The article describes a preparation method and performance behavior of polymer composite systems with a matrix of low-density polyethylene (LDPE) and a reinforcing agent of Taurit. Taurit (a kind of shungite) is an inexpensive, well-available, and environmentally friendly mineral that is compatible with many polymers. The composites have been prepared via extrusion blending, and their mechanical and protective properties have been studied. The performance of Taurit-containing materials has been compared with properties of composites with other commonly used fillers (e.g., carbon black, talc, aluminum oxide, and asbestos fibers), and Taurit has proved to be the most efficient reinforcement in this series. The results indicate that the obtained composites can be used as coatings of pipelines to protect them from corrosion and mechanical damage.

Industrial emissions and legacy contamination from metallurgical activities can constrain sustainable land use by degrading soil quality and limiting vegetation establishment. This study combines a site-based contamination assessment with an early-stage plant tolerance screening to inform nature-based restoration planning in Central Kazakhstan. Soils were collected around three metallurgical complexes and analysed for heavy metals; exceedance relative to maximum permissible concentrations (MPC) was used to prioritise contaminants of concern. Seven locally occurring plant species were then screened in controlled Petri-dish assays using metal salt solutions (Pb, Zn, Cu, Cr, Cd and Ni), and germination percentage, germination dynamics, seedling shoot length and a growth inhibition index were quantified. Soil results showed elevated metal loads with frequent MPC exceedance, supporting the selection of these metals for biological screening. Plant responses were strongly species-specific: Brassica juncea and Medicago sativa maintained comparatively higher germination and early growth across treatments, whereas Suaeda salsa, Artemisia absinthium and Trifolium repens exhibited very low germination. These findings provide an evidence-based shortlist of candidate species for subsequent soil-based trials (including uptake and stabilisation assessment) and support risk-informed revegetation strategies for contaminated industrial landscapes.

Floodplains sustain fisheries, water supply, and climate regulation, and their services depend on the water regime—the extent, depth, frequency, duration, and connectivity of inundation—which dams, drought, and land-use change are altering. Remote sensing and GIS can supply evidence for managing these systems sustainably, yet the methods remain dispersed, and their fit to management needs has not been assessed. Following the PRISMA Extension for Scoping Reviews (PRISMA-ScR) and a publicly posted protocol, we retrieved peer-reviewed studies from Dimensions and OpenAlex (2004–2026), searched on 13 July 2026 and updated on 14 August 2026, and screened them in two stages with two reviewers. We charted data by study area, sensors, methods, variables, and drivers, then mapped them onto the decisions and Sustainable Development Goal targets they inform. Of 137 studies, 53% appeared since 2021; 2026 is only partially covered. Inundation extent dominates (83%), mapped mainly with Landsat (36%) and radar, whereas water level (28%), connectivity (21%), inundation frequency (14%), storage (13%), hydroperiod (12%), and depth (8%) remain scarce, as does evidence from data-scarce transboundary basins, including Central Asia. The attributes most needed for environmental-flow, allocation, and restoration decisions thus appear to be the least observed—a decision–observation mismatch that shapes monitoring priorities.

Floodplains sustain fisheries, water supply, and climate regulation, and the services they deliver depend on the water regime — the extent, depth, frequency, duration, and connectivity of inundation — which dams, drought, and land-use change are altering. Remote sensing (RS) and Geographic Information Systems (GIS) can supply the evidence needed to manage these systems sustainably, yet the methods remain dispersed and their fit to management needs has not been assessed. Following the PRISMA-ScR framework and a publicly posted protocol, peer-reviewed studies were retrieved from two databases (Dimensions and OpenAlex, 2004–2026) and screened in two stages by two independent reviewers; data were charted on study area, sensors, methods, water-regime variables, and drivers, and the variables were then mapped onto the decisions and Sustainable Development Goal targets they inform. Of 132 studies, 52% appeared since 2021. Inundation extent dominates (54%), mapped mainly with Landsat (36%) and radar, whereas water level (28%), connectivity (20%), hydroperiod (16%), storage (14%), and depth (8%) remain scarce, as does evidence from data-scarce and transboundary basins such as those of Central Asia. The attributes most needed for environmental-flow, allocation, and restoration decisions are thus the least observed — a decision–observation mismatch that sets the priorities for floodplain monitoring.
