Soil organic carbon (SOC) is essential for maintaining ecosystem health, and its depletion widely recognized as a key indicator of soil degradation. Activities such mining wildfire disturbances significantly intensify degradation, leading to quantitative qualitative declines in SOC. Accurate SOC monitoring critical, yet traditional methods are often costly time-intensive. Advances technologies like Unmanned Aerial Vehicles (UAVs) satellite remote sensing (SRS) now offer efficient scalable...
Abstract Wildfires have a significant impact on Soil Organic Carbon (SOC) content and fractionation. Here we used Diffuse Reflectance Spectroscopy (DRS) Machine Learning (ML) algorithms, particularly decision tree-based ones, to assess post-wildfire changes in labile, removable, recalcitrant SOC fractions across six distinct areas with varying wildfire recurrence levels. Once spectral data had been acquired by DRS, the transformation of raw through first second derivatives enhanced...
Phytoremediation is a cost-effective nature-based solution for brownfield reclamation. The choice of phytoextraction or phytostabilization strategies highly relevant when planning full-scale treatments. A suitable approach to identify such species involves the evaluation plants that grow spontaneously on contaminated sites. Here, we sought determine phytoremediation potential three spontaneous plant species, namely trees Acer pseudoplatanus L (A. pseudoplatanus) and Betula celtiberica Rothm....
Abstract Mining is a cornerstone of the productive system, particularly in sectors, such as renewable energy and electronic equipment production, where its significance anticipated to grow coming years. Aligned with principles Nature-Based Solutions Zero Waste policies, recycling mining waste soil amendments could concurrently restore degraded areas reduce disposal waste. In this context, we aimed remediate post-mining primarily impacted by heavy metal pollution using an alkaline generated...
In the context of soil pollution, plants suffer stress when exposed to extreme concentrations potentially toxic elements (PTEs). The alterations caused by such stressors can be monitored multispectral imagery in form vegetation indices, which inform pollution management strategies. Here we combined geochemistry and remote sensing techniques offer a preliminary assessment vast abandoned spoil heap surroundings La Soterraña mining site (Asturias, Spain). To study distribution PTEs over time,...
Traditional methods to acquire (geo)chemical data of Soil Organic Carbon (SOC) in soil rely on manual sampling, time-consuming and laborious chemical analyses, subsequent mapping by geostatistical interpolation methods. In this study, we propose the use UAV-RS Sentinel-2 images, still partially supported field for assessing different fractions SOC using a regression study through Machine Learning (ML) techniques. This approach is exemplified postmining degraded soils vast former coal-mining...
Hydrothermal carbonization (HTC) at temperatures of 150-250°C and self-generated pressures 1−5 MPa is an efficient technology to convert wet biomass wastes into stable carbon-rich solids (hydrochars) with great potential for energy production/storage, soil amendment, sustainable construction, adsorption, catalysis, etc., within a circular economy framework. The different composition the residues, impact operating conditions diversity reactions that take place during HTC...
