Proud moment for Shivaji University researchers

Indian patent for portable sound absorption testing device Kolhapur: Researchers from Shivaji University, Kolhapur, have developed a portable sound absorption testing device that can scientifically assess whether an installed sound system and its acoustic treatment are functioning effectively. The innovation has been granted an Indian patent, marking a first-of-its-kind development in this field, the university said on Thursday. The patented device, named the Portable Sound Absorption Tester, has been developed by senior chemist Dr Kalyanrao Garadkar of Shivaji University, along with Dr Sandeep Sable and Dr Rohant Dhabbe of Jaysingpur College, and Dr Chandrala Jatkar of the D K T E Society’s Textile and Engineering Institute, Ichalkaranji. The device is designed to test the sound absorption capacity of professional acoustic systems used in recording studios, theatres, auditoriums and soundproof chambers. Until now, the effectiveness of such sound-absorbing installations has largely been assessed through experience and trial-and-error after installation. The newly developed portable tester allows for immediate and scientific evaluation of sound absorption performance once the system is installed. Sound-absorbing sheets and panels are widely used in theatres, studios and vocal recording rooms to absorb echo around microphones and create a controlled acoustic environment, enabling cleaner and more professional audio output. The new device can be used to evaluate a wide range of absorbers, including perforated foam, fibre, fabric, membranes, panels and resonant absorbers, helping improve the quality and effectiveness of acoustic materials. Explaining the working of the device, Dr Garadkar said that the human audible frequency range extends from 20 Hz to 20 kHz. The device generates sound waves within this spectrum and projects them onto the acoustic material under test. The sound waves that are not absorbed are detected by a microphone and displayed on the screen in the form of current or voltage readings. This enables users to instantly determine whether the sound absorption system is functioning as intended and make corrective interventions if required. The researchers said the device would also be useful for those engaged in acoustic fabrication and sound absorption research. Apart from being portable and easy to transport, the device is also cost-effective, making it suitable for field applications. The team expressed confidence that it would prove highly useful in the sound system testing sector. Shivaji University’s in-charge Vice-Chancellor Dr Suresh Gosavi and in-charge Pro Vice-Chancellor Dr Jyoti Jadhav congratulated the research team on securing the patent.

Marathwada’s Soybean Squeeze

Updated: Oct 21, 2024

For the Shinde-led Mahayuti government, the soybean crisis in Marathwada should serve as a wake-up call as campaigning intensifies ahead of the crucial Assembly election.

In the drought-prone Marathwada region, soybean, a crucial kharif (monsoon) staple, has faced a serious blow this year as a deadly combination of erratic (and unusually heavy) rainfall and soil degradation has led to dwindling yields for farmers already steeped in debt. The crisis has not only deepened rural distress but also dented the political credibility of the Eknath Shinde-led Mahayuti government in the recently concluded 2024 Lok Sabha elections.

Farmers’ frustration, particularly over the low prices and inadequate support, was reflected in the electoral results. Discontent was not limited to soybean farmers but extended to those growing onions and other crops similarly affected by the erratic weather. The opposition parties capitalized on this anger, contributing to the ruling coalition’s losses in crucial constituencies.

Soybean cultivation is central to Marathwada’s agricultural economy with approximately 60% of the region’s cultivable land dedicated to it. However, this year, the area under cultivation fell sharply by 15%, while the yield per hectare has plummeted by nearly 20% compared to previous years.

Discontent among the rural electorate translated into a significant loss of votes for the Mahayuti coalition in the Lok Sabha election, which had counted on Marathwada as a stronghold. Many farmers switched their allegiance to opposition parties, particularly the Congress and the NCP, viewing the ruling government as ineffective in mitigating the crisis.

While promises of crop insurance and subsidies are being made, the delayed rollout of relief measures is aggravating the situation. Farmers are reporting delayed compensation under the Pradhan Mantri Fasal Bima Yojana (PMFBY), India’s crop insurance scheme, which failed to provide timely payouts. To compound the issue, local cooperatives responsible for distributing government aid are being accused of corruption and inefficiency, thereby eroding trust among farmers.

To stem the erosion of its rural voter base, the Shinde government must take decisive action. Strengthening the PMFBY is a critical first step. Insurance payouts need to be streamlined and simplified, ensuring that claims are processed within a few weeks rather than months. The scheme also needs to account for pest attacks and erratic rainfall more accurately, as these are increasingly frequent due to climate change. Enhancing the precision of satellite-based yield assessments would ensure that more farmers receive timely compensation.

Additionally, the government should consider targeted subsidies for soybean growers, particularly for pest-resistant seeds and organic pesticides. A concerted push towards water conservation, particularly through promoting drip irrigation, could help mitigate the impact of future droughts. The state’s ‘Jalyukt Shivar’ campaign, launched in 2015 to boost irrigation in drought-hit regions, could be revitalized, but with greater accountability to ensure funds are utilized effectively.

The state’s past experiments with price stabilization funds, such as the Maharashtra State Agricultural Marketing Board’s attempt to guarantee minimum prices for soybeans, also offer a lesson. While well-intentioned, these initiatives were hampered by poor implementation and market manipulation by intermediaries.

For the Mahayuti government, immediate corrective measures like providing pest-resistant seeds, and reinvigorating irrigation schemes are essential not only to revive the fortunes of the state’s farmers but also to secure the government’s rural support base. Without these, the agrarian distress that continues to plague Maharashtra risks becoming a persistent political liability, as history has repeatedly shown.
