‘Climate change may lead to faster deterioration of rock art sites in the Nilgiris’

Rock art sites in Nilgiris vulnerable to climate change, necessitating long-term monitoring for protection. Iduhatty rock art site has 30 abstract signs/figures. Research from UNC suggests warm/humid weather accelerates weathering. Monitoring programme initiated at Iduhatty, but more support needed. Documenting sites through photos recommended to preserve art.
Climate change could lead to faster deterioration of rock art sites in the Nilgiris, necessitating long-term monitoring of the sites to protect them from disappearing, according to researchers working on documenting rock art sites in the Nilgiris.
Using the rock art site at Iduhatty as an example, Janardhan Nanjudan, a researcher and an ecologist from the Nilgiris, said “the exceptionally old rock art of Iduhatty is located within a dynamic sub-tropical environment that renders it particularly vulnerable to the destructive impacts of climate change, adding unique urgency to this call for further research and protection,” he said.
According to other researchers documenting rock art sites in the Nilgiris, there were over 10 such sights recorded in the recent past, including the most spectacular of the sites – the Karikiyoor rock paintings.
The rock art site in Iduhatty has over 30 abstract signs and figures – dots, circles, cordiform, lines, quadrangle and wired diagrams. Mr. Nanjudan argues that climate fluctuations in recent decades could become a major factor for the deterioration of the rock art sites in the district.
Pointing to recent research from the University of North Carolina, he stated that “warm and humid weather could accelerate the weathering of the surfaces on which the rock art is found.
“Understanding the environmental impacts to early rock art sites is crucial for designing effective management strategies to help preserve these irreplaceable images from the human past. A long term physical and chemical monitoring is required. While a small-scale monitoring programme has recently been initiated at Iduhatty rock art site by Muddy Boots Nilgiris supported by Green Mount India Foundation, more support for this initiative is required, especially in terms of investment for equipment,” he said.
Another researcher, who has visited rock art sites in the Nilgiris over the last decade, said that the gradual weathering of the art sites was a concern, but added that he was not sure if climate change was as yet having a significant impact on accelerating weathering of the rock art sites. “Many of the rock art sites in the Nilgiris are exposed to the elements, and have always been at risk of being lost due to weathering. It would be prudent to document these areas thoroughly through photographs, with teams of archeologists, so that even if the actual sites themselves are lost, then at least there would be digital records of the art at these sites,” he said, requesting anonymity.
“We are judges and therefore, cannot act like Mughals of a bygone era ... the writ courts in the guise of doing justice cannot transcend the barriers of law,” the High Court of Karnataka observed while setting aside an order of a single judge, who in 2016 had extended the lease of a public premises allotted to a physically challenged person to 20 years contrary to 12-year period stipulated in the law.
The High Court of Karnataka on Monday declined to interfere, at present, in the investigation against a Bharatiya Janata Party worker, who is among the accused persons facing charges of circulating obscene clips, related to “morphed” images and videos clips related to Prajwal Revanna, former Hassan MP, in public domain through pen drives and other modes.
The 16th edition of Bhoomi Habba was held on June 8, at the Visthar campus. The festival drew a vibrant crowd who came together to celebrate eco-consciousness through a variety of engaging activities, creative workshops, panel discussions, interactive exhibits and performances, all centered around this year’s theme: “Save Water, Save Lives.”
