His first major political assignment was as an adviser to then Madhya Pradesh chief minister Uma Bharti in 2004.He then went into political oblivion for sometime as Bharti was replaced by Shivraj Singh Chouhan. But, then he started working on environment related issues on Narmada in Madhya Pradesh and Gujarat and was nominated to the Rajya Sabha in 2009.Those close to him said Modi was impressed with his organisation of a seminar on Hinduism and rivers at an event during 2015 Ujjain Kumbh.Experts from across the world attended the three-day conference inaugurated by the PM. A few months later, he was nominated as environment minister, replacing Prakash Javadekar.From the start, the minister had shown his disdain for civil society activists and had told the HT that “he will not talk with those who give speeches sitting in air-conditioned offices”.He had also rubbished a Health Effects Institute study that said that 1.1 million Indians died because of air pollution in 2015 and requested the health ministry to conduct study on impact of air pollution.As environment minister, Dave had fastened approval of India’s first river-linking project Ken-Betwa falling in Uttar Pradesh and Madhya Pradesh.On Wednesday, the Forest Advisory Committee (FAC) gave its conditional principle approval to the project that will submerge one-third of Panna tiger reserve in Madhya Pradesh and will irrigate 6.35 lakh hectares of land in drought- prone Bundelkhand.Dave took several policy initiatives, including delegating power to give environment clearance to building projects to the state governments and time-bound approval to projects.He pushed approval for genetically modified Mustard which was stalled for the last two years. The Genetic Engineering Appraisal Committee (GEAC) last week recommended to the government its commercial release.
