Imagine the Earth as a massive, ancient book, its pages filled with the stories of oceans rising and falling, mountains being born, and entire species coming and going. Geoscience is the key that unlocks this book, allowing us to peek into the past, layer by layer. Every rock, every grain of sand, and every fossil is a clue, revealing the secrets of a world that’s constantly changing. Geologists are like detectives, piecing together the epic story of our planet, from fiery beginnings to ice ages and beyond, giving us a glimpse of Earth’s remarkable journey over billions of years.
Just as geoscience helps us unlock Earth’s ancient secrets, preserving geological sites allows us to safeguard those stories for future generations. In a move to protect and showcase India’s incredible geological history, the government has submitted 10 such sites to the Archaeological Survey of India (ASI) for consideration as UNESCO World Heritage Sites. These locations aren’t just beautiful tourist destinations, they are records of Earth's dramatic transformations. Yet, despite their importance, India currently has no geological sites under UNESCO protection.
The government’s push to secure this recognition is more than just a matter of pride. It’s about ensuring these geological wonders are preserved. India boasts around 100 geo-heritage sites, but only 32 have been declared National Geological Monuments. Sadly, without formal legal protection, many of these sites remain vulnerable to damage. This is where the Geo Heritage Sites and Geo-relics Bill, 2022, comes into play. The proposed legislation aims to safeguard these treasures, ensuring they aren’t lost to time, development, or neglect.
Take the Lonar Crater in Maharashtra, for instance, which is one of the best-preserved impact craters on the planet, formed by a meteorite that slammed into Earth at a staggering speed of 90,000 km per hour, some 35,000 to 50,000 years ago. Located in the ancient volcanic plains of the Deccan Plateau, this crater is a geological treasure, offering a window into the violent events that have shaped our planet's surface.
Then there’s Bhedaghat in Madhya Pradesh. The canyon formed by white to pink to bluish gray marbles, are the result of limestone undergoing intense heat and pressure, a process called regional metamorphism acting as a sculpted timeline, etched in stone.
Gandikota Gorge in Andhra Pradesh is yet another masterpiece of Earth's natural processes. Carved by the persistent flow of the Penner River, this canyon reveals layers of sedimentary rock, including the ancient Gandikota Quartzite.
Mines Secretary V.L. Kantha Rao has stressed that while India has 42 UNESCO World Heritage Sites, none of them are geological in nature, a gap that must be addressed. The goal is not just to achieve UNESCO recognition but also to create two fully established geoparks in the country in the coming years. These parks will promote geo-tourism, giving local economies a boost while also fostering a greater appreciation for Earth's history among visitors. Sites like those in Sikkim, which have already been acknowledged for their geological significance by the International Union of Geological Sciences (IUGS), serve as shining examples of what India has to offer.
The effort to gain UNESCO Global Geopark status is rooted in education and sustainability. By highlighting the geological importance of these sites, we’re also connecting them to the cultural histories of the regions they occupy. With proper preservation, these sites can become living museums, where Earth’s story is written into every rock and ridge. Globally, there are already 213 UNESCO Global Geoparks across 48 countries. Sadly, India has none yet, but with the push for formal recognition and protection, that could soon change. By securing UNESCO status, these sites will not only be shielded from threats but will also serve as hubs for learning and sustainable development, ensuring that the story of Earth continues to be told through these natural wonders for generations to come.
