The Central Zoo Authority of India (CZA) is the body of the government of India responsible for oversight of zoos. It is an affiliate member of the World Association of Zoos and Aquariums (WAZA). The CZA was formed to bring Indian zoos up to international standards. Before the CZA was formed, many zoos were poorly managed, with unsuitable animal enclosures and little or no breeding records of animals, which caused inbreeding and hybridization (genetic pollution, as in one case where an Asiatic lion were cross-bred with an African lion).
