The Indian National Trust for Art and Cultural Heritage (INTACH), in collaboration with the Wildlife Trust of India (WTI), and with the support of Rohini Nilekani Philanthropies hosted a one-day awareness and engagement event today at the Rangers’ College, here. This initiative is part of the broader Gaj Utsav – Gaj Lok series, which seeks to highlight the ecological and cultural significance of elephants while fostering a deeper understanding of human–elephant coexistence.
Rooted in both tangible and intangible heritage, the collaboration with INTACH brings forward narratives of oral traditions, rituals, and indigenous practices that reflect long-standing relationships between communities and elephants. A key highlight of the day was the Bala Gaja session—a bespoke engagement designed for young learners. "Bala Gaja" (meaning children and elephants) focuses on nurturing early awareness and empathy by blending conservation education with creative expression. In alignment with INTACH’s emphasis on cultural heritage, the session connects traditional art forms with contemporary conservation messaging, encouraging children to explore the human–elephant relationship through hands-on experiences.
The Bala Gaja session will feature a series of interactive workshops: Origami by Kalyani Voletti, Head of Visual Arts at Suncity School, an accomplished art educator known for her contributions to visual arts education and curated student exhibitions. Gond Art by Japani Shyam, a distinguished contemporary artist and recipient of the Rajya Hasta Shilp Puraskar, recognised for her work in preserving and evolving Gond traditions.
Clay Modelling by Ashish Verma of Nature’s Buddy, where students will create elephant forms while learning about conservation. One of the major highlights of the event was a nukkad natak (street play) performed by the community of Jim Corbett Heritage Village, Kaladhungi, who have been working on the Fatepur - Gadgadiya corridor, which effectively portrayed the issue of human–elephant conflict and the need for harmonious coexistence. The performance used powerful storytelling and local narratives to connect with the audience and convey conservation messages in an accessible format. The students were given a guided tour by Anjali Bharthari, PhD, Co-convenor, INTACH, Uttarakhand, on the diverse exhibition on elephants, showcasing their ecological importance, cultural significance, and the challenges they face in the modern landscape.
Students had the opportunity to explore the role of elephants as keystone species and their deep-rooted presence in art, mythology, and traditions. The programme also included an open mic session, “Stories for the Wild", providing students a platform to express their perspectives through poetry, storytelling, and short talks inspired by wildlife and coexistence. These activities encouraged both creativity and cultural appreciation, linking conservation with indigenous art practices said Abhishek Rawat of the Nature Buddy Society working on elephant corridor of Thano with the schools and communities. Further enriching the programme were recitation sessions and storytelling segments centred on elephants. Overall, the Bal Mela under Gaj Utsav successfully created an immersive learning environment that combined education, culture, and creativity.
By engaging students through multiple mediums, the event contributed to building awareness, empathy, and a sense of responsibility towards elephants and their conservation said Saymanti Bandyopadhyay, Manager and Head, Natural Heritage Campaigns, Wildlife Trust of India who is leading this initiative with INTACH across the country. Students from Army Public School, Birpur, Brooklyn School, MKP, LDA Junior High School, AASRA trust, Universal Academy, Green Valley Public School, Doon International, Kasiga School and Doon Presidency attended the event. Neelima Sah, AIG Forest, Regional Office, Ministry of Environment and Forest & Climate Change, felicitated the student winners of the open mic event.

Archaeological Survey of India's (ASI's) epigraphy division has decoded a 5th century CE Sanskrit inscription in Brahmi characters on a seal from Pakistan, identifying it as belonging to a Saiva temple dedicated to Svami Kotesvara at Devadaruvana, the forest of Himalayan cedar trees. ASI epigraphy wing head K Muniratnam Reddy said the inscription, incised on the seal, reads: "Devadaruvane Svami Kotesvarah." The seal was shared with ASI by Francoise Mandeville of Hong Kong.
According to the ASI epigraphy division, the seal could be regarded as the oldest inscriptional and artistic depiction of the legend of Siva roaming in the Devadaru forest as described in the Skandapurana. The finding adds to a set of Pakistan-origin inscriptions decoded by ASI epigraphy division in recent months. In 2024, the division decoded a 4th century CE Sanskrit inscription in Brahmi script from outside Gilgit in Pakistan-occupied Kashmir.
Muniratnam Reddy translated it as referring to Pushpasingha installing a Mahesvaralinga for the merit of his guru, whose name was partly lost. Around five months before the Gilgit finding, ASI had also decoded a fragmentary 10th century CE inscription on a slab found near Peshawar. Reddy said it was in Sanskrit using Sharada characters and appeared to refer to Buddhist Dharani chants, with the sixth line mentioning "Da Dha rini".

World Heritage Day 2026 was celebrated with great enthusiasm and intellectual engagement in Leh under the theme "Ancient Art, Modern Challenges: Safeguarding Petroglyphs and Shaping Tourism Circuits in Ladakh." The day-long programme was organised by the Department of Tourism & Culture, Union Territory of Ladakh, in collaboration with the Archaeological Survey of India (ASI), Mini Circle Leh, and the Himalayan Cultural Heritage Foundation (HCHF), Ladakh.
On the occasion, the Hon’ble Lieutenant Governor of Ladakh, Shri Vinai Kumar Saxena' laid the foundation stone for India's first Petroglyph Conservation Park at Sindhu Ghat, on the banks of the Indus River in Leh.
The park is envisaged as a dedicated conservation and interpretation space for Ladakh's centuries-old rock carvings (petroglyphs), many of which are facing threats from unregulated tourism, infrastructure development, climate stress, and lack of awareness. Addressing the gathering, the Lieutenant Governor described petroglyphs as "open-air museums" and "civilisations carved on stone," representing an unbroken record of human history from prehistoric times to later historic and Buddhist periods. He emphasised that the conservation of ancient heritage must be treated as an ethical responsibility and integrated into development planning.
He also highlighted Ladakh’s status as a repository of ancient heritage, hosting one of South and Central Asia’s most extensive collections of prehistoric rock art. On the occasion, the Hon’ble Lieutenant Governor of Ladakh first inaugurated the Ladakh Rock Art Photo Exhibition at The Zen Hotel, Leh, showcasing visual documentation of Ladakh’s rich prehistoric and historic rock art heritage.
