The publishing decision is based on the suggestion of the journal's reviewers and editorial board members. The ethical policy insisted the Editor-in-Chief, may confer with other editors or reviewers in making the decision.  The reviewers must evaluate the research papers based on the submitted content in a confidential manner.  The reviewers too suggest the authors improve the quality of the research paper through their reviewing comments.  Authors should ensure that their submitted research work is original and has not been published elsewhere in any language.  Applicable copyright laws and conventions should be followed by the authors.  Any kind of plagiarism constitutes unethical publishing behavior and is unacceptable.  For information on this matter in publishing and ethical guidelines please visit

After the accepted manuscript is published in an online issue

Any requests to add, delete, or rearrange author names in an article published in an online issue will follow the same policies as noted above and result in a corrigendum.


Journals should make clear the type of copyright under which authors' work will be published.  Upon acceptance of the manuscript, authors will be asked to complete a 'Journal Publishing Agreement' (MMB copyright form).  An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a 'Journal Publishing Agreement form or a link to the online version of this agreement.

Permission required

Permission should be sought from the publisher to reproduce any substantial part of a copyrighted work that depends on both the significance of the material and the quantity of material used. This includes any text, illustrations, charts, tables, photographs, or other material from previously published sources used.  If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners (publisher) and credit the source(s) in the manuscript.

Permission not required

Copyright protects only original (i.e. creative) material. As such it protects only the particular form of expression of a work, not the ideas or facts contained in it. Public domain works are not protected by copyright and may be reproduced without permission. Permission would however be required to re-use the final formatted, edited, published version of the work in certain cases, as it is owned by the publisher.

Author Agreement

In order to disseminate the authors’ research work, the publishers need publishing rights. For open-access articles the publisher uses an exclusive licensing agreement in which authors retain copyright in their manuscript (MMB copyright form)

Changes to Authorship

After the manuscript is submitted or accepted for publication, the corresponding author is required to send a request through the signed change of authorship form (ARMMT change of authorship form) to add or remove an author or to rearrange the author names of the submitted/accepted manuscript.

Creative Commons Attribution

Permit others to distribute and copy the manuscript, to create extracts, abstracts, and other revised versions, adaptations, or derivative works of or from the manuscript (such as a translation), to include in a collective work, to text or data mine the article, even for commercial purposes, as long as they credit the author(s), do not represent the author as endorsing their adaptation of the article, and do not modify the article in such a way as to damage the author's honor or reputation.  Further details found at Creative Commons Attribution 4.0 International (CC BY 4.0)

Conflict of Interest

Authors have requested evidence of whether impending conflicts do or do not exist. If an organization encompasses any financial interest in the outcome of the study, the authors are appealed to provide a declaration that they have full access to all the data in the study and take complete responsibility for the integrity of the data and the accuracy of the data analysis. All studies (if necessary, based on the type and subject), must be approved by the relevant Ethics Committee/ Institution review board of the respective institutions. Authors wishing to include figures, tables, or text passages that have already been published elsewhere are required to obtain permission from the copyright owner(s) for both the print and online format and to include evidence that such permission has been granted when submitting their papers. Any material received without such evidence will be assumed to be originated by the authors. A copyright transfer agreement is signed by the corresponding author, upon the acceptance of the manuscript, on behalf of all authors, for publication to be legally responsible towards the Journal ethics and privacy policy. Authors will be notified as soon as possible of decisions concerning the suitability of their manuscripts for publication in the journal. Once the article has been accepted for publication, it will be copy edited and typeset, after which the corresponding author will be sent information on accessing page proofs to correct. Other than the correction of typographical errors, alterations cannot be made at this stage. Please note that there are no page charges to publish in the Global Journal of Environmental Science and Management. The submitted materials may be considered for inclusion but cannot be returned and the Editors of the Journal reserve the right to accept or reject any article at any stage, if necessary.
