Study Notes
Consequences of Desertification on Biodiversity
- Soil erosion and loss of vegetation contribute to biodiversity loss due to desertification
- Desertification leads to habitat loss and fragmentation, causing population decline and extinction
Primary Drivers of Desertification
- Overgrazing and land degradation are primary drivers of desertification, contributing to biodiversity loss
Human Activities Exacerbating Desertification
- Overcultivation and deforestation are human activities that exacerbate desertification, leading to biodiversity loss
Consequences of Biodiversity Loss due to Desertification
- Decreased ecosystem services, such as pollination and pest control, are consequences of biodiversity loss due to desertification
- Loss of genetic diversity reduces the ability of ecosystems to adapt to changing environmental conditions
Feedback Loop between Desertification and Biodiversity Loss
- Decreased vegetation cover and biodiversity can lead to increased soil erosion and desertification, creating a feedback loop
- This feedback loop can accelerate biodiversity loss and desertification, making it more challenging to restore ecosystems
