“…In the inefficiency component of the model, the use of raised beds, sowing and harvesting at the recommended dates, and farmers' experience with past projects which disseminated similar wheat technology packages all are highly significant (p < 0.01) in reducing technical inefficiency. All these results are consistent with the theoretical expectation because, being instrumental in reducing the quantity of water needed per ha and increasing yield [51], raised beds effectively enhance efficiency in the Egyptian wheat fields. The recommended planting and harvesting dates were also meant to increase yield and efficiency (or reduce inefficiency).…”

Pushing yield frontiers of cereals and legumes is becoming increasingly difficult, especially in drylands. This paper argues and provides empirical evidence that food loss and wastage constitute a sizeable proportion of the total wheat supply in Egypt. By following the life cycle of food and using standard measurement protocols, we estimated the levels of food loss and wastage along the wheat value chain in Egypt and their socioeconomic, biophysical, and environmental implications. About 4.4 million tons (20.62% of total wheat supply from domestic production and imports in 2017/2018) is estimated to be lost or wasted in Egypt which is also associated with the wastage of about 4.79 billion m3 of water, and 74.72 million GJ of energy. This implies that if Egypt manages to eliminate, or considerably reduce, wheat-related losses and wastage, it will save enough food to feed 21 million more people from domestic production and hence reduce wheat imports by 37%, save 1.1 billion USD of much-needed foreign exchange, and reduce emissions of at least 260.84 million kg carbon dioxide-equivalent and 8.5 million kg of methane. Therefore, investment in reducing food loss and wastage can be an effective strategy to complement ongoing efforts to enhance food security through productivity enhancement in Egypt.

“…Wheat crop (Triticum aestivum vulgare L.) is one of the three most important cereal grains on the earth worldwide (Cheng et al, 2021), and is the greatest one, especially in Egypt (FAOSTAT, 2019). The Egyptian wheat production represents 20% of agricultural imports and around 10% of total agrarian production (FAOSTAT, 2019;Yigezu et al, 2021). The total cultivated area of Egyptian wheat in 2021 reached about 3.6 million Feddan and the total production is 9.3 million tons (FAO, 2021).…”

“…The total cultivated area of Egyptian wheat in 2021 reached about 3.6 million Feddan and the total production is 9.3 million tons (FAO, 2021). This production is insufficient for Egyptian consumption of wheat, and therefore Egypt is considered as the world's biggest buyer from other countries to compensate for the food gap (Yigezu et al, 2021). Around 10-20% of the Egyptian wheat grain production is lost due to insect pests and climate change during the traditional storage (Matouk et al, 2017;Yigezu et al, 2021).…”

The rice weevil, Sitophilus oryzae L., is a destructive internal feeder in stored grains of strategic crops in Egypt. Diatomaceous earth (DE) is a natural substance as a physical method free of toxic residues in the storage ecosystem. A laboratory experiment was conducted to study the impact of diatomaceous earth (DE) on the Sitophilus oryzae L. as well as on wheat seed germination. Various concentrations of DE were selected at 13, 11, 9, 7, 5, 3, 1, 0.5 and 0.25 mg in addition to the control treatment without DE. Mortalities in S. oryzae adults reached 100% at rates of 11 and 13 mg DE after 6 th and 7 th days of adult exposure compared to 0% mortality recorded in untreated grains. Furthermore, the treated grains with DE at 0.25 and 0.5 mg within 1 st and 2 nd days of exposure were unable to protect the stored grains against S. oryzae,while the seventh day of exposure had effective results of protection. Seed germination was only tested on the treated wheat grains within 7 days of exposure. Results indicated that the germination rate was accelerated as it reached 99% at higher doses of DE (11 and 13 mg) compared to 53% in the untreated seeds. Agro-morphological characters of tested seeds were also highly improved. The seedling length reached 59.41 cm compared with 24.30 cm for untreated seeds. The seedling Vigor index at 13 mg DE was greater (5881.59) than the control (1287.9). The present work demonstrated the effectiveness of DE at 13 mg DE/100g on the 7 th day of release to combat rice weevil in cereals storage environments on a sustainable basis. DE was found to be an ecofriendly physical method for sustainable pest management in the wheat storage ecosystem.
