GENERAL KNOWLEDGE

Detailed explanation-1: -The impacts of intensive land use can cause compaction, erosion and the loss of soil carbon. This can reduce the biodiversity of soil, its health and productivity. Most human-caused erosion is due to pastoral farming. Soil from forestry land can also be eroded when forests are cut down and replanted.

Detailed explanation-2: -Among these, the conversion from forest to agricultural land triggers one of the most severe changes: the loss of soil organic carbon. Other impacts include the use of pesticides, which decreases soil biodiversity, intensive irrigation leading to soil salinisation, and the accumulation of heavy metals in polluted soil.
