0 Better water management needed to avoid crisis

Massive developments in Bali have had a serious negative impact on the island’s water resources, which are now running short in many places, an expert stated. I Nyoman Sunarta, a hydrologist and senior researcher at Udayana University’s Center for Environmental Education, shared with Bali Daily last weekend that a number of strategic policies had to be implemented immediately to protect the island’s critical water supplies. “Water supplies during the rainy season are abundant, but during droughts, in some parts of Bali water is scarce. Therefore, we need smart and sustainable strategies to manage our precious water resources,” he said.

Planning, developing, distributing and managing the optimum use of the island’s water resources were needed to allocate water on an equitable and sustainable basis, he added. Reforestation and re-greening programs in the upstream water catchment areas would be one of the most important strategies. “Our forests have been diminishing due to illegal logging, as well as the development of concrete structures for tourist facilities,” he said. Sunarta elaborated that Bali had been facing a water deficit for the last few years due to a variety of reasons, such as long dry seasons, large-scale and uncontrolled development programs, inefficient water management and other man made and natural causes.

The island’s water supplies were influenced by three factors — rainfall, water flow and area. Bali currently has only 4.7 billion cubic meters of water available every year, while the real annual demand for water reached 5.4 billion cubic meters. It is estimated that Bali’s water deficit will reach 27 billion cubic meters by 2015, and the island is predicted to suffer from a serious water crisis. Meanwhile, forested areas, with their important water catchment function, have been falling significantly for years. It is estimated that 23,000 hectares, or 18 percent, of the island’s 130,000 hectares of forest reserves are in critical condition and need prompt rehabilitation.
The forests are being converted into plantations and residential areas. Ongoing tree cutting and illegal logging has also worsened the remaining forests’ condition. The provincial administration claimed that it had rehabilitated 13,000 hectares of the damaged forest. Wayan Darma, head of Bali Forestry Office’s land rehabilitation and community forest department, said that 9,000 hectares of forest in Buleleng regency and 5,500 hectares of forest in Karangasem had been damaged due to forest fires, landslides and illegal logging. “Topographically, Bali consists of mountainous and hilly land. Forests are important to prevent the land from eroding and flooding,” Darma said.

Darma also added that several areas in Bali, such as the Mount Batur area in Bangli, and Mt Agung and Mt Abang in Kintamani, were in critical condition due to damaged forests with the reduced ability to protect the area from various natural and manmade disasters. The forests in those areas are the island’s major water catchments. Jembrana in West Bali and Buleleng in North Bali have 62 percent of the total forests in Bali. In addition to the declining amount of forest, Bali is also facing other land problems. Klungkung regency, for instance, has 13,800 hectares of critical dry and arid land, while Karangasem regency has 10,600 hectares of land in poor condition.

Badung regency, in the south, also has 500 hectares of drought-prone area in Jimbaran. Sunarta said that Bali had already been applying sustainable water management systems for centuries, but these traditional ways were being abandoned. Among the sustainable water management systems are the subak agricultural system, as well as rituals to worship water and plants. “Those traditional rituals and agricultural systems are still relevant to modern lives, but many people tend to ignore them, leaving Bali in the hands of investors,” he said. “Bali has the traditional wisdom to preserve its precious water resources, we have to continue paying respect to our own cultural traditions to protect our water,” he declared.
