National Biodiversity Assessment
The National Biodiversity Assessment (NBA) is a collaborative effort to synthesise the best available science on South Africa’s biodiversity to inform policy, support decision-making across multiple sectors, and contribute to national development priorities.
The NBA is the primary tool for monitoring and reporting on the state of biodiversity in South Africa, and is produced by the South African National Biodiversity Institute as part of its mandate under the National Environmental Management: Biodiversity Act (Act 10 of 2004), in partnership with numerous institutions and individuals.
