The Raika tribes are a nomadic people, occupying the western districts of Rajasthan and Gujurat, including the Thar Desert.  

• One estimate put their number at about 500,000, though Raikas many are abandoning the pastoralist way of life in the face of social, economic and legal pressures.  
• They are known for their Arabian camels, or dromedaries, but many Raika families raise sheep and goats.
