Postharvest Losses, Technology, And Employment by Martin Greeley Pdf
This book presents a Bangladesh case study of the farm-level postharvest system. There are two main objectives. First, to use measured estimates of food loss to test (and reject) the conventional assumptions: that postharvest farm-level food losses are large; that they can be prevented cost-effectively by technical change; and that as a consequence, there will be more food consumption by hungry people. Commonly, none of these assumptions are true and the evidence from Bangladesh, plus supporting evidence from elsewhere, is used to show why they are wrong.

How big are post-harvest losses in Ethiopia? by Minten, Bart,Engida, Ermias,Tamru, Seneshaw Pdf
Based on a unique large-scale data set on teff production and marketing, Ethiopia’s most important cash crop, we study post-harvest losses in rural-urban value chains, specifically between producers and urban retailers in the capital, Addis Ababa. We analyze the structure of the value chain and rely on self-reported losses by different value chain agents (farmers, wholesale traders, and retailers). We estimate that post-harvest losses in the most prevalent pathway in the rural-urban value chain, amount to between 2.2 and 3.3 percent of total harvested quantities. The variation in this figure depends on the storage facilities used and on assumed losses during transport at the farm. These losses are significantly lower than is commonly assumed for staple foods, possibly because of the rather good storage characteristics of teff due to its low moisture content. These findings, nonetheless, point to the need to gather further solid evidence on post-harvest losses in staple foods in these settings to ensure appropriate policies and investments
Postharvest losses and the impact of reusable plastic container technology on profitability: Evidence from tomato traders in Nigeria by Aghadi, Crystal N.,Balana, Bedru,Ogunniyi, Adebayo Pdf
Postharvest loss is a major challenge in food production and supply chains in developing countries. Using primary data from fresh tomato traders in Lagos, Nigeria, and endogenous switching econometric modelling, this study investigates the effects of reusable plastic containers (RPC) technology on traders’ net profits and the factors determining the adoption of the technology. Results indicate that the trader’s position along the supply chain, income level, seasonality, sales frequency, and technology affordability positively influence their adoption decision. We found that the use of RPC technology significantly increases traders’ net profits. The counterfactual impact analysis indicates that traders who adopted RPC would have earned 7 percent lower net profits had they not used RPC. Conversely, non-adopters would have increased their net profit by 5 percent had they adopted the technology. However, heterogenous treatment effects were observed due to heterogeneities among the adopters.
Agro-Product Processing Technology by B K Bala Pdf
Global food security is a challenging issue. Meeting the food and nutritional requirements of the world has become an issue for national policymakers and is of public concern. There is a need to enhance agricultural production, as well as, to reduce postharvest loss, improve the quality of processed products, and add value to products to make more quality food available. Agro-product processing technology plays a major role to reduce post-harvest losses, improve the quality of processed products, and add value to the products. It also generates employment and ultimately contributes to food security. Features: Covers a wide spectrum of agro-product processing technology Explains the principles and practices of agro-product processing technology with many worked examples to quickly teach the basic principles through examples Contains examples from different operations on current problems to show the wide applications of the principles of agro-product technology Includes process control and emerging technologies in agro-product processing such as energy and exergy analysis, neural network modeling, and CFD modeling This book deals with physical and thermal properties, cleaning and sorting, drying and storage, parboiling and milling, by-product utilization, heating and cooling, refrigerated cooling, and cold storage.

Post-harvest losses: Global scale, solutions, and relevance to Ghana by Ridolfi, Carlotta,Hoffman, Vivian,Baral, Siddhartha Pdf
This report collates and contextualizes available evidence on post-harvest losses (PHL) in horticultural crops in Kenya. We begin by outlining the extent of PHL in horticultural crops and its repercussions in the context of food security and poverty reduction. We then describe the growing importance of the horticulture sector in Kenya and its growth potential, especially in terms of exports. Following this discussion, we detail PHL for two important horticultural crops, mangoes and tomatoes, for which Kenya-specific evidence is available. We discuss ways to mitigate PHL from three angles: technological, economic or behavioral, and institutional. Documenting cost-effective technological interventions to mitigate PHL, we catalogue ways to tackle PHL at the individual farmer level. We then highlight behavioral bottlenecks to adoption of such technologies and the need to design interventions in ways that address these. Finally, we discuss structural and institutional changes that would need to accompany individual-level interventions to bring about significant reductions in PHL.

Tackling post harvest loss in Ghana: Cost-effectiveness of technologies by Baral, Siddhartha,Hoffmann, Vivian Pdf
Postharvest Loss (PHL) refers to measurable quality and quantity loss of food in the postharvest system. The postharvest system consists of inter-connected stages, from the act of harvest, to crop processing, storage, marketing and transportation, to the stage of consumption. PHL can occur at any stage in the postharvest chain. This note describes common types of PHL, approaches to mitigation, and the cost-effectiveness of technologies to achieve this. We begin with a section on common causes of loss, best practices for preventing these, and barriers to adoption of these practices. We then discuss prevention of loss during storage, for which several technological solutions have been developed and evaluated. Finally, we summarize the evidence on the cost-effectiveness of three such technologies that have been scientifically evaluated: hermetic storage bags, metal silos, and a cooling chamber
