This city-based documentary maker’s latest explores the life of celebrated horticulturist HC Javaraya.
It is known to every Bengalurean that German horticulturist Gustav Hermann Krumbiegel, changed the landscape of the city, but his successor HC Javaraya also had an equal contribution to it. The latest book by Meera Iyer, a writer, researcher and convenor of INTACH, Bahadur HC Javaraya: A Gardener and a Gentleman, revolves around the life of horticulturist HC Javaraya. Inspired from the book, city-based filmmaker Ganesh Shankar Raj has adapted it into a documentary.
Raj says Javaraya was one of the key and native horticulturists in India, and the first deputy superintendent of Lalbagh. “He was a successor of renowned horticulturist Gustav Hermann Krumbiegel, who actually set up various gardens in Bengaluru. Even the Indian Institute of Horticulture and Research (IIHR) was set up by this gentleman as a Fruit Research Institute in the 1930s. Today, it has grown to become one of the premier institutes in the country. He is the one who created the famous ‘Agmark’ for fruits,” says Raj.
Javaraya was known as the fruit man of the then Mysore state. “If you see so much fruit cultivation in Bengaluru, it is because of him. He introduced a wide variety of fruits in Bengaluru. He was even the first person to cultivate apples. There was a thriving apple cultivation that took place in Bengaluru during his time and then everything died down,” says Raj, adding that Javaraya is an unsung hero. “Nobody knows about him. So, therefore, we decided to make a film in association with the family,” Raj further adds.
Raj’s last documentary was on Krumbiegel and he admits to having a soft spot for horticulturists who shaped Bengaluru. “We do different kinds of films, but these people have done a tremendous amount of work for the city. In Bengaluru, you can see a lot of trees, gardens and flowers…these stalwarts were responsible for it. Therefore, we decided to make a film that speaks about their contribution,” says Raj.
The product developed at Nitte’s DST TEC is available online.
Mysuru-based start-up, Eshanya Beverages, on Friday formally released ‘Betel leaf tea bags’, which was developed at NITTE (Deemed to be University) DST Technology Enabling Centre (DST TEC).
Sandeep Eshanya, a resident of Vijayanagar in Mysuru, told reporters that he quit his job in Bengaluru during COVID-19 second wave. He read a research paper on betel leaf tea. “I was fascinated with the idea as I come from the land of betel leaf and approached a few start-up incubation firms.” NITTE DST TEC agreed to support Mr. Eshanya and NITTE University’s Centre for Science Education and Research (CSER) was asked to study the product.
B.S. Mamatha from NITTE’s CSER said they researched on the product for a year. The research involved the way the betel leaves can be dried and cut into small pieces, which will release its natural taste when placed in hot water. “It took a year to come out with the product that had mild and natural taste of betel leaf,” Ms. Mamatha said, adding the product retains the health benefits of betel leaf.
Mr. Eshanya said apart from natural flavour, they brought out betel leaf bags in orange, rose petals, and lemon flavours. His wife Rani Vishwanath said they approached Ramaiah Evolute, start-up incubator of M.S. Ramaiah Institute, where they received help from Sadananda Maiya, a pioneer of ready-to-eat products, in marketing the product.
Eshanya Beverages sold over 300 boxes of tea, each containing 50 bags and priced at ₹349, through an online platform recently. Betel leaf tea bags are available in retail stores in Mysuru, Mr. Eshanya said.
Launching the product, NITTE Vice-Chancellor Sateesh Kumar Bhandary said TEC set up at NITTE is among a few set of TECs set up by the Union government’s Department of Science and Technology across the country. “Since the last three years, TEC has been supporting new entrepreneurs,” he said.
Iddya Karunasagar, advisor (Research and Patent), NITTE, said the TEC recently transferred technology of making of almond milk powder to a Delhi-based start-up. Technology transfer related to two more products of TEC is in the pipeline, he said.
Modi interacts with camp staffers for 15 mins, who explained the nature of their duty and challenges.
PM Narendra Modi, who launched a three-day mega event to mark 50 years of Project Tiger, is likely to declare Karnataka the ‘Tiger State of India’. As per a recent assessment by the National Tiger Conservation Authority (NTCA) and Wildlife Institute of India, it is expected that Karnataka has overtaken Madhya Pradesh in tiger population.
As per the 2018 tiger estimation, Karnataka came second with 524 tigers, while Madhya Pradesh with 526 tigers took first place. The country has 2,967 tigers, and efforts of forest officials in protecting wildlife and forests are expected to have increased the tiger population in the state and country.
The rapid increase in human population over the centuries led to a decline in wildlife in the country. There was large-scale hunting of wildlife, especially tigers, for pleasure during the period of the Mughals, Maharajas and Nawabs, as well as to save people from attacks of wild animals. During British rule between 1895 and 1925, it is reported that over 80,000 tigers, more than 1.50 lakh leopards and 2 lakh wolves were hunted in the country.
According to the Kanara District Gazetteer 1883, the British government gave incentives for killing tigers — Rs 24 for hunting an adult tiger, Rs 12 for a sub-adult tiger and Rs 6 for a tiger cub. As a result, in the 27 years between 1856 and 1882, 640 tigers were shot dead in Kanara, 158 tigers from 1856 to 1866, 350 tigers between 1867 and 1877, and 130 tigers between 1878 and 1882.
As per the 1954-55 Administrative Report of the forest department of the Government of Mysore, Kakanakote State Forest, Begur State Forest, Berambadi State Forest, Bandipur State Forest and Chamarajanagar State Forest in Mysore District, Lakkavalli State Forest in Chikkamagaluru District, Shankar State Forest in Shivamogga district and Hessaraghatta Grass Farm in Bengaluru district were declared game preserves, and Puduvakote Forest Block, Manche Gowdanahalli forest block and Bale Gowdananakatte forest block in Mysuru District, Gurupura forest block in Chikkamagaluru, Kadathikere and Devabu blocks in Shivamogga district were declared tiger preserves.
The first comprehensive legislation regarding wildlife protection was passed by Parliament and the President on September 9, 1972, called Wildlife Protection Act 1972. Then PM Indira Gandhi launched Project Tiger, providing assistance to states for tiger conservation.
However, before the WPL 1992, a number of wildlife sanctuaries — Venugopala Wildlife Park (1931), Ranganathittu Bird Sanctuary (1940), Bandipur Wildlife Sanctuary (1941) and Jagger Valley Wildlife Park (1951) in Mysore state, Nagarahole Wildlife Sanctuary (1955) in Coorg state and Dandeli Wildlife Sanctuary (1956) in Bombay Presidency — established by princely states were merged into Karnataka in 1956.
As per the Karnataka State Gazetteer, 1982, when Project Tiger was launched, Bandipur National Park was brought under it in 1973. Nagarahole National Park and Bhadra Wildlife Sanctuary were made tiger reserves in 1999. However, Dandeli Wildlife Sanctuary and Anshi National Park were brought under Project Tiger in 2007 under the name Dandeli-Anshi Tiger Reserve.
It was later renamed Kali Tiger Reserve. Biligiri Rangaswamy Temple (BRT) Wildlife Sanctuary was declared a tiger reserve in 2011. The forest department has sent a proposal to the central government to include Kudremukh National Park, Cauvery Wildlife Sanctuary and Male Mahadeshwara Hills Wildlife Sanctuary and Bhimgad Wildlife Sanctuary in Belagavi district in Project Tiger. Bhimgad Sanctuary is a critically important tiger corridor between Karnataka and Goa.
ACCURATE NUMBERS Former Mysuru honorary wildlife warden and Wildlife Conservation Foundation founder Rajkumar Devaraje Urs told TNIE that as tiger estimation was done based on pug marks in the past, there was no accuracy in counting tigers. “After camera traps were introduced, foresters achieved accuracy. The major threat to tigers is forest fires and poaching. If reserve foresters and island pockets are included in the tiger reserve, India has a chance to have a tiger population of 10,000 in future. If there is a good tiger population, forests will be healthy which increases rain, resulting in an increase in groundwater table and rivers.
90% of rivers originate in tiger reserves
As I conclude a memorable visit to the Bandipur and Mudumalai Tiger Reserves, I want to acknowledge the hard work of all forest officials, guards, tiger reserve frontline staff and everyone else working on tiger conservation. Words can’t do justice to their passion and effort. What a delight to meet the wonderful Bomman and Belli, along with Bommi and Raghu. — Prime Minister Narendra Modi
‘No conflict of economy, ecology’ Mysuru: Wildlife protection is a universal issue, said Prime Minister Narendra Modi on Sunday at the Karnataka State Open University convocation hall in Mysuru. Stating that India contributes to around eight per cent of the known global biodiversity, he said that India has not only saved the tiger population from declining but also provided an ecosystem where they can flourish, and was delighted that the tiger population has increased by 75 per cent. “India does not believe in a conflict between ecology and economy, and gives importance to their coexistence,” Modi said, adding, “India is a country where protecting nature is a part of our culture”. “India has the largest tiger range in the world, the largest Asiatic elephant range with around 30,000 elephants, and also the largest number of single-horn rhinos with a population of roughly 3,000,” he said. India’s Asiatic lion numbers have increased from around 525 in 2015 to around 675 in 2020, he said, adding that the leopard population has jumped by more than 60 per cent over 4 years.
Appe midi is a traditional pickling variety of mango from Karnataka, which is grown in the Malnad region of the State-especially in Sirsi, Sagara, Siddapur, Thirthahally, Kumata, Sakleshpur, Kodagu and Chikkamagaluru.
Thanks to the growing popularity of ‘appe midi ’ (tender mango in Kannada), the Indian Institute of Horticultural Research (ICAR-IIHR) in Hesaraghatta for the first time will conduct an exclusive ‘appe midi’ mango fair, where 100 varieties of such mangoes will be displayed.
Appe midi is a traditional pickling variety of mango from Karnataka, which is grown in the Malnad region of the State-especially in Sirsi, Sagara, Siddapur, Thirthahally, Kumata, Sakleshpur, Kodagu and Chikkamagaluru.
The fair will be held on April 12 and 13 on the IIHR campus in Hessarghatta.
Creating awareness
Speaking to The Hindu, M. Sankaran, Principal scientist, division of fruit crops, ICAR-IIHR, said, “Appe midi mangoes have a unique position with respect to the diversity of pickling mango varieties. Appe midi is the king of all tender mangoes as far as its use in the pickle industry is concerned. Since there is a demand and awareness has to be created on this variety of mangoes, we thought of conducting an exclusive fair.”
The IIHR will display 100 varieties of tender mangoes at the fair, which are preserved by IIHR and also grown by farmers in various parts of the State. “The custodian farmers from across the State will participate at the fair where 100 appe midi mango genotypes will be displayed. The pickle manufacturers will also sell their products made of tender mango. Apart from this, we will also distribute limited appe midi mango saplings to farmers,” Mr. Sankaran added.
According to IIHR, the pickles prepared from appe midi mangoes make for an exquisite culinary experience. The demand for pickles varies from 4,000 to 5,000 tonnes per year, translating to ₹100 crore per year.
Unorganised market
“A good quality tender mango costs ₹2 to 3; the price for a quintal could go up to almost ₹6,000, depending on demand and availability. Since the supply of appe midi meets only one-tenth of demand in the market, they are often mixed in with ordinary tender mangoes. This is not an organised market compared to others. Appe midi products have a high potential for marketing and need attention for conservation. The mango’s unique size and taste make its pickle one of the best in the country, with its fragrance so strong that adding just a few midis to an ordinary pickle can change its taste and smell,” Mr. Sankaran explained.
A wild appe midi tree can yield several tonnes of tender mango, with features varying from tree to tree. In Karnataka, 100 farm households are engaged in making appe midi pickles producing at least 100 tones of pickle a year. ICAR-IIHR has so far surveyed, collected and conserved more than 250 accessions of appe midi mangoes. These mangoes have a huge market in Goa, Tamil Nadu and Kerala, according to IIHR.
The supercapacitor is fully functional and can be deployed in energy-storage devices like electric car batteries or any miniaturised system by on-chip integration.
Researchers at the Indian Institute of Science (IISc) have developed a new type of supercapacitor that can replace batteries in streetlights, electric cars and medical devices.
The supercapacitor, developed by researchers from IISc’s Department of Instrumentation and Applied Physics (IAP), is different from others, as it is smaller or ‘ultra-micro’, but capable of storing larger amounts of energy. Hence, the supercapacitor can be easier to use in smaller electronic devices, eliminating the need for batteries, while ensuring that the device stays charged for a longer time.
“Most of these devices are currently powered by batteries. However, over time, these batteries lose their ability to store charge and therefore have a limited shelf-life. Capacitors, on the other hand, can store an electrical charge for much longer, by their design. Supercapacitors, on the other hand, combine the best of both batteries and capacitors — they can store and release large amounts of energy, and are therefore highly sought-after for next-generation electronic devices,” the researchers said.
Abha Misra, an IAP professor and a corresponding study author, said the supercapacitor used Field Effect Transistors (FETs) instead of metallic electrodes, which are more commonly used, as charge collectors. “Using FET as an electrode for supercapacitors is something new for tuning charge in a capacitor,” she said.
During their tests, they found that the ultra-micro supercapacitor, due to the materials used, was able to increase capacitance (ability to store energy as electricity within the device) to 3,000 per cent. This was compared to a regular supercapacitor, which showed only an 18 per cent increase. The key was the use of molybdenum disulphide (MoS2) and graphene in increasing the mobility of electrons within the supercapacitor.
“In future, we are planning to explore if replacing MoS2 with other materials can increase the capacitance of the supercapacitor even more. The supercapacitor is fully functional and can be deployed in energy-storage devices like electric car batteries or any miniaturised system by on-chip integration. We are also planning to apply for a patent on the supercapacitor,” they said.
The National Horticulture Fair 2023 (NHF2023), which will be held between February 22 and 25 in Hesaraghatta on the outskirts of the city under the theme of ‘Innovative horticulture for self-reliance’, will be inaugurated by Union Agriculture Minister Narendra Singh Tomar virtually on Wednesday at 12 p.m., said Sanjay Kumar Singh, Director of ICAR-IIHR and chairman of the organising committee NHF 2023.
The fair, being organised by the Indian Council of Agricultural Research (ICAR) and the Indian Institute of Horticultural Research (IIHR), will showcase latest technologies such as vegetable, flower and medicinal crop varieties for import substitution, pollination in protected cultivation, leaf curl virus resistant chilli varieties, carotenoid content rich marigold varieties, flower waste utilisation, terrace gardening solutions for urban horticulture, production technologies for exotic fruits such as dragon fruit and avocado and cost-effective traps for management of invasive pests, etc. for the benefit of horticulturists and other stakeholders during the NHF2023 at ICAR-IIHR.
The NHF-2023 will have 250 hi-tech stalls on various products and 50 nursery stalls, according to ICAR-IIHR officials.
Apart from this, officials said that special workshops and conferences on horticulture development on various aspects, including value added millet products, composting of bio-waste, urban horticulture, mushroom production and value addition, safe use of pesticides, preparation of incense sticks from floral waste and tribal horticulture, will be organised during the four-day fair.
Last year, the event was cancelled due to the pandemic, and in 2021, the fair was in a hybrid mode because of the pandemic. The institute is expecting about 50,000 farmers from various States of the country.
Hopcoms fair at Lalbagh
The Horticultural Producers’ Cooperative Marketing and Processing Society (Hopcoms) will oragnise grapes and watermelon mela at Lalbagh from Wednesday. Three to four varieties of watermelon and 13 to 15 varieties of grapes will be sold at the fair, according to a Hopcoms release.
The source of Cauvery is also among the most ideal locations to gaze at the sky.
Talacauvery in Kodagu district, which is the source of Cauvery river, has emerged as South India’s Hanle, as astronomers have been hosting “star parties” there for some time now. Hanle, located in Ladakh, and known for its pristine skies and minimal light pollution, is also India’s first Dark Sky Reserve.
A Dark Sky Reserve is a designation given to a place that has policies in place to ensure that a tract of land or region has minimal artificial light interference.
In south India, most dark sky locations are in the Western Ghats or some hill ranges nearby, and according to astronomers, Talacauvery is the most ideal location to gaze at the sky and have a star party.
Voluntary work
The Bangalore Astronomical Society (BAS), a group of volunteers working for the promotion of astronomy as a hobby as well as a science, is now hosting star parties at Talacauvery. IT professionals Sudhash Natarajan, Vishwanath S.K. and Keerthi Kiran have been volunteering to conduct the star parties for BAS.
“We at BAS usually arrange star parties on New Moon weekends (Friday-Saturday-Sunday) format as it is the ideal time to observe the celestial objects which we are looking for. We inform people who are interested in joining us for the star party eight to days in advance. Members of the sky party after arriving at the dark sky location set up their equipment like telescopes, binacolours etc and the observation goes on until 4.45 am,” said Sudhash Natarajan.
Mr. Natarajan said that the group which attends the star parties are of all walks of life and that they are a mix of experienced astronomers as well as students and newbies to astronomy. He added that star parties have also been conducted in Koratagere, Hoshalli, Kavalur, and Yercaud in the past.
Less light pollution
“However, Talacauvery is possibly the best dark night location in south India due to less light pollution. In astronomy, there is something called the Bortle scale which measures the night sky’s brightness of a location on a nine level numerical scale. The lesser the numerical scale it qualifies for a better dark sky location. For example, Hanle skies would qualify as Bortle one skies, Talacauvery as Bortle two, and Bengaluru as Bortle nine,” he added.
The star parties are usually conducted in the winter months between December to March as the skies are clearer during these months which is very important for stargazing.
Mr. Natarajan said a star party was conducted between December 23 and 27, 2022, and the next one would be between January 20 and 24.
They have developed a metal organic framework (MoF) nanocomposite by intercalating the properties of graphene oxide and UiO-66-NDC.
Researchers in the Indian Institute of Science’s (IISc.) have developed a novel nanocomposite material for improved wastewater treatment.
A team of the Interdisciplinary Centre for Water Research (ICWaR) in the IISc., led by Praveen C. Ramamurthy, has developed a metal organic framework (MoF) nanocomposite by intercalating the properties of graphene oxide and UiO-66-NDC.
Heavy metals
According to IISc., industrial effluents containing heavy metals have polluted our water sources for decades. Lead, a heavy metal commonly found in discharge from paint and battery manufacturing plants, is a major water pollutant whose presence severely affects human and animal health.
In recent years, scientists have turned to nanotechnology to develop absorbent materials that can remove heavy metals for improved wastewater treatment.
However, existing adsorption materials and technologies are expensive, and their applications are limited by where they can be implemented and how efficiently they can adsorb lead. This demands the development of novel, low-cost and structurally stable composite materials for wastewater treatment. To this end, ICWaR researchers have developed a novel nanocomposite material.
The researchers have demonstrated that the new nanocomposite can adsorb lead (Pb) from simulated wastewater systems.
Four-fold capacity to absorb lead ions from wastewater
The team demonstrated that the newly developed MOF nanocomposite adsorbent has approximately four-fold enhanced capability in removing lead ions from wastewater compared to previously reported studies of graphene oxide. The material exhibits a stable crystalline structure. Modelling and simulation results also support enhanced efficiency in lead adsorption due to the adsorbent molecular architecture.
The new nanocomposite has improved adsorption and high regeneration and reusability capacities, making it an effective tool in the wastewater treatment of lead ions.
The PM said the couple is sending many unique products made from betelnut fiber to the international market.
A Shivamogga-based couple’s out-of-the-box idea on the use of betelnut fibre has earned the praise of Prime Minister Narendra Modi. Suresh and his wife Maithili, who are residents of Vinoba Nagar, are exporting their palm leather products internationally.
Modi praised the couple in his Mann Ki Baat episode on Sunday and said the countrymen should use such indigenous products and gift them to others as well. Suresh and Maithili, through their startup Bhoomi Agri Ventures, are making and exporting areca palm products. Their palm leather project was instigated as a cheap plant-based replacement for animal leather, plastic and rubber.
The PM said the couple is sending many unique products made from betelnut fibre to the international market. “These people are making decorative things ranging from trays, plates and handbags from betelnut fibre. Chappals made of this fibre are also being liked a lot today. Today, their products are being sold in London and other markets in Europe.
This is the very quality of our natural resources and traditional skills, which is being liked by everyone. With the traditional knowledge of India, the world is looking at ways of a sustainable future. We ourselves also need to be more and more aware of this. We should use such indigenous and local products and gift them to others as well. This will also strengthen our identity, the local economy, and, in large numbers, brighten the future of the people,” he said.
Expressing happiness over Modi mentioning them in this radio programme, Suresh told TNIE that their project was possible thanks to the Rashtriya Krishi Vikas Yojana- Remunerative Approaches for Agriculture and Allied sector Rejuvenation (RKVY-RAFTAAR).
The solar power system offers 498.43 KWP capacity which is nearly 40 per cent of the power requirement of the institute.
The International Institute of Information Technology-Bangalore installed a 500 kVA rooftop solar power system in its campus recently. It was inaugurated by S Gopalakrishnan, Chairman, IIIT-B governing body.
The solar power system offers 498.43 KWP capacity which is nearly 40 per cent of the power requirement of the institute.
IIIT-B has installed 393 solar panels on rooftops and has upgraded its infrastructure to tap green energy.
Jagadish P Patil, Chief Administration Officer, said, “Our power requirement has shot up to 22% as there is an increase in student strength and upgradation of infrastructure. With this solar power system, we can reduce 40 per cent on the overall power bill.”
