Post-harvest wheat losses in Africa: an Ethiopian case study

Over 90% of global yam production is from West Africa where it provides food and income for above 300 million smallholders’ farmers. However, the major challenge of yam is 10–40% post-harvest losses due to the lack of appropriate storage facilities. This paper assesses a biogas-driven cogeneration system, which could supply electricity and cold storage for ‘yam bank’ within a rural community. Considering 200 households’ Nigerian village as a case study, crop residues are used as anaerobic digestion feedstock to produce biogas, which is subsequently used to power an internal combustion engine. Result shows that the system could store 3.6 tonnes of yam tubers each year and provide enough electricity for domestic and commercial activities. At the current electricity tariff of USD0.013·kWh−1 for rural areas, the system is unable to payback during its life span. The proposed USD0.42·kWh−1 by Nigerian Rural Electrification Agency seems good with less than 3 years discounted payback period but brings about extra burden on poor rural households. Based on the income from cold storage, electricity tariff of USD0.105·kWh−1 with an interest rate of 4% is suggested to be reasonable which results in 6.84 years discounted payback period especially considering non-monetary benefits of renewable energy system.

Post Harvest

This study assessed post-harvest activities and post-harvest losses of green chili farming in Kabjisa, Punakha, Bhutan. Data came from interviewing 75 chili-growers selected via proportionate random sampling. Most farmers were found selling fresh chili (green chili). Few farmers produced blanched, dried, and powdered chilies for self-consumption. Most grown chili varieties were Wookup ema, Indian chili, and Yangtsep ema. Farmers mostly harvested chilies manually during the daytime in a bucket. The majority of the farmers have sorted and graded chilies based on disease infection, damaged parts, and size. Chilies are usually packed and stored for a night before the sale. Most chili losses occurred during harvesting, followed by marketing and sorting. The price of fresh chilies had to discount significantly during the peak season as farmers could not process chilies into other products. Hence, supporting farmers with dryer, cold storage, chili value addition infrastructure, and contract farming would minimize chili losses.
