Abstract
Resilience is a key driver for planning adaptation strategies to mitigate
risks due to both natural and anthropogenic hazards. The effectiveness of a
resilience-driven decision-making strategy for adapting systems against
stressors depends on how resilience is mapped to decision variables. This
requires a functional resilience metric, without which it would not be possible
to identify the priority needs for improvement, assess changes, or show
improvement in post-adaptation resilience. In this paper, we aim to contribute
to existing methodologies by proposing a novel model-based resilience
assessment strategy while building on the notion of composite resilience
indicators. Our proposed indicator is functional, reproducible, and is mapped
to adaptation decisions. We propose a framework for integrating the developed
resilience functional form into an adaptation decision-making model. To
illustrate our approach, we use a case study on assessing resilience of On-Site
Wastewater Treatment and Disposal Systems (OSTDS) exposed to risks due to
sea-level rise.
