Panaji: Investing in tunnelling technology, especially carving out tunnels under water as well as in treacherous terrain like the Western Ghats and the Himalayan range, can boost the Make in India mission, according to a top railway official.
It would save the country a lot of foreign exchange and will dovetail into Prime Minister Narendra Modi’s ‘Make in India’ vision, the top Konkan Railway (KR) official told IANS.
Repairs of the tunnels along the KR track could only be fully undertaken after track doubling, said B.P. Tayal, the Konkan Railway’s chairman and managing director, shortly after Railway Minister Suresh Prabhu formally announced the setting up of the George Fernandes Institute of Tunnel Technology in Margao, in South Goa.
Stating that tunneling expertise has to be developed, Tayal said: “At present whatever doubling we are doing in Jammu and Kashmir, it is designed and supervised by foreigners for us. We are losing a lot of foreign exchange in that and they are not passing the knowledge to us.
The Tunnel Technology institute, being started in partnership with the Goa University, will promote education and research in tunnelling technology, which the country would desperately need for creating connectivity to India’s remotest regions, the official said.
“We need tunnelling technology in the years to come. We would need technology like this and centres of excellence, which would further such technology,” Tayal said, adding underwater tunnelling technology could also be a key area of research and application in the coming years.
Asked whether indigenous tunnelling technology would dovetail into Modi’s vision of Make in India, he said: “Make in India will save a lot of foreign currency. We will have expertise.”
Once considered unfeasible because of the treacherous, loose-soiled and hilly Western Ghats terrain, which it was meant to snake through, the Konkan Railway route now boasts of 91 tunnels and over 2,000 bridges stretching over 736 km starting from Roha terminus in Maharashtra and to Thokur in Karnataka.
The expertise gained by KR’s engineers in tunnelling technology has enabled the Konkan Railway Corporation Limited to pitch and successfully execute railway as well as road tunnelling and bridge construction contracts in India as well as abroad.
KR is currently engaged in constructing tunnels as well as prestigious projects like the bridge over the Chenab river – the highest bridge in the country – in Jammu and Kashmir.
Speaking about the challenges of doubling the Konkan Railway track and carving out dozens of tunnels all over again on the 736-km-long track, Tayal said: “We had constructed these tunnels in the 1990s. Now we are far ahead in technology and expertise. We know what kind of rocks are there in one tunnel. All we need to do is to start on new tunnels 50 metres away from the present ones”.
“We will use technology which will cause least damage to environment. We have already undertaken a lot of plantation,” he said.
The challenges in drilling tunnels through the Western Ghats were enormous, he said, adding that the cost of construction often ranged between Rs.50 crore and Rs.100 crore per km.
“The tunnels at Pernem, Old Goa and Barcem are the most difficult tunnels on the Konkan Railway route he said, blaming loose soil and ecological risks as major issues.
“We are still struggling with these three tunnels, because you cannot close down the (single) line. But this can be taken care of when we do the doubling, the official added.
Great historic events that have shaped the world and changed the outlines of countries are often not recorded in memory, or so we think. Wars made sure to destroy evidence and heritage, and the ones who survived told the tale of what really happened. Folklore, albeit through oral tradition kept alive many such stories, hidden in verse, limericks, and rhymes.
Ringa-ringa-roses, a common playtime rhyme among children across the world, is an example of folklore that has survived for many centuries. It tells the story of the The Great Plague of London which ravaged the city between 1665-1666.
The Plague broke out from improper disposal of garbage and poor sewage conditions. Fleas from the rats that lived in the sewers spread the disease that killed more than half of London's population. Many people fled from their homes as there was no medicine available for those who were infected.

It was around this time that masks began to be invented. The first masks were shaped like beaks, and were worn not to protect the wearer from the disease, but to the prevent them from being able to smell the decay and death around them, which they called 'miasma'. The beaks were filled with floral herbs that allowed doctors and nurses to tend to the sick without being reviled from the smell.
Children are often seen forming circles by holding hands and reciting loudly,
Pockets full of posies
We all fall down"

When the last line is sung, they break the circle and fall down. The roses and posies are believed to be the preferred fragrances inside the masks, and a single sneeze (a-tishoo) was enough to infect the one who was exposed to the disease. Consequently, they fell down, ill, and later died.
An alternative version of this rhyme is sung about the fall of Hiroshima and Nagasaki in the aftermath of World War II. The roses and posies are interchanged with geranium and uranium, to symbolise what was used in the atomic bomb. But this version is not as famous the original.

In modern times, many social movements aim to bring reform to the society we live in, on the basis of certain existing patterns. Patriarchy is something that many aim to cleanse our cultures of, to usher in the era of social and gender equality. Despite all these so-called movements, in southern India, certain societies that patronise matriarchy have existed since before India's independence. The Nairs and Ezhavas of Kerala, and Bunts and Billavas of Karnataka are matrilineal societies that continue to thrive in a patriarchal country.
Kerala remains separate from the rest of India in many ways. Be it literacy policy, form of government, or cultural practices, this state does not always conform to the ideal that India is known for. Even so with their social structure. Certain tribes have remained matrilineal, where the decision-making power rests with the eldest female of the family.

A male member, who is the close confidante of the matriarch is chosen. He plays a crucial role in representing the male members of his family, and his opinion is highly valued. He is called karavanan. The men reside in separate rooms or in separate houses, and do not interfere in the upbringing of children. Property is also passed down along the lineage of the eldest female. Among the Nairs, matriarchy is more prominently adhered to than the Ezhavas, who have some patrilocal connections.
In Karnataka, the Bunts and Billavas belong to the Tuluva ethnic group. They are also a predominantly matriarchal society, founded on the belief in a legend. Their matrilineal descent is known as Aliyasantana.
The story is told of a demon who threatened to destroy a kingdom if the king did not sacrifice his sons, but the king's sister comes forward to offer her children in sacrifice for the sake of the kingdom. The demon is touched and does not destroy the city. Since then, the kingdom, or the property is inherited through female lineage.

In the recent past, many of these matriarchal societies have been reduced to matrilineal societies by certain governmental laws. They fall under the patriarchal scheme of the rest of the state but have reserved the right to pass on property and heritage through the female line. In the North east of India, matriarchal dominance is far more resilient than the south.
