In the lush, verdant landscapes of Bali, where traditional irrigation systems have sustained agriculture for centuries, a modern challenge looms large: the water crisis. As climate change intensifies and water use conflicts escalate between upstream and downstream areas, communities reliant on the ancient Subak irrigation systems are feeling the strain. A recent study published in the *Prima: Journal of Community Empowering and Services* (translated as “Journal of Community Empowerment and Services”) offers a promising solution to this pressing issue, with implications that could ripple through the energy sector and beyond.
At the heart of this research is I Gusti Agung Putu Eryani, a civil engineering expert from Universitas Warmadewa in Denpasar, Bali. Eryani and her team have been investigating the water shortages plaguing Subak Balangan and Uma Tegal in Desa Kuwum, Badung. The problem is twofold: inadequate irrigation channels fail to retain water during the rainy season, leading to droughts in the dry season. “The lack of water storage infrastructure exacerbates the water crisis, impacting agricultural productivity and the livelihoods of farming communities,” Eryani explains.
The solution? Water reservoirs. These structures serve as rainwater reservoirs, ensuring a steady water supply throughout the year. By implementing reservoirs, Eryani and her team have demonstrated a significant improvement in water availability for irrigation, reducing flood risks, and providing ecological and economic benefits. “Reservoirs can stabilize the water supply, enhance agricultural productivity, and support the economic well-being of local communities,” Eryani states.
One of the innovative aspects of this research is the use of geomembranes in the reservoir construction. These synthetic liners improve water storage efficiency, preventing leaks and ensuring that every drop of rainwater is put to good use. This technology, while not new, is a game-changer in the context of traditional irrigation systems. “The integration of geomembranes with traditional Subak systems is a testament to the power of blending old and new technologies,” Eryani notes.
The commercial implications of this research are substantial. In the energy sector, water is a critical resource for power generation, particularly in hydropower plants. As water scarcity becomes a global challenge, innovative solutions like these reservoirs could help secure water supplies for energy production. Moreover, the economic benefits of enhanced agricultural productivity cannot be overstated. By ensuring a stable water supply, farming communities can increase their yields, boosting local economies and contributing to food security.
The study also underscores the importance of wise reservoir management. This includes water quality monitoring, environmental impact mitigation, and active community participation. Eryani emphasizes that sustainable water management is a collective effort. “Community involvement is crucial for the success of any water management initiative,” she says. “It ensures that the solutions are tailored to the local context and that the benefits are shared equitably.”
As the world grapples with the realities of climate change and water scarcity, research like Eryani’s offers a beacon of hope. By integrating traditional knowledge with modern technology, we can develop sustainable solutions that support both people and the planet. The energy sector, in particular, stands to gain from these innovations, as secure water supplies are vital for power generation and other industrial processes.
In the face of a global water crisis, the lessons from Bali offer a blueprint for action. By investing in water infrastructure and fostering community engagement, we can build a more resilient and sustainable future. As Eryani’s research shows, the path to sustainability lies in the wise use of our most precious resource: water.
