Sri Lanka Red Cross Society Supports Ecological Restoration of Cascade Tanks in Medawachchiya

The Sri Lanka Red Cross Society, under the Managing Together Project, has commenced an ecological restoration programme in the Medawachchiya Divisional Secretariat Division, focusing on the rehabilitation of 15 traditional cascade tanks.

The Managing Together Project is implemented in collaboration with the Ministry of Environment, GEF, UNDP, IUCN, and the Sri Lanka Red Cross Society. This collective effort promotes a holistic landscape approach that integrates biodiversity protection into agriculture, tourism, and forestry planning in the Malwathu Oya Basin.

The restoration programme involves the removal of invasive and soil conservation measures to restore the natural balance of these ancient water systems. The targeted tanks include Sarakkuwa Wewa, Mahakubuk Wewa, Maguru Hitikada Wewa, Lidahitidamana Wewa, Thulaweliya Wewa, Ihala Wewa, Nika Wewa, Siyabala Wewa, Bogas Wewa, Panak Wewa, Gadol Wewa, Thammenna Elawaka Wewa, Karabe Wewa, and Gurukandegama Wewa.

Sri Lanka’s cascade tank system, a centuries-old irrigation and biodiversity heritage, plays a critical role in sustaining agriculture, wildlife habitats, and rural livelihoods. However, invasive species and land degradation have placed these ecosystems at risk. By working closely with local communities, government agencies, and partners, we aim to restore and protect this invaluable resource.
