cross dependency initiative  
integrated risk & collaborative adaptation




XDI stands for Cross Dependency Initiative. The Cross Dependency Initiative recognises that critical infrastructure is highly interdependent and requires other supporting infrastructure in order to function.

Critical infrastructure crosses ownership boundaries such as utilities, government and the private sector.  When assessing risk from climate change and extreme weather, an infrastructure organisation will find a reliance on an upstream or sideways organisation that affects the risk profile. This is called integrated risk; a risk that is shared with another party. In order to assess and mitigate integrated risk, all related organisations must be considered as a system.

Without a system-wide view, the ability to contain business disruption and assure climate resilience is limited.  XDI engages multiple parties across multiple sectors, in a single quantitative system, to develop a cohesive outcome

XDI allows infrastructure organisations to assess their integrated risks, and build collaborative adaptation strategies with other vested interest parties.


XDI helps businesses optimise adaptation planning and future investment in infrastructure solutions.  XDI enables more integrated planning between utility managers, helping them to understand the interdependencies within their supply chain. 



AdaptInfrastructure is the basis on which XDI works.  Developed by Climate Risk, AdaptInfrastructure is a sophisticated stochastic risk quantification tool, leveraging Cloud based software using GIS, weather, engineering and financial data.

AdaptInfrastructure analyses large numbers of assets for:

  • extreme weather and climate change risks
  • annual average damage costs
  • impact diagnostics per asset  
  • quantification of disruption of people and businesses.

AdaptInfrastructure then provides an adaptation cost-benefit-analysis, comparing capex of adaptation actions with saved opex on losses or insurance (cash-flow and NPV).

The tool has grown from the original AdaptWater software which was developed to serve water utilities, and now has broad capability to analyse multiple asset/infrastructure classes including roads, water and power utilities, structural infrastructure such as ports and airports, buildings, and biodiversity (parklands).

AdaptInfrastructure has multiple visual communication capabilities to demonstrate  project outputs. 

The heat map visualisation above shows assets as circle outlines.  The change in colour represents increase in risk cost as time increases, with blue representing less costs and green / yellow representing high costs.


The images below are sample outputs taken from XDI analysis, using AdaptInfrastructure.  Text in the right hand column provides further explanation.

Risk Costs :  The system provides a breakdown of the annual average costs of damage and losses from each hazard.  The perturbations in the lines give an insight into the statistical monte carlo engines that drive the system.


Diagnostics : The unique capability of AdaptInfrastructure is its ability to diagnose vulnerability.  This graph shows the parts of the asset that can fail due to extreme weather events to which it is exposed.  In this case the Civil components are vulnerable to forest fire damage. Also, the Electrical, Electronic and Mechanical systems can fail due to both riverine flooding and extreme heatwaves that exceed design tolerances.  The cost of damage adjusted for the probability of each of these events occurring in in the target year are shown.

Comparing Adaptation Plans  This graph compares the progress of risk over time  when a multi-stage adaptation plan is implemented.  The system also calculates the discounted 'present value' (PV) of risk specifically for financial managers and tables of Net Present Value are also available to find which adaptation plan represents best value for money..




SOAR Report

The State of Asset Resilience (SOAR) Report is an annual  summary of the resilience of the organisations assets and the projected trajectory of the portfolio - which could be deteriorating due to climate change or improving due to planned adaptation actions.

SOAR reports are excellent for highlighting emerging problems and benchmarking across the business.  You can download a SAMPLE SOAR report  to give you can idea of the report content and structure.


We are currently deploying the XDI technology in projects in three Australian States- New South Wales, Victoria and Queensland.  This will include the world’s first city-wide climate cross dependency model for Sydney.  Partners include City of Sydney, Office of Environment and Heritage, Roads and Maritime Service, Sydney Trains and Sydney Metro

In 2017 the XDI technology is also being trialled at a national level in Fiji, Samoa and Papua New Guinea.
