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. Such information is crucial in informing regulatory bodies and policymakers of the pollutant occurrence, guiding future research, and formulating ","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"18 ","pages":"Article 101094"},"PeriodicalIF":0.0,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143430181","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}

Rainfall variability poses significant challenges to rain-fed agriculture, which is the primary livelihood in the region. The study employs simple linear regression analyses to examine relationships between rainfall frequency and key food security indicators including crop yield, food quality, prices, variety, crop failure rates, and fodder yield. The findings reveal a robust positive relationship between increased rainfall frequency and enhanced food security outcomes. Specifically, higher rainfall frequency correlates statistically significantly with increased crop yields (β = 0.892, <em>p</em> &lt; .01), improved food quality (β = 0.777, <em>p</em> &lt; .01), stable food prices (β = 1.003, <em>p</em> &lt; .01), greater food variety (β = 0.831, <em>p</em> &lt; .01), reduced crop failures (β = 0.881, <em>p</em> &lt; .01), and increased fodder yield (β = 0.942, <em>p</em> &lt; .01). These relationships underscore the critical role of consistent rainfall patterns in sustaining agricultural productivity and market stability. The study concludes that maintaining reliable rainfall patterns is crucial for mitigating agricultural risks and promoting food security in rain-fed farms like the Qulujed district. Effective climate adaptation and water management strategies are essential to ensure sustainable agricultural production and resilience against climate variability. Understanding the impact of rainfall frequency on food security variables is imperative for achieving long-term development goals and supporting global efforts to combat food insecurity amid environmental change.</div></div>","PeriodicalId":34794,"journal":{"name":"Environmental Challenges","volume":"18 ","pages":"Article 101095"},"PeriodicalIF":0.0,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094548","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}

However, the recovery of this waste heat is not common. Therefore, this study presents a time series analysis to evaluate the potential for waste heat recovery for sustainable hotel operations. The case study focuses on a prototype hotel in subtropical Hong Kong and its engineering systems are modeled using EnergyPlus. By incorporating heat exchangers and thermal storage systems, waste condenser heat can be recovered to fully meet the heating demand for daily service water, which was originally supplied by boilers for 79.32 % of the total time. This application offers several benefits. Firstly, it reduces annual carbon emissions by 40.23 kgCO₂e/m² (equal to 27.36 % of the baseline emissions) associated with water-cooled chiller systems by maximizing energy efficiency and minimizing waste heat. Secondly, it decreases the operating capacity of cooling towers at high heat rejection, which reduces the chance of plume emissions by 30.9 %. Finally, it lowers the annual gas consumption of boilers by 153.11 MJ/m² (equal to 79.32 % of the baseline consumption) and can serve as an alternative to renewable solar thermal systems. Challenges and opportunities for recovering waste condenser heat are also discussed in detail. Notably, this study introduces a new approach of using outdoor enthalpy to normalize the cooling demand for improved energy management.
