Four billion trees died in what is often considered one of the worst ecological disasters in modern times. When many east coasters hear chestnuts, they might think about the American chestnut, a storied tree that dominated American forests and cityscapes until it was killed off by blight in the 20th century. The institute recently released a report saying that the “broad adoption of chestnuts could also help ‘flip the script’ on agriculture’s role in climate change”. And the Savanna Institute urges landowners to consider a variety of perennial nuts – especially the chestnut. Further south, the University of Missouri Extension School is researching best practices for planting and selling black walnuts. In Wisconsin, hazelnuts are taking off thanks to the Upper Midwest Hazelnut Development Initiative, a non-profit that encourages growers to plant, harvest and sell hazelnuts. “If we were to think about how to radically change agriculture, one of the ways we would do that is to eliminate tillage agriculture by planting trees that do the same function,” said Eliza Greenman, a germplasm specialist at the Savanna Institute, a non-profit that promotes planting trees on farmland in the midwest.

His project is part of a surge of interest among food activists, academics and farmers in using nut trees to replace large-scale forms of agriculture and food sources, which dominate billions of acres of land globally and produce 11% of US greenhouse gas emissions. Judd, who organizes his efforts through the non-profit SilvoCulture, which he helps to run, is not alone in his enthusiasm for chestnuts. Planting one, Judd said, means “you’ve got a real valuable, storable, nutrient-rich food you can rely on annually”. As a source of protein and carbohydrates, the chestnut – nicknamed “the bread tree” – can provide food security for communities.Īnd they can be a boon for farmers: once chestnut trees mature, they can produce 50 to 100lb of nuts per tree annually, retailing from $3 to $16 per pound. It grows easily in a variety of environments, from Maine to Florida. The chestnut is a perennial crop, meaning it doesn’t have to be replanted every year, so it’s a better moneymaker than the annual monocultural agricultural system that dominates so much of the American landscape. Judd bought this six-decade-old orchard to conduct experiments in service of his grander mission: to help plant 1m nut trees across the US’s mid-Atlantic region, chief among them the chestnut.įor Judd, the chestnut is a solution to environmental and economic problems facing the area.
