The long-term availability of food is essential to guaranty human existence. Therefore, relevant stakeholders, the government, and society are increasingly concerned about public food procurement in the most sustainable manner where distance and cultural characteristics are considered. While short food supply chains (SFSC) are essential, little is known about the relevance, magnitude, and policy lesson within a developing country context.

Food Chains: Quality, Safety and Efficiency in a Challenging World addresses the many issues facing European food producers and other food chain stakeholders, who endeavour to improve their competitive position in a highly competitive world food market. The Food Chain is one of the main economic pillars in Europe, providing employment and opportunities for economic development in rural areas. It is therefore imperative to continuously monitor the changes that affect the sector, in order to allow stakeholders to respond promptly and effectively to the new market conditions. Adjusting to the new

Food waste is the loss of perfectly edible food products. It is a wide-ranging phenomenon: a substantial part of agricultural production is never consumed. The prevalent, most widespread paradigm regarding this phenomenon holds that it is due to inadequate logistics and technology, or to poor management of food on the part of end users. However, an analysis from a political ecology standpoint allows a different interpretation: the root of the problem lies in the hegemonic agrofood system and the unequal power relationships between the actors in the agrofood chain. ; This research was supported by Ministry of Higher Education, Science, Technology and Innovation (Secretaría de Educación Superior, Ciencia, Tecnología e Innovación – SENESCYT) of the Republic of Ecuador (Prometheus Project).

C'est un phénomène de grande dimension: une partie substantielle de la production agricole mondiale n'est pas consommée. Le paradigme dominant et le plus répandu sur ce phénomène considère qu'il est dû à des insuffisances logistiques et technologiques, ou à la mauvaise gestion de la nourriture par le consommateur final. Cependant, une analyse de l'écologie politique permet une lecture différente: la racine du problème est dans le modèle agroalimentaire hégémonique, et dans les relations de pouvoir inégales qui existent entre les acteurs qui composent la chaîne agroalimentaire. ; [spa] El desperdicio alimentario es la pérdida de los alimentos producidos y perfectamente comestibles. Se trata de un fenómeno de grandes dimensiones: una parte sustancial de la producción agraria mundial no llega a ser consumida. El paradigma dominante y más difundido sobre este fenómeno considera que se debe a insuficiencias logísticas y tecnológicas, o a la mala gestión de los alimentos por parte del consumidor final. Sin embargo, un análisis desde la Ecología Política permite una lectura diferente: la raíz del problema está en el modelo agroalimentario hegemónico, y en las desiguales relaciones de poder que existen entre los actores que conforman la cadena agroalimentaria
