Over-irrigation
Explanation:
The main cause of land degradation in Punjab is over-irrigation. Over-irrigation caused excess water to create water logging in the soil. This inhibits the process of germination as roots do not grow when there is stagnant water in the field. Over-irrigation increases the salinity of the soil, as the water evaporates over time, the salt is left behind on the surface of the soil.
