Sustainable Cattle Ranching Project The Sustainable Cattle Ranching Project was designed to support the growth of low carbon agriculture in Colombia by gathering evidence on whether introducing Silvopastoral Systems to cattle ranching can help reduce deforestation and alleviate poverty through the increase of milk and beef production and the provision of alternative income through payments for ecosystem services. Silvopastoral Systems are agricultural techniques which improve and convert cattle grazing land into a richer environment by planting trees, shrubs, fodder crops and living fences and conserving existing forest.
