| Description |
In Sri Lanka, the first complex irrigation systems with underground canals and human-built reservoirs were developed around 2,000 years ago. Since that time, the rulers of Sri Lanka have expanded the system. This infrastructure contributed greatly to the development of agriculture in the country’s dry zone. While the canals are not in use anymore, they still function. One of the science teachers at Mahinda College, Dinesh Tharanga, uses this ancient technology to teach students about modern science. Mr. Tharanga strongly believes that even in the science field, books are not the only valid source of information and that there is strong value in local knowledge. |
