Bengalurean’s ‘humane’ device to save crops from wild animals

Each device features four LED lights. The lights are positioned in pairs, in such a way that from a distance they look like a pair of glowing eyes of a predator, founder S R Ayan said.

A Bengaluren has designed a lighting system to help farmers protect their crops and livestock from wildlife, during the night. The innovative product does not harm the wild animals. Katidhan, a five-member startup located on New BEL Road, recently won an investment of Rs 1.5 crore on business reality show, Shark Tank India.

On the show, its founder S R Ayan said farmers in India lose 30-50% of their crops to wildlife. The conventional methods to keep wild animals out include installing electrical fences, planting crude bombs or spraying chemicals. Citing the dangers of such interventions, he said an elephant in Chikkamagaluru died due to electrocution by an electric fence last November.

Ayan says his product, Parabraksh, mitigates the human-animal conflict in a “humane way”. Animals are afraid of other animals and the lighting system is built around this behavioural psychology. “Each device features four LED lights. The lights are positioned in pairs, in such a way that from a distance they look like a pair of glowing eyes of a predator. This scares away the animal.”

The product flashes light in random patterns. Being an autonomous device, it switches on in the dark and switches off as daylight breaks. It runs on solar power but also features a USB charging port for backup.

“Four such lights are needed to protect a farm land of 1 hectare, one in each corner. You can mount them on bamboo sticks or steel poles. The height of the stick or pole will depend on the size of the animal you are targeting,” Ayan adds.

He claims Parabraksh is “over 95%” effective in repelling wild boar, nilgai, elephant, tiger, leopard, and the Himalayan bear. He shares case studies: When these lights were uninstalled from a farm in Tamil Nadu and sent for servicing, elephants returned. For a woman farmer in Maharashtra, crop losses due to wild boars have gone down by 25%. The income of a farmer in Odisha has doubled since elephant invasion stopped.

Ayan says the demand for Parabraksh was more than what his bootstrapped startup could meet, that’s why he decided to raise funds through investors.

It all started with a friend’s SOS call in 2017. “My friend was volunteering with a wildlife organisation in Ladakh. He said villagers were trying to kill the snow leopard that was attacking their livestock. He knew about my background in product design and robotics and asked if I could help,” the 33-yearold recalls.

After a pilot in Ladakh, Parabraksh hit the market in 2020. “Our first taker was a large coffee estate in Kodagu,” he says. About 1,100 units, Rs 9,500 apiece, have been sold since. A majority of the products have been sold to farming and social development collectives in Maharashtra.

“After the show, I am getting enquiries from Kanakapura, Kodagu and Hassan, which see regular elephant movement,” he says.

Monkey chaser

Sensor-based Kapikaat is another product by Katidhan, priced at Rs 5,000 and up. It emits loud sounds to repel monkeys during day time. “It is 70-75 % effective. We reckon that monkeys can get used to the source of the sound and ignore it,” says Ayan.

Hi-Tech Monitoring System For Precise Cauvery Water Data

Telemetric Water Monitoring System installed at Koppa-Kushalnagar Cauvery River Bridge

Kushalnagar:

Amid the ongoing dispute between Karnataka and Tamil Nadu over the sharing of Cauvery River water, a state-of-the-art Telemetric Water Monitoring System, equipped with velocity and level sensors, has been successfully installed on a bridge across the Cauvery River at Koppa-Kushalnagar on the Kodagu-Mysuru border.

This sensor-based monitoring system offers automated and    real-time data 24×7, providing precise information regarding the river’s inflow, water level, and velocity.

The system comprises two sensors: one for monitoring the speed of the water flow (velocity sensor) and another for measuring the depth of the river water (depth sensor).

The installation has been carried out by the Water Resources Development Organisation, a Central Government agency operating under the National Hydrology Project. This organisation has an Irrigation Investigation Sub-Division Office in Mysuru that is overseeing the implementation of this sensor-based water monitoring system. Each system costs Rs. 30 lakh and is imported.

A similar system has already been deployed at Bannur, where the Cauvery River flows and approvals are pending for installing two more systems on Lakshmanatheertha River (near Hunsur) and Lokapavani River in Mandya (a tributary of Cauvery).

This state-of-the-art sensor-based system provides real-time data every 15 minutes to over 15 agencies in Karnataka and at the national level, including the India Meteorological Department, Cauvery Neeravari Nigam Limited and the Karnataka State Natural Disaster Monitoring Centre.

Additionally, the data can be utilised by regulatory authorities such as the Cauvery Water Monitoring Authority (CWMA) and the Cauvery Water Regulation Committee (CWRC) to determine the water allocation between the Southern States.

Speaking to the Star of Mysore this morning, Santhosh Kumar, Assistant Executive Engineer of the Irrigation Investigation SubDivision Office, mentioned that in the past, water flow data collection was a laborious manual process.

The system measures various parameters related to river level and flow, including water height from the stream bed (stream stage), river velocity (measured by a radar-based surface velocity sensor mounted above the river), and river depth and width. The collected data is then transmitted and made available for viewing and downloading.

This system is designed to monitor water levels in rivers, lakes and streams, predict the potential for flooding and issue alerts accordingly. It not only measures water levels but also assesses water velocity, improving the accuracy of risk predictions, Santhosh explained.

The system operates using solar energy and has been installed by Sun Technologies, Chennai, which is responsible for data transmission, system installation and maintenance for five years.

It may be recalled here that a Telemetric Water Gauge has already been installed at the Krishna Raja Sagar (KRS) Dam in Mandya district and at Harangi Dam in Kodagu to provide sensor-based real-time data on reservoir storage levels, inflow and outflow. These installations are part of an Online Monitoring System for the Cauvery Basin, utilising Telemetry-based Real-time Data Acquisition and Transmission.

Coffee Board Launches Soil Testing Centre At Gonikoppal

Mysuru:

Thousands of farmers in South Kodagu now look forward to better yield as Gonikoppal gets a new digital soil testing centre. The Coffee Board launched the testing centre last week following demands of farmers and growers.

Earlier, farmers of Virajpet taluk had to travel 50 to 70 kms to give soil for testing centres at Chettalli and Koodige and both the centres are in Somwarpet Taluk. Farmers in Virajpet were deprived of a testing centre.

Coffee Board Senior Liaison Officer said it took two hours to find the potential of hydrogen (PH) value of soil and five hours to find nitrogen, phosphorus and potassium (NPK) in soil.

Expressing concern over the change in rainfall pattern and temperature in Kodagu, an expert well versed with the hilly district’s ecosystem has suggested that the government should ask research centres to collate rainfall data from farmers’ rain gauges to study the impact of climate change on the district’s ecosystem as well as catchment area of river Cauvery. 

“Kodagu has a practice of almost all the farmers keeping rain gauges in their estates and maintaining daily rainfall data for several decades. The government should ask reputed research centres to get such data from farmers to assess the impact of climate change,” says C.G. Kushalappa, former dean of College of Forestry, Ponnampet and an expert on Kodagu’s ecosystem. 

“The need of the hour is to study and understand the patterns related to impact of climate change on different areas of Kodagu through micro-level data,” he says. This is because the impact of climate change varies in different areas within the small district. Analysis of rainfall data from 110 farmers had showed a pattern of rainfall going below 50% of average two times once in 12 years.

How coffee makes concrete stronger

How coffee makes concrete stronger
Dr Rajeev Roychand (second from left) and his research team have developed a way to use coffee grounds to strengthen concrete by 30 per cent

It can wake you up, it is an anti-oxidant, it is said to be nature’s best pre-workout drink when it comes to burning fat while working out, and now, it can make stronger houses.

No, this writer has not had too much coffee. Just the usual four cups since morning. The last fact mentioned above is supported by scientific research, detailed in a research paper titled Transforming spent coffee grounds into a valuable resource for the enhancement of concrete strength, published in the Journal of Cleaner Production this year. And the lead author of this research paper is Dr Rajeev Roychand, an Australian national originally from sadda Punjab.

Born in the Gurdaspur district, Roychand grew up in Amritsar and moved to Australia in 2005 for higher studies, after completing his Masters in Civil Engineering.

“I was living a carefree life on my father’s hard-earned money, with absolutely no vision for my future,” Roychand tells mid-day through an email interaction. “It was making my father quite anxious. He finally decided to send me to Australia, hoping that I may become serious when I won’t find anybody to pamper me all the time and when I feel the realities of the harsh life.”

The move came as a blessing in disguise for Roychand, who, for the first time, learned the importance of money during his first job at a restaurant.

“The owner called me for a day. It was a very busy restaurant and I worked from 3 pm to 11 pm. without a single second’s break. I worked so hard that the owner of the restaurant asked me to become a regular employee of the restaurant. This extreme hard work was like a sudden shock for me, and I was not mentally prepared to accept this job offer. Seeing that I wasn’t interested, the owner refused to pay me. I went to the station to go back home and cried a lot at the station,” he recalls

Roychand went on to work as a taxi driver till 2008, during which time he also got his citizenship, and then worked as a structural engineer at a private firm. Research, however, was always his calling.

“I was always fascinated by the research field, so in year 2013, I decided to do my PhD at RMIT University, Melbourne,” Roychand says. “The focus of my research was developing a low carbon footprint alternative to the conventional Portland cement.  By the time I completed my PhD in year 2017, I was successful in developing a high durability zero cement concrete utilising different industrial by-products like fly ash, slag, silica fume and some chemical additives.”

The road to Roychand’s Eureka moment in his latest project, funnily enough, started over a cup of coffee, when the research group he is part of at RMIT met to discuss transformation of different waste materials to strengthen concrete.

“We decided to start with coffee waste, taking it as a challenge. We worked on this project for about a year, and finally we came up with a solution that could transform this waste into a valuable additive for strengthening concrete,” he says.

For the benefit of the lay reader, he breaks down the research into simple words.

“Concrete is made up of cement, water, sand, and gravel. In this project, we found that heating spent coffee grounds at 350°C temperature in the absence of oxygen significantly improves its properties. When this treated coffee waste is used as a replacement for sand, it provides a 30 per cent improvement in the strength of concrete,” he explains.

The team, guided by Professor Jie Li and comprising Roychand and his fellow researchers Shannon Kilmartin-Lynch and Mohammad Saberian, Roychand, made their findings public earlier this month, leading to widespread fame. Apart from several research enthusiasts and experts who spoke about the feat, even the official account of the Australian Consulate in India lauded their achievement.

But for them, the most exciting part is that the waste that was ending up in landfills is now ready to be tried out as a high value by-product for construction applications. But that’s not all. Roychand’s research might soon be coming to India, he reveals.

“No doubt, India could immensely benefit from this research. I will be the happiest person if any of my research could benefit my motherland. We are in consultation with one of the companies from India,” he shares, adding, “I still do miss a lot of things, like Amritsari food,  and visiting friends and relatives during festivals. But my world revolves around science,” he concludes.
