Over-irrigation has a very negative effect on the environment and lead to land degradation. This is due to water logging. Due to over irrigation in Punjab the alkalinity in soil increases which makes it infertile and makes the soil unsuitable for cultivation.
The land is the largest important natural resource on which the existence of many living beings depend. The extensive use of land for different purposes has degraded its quality to a large extent. The cement industry is largely responsible for the land degradation. It produces calcite and soapstone. This creates a large quantity of dust which reduces the process of infiltration of water into the soil after it settles down on the land.
