Archaeologists unearth prehistoric tools in NCR's only primary forest
Mangar Bani is a Palaeolithic archaeological site and sacred grove hill forest perched next to the Mangar village on the Delhi-Haryana border. According to people aware of the matter, the tools provide clues to the daily lives of the hunter gatherer populations characterised by the occurrence of handaxes and cleavers belonging to the Acheulian (Lower Palaeolithic) cultural phase, which existed around 200,000 to 500,000 years ago. Close to 200 objects and artefacts have been found so far, they said.
HT first reported on July 14, 2021 that archaeologists have discovered cave paintings in a rocky and forested corner of Haryana, not far from the national capital, that they believe belong to the Upper Palaeolithic age.
HT reported last week that Mangar, comprising the village, and the sacred grove amid a rocky and hilly terrain, spread over 4,262 acres (of which 3,810 acres is the hill area), is among the most biodiversity rich areas of the Aravallis in the National Capital Region (NCR). The researchers have been carrying out surface exploration work in the region for a week.
Within Mangar village, Mangar Bani (677.12 acres) is NCR's most sacred grove, and possibly the only patch of primary forest in the region. It is also home to around 240 species of birds and 15 species of mammals including leopards and hyenas.
Two archaeologists from the Academy for Archaeological Heritage Research and Training (AAHRT), Sanchi, and environmentalists from Gurugram have been exploring the hilly areas and three caves in Mangar. 'We found a high number of such tools, providing enough evidence that the area is a significant archaeological site from a pre-historic point of view,' said SB Ota, former joint director general of Archaeological Survey of India (ASI) and the head of AAHRT. Ota was among the main archaeologists who discovered the Anangpur site in Faridabad in 1991, also a Palaeolithic site.
The scoping survey was conducted by a joint team from AAHRT and Centre for Ecology Development and Research (CEDAR) in and around the Mangar Bani, Mangar, Bandhwari, Shilakhri Aravallis. The team was led by Ota, along with Niharika Shrivastava, and Chetan Agarwal, senior fellows with CEDAR and Sunil Harsana, research associate CEDAR.
The team also found several cave paintings, possibly much recent compared to the tools, which depict animal and nature inspired motifs in Mangar's caves and hills.
Ota said the clues that sites in Haryana Aravallis were possible prehistoric sites first emerged in the 1990s, when certain pre-historic artefacts were found in Delhi. These were possibly transported with sand from Aravallis.
'It goes back to 1991 when I was working with the government. We were exploring the Aravallis in Anangpur. There were some reports from Delhi that these prehistoric tools were found. Sand goes from Aravallis to Delhi which is called Badarpur sand. People had reported that such artefacts found but they were not from Delhi, they came with the sand. So, we decided to explore areas from where the sand was coming. Until 1991 Aravallis were not explored. That brought us to Anangpur,' recollected Ota.
He said those artefacts were dislodged from original context. 'I came to Mangar and Damdama in December 2023 after Chetan Agarwal, a Gurugram based forest analyst, informed me about the Mangar site. We did a survey near Damdama lake and found some artefacts. These belong to the Pleistocene. Presently, we are in Holocene, which is 11,000 years old. Human culture had its beginning with lower Palaeolithic tools. In India, the culture of these tools goes back to nearly 1.7 million years. There are a few methods to date these artefacts but we are planning to use the thermoluminescence method for the tools from Mangar,' said Ota.
Thermoluminescence dating is a method in archaeology. It measures the accumulated radiation dose of the time elapsed since the material containing crystalline minerals was heated or exposed to sunlight
Ota said that metal had not been discovered during the lower Palaeolithic age. 'People were hunter gatherers. For them the hardest material was rocks. They used bones and wood also, but that may have been completely destroyed since those are organic materials. The reason we cannot find such artefacts easily near the Yamuna is because they would be buried in alluvium. One could find some in the in the Shivaliks, but the Aravallis are isolated in many ways and this area is particularly untouched,' he added.
Some archaeologists said that the documentation of such material needs to be methodical. 'We must document these pre-historic remains and the cave paintings very methodically. We as archaeologists read patterns. This area needs to be conserved because of its natural and archaeological heritage,' said Shrivastava, an archaeologist focusing on pre-historic evidence in Bastar.
'These are very important sites. Mangar and the surrounding areas are precious because they show us how very early human populations lived. They may have settled there because the atmospheric condition was conducive for people to live and we can see they had decorated their rock shelters also with paintings. Near to Mangar, Anangpur is also extremely important, the site was excavated and important artefacts such as cleavers, hand axes were found. The entire Aravallis and the Delhi ridge also have huge potential that needs to be studied. There should be no destructive activities in these areas, and mining, if any, should stop immediately,' said Nandini Bhattacharya Sahu, joint director general, ASI.
The Aravalli range is one of the oldest fold mountain systems in the world and predates the formation of the Himalayan ranges. Its current form is reduced to residual hill ranges.
The range and its surrounding area are characterised by the occurrence of various archaeological evidence, including the Acheulean culture, Mesolithic, Rock Paintings, and Chalcolithic settlements. Besides, the historical remains of varied nature include petroglyphs and early historic and medieval settlements both on the foothill area as well as on hilltops, forts, water bodies.
Though Mangar meets all criteria for a forest, it has still not been classified as one by the Haryana government. A Supreme Court verdict in the TN Godavarman Thirumulpad vs. Union of India & Others case on December 12, 1996, directed that 'forests' would not only include those understood in the dictionary sense, but also any area recorded as forest in government records irrespective of the ownership. However, the Forest (Conservation) Amendment Act, 2023, exempts 'unrecorded deemed forests' from being recognised under the modified law on forest conservation, effectively leaving areas such as Mangar Bani vulnerable.
HT reported on October 3, 2023 that the 2023 forest act will benefit real estate companies that own land in what was to be declared 'deemed forest' in Haryana's Aravallis. The revenue record for Mangar village from 1963-64 shows that the area is gair mumkin pahar (uncultivable land) and recorded as panchayat deh (owned by panchayat or common land). HT's analysis of jamabandi papers (land records) in 2023 revealed that large parts of land in Mangar and Mangar Bani are owned by real estate and other companies.
Around 1973-74, around 3,809.63 acres of land in Mangar was mutated from panchayat deh to shamlat deh (common land vested with propietors) and further subdivided for private sale. The mutation was sanctioned on the basis of an order of a sub-judge in Ballabhgarh dated March 14, 1973, according to Agrawal.
'We knew that the Aravalli forests of Mangar and surrounding villages are a key groundwater recharge zone and wildlife habitat and corridor Now this survey has revealed its rich Palaeolithic past. We hope that the area is notified for archaeological protection, and also protected as a forest,' said Agarwal.

Environment minister to visit e-waste park in Norway to note best practices
Delhi environment and industries minister Manjinder Singh Sirsa arrived in Oslo on Sunday to study electronic waste (e-waste) management systems, ahead of the city's plan to develop an e-waste park in Holambi Kalan. The visit, facilitated in coordination with the Norwegian government, will take place on Monday. Environment minister Manjinder Singh Sirsa (HT Photo) On Monday, Sirsa will visit an e-waste park in Oslo where the entire chain of e-waste management — from collection to processing — will be assessed, including technologies in use. 'We will also visit an industrial area, in the middle of the city, to again study the best practices, ranging from waste management there to ensuring recycling and zero air pollution,' Sirsa told HT. The Delhi government is planning to build a dedicated e-waste park over 11.4 acres in north Delhi, aimed at processing over 51,000 metric tonnes of e-waste annually. A feasibility study for the ₹150 crore project will be undertaken soon, following which a global RFQ-cum-RFP (Request for Qualification-cum-Request for Proposal) will be floated. 'This is a short visit to understand how Norway is managing its e-waste. We want Delhi's e-waste park to generate zero pollution. Previous governments didn't plan for the present or the future, and that is why we have waste mountains. We don't want to repeat those mistakes,' Sirsa said. He added that the Delhi government is also studying Hong Kong's e-waste management model. 'We are examining both Norway and Hong Kong to get a sense of the advanced machines and technologies we can use for the project,' Sirsa said. He is expected to return to Delhi on Tuesday. The Delhi State Industrial and Infrastructure Development Corporation (DSIIDC) is the nodal agency for the project. Sirsa, who has been accompanied by DSIIDC officials on the trip, had earlier announced that a third-party feasibility study would evaluate global models with a focus on zero-emission and zero-landfill systems. Other features under consideration include scientific dismantling protocols, metal recovery systems, digital waste tracking, air quality monitoring, and pollution control mechanisms. The park is expected to generate over ₹350 crore in economic output, according to government estimates. Once awarded, the construction of the facility will take 18 months to complete, officials have said.

Indian priest Richard D'Souza appointed director of Vatican Observatory
Indian Catholic priest Richard D'Souza has been appointed as the new director of the Vatican Observatory. The newly elected Pope Leo XIV confirmed his appointment on Thursday evening. Fr D'Souza, who has a doctorate in astronomy and who has been a staff member at the Observatory since 2016. (MLA Delilah Lobo | X account) D'Souza, 47, a Jesuit priest who hails from Goa and who holds a doctorate in Astronomy will succeed the existing head of one of the world's oldest astronomical observatories, will succeed incumbent Guy Consolmagno, when his term ends on September 15. 'I am very honoured to be appointed by Pope Leo XIV as the next Director of the Vatican Observatory,' D'Souza said in a comment to HT. Also Read:Pope to bestow one of Catholic Church's highest honors on John Henry Newman 'On one hand, I am aware of the many high-profile Jesuits who have held this position in the past and have paved the way for the Observatory's success today: I am truly standing on the shoulders of giants. On the other hand, I understand the great responsibility entrusted to me of guiding the Vatican Observatory at this critical time, so that the Specola continues to serve the Pope and the Universal Church, promoting the dialogue between faith and science, through solid scientific research,' he said. D'Souza who hails from Mapusa in Goa a Bachelor's degree in Physics at St Xavier's College Mumbai, a Master in Physics at the University of Heidelberg, Germany where he worked at the Max Planck Institute for Astronomy, Heidelberg for his thesis work; a doctorate in astronomy with research done at the Max Planck Institute for Astrophysics in Garching, Munich, concentrating on the formation and evolution of galaxies and a post-doctoral programme at the University of Michigan, Ann Arbor, US. He is a member of the International Astronomical Union and has recently had an asteroid named after him. 'I am delighted that His Holiness has chosen Fr. D'Souza to be the next director of the Vatican Observatory. I know that Fr. D'Souza has the vision and wisdom to carry the Observatory forward during this time of rapid change in astronomical research, especially given his experience with space telescopes and advanced computational techniques,' incumbent Consolmagno said. Back in Goa Richard's parents Mary and Joseph expressed their 'happiness and gratitude' at the opportunity he has been entrusted with to serve in his mission. 'As a child he was always curious and showed interest in the scientific side of things and we are happy and grateful that he has been entrusted with this responsibility that allows him to serve both his mission and the pursuit of science,' the family stated. The Vatican Observatory is one of the oldest astronomical observatories in the world. It was founded in 1891, by Pope Leo XIII. D'Souza has been a staff member of the Vatican Observatory since 2016 and has held the role of the Superior of the Jesuit community of the Vatican Observatory since 2022. In 2018, he along with researchers working at the Vatican Observatory found conclusive evidence of a long lost galaxy the third biggest after Andromeda and the Milky Way, named 32p that was 'shredded and cannibalised' by the Milky Way's galactic neighbour Andromeda about two billion years ago. This disrupted galaxy was the third-largest member of the local group of galaxies, after the Milky Way and Andromeda galaxies. Using computer models, D'Souza and Bell were able to piece together this evidence, revealing this long-lost sibling. Their findings were published in Nature Astronomy in July 2018. His research focuses on the phenomenon of galaxy merging and its effects on the present day properties of galaxies like the Milky Way. He has published in numerous international scientific journals and is a member of several international collaborations.

Real-time surveillance begins at 2 more STPs in Greater Noida
GREATER NOIDA: The Greater Noida authority has installed Online Continuous Monitoring Systems (OCMS) at two more sewage treatment plants (STPs) in Ecotech-2 and Ecotech-3 for real-time surveillance and better wastewater management and environmental compliance, officials said on Monday. The OCMS technology enables real-time tracking of key pollution parameters like Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and other indicators before and after sewage treatment. (HT Photos) The OCMS technology enables real-time tracking of key pollution parameters like Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and other indicators before and after sewage treatment, they added. 'The system was first introduced at the 2 MLD Badalpur STP, and within a month, has been extended to the 15 million litres per day (MLD) plant in Ecotech-2 and the 20 MLD plant in Ecotech-3,' said additional chief executive officer (ADCEO) Prerna Singh. To be sure, the initiative is part of the Namami Gange programme that mandates online monitoring of all STPs to ensure proper treatment of sewage and discharge of compliant effluent into water bodies. As per the central government's Namami Gange flagship programme that mandates online monitoring of all STPs, Greater Noida authority's chief executive officer NG Ravi Kumar instructed the concerned department to prioritise implementation of OCMS across all STPs in the region, Singh added. The only major STP now left without this system is a 137 MLD capacity plant at Kasna that is expected to be equipped with OCMS within a month, said officials. Meanwhile, the data collected by OCMS will be accessible not only to the authority's sewerage department but also to the Uttar Pradesh Pollution Control Board (UPPCB) and the National Mission for Clean Ganga (NMCG), who can monitor operations remotely from their offices, they said. 'We are working on a plan to equip all STPs with online monitoring systems and Kasna STP is next. The move will help ensure improved operations and quality control,' she added. The system enables up to six users—officials from the authority, contractors, UPPCB, and Namami Gange officials—to access real-time data through laptops or mobile devices. The estimated cost of installing OCMS at each STP is around ₹30 lakh, fully borne by the authority, said senior manager (sewerage department, Greater Noida authority) Vinod Sharma. Beyond compliance, the authority is also exploring the utility of treated water. Currently, the water obtained after treatment is used for irrigation and construction purposes. Officials said that talks are underway between the authority and National Thermal Power Corporation to use this water for thermal power generation as well. Officials said that citizens or contractors interested in using treated water for irrigation or construction can obtain it at a nominal rate of ₹7 per kilolitre by contacting the sewerage department on 9211825118. The initiative comes as part of Greater Noida authority's broader strategy to modernise wastewater treatment infrastructure. The authority is working to transition to advanced technologies to enhance treatment efficiency and meet stricter discharge norms, HT had reported on July 26. The integration of OCMS is viewed as a complementary step towards ensuring transparency, accountability, and long-term sustainability in sewage management, officials said.
