This Repository Policy defines how and when authors may deposit versions of their work in external repositories (institutional, national, or subject-specific) in a way that supports open scholarship while respecting the journal’s publishing standards.
This policy applies to all articles published in the Nigerian Journal of Environment and Health (online, open access). All research and scholarly content published by NJEH is intended to be widely disseminated for maximum impact on policy, practice, and further research.
NJEH operates as an online open-access journal, providing research articles freely to readers without subscription charges. Authors retain rights to share their works consistent with this Repository Policy.
Authors may deposit preprints (manuscript drafts prior to peer review) on recognized public preprint servers (e.g., AfricArXiv, OSF Preprints) or on personal webpages before submission to NJEH. These must be clearly labelled as preprints and should include a footnote stating the manuscript is under consideration at NJEH.
After peer review and acceptance, authors may deposit the accepted manuscript (postprint) in:
This may occur immediately upon publication (no embargo), given NJEH is open access. If future changes to the journal introduce embargoes for any reason, the Editorial Office will publish those conditions publicly.
The final Version of Record (formatted, published journal PDF/HTML) archived on the NJEH website remains the authoritative copy.
Authors may link to the VoR in repositories but should not upload the formatted PDF directly to external repositories without clear licensing terms.
Unless otherwise stated, NJEH articles are published under a Creative Commons license (often CC BY or similar), which:
(Authors should consult the specific license on their published article for exact terms.)
Deposited versions (preprint or postprint) must include:
Suggested citation line:
Author(s) (Year). Title. Nigerian Journal of Environment and Health. Volume(Issue):pages. DOI: [link]
As an open-access journal, NJEH does not impose an embargo on depositing the accepted manuscript in repositories. Authors are encouraged to deposit immediately after publication.
If future policy changes introduce embargo requirements, these will be clearly communicated.
Authors are responsible for adhering to the open-access and repository policies of their funders or institutions. NJEH supports compliance with funder mandates by providing clear licensing and deposit information to authors upon publication.
Where applicable, authors should deposit underlying research data in recognized open repositories (e.g., Zenodo, Dryad, Mendeley Data) and include data availability statements in their articles.
