Uttar Pradesh has 2 million hectares of degraded soil, indicating concerns for agricultural productivity.

Degradation can lead to loss of soil fertility and adversely affect crop yields.

Soil degradation is affected by factors such as deforestation, overgrazing, and improper agricultural practices.

Soil erosion, salinization, and nutrient depletion are some forms of soil degradation prevalent in Uttar Pradesh.

The state government has initiated various programs to combat soil degradation and promote sustainable farming practices.

Option B (4 million hectares) is incorrect as it overestimates the extent of degraded land in the state.
