1) Conservation efforts: The establishment of national parks and protected areas has helped to conserve and protect the unique biodiversity found in the savannas. These efforts have contributed to the preservation of wildlife habitats, including those of some endangered species.
2) Sustainable agriculture: The adoption of sustainable agricultural practices has helped reduce pressure on natural resources and reduce environmental degradation. Techniques such as contour farming and crop rotation have aided in preventing soil erosion and maintaining soil fertility.
Some negative impacts of human activities on the savanna include:
1) Habitat loss: The clearing of land for agriculture, urbanization, and other human activities has resulted in the loss of natural savanna habitats. This can negatively affect the survival of many plant and animal species adapted to the savanna ecosystem.
2) Overgrazing: Unsustainable grazing practices, especially by large livestock herds, can lead to overgrazing and degradation of the savanna. Overgrazing can deplete vegetation, compact the soil, and increase the risk of soil erosion.
3) Poaching and bushmeat trade: Illegal hunting (poaching) and the trade in bushmeat pose a significant threat to savanna wildlife. Poaching endangers iconic species such as elephants, lions, and rhinos, while the bushmeat trade contributes to the decline of many other animal species.
4) Climate change: The savannas are vulnerable to the effects of climate change, including changing rainfall patterns, increased temperatures, and more frequent extreme weather events. These changes can alter plant and animal distribution, disrupt ecosystem dynamics, and affect water resources.
Addressing the negative impacts of human activities on the savanna is crucial for maintaining ecological balance and ensuring the long-term survival of both human communities and wildlife in these unique ecosystems.
