Large-scale of wetlands have been transformed into agriculture and urban region in response to human demands and requirements. Accurate mapping and monitoring of large-scale wetlands are of high importance but also challenging. The growing availability of large volumes of open-access satellite data and development of advanced machine-learning algorithms has been providing new opportunities for mapping and monitoring earth system and environment. Google Earth Engine (GEE)- a cloud-based computing platform, has been effectively applied in various areas of mapping ranging from forestry, agriculture, hydrological studies. This study uses high spatial resolution satellite data from Sentinel-1, Sentinel-2 and terrain indices for mapping and monitoring of wetlands of Pokhara Metropolitan city of central Nepal. We implemented different types of wetland classification models on the GEE platform using th...

An understanding of tree species and forest structural pattern variations across different climatic regions is crucial for mountain ecology. This study strived to carry out a comparative evaluation of species diversity, main stand variables, and canopy cover of forests with contrasting precipitation conditions in the Annapurna range. Firstly, climate data provided by CHELSA version 1.2, were used to identify distinct precipitation regimes. Lamjung and Mustang were selected as two contrasting precipitation regions, and have average annual precipitation of 2965 mm and 723 mm, respectively. Stratified random sampling was used to study 16 plots, each measuring 500 m2 and near the tree line at an elevation range of 3000 to 4000 m across different precipitation conditions. In total, 870 trees were identified and measured. Five hemispherical photos using a fisheye...
