the main causes for the land degradation in the punjab is theintensive cultivation.
land degradation causes soil errosion which further lead to drought and desertification.
Go to google images and type 'effects of land degradation' or just 'land degradation' and you should get what you want. You can also type in things like removal of topsoil & mudslides because they come under soil erosion and soil erosion. Soil erosion is a factor of land degradation. http://en.wikipedia.org/wiki/Land_degradation This website has effects of land degradation. You can also type a few of those effects in google images.
Land degradation is a process in which the value of the bio physical environment is affected by one or more combination of human-induced processes acting upon the land.

Land degradation is the land that is being degraded in some form that is negative. Soil erosion is when rock and soil is removed from one location of land to another.
Erosion, deforestation, and waterlogging are all accelerated by human actions and all lead to general land degradation. Conservation efforts to prevent land degradation include gardening, fertilizing, planting trees, and constructing wind breakers.

prevent overgrazing....
Human activity is the main cause of soil degradation. Agriculture plays a large part in soil degradation, especially clearing, irrigation, the spreading of chemical fertilizers and pesticides, overgrazing and even the passage of heavy farming equipment. Tillage and the clearing and deforestation of large plots of land also lead to soil degradation. Improper drainage in agricultural fields also contributes to soil degradation.
