Access to water is a defining feature of civilization. The quest to channel water for drinking, and agriculture precedes settled societies. Today, the world is facing water stress, and increasing extreme events.
80% of all extreme weather events
are water related.
Water infrastructure is needed to manage three flows: fresh water, waste water, and storm water
Fresh water is used for drinking, agriculture, and industry with varying thresholds of quality. The waste water streams process the discharge post consumption for safe return to the water cycle. Different infrastructure assets such as dams, reservoirs, pumping stations, piping, canals, water purification plants, water filtration plants, and waste treatment plants form a complex web of in the water infrastructure system.
The climate threats from extreme events, cause physical damage to these assets, and disrupt services. Losses due to physical damage, and with changes in supply/demand are projected to increase. In the face of these events, adaptation becomes primary objective. The way to adapt to these events is to build grey infrastructure, but these solutions are limited to changing climate.
Inclusion of green-blue infrastructures are crucial to improve the overall resilience of the system. Not only climate adaptation, but it also contributes to climate mitigation through carbon sequestration, and addresses the biodiversity decline as well. Every infrastructure development has to include increased resilience standards, through development and retrofit existing assets with blue-green infrastructures.
A nature based resilience platform offers practical solutions to integrate blue-green infrastructures and mitigate climate risk to infrastructure assets.
