“…15 The validation study also confirmed that storage structures without PVC bags exhibited more than 47% damage after six months of storage (Table 3) which is even lower than that was reported (64.5%) by Sori and Ayana. 3 Weight loss of grains was also associated with the number of live weevils and percentage of damage as indicated above. Partial modified-atmosphere hermetic environment created using smoke infusion and PVC bag reduced the weight loss to less than 2% as compared to more than 20% in controls (T3 and T7) ( Table 4).…”

BACKGROUND: Production and marketing of cereal grains are some of the main activities in developing countries to ensure food security. However, the food gap is complicated further by high postharvest loss of grains during storage. This study aimed to compare low-cost modified-atmosphere hermetic storage structures with traditional practice to minimize quantitative and qualitative losses of grains during storage. The study was conducted in two phases: in the first phase, seven hermetic storage structures with or without smoke infusion were compared, and one selected structure was further validated at scaled-up capacity in the second phase. RESULTS: Grains stored in PVC bag-supported structures (with or without smoke infusion) resulted in low live weevil population, low percentage of damaged grains and reduced weight loss with better retention of crude protein and fat contents. Results fromvalidation study also demonstrated that maize and sorghum stored in improved storage structures experienced, respectively, 9.8% and 10.4% weevil damage as compared with 47.3% and 42.3% when stored in traditional storage structures. The same was true in terms of crude protein and fat contents. CONCLUSIONS:The study demonstrated that storage structures supported with PVC bags are efficient and low-cost structures for reducing storage-related losses and supporting food security efforts as compared to traditional methods. Furthermore, the bags can be made locally and with various storage capacities to store either shelled or unshelled products. /jsfa * Means within a column followed by the same letter(s) are not significantly different at P < 0.05%.

One of the main challenges facing Ethiopia today is ensuring food security, as the country demands more food than before with the increase in population. Although the country's production is much lower than the national demand, there are high postharvest food losses, largely due to limited food processing, preservation, and storage capacity. Universities and research centers in the country had been done and doing research on the postharvest activities to assure effective and sustainable methods of food security enhancement strategy. In contrast, most of the strategies and technologies they develop never get implemented by farmers as they still rely on indigenous knowledge for postharvest activities. Although people are using indigenous knowledge, their contributions and potentials in food processing, preservation, and storage are underestimated. However, indigenous methods of food preparation, preservation, and storage are time tested and have been used by locals people over generation to preserve their produce after harvest, thereby serving as a survival strategy. Moreover, the country is blessed with various types of wild edible plants and also possesses diverse indigenous knowledge systems for their processing, preservation, and storage. These indigenous foods are inexpensive to use, safe, nutritious, and thus boosting overall food security. Therefore, the aim of this review paper is to document indigenous knowledge of food storage, processing, and preservation in the country. This could help as a gateway to verify and support indigenous knowledge with latest technologies and promote their role in attainment of food security.

Gendering post-harvest loss research: responsibilities of women and men to manage maize after harvest in southwestern Ethiopia

et al. 2022

View full text Add to dashboard Cite

Post-harvest losses are a significant problem worldwide, leading to a waste of resources when they are becoming scarcer. Rather than putting more energy into increasing production volume, addressing post-harvest losses can increase food availability without increasing yields. Using maize in Ethiopia to introduce gendering post-harvest loss research, we analyze the gendered division of labor in post-harvest management and then discuss implications. The study was conducted from 2014–2015 in southwestern Ethiopia as part of a broader research project from 2013–2018. Semi-structured interviews were conducted with 208 male and female farmer heads of household. Our results show that although maize post-harvest activities are deemed to be the responsibility of women, the overall management of maize after harvest requires the cooperation of all household members. For example, both women and men contribute to time-sensitive harvest, packing and de-husking activities. Men tend to have the responsibility for ensuring that maize is stored well. Critically, women tend to sell small quantities of maize to pay for everyday household expenses including purchasing other foods to diversify diets. Often recommendations in literature to reduce maize post-harvest losses include building processing centers and formalizing the supply chain. However, as shown in this research, women’s role to decide which maize to consume in the home and which to sell is important for access to quality food. Without gendering post-harvest loss research, it is possible that gender harms are enacted when women’s livelihoods are impacted in the process of reducing post-harvest losses, and this may compromise food security.
