A survey by the Centre for Water Resources Development and Management (CWRDM), Kozhikode, has revealed that houseboat operations successful Vembanad Lake person importantly exceeded sustainable carrying capableness limits, with the fig of registered boats astir 200% supra permissible levels.
The report, titled A Study connected the Recreational Carrying Capacity of Vembanad Lake for Sustainable Tourism, submitted to the State Wetland Authority Kerala (SWAK) notes that alternatively of the intended density of 1 houseboat per 20 acres, the existent concern successful Vembanad Lake is person to little than 10 acres per houseboat. “Overcrowding exerts important ecological accent connected the system, making the concern intelligibly unsustainable,” the study observes.
Those registered
As portion of the study, scientists assessed the Recreational Carrying Capacity (RCC) of houseboats successful Vembanad Lake (south of Thanneermukkom barrage), a Ramsar site. As per the RCC, lone 461 houseboats are permissible successful the country astatine a time. However, Port Authority records amusement that a full of 1,625 boats are registered successful Alappuzha and Kottayam, including 821 houseboats. Further, the full fig of houseboats counted by the survey squad done a drone survey successful the country was 926. The discrepancy of 105 vessels betwixt the registered and the counted houseboats is “presumed to correspond those operating without registration oregon licenses.”
The study states that the “current unregulated strategy delivers short-term economical and tourer restitution benefits but results successful terrible biology degradation.” Noting that operational capacities greatly transcend sustainable thresholds, it suggests reductions of 58–80% crossed each vessel types to reconstruct ecological balance.
Legal restrictions
It calls for legally restricting oregon regulating the introduction of houseboats registered extracurricular the Alappuzha Port Registry. “Only vessels registered nether the jurisdiction of the Alappuzha Port Registry and holding valid consent from the Kerala State Pollution Control Board should beryllium permitted to run wrong the Vembanad Lake southbound of the Thannermukkom barrage,” the study suggests. It besides recommends that the moratorium connected caller houseboat registrations nether the Alappuzha Port Registry beryllium maintained until houseboat operations successful the water are streamlined arsenic per the RCC recommendations.
The study further reveals that the mean rider utilisation ratio was 205.2%, indicating that astir houseboats were carrying much than treble their registered rider capacity. “A important 83.5% of vessels were recovered to transcend their ineligible limits, reflecting wide non-compliance with information norms. The highest recorded usurpation reached 850%, underscoring captious information risks wrong the industry.”
To guarantee that houseboat tourism does not lend to the degradation of wetland ecosystems, the study proposes to found a “structured, enforceable, and ecologically dependable garbage absorption plan.”
