Background (ii) extension services multiply adoption probability 2.8-fold and secure land tenure increases long-term CSA investment by 60%; (iii) Ghana generates approximately 13,000 tonnes of municipal solid waste daily, of which 61% is organic and largely untapped as compost feedstock; (iv) microplastic contamination (1,100–2,700 particles kg⁻¹ of organic amendments) constitutes an emerging 'compost quality paradox'; and (v) critical policy coherence gaps persist between agricultural and waste governance instruments. Conclusion: The review concludes with a six-point research agenda and recommends the creation of an integrated Waste-Agriculture Nexus policy mechanism to bridge institutional silos and unlock Ghana's organic waste potential for sustainable food systems.
