The most recent Global Slavery Index estimates that there are 40.3 million people enslaved globally. UN’s Agenda 2030 for Sustainable Development Goal number 8, section 8.7 specifically refers to the issue of forced labour: ending modern slavery and human trafficking, including child labour, in all forms by 2025. Although is a global political commitment slavery, one biggest barriers doing so having reliable timely, spatially explicit scalable data on activity. lack these compromises...

The capacity of aquifers to store water and the stability infrastructure can each be adversely influenced by variations in groundwater levels subsequent land subsidence. Along south bank River Thames, Battersea neighbourhood London is renovating a vast 42-acre (over 8 million sq ft) former industrial brownfield site become host community homes, shops, bars, restaurants, cafes, offices, over 19 acres public space. For this renovation, between 2016 2020, significant number bearing piles secant...

Satellite Earth Observation (EO) is often used as a cost-effective method to report on the condition of remote and inaccessible peatland areas. Current EO techniques are primarily limited reporting vegetation classes properties immediate peat surface using optical data, which can be infer condition. Another useful indicator that motion, has potential mass accumulation loss peat. Interferometic SAR (InSAR) provide this data from space. However, most common InSAR for information extraction,...

In this paper, we investigate land motion and groundwater level change phenomena using differential interferometric synthetic aperture radar (DInSAR) over the Northumberland Durham coalfield in United Kingdom. The study re-visits earlier research that applied a persistent scatterers interferometry (PSI) technique to ERS (European Remote Sensing) ENVISAT (Environmental Satellite) data. Here, Intermittent Small Baseline Subset (ISBAS) DInSAR is ERS, Sentinel-1 SAR datasets covering late 1990s,...

This work assesses the feasibility of national ground deformation monitoring Great Britain using synthetic aperture radar (SAR) imagery acquired by Copernicus’ Sentinel-1 constellation and interferometric SAR (InSAR) analyses. As December 2016, assessment reveals that, since May 2015, more than 250 wide (IW) swath products have been on average every month at regular revisit cycles for entirety Britain. A simulation distortions (layover, foreshortening, shadow) confirms that topographic...

Abstract Peatland surface motion is a key property of peatland that relates to condition. However, field‐based techniques measure are not cost‐effective over large areas and long time periods. An alternative method can quantify interferometric synthetic aperture radar. Although field validation the accuracy this difficult, value radar (InSAR) as means quantifying peat condition be tested. To achieve this, characteristics InSAR series measured an18‐month period at 22 sites in Flow Country...

From approximately 400 glaciers of the western Antarctic Peninsula, no in situ records mass balance exist and their recent contribution to sea level is consequently poorly constrained. We seek address this shortcoming by using surface elevations from USGS BAS airborne (1948–2005) ASTER spaceborne (2001–2010) stereo imagery, combined a rigorous semi‐automated registration approach, determine multi‐decadal glacier elevation changes Peninsula for 12 glaciers. All observed show near‐frontal...

Groundwater-induced land movement can cause damage to property and resources, thus its monitoring is very important for the safety economics of a city. London heavily built-up urban area relies largely on groundwater resource poses threat subsidence. Interferometric Synthetic Aperture Radar (InSAR) facilitate Gravity Recovery Climate Experiment (GRACE) gravity anomalies monitoring. For London, no previous study has investigated variations related using InSAR GRACE together. In this paper, we...

Groundwater variation can cause land-surface movement, which in turn significant and recurrent harm to infrastructure the water storage capacity of aquifers. The capital cities England (London) India (Delhi) are witnessing an ever-increasing population that has resulted excess pressure on groundwater resources. Thus, monitoring groundwater-induced land movement both these is very important terms understanding risk posed assets. Here, Sentinel-1 C-band radar images persistent scatterer...

Underground coal mining activities and ground movement are directly correlated, mining-induced can cause damage to property resources, thus its monitoring is essential for the safety economics of a city. Fangezhuang mine one largest coalfields in operation Tangshan, China. The enormous amount extraction has resulted significant over years. These phenomena have produced severe damages local infrastructure. This paper uses finite difference method (FDM) 3D model stacking interferometric...

Determining water occurrence in pore-fracture systems under specific saturation is of great significance to reveal the correlation between content and porosity/permeability coal reservoirs. In this work, simulation experiments intrusion drainage are used study micro-occurrence migration using NMR T2 T1–T2 techniques discuss influence system structure parameters on micro-occurrence. Meanwhile, distribution heterogeneity clarified by single- multifractal theories. The results show that (1)...

Peatland surface motion is highly diagnostic of peatland condition. Interferometric Synthetic Aperture Radar (InSAR) can measure this at the landscape scale but requires ground validation. This necessitates upscaling from point to areal measures (80 × 90 m) hampered by a lack data regarding spatial variability peat characteristics. Using nested precise leveling approach within two areas upland and low-lying blanket Flow Country, Scotland, we examine multiscale motion. We then compare with...

Abstract This study investigates land use, cover (LULC) changes, vegetation health, and drought severity in Rajasthan, India, from 1985 to 2020 using remote sensing techniques. By analyzing satellite imagery with the normalized difference index (NDVI), temperature condition (TCI), (VCI), NDVI deviation (Dev_NDVI), we assess spatial temporal dynamics of region's landscape conditions. Our findings indicate significant LULC including a decrease water bodies 6412.87 2248.51 km 2 dense forests by...
