The demand was made by Chief Minister Naveen Patnaik in a letter to Union Women and Child Development Minister Krishna Tirath.
Seven children, including three girls, had died on July 9 due to a wall collapse at an Anganwadi centre run from the campus of an upper primary school at Suansia village in Ranpur area in the district.
"I urge upon you to allocate sufficient funds for construction of nearly 50,000 AWCs in the state so that children are protected and the aims and objective of the Integrated Child Development Scheme (ICDS) are met fully," Patnaik said in the letter.
He said out of nearly 71,000 Anganwadi centres in the state, only about 20,000 have their own buildings and rest are run either in school buildings or in rented houses which are not always appropriate for running them and also posed a "serious hazard."
