A study on the impact of the flood in 2018 on land use in Achankovil river basin shows that the flood has damaged a total of 28.15% land use of the area fully or partially.
By comparing land use maps before and after the flood, the study said the mixed crops faced the highest damage of 61.81%, paddy fields 14.79%, fallow lands 14.76% and settlements with mixed tree crops 5.92% loss.
Loss of land use occurred from upstream Achankovil to downstream Veeyapuram area. Proper protection of river bank by vegetation like bamboo is needed for the sustainability of the ecosystem as they support the river bank by preventing the landslide and bank erosion.
