These environmental changes include droughts, rising temperatures, soil erosion, and weed invasion. Prior research has explored the potential of biodegradable mulch to help address these challenges while also reducing microplastic pollution associated with plastic mulch. Despite numerous research efforts on biodegradable mulch, there is limited evidence on how environmental factors influence the effectiveness of biodegradable mulch across diverse sites. This study uses machine learning models to examine how biophysical environmental conditions relate to the agronomic impacts and degradation rates of biodegradable mulch. The results of Random Forest, Support Vector Machine, and Decision Tree models confirm that precipitation and temperature are relevant in predicting the effects of biodegradable mulches, with hot and arid climate conditions associated with positive mulch effects. Soil attributes, including texture, organic carbon, and pH levels, are also identified as key variables. Notably, Decision Tree models indicate that maintaining soil pH levels between 6.2–7.8 and ensuring minimum monthly temperatures exceed 3.4 °C are identified as benchmark values for achieving positive mulch effects on agronomic performance. Meanwhile, monthly precipitation above 78 mm is associated with high degradation rates that exceed regulatory standards and reduce the effectiveness of mulch application. Despite variations in overall accuracy, the Random Forest and Decision Tree models demonstrated robustness in their potential reliability in classifying mulch effect outcomes. These results serve as a useful guide to identifying potential suitable sites for biodegradable mulch application and suggest further product development is needed to meet the needs of diverse environmental contexts in efforts to scale up adoption.</div></div>","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"18 ","pages":"Article 101105"},"PeriodicalIF":0.0,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data from all 47 prefectures in Japan were analyzed from 2014 to 2019 and in 2023.

The model was implemented as a web-based platform for real-time risk assessments and to help emergency services and local governments manage medical resources effectively during heatwaves.

However, it is well-known that dumpsites contain mixed waste streams from diverse sources including households, electronics, industry, medical supplies, and beauty centres. The breakdown of such wastes generates pollutants such as industrial chemicals (microplastics, phthalate esters, polycyclic aromatic hydrocarbons, polychlorinated biphenyl, perfluorinated compounds, phenols), pharmaceuticals, and personal care products into the environment and eventually to the food chain. Many of these compounds are toxic, known endocrine disruptors and carcinogens, and can bioaccumulate in the food chain, posing ecological and human health risks. While these chemicals have been extensively studied across various environmental compartments, very few studies exist in the context of dumpsites, as food production areas. To address this knowledge gap, we conducted an in-depth literature review that selected 86 articles, published between 2000 and 2023, to explore the occurrence (presence and concentrations) of key emerging and persistent organic pollutants in dumpsite leachate, soils, and plants, at the global scale. Overall, our findings reveal a lack of standardization in waste management terminologies, with frequent confusion and interchangeable use of the terms: “dumpsites” and “landfills”. Furthermore among the relevant dumpsite studies, we found that most publications reported on microplastics (28), polyaromatic hydrocarbons (26), phthalate esters (23), polychlorinated biphenyls (21), and phenols (20). These studies also highlight significant variations in concentrations of pollutants and their measurement units, particularly for microplastics. Leachate (47) and soils (45) were the most studied matrices, while only five articles focussed on crops growing on dumpsites, limiting the overall global understanding of the dumpsite-food chain issue. Additionally, there was an imbalance in the geographical distribution of studies, with many of them conducted in Asia (49%), and Europe (30%), while fewer publications were cited from Africa (13%), North and South America (6%), and Australia (2%). Overall, our review addresses a broad spectrum of emerging pollutants, thus allowing a comprehensive evaluation of the range of chemical types and their respective concentrations in dumpsite ecosystems. Furthermore, this systematic and critical analysis helps to identify knowledge gaps related to the standardization of assessment and quantification protocols, pollutant pathways, fate and accumulation into environmental pools, as well as the potential resultant risks to the environment and human health.
