The sustainability of milpa agriculture, a traditional Mayan farming system in southern Belize, is uncertain. For centuries, the milpa has been a sustainable agriculture system. The slash-and-burn aspect of milpa farming, however, has become less reliable and less sustainable over the last 50 years due to several factors, including forest loss, climate change, population growth, and other factors. The traditional milpa practices of slash-and-mulch and soil nutrient enrichment (nutrient cycling) are agroecological practices that produce food in a more sustainable way.
