Guide for Authors
Type of Manuscript
- The manuscript (including text, figures, and tables) and the cover letter should be submitted electronically via TPJF website under
Publish>Submit Manuscript, or e-mail us directly at firstname.lastname@example.org. Please use the manuscript and the cover letter templates provided by the journal. It is expected that authors have read our Publication Policy.
- The manuscript should be prepared in a Microsoft Word format (.doc or .docx), and the file name should be clearly labeled with the corresponding author’s last name. Please ensure you provide all relevant editable source files at every submission and revision. Failing to submit a complete set of editable source files will result in your article not being considered for review.
- A research article is a full-length paper reporting new research findings with sufficient details for validation and reproducibility. It should be approximately 5000-8000 words long, including abstract, acknowledgment, and references.
- A review article is a critical review presenting objective synthesis and assessment of topics within the scope of the Journal and carefully interpreting and critiquing said knowledge based on available literature. It is more flexible in terms of format and length but is stricter on having at least 30 literature references, preferably published over the last five (5) years. A review article may be submitted directly or by invitation.
- A short communication is a concise but complete description of new concepts, investigations, experimental methods, models, technical operations or applied activities to inform readers of development in a particular research area. It is more flexible in terms of format, but it must include references and a detailed description of the methodology and must not exceed three (3) pages or approximately 4000 words, including the references, tables, and figures.
- A commentary is a scholarly article which expresses a personal opinion or a new perspective about existing research on a particular topic. A commentary may be commissioned by the editor-in-chief or editorial board members, or spontaneously submitted. They are not minireviews. Commentaries do not include original data and are heavily dependent on the author’s perspective or anecdotal evidence from the author’s personal experience to support the argument. It should be approximately 1000-1500 words long. No need for abstracts or key words. However it should contain the following:
- Background - This should explain the background to the article, its aims, a summary of a search of the existing literature and the issue under discussion.
- Main text - This should contain the body of the article, and may also be broken into subsections with short, informative headings.
- Conclusions - This should state clearly the main conclusions and include an explanation of their relevance or importance to the field.
- A policy brief is a “concise summary of a particular issue, the policy options to deal with it, and some recommendations on the best option” (FAO Food Security Communications toolkit). It is aimed at government policymakers and others who are interested in formulating or influencing policy. It is more flexible in terms of format and length but is typically a single sheet, containing, around 700 words, has an attractive design, and may have one or more photographs. Longer briefs can take up to 8 pages or 3,000 words.

- General Guidelines
- The manuscript should be submitted and compiled in the following order: Title page; title, abstract, and keywords; main text; acknowledgments; supplementary material (if applicable); author contributions; conflicts of interest; ethics statement; references; tables with captions. All figures should be submitted in a separate file.
- The manuscript text should be in Times New Roman, 12 point, double-spaced, with at least one-inch margin on each side, justified throughout, and with continuous line numbers
- TPJF adopts the Scientific Style and Format developed by the Council of Science Editors. Refer to their website for your in-text citation and reference list.
- Figure captions should appear below each figure, flush left.
- Figure formats should be 600 dpi in TIFF/JPG/JPEG format.
- Measurements should adhere to the internationally accepted rules (i.e., international system of units or SI). Do not italicize the units. Kindly consult this website.
- Page numbers are at the right bottom of the page.
- Abbreviations should be defined at first mention and used consistently thereafter
- Manuscript Structure
- Title page shall contain the following:
- Type of article (e.g., original research, short communication, review article, commentary, policy brief);
- Title of the article;
- Author/s’ full name/s, affiliations, mailing addresses, e-mail addresses, and ORCID
- Identify the corresponding author (the primary contact person of the editors).
- Manuscript text must be separated from the Title Page with a page break. It should contain the following:
- Abstract – maximum of 250 words are required for all types of manuscripts;
- Key Words – three (3) to six (6) words to identify the most important topics covered in the paper and for indexing purposes;
- The main text should be structured and numbered consecutively as (depending on the type of manuscript): 1. Introduction; 2. Materials and Methods; 3. Results; 4. Discussion; 5. Conclusion. Acknowledgment, supplementary material (if applicable), author contributions, conflicts of interest, ethics statement, and references need not be numbered but they must be properly labeled.
- Tables should appear at the end of the text, after the References section. Do not embed tables and figures in the text.
- They should be numbered in the order in which they appear in the text (e.g. Table 1, Table 2, etc.). Contents (including captions) must be set in Times New Roman 12 point.
- Table captions should appear above each table, flush left. Any legend or footnotes must be clearly identified below the table. Avoid vertical lines.
- Figures should have the highest quality format possible. Photographs and scanned materials should be of a minimum resolution of 600 dpi in TIFF/JPG/JPEG format.
- Because figures are usually large files, send them in a separate document complete with captions appearing below the figure, flush left, Times New Roman, 12 point.
- Figures should be numbered in the order in which they appear in the text (e.g. Figure 1, Figure 2, etc).
- Maps should have the following elements: scale bar, north arrow, latitude/longitude (graticule lines), legend, and inset/locator maps. Maps should be georeferenced or drawn using appropriate software or application. You may check this source to be guided on designing maps for scientific publication.
