Indira Gandhi introduced environmental issues into India's national political agenda during her terms as prime minister from 1966-1977 and 1980-1984. This included adding Article 48A to the constitution in 1976 requiring the state to protect and improve the environment. Control over wildlife and forests was also shifted from state to concurrent jurisdiction, giving the central government more power over these issues. These changes paved the way for the creation of a federal Department of Environment in 1980, which became the Ministry of Environment and Forests in 1985 to oversee authorities like the Central Zoo Authority of India and National Biodiversity Authority of India.

2.  Indira Gandhi’s prime-ministership (1966–1977 and
 1980–1984) introduced environmental debates into the
 national political agenda. The 4th Five-Year Plan (1969–
 74), for example, proclaimed “harmonious development
 [...] on the basis of a comprehensive appraisal of environmental
 issues.” In 1976 (during the Emergency) Gandhi
 added Article 48A to the constitution stating that: “The
 State shall endeavour to protect and improve the environment
 and to safeguard the forests and wildlife of the country.”
 The same decree transferred wildlife and forests
 from state list to concurrent list of the constitution, thus
 giving the central government the power to overrule state
 decisions on that matter. Such political and constitutional
 changes prepared the groundwork for the creation of a
 federal Department of Environment in 1980, turned into
the Ministry of Environment and Forests in 1985.[1]
