The two-week long yatra, that begins from North Karnataka, will make its way though 25 districts of Telangana, Maharashtra, Madhya Pradesh, Uttar Pradesh, Rajasthan and Haryana.
It seeks to understand and highlight the alternative models of dealing with the drought, the group said describing the yatra as an attempt to draw public attention towards a looming "national disaster".
It will be comprised of a team of 10-15 activists, writers, artists, journalists and noted photographers such as Raghu Rai and Dayanita Singh.
At its end on October 15, SA will hold a public hearing involving "leading voices" of the country from various walks of life. "For this, we first need the country to know about the extent and dimension of this crisis. The conscience of the country needs to be touched, awakened," it said.
