|Rice field in Bali, Indonesia|
But along with the times, as well as changes in lifestyle and needs, now increasingly threatened the existence of Subak. Subak sustainability as a world cultural heritage threatened by the rapid development and the need to support tourism. Sale of land and water become the most vital factor in the preservation of Subak.
Here are the factors that threaten the existence of Subak in Bali:
- The use of harmful chemicals as pesticides that affect soil fertility. Farmers increasingly difficult to restore soil fertility for organic farming needs, because the land has already chemicals to fertilize the soil for many years.
- Tourism is causing fragmentation Subak rice field terraces, thus increasing the rate of sale of agricultural land and eliminate the unity of landscape, the land with one another, thus speeding up the transfer of agricultural land conversion in a place into shopping complex, housing, villas, hotels, and shopping centers.
- Water quality is declining as a result of the rapid development in the upstream region and the loss of forest area were converted into new agricultural land.
- The potential for the occurrence of natural disasters, including earthquakes and landslides, causing changes in the landscape and waterways, because Bali is formed from volcanic eruptions.
- Climate change can affect the cycle of the seasons and changes in the frequency of rainfall, rainfall is increasingly rare, or vice versa, so that the growing seasons can not be determined with certainty.
Although it has been since the year 2012 be declared Subak Cultural Landscape World Heritage Site by UNESCO, but until now the cultural heritage site management model is still being sought and formulated. In contrast to the cultural heritage of the dead, then Subak is a living cultural heritage, dynamic on the one hand, but if not maintained properly will turn into damaged or lost.
