“…Storage management of harvested grains and measures to prevent the insect from thriving in stored grains is of great concern to food processing and storage industries (Paul et al, 2020). Storage structures and facilities extend shelf life and reduce PHLs by protecting grains against environmental factors, rodents and insects (Mapfeka et al, 2019). Restriction on the utilization of insecticides during storage makes grains storage more challenging and even under optimum storage conditions, grains can be contaminated by insects (Shlomo Navarro and Navarro, 2016).…”

“…An acoustic insect detection method will detect both hidden and open insects in stored grains without opening the storage structure. The technology involved the use of sound software that collected insect noise, screened and amplified them, and classified them based on their amplitude (Banga et al, 2019) Farmers use different storage systems in different locations of the globe, traditional facilities used include granaries, cribs (Mapfeka et al, 2019), gunny bags and wooden boxes (Manandhar et al, 2018). Traditional storage structures are used mainly by smallholder farmers in developing countries (Tibagonzeka et al, 2018).…”

“…Traditional storage structures are used mainly by smallholder farmers in developing countries (Tibagonzeka et al, 2018). Traditional storage structures are not very reliable, grain quality can easily be compromised and the structure can dilapidate easily (Mapfeka et al, 2019). Traditional storage and handling facilities are ineffective against mold and insects ( Kumar and Kalita, 2017;Manandhar et al, 2018;Sankara et al, 2016) and are influenced by the external environment, grains can quickly develop mold during the wet seasons, loss their quality and develop safety issues (Garbaba et al, 2018).…”

Grains (cereals and legumes) are universal foods that provide calories, proteins, essential minerals and vitamins. They are essential to the nutrition of many including infants and children. Attack by insects and microorganisms, particularly fungi, during drying, storage and processing, affects the quality, safety and market value of grains. Fungal attacks before or during drying can be disastrous, the effect can persist throughout the supply chain. Postharvest grain losses pose challenges to food and nutritional security, public health, and many developing nations' economy. Postharvest storage structures and packaging materials are expected to extend the shelf life of the grains by protecting them from insects, microorganisms, environmental factors and making the microenvironment unfavorable for insect and microbial activities. Traditional storage and packaging materials are highly inefficient in this sense and are associated with quality degradation. Traditional storage and packaging materials commonly used by farmers, mostly in developing countries, include granary, crib, wooden box, gunny bag and polypropylene woven bag. Modern storage and packaging materials commonly used are metal silo and hermetic bags; they are effective but unfortunately cannot be afforded by most farmers in developing countries. The article reviewed postharvest storage management of cereals and legumes. Literature was gathered through a comprehensive literature review. The use of various traditional storage and packaging materials for grains was debated. Techniques for the prevention of postharvest losses were extensively discussed, emphasis was given to novel technology and the use of natural insecticides. Challenges associated with controlling postharvest losses were also summarised. In the end, research gaps were identified and recommendations were provided about minimizing grain contamination and postharvest losses.

“…On the other hand, lack of appropriate storage facilities for harvested farm produce encouraged farmers to sell away their produce immediately after harvesting at a lower price compared to cost of buying food afterwards (Zachary Gitonga, 2015). Furthermore, resent studies indicate that, global warming and other changes in the environment caused by pollution of the ecosystem is forecasted to alter and change insect pest behavior process through mutation over and above growing mould infection of stored grains thereby increasing post-harvest losses and hunger in Africa and other developing countries (Rudo Florence Mapfeka, 2019). Metal silos and supergrain bags, remain common for their usefulness in conserving grain class but are very costly and out of reach of ordinary rural farmers.…”

“…Metal silos and supergrain bags, remain common for their usefulness in conserving grain class but are very costly and out of reach of ordinary rural farmers. Traditional granaries and cribs depreciate over prolonged use encouraging wetness and grain decomposition, while polypropylene bags are vulnerable to punctures that cause reduced grain quality (Rudo Florence Mapfeka, 2019).…”

<p>In the past several decades, domineering influence from the western culture has played an important role in Africans abandoning their traditional foods for the more appearing western cuisines and highly refined factory foods. Unfortunately, this approach results in problems related to increase in lifestyle diseases such as diabetes, obesity, impotence in men, high blood pressure and cancer to name but a few. This problem has been largely studied and many viable solutions have been found including going back to consumption of traditional foods. Consequently, there has been much campaign and spirited debate in the media for the need to return to the consumption of African traditional foodstuffs to try to reduce the spread of the lifestyle diseases. On the same note, African communities have abandoned their traditional farming practices including food storage and warehousing practices. This turns out to be even more problematic because instead of improving their traditional food storage practices like granaries, on the contrary they have adopted urban systems, which have proved ineffective and inefficient. For instance, such poor storage practices include the following: the use of converted storage rooms in modern urban residential houses; construction of stock yards and sheds using cheap scientifically untested materials, poorly built traditional granaries due to loss of artisanship and knowledge from one generation to another and use of shopping bags and plastics. This is a basic chicken-and-egg problem, therefore, this article encourages the need for new research initiatives aimed at coming up with a newly designed African granary as a solution to reducing postharvest losses by rural farmers in Kenya and other developing countries. Other studies have failed to come up with a viable solution to the problems occasioned by the traditional African granary and the modern versions in the markets. The aims of this research are twofold: firstly to find engineering solutions to the practical and applicability challenges facing the traditional African granary, secondly, to design a commercially viable technically practical traditional African granary prototype. Therefore, this paper evaluates the past and currents trends in the use of the African granary and proposes new technical improvements to make it more suitable in combating pest, rodents and disease invasion. This shall be done, by searching for appropriate literature on the current problems associated with the granary and forecasting the economic, technical, socio-cultural, governmental and legal benefits of a newly designed traditional African granary. This thesis will document several key contributions made to the fields of warehousing and stores management: to reduce post-harvest losses by 90% therefore combating food shortage and hunger in Kenya and other developing countries of the world. </p>

Many stakeholders in agro-food industry are concerned about sustainability, especially in addressing post-harvest loss (PHL). However, resources available to various supply chain stakeholders such as in the raw cashew nuts (RCNs) supply network to address PHL remain a challenge. The extant literature on PHL has limited intricate insight into its drivers from the perspective of resources. This paper, focusing on RCNs supply network, systematically identifies and analyzes critical drivers that influence PHL guided by tangible and intangible resources perspective. Fuzzy-Decision Making Trial and Evaluation Laboratory (Fuzzy-DEMATEL) methodology was employed to analyze and convert an experts' judgment into quantifiable data to establish the causal relationship among the drivers. The findings reveal that urgent and short-term attention to address PHL in the RCNs supply network should be given to the primary tangible driver of lack/insufficient proper packaging materials. Furthermore, in medium-term strategies, RCNs suppliers and government agencies in-charge of agriculture and industry bodies need to surmount three key cause drivers consisting of premature/green harvesting of cashew nuts, financial and economic constraints, and lack of appropriate storage facility. In addition, drivers such as insufficient/lack of management support and commitment and lack of information dissemination on PHL within RCNs suppliers should be addressed in the long term. The study provides a framework for supply chain managers and policymakers to understand the interrelationship among PHL drivers from a resource perspective to enable the implementation of strategies that address PHL.
