Parag Rangnekar Highlights Goa’s Fast-Changing Ecology Through Photography

Ecologist and naturalist Parag Rangnekar has drawn attention to Goa’s rapidly changing ecology and its misunderstood landscapes, particularly the lateritic plateaus often seen as barren wastelands. Speaking at a lecture titled “Wild Goa Through the Viewfinder” at Clube Tennis de Gaspar Dias as part of the club’s centenary celebrations, Rangnekar explained that beneath the rust-red crust of these plateaus lie thriving ecosystems that host unique species of grasses, insects, and birds linking the state’s northern and southern ecological zones. He described Goa as a transitional region within the Western Ghats, holding a mix of species from both ends of the range.

Using his extensive collection of photographs, Rangnekar discussed how visual documentation helps scientists and citizens alike understand changes in biodiversity. His images reveal a decline in sightings of several endemic birds and a simultaneous increase in dry-land species like the Indian grey hornbill, suggesting potential local climate changes. He emphasized that photography can capture subtle ecological shifts, serving as both a research tool and a medium for environmental education.

Rangnekar also shared how, through photography, he and his team discovered a new dragonfly species later named Idionyx gomantakensis, first observed in 2008 and officially published in 2013. He highlighted the power of observation, recounting instances where chance wildlife encounters, when documented, contributed to scientific understanding — including what may be the world’s only photograph of a spider feeding on a bat.

Through his presentation, Rangnekar underscored that photography is not merely an art form but an essential means of recording Goa’s fast-changing natural heritage, urging people to view these landscapes not as wastelands but as vital living ecosystems worth preserving.
