In 1991, the Ministry of Environment was disestablished and its functions were merged with those of the "Ministry of Lands and Parks" to create a new ministry called the "Ministry of Environment, Lands and Parks". The successor to this ministry was the "Ministry of Water, Land and Air Protection", existing from 2001 to 2005. The successor to this was the "Ministry of Environment", existing from 2005 to 2016. Throughout all of these successive name changes and restructurings, the ministry had retained the same functional responsibilities since 1991.
