About this course: 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.
Who is this class for: No specific background is required. An interest in food security issues, sustainability, global agriculture, and international development is helpful.

I am very grateful to faculties for this course, Dr Prasantha Kalitha and his colleagues for such a informative and ultimate course on 'Global PH Losses'. This course is very important to all learners from developing and developed countries, since world's growing population facing acute food shortage, thereby saving losses becomes need of the hour.
In fact this is my first time for such online course, but enjoyed the course due to support of all the colleagues in the course.
