Duration: 1:55 hours
Abstract:
Post-harvest food losses remain very high in developing countries, estimated at about 50% on average for perishable produce, despite the resolution of the United Nations General Assembly in New York in 1975 calling for at least a 50% reduction by 1985, which was not attained in most developing countries. Small, resource-poor farmers account for the bulk of food production in developing countries and high post-harvest food losses discourage production, impoverish farmers, reduce food availability, promote food insecurity and constrain rural development. Improper harvesting and post-harvest handling practices, poor infrastructure, lack of efficient food storage and processing facilities, weak supply chains, and lack of information that limit access to local, regional and international markets for smallholder farmers contribute to high post-harvest food losses in developing countries. Education, capacity building, improved harvesting and post-harvest handling practices, better infrastructure, the use of digital technology to improve market access for smallholder farmers, village level processing, empowering women who are largely responsible for most food processing activities, and other practical and workable systems and strategies for reducing post-harvest food losses in developing countries are discussed.
This webinar is hosted by the GHI Reducing Post-Harvest Losses Working Group. The Groups overall mission is to identify technologies and procedures to reduce food loss and food waste around the globe, and to identify those technologies and procedures that are appropriate to be proposed for harmonized regulations.
This GHI webinar and interactive sessions, will be chaired by Dr. Diana Bogueva, Director of GHI Working Groups
Reducing post-harvest losses in fresh produce in developing tropical countries with special reference to Sub-Saharan Africa
Dr. Ogugua Charles Aworh is a Board Director of the Global Harmonization Initiative and a Retired George Coumantaros Distinguished Professor, Department of Food Technology, University of Ibadan, Nigeria
Abstract:
The tropical environment characterized by high temperature and humidity, and a high incidence of pests and diseases aggravates post-harvest losses of fruits and vegetables on account of their high moisture content, high rate of metabolic activities including respiration, and soft tissue that predispose them to physical damage (abrasions, cuts, bruises, deformation, invisible wounds), biological damage caused by bacteria, fungi and insects, and physiological damage due to changes caused by respiration, ripening, senescence and sprouting that impair quality, cause spoilage and limit their post-harvest life. Post-harvest losses in fresh produce in developing tropical countries, where small, resource-poor farmers account for the bulk of food production, is estimated at about 50% on average, but could be much higher, depending on the circumstances, as they are time dependent and location specific. High post-harvest food losses in developing countries is detrimental to food production, livelihoods, food security and rural development. This presentation highlights workable, practical strategies, intervention measures and appropriate technologies for reducing post-harvest losses in tropical and sub-tropical fruits and vegetables in developing countries with special reference to sub-Saharan Africa including advocacy, education and capacity building; adoption of good agricultural practices, good hygienic practices, improved harvesting methods, improved post-harvest handling practices and market preparatory or packinghouse operations; provision of improved infrastructure, transport and market conditions; strengthening supply chains and the use of digital technology to bridge information gap and improve market access for smallholder farmers.
Enterprise Skills Development in Village Level Food Processing for Food Security and Accessibility for all
Dr. Alastair Hicks is an elected Life Fellow of the International Academy of Food Science and Technology FIAFoST, for which he was Councilor of the Academy Executive Committee AEC.
Abstract:
This talk discusses an initiative in rural enterprise development and crop diversification activities specifically in the CLMV region – Cambodia, Laos, Myanmar, and Vietnam. The objective is to promote enterprise skills development in village level food processing, and to provide food security and accessibility for all, through poverty reduction and empowerment of vulnerable groups. The approach consists of the following steps:
• Training national focal persons to then train villagers in small-scale food processing activities, with skills needed to stimulate and sustain rural enterprises.
• Applying food science and technology to add value to crops postharvest, upgrading traditional food products to enter local then regional markets including tourism.
• Developing safe, hygienic practices for traditional food products, extending their shelf life with improved suitable packaging and supply chains.
• Establishing provincial and national food pilot plants to train food enterprise operators and villagers in the above, through Success Case Replication.
The challenges, activities, outcomes and next steps will be outlined during this presentation.
Comprehensive plan to reduce post harvest food loss and waste
Dr. Kenneth Marsh is Chair of the GHI Post-Harvest Losses working group and Executive Director of the Woodstock Institute for Science & the Humanities in Clemson, South Carolina, US, a not-for-profit organization working to reduce world hunger by cutting food losses.
Abstract:
Global food production is sufficient to feed everyone on earth but a significant portion of food is lost at every stage of production and after harvest. The presenter estimates that recovering 20% of current losses would yield sufficient food to feed everyone if political will was sufficient to do so. This seminar presents a comprehensive approach to reducing food loss that includes the more detailed approaches already presented by Drs. Aworh and Hicks that apply to the developing world and adds approaches to reducing food waste primarily in so-called developed countries. The comprehensive plan includes reducing food losses through international cooperation, infrastructure investment and development, Village Level Food Processing, harmonizing food regulations (GHI), building political will and reducing food waste.
