Why sustainable agriculture and water sanitization?
The Anuradhapura District has nearly 3,000 main, medium, and small-scale tanks and irrigation work coming from ancient Sri Lankan time from the lead of King Pandukabhaya. During this period, Anuradhapura was considered the most important era in the irrigation civilization in Sri Lanka. Irrigation systems of ancient Sri Lanka consisted of a large number of village tanks to huge reservoirs and an inherent network of water canals linking these tanks whilst supplying water to farming lands. Rice is the staple food of the inhabitants of Sri Lanka. Nowadays the total land dedicated for paddy is assessed to be about 708,000 hectares including a large area of land in Anuradhapura. Mainly there are two cultivation seasons such as Maha and Yala which are identical with two monsoons.
