Lessons from the old Green Revolution for the new: Social, environmental and nutritional issues for agricultural change in Africa
Bibliographic record
Abstract
Recent efforts for an ‘Alliance for a Green Revolution in Africa’ (AGRA) promote fertilizer, hybrid seeds, pesticides and biotechnology to increase agricultural production. This article examines the original Green Revolution to understand potential effects of a recent promotion of related technologies in Africa. Using a case study of Malawi, the implications of promoting high-input, intensive agriculture on food security, social relations and nutrition are considered. I argue that unless social inequalities and environmental concerns are taken into account, these technologies will intensify inequalities, increase environmental degradation and exacerbate malnutrition for the rural majority, while benefitting the urban poor, larger-scale farmers, agro-input dealers and transnational corporations involved in agribusiness.

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.
