Study Notes
Land Use Pattern
- Land use pattern in India shows that more than four-fifth of the land area is used for non-agricultural purposes.
- Arable land accounts for 13.31% of the total land area, which is used for crops like wheat, maize, and rice that are replanted after each harvest.
- Permanent crops account for 4.71% of the total land area, which is used for crops like citrus, coffee, and rubber that are not replanted after each harvest.
Other Land Uses
- 98% of the land area is used for non-agricultural purposes, including land under permanent trees, fruit trees, nut trees, and woodlands.
- Built-on areas, roads, barren land, and other non-agricultural areas also fall under this category.
Impact of Human Activities
- The extent of agricultural and forest lands are decreasing rapidly due to agents of erosion like water and wind.
- The increasing number of people and their needs lead to pressure on land, resulting in land degradation.
- Human activities can lead to soil erosion, land degradation, and loss of fertile land.
