Special Issue Information

Dear Colleagues,

In this Special Issue, we aim to feature early-career researchers in Earth Science. The leading author(s) of each contribution should be (a) the first or last author as well as the corresponding author and (b) be within 10 years of completing their Ph.D. (or equivalent) or becoming an assistant professor/on track to make tenure. Contributions are welcome from any discipline that advances understanding of the interactions connecting global environmental systems. Core themes include—but are not limited to—air-quality and atmospheric change, climate-change impacts on water and soil resources, land-use/land-cover feedbacks (agriculture, forestry), biodiversity and ecosystem dynamics under global change, resource management and conservation, natural and anthropogenic hazards, food–security–environment nexuses, and urban-environment-health interactions. Studies that integrate in situ monitoring, remote sensing, laboratory experiments, theory, or computational modeling are encouraged; manuscripts may be experimental, observational, or conceptual.

Articles submitted for this Special Issue should meet all the standard requirements of individual Earth articles (regarding quality, novelty, and significance) and be relevant to a broad international and interdisciplinary readership. 

Prof. Dr. Charles Jones
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Earth is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This study estimated the relative risks (RRs) of respiratory and cardiovascular mortality and morbidity due to short-term ozone exposure in 13 polluted communes across Chile’s Santiago Metropolitan and Valparaíso regions. Data on daily ozone, meteorology, and pollutants were sourced from the National Air Quality Information System (NAQIS), while health outcomes (mortality, hospital admissions, and emergency visits) were obtained from the Department of Health Statistics. A Poisson regression model, adjusted for trends, meteorology, day-of-week effects, and pollutants, quantified RRs for a 10 ppb ozone increase, ranging from 1.004 to 1.198 (95% CI). The highest risks were in Santiago’s Eastern zone (cerebrovascular, RR 1.171, 95% CI: 1.018–1.347), Western zone (cardiovascular, RR 1.198, 95% CI: 1.049–1.369), and Valparaíso’s Viña del Mar (ischemic heart disease, RR 1.127, 95% CI: 1.017–1.248). The 5–64-year age group was most affected, particularly in terms of emergency visits. Reducing ozone to the WHO guideline (100 µg/m3) could avoid 837,498 cases in Santiago and 17,992 in Valparaíso annually, resulting in economic savings of $7,439,930,640 and $1,044,568,800, respectively. These results highlight the need for stricter air quality policies to reduce ozone-related health burdens. Full article

Constructed wetlands (CWs) are eco-technologies used for wastewater treatment, where vegetation is a key component. In recent decades, the adaptability and phytoremediation functions of ornamental plants (OPs)—which are not typically found in natural wetlands—have been tested. However, few comprehensive studies address the processes or mechanisms by which these OPs enhance pollutant removal in CWs and their artisanal applications. It is also vital to understand the most used OP species in CWs and their advantages in phytoremediation. Thus, this study enhances the understanding of the processes involved in pollutant degradation within CWs, specifically focusing on absorption, adsorption, translocation, radial oxygen loss, and root exudates. It reaffirms the essential role that plants play in these systems, as suggested in previous scientific reports, and discusses some potential applications for the ornamental plants produced in CWs, such as flower arrangements and crafts. This also includes the social aspect, emphasizing community engagement through social capital initiatives for the adoption and appropriation of the ecotechnology. Additionally, a bibliometric analysis revealed that Mexico is among the countries with the most significant research on OPs in CWs, particularly concerning commercially valuable species, followed by India and China. These findings can be instrumental in planning future community projects focused on wastewater treatment using CWs using OPs. Full article
