Yazdani, who conserved the Ajanta and Ellora cave paintings for posterity, renovated the dilapidated Ramappa temple and it is his conservation efforts that have now fetched the world heritage tag to the Kakatiyan temple of the 13th century.
Yazdani was one of the founders of the archaeology department in the erstwhile Nizam state. The International Council on Monuments and Sites (ICOMOS) in its report to the online extended 44th session of the World Heritage Committee of UNESCO, which is currently on at Fuzhou in China, specifically makes a reference to the conservation of the temple complex by the Nizam government to state that the condition of the temple is now in a satisfactory state.
