| Summary: | Water systems are a special kind of
infrastructure systems because they perform a dual role:
theyprovide water services while also reducing risks to
other services from natural hazards such asfloods and
droughts. This report aims to inform water system managers
on the importance of andmeasures to build the resilience of
water service provision to natural hazards and climate
riskswhile ensuring that water systems can safeguard service
provision by reducing their exposure tothe risks associated
with natural hazards. When choosing resilience measures,
water systemsmanagers should consider the following six
principles while also incorporating the concept ofdecision
making under deep uncertainty: 1) knowing the system through
network analysis andcriticality assessment; 2) improving
maintenance to reduce vulnerability and improve
resilience;3) involving users for active demand management;
4) working with nature to manage and respondto risks; 5)
developing and improving contingency management; and 6)
applying innovation whereappropriate. In addition, since
water systems reduce the risks associated with certain
naturalhazards to other services like power, transport and
water itself, such safeguard services shouldbe accounted for
when making the case for resilience investments in water systems. |
