Answer: Kottayam
Notes: The District Panchayat of Kottayam (Kerala) has formed a technical committee to tackle the water hyacinth problem. Water hyacinth (Eichhornia crassipes) is a fast-growing aquatic plant from Brazil that spreads through seeds and vegetative reproduction. It forms dense mats on water surfaces, blocking sunlight and reducing oxygen levels, which disrupts fisheries, transportation, and recreation. It's often called the "terror of Bengal" due to its invasive nature.
