Land use and land cover change (LULCC) is among the most apparent natural landscape processes impacted by anthropogenic activities, particularly in fast-growing regions. In India, at present, due to impacts of climate change, supplemented fast pace developmental areas providing highest agricultural yields are facing threat either extinction or use. This study assesses LULCC fastest-changing region Indian state Bihar, District Muzaffarpur. district known for its litchi cultivation, which,...
The Kaziranga Eco-Sensitive Zone is located on the edge of Eastern Himalayan biodiversity hotspot region. In 1985, National Park (KNP) was declared a World Heritage Site by UNESCO. Nowadays, anthropogenic interference has created significant negative impact this national park. As result, area under natural habitat gradually decreasing. current study attempted to analyze land use cover (LULC) change in using remote sensing data with CA-Markov models. Satellite and geographic information...
In contrast to other natural disasters, droughts may develop gradually and last for extended periods of time. The World Meteorological Organization advises using the Standardized Precipitation Index (SPI) early identification drought understanding its characteristics over various geographical areas. this study, we use long-term rainfall data from 14 rain gauge stations in Vietnamese Mekong Delta (1979–2020) examine correlations with changes rice yields. Results indicate that winter–spring...
Rivers play a crucial role in nutrient cycling, yet are increasingly affected by eutrophication due to anthropogenic activities. This study focuses on the Barato River Hokkaido, Japan, employing an integrated approach of field measurements and Sentinel-2 satellite remote sensing monitor as river experiencing huge sewage effluents. Key parameters such chlorophyll-a (Chla), dissolved inorganic nitrogen (DIN), phosphorus (DIP), Secchi Disk Depth (SDD) were analyzed. The developed empirical...
West Lidder River, in the Northwest Greater-Himalayan mountain range, is major source of irrigation and drinking water supplies for Kashmir Valley with a population seven million people. The whole River snow icemelt emanating from its two subcatchments East Lidder. Snowmelt significantly contributes to evolution drainage patterns this area. Quantitative morphometry plays vital role routing snowmelt other hydrological processes. Morphometric analysis catchment was carried out using geospatial...
The precursors of deterioration immaculate Kashmir Himalaya water bodies are apparent. This study statistically analyzes the deteriorating quality Sukhnag stream, one major inflow stream Lake Wular. Statistical techniques, such as principal component analysis (PCA), regression analysis, and cluster were applied to 26 parameters. PCA identified a reduced number mean 2 varifactors, indicating that 96% temporal spatial changes affect in this stream. First factor from explained 66% total...
Urban floods are very destructive and have significant socioeconomic repercussions in regions with a common flooding prevalence. Various researchers laid down numerous approaches for analyzing the evolution of their consequences. One primary goal such is to identify areas vulnerable risk reduction management purposes. The present paper proposes an integrated remote sensing, geographic information system (GIS), field survey-based approach identifying predicting urban flood-prone areas. work...
To monitor the spread of novel coronavirus (COVID-19), India, during last week March 2020, imposed national restrictions on movement its citizens (lockdown). Although India’s economy was shut down due to restrictions, nation observed a sharp decline in particulate matter (PM) concentrations. In recent years, Delhi has experienced rapid economic growth, leading pollution, especially urban and industrial areas. this paper, we explored linkages between air quality nationwide lockdown city using...
Inhabitants of low-lying islands face increased threats due to climate change as a result their higher exposure and lesser adaptive capacity. Sagar Island, the largest inhabited estuarine island Sundarbans, is experiencing severe coastal erosion, frequent cyclones, flooding, storm surges, breaching embankments, resulting in land, livelihood, property loss, displacement people at huge scale. The present study assessed change-induced vulnerability risk for India, using an integrated...
Globally, estimating crop acreage and yield is one of the most critical issues that policy decision makers need for assessing annual productivity food supply. Nowadays, satellite remote sensing geographic information system (GIS) can enable estimation these production parameters over large areas. The present work aims to estimate wheat (Triticum aestivum) Maharajganj, Uttar Pradesh, India, using satellite-based data products Carnegie-Ames-Stanford Approach (CASA) model. Pradesh largest...
Urbanization is an unavoidable process of social and economic growth in modern times. However, the speed with which urbanization taking place produces complex environmental changes. It has affected surface albedo roughness soil, thereby modulating hydrological ecological systems, turn regional local climate systems. In developing countries South Asia, rampant unplanned created a system adverse scenarios. Similar case India. The state urban environment across India degrading so quickly that...
Planning for a sustainable future involves understanding the past and present problems associated with urban centers. Rapid urbanization has caused significant adverse impacts on environment natural resources. In cities, one such impact is unsettling growth, resulting in heat island (UHI) effect, which causes considerable positive feedback climate system. It can be assessed by investigating relationships between Land Use/Land Cover (LULC) changes land surface temperature. This study links...
Rapid urbanization has led to the emergence of slums in many developing and industrialized nations. It degrades quality life burdens urban amenities resulting uneven distribution slums. The majority people world live squatter settlements these random gatherings disrupt economic social developmental plans concerned country. No suitable planning framework been created for replicability on a considerable scale, despite fact that slum upgrading is acquiring worldwide importance as political...
Bank erosion hazard is a frequent occurrence that poses threats to floodplain ecosystems. This analysis examined changes the Jia Bharali River channel in India using GIS-based Digital Shoreline Analysis System [DSAS]. The Bharali’s future was predicted so as identify most erosion-susceptible zones. rate of bankline movement calculated remotely sensed data collected over period 45 years (1976–2021). results show river’s and deposition rates were higher early than towards later part under...
The alteration of land use and cover caused by human activities on a global scale has had notable impact ecosystem services at regional levels, which are crucial for the survival welfare beings. Merbil, small freshwater wetland located in Brahmaputra basin Assam, India, is not exempt from this phenomenon. In present study, we have estimated shown spatio-temporal variation service values response to years 1990, 2000, 2010, 2021, predicted same 2030 2040. Supervised classification CA-Markov...
In September 2014, Kashmir witnessed a catastrophic flood resulting in significant loss of lives and property. Such massive losses could have been avoided if any structural support such as dams were constructed the Jhelum basin, which has history devastating floods. The GIS-based multicriteria analysis (MCA) model provided three suitability zones for dam locations. final suitable sites identified within highest zone based on topography (cross-sections), stream order, high zone, minimum site...
