Dataset of source verification, thematic coding and co-occurrence structure for agrifood system transition lock-ins in Zambia

It comprises 63 verified analytical sources coded across 14 themes grouped within political, economic, environmental and social system dimensions. The deposited files include theme definitions, a source by theme binary coding matrix, the complete list of 91 pairwise theme co-occurrences, a 14 × 14 co-occurrence matrix, source data used for the corpus profile, the original thematic coding workbook, a data dictionary, and supporting reproducibility files.

Each source is assigned a unique identifier that permits cross-checking of bibliographic information, verification status, and thematic assignments. The dataset is intended to support reproducibility and secondary analysis of the associated Agricultural Systems study, including recalculation of theme frequencies, examination of alternative co-occurrence thresholds, auditing of coding decisions, and comparative application in other agrifood-system transition studies.
