Water scarcity measures the balance between available freshwater and human or environmental demand, but operational water risk extends beyond a withdrawal ratio alone. A key distinction is that water scarcity, water stress, and water resilience capture different dimensions of exposure because governance, infrastructure, technology, and institutional capacity shape outcomes alongside hydrology. For decision-makers, this framing supports a resilience-based view of water risk that better fits infrastructure, continuity, and investment decisions (UN-Water, n.d.; Verre et al., 2026).
