This describe a Study on Building Resilience by combining Ancient and Modern irrigation systems conducted by UNU-IAS in Tokyo, Japan.

Ancient irrigation systems nurtured an advanced hydraulic civilization in Sri Lanka's Dry Zone, where water storage was vital for human existence in the North Central Province. Small-scale village reservoirs and channel systems were initially employed, and the ingenious tank builders utilized the natural terrain to create the small tank cascade system in the valleys.

The dry-zone of Sri Lanka showcases sustainable agricultural systems that have withstood climate variability and societal changes for over a thousand years, serving as essential components in the region's farming sector. However, the productivity of these systems no longer suffices to support the growing population and modern lifestyle aspirations.

To address this challenge, the development of Mosaic Systems is proposed, blending traditional and modern approaches. The Deduru Oya irrigation project presents an ideal research and experimentation ground for integrating ancient and modern irrigation systems. The objective is to enhance cropping intensity, system resilience, and livelihoods for all farmers through increased productivity.
