Lakes are vital freshwater ecosystems that sustain biodiversity, support livelihoods, and drive socio-economic growth globally. However, they face escalating threats from anthropogenic activities, including urbanization, agricultural runoff, pollution, which exacerbated by climate change. Phewa Lake in Nepal was selected for this study due to its increasing rates of nutrient enrichment, sedimentation, pollution. This evaluated seasonal spatial water quality variations within the lake...
Human activities and climate change increasingly threaten wetlands worldwide, yet their hydrochemical properties water quality are often inadequately studied. This research focused on the Ghodaghodi Lake Complex (GLC) associated lakes in Nepal, a Ramsar-listed site known for its biodiversity ecological significance. The study was conducted to assess seasonal quality, investigate factors influencing hydrochemistry, lakes’ suitability irrigation. Forty-nine samples were collected from GLC...
The academic sectors are badly affected by the COVID-19 pandemic globally. studies regarding implications of in education Nepal were minimal, thus, this paper aims to highlight impacts on sector Nepal. It is revealed that Nepalese academia has been facing problems due lack adequate and appropriate sustainable infrastructure for online system, including skilled human resources. In addition, limited internet facilities remote rural areas other challenging tasks virtual activities. Therefore,...
The Ramaroshan Lake Complex (RLC) in Sudurpaschim Province, Nepal, is a Himalayan lake cluster that holds significant ecological, economic, religious, and esthetic importance. This study aimed to provide comprehensive characterization of the hydrochemical properties water within RLC assess its suitability for irrigation purposes. A total 38 samples were collected from seven different lakes complex. physicochemical parameters major ions then analyzed. alkaline, based on hardness, they ranged...
Abstract The response of native plants to allelopathic interference invasive species may differ from species. In this study, the phytotoxic effects Ageratina adenophora were tested on two shrubs ( Osbeckia stellata and Elsholtzia blanda ) Nepal. Both grown in pots under treatments A. fresh leaves root leachates, litter. Then, seedling length biomass compared among treatments. results show that litter has stimulatory but leachates are growth development shrubs. Infrared Spectroscopy (IR)...
Water scarcity occurs in the agriculturally dominated Upper catchment area of Narmada River, Central India because overexploitation underground water for residential, industrial, and other uses. Delineating Ground Potential Zone (GWPZ) is critical to meeting area's demand. Finding River groundwater potential zone primary goal this study. The study uses geographical methodologies based on Analytical Hierarchical Process (AHP). To create a GWPZ map, ArcGIS 10.4 software compiles eight thematic...
Water is a prime natural resource and precious national asset one of the chief constituents environment. The chemical characteristics play key role in terms ecological economic perspectives river water. characterization evaluation water quality Karmanasha River necessary due to its immense importance livelihood people core urban areas Kathmandu valley, Nepal. In this study, surface samples were collected from 16 sites with 0.5 km interval characterize evaluate mainly perspective irrigational...
The exotic herbaceous plant <i>Tagetes minuta</i> L., native to South America, has been reported as a naturalized species in Nepal. is listed among the invasive due its threat natural communities many countries, including India and China (countries that neighbor Nepal). Plant characteristics such small, light, relatively numerous seeds, rapid seed germination, drought tolerance, potential harm neighboring plants are characters of this make it invasive. In Nepal, from different...
