Unraveling Factors Affecting Food Waste Globally: A PRISMA-Based Systematic Literature Review and Bibliometric Analysis
Bibliographic record
Abstract
This study utilizes a systematic literature review and bibliometric analysis, following the PRISMA method, to explore behavioral and contextual factors influencing food wastage based on literature published from 2019 to 2024.It identifies key determinants such as perceived control, consumer intention, attitudes, subjective norms, religiosity, and household dynamics.Perceived control notably correlates with up to a 20% reduction in household food waste.The research highlights a scholarly trend towards incorporating sustainability into the food supply chain, with a focus on bioenergy recovery from waste.It also examines sociodemographic, cultural, and psychological influences on food wastage behaviors across various regions, illustrating the complexity of these behaviors and the need for tailored, region-specific approaches.The findings advocate for an interdisciplinary strategy that merges design, technology, and behavioral science to enhance food waste management systems.Such strategies should be adaptable to different cultural contexts and aim to minimize ecological footprints, supporting global sustainability goals.The implications suggest that policymakers and practitioners should develop sustainable, design-oriented solutions that account for local behaviors and systemic capacities to effectively curb food waste.This approach promotes culturally sensitive and environmentally sound interventions, leading to significant reductions in global food wastage.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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, unvalidatedLabeled directly by 2 models reading the full record.
