Post-harvest cereal structures and climate change resilience in rural Zimbabwe: a review

Abstract

Farmers in Sub-Saharan Africa use storage structures that help maintain grain quality and safety. This study reviewed the use of different grain storage structures used by smallholder farmers in Zimbabwe namely granaries, metal silos, supergrain bags, polypropylene bags and cribs. Metal silos and supergrain bags, however costly, have hermetic properties that kill pests while granaries dilapidate with time. Cribs are susceptible to moisture entry, while polypropylene bags are prone to perforations by sharp objects. This review discussed the impact of climate change on preservation of grain quality during storage. Moulds, insect pest infestations and rodent attacks are major challenges that cause storage losses. Knowledge barriers, cost, fear of the unknown, effectiveness of storage structure and security of grain are factors that affect the diversity of storage structure use. Proper use of storage structures contributes towards achieving sustainable development goals and increases farmer resilience to the impacts of climate change.
