Resumen

Aproximadamente un tercio de la comida producida para consumo humano se pierde o desperdicia. Por este motivo, las pérdidas y el despilfarro de alimentos han llegado a ser una prioridad clave en los círculos políticos internacionales. Se trata de un problema global importante que no solo amenaza la viabilidad de un sistema alimentario sostenible sino que también genera externalidades negativas desde el punto de vista medioambiental. La prevención de este terrible desperdicio tendría un impacto económico positivo sobre las economías nacionales en términos de ahorro de recursos. En este artículo vamos más allá del tradicional enfoque basado únicamente en el ahorro de recursos y cambiamos la perspectiva para explorar las consecuencias distributivas de reducir las pérdidas y los residuos alimentarios utilizando una perspectiva basada en la modelización de restricciones de recursos. El impacto debido al cambio de comportamiento de cada hogar se explica por dos factores. Uno es la cantidad de recursos ahorrados cuando tiene lugar el cambio de comportamiento, mientras que el otro está relacionado con la posición de los hogares dentro de la cadena alimentaria. Al considerar toda la cadena alimentaria en vez del enfoque habitual basado únicamente en reducir el desperdicio por parte de los consumidores, enriquecemos el conocimiento empírico sobre este problema y mejoramos la cuantificación de su impacto económico. Examinamos datos para tres países de la UE que presentan estructuras económicas diferentes (Alemania, España y Polonia) con el fin de tener una perspectiva más amplia y sólida de los resultados potenciales. Descubrimos que los efectos distributivos son distintos entre consumidores y productores y también difieren según los países. Nuestros resultados podrían ser útiles para los responsables políticos ya que indican que las políticas no deberían estar motivadas únicamente por la cantidad de desperdicio sino, en cambio, por su posición dentro de la cadena alimentaria.
