Publishing Ethics and Policies

NIJEST is committed to promoting the highest practise of ethical publication. Allegations of misconduct will be thoroughly reviewed, as discussed in the related sections below, and in compliance with the guidelines of the Committee on Publication Ethics (COPE).

Evaluation of Submitted Articles

All articles submitted are subject to peer examination and are required to conform with academic quality requirements. If approved by the editor, submissions will be considered by anonymous peer reviewers who are experts in related fields.

Originality and Plagiarism

The author(s) shall confirm that the entire work is original and unpublished; it is submitted only to the Nigerian Journal of Environmental Sciences and Technology (NIJEST) and all text, data, figures/tables or other illustrations included in the work are completely original and unpublished, and these have not been previously published or submitted elsewhere in any form or media whatsoever. The author(s) shall also confirm that the paper contains no material that would violate the copyright or any other right of any other person. The authors will obtain and include with the paper where applicable written permission from any respective copyright owners for the use of any textual, illustrative, or tabular materials that have been previously published or are otherwise copyrighted and owned by third parties. All copyrighted material shall be clearly identified and properly acknowledged within the text.

NIJEST uses a third party software to detect submissions overlapping with published and submitted work. If the article do not exceed a limiting similarity level (15%), the articles may need to be corrected otherwise, the article will be withdrawn. Articles considered to have been plagiarised, whether before or after publication in NIJEST, would be retracted and the author(s) may face sanctions and barred from submitting articles to NIJEST in the future.

Duplicate and redundant publication

Duplicate publication is not acceptable in NIJEST. Authors must avoid duplicate publication, which is reproducing verbatim content from their other publications.

Anyone listed as an author in the paper should have made a substantial, direct, intellectual contribution to the work.

If a paper is found to violate the duplication policy, NIJEST editorial board shall refer to the COPE Flowcharts[1] for further necessary action

Fabrication, Falsification and Image Manipulation
