Deforestation is a major environmental concern in Assam and is caused by factors such as:

Shifting cultivation
Encroachment
Illegal logging
All of the above

The correct answer is: d) All of the above.

Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing.

Deforestation is a major environmental concern in Assam, India. The state is home to a number of important forests, including the Kaziranga National Park, which is a UNESCO World Heritage Site. However, deforestation is a serious threat to these forests.

There are a number of factors that contribute to deforestation in Assam. One of the main causes is shifting cultivation, also known as slash-and-burn agriculture. This is a traditional method of farming that involves clearing a patch of forest, burning the vegetation, and then planting crops in the ash. After a few years, the farmer moves on to a new patch of forest, leaving the old one to regenerate. However, this practice can lead to the destruction of large areas of forest.

Another major cause of deforestation in Assam is encroachment. This is the illegal occupation of forest land by people for agriculture, grazing or other purposes. Encroachment can lead to the destruction of forests and the displacement of wildlife.

Illegal logging is also a major problem in Assam. This is the logging of trees without a license or in violation of forest laws. Illegal logging can lead to the loss of valuable timber and the destruction of forests.

All of these factors are contributing to the deforestation of Assam. The state government has taken some steps to address the problem, but deforestation remains a serious threat to the environment and the economy of Assam.
