Viability of Ulpotha Micro-cascade Rehabilitation with its Indigenous Irrigation Systems-Sri Lanka

The main purpose of this article is to study the viability of Ulpotha micro-cascade rehabilitation with its traditional irrigation system. Rehabilitation of Ulpotha with its natural resources was started on pilot basis in 2005 and completed in the year 2010.

This is the high time to study the impacts of Ulpotha rehabilitation with its traditional irrigation system. Extensive studies on traditional irrigation practices were commenced in 2013 and more positive impacts of the Ulpotha rehabilitation and the use of traditional irrigation were noted.

The traditional irrigation system is more appropriate for this location as paddy is the main cultivation in Yala and Maha. Traditional flood irrigation also supports environment, ecology, biodiversity, agriculture in addition to socio-cultural and religious / spiritual values.
