as the negative effects of increasing urbanization lead to significant temperature changes that impact both vulnerable species and human health. While there are several methods, such as modifying roof materials and using lighter colors, …

Forecasting Climate-Driven Healthcare Demand in Agricultural Regions: A Multi-Modal AI Approach
Abstract: The rapidly increasing instability of world climatic regimes has made past meteorological thresholds irrelevant, especially in the agricultural areas where monetary stability and well-being of humans are closely intertwined with an environmental situation. The more the frequency of 1 in every 1000-year events, i.e., heatwaves and catastrophic flooding increase, the greater the rural healthcare systems are in crisis, i.e., unable to predict a surge in demand because of data scarcity, …

Remote Sensing and GIS-Based Approaches for Soil Salinization Assessment: A Comprehensive Review
Abstract: Soil salinization, a critical environmental challenge, significantly impacts land productivity, agricultural yields, and contributes to desertification, particularly in arid and semi-arid regions. Early detection and effective management of soil salinity are essential for sustainable agriculture and land management. Remote sensing (RS) and geographic information systems (GIS) have emerged as indispensable tools for mapping, monitoring, and analyzing soil salinity over vast areas. RS provides multi-temporal and multi-spectral data that helps identify …

Geospatial Assessment of Land Use and Land Cover Changes in Debrigarh Wildlife Sanctuary, Odisha: A Twenty-Year Perspective
Abstract: Among the recorded dynamic processes on the surface of the earth is the change in land use and land cover (LULC) pattern as an outcome of several anthropogenic practices. Planning, development, and management of land for sustainable usage of land depend on plotting and tracing the vagaries in LULC. Anthropogenic activity, generally for forestry and food production, is altering the land surface. The steadily diminishing landscape also has tragic implications …

Integration of Multispectral Satellite data with Ensemble Machine Learning Models for Wetland Classification: a new Ramsar Site in Central India
Abstract: For biodiversity conservation, several wetlands in India have been classified as Ramsar sites, and Sirpur Lake is a recent addition to the list. The objective of this paper is to use Sentinel optical data with 10-meter resolution to prepare a robust and accurate classified map which will be crucial for further analysis. The data on thirteen spectral bands along with four essential spectral indices, Normalized Difference Vegetation Index (NDVI), Normalized …

Seasonal Dynamics of Coastal Landscapes: A Critical Review Using Remote Sensing and GIS
Abstract: Coastal landscapes are among the most dynamic environments on Earth, undergoing continuous transformation due to both natural processes and anthropogenic activities. In India, particularly along the southern coastal regions of Andhra Pradesh, Tamil Nadu, and Kerala, shoreline morphology and sediment transport patterns are significantly influenced by seasonal monsoons, cyclones, storm surges, waves, tides, and changing river discharges. These factors contribute to varying rates of coastal erosion, accretion, inundation, and land- …
