Climate change and landscape transformation have led to rapid expansion of peri-urban areas globally, representing new 'laboratories' for the study human-nature relationships aiming at land degradation management. This paper contributes debate on human-driven processes by highlighting how natural socioeconomic forces trigger soil depletion environmental in areas. The aim was classify synthesise interactions urbanisation-driven factors with direct or indirect, on-site off-site, short-term century-scale impacts degradation, focussing Southern Europe as a paradigmatic case address this issue. Assuming complex multifaceted among influencing factors, relevant contribution shown derive from drivers, most important which were population growth urban sprawl. Viewing socio-environmental systems adapting intense transformations, these identified forming 'syndromes' driven urbanisation.

Tuning mono-divalent cation water composition by the capacitive ion-exchange mechanism

Water Research, Journal Year: 2024, Volume and Issue: 255, P. 121469 - 121469

Published: March 13, 2024

Soil salinization poses a significant challenge to agricultural activities. To address this, the industry seeks an irrigation water solution that reduces both ionic conductivity and sodium adsorption rate (SAR), thereby diminishing risks of soil sodification fostering sustainable crop production. Capacitive deionization (CDI) is attractive electrochemical technology advance this search. Recently, one-dimensional transient CDI model unveiled capacitive ion-exchange mechanism presenting potential adjust treated composition by modifying monovalent divalent cation concentrations, influencing SAR index. This behavior would be achieved using electrodes rich in surface functional groups able efficiently capture cations during conditioning releasing them charging while capturing ions. Beyond theoretical modelling, current experimental research demonstrates, for first time, effectiveness pilot plant real samples spiked with solutions containing specific mono Electrosorption experiments computational modeling, specifically Density-Functional Theory (DFT), were used along analysis present describe phenomenon validate steps involved on it, highlighting as critical step.

In regions where drought has become a common occurrence for most of the year and agriculture is main economic activity, development hydro-agricultural systems made it possible to improve water management. Despite this, intensification combined with climate change leads potential decrease in quality management practices are essential agro-environmental sustainability. The aim this study was assess irrigation ecological status reservoir (using support chemical parameters). results showed biological oxygen demand values above maximum stipulated an excellent all sampling periods except April 2018 December 2020 (with highest 10 mg L−1 O2 dry periods). Most total nitrogen concentrations (TN) surpassed those good (0.96 ≤ TN 2.44 N). fact, suspended solids were parameters used classification. From perspective according FAO guidelines regarding infiltration rate, these waters presented light moderate levels restrictions.

The Alqueva reservoir is essential for water supply in the Alentejo region (south of Portugal). Satellite data are to overcome temporal and spatial limitations situ measurements, ensuring continuous global quality monitoring. Data between 2017 2020, obtained from OLCI (Ocean Land Color Instrument) aboard Sentinel-3, were explored. Two different methods used assess reservoir: K-means group reflectance spectra into optical types (OWT), empirical algorithms estimate parameters. Spatial (in five areas reservoir) (monthly) variations OWT parameters analyzed, namely, Secchi depth, turbidity, chlorophyll a, phycocyanin concentrations. One cluster has been identified representing typical presence microalgae reservoir, mainly July October more intense northern reservoir. An type area with highest transparency lowest a concentration was defined. methodology proposed suitable continuously monitor constituting useful contribution potential early warning system identification critical corresponding cyanobacterial algae blooms.

Abstract The salt-affected soils national map of Greece was recently made available within the initiative Global Soil Partnership (GSP) Food and Agriculture Organization United Nations FAO. present study explores development higher resolution soil property maps included in this scale product adopting a modified version FAO methodology logistic regression (LR) method based on ground satellite data. Furthermore, it also investigates correlation between saline organic carbon (SOC) using geospatial analysis methods. island Lesvos has been selected as case study. A probabilistic model for agricultural land is produced by exploiting geoinformation technologies. As result, spatial distribution croplands obtained. Indicatively, areas with p > 0.80 occurrence accounting ∼20% total area 169.51 km 2 Lesvos. Nagelkerke R coefficient showed that interprets 11.3% variance dependent variable from independent factors. accuracy assessed receiver operating characteristic (ROC) curve, which reasonable adaptability under curve (equal to 0.73). methodological approach proposed herein can support decision-making protection planning activities are key priority today due environmental instability, food security, climate change.

Published: Oct. 12, 2022

Increase in soil salinity, driven by climate change, is a widespread constrain for viticulture across several regions, including the Mediterranean basin. The implementation of salt-tolerant varieties sought after to reduce negative impact salinity grape production. An accession wild grapevine (Vitis vinifera L. ssp. sylvestris), named AS1B, found on coastline Asturias (Spain), could be interest toward achievement varieties, as it demonstrated ability survive and grow under high levels salinity. In present study, AS1B compared against widely cultivated commercial rootstock Richter 110, regarding their survival capabilities, transcriptomic profiles analysis allowed us identify genes employing RNA-seq gene ontology analyses increasing validate (via RT-qPCR) seven salinity-stress-induced genes. results suggest contrasting responses between 110. more responsive milder increase builds up specific mechanisms tolerance over sustained salt stress, while 110 maintains constitutive expression until prolonged saline inputs, when mainly shows osmotic stress. genetic basis AS1B's strategy confront valuable cultivar breeding programs, expand current range rootstocks, aiming improve adaptation change.
