Polonnaruwa is a vital region in Sri Lanka's irrigation industry, featuring around 1,500 tanks that date back to ancient times. These tanks, including the renowned Parakrama Samudra, were constructed during the reign of King Parakramabahu I and are crucial for supporting agriculture, particularly rice cultivation in the surrounding paddy fields. The intricate network of tanks reflects the advanced water management systems established centuries ago, essential for irrigation and sustaining local ecosystems.
In the Kubur area, approximately 20 tanks contribute significantly to the irrigation of paddy fields, enhancing agricultural productivity. These water bodies not only support farming but also preserve the cultural heritage of the region, emphasizing the importance of effective water management in sustaining the livelihoods of local communities. Together, the tanks in Polonnaruwa and Kubur highlight the historical significance and ongoing relevance of irrigation practices in Sri Lanka.
