GEOHERITAGE SITES
GEOHERITAGE SITES
What :
Geo-heritage
- Refers to the geological features
- Inherently or culturally significant
- Offers insight to earth’s evolution or history to earth science or that can be utilized for education.
IN INDIA
- The geological features and landscapes that evolved over billions of years through numerous cycles of tectonic and climate upheavals are recorded in India’s rock formations and terrains, and are part of the country’s heritage.
- FAMOUS SPOTS – the Kutch region in Gujarat has dinosaur fossils and is our version of a Jurassic Park. The Tiruchirappalli region of Tamil Nadu, originally a Mesozoic Ocean, is a store house of Cretaceous (60 million years ago) marine fossils.
BENEFITS
- Educational spaces where people acquire geological literacy
- As the climate of the future is uncertain, decision-making is difficult. Learning from the geological past, like the warmer intervals during the Miocene Epoch (23 to 5 million years ago), whose climate can be reconstructed using proxies and simulations, may serve as an analogue for future climate.
- The awareness accrued through educational activities in geo-heritage parks will help appreciate the adaptive measures to be followed for survival.
DIGNE RESOLUTION
- The importance of the shared geological heritage of our planet was first recognised in 1991 at an UNESCO-sponsored event, where Digne declaration was accepted foresaw the establishment of geo-parks as sites that commemorate unique geological features and landscapes within their assigned territories; and as spaces that educate the public on geological importance. These sites thus promote geo-tourism that generates revenue and employment.
- In the late 1990s, in what may be considered as a continuation of the Digne resolution, UNESCO facilitated efforts to create a formal programme promoting a global network of geoheritage sites. These were intended to complement the World Heritage Convention and the UNESCO Man and the Biosphere programme.
- UNESCO provided guidelines for developing national geo-parks so that they become part of the Global Geoparks Network. Today, there are 169 Global Geoparks across 44 countries.
- Countries like Vietnam and Thailand have also implemented laws to conserve their geological and natural heritage.
CONSERVATION STATUS IN INDIA
- Though the Geological Survey of India (GSI) has identified 32 sites as National Geological Monuments, there is not a single geo-park in India which is recognised by the UNESCO. This is despite the fact that India is a signatory to the establishment of UNESCO Global Geoparks. The GSI had submitted a draft legislation for geo-heritage conservation to the Ministry of Mines in 2014.
- Despite international progress in this field, the concept of geo-conservation has not found much traction in India. Many fossil-bearing sites have been destroyed in the name of development. For example, the high concentration of iridium in the geological section at Anjar, Kutch district, provides evidence for a massive meteoritic impact that caused the extinction of dinosaurs about 65 million years ago. This site was destroyed due to the laying of a new rail track in the area. Similarly, a national geological monument exhibiting a unique rock called Nepheline Syenite in Ajmer district of Rajasthan was destroyed in a road-widening project.
- The Lonar impact crater in Buldhana district of Maharashtra is an important geo-heritage site of international significance. It is under threat of destruction, although conservation work is now in progress under the High Court’s supervision.
- Unregulated stone mining activities have also contributed to this destruction. This situation calls for immediate implementation of sustainable conservation measures such as those formulated for protecting biodiversity.
- The protection of geo-heritage sites requires legislation. The Biological Diversity Act was implemented in 2002 and now there are 18 notified biosphere reserves in India. Geo-conservation should be a major guiding factor in land-use planning. A progressive legal framework is needed to support such strategies.
- In 2009, there was a half-hearted attempt to constitute a National Commission for Heritage Sites through a bill introduced in the Rajya Sabha. Though it was eventually referred to the Standing Committee, for some unstated reasons the government backtracked and the bill was withdrawn. In 2019, a group of geologists under the auspices of the Society of Earth Scientists petitioned the Prime Minister and the Ministries concerned about the need for a national conservation policy under the direct supervision of a national body committed to the protection of geo-heritage sites.
