Wetland turns a ‘weedland’

Varaalchal, a vast wetland in the flood plain area of the Pampa river at Koipram, near Aranmula, heavily weeded and silted, could do with a few immediate steps for rejuvenation. World Wetlands Day, celebrated on February 2 every year, should serve as a reminder for authorities in this regard.
The once water-rich Varaalchal’s plight has left its immediate surroundings with not less than 2,000 households water-scarce during summer. The 2.5-km-long, 150-metre-wide natural stream, lying between Koipram and Poovathoor, is known for its rich biodiversity, especially the inland fish species of Channa (Varaal as is locally known). Now, this water source is covered with thickets of grass and cabomba weeds.
Pampa Parirakshana Samiti (PPS) general secretary N.K. Sukumaran Nair attributes this sad state of affairs to the drastic depletion of groundwater and lowering of the Pampa riverbed owing to indiscriminate river sand-mining over the past four decades. The lowering of the Pampa riverbed has blocked the water flow between the Varaalchal and the Pampa, except during floods in the monsoon season, says Mr. Nair. K.N. Karunakaran, retired teacher and a local resident, says that fisherfolk who used to eke out a living by inland fishing in Varaalchal are unable to even enter the heavily weeded wetland.
Mr. Nair called upon the State Biodiversity Board as well as the local self-government institutions to initiate urgent measures for the rejuvenation of Varaalchal. He said efforts must focus on the restoration of the natural ability of wetland to detoxify wastes, control floods, restore soil fertility, expunge weeds, purge pollutants, destroy disease-causing organisms, and support a diversity of aquatic and bird lives.
The guidelines of the Ramsar Convention on Wetlands have clearly spelt out norms for conservation and wise management of wetlands. “The Ramsar guidelines state that people are an important part of the ecology and their livelihood is an important contributor to the economy of the region.”
Mr. Nair said cultivation in not less than 500 acres of paddy fields in the close vicinity of the Varaalchal had become a thing of the past.
