Climate shifts to reshape Pakistan’s Lower Chenab Canal water-energy future

A new study by Mudassar Anwar Butt, from the Department of Irrigation and Drainage at the University of Agriculture Faisalabad, projects significant shifts in temperature and rainfall patterns in Pakistan’s Lower Chenab Canal (LCC) command area—a critical agricultural and water management region. The research, published in *Discover Environment* (*Kashf-e-Muheet*), uses the Statistical Downscaling Model (SDSM) and Environment and Climate Change Canada’s CanESM2 General Circulation Model (GCM) to analyze future climate scenarios under Representative Concentration Pathways (RCPs) 4.5 and 8.5.

The findings suggest that by the 2080s, mean annual minimum temperatures (Tmin) could rise by 1.06°C under RCP8.5, while maximum temperatures (Tmax) may increase by 0.59°C. Seasonal variations reveal even sharper changes: spring Tmax could climb by up to 3.33°C, while summer Tmax might dip slightly under both scenarios. Rainfall projections indicate a dramatic rise—up to 65% by 2080s under RCP8.5—with winter seeing the most pronounced increase (106% under RCP8.5 by the 2020s).

These shifts carry profound implications for water and energy systems. As Butt notes, “The projected changes in temperature and rainfall will disrupt cropping cycles and strain water availability, forcing utilities and agricultural planners to rethink irrigation, drainage, and energy demand forecasts.” Warmer winters and wetter springs could accelerate crop evapotranspiration, increasing irrigation needs and power consumption for pumping. Conversely, reduced summer temperatures might temporarily ease cooling demands but complicate peak hydropower generation.

For the energy sector, the study underscores the urgency of climate-adaptive infrastructure. Grid operators may need to plan for higher summer cooling loads and variable hydropower output, while water managers must prepare for intensified drainage challenges during wetter seasons. The findings provide a data-driven foundation for policymakers, utilities, and agricultural stakeholders to align energy and water strategies with evolving climate realities.

As the paper concludes, “These future climate changes might have a negative effect on agriculture and water resources in LCC command area, temporally and spatially.” The research, rooted in rigorous downscaling techniques, offers more than just a forecast—it’s a call to action for sustainable, adaptive resource management in South Asia’s breadbasket.
