The current global freshwater crisis threatens the present and future supply of water as a
resource for humans. The scarcity of drinking water and the dependence of the food indus-
try on water-intensive supply chains require the urgent development of strategies to analyze
and guarantee the water sustainability of countries. This study proposes a fuzzy-data envel-
opment analysis composite index that measures, from a benchmarking approach, water sus-
tainability by simultaneously considering capacity and resilience, and captures the uncer-
tainty associated with time series variations in three scenarios: pessimistic, indifferent and
optimistic. We present and apply an index based on five indicators of capacity and five
indicators of resilience in ten European Union countries water risk hotspots. The results in
terms of capacity presented a higher variability due to the strong growth in the exploita-
tion of water resources in Greece, Spain, France, Italy and Portugal. The most sustainable
countries in terms of capacity were Bulgaria and Estonia in a pessimistic and an indifferent
scenario and France and Bulgaria in an optimistic scenario. In terms of resilience, Belgium
and Portugal were the most sustainable countries. When considering capacity and resil-
ience together, some countries such as Bulgaria and Estonia lost positions in the ranking,
with Belgium occupying the first position. Some countries, such as Bulgaria, could see the
sustainability of their water resources compromised in a scenario of economic develop-
ment if they do not improve their governance and water productivity constraints.
