Introduction

Post-harvest loss (PHL) in perishable crops represents a significant challenge to global food systems. Substantial quantities of fruits, vegetables, and other perishables are lost between harvest and consumption due to a variety of factors, including inadequate harvesting practices, improper handling and storage, inefficient transportation, and poor marketing infrastructure. These losses not only diminish food availability but also impact farmer livelihoods, environmental sustainability, and economic development. This training course is designed to address this critical issue by equipping participants with the knowledge and skills necessary to implement effective post-harvest loss reduction strategies. The course will cover the entire post-harvest value chain, from pre-harvest management to consumer access, providing a holistic perspective on PHL and its mitigation. Emphasis will be placed on practical, evidence-based solutions that are both sustainable and economically viable, enabling participants to make a tangible impact in their respective contexts. The program aims to foster a community of practitioners dedicated to reducing PHL and improving food security for all.
