By United Nations resolution, tomorrow, Sept. 29, is officially recognized as an International Day of Awareness on Food Loss and Waste Reduction. The theme for this year’s observance is “Stop food loss and waste. For the people. For the planet.”

Given that between 30 and 40 percent of the world’s food supply goes to waste each year, the issue is a social, moral and even economic one. As the UN wrote:

Actions are required globally and locally to maximize the use of the food we produce. The introduction of technologies, innovative solutions (including e-commerce platforms for marketing, retractable mobile food processing systems), new ways of working and good practices to manage food quality and reduce food loss and waste are key to implementing this transformative change.

Reducing food loss and waste requires the attention and actions of all, from food producers, to food supply chain stakeholders, to food industries, retailers and consumers.

Reducing food waste and bringing more equity to our food system is going to take a concerted effort across the public and private sectors. But most of all, it will take effort from all of us individually to change our wasteful ways.
