A dense giant component was detected that spanned 73 percent of the network with a density of 0.0017 and clustering coefficient of 0.631, suggesting high level of knowledge diffusion and a rapid flow of information and creativity in this network. Local metrics were calculated using degree, betweenness and closeness centralities. A strong correlation was seen between degree and author productivity (number of works) and betweenness centrality and author productivity, suggesting that author's number of connections and controlling \u201cin-between\u201d position in the network may be providing the authors\u2019 with the knowledge and resources to be more productive. <\/jats:p>\n            <\/jats:sec>\n            <jats:sec>\n               <jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title>\n               <jats:p> \u2013 The impact of human actions on the earth systems is a hot topic of research in India.
