- Weekends and public holidays are deadly for one of Sri Lanka’s most delicate ecosystems – that is when the island’s 8,815 hectares of mangroves come under threat.
With public officials, forest rangers and NGO workers on holiday, no one is around to enforce conservation laws designed to protect these endangered zones. Except the locals, that is.
Residents of Kalpitiya, a coastal area in the northwest Puttalam District, are no strangers to this phenomenon. Kalpitiya is home to the largest mangrove block in Sri Lanka, the Puttalam Lagoon, as well as smaller mangrove systems on the shores of the Chilaw Lagoon, 150 km north of the capital, Colombo.
Perhaps more important, in a country still living with the ghosts of the 2004 Asian Tsunami, mangroves have been found to be a coastline’s best defense against similar natural disasters.
Many poor fisher families in western Sri Lanka also rely heavily on mangroves for sustenance, with generation after generation deriving protein sources from the rich waters or sustainably harvesting the forests’ many by-products.
But in Sri Lanka today, as elsewhere in the world, mangroves face a range of risks. The United Nations Environment Programme (UNEP) says that the unique ecosystems, capable of storing up to 1,000 tonnes of carbon per hectare in their biomass, are being felled at three to five times the rate of other forests.
Over a quarter of the world’s mangrove cover has already been irrevocably destroyed, driven by aquaculture, agriculture, unplanned and unsustainable coastal development and over-use of resources.
On the west coast of Sri Lanka, despite government’s pledges to protect the country’s remaining forests, the covert clearing of mangroves continues – albeit at a slower rate than in the past.
But a small army of land defenders, newly formed and highly dedicated, is promising to turn this tide.
