Silvopasture is more effective than other grassland techniques, Drawdown explains, because it can sequester carbon through biomass and soil. And in addition to being a key climate solution, the system can be financially fruitful for farmers. Trees and other forage can produce nuts, mushrooms, maple syrup, and other products, while providing shade and protection from the elements for livestock. And manure can serve as a natural fertilizer, at no extra cost to farmers.
