    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.
