Kerala's Malarikkal water lilies boom, but ecologists warn of ecological harm

A study commissioned by the Kerala State Biodiversity Board has raised concerns over the uncontrolled spread of water lilies in Malarikkal following the 2018 floods. The two-year research documents the lilies' unprecedented growth and their impact on local aquatic vegetation, water flow, and sunlight penetration in the water body.

Ecologists have flagged potential environmental risks, including methane emissions from decaying plant biomass. Meanwhile, the seasonal bloom has made Malarikkal a tourism destination, generating income for local farmers, boat operators, and residents who profit from visitors drawn to the pink flowers.

The findings highlight a tension between the economic benefits the lilies bring to the community and concerns about long-term ecological damage to the region's aquatic ecosystem.
