  Abstract Mapping and monitoring of forest area suffering from deforestation and forest degradation using satellite images and remote sensing has been an achievable activity for the sustainable forest management and conservation. Mapping of disturbance and degradation of forest is gaining momentum through Remote Sensing despite, major challenges still exist. The present study was conducted to quantify the forest area of deforestation and degradation within the Maya Devi collaborative forest of Terai region located at Kapilvastu district of Nepal. This study based on the optical satellite data (Landsat 7 ETM of 2000 and Landsat 8 OLI/TIRS of 2016) and spectral un-mixing of these datasets which produced fractional cover (proportion of vegetation, non-photosynthetic vegetation and bare soil). Under the environment of CLASlite tools, mapping of damaged canopy, exposed soil and dead vegetation were produced. With the gap of 15 years two Landsat Image of 2000 and 2016 were p

  Abstract The demand for Critical Minerals (CMs) is soaring because of their extensive use in renewable energy generation, energy storage, energy transmission, scientific instrumentation, and a wide range of communication, military, and transport technologies. However, the supply of CMs faces several critical challenges like • a few countries have a monopoly in mining and processing of particular CMs • variable concentration and deposit grades in different geographical areas • inadequate assessment of resources • inefficient mining, extraction, and processing technologies, • little to no recycling • limited workforce and • severe environmental and human health impacts associated with CM mining, processing, and production. For environmentally sustainable development of the CM industry, countries need to make significant investments in advanced competitive research, development of efficient environment-friendly mining, extraction, and processing techno

  Graphical Abstract In the past decades evaporation of water has been generally decreasing in most parts of the world with increasing air temperature, which is called the ‘evaporation paradox’. At Tharandt, Germany from 2004 to 2013 on annual basis the so-called ‘evaporation paradox’ had not existed because air temperature had not shown increasing trend. However, when we exclude Class A pan evaporation (E p ) in to consideration, indeed, it had existed on the summer half-year (Figure 1). Highlights a) Consideration of the warmer times of a year in a cold climate site. b) Use of methods very suitable for a very humid climate. c) Consideration of both measured and estimated evaporation schemes.      Read More about this Article: https://juniperpublishers.com/ijesnr/IJESNR.MS.ID.556142.php Read More Juniper Publishers Google Scholar : https://scholar.google.com/citations?view_op=view_citation&hl=en&user=4WXzQFMAAAAJ&citation_for_view=4WXzQFMAAAAJ:
