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...
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...
Inland water plants, particularly those that thrive in shallow environments, are vital to the health of aquatic ecosystems. Water hyacinth is a typical example inland species, an invasive plant can drastically alter natural community’s floral diversity. The present study aims assess impact biomass on floristic characteristics plants Merbil wetland Brahmaputra floodplain, NE, India. Using systematic sampling technique, data were collected from field at regular intervals for one year (2021)...
Abstract Climate change and anthropogenic factors have exacerbated flood risks in many regions across the globe, including Himalayan foothill region India. The Jia Bharali River basin, situated this vulnerable area, frequently experiences high-magnitude floods, causing significant damage to environment local communities. Developing accurate reliable susceptibility models is crucial for effective prevention, management, adaptation strategies. In study, we aimed generate a comprehensive zone...
Abstract Floods represent a significant threat to human life, property, and agriculture, especially in low-lying floodplains. This study assesses flood susceptibility the Brahmaputra River basin, which spans China, India, Bhutan, Bangladesh—an area notorious for frequent flooding due saturation of river water intake capacity. We developed evaluated several innovative models predicting by employing Multi-Criteria Decision Making (MCDM) Machine Learning (ML) techniques. The showed robust...
Abstract In an era where global biodiversity hotspots are under unprecedented threat, understanding the intricate balance between land use cover (LULC) changes and their implications on ecosystem services value (ESV) becomes paramount. The region of Jammu Kashmir, with its distinctive ecological importance, is well known for these challenges opportunities. This embodies various conservation reserves national parks, one most ecologically rich called Kishtwar High Altitude National Park. It...
Disangmukh wetlands are an agglomeration of few beside the levee region River Brahmaputra where tributary Disang meets Mighty Brahmaputra. The present study examines physic-chemical properties water and sees relationship between quality aquatic macrophytes in wetland Assam. samples plants were collected from four sites namely Ronga Garh, Rongmon, Kaziranga Longsai beel. plantâs using quadrat sampling method with 1 square meter diversity has been calculated Shannon Diversity Index (SDI) (H...
