Abstract. We draw on previous work examining historical trends, likely future water use and food availability in Pakistan and extend the analysis to consider interactions with hydropower generation and the energy demand in food production due to pumping of groundwater for irrigation. Business-as-usual scenarios suggest growing demands for groundwater and energy use for food production as population grows rapidly. However, groundwater use is already unsustainable in many areas, and energy supply is failing to keep up with demand. Quantifying material linkages between water, food and energy provides a means to explore biophysical constraints. Characterising institutional constraints is equally important, as they can be significant barriers to effective stewardship of water, energy and food resources. The experience in Pakistan reinforces this finding, and we discuss the implications for hydrologists.

Short summary
We draw on previous work examining likely future water use and food availability in Pakistan and extend the analysis to consider hydropower generation and energy demand in food production. The biophysical limits of the water-energy-food nexus are just one piece of the picture. We also draw on critical social science and resilience or adaptation-oriented perspectives to consider options usually deemed out of scope for biophysical scientists or water, energy and agricultural authorities.
