The correct answer is (a) Etawah.
Gully erosion is a type of soil erosion that occurs when water flows over the land and creates channels or gullies. These gullies can become deeper and wider over time, and they can eventually destroy land that is used for agriculture or other purposes.
Etawah is a district in Uttar Pradesh, India, that is located in the central part of the state. The district is known for its fertile land and its production of wheat, rice, and sugarcane. However, Etawah is also one of the most affected districts in Uttar Pradesh by gully erosion.
The main causes of gully erosion in Etawah are deforestation, overgrazing, and poor agricultural practices. Deforestation removes trees and other vegetation that help to hold the soil in place. Overgrazing can also damage the soil and make it more susceptible to erosion. Poor agricultural practices, such as plowing in the wrong direction, can also lead to gully erosion.
The effects of gully erosion in Etawah are significant. Gullies can destroy land that is used for agriculture, and they can also damage roads and other infrastructure. Gullies can also make it difficult for people to travel and access basic services.
The government of Uttar Pradesh has taken some steps to address the problem of gully erosion in Etawah. These steps include planting trees, fencing off areas that are prone to erosion, and providing training to farmers on how to reduce soil erosion. However, more needs to be done to address this problem.
The other options are incorrect because they are not districts in Uttar Pradesh.
