Drought, a climate-related disaster impacting variety of sectors, poses challenges for millions people in South Asia. Accurate and complete drought information with proper monitoring system is very important revealing the complex nature its associated factors. In this regard, deep learning promising approach delineating non-linear characteristics Therefore, study aims to monitor by employing remote sensing data over Asia from 2001–2016. We considered precipitation, vegetation, soil factors...
Urbanization is an increasing phenomenon around the world, causing many adverse effects in urban areas. Urban heat island are of most well-known phenomena. In present study, surface islands (SUHI) were studied for seven megacities South Asian countries from 2000–2019. The thermal environment and relationship between land temperature (LST), use landcover (LULC) vegetation examined. connection was explored with remote-sensing indices such as field variance (UTFVI), intensity (SUHII) normal...
Landslide susceptibility assessment along the Araniko highway was done using relationship between landslide causative factor and presence/absence of linear discriminant analysis, divided into Low, Medium, High, Very High zone. The spatial analysis distribution with its conditioning factors depicts 40°-60° slope, South-east South direction aspect, 0–5 km North from MCT, 10–20 distance epicentre, where barren land forest area are found most susceptible to a landslide. This research can help...
Basin geomorphology is a complete system of landforms and topographic features that play crucial role in the basin-scale flood risk evaluation. Nepal country characterized by several rivers under influence frequent floods. Therefore, identifying areas paramount importance. The East Rapti River, tributary Ganga one flood-affected basins, where two major cities are located, making it to assess mitigate this river basin. A morphometric calculation was made based on Shuttle Radar Topographic...
Drought has devastating impacts on agriculture and other ecosystems, its occurrence is expected to increase in the future. However, spatiotemporal net primary productivity (NPP) Mongolia have remained uncertain. Hence, this paper focuses impact of drought NPP Mongolia. The events during 2003–2018 were identified using Moderate Resolution Imaging Spectroradiometer (MODIS) normalized difference vegetation index (NDVI). Boreal Ecosystem Productivity Simulator (BEPS)-derived was computed assess...
Drought is a very complex natural hazard and has negative impact on the global ecosystem as whole. Recently Bangladesh been experiencing by different degree of dryness consequence high climate variability, affecting crop production to great extent in last couple decades. In this context, present study was made an effort assess analyse drought characteristics based two indices, i.e., Standardized Precipitation Index (SPI) Vegetation Condition (VCI), model agricultural risk with...
Monsoon floods are frequent in the Tarai region of Nepal and claim thousands lives substantial numbers properties every year. Certain human activities more affected than others case same hazard. This study analyzes vulnerability to flooding among Tharu households. Data were collected by employing household surveys, group discussions, key informant interviews Thapapur Village Development Committee (VDC) Kailali district, western Tarai, Nepal. The analysis presented this is based on theory...
Heat-health risk is a growing concern in many regions of China due to the more frequent occurrence extremely hot weather. Spatial indexes based on various heat assessment frameworks can be used for risks. In this study, we adopted two approaches—Crichton’s triangle and vulnerability index (HVI) identify heat-health risks Northern Jiangxi Province China, by using remote sensing socio-economic data. The Geographical Information System (GIS) overlay principal component analysis (PCA) were...
The Himalayan region, a major source of fresh water, is recognized as water tower the world. Many perennial rivers originate from Nepal Himalaya, located in central part region. Snowmelt essential freshwater for living, whereas it poses flood disaster potential, which challenge sustainable development. Climate change also largely affects snowmelt hydrology. Therefore, river discharge measurement requires crucial attention face climate change, particularly runoff model (SRM) frequently used...
This article attempts to practicalise Open Science (OS) promote ideas and enhance efforts for the Sustainable Development Goals (SDGs). It delineates General Statements (n = 20) as guiding beacons Specific 70) that act precision tools in OS orientated policymaking, research, innovations, public engagement, access scientific knowledge. The authors hope draw kindled educated attention besides underscoring need unbiased, inclusive, diligent execution of SDGs. By adopting these accordingly...
Global warming threatens ecosystem functions, biodiversity, and rangeland productivity in Mongolia. The study analyzes the spatial temporal distributions of Net Primary Production (NPP) its response to climatic parameters. also highlights how various land cover types respond fluctuations from 2003 2018. Boreal Ecosystem Productivity Simulator (BEPS) model was used simulate NPP last 16 years. Satellite remote sensing data products were mainly as input for model, where ground-based MODIS...
Understanding the response of terrestrial ecosystems to future climate changes would substantially contribute scientific assessment vegetation–climate interactions. Here, spatiotemporal distribution and dynamics vegetation in China were projected compared based on comprehensive sequential classification system (CSCS) model under representative concentration pathway (RCP) RCP2.6, RCP4.5, RCP8.5 scenarios, five sensitivity levels proposed. The results show that CSCS performs well simulating...
Climate change poses significant challenges to tourism-dependent communities in mountain regions, threatening their livelihoods and well-being. However, there is a lack of comprehensive assessments that consider the multidimensional nature vulnerability specific socio-cultural contexts these communities. This study assesses livelihood Lamtang National Park exposed climate using Livelihood Vulnerability Index (LVI) -Intergovernmental Panel on Change (LVI-IPCC) framework. A mixed-methods...
Lakes are crucial for their multi-faceted services, including drinking water, irrigation, tourism, and more. Understanding status, area coverage, is important, continuous monitoring essential. can be monitored through various approaches, ranging from traditional ground-based surveys to advanced earth observation satellites. This study aimed monitor several lakes in Ward Number 26 of Pokhara Metropolitan City, Khaste, Neurini, Gunde Lakes, using high-resolution cadastral maps, field surveys,...
Land use and land cover (LULC) represents the physical component of Earth's environment, often changes as a result natural anthropogenic activities. This study carried out changing patterns orientations LULC types Bagmati province Nepal by using satellite images between 1996 2016. The applied classification scheme through support vector machines (SVM) for period from to 2006, 2006 Our explored that built-up area expansion was major change witnessed which increased 85.25 km2 in sharply...
The escalating global demand for energy has triggered a shift towards cleaner alternatives due to mounting environmental concerns. Emerging as viable substitute, solar power gained prominence fossil fuels' adverse impact becomes evident. Historically reliant on hydropower, Nepal is exploring alternative sources mitigate seasonal output variations. Despite abundant renewable resources like biomass, wind, and energy, Nepal's sector faces funding technical expertise challenges. Solar presents...
The government of Nepal has been implementing policies to increase agriculture production by motivating farmers towards farming. This study aims identify spatially distributed suitable areas for sustainable Arabica coffee in the Gulmi, Palpa, Arghakhanchi, and Pyuthan districts Lumbini Province. multi-criteria analysis was carried out area cultivation area, where parameter values were assigned based on Analytical Hierarchy Process (AHP).
