课程名称：全球后收获损失预防：基础、技术与行动者 课程概述：本课程旨在全面介绍谷物后收获损失的问题，探索全球后收获供应链的基本物理、技术和社会维度及损失预防方法。每年，约三分之一的食品生产会被损失或浪费，因此，后收获损失已成为当前全球食品安全和可持续发展的重要问题。课程包括多个关键知识领域： - 后收获损失概述 - 收获、干燥和储存等供应链活动 - 经济学与市场 - 参与者网络介绍 随着到2050年我们需要养活超过90亿人的重大挑战，粮食产量必须在使用同样自然资源的情况下翻倍。近年来，美国政府、联合国、CGIAR研究联盟等重要机构已经认识到后收获损失是影响食品安全和改善生计的一个重要机会。尽管关注度增加，但全球各利益相关者在知识、技术能力和资源方面的缺乏仍然是行动的障碍。该课程将首次为专业人士、从业者和学生提供后收获损失过程的综合介绍，并开始建立全球式的损失预防能力。 课程大纲： - 课程导览：熟悉课程内容、讲师、同学和学习环境。 - 第一周：问题：全球后收获损失：提供后收获损失（PHL）概述及其对全球食品安全和可持续性的影响，同时定义后收获供应链。 - 第二周：原因：后收获损失的主要原因与情境：介绍技术、社会和经济因素及情况，重点关注在谷物供应链中至关重要的收获、干燥和储存阶段，及其后收获损失的发生情况。 - 第三周：解决方案：后收获损失的预防框架：介绍如何预防损失的概念框架，涵盖理论、方法和案例示例。 - 第四周：行动者：全球利益相关者网络：探讨国际社会如何应对后收获损失的问题，回顾该领域的现状及其发展背景，突出台前的关键项目、倡议和方法。
Name:Course Orientation
Description:In this module, you will become familiar with the course, your instructor, your classmates, and our learning environment.
Name:Week 1: Problem: Global Postharvest Loss
Description:This module will provide you with an overview of the issue of postharvest loss (PHL) and how this impacts global food security and sustainability. It will also define the postharvest supply chain.
Name:Week 2: Causes: Major Causes & Encounters for PHL
Description:This module will introduce you to technical, social, and economic factors and situations that lead to postharvest losses. Harvesting, drying, and storage phases will be specifically covered as stages that are both vital in the grain supply chain and in which a great deal of postharvest losses are experienced.
Name:Week 3: Solutions: A Prevention Framework for PHL
Description:This module will introduce you to a conceptual framework for how losses can be prevented. Theories, methods, and case examples on prevention will be covered.
Name:Week 4: Actors: A Network of Global Stakeholders
Description:In this module you will explore how the international community is responding to the issue of postharvest loss. The module will cover the current state of the postharvest loss prevention field, as well as provide background as to how it developed. Some key projects, initiatives, and approaches will be highlighted.
This course provides an overview of the issue of postharvest loss of grains by exploring essential physical, technical, and social dimensions of postharvest supply chains and loss prevention methods globally. Each year, estimates suggest that 1/3 of all food produced is lost or wasted, making postharvest loss a critical global food security and sustainability issue of today. Key knowledge areas are presented including: -An overview of postharvest loss -Supply chain activities such as harvesting, drying, and storage -Economics and markets -An introduction to the network of actors working in this field We face the immense challenge of feeding over 9 billion people by the year 2050. To meet these demands, yields will have to more than double using the same amount of natural resources. In recent years, postharvest loss has been recognized by major institutions including the US government, the United Nations, the CGIAR Research Consortium, and several others as a significant opportunity to impact food security and improve livelihoods. Despite this increased attention, a lack of knowledge, technical capacity, and resources remain obstacles for stakeholders worldwide to act on these issues. This course will, for the first time, provide you as professionals, practitioners, and students, with a comprehensive introduction to postharvest loss processes and begin building capacity for loss prevention worldwide.
