Five different multi-temporal data sets years 2007, 2008, 2010, 2015, 2018 were LULC mapping, followed by maximum likelihood supervised classification technique. The...

Over the past two decades, eco-engineering has been recognized as an important restoration approach to promote vegetation regrowth and greenness in a widespread rocky desertification land of southwest China. However, it remains unclear recovery patterns dominating drivers different types karst landforms. Here we use multi-satellite archives based on Google Earth Engine (GEE) reveal rapid greening process although encountered severe drought, especially Karst Peak-Cluster Depression...

Planning and urban sustainability depend equally on understanding land use cover (LULC) change, variability, landscape risk (LR) assessment in earthquake-prone areas. This paper considered Barkal town its environs (BTEN), an area close to the 2003 Barkal-Rangamati Earthquake (5.7 Mw) for LR change analysis from 2001–2024. Six different multi-temporal data years 2001, 2003, 2011, 2021, 2024 are used detailed assess spatial temporal LULC changes. Further, mapping, Geographical Information...

Overdependence on and exploitation of forest resources have significantly transformed the natural reserve Sundarban, which shares largest mangrove territory in world, into a great degradation status. By observing these, most pressing concern is how much occurred past, what will be scenarios future if they continue? To confirm status past decades reveal trend, we took Sundarban Reserve Forest (SRF) as an example, used satellite Earth observation historical Landsat imagery between 1989 2019...

The global and regional land use/cover changes (LUCCs) are experiencing widespread changes, particularly in Baghdad City, the oldest city of Iraq, where it lacks ecological restoration environmental management actions at present. To date, multiple uses urban construction-related expansion, population increase, socioeconomic development. Comprehensive evaluation understanding effect sprawl its rapid LUCC great importance to managing surface resources for sustainable present research applied...

Due to inappropriate management and absence of land use planning, cover change developing country like Bangladesh is a common phenomenon. This phenomenon will have its tremendous effect if found at greater extent on natural habitat area for numerous animal tree species. In this study, Chunati Wildlife Sanctuary (CWS) was assessed from (2005-2015) using Landsat TM (Thematic Mapper) 8 OLI/TIRS (Operational Land Imager/Thermal Infrared Sensor). ArcGIS v10.1 ERDAS Imagine v14 were used process...

Understanding future landscape risk pattern change (FLRPC) scenarios will help people manage and utilize natural resources. In this study, we have selected a variety of anthropogenic factors as parameters for FLRPC assessment. Land use/cover (LUCC) land surface temperature (LST) are regarded significant that resulted in large-scale environmental changes. Result analysis the previous LUCC from 1985 to 2020 showed construction water body (WB) increased by 669.09 183.16 km2, respectively. The...

Bandarban Hill Tracts is facing grave environmental problems with fast depletion of its natural resources which ultimately threatening the existence forest cover. Monitoring change cover using multi temporal Landsat TM data (i.e. 1989, 2001 and 2010) for Part exact evaluation anthropogenic intervention on environment can be assessed. Present research focusing along middle course Matamuhuri River’s adjoining areas. The Normalized Difference Vegetation Index (NDVI) technique was applied to...

Forest is one of the most important surface coverage types. Monitoring its dynamics great significance in global ecological environment monitoring and carbon circulation research. based on Landsat time-series stacks a research hotspot, continuous change detection novel approach to real-time detection. Here, we present an approach, classification-spectral trajectory breakpoint recognition, running Google Earth Engine (GEE) for forest disturbance long-term trends. We used this monitor cover...

The Palghar region (north Maharashtra, India), located in the northwestern part of stable continental India, experienced a low magnitude earthquake swarm, which was initiated September 2018 and is continuing to date (as October 2021). From December 2020, ~5000 earthquakes with magnitudes from M1.2 M3.8 occurred small 20 × 10 km2. These were probably triggered by fluid migration during seasonal rainfall. In this study, we have used multi-temporal Landsat satellite data year 2000, 2015, 2018,...
