• Empirical framework:  The methodology section should be detailed to enhance clarity and enable replication if need be. It should include empirical models and relevant diagnostics for model fit, data sources, measurement of variables, study area each presented as a sub-section in this chapter. If you are using observational data to measure the effect of X on Y then you need to clearly explain the identification strategy. For example, if you are estimating the impact of a new agricultural technology on yields, consideration needs to be given to the endogeneity/selection bias that can affect your estimates because the technology adoption is likely not to be random.
• Equations:  Please ensure that equations are editable.
• Results reporting:  Report your  significant  results in ways that are appropriate depending on the nature of results e.g., tables, figures and maps.  Tables and Figures  should be included in the article in the correct place and not in a separate file. Number the Tables and Figures consecutively and give each a caption –  above  for a Table and  below  for a Figure. Figures should in black and white. Type any notes below the Tables and Figures, and refer to these by superscript lowercase letters.  Tables and Figures must be original and not cut and pasted. No tables, figures or maps from any other publication will be accepted without the publisher’s permission attached at first submission of the article.
• Tables:  Tables should present new information rather than duplicating what is in the text. Readers should be able to interpret the table without reference to the text. Please supply editable files.  Tables  should have full gridlines and the contents should be in Times New Roman 10-point font. All measurements should be in  SI  units.
• Results Discussion:  Discuss your  significant  results in depth. Results discussion should include bringing out their deeper meaning and implications for policy and practice. Cite literature to enhance credibility of your results. Explain discrepancies of your results with those reported in literature.
• Conclusions and Recommendations:  In a brief, draw conclusions of your study from the  significant  results only. Each conclusion should lead to a logical and actionable recommendation(s). Recommendations should precise, actionable and targeted to a particular audience including policy makers and practitioners. Recommendations should be based on the significant results only. Any significant study limitation should be mentioned here.
• References:  Try to limit number of citations to a maximum of 25. Cite peer-reviewed journal articles and books from reputable authors and publishers. Avoid citing grey literature (e.g. working papers, policy reports, dissertations and other documents that have not been peer-reviewed). Most of the citations should be from economics or agricultural economics journals, although a few citations from other disciplines is fine. DO NOT cite articles in predatory journals.
• Publication Charges:  There are no submission fees, publication fees or page charges for this journal. However, authors of papers that have been accepted for publication will be required to become members of the African Association of Agricultural Economists by paying the requisite  membership fee .
• Funding details:  Please acknowledge funders of your study by stating; This work was funded by the [ Funding Agency ] under Grant [ number xxxx ] where applicable. If the authors did not receive financial support, state  ‘This study was funded by the Authors’ .
• Conflict of interest declaration:  Declare any conflict of interest with regard to your study. If no conflict of interest exists, indicate ‘None’.

How to publish in this journal

The set of journals have been ranked according to their SJR and divided into four equal groups, four quartiles. Q1 (green) comprises the quarter of the journals with the highest values, Q2 (yellow) the second highest values, Q3 (orange) the third highest values and Q4 (red) the lowest values.

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Evolution of the number of published documents. All types of documents are considered, including citable and non citable documents.

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Evolution of the total number of citations and journal's self-citations received by a journal's published documents during the three previous years. Journal Self-citation is defined as the number of citation from a journal citing article to articles published by the same journal.

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.

International Collaboration accounts for the articles that have been produced by researchers from several countries. The chart shows the ratio of a journal's documents signed by researchers from more than one country; that is including more than one country address.

Not every article in a journal is considered primary research and therefore "citable", this chart shows the ratio of a journal's articles including substantial research (research articles, conference papers and reviews) in three year windows vs. those documents other than research articles, reviews and conference papers.

Ratio of a journal's items, grouped in three years windows, that have been cited at least once vs. those not cited during the following year.

Evolution of the percentage of female authors.

Evolution of the number of documents cited by public policy documents according to Overton database.

Evoution of the number of documents related to Sustainable Development Goals defined by United Nations. Available from 2018 onwards.
