IISc. researchers have nano solution for wastewater treatment

They 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.

PM Modi mentions Karnataka palm leather startup in ‘Mann Ki Baat’

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).

All should join hands with govt for conservation: Forester in Karnataka

As there is a lot of pressure on forests due to linear projects, the forest department alone cannot safeguard them and everybody should join hands for conservation and protection, Additional Principal Chief Conservator of Forests Kumar Pushkar said.

During the distribution of the Cricketers for Wildlife Conservation’s Wildlife Service Award 2022, organised by Karnataka Forest Department, he said NGOs, conservationists and celebrities should engage with the government in conservation and protection.

Forest watcher from BRT Tiger Reserve, Fairoz, along with wildlife conservationists — Sunitha Dhairyam (Mariamma Trust, Bandipur Tiger Reserve), Akhilesh Chipli (Shivammoga) and Colonel C M Muthanna (Kodagu) — were felicitated by former Indian cricketer and National Cricket Academy director VVS Laxman in the city on Saturday.

The awardees are chosen by a team of panellists from the forest department, including conservationists, based on their work. Laxman expressed concern about climate change and asserted the need to protect forests to mitigate the effects.

There are challenges, which need to be overcome for better results, he added using the platform to encourage youth in sports, but also stressed on the need for quality education.

Bengaluru couple’s dream of creating food forest blooming as ‘Vrukshavanam’

The vision to behold nature in all pristineness, an inclination to find an organic way of life and diet, and a call to connect with trees! This beautiful potpourri of thoughts conceptualised into ‘Vrukshavanam’, a lush food forest lovingly nurtured by a Bengaluru couple.

Pushpa Kallianpur, who envisioned Vrukshavanam, was always passionate about all things natural. The 46-year-old dentist-turned-makeup artist was just 12 years old when the thought to produce and consume her own food dawned on her. In 2010, in what was nothing short of prophetic, she sketched a picture of a country house surrounded by greenery, little knowing that a decade later, this dream drawing would manifest into reality through able support from her husband, photographer Kishan Kallianpur.

“Vrukshavanam was our dream, which we embarked upon two-and-half years ago. The idea was to create an ecosystem of trees and plants, providing us with vegetables, fruits and flowers, eventually metamorphosing into a food forest,” Pushpa says.      

A food forest resembles a forest garden, where every plant or tree is food-giving, self-renewing, sustainable, requires low maintenance and implements a stable design system, mimicking and behaving like a forest. Once the required flora has been introduced, the land overtime adapts to natural changes on its own, with almost zero human intervention, even as it provides food. This whole idea stands on the concept of ‘permaculture’, which refers to the growth of agricultural ecosystems in a self-sufficient and sustainable way.    

Occupying a quarter-acre plot within a gated community at Kodikonda in Sri Sathya Sai district of Andhra Pradesh, Vrukshavanam today is home to at least 150 trees, including those that are fruit-bearing, medicinal and floral, apart from vegetable-yielding plants.    

Reminiscing her green journey, Pushpa mentions, “About six years ago, we set up a small kitchen garden on the terrace of our home in Rajajinagar, which met most of our food needs. Then I thought that we could replicate a similar design on a natural, larger scale. After careful research, I found what I was looking for was in permaculture, and I wanted to create a green patch which was pesticide-free, drawing all its nutrition from the earth. I also undertook a course in permaculture design, in furtherance of my vision.”

She adds, “We purchased the plot before the onset of Covid. The land was barren, but we didn’t introduce any soil from outside, applying inputs in the form of organic manure and homemade compost. Since it is topographically a grassland area, not much human interference had taken place. We gradually tended the soil over a three-month period, planting trees from the scratch. A few plants were transplanted from our terrace garden too. Today, other than rain, our land receives water through drip-irrigation.”

Vrukshavanam also symbolises a relevant shift towards leading a holistic life, promoting the right kind of food, besides how it is consumed. Adhering to permaculture guidelines, the forest works in sync with nature, producing pesticide-free, organic and nutrient-dense food.

“Nutrient-dense food coming from live soil is the need of the hour, and we intend to project Vrukshavanam as a model food forest by not only growing food over a small area, but also addressing basic needs like water, shelter, right cooking methods, energy and nutrition, well-aligned with nature,” she says, adding that with many birds visiting, there is frequent dispersal and germination of tree-bearing seeds.

This simple, yet painstaking approach, has got several people interested, and the couple had also organised a workshop in the past, involving a naturalist. “Our intention is to bring awareness through workshops related to these topics and also let people experience Vrukshavanam through visits and stays in the near future,” says 47-year-old Kishan.

Completing the overall natural appeal of the place, the couple has built a cottage — Shambhala Mane — for themselves within Vrukshavanam. “Shambhala Mane is alive with breathable mud walls, ample sunlight and fresh air, setting an example of how we need to be connected with nature,” concludes Kishan, highlighting that their dedicated natural selection is bearing fruit.

WHAT IS PERMACULTURE?
Permaculture was conceived by ecology experts Bill Mollinson and David Holmgren in Australia, in the 1970s. According to the Permaculture Research Institute, permaculture is the conscious design and maintenance of agriculturally productive ecosystems which have the diversity, stability and resilience of natural ecosystems. It is the harmonious integration of landscape and people — providing their food, energy, shelter, and other material and non-material needs in a sustainable way.

Veggie-fruit basket
A host of vegetables, flower- and fruit-bearing trees and plants call Vrukshavanam home. Some of these include avocado, custard apple, guava, starfruit, papaya, banana, orange, mango, apple, coconut, gooseberry, carrot, cabbage, hibiscus, champa, nagachampa, jasmine, and a lot of greens. A few medicinal plants include amaranth, simarouba, soursop, and soapnut. Most of the vegetation here automatically adapts to the changing seasons.

Environmentalist Kame Gowda praised as ‘Water Warrior’ by PM Modi no more

Kame Gowda, an environmentalist, whose efforts to build 16 lakes were praised by Prime Minister Narendra Modi, passed away on Monday in Mandya district of Karnataka.

Also known as Kalmane Kame Gowda, 86-year-old Kame Gowda breathed his last at his residence in Dasanadioddi village.

PM Modi had called Kame Gowda a ‘Water Warrior’ and praised for his efforts to build 16 lakes in the region in his monthly radio programme ‘Man Ki Baat’ on June 28, 2020.

Gowda, a shepard, born to Venkata Gowda and Rajamma couple, did not go to school. However, his love and association towards his flock of sheep brought him closer to nature.

After PM Modi mentioned his name and lauded his achievement, he came into limelight. The Associated Press published a detailed article on him through which his efforts were recognised at the international level.

PM Modi had stated that Kame Gowda, who had built lakes on his own money for the sake of birds and animals is a model. Kame Gowda, came to know about the importance of water. He had taken up “Jal Kayak” (water preservation) with hard work. Due to his efforts the green cover in the region has improved, PM Modi then stated.

Kame Gowda had spent his life time savings to build water bodies. He had expressed that he wanted a house, job for his children and land for the development of lakes.

During the tenure of former CM B.S. Yediyurappa, the government had provided financial assistance. Presently, Health Minister Dr K. Sudhakar had taken care when Kame Gowda fell ill.

Talking about what made him build water bodies, Kame Gowda had said that he could not get drinking water in the Kundur hill region due to which he faced a lot of difficulty. He had to walk a long distance, asking for water from strangers’ houses. That made him think, what would the birds and animals be doing in the absence of water.

That inspired him to build lakes. People laughed at him and called him mad when they saw him digging dry lands. However, unaffected by all criticism, he continued his work.

Chief Minister Basavaraj Bommai paid his condolences to Kame Gowda and lauded his efforts.

On the ground learning

Asia’s first RDPR University offers courses to empower students who can further empower rural India.

Mahatma Gandhi’s profound remark, “The soul of India lives in its villages”, resonates through every pulse of the nation even today. About 65 per cent of the Indian population continues to reside in rural areas, adhering to a lifestyle grounded in tradition. However, as India progresses into an era of modernisation on par with its developed global peers, the country’s villages are trying to catch up with the modern times, while preserving their ethos.

Spearheading this process academically is a unique university in Karnataka, which imparts learnings in Gandhian thought, herbal medicine, rural lifestyle, addressing rural socio-economic problems, and traditional vocations, among others. The Karnataka State Rural Development and Panchayat Raj University (KSRDPU) is situated in Nagavi village of Gadag district.

Plan in action
Rural Development and Panchayat Raj are the two main pillars acting as catalysts to change the country’s rural scene for the best. Hence, a university aimed at heralding positive change in the rural areas of North Karnataka was envisioned.

The proposal to establish such a university was approved by both Houses of the Legislature in the Chief Minister’s Budget speech of 2013-14, following which a state government-constituted expert committee visited several academic institutions, such as Institute of Rural Management Anand; National Institute of Rural Development, Hyderabad; Gandhi Gram, Madurai; Indian Institute of Management, Ahmadabad; and Tata Institute of Social Sciences, Mumbai, to come up with an idea for the RDPR University. The committee’s vision through the proposed varsity was to create a committed, dedicated professional workforce to address various issues affecting rural development.

Accordingly, the university had its inception at Raita Bhavan near Bhishmakere in 2016, with academic activities beginning the following year. Later, a plan to establish a full-fledged RDPR University was mooted by the then RDPR Minister H K Patil, following which a new campus was inaugurated in 2018 by the then Chief Minister Siddaramaiah. This campus came up on 353 acres of land near Nagavi. The pleasant weather emanating from the Kappatagudda hillock nearby made this village ideal for learning, especially for the study of subjects surrounding rural and village topics.

Today, this varsity focuses on research, teaching and training in the realms of sustainable rural development through the institution of Panchayat Raj. Special courses include MA in Geoinformatics (Remote Sensing and GIS), MA in Public Administration, MA in Rural Development and Panchayat Raj/Cooperative Management, MBA in Rural Management and Agribusiness Management, MSW in Community Development, Rural Reconstruction and Community Health, M. Com in Entrepreneurship or Cooperative Management, Master of Public Health, and much more.

According to Prakash Merawade, a lecturer at KSRDPRU, “At the university, we teach traditional Ayurvedic herbal medicine and use of charkha for making cloth as well. Students are exposed to practical experiences of rural problems, by getting them to visit the villages of Gadag district.”

“There was a need for such an institution, which is guided by Gandhiji’s idea of Gram Swaraj. We have also built a replica of Sabarmati Ashram on campus so that students can study and imbibe Gandhian philosophy. Today, KSRDPRU works on four main aspects — education-based, research-based, training-based and area-based learning,” concludes KSRDPRU Vice-Chancellor Vishnukant Chatpalli.

The KSRDPR University claims to be the first-of-its-kind institution in Asia, whose sole purpose is to create thought leaders and professionals who will work among rural-folk, bridging the development divide with their urban brethren, thereby blending traditional with modern in a diverse India.    

LIFE AND TIMES 

The KSRDPRU campus hosts a replica of the Gandhi Smarak of Sabarmati Ashram in Gujarat, which has been created by the KSRDPRU itself, and is located 10 km away from Gadag town. The ashram is located in the lap of Kappatagudda. The structure has five rooms, comprising a meditation centre, library, Nayee Talim centre, Gandhi Kasturba Kutir, and a kitchen. There is also a big statue of Mahatma Gandhi in the veranda, which can accommodate 60 people for attending speeches on Gandhian principles. The rooms also have a collection of photographs from the life and times of the Mahatma, besides a replica charkha like the one in Gujarat’s ashram.

TRADITIONAL HUT FOR HERBAL MEDICINES

The university has also built a Parnakuti, a traditional hut to create awareness on Ayurveda. Students, traditional doctors and Ayurveda experts are brought here to share their knowledge on medicinal plants. Varsity staff grow Ayurvedic plants at Smritivana on campus. Parnakuti, which has been built using natural materials such as bamboo, eucalyptus wood and dry grass, encourages students to touch base with traditional healers, following practices like in the ancient times, when there used to be an Aushadha Vana, Rajvana and Panchavati Vana, where medicinal plants were cultivated.

MANOCHETANA COUNSELLING CENTRE

The university has started Manochetana, a free counselling centre for people who are under stress after the pandemic. Free counselling can be sought at the old building, in the old DC’s office building in Gadag town. This facility is open to farmers, health workers, students, and people from both rural and urban areas.

Bengaluru’s Indian Institute of Horticultural Research tops the list of 93 ICAR institutes in national ranking

Plant varieties and technologies developed by Institute located in Hessarghatta is contributing about ₹13,000 crore a year to country’s exchequer

Bengaluru has got one more feather in its cap with the Hesaraghatta-based Indian Institute of Horticultural Research (IIHR) being ranked top among institutions run by the Indian Council of Agricultural Research (ICAR).

The IIHR has topped the combined list of ranking for 2019-20 and 2020-21 that was released by the IIHR on Wednesday.

In all, 93 various institutes run by the ICAR in different parts of the country were considered for ranking.

The ranking is done on various parameters including the institute profile, performance, recognition and awards received by its faculty, research output and outcome, impact of research taken up by the institute, and vision and future readiness of the institute.

While each of these parameters were allotted certain marks, the institutes were judged for a maximum of 100 marks.

Vast research

IIHR conducts research on 54 major horticultural crops and has released 330 hybrids and other varieties in these crops ever since its inception in 1967.

The institute has also released 157 technologies that have played a major role in boosting horticultural productivity in the country. The estimated impact of eight of these selected hybrids/varieties and technologies to the national exchequer is around ₹13,000 crore annually.

The institute is also focusing on the promotion of entrepreneurship through horticultural technologies and at present there are three technology business incubators in operation at the institute to hand hold and promote horticultural entrepreneurship.

Seed portal

In a first-of-its-kind initiative in the country, the IIHR recently launched an online portal for the sales of the seeds of the varieties released by it.

Institute Director Debi Sharma said the recognition for ICHR had increased the responsibility of the institute. IIHR was keen on pursuing its cutting edge research in new areas, she said.

Meanwhile, the National Bureau of Agricultural Insect Resources and the National lnstitute of Veterinary Epidemiology and Disease lnformatics, which too are ICAR institutes located in Bengaluru, have got the 23rd and the 50th rank respectively.

Mysuru zoo rated second best in CZA evaluation

The century-old Mysuru zoo has been rated ‘very good’ by the Central Zoo Authority (CZA), which conducted the Management Effectiveness Evaluation of Zoos in India 2022. The country’s medium and large zoos were comprehensively evaluated during the first-ever exercise by the CZA.

Though Mysuru zoo has been adjudged ‘very good’ among large zoos during the assessment by the experts, it, however, stands second as Arignar Anna Zoological Park in Chennai has secured a score of 83 marks and was graded ‘very good’ by the CZA. The Mysuru zoo has got 80 marks but yet graded ‘very good’ in the evaluation considering its best management practices and standards.

Expressing happiness over the rating, Executive Director Ajit Kulkarni said the evaluation was done for the first time by the CZA and an expert team had visited the zoo to appraise the zoo and its practices. “Whatever suggestions have been made for the zoo’s improvement will be implemented. The action to be taken, as endorsed by the CZA, will be looked into,” he said.

Among the medium zoos, the Padmaja Naidu Himalayan Zoological Park, Darjeeling, is rated the best, according to the evaluation report.

The CZA, in its report, said the mission, vision, objectives and strategies mostly identified at the Mysuru zoo but need to be systematically formulated and documented as per the National Zoo Policy. The zoo has been told to make efforts to pair all single animals.

Also, the conservation breeding programMEs for Gaur, Nilgiri Langur, Lion-tailed Macaque, Dhole, Indian Grey Wolf etc., can be managed with improved scientific rigour and with the development of detailed plans for conservation breeding including genetic profiling, individual marking of names for identification, community engagement plan, plan for soft release, and survey of release sites, the CZA said, in its evaluation of the Mysuru zoo.  

The Mysuru zoo management must pursue the development of an interpretation centre, according to the report.

Citing about the best practices at the Mysuru zoo in its evaluation, the CZA said the zoo is one of the self-sustainable zoos. In the past two decades, the zoo administration has introduced many interventions, innovations and programs — from waste management policy, to a flexible animal adoption programme. After segregation of the waste, the biodegradable waste is used for making biogas, vermicompost, and manure in the campus itself. Biogas is used in zoo kitchens. The zoo has tie-ups with various NGOs for the recycling of plastic waste. The zoo harvests 79 crore litres of rainwater through directed infrastructure changes. The surrounding areas of the zoo and the farmers have also been benefited by the system as no borewells go out of water during summer. The zoo also provides RO drinking water for free to the visitors. Seventy percent of water that gets wasted from the RO units are reused On the zoo premises.

The CZA said the MEE assessment is an inclusive exercise – the assessment is based on information and documentation produced by the zoo and the detailed site visit.

The actionable points derived from the assessment, along with pillars of change indicated in the vision plan for Indian zoos (2021-2031), can become the catalyst for the transformation, build innovation and leadership and help zoos deliver experiences that inspire visitors to take conservation action and affirm deeper community connect, the CZA concluded in its assessment, a report of which has been sourced by The Hindu.
