What are the positive and negative human impacts on a savanna?

Positive human impacts on a savanna may include sustainable agriculture practices that support local communities and biodiversity conservation efforts that protect the ecosystem. However, negative impacts can arise from deforestation for agricultural expansion, leading to habitat loss and fragmentation, as well as overgrazing by livestock, which can degrade the soil and reduce vegetation cover. It is crucial to balance human activities with the conservation of savanna ecosystems to ensure their long-term sustainability.
