Subak Catur Angga, one of the World Cultural Heritage (WCH) according to UNESCO, has been known as a local rice producer in Bali. Local knowledge that is still believed, environmental and climatic conditions make local rice still exist today. "I have felt, for maintenance between local and superior rice [GMO], it is easier for local ones," said Wayan Watera, Pekaseh Subak Keloncing.

Farmers in Subak Keloncing, Tabanan prefer to grow local paddy rather than paddy from prime seeds from the industry. Wayan Watera–Pekaseh Subak Keloncing–said, "We ever plant prime seeds in the past, because some people said we can harvest it faster, but it turned out that the difference was 15 days from local paddy." Of hundreds of farmers included in Subak Keloncing, just a few have planted prime seeds in half of their lands. "I've felt the difference between local and prime seeds, especially in maintenance. For me, growing local seeds is easier. And it has the same result. That's why farmers here are less interested in prime seeds," added this 72-year-old farmer.

The existence of Subak as part of World Heritage by UNESCO is in danger of being revoked. Moreover, Its environment is also threatened due to ecological problems, such as land conversion, water exploitation, and soil degradation. In response to these problems, the Group of Pekaseh[leader] Subak Catur Angga held several meetings and decided to make a Working Group (Pokja) in early 2020. "Through this Working Group, we hope to produce an agreement based on our needs in the future," said Ketut Suastika, PekasehSubak Catur Angga Working Group supervisor.

Beyond expectations, the trial of implementing healthy and eco-friendly agriculture in an area of 10 acres in Subak Catur Angga, Tabanan, resulted in a satisfying harvest. 

Every year Subak has been decreasing in line with the shrinking water resources in Bali. “After 2015, in my area [Subak Uma Lebah, Petulu Village] the water debit began to decrease and dry land increased by one hectare every year,” said Kadek Suardika in the Bali Water Protection’s webinar “The Role of Subak in Water Resources Conservation” on Friday, 27 August 2021.
