Blue Line ACs, ventilation system to undergo 500cr overhaul after 40 years
1 2 Kolkata: Metro Railway has decided to pump Rs 500 crore to revamp the four-decades old air-conditioning and ventilation system between Rabindra Sarobar and Belgachhia stations in the North-South or Blue Line. There are 15 underground stations in this line. Sources said the tendering for overhauling the environmental control system (ECS) or the air-conditioning system for 15 stations dotting the 16.9 km section from Rabindra Sarobar to Belgachhia that has been floated will also include replacing the AC and ventilation of the twin tunnels. "The work is mainly aimed at ensuring cooler stations and tunnels. It will also improve the fire safety system, making sure there is proper ventilation inside the tunnels when a fire breaks out and passengers need to be evacuated," a source said. He said the air-conditioning and ventilation will be upgraded in accordance with the current ambient temperature, which has risen considerably since metro first started operations around 40 years ago. The 15 underground Blue Line stations have centralised air-conditioning systems which include water-cooled chillers, towers, coils, and ducts through which cool air is released into the platform, concourse, and mezzanine levels. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Man Saves Pennies For 45 Years Despite Warning Undo "These are now considered primitive. They will have to be replaced with modern heating ventilation and air conditioning (HVAC) systems," an official said.

Over the years, it expanded north and southwards across the city's central axis. The southern terminal station at New Garia, Kavi Subhash, was shut down on July 28, when cracks were spotted on the columns supporting the Dakshineswar-bound or Up platform. Truncated operations are run till the second last southern station at Dhalai Bridge, Shaheed Khudiram. Metro Railway announced that the Kavi Subhash station will be rebuilt. The tender process is likely to end this month, following which the lowest bidder will start the work. Sources said the work will take at least four or five years to complete. "The work will be done while the commercial operations continue uninterrupted. Therefore, work will take time, unlike greenfield projects," a source said. Surface stations like Dum Dum, Noapara, and those between Mahanayak Uttam Kumar (Tollygunge), Shaheed Khudiram, and Kavi Subhash (New Garia) don't have cooling units. Officials said the basic design of North-South Metro, done by IIT-Kharagpur, was advanced, but the various equipment used in the metro system need upgradation and replacement due to the passage of time. Keeping this in mind, Metro Railway engaged RITES to conduct a health study.

Marine fish landings in Andhra Pradesh decline amid heatwaves & cyclones
Visakhapatnam: Andhra Pradesh recorded 1.75 lakh tonnes of marine fish landings in 2024, marking an 8% decline from 2023 and a 19% drop from 2022. Notably, Indian mackerel was the most landed species in Andhra Pradesh at 32,490 tonnes, a surge of 76% compared to 18,490 tonnes, representing the highest landing in the past decade. Penaeid shrimp secured the second position with 12,320 tonnes landed. Meanwhile, Lesser sardines maintained their third-place ranking, showing a modest 3% recovery after a steep 72% fall in 2023. This trend was mirrored nationwide. India's marine fish landings experienced a marginal decline of 2%, decreasing from 35.3 lakh tonnes in 2023 to 34.5 lakh tonnes in 2024. The overall downturn was driven by reduced landings along the West Coast, whereas the East Coast saw growth. These were some key findings of the ICAR-Central Marine Fisheries Research Institute's annual report 2024. Despite the decline in quantity, the value of marine fish landings in Andhra Pradesh was estimated at Rs 3,176 crore, reflecting a slight increase from Rs 3,162 crore in 2023. Similarly, at the retail level, the value of fish landings rose to Rs 4,507 crore from Rs 4,456 crore the previous year. Across India in 2024, marine fish landings were valued at Rs 62,702 crore at landing centres and Rs 90,104 crore at retail centres, registering increases of 4.22% and 8.46%, respectively. Within Andhra Pradesh, Kakinada district contributed the largest share at 40%, followed by Visakhapatnam at 22%. The newly operational Juvvaladinne fishing harbour in Nellore, which commenced operations in June 2024, accounted for 3% of landings among major harbours. According to the CMFRI report, environmental factors played a significant role in the decline of fish landings in Andhra Pradesh, with increased heatwave days and cyclones (Dana in Oct and Fengal in Nov), leading to notable drops in fourth-quarter catches. The rise in heatwave days, coupled with frequent weather disturbances in the Bay of Bengal, exacerbated the impact of these cyclones on both livelihoods and marine productivity. Turning to marketing efficiency, measured as the fishers' share of the consumer's rupee (FSCR), this varied across states for major species. Kerala recorded the highest efficiency at 71.59%, followed closely by Andhra Pradesh at 70.48% and Daman and Diu at 70.05%. In terms of fishing methods, multiday trawlers accounted for the major share of estimated landings in Andhra Pradesh at 47%, followed by motorised gillnetters (20.2%) and motorised ring seiners (19.9%). Other significant contributors included motorised hook and lines and non-motorised gears. Catch rates for single-day trawls reached 83 kg/hour, marking a significant increase from the previous year. Multiday trawls also saw an improved catch rate of 43 kg/hour. The highest catch per unit effort was observed in ring seines (886 kg/unit), followed by motorised hook and lines (380 kg/unit) and motorised gillnets (156 kg/unit). Artisanal (non-motorised) fishing gears had a catch rate of 91 kg/unit. An economic analysis of mechanised multiday trawlers was carried out by CMFRI for the Kakinada and Visakhapatnam harbours. In 2024, the average operating cost of a mechanised multiday trawl net in Kakinada was Rs 1,67,005, with an average gross revenue of Rs 1,91,117. Similarly, at Visakhapatnam, the operating cost was Rs 2,12,968, with average gross revenue amounting to Rs 2,31,669. For motorised single-day trammel nets and ring seines in Srikakulam district, the operating costs were Rs 30,675 and Rs 24,946 per unit respectively, with average gross revenues of Rs 59,242 and Rs 45,658. Non-motorised single-day gillnets in Vizianagaram district had an operating cost of Rs 4,631, generating an average gross revenue of Rs 9,165. It is noteworthy that the capital productivity of single-day fishing using non-motorised gillnets was efficient, with a lower operating ratio of 0.51 compared to other craft-gear combinations. Capital productivity ranged from 0.51 for non-motorised gillnets (single-day fishing) at the Bavanapadu landing centre in Srikakulam district, up to 0.88. Gross value added was highest for non-motorised gillnets operating in Srikakulam district, reaching 99%.

Five years since formation of Tadigadapa municipality, Kanuru lacks basic amenities
Vijayawada: Basic amenities like CC roads, side drain canals, and bus stops are still a work in progress in the Kanuru locality, even five years after the formation of the Tadigadapa municipality. In December 2020, four major panchayats including Kanuru, Poranki, Tadigadapa, and Yenamalakuduru were merged to form the Tadigadapa grade-1 municipality. The Tadigadapa municipality has an annual budget outlay of approximately Rs 60 crore. The municipality does not receive any special grants from the Centre and the state govt as it lacks an elected council and is ruled by a special officer with the municipal commissioner as its head. The municipality has a population of 2.15 lakh and is witnessing rapid growth with major commercial, educational, and residential units coming up in the region. "Five years have gone by, CC roads, drain canals, and underground drainage system (UDS) are still a distant dream for many residents residing in the Kanuru area. Previously, officials did not even listen to our problems. Now, the newly appointed commissioner and MLA have promised to address our problems in a phased manner," says Srinivas, a resident of the Kanuru area. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Treatment That Might Help You Against Knee Pain Knee pain | search ads Find Now Undo "The road leading to Kanuru from the Vijayawada-Machilipatnam highway is completely worn out with overflowing drains," Srinivas said and added that the reason for such a situation is because no proper road was laid after Kanuru was merged into Tadigadapa municipality. The municipal authorities stated that Kanuru main road falls under the jurisdiction of the roads and buildings (R&B) department and the municipality is not the competent authority to take up road works. "However, the municipality has filled the potholes with dust, thus providing temporary relief," Tadigadapa municipal commissioner Sk Nazeer said. Nazeer told TOI that the municipality identified all the works required to be taken up and would execute them on a priority basis as the municipality does not have adequate funds to take up development works. "Recently, the AP Capital Region Development Authority (CRDA) promised to allocate Rs 9 crore funds in a phased manner to the municipality. To utilise the CRDA funds in an effective manner, the municipality identified 26 prominent works for which tenders will be called soon," he added. He said the CRDA collects development charges while issuing permissions from layout and apartment developers and agreed to extend Rs 9 crore for executing development works in the municipality. Meanwhile, another citizen, 50-year-old Rambabu, pointing to the drain on the Shamrock School and PVP Engineering college road, said: "The lack of a protection wall along the drain poses a serious threat to motorists as there is a high possibility of vehicles veering off the road and falling into the drain, as the narrow road cannot accommodate two-way traffic when heavy vehicles enter the road. Rambabu, who daily drops his daughter to the school on his two-wheeler, fears some untoward incident might happen and urged the authorities to close the drain at the earliest. He also demanded the authorities to install speed breakers near the Petrol Bunk towards Enikepadu stretch on the 100-feet road, as at least one minor mishap is reported daily.
