Subak is a traditional irrigation system used in Bali, Indonesia, that dates back to the 9th century. It is designed to manage water distribution for rice fields, ensuring that all farmers in a community receive an equitable share of water. The system relies on a network of canals and weirs, which are maintained collectively by local farmers. The Subak system is not only vital for agriculture but also plays a significant role in the cultural and spiritual life of the Balinese people. It is often associated with the Hindu philosophy of harmony between humans and nature, reflecting the community's commitment to sustainable farming practices.
