El problema no termina en la basura: los alimentos generan hasta el 10% de las emisiones globales de gases de efecto invernadero y, cuando se descomponen sin ox\u00edgeno en rellenos sanitarios, liberan metano.<\/p>\n<p>Para Chile y Am\u00e9rica Latina, reducir este desperdicio es una pol\u00edtica clim\u00e1tica de efecto r\u00e1pido y, al mismo tiempo, una medida de seguridad alimentaria y eficiencia econ\u00f3mica. La evidencia cient\u00edfica muestra que las emisiones asociadas a p\u00e9rdidas y desperdicios atraviesan toda la cadena: producir, refrigerar, transportar y finalmente disponer alimentos que nadie consume.<\/p>\n<p>La jerarqu\u00eda importa. Primero se debe prevenir: medir descartes, ajustar compras, almacenamiento y porciones, y mejorar la coordinaci\u00f3n entre productores, comercio y consumidores. Luego corresponde rescatar y redistribuir alimentos aptos. Solo al final, los residuos inevitables deben valorizarse mediante compostaje o digesti\u00f3n anaerobia.<\/p>\n<p>La oportunidad pr\u00e1ctica es incorporar metas medibles de reducci\u00f3n en municipios, supermercados, casinos y servicios p\u00fablicos. Evitar una tonelada de desperdicio antes de que exista suele generar m\u00e1s valor que gestionar esa misma tonelada cuando ya se convirti\u00f3 en residuo. La acci\u00f3n clim\u00e1tica tambi\u00e9n comienza en la cocina.<\/p>\n<h3>Fuentes y referencias<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.unep.org\/es\/noticias-y-reportajes\/reportajes\/los-alimentos-en-descomposicion-estan-superintensificando-la\">PNUMA, 28 de septiembre de 2026<\/a><\/li>\n<li><a href=\"https:\/\/www.unep.org\/resources\/publication\/food-waste-index-report-2024\">Food Waste Index Report 2024<\/a><\/li>\n<li><a href=\"https:\/\/doi.org\/10.1038\/s43016-023-00710-3\">Nature Food (2023)<\/a><\/li>\n<li><a href=\"https:\/\/doi.org\/10.1016\/j.resconrec.2021.105562\">Resources, Conservation &amp; Recycling (2021)<\/a><\/li>\n<\/ul>\n<p><strong>Tema sugerido:<\/strong> Desperdicio alimentario, metano y econom\u00eda circular.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Por Alex Godoy-Fa\u00fandez M\u00e1s de mil millones de comidas se desperdician cada d\u00eda y el 60% del descarte ocurre en los hogares, record\u00f3 esta semana el Programa de las Naciones Unidas para el Medio Ambiente.
