Food system flows and distribution for the Accra metropolis: Unfolding the policy dimensions
Bibliographic record
Abstract
The continuous growth of cities in developing countries portends the challenge of food provisioning. This study therefore examined the policy dimensions of food flows and distribution for the Accra metropolis. The study methodology involved review of policy documents, interviews with government officials and city authorities, and discussions with a cross-section of food commodity traders at the city’s markets. The study established that the city’s food region is very extensive with the principal food staples originating from distant areas. The city’s local markets (and numerous informal markets) are very important in the food distribution network. However, they are characterised by inadequate infrastructure, poor waste management and congestion in view of poor planning. There is no composite national policy on city food supply and distribution apart from discrete programmes that seek to encourage partnership between city authorities and the private sector for the development of market infrastructure. The paper advocates for comprehensive national policy to ensure well-defined rural-urban linkages and city level agenda for sustainable food access in the city.

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.
