Reduce Food Waste by Gleaning Green
Gleaning Green: Food for Free
by Ari Levaux
The voice on the phone gave me directions to a house in a residential neighborhood. The way she spoke made me feel vaguely like James Bond receiving an assignment from “M.” “The owners gave permission for the tree to be picked, but they don’t get home from work until two. Before then, don’t even knock on the door because they have two yipper dogs who will go crazy.” she explained. “The tree is really tall; I think it might be grafted, which means the upper cherries could be better than the lower ones, so if you have a ladder you should bring it. In this heat they aren’t going to last long so you should go soon. Do you think you can go today?”
According to the UN Food and Agriculture Organization, 33 percent of the food grown worldwide goes to waste. Valued at 750 billion dollars, it would take a farm the size of Mexico to produce this amount of wasted food. And when it rots in a landfill, the UNFAO estimates that the gases that are created account for 6-10% of the greenhouse gases released into the atmosphere. If global food waste were a country, Grist.org reports, it would be the third largest emitter of greenhouse gases.
In the face of a growing population, much attention has been paid to various ways of producing more food, usually via modern agricultural techniques. A less sexy approach to feeding the hungry, while simultaneously cutting down on greenhouse gas emissions, would be to reduce the amount of food that is wasted.
Enter the gleaners.
The act of gleaning, as it relates to food, is to salvage food that would have gone un-harvested. It’s an act as old as agriculture. The ancient poor used to prowl the harvested fields of rich landowners and pick the grains or vegetables left behind. Today in the world’s poorest countries, gleaning still occurs in much the same way, while in wealthier nations like the U.S., gleaning takes on myriad modern forms.
In cities around the US, activist groups have forged relationships with grocers, caterers, restaurants, and growers at the supply end, and with food pantries, homeless shelters, and other organizations feeding the hungry at the demand end. Many of these organizations, such as Food Shift in the Bay Area, consider reducing greenhouse gas emissions to be an essential part of their missions—along with feeding those in need.
And then there are rogue gleaners like myself, working in cahoots with the likes of the woman who told me about the cherry tree, or alone. Beginning in mid-summer, it’s easy to walk the residential streets and alleyways looking for trees from which ripe fruit is dropping to the ground. All it takes is a knock on the door to determine if the homeowner would be open to you picking the fruit. I usually offer to pick up the rotten fruit that has already fallen as well, in exchange for harvesting the potential mess that’s still dangling from the trees.
Then, if everything goes according to plan, I have a lot of fruit on my hands, which must be dealt with very soon. It can be frozen, whole or juiced, or turned into jam, or dehydrated—my method of choice.
Later in the season I’ll turn my attention to fall vegetables, like kale, which gets sweeter after a frost. The freeze is usually beginning just as the farmers markets are ending, and farmers are ready to turn their fields under for the year. During the last few markets of the season, I’ll strike deals with growers to acquire large amounts of their kale before it meets the plough.
Sometimes the grower will invite me to come glean it myself, old-school style. But more often they’ll offer to harvest a massive amount and sell it to me at a bargain rate. Technically speaking, food that’s acquired in this manner isn’t “gleaned,” but “recovered.” Either way, it’s food that wasn’t wasted, that by filling bellies puts less demand on a carbon-intensive, land-hungry food system.
And for those who don’t have an associate like the woman who guided me to the cherry tree, a smart phone can make a good substitute. A new organization called Falling Fruit (Fallingfruit.org) is building a worldwide database of urban edibles, including, according to a video on the site, “Apples, apricots, mangoes, plums, avocados, star fruit, citrus, nuts, berries, vegetables, spices, herbs [and] mushrooms.” A smart phone app is under development, soon to be released.
I loaded the map onto my laptop and took a look. It showed, within blocks of my house, apples, apricots, plums, peaches, and grapes. So I took a walk, and there they were. There was also a nice gooseberry bush. Many trees were hanging over fences above the sidewalk. There were no mangoes to be scrounged, but I pigged out nonetheless.
