Definition of Food Consumption, Loss, and Waste

Abstract

The global food system has three recognized challenges: (a) increasing the availability of food for consumption; (b) reducing food loss; and (c) reducing food waste. The increasing demand for food for consumption, the increasing quantity of food loss, and the corresponding increase in food waste are resulting in serious health, aesthetic, social, economic, and environmental problems due to a lack of appropriate planning and management. Despite its importance, there is no clear, concise, and comprehensive definition of food consumption, loss, and waste. Generally, food consumption, food loss, and food waste are dealt with separately. This article presents a logically constructed ontological framework of food consumption, loss, and waste. It gives equal importance to all three aspects of global food management. The systemic ontological framework is general, and the analysis can be applied to any country. The framework deconstructs the combinatorial complexity of the problem and explicates the pathways to manage the consumption, loss, and waste. The ontological framework encapsulates 19 × 11 × 7 × 4 × 6 = 35,112 possible components of the challenge. A critical analysis based on available data using the framework will help to develop strategies to deal with the problem. It can help us to discover the gaps and to find ways to bridge the gaps. It is a novel way to conceptualize food consumption, loss, and waste together.
