Integrated Management of the Urban Water Cycle: A Synthesis of Impacts and Solutions from Source to Tap
(MDPI, 2026-03-23) Marcoie, Nicolae; Iliesi, Elena; Barta, András-István; Raboșapca, Irina; Toma, Daniel; Boboc, Valentin; Balan, Cătălin-Dumitrel; Tofănică, Bogdan-Marian
Urbanization fundamentally fractures the natural water cycle, leading to a cascade of interconnected problems including increased flood risk, degraded water quality, stressed groundwater resources, and inefficient distribution networks. Traditional, fragmented management approaches that address these issues in isolation have proven inadequate. This research argues for a paradigm shift towards an Integrated Urban Water Management (IUWM) framework anchored in the concept of the “river-aquifer-pipe network continuum”, treating these components as a single, dynamic hydrological and infrastructural entity. Drawing upon a series of detailed case studies from Eastern Romania, this paper synthesizes the systemic impacts of development across the entire urban water system. Evidence from the Prut, Olt, and Bahlui river basins demonstrate how channelization exacerbates flood peaks and leads to severe biochemical degradation. Hydrogeological modeling of the Gherăești-Bacău wellfield reveals the vulnerabilities of over-extraction, while analysis of the Iași water network highlights the challenge of water losses in the aging infrastructure. In response, a modern, multi-tool approach is consolidated into a practical, three-stage framework for action: Diagnose, Prescribe, and Optimize. This framework advocates for (1) a comprehensive diagnosis using a suite of predictive numerical models (a “digital twin”); (2) the prescription of foundational, nature-based solutions, such as floodplain restoration, to heal core ecological functions; and (3) the continuous optimization of engineered infrastructure using smart, real-time control technologies. The synthesis concludes that an integrated, data-driven, and collaborative approach is the only sustainable path forward. Future research should focus on formally coupling these diagnostic models to create true Digital Twins of urban water systems—an essential step towards building resilient, water-secure cities for the 21st century.

Assessing Viticultural Parameters and Wine Quality in Relation to Climate Conditions
(MDPI, 2026-03-19) Scutarașu, Andrei; Colibaba, Lucia-Cintia; Scutarașu, Elena-Cristina; Luchian, Camelia-Elena; Rotaru, Liliana; Filimon, Răzvan Vasile; Filimon, Roxana Mihaela; Cotea, Valeriu V.
This study evaluates viticultural parameters of the Golia grape variety in relation to variable climatic conditions over the 2020–2024 period and analyzes their impact on wine quality. The data show significant climatic variability, with warming trends causing earlier flowering and ripening by 11–13 days. Grape production varied depending on climatic conditions, with 2021 and 2024 recording the highest number of shoots per trunk and increased fertility in 2024. Low winter temperature led to reduced bud viability and affected the overall health of the vines and harvest yields. Average annual precipitation, especially from the growing season, significantly influenced actual yield (AY), while higher annual temperatures and sunshine duration (Sun) resulted in lower grape weight. Greater sugar concentrations accumulated in years with higher temperatures, while higher acidity levels registered at lower temperatures. Higher precipitation (Pp) coupled with thermal accumulation promoted higher dry extract and alcoholic strength (AS), significantly enhancing the perception of honey notes (R2 > 0.7, p-value < 0.05). Furthermore, higher thermal regimes negatively impacted the expression of delicate aromatic compounds, diminishing specific notes such as rose and exotic fruits.

Phytobiotics as Dietary Natural Growth Promoters in Producing High-Quality and Safe Poultry Products—A Narrative Review
(MDPI, 2026-02-14) Cojocariu, Laurian-Cristian; Usturoi, Marius-Giorgi; Usturoi, Alexandru; Lazăr, Mircea; Balmuș, Ioana Miruna; Simeanu, Daniel; Radu-Rusu, Răzvan-Mihail
As the demand for poultry meat and eggs is increasing in the world, and the use of antibiotics is forbidden in Europe (since 2006), with countries such as the Philippines, Thailand, Bangladesh and China having imposed restriction or prohibitions, researchers and producers have sought for effective non-antibiotic alternatives. Probiotics, prebiotics, synbiotics and phytobiotics are frequently used as alternatives in the field of poultry production. Phytobiotics, plant-derived substances, also referred to as botanicals or phytogenics, are used as animal diets supplements due to their wide range of bioactive compounds (menthol, curcumin, eugenol, allicin and others) and many advantages. They are classified as herbs, spices, plant extracts and essential oils. Some of the benefits offered by the dietary phytobiotics are antimicrobial, antioxidant, digestion stimulant, anti-inflammatory, immunomodulatory, carminative, antiseptic and appetite stimulant, the modulation of gut microbiota and improvement in the intestinal histology. Some representatives of phytobiotics are turmeric, oregano, sage, thyme, black pepper, ginger, garlic, echinacea, rosemary and others. Despite the significant potential of phytobiotics, their widespread adaptation is currently inhibited by challenges regarding cost-effectiveness (high price for raw materials), scarce regulatory frameworks, and inconsistent biological efficacy. The lack of standardization reflects a dual challenge, enclosing both the inherent chemical variability of raw botanical materials and the technical inconsistencies present throughout the industrial manufacturing, and extraction processes as producers use different machinery for extracting and producing the animal feed. To address these systemic impediments, a joint effort across the entire value chain—from primary producers to regulatory authorities—is essential for the development of unified testing protocols and standardization dosage guidelines that ensure the pharmacological safety and reliability of phytobiotic products.

Design and characterization of sustainable mortars incorporating industrial waste–derived materials
(Nature Research, 2026-03-04) Caftanachi, Mihaela; Vrabie, Mihai; Harja, Maria; Bucur, Roxana-Dana; Bucur, Daniel
Environmental pressures necessitate finding alternatives to Portland cement using alkali-activated aluminosilicate materials. Mortars containing different types of class F fly ash (Romania and Canada), furnace slag, silica fume and sand, activated with 5.1 M potassium hydroxide solution and 40% sodium silicate solution. Three mixes were tested (Mix 1 – fly ash Romania, Mix 2 - fly ash Canada and Mix 3 – fly ash Canada and slag). The activators were chosen to develop materials with high mechanical strength. The activation process occurred at controlled laboratory conditions (20 ± 2℃ and 65% relative humidity). Mix 3 showed the highest strength values of 43.8 MPa and a flexural strength of 7.4 MPa after 28 days. Mix 2 had a compressive strength of 26.0 MPa, in contrast to 8.3 MPa for Mix 1. The addition of blast furnace slag (Mix 3 vs. Mix 2) nearly doubled the compressive strength values. Proposed mixes are an effective alternative to cement mortar that reduce waste, through valorization of industrial by-products and diminish carbon dioxide emissions by 30%. Microstructural analyses (SEM and XRD) confirmed the formation of reaction products consistent with the observed mechanical strength. The developed mixes show promising mechanical performance and contribute to reducing CO₂ emissions in construction materials.

Occurrence of Mineral Oil Hydrocarbons in Feed and Milk: Implications for Sustainable Dairy Production
(MDPI, 2026-03-16) Matei, Mădălina; Flocea, Elena-Iuliana; Pop, Ioan-Mircea
Mineral oil hydrocarbons (MOH) are increasingly reported in agri-food systems, but their presence in dairy production is not yet fully characterized. This study investigated the occurrence of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) in feed and milk collected from three dairy farms with different production conditions, with the aim of supporting a system-wide interpretation of contaminant presence. Samples were analyzed using confirmed chromatographic methods, and the results were descriptively evaluated to express variability both within and between farms. Both feed and milk samples showed heterogeneous contamination patterns, highlighting the influence of environmental exposure, technological activities and biological variations, rather than a direct linear transfer. To help the interpretation, a conceptual framework linking environment, feed, animals and milk was proposed. From a sustainability point of view, the results highlight the importance of preventive monitoring and farm-level management strategies to reduce contaminant pressure in dairy production. Overall, the study furnishes empirical evidence that contributes to a broader understanding of contaminant occurrence and supports integrated approaches for food safety and sustainable dairy production.
