Adoption and impacts of hermetic storage on household food insecurity among maize producers’ organizations in Tanzania

We utilize a unique dataset comprising 1180 households affiliated with maize producers' organizations (POs) in the Rukwa and Ruvuma regions of Tanzania to analyze the adoption and impacts of hermetic storage technologies (HSTs) on the quantity of stored maize, measured in kilograms (QSM), and the Household Food Insecurity Access Scale (HFIAS). The study employs the logit and endogenous switching regression models to generate results. We find that, among other factors, the presence of HST vendors in the local community and training on proper HST usage are crucial in the adoption of HSTs among POs. Additionally, the usage of storage pesticides is negatively and significantly correlated with HST adoption. This suggests that farmers employing chemical insect pest control methods are less likely to adopt HSTs. The adoption of HSTs is shown to increase maize storage quantities by 40% and decrease household food insecurity by 43%. Further analysis based on the gender of the household head demonstrates that both female- and male-headed households benefit equally from the adoption of HSTs. The results advocate for the promotion of HSTs as a viable solution to mitigate household food insecurity among members of maize POs in Tanzania.
