Balaram Shaw, a researcher at the Interdisciplinary Centre for Water Research in Bengaluru, has led a groundbreaking review that could reshape how industries—particularly the energy sector—plan for water resource challenges in a changing climate. The study, published in *Environmental Research Communications* (known in Hindi as * Paryavaran Anusandhan Sanchar*), examines how climate change and human activities are altering the global water cycle, with surprising implications for water-dependent industries.
Shaw and his team analyzed decades of research on hydrological changes, from rising temperatures to groundwater depletion, and found that in about 70% of studied basins, human activities—such as dam construction, irrigation, and urbanization—have a stronger influence on water systems than climate change alone. This finding challenges the assumption that climate variability is the sole driver of water scarcity, suggesting that local and regional water management practices may play an even bigger role.
For the energy sector, this has immediate commercial implications. Thermal power plants, renewable energy installations like hydropower dams, and even data centers require vast amounts of water for cooling and operations. If human-driven water alterations are more dominant than climate change in many regions, companies may need to reassess their water risk strategies—not just in terms of droughts and floods, but also in how infrastructure itself reshapes water availability.
One key takeaway from the review is the need for better attribution methods. Shaw highlights that while machine learning and statistical models are improving, they still struggle to disentangle the overlapping effects of climate change and human activities. “Current methods often provide a partial picture,” Shaw notes. “We need more integrated approaches that combine process-based models with real-world data to make actionable decisions.”
The study also identifies understudied basins—regions where data is scarce but where water conflicts or energy projects are rapidly expanding. This gap presents both a risk and an opportunity: industries investing in these areas could gain a first-mover advantage by incorporating advanced water attribution techniques into their planning.
Ultimately, Shaw’s review isn’t just a scientific exercise—it’s a call for industries to rethink how they account for water in their long-term strategies. For energy companies, that could mean redesigning cooling systems, diversifying water sources, or even relocating facilities based on more precise hydrological forecasts. The message is clear: understanding the true drivers of water change isn’t just an environmental concern—it’s a bottom-line imperative.
