Detailed Solution

Overirrigation is the primary driver of land degradation in Punjab. The main reason is that over-irrigation leads to the expansion of saltiness and alkalinity in the soil. In Punjab, the significant reason for land debasement is the over-irrigation system. Over-irrigation system prompts waterlogging that thus leads to an expansion in alkalinity and saltiness in the soil.
Western Uttar Pradesh and Haryana additionally face land degradation due to the over-irrigation system. Appropriate management of afforestation can reduce the levels of degradation. Other majors like establishing cover belts of plants can have command over overgrazing, and proper removal of modern effluents and squandering after treatment can also help.
