Notes

  • Vembanad Lake in Kerala is facing a severe infestation of water hyacinth, an invasive weed species.
  • The infestation negatively impacts tourism, inland navigation, fishing livelihoods, and public transport.
  • Water hyacinth growth causes damage to boat propellers, leading to the cancellation of daily ferry services between Muhamma and Kumarakom.
  • The weed also disrupts the movement of agricultural produce in north Kuttanad and affects drinking-water supplies.
  • A one-month pilot project starting September 10 will deploy an unmanned surface vehicle (USV) equipped with a robotic mechanism to harvest the weed.
  • The initiative is led by the State Wetland Authority Kerala (SWAK) and the Centre for Water Resources Development and Management (CWRDM).
  • The Foundation for Environmental Research and Innovation (FERI) is the implementing agency for the project.
  • The project aims to process the harvested water hyacinth into value-added products for local marketing, exploring sustainable management of the invasive species.
