Water scarcity has emerged as one of the most critical challenges in Iran, exacerbated by climate change, population growth, and unsustainable water management practices. This paper explores the implications of adopting versus not adopting the Water Footprint (WF) framework in Iran’s national water governance strategies. Drawing on international experiences and Iran’s current hydro-political context, the study employs scenario analysis to assess the environmental, economic, and socio-political consequences of both pathways. The results demonstrate that non-adoption would accelerate groundwater depletion, land subsidence, and food insecurity, with significant risks of social instability and ecological collapse. In contrast, the adoption of WF could foster sustainable water allocation, promote crop diversification, enhance resilience to climate change, and strengthen regional cooperation. The study concludes that WF adoption is not merely a technical measure but a governance transformation, essential for securing Iran’s long-term water security and socio-economic stability. This research contributes to the broader discourse on sustainable water management in arid regions, offering a framework for policymakers to transition from crisis-driven management toward proactive resilience.
