FAO // How Access to Energy Can Influence Food Losses
By Manas Puri. The report begins by reviewing the evidence to date focussing on the magnitude and geographical distribution of food losses. In the next sections the role of energy in post-harvest losses is discussed. Thereafter, the main entry points within the food value chain where lack of access to energy is the dominant factor influencing food losses is discussed. This report outlines low cost and off-grid post-harvest cooling and processing technologies that can be made available in developing countries.
These household to community scale evaporative cooling systems, solar assisted cooling systems and as well as solar drying systems that can help increase shelf life . Additionally, through case studies, focus is laid on assessing the technical and economic feasibility of cooling and processing technologies. Finally, recommendations are made that could be incorporated to further develop food loss strategies that can classify food value chains based on their energy demand. This will enable policy makers to quickly understand the main technologies for food preservation and processing that can be introduced based on the available energy sources in a given region.
