Gujarat bans plantation of exotic Conocarpus trees

Widely visible across the state – from the Sabarmati riverfront in Ahmedabad to the Ram Van “urban forest” in Rajkot, rows of Conocarpus trees, an exotic mangrove species, had been a popular choice for increasing the green cover in Gujarat in recent years.

But, the state government has now banned its “plantation in forest or non-forest area”, underlining its “adverse impacts on environment and human health”.

Earlier, Telangana too had banned the same plant species.

> Trees of this species flower in winter and spread pollen in nearby areas. This is causing diseases like cold, cough, asthma, allergy.

> Their roots go deep inside the soil and develop extensively, damaging telecommunication lines, drainage lines and freshwater systems

> In 2018 Delhi decided to clear the Vilayati Kikar – a tree not native to Delhi (was brought to the city in the 1930s by the British). As it grew fast even in arid conditions, it kills off native trees like acacia, dhak, kadamb, amaltas, flame-of-the-forest, etc. which in turn is depleting the fauna — birds, butterflies, leopards, porcupines and jackals. In 2016, the Madras High Court too passed an interim order for the removal of these trees as they were depleting the water table.

> In Kerala’s Munnar, another British introduced tree, Eucalyptus, was stopped from being cultivated in forest tracts in 2018 after a study found that foreign invasive plants had reduced the availability of fodder in forests, forcing animals to foray into settlements and farmlands.

Einstein’s 108-year-old prediction on antimatter finally observed by scientists

Europe’s physics lab CERN announced that for the first time, scientists have observed antimatter particles falling downwards due to the effect of gravity.

The experiment was hailed as “huge milestone”, though most physicists anticipated the result, and it had been predicted by Einstein’s 1915 theory of relativity.

> Around 13.8 billion years ago, the Big Bang is believed to have produced an equal amount of matter (what everything you can see is made out of) and antimatter (the equal yet opposite counterpart of matter).

> However, there is virtually no antimatter in the universe, which prompted one of the greatest mysteries of physics: what happened to all the antimatter?

> Physicists believe that matter and antimatter did meet and almost entirely destroyed each other after the Big Bang. Yet matter now makes up nearly five percent of the universe — the rest is even less understood dark matter and dark energy — while antimatter vanished.

India’s first green hydrogen fuel cell bus flagged off in New Delhi

The initiative is part of a pilot project by Indian Oil which will see the fleet cover more than three million kilometres. It will hold operation trials in Delhi, Haryana, and Uttar Pradesh.

The two buses have been purchased from Tata Motors. The buses will initially run in Delhi-NCR sans passengers.

15 more such buses are expected to ply on the roads of Delhi-NCR by the end of this year.

KnowALLedge Plus

> The buses each have four cylinders that can hold 30 kilos of hydrogen. The tanks can be refuelled in 10-12 minutes.

> These buses will also be more fuel efficient – covering 12 kilometres per kilo of hydrogen as against 2.5 to 3 kilometres per litre for diesel buses.

> Hydrogen will be India’s transition fuel for moving away from fossil fuels.
It is Environment-friendly: Only water vapour is emitted as a by-product when hydrogen is burnt, which means, no emission of polluting gases.
It is Energy efficient: Green hydrogen fuel has three times the energy density thereby making it not only a cleaner alternative but also more energy efficient.

Father of Green Revolution in India passes away at 98

Monkombu Sambasivan Swaminathan, the man who made India a food-surplus nation is no more. The renowned geneticist and administrator who transformed the nation’s food production and security, passed away on September 28, 2023 in Chennai.

In the 1960s, he was working as a plant geneticist at the Indian Agricultural Research Institute, when he learned about the high-yielding varieties of wheat being tested in Mexico by the American food scientist Norman E. Borlaug. When the latter arrived in India in 1963, Dr. Swaminathan accompanied him on a tour of Punjab and Haryana.

The results were astounding. India’s wheat production grew five times between 1960 and 1970. Rice production too doubled in the same period. India not only became self-sufficient in food grains, but also started exporting to other countries.

>The Bengal famine of 1943 pushed M.S. Swaminathan to study agriculture, instead of medicine. He joined the Agriculture College at Coimbatore, did his postgraduate studies in plant genetics in the Netherlands and earned his Ph.D. in genetics from the University of Cambridge in 1952. His subsequent specialization in potato breeding prompted the University of Wisconsin in the USA to invite him to spend time as a postdoctoral fellow.

>Some of the posts he was ushered in his storied career include: Independent Chairman of the Food and Agricultural Organisation Council (1981-85), President of the International Union for the Conservation of Nature and Natural Resources (1984-90), President of the World Wide Fund for Nature (India) from 1989-96 and the Director General of Indian Council of Agricultural Research (ICAR), among others.

>In 1987, when the World Food Prize ( often referred to as the “Nobel Prize for Food and Agriculture”) was started by Dr. Norman E. Borlaug, Swaminathan became its inaugural recipient. He used the prize money (a hefty sum of $200,000) to start the M.S. Swaminathan Research Foundation, in Chennai.  He was also awarded with Ramon Magsaysay Award in 1971 and the Albert Einstein World Science Award in 1986.

>  MS Swaminathan was named one of the 20 most influential Asians of the 20th century by Time magazine. The only other Indians on this list include Rabindranath Tagore and Mahatma Gandhi, who greatly inspired him in the first place.

World’s largest and smelliest flower may be extinct soon

According to new research, most species of the famously large Rafflesia flower, which has long captured the imagination with its enormous speckled red petals, are now at risk of extinction.

Thriving in rainforests, it is in danger of extinction due to habitat loss as well as poaching — its buds are harvested and sold for medicinal properties.

KnowALLedge Plus

> This largest known individual flower of the Earth is found only in Malaysia, Sumatra, Java & Kalimantan of Indonesia, southern Thailand, and southern Philippines.

> It has a smell like rotten meat making it known locally as “corpse flower”

> Rafflesia is actually a parasite, and lives on tropical vines across parts of Southeast Asia, producing blooms that are among the largest in the world.

> The plant cannot grow in captivity, and, as most occurrences of Rafflesia contain only male or female flowers, pollinations is rare. A fly must land first on a male flower, avoid being eaten, and then transport the pollen to a female flower.

> The flower was first discovered by French naturalist and adventure, Louis Dechamps in then Java (present day Indonesia) between 1791-1794. It was named after Sir Thomas Stamford Raffles, an adventurer and founder of British colony of Singapore.
