The Brazilian Cerrado, with over 200 million hectares, has approximately 28% of its area occupied by cultivated pasturelands and 39% of them are degraded. In this study, we propose a new classification of the Cerrado pastures and recommendations for sustainable intensification and savanna restoration. We propose seven classes of pastures based on the ground cover proportions of exotic grass, bare soil, and native vegetation. These lands need to be acknowledged for their biodiversity conservation and potential for sustainable intensification and restoration. In order to make ecological intensification available for the ranchers, research and technology transfer have to embrace native tree species-based silviculture, native-grass-based forage management and enhancement, and value chain of biodiversity-friendly products. The pasture management proposals of this paper are based on a concept of biodiversity as an ecosystem service, promoting local productivity and global ecosystem services.
巴西塞拉多拥有超过 2 亿公顷的土地,其中约 28%被耕种的牧场占据,而其中 39%已经退化。在本研究中,我们提出了一种新的塞拉多牧场分类方法,并为可持续集约化和稀树草原恢复提出了建议。我们根据外来草、裸土和本地植被的地面覆盖比例,提出了七种牧场类型。这些土地需要为其生物多样性保护以及可持续集约化和恢复提供依据。为了使生态集约化能够为牧场主所用,研究和技术转让必须接受以本地树种为基础的造林、以本地草为基础的饲料管理和增强以及对生物多样性友好型产品的价值链。本文提出的牧场管理建议基于生物多样性作为生态系统服务的概念,促进了本地生产力和全球生态系统服务。
