Causes and Minimization of Post-Harvest Losses Course

Introduction

Food loss and waste are among the most critical challenges facing global food systems today. Post-harvest losses, in particular, occur at multiple points along the value chain from harvesting and handling to storage, transportation, and market distribution. These losses not only diminish the quantity and quality of available food but also directly reduce farmers’ incomes, increase consumer prices, and contribute to economic inefficiency and environmental degradation.

In regions where food insecurity persists, the need to reduce post-harvest losses is urgent and pressing. Vast amounts of food are lost each year due to improper handling, spoilage, pest infestations, and inadequate infrastructure. These preventable losses undermine efforts to achieve food and nutrition security, particularly in low- and middle-income countries where agricultural production is often constrained by limited resources and knowledge gaps.

This comprehensive training course is designed to explore the root causes of post-harvest losses and equip participants with practical skills and proven strategies for minimizing them. The course covers key topics such as optimal harvesting techniques, storage and packaging innovations, pest and disease management, and cold chain logistics. Through case studies and interactive discussions, participants will examine the technical, economic, and institutional factors that influence post-harvest outcomes.

By the end of the course, participants will be better prepared to design and implement context-specific interventions aimed at reducing food loss and improving supply chain efficiency. The course is ideal for agricultural extension officers, farmers, agribusiness professionals, food processors, policymakers, and development practitioners committed to enhancing food system resilience and sustainability.

Course Objectives

By the end of the course, participants will be able to:

By the end of this course, participants will be able to:

• Comprehend the fundamental concepts of food loss and waste, including their causes, types, and the broader economic, social, and environmental impacts on food systems.
• Recognize the critical role of proper harvesting, packaging, storage, and transportation in preserving food quality, reducing spoilage, and extending shelf life from farm to market.
• Analyze the influence of food management practices—such as timing, handling techniques, and environmental control—on the post-harvest condition and overall marketability of agricultural produce.
• Understand and apply food safety principles that begin in the field and extend through harvesting and post-harvest handling, ensuring that produce remains safe, clean, and suitable for consumption.
• Develop and implement strategies to minimize both physical and economic post-harvest losses, thereby improving efficiency, profitability, and food security outcomes across the supply chain.
• Select and apply appropriate post-harvest handling technologies that align with the specific requirements of different crops and are adapted to the technological capabilities and resource constraints of local contexts.
