Origin, evolution, currents of thought, and methodological implications of the agroecosystem concept: a review
Bibliographic record
Abstract
ABSTRACT. The objective of the research was to analyze the different currents of thought and to describe the origin and evolution of the concept of agroecosystems across different studies. Methodology. A state-of-the-art analysis of the agroecosystem concept was conducted using the Web of Science platform, considering 225 articles with the TITLE "Agroecosystem" AND KEYWORDS "Agroecosystem." Metrics such as year, country, sustainable development goals (SDGs), language, summary, and conclusions were also considered. A bibliometric analysis was performed using VOSviewer software, and graphs were created to visualize the bibliographic connections between the documents obtained from the Web of Science database. Results. Articles from 1991 to 2024 were identified, with over 90% published from 2018 to the present. The top countries publishing this type of research are the USA, China, Canada, France, Germany, and Italy, accounting for 82% of the publications. The remaining 18% are spread across 44 countries worldwide. The predominant language is English (96%), followed by Spanish (3.1%) and Russian (1%). Conclusions. The concept of agroecosystems is embedded in the social, cultural, political, and economic contexts, as all these aspects are directly related to agriculture, livestock, fishing, and other essential activities for feeding humanity. These activities are carried out within agroecosystems managed by humans for both commercial and self-consumption purposes, aiming to satisfy society's demand for food, goods, services, and inputs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
