Road bridge over the Ganga river floodplain.
The sandy floodplain is used for agriculture during the dry season. Small plantations (I don't know of what) are protected by fences made of some sort of dry grass or weed manually planted in the sand, that prevent flying sand from burying the small planted areas.
If you know the name of this type of agriculture or know what is being grown there, please post a comment!
During the rainy season (monsoon), the entire floodplain is flooded by the Ganges river.
