Study Notes
Land Degradation
- Land degradation refers to the decline in the quality of land, resulting in reduced productivity and decreased ecosystem services.
Contributing Factors
- Natural factors, such as climate change, drought, and soil erosion, contribute to land degradation.
- Human activities, including deforestation, overgrazing, and unsustainable agricultural practices, also contribute to land degradation.
Human-Induced Land Degradation
- Human actions, such as the clearing of land for agriculture, urbanization, and infrastructure development, lead to land degradation.
- The extraction of natural resources, such as mining and drilling, can also result in land degradation.
Impact on Productivity
- Land degradation results in reduced fertility and productivity of soil, leading to decreased crop yields and lower agricultural productivity.
- It can also lead to the loss of biodiversity and ecosystem disruption.
Global Implications
- Land degradation is a worldwide issue, affecting approximately one-third of the global land area.
- Its impacts are felt globally, with consequences for food security, water availability, and human settlements.
- Land degradation affects not only local ecosystems but also has far-reaching implications for the environment, economy, and human well-being.
