This review systematically analyzes 58 peer-reviewed studies that utilize linear programming (LP) and its advanced variants to optimize agricultural water use, with a specific emphasis on improving water footprint (WF) efficiency. Applications are categorized into three core domains: crop allocation and land use, irrigation scheduling, and economic optimization. The findings reveal that while LP continues to dominate, alternative models-such as mixed-integer programming (MILP), weighted and fuzzy goal programming (WGP, FGP), and fractional programming-are gaining traction for their ability to address real-world complexities and multi-objective decision environments. However, critical gaps remain, particularly in the integration of WF indicators, climate variability, and socio-economic dynamics. This review not only maps the existing optimization landscape but also proposes a forward-looking research agenda. Key directions include the development of hybrid models, the explicit incorporation of WF metrics into objective functions, and the integration of decision-support systems for policy and farm-level planning. WF-aware optimization is thus positioned not merely as a technical instrument, but as a transformative tool for advancing agricultural sustainability-enhancing resilience, equity, and ecological stewardship in water-scarce regions and beyond.</p>","PeriodicalId":13557,"journal":{"name":"Integrated Environmental Assessment and Management","volume":" ","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145091488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An integrated geospatial-statistical approach was applied to 146 urban wards using Hotspot Analysis (Getis-Ord Gi*), Global and Local Moran's I, overlay analysis, and zonal statistics. Waste generation data were spatially linked with land use typologies and population density to detect statistically significant patterns. Daily waste generation ranged from 0.43 to 11.13 metric tons (t/day) across wards. High-intensity hotspots were found in densely populated and mixed-use zones, such as Ward 15 (0.61 kg/person/day) and Ward 5 (0.88 kg/person/day). Spatial autocorrelation analysis confirmed significant clustering (Global Moran's I = 0.056, z = 2.59, p = 0.009), with prominent hotspots identified in Wards 12, 13 (Kota-North) and Wards 16, 17 (Kota-South) at 99% confidence. Residential zones contributed the highest MSW load (541.97 t/day), followed by industrial (55.69 t/day) and commercial areas (50.20 t/day).

VTG, an egg-yolk precursor protein in oviparous species, is an informative marker of possible chemical-induced endocrine activity (particularly estrogenicity). Vitellogenin measurement is included in several standardised Test Guidelines published by the OECD and United States Environmental Protection Agency for the assessment of endocrine activity of chemicals in fish (and one in amphibians). However, in vivo VTG data across and within fish species can be highly variable and influenced by both technical and biological factors, affecting the reliability and interpretation of results. This poses a challenge for regulatory decision making and can trigger potentially unnecessary vertebrate studies or prevent necessary further investigations. The workshop brought together 42 experts from different sectors and geographies, to discuss three key aspects regarding VTG assessment: 1) technical/laboratory factors and VTG quantification; 2) data handling and statistics, and 3) interpreting the biological relevance of VTG responses. The workshop participants discussed the development and needs of a Guidance Document to provide harmonised recommendations, best practices, quality assurance criteria, and minimum reporting standards for VTG assessment in regulatory studies across the different test guidelines. Several areas were identified where further work and discussion are needed to inform on the development of the Guidance Document, such as the use of historical control data, the identification of potential outliers, the presentation of data, and analysis of case study examples. Provision of such a Guidance Document will further support the use of VTG as a relevant marker for a key aspect of endocrine activity assessment for regulatory decision making.

The methods were compared for their ability to (1) assess species richness and abundance, (2) detect and monitor invasive and dominant species, and (3) understand community composition. We assessed the biases of the compared methods, identified the training and skills needed to conduct sampling, and examined sampling costs in relation to total monitoring costs. Results show that smaller plots are able to detect more species per unit area sampled without significant differences in floristic quality measures. Data from smaller plots were sufficient for comprehensively describing site conditions even when less of the total site area was sampled. Although multivariate analyses of data from smaller plots yielded greater within-group dissimilarity than data from larger plots, multiple response permutation procedure analyses indicated no significant differences between nonmetric multidimensional scaling solutions based on data from the different sampling methods. Regardless of the sampling methods used to collect data, use of multivariate analyses identified a gradient of time since restoration was implemented as the dominant factor relating to differences between community composition.

Because HM bioaccessibility depends on local soil and geographic characteristics, identifying its relationship with soil properties is crucial for assessing soil pollution potential. Although HM concentrations can be measured relatively easily, bioaccessibility requires complex laboratory procedures, limiting routine applications in regulatory contexts. Integrating spatial information with bioaccessibility-based risk assessments can help identify pollution hotspots and better protect at-risk groups. This study developed a novel approach that spatially integrates HM bioaccessibility into health risk assessment. Using the simple bioaccessibility extraction test (SBET), farmland soils from 98 sites across Taiwan were analyzed to establish predictive equations for six common HMs: cadmium (Cd), lead (Pb), chromium (Cr), nickel (Ni), copper (Cu), and zinc (Zn). These equations were combined with previous soil survey data to generate spatial SBET maps across all agricultural regions in Taiwan. Results showed clear geographic variations: high Cd SBET (50%-100%) occurred in northern Taiwan with acidic soils, while elevated Cu and Zn SBET (45%-60%) were found in southern Taiwan with lower clay contents. We further applied the spatial SBET maps to Changhua County, a representative agricultural region. Infants and children exhibited higher non-carcinogenic risks (hazard index >0.01), especially in western villages, while adults had lower risks (<0.005). Seniors showed concerns of carcinogenic risks (total cancer risk index >1.0E-6).

Imidacloprid is commonly used in Afrotropical regions such as South Africa, yet limited information is available on its toxicity to aquatic ecosystems within this climate region. To address this, a 16-week outdoor microcosm study was conducted, exposing aquatic communities to 0.1, 10 and 250 µg/L imidacloprid under natural conditions. Physicochemical parameters, such as pH, dissolved oxygen, temperature, and various others, were monitored regularly. The microbial community, organic decomposition and zooplankton were largely unaffected by the exposure to imidacloprid. In contrast, 10 and 250 µg/L of imidacloprid led to long-term effects on the macroinvertebrate community, while short-term effects were found in the 0.1 µg/L treatment. Families such as Coenagrionidae were affected across all treatments, while Caenidae and Notonectidae were only affected in the highest treatment. Changes in the community structure resulted in reduced predator abundance (such as Coenagrionidae, Libellulidae and Notonectidae) and increased filter feeders (Culicidae). High temperatures likely increase the toxicity to arthropods when compared to similar studies with lower light intensities and temperatures. Recovery was limited during the post-exposure period, with some families (Baetidae) rebounding quickly, while others, Caenidae and Coenagrionidae, showed delayed recovery. Full recovery of the macroinvertebrate community systems did not occur during the 8-week recovery period, highlighting the importance of unexposed refuges for recolonization.

The data is parameterized using European Union data on waste water treatment plants, locations, infrastructure, and global spatial datasets on population and river flow rates and routing. The model provides substance concentration distributions based on spatial variability of these parameters across Europe while taking into account river connectivity, chemical routing between rivers, and in-stream decay. Chemical-specific model inputs include wastewater treatment removals, in-stream decay rates, and emissions. The model is demonstrated for four case study chemicals that are used in consumer products with down-the-drain disposal routes: linear alkylbenzene sulfonate and alkyl sulfate are common surfactants used in laundry detergents, and oxybenzone and octinoxate are UV-filters used in personal care products. Monitoring data were collected to represent spatial variability across Europe as a comparison to modeled values. Modeled concentrations were found to be predictive while still being conservative, with 90th percentile modeled concentrations agreeing with monitored concentrations within a factor of 2-8 across the case study substances.
