Writing Style (agsy-writing-style)

An AgSy paper must be readable by a broad systems-science audience — agronomists, modellers, economists, and environmental scientists — and prepared with the journal's front matter. This skill is about communicating a systems analysis clearly and meeting Elsevier's format, not about generating claims.

When to trigger

• Drafting the introduction, framing the contribution, or final polish
• Writing the ≤ 250-word abstract, the Highlights, or the graphical abstract
• Tightening a long methods/results section toward the ~8,000-word guideline
• Aligning references and format to the journal's style before submission

Reach the systems-science audience

1. Front-load the systems contribution. By the end of the introduction the reader knows the system, the interaction/trade-off in question, the modelling approach, and why the result matters. Don't make a reader dig for the "so what."
2. Define the system early. State boundary, components, and hierarchical level so a non-specialist in your exact subsystem can follow (see agsy-systems-framing-and-modeling).
3. Explain the model in plain terms first, then in detail. A reader should grasp what the model does before meeting its equations.
4. Argument-first prose. Lead with the systems insight; use model output and statistics to support it. Avoid "the model shows…" without saying what it shows about the system and why it matters.
5. Signpost. Clear IMRaD-style structure so a reader can navigate framing → model → evaluation → trade-offs → implications.

Format & front matter (source map refreshed 2026-06-20)

• Abstract: ≤ 250 words, stating purpose, principal results, and major conclusions.
• Highlights: 3-5 short bullet points, each no more than 85 characters including spaces.
• Graphical abstract: a separate figure file summarizing the work for an interdisciplinary audience — often a conceptual system diagram or a trade-off result; live-check current size/format specs.
• References: format to the journal's style; manage with Zotero/Mendeley/BibTeX (Elsevier elsarticle for LaTeX).
• Declarations: CRediT roles, declaration of competing interest, funding, and AI-use disclosure where applicable (see agsy-submission).

Length discipline (research paper ~8,000 words; no hard cap)

• Move full calibration tables, parameter lists, and exhaustive scenario grids to supplementary material.
• Cut throat-clearing and literature dumps; engage the systems debate, not every paper.
• Prefer one decisive trade-off figure to three redundant tables.

Anti-patterns

• An intro that never states the systems contribution or the trade-off at stake
• An abstract over 250 words, or one that hides the result; missing Highlights / graphical abstract
• Dropping a model's equations on the reader before explaining what it does
• Describing a single factor as if it were a system; burying the interaction
• Mixed reference styles or missing declarations

Section-by-section moves for a systems paper

Write each section to answer the question a systems referee raises there. Title: name the system and the trade-off, not just the crop. Abstract: lead with the interaction, end on the decision (≤250 words). Introduction: state boundary, interaction, model, and stakes by the last paragraph. Methods: plain-language model first, equations second. Results/Discussion: lead with the trade-off, then tie it to the decision and match claims to uncertainty.

Worked micro-example: tightening one abstract sentence (illustrative)

Before (buries the system): "Simulations were run for several management options and yields compared across scenarios." — passive, no interaction, no trade-off, no decision.

After (systems-first): "A whole-farm bioeconomic model shows that shifting 30% of area to a legume intercrop raises modelled gross margin ~8% but increases nitrogen surplus ~14%, sharpening a margin–environment trade-off advisers must weigh when targeting rotation subsidies." — interaction, quantified trade-off (illustrative), and decision in one sentence.

Referee pushback on writing → the AgSy-specific fix

• "I could not tell what the system was." → Add a boundary-and-components sentence plus a conceptual diagram early; define the hierarchical level explicitly.
• "The contribution reads as single-discipline." → Reframe the intro around the systems debate and engage both the domain and modelling literatures (see agsy-literature-positioning).
• "The model arrives as a wall of equations." → Lead with plain English on what it does.

Calibration anchors (hedged where uncertain)

• The ≤250-word abstract, Highlights, and graphical abstract are standing Elsevier front-matter expectations; confirm exact requirements on the current author guidelines.
• The ~8,000-word figure is a guideline, not a hard cap — judgment plus current guidance governs length.
