More than 70% of low-sale family farms are operating on a profit margin of less than 10%, which signals a critical concern for the economic sustainability of limited-resourced farms. It is also important to note that most low-income farmers combine off- and on-farm income. More than 80% of low-sale farmers work off the farm, as well as 62% of their spouses (Hoppe, 2015). High tunnels (akin to greenhouses) are versatile in production location, seasonality, quantity, quality, and length of cropping season, and appear to be promising for small-scale farmer economic viability (USDA, 2022)
