There is an increasing societal emphasis being placed on the concept of resilience – and, in particular, on addressing the dual challenges of climate risk in terms of the transition to a low carbon economy and adapting to acute and chronic physical threats such as sea level rise.
While there continues to be much emphasis placed on decarbonisation, electrification, renewables and alternative fuels, the latest IPCC AR6 report and the outcomes of the negotiations at the recent COP26 indicate it is likely now a shortening window of opportunity for organisations to address climate resilience issues before these physical impacts from climate and extreme weather become more serious. Reporting and regulatory requirements around climate risk financial disclosure are also emerging, with TCFD reforms being implemented by national governments and stock exchanges across many jurisdictions.
Despite these considerable drivers of change, the requirement for assessing climate resilience remains discretionary mainly. Organisations' current action is primarily driven by investor and corporate ESG aspirations rather than operational risk and regulation.
Because they are situated in current, and future hazard areas, increasing physical risks from climate will be felt keenly by maritime infrastructure owners and operators (across ports, harbours, marinas and shipyards). These facilities will invariably be exposed to increasing climate-related risks, given their proximity to the coast and waterways.
As shown in the figure, this will play out in the form of acute impacts such as storms, heat waves, and flash flooding but also much more gradual climate changes such as sea level rise, temperature increases and drought affecting water supply, increased sedimentation (leading to more frequent dredging) and changes to wind dynamics potentially affecting maritime navigation.
As climate's current and potential future impacts become better understood, many maritime sector organisations are starting to take their first steps toward resilience and adaptation planning.
In our experience, while the resilience planning process should be evidence-based, it need not be an excessively costly or time-consuming exercise. Some opportunities here include:
However, bespoke site-based assessments remain a critical tool for owners and operators to understand and discuss the consequence of these trends at the local scale. This level of detail becomes vital for organisations to accurately assess the potential implications of climate on business operations (including costs), their organisational tolerance to these risks over time and priorities for action.
For a modest investment, this information can inform the aspects and areas of existing vulnerability to climate change that need priority treatment and guide the siting and design of future development and expansion.

Ports, marinas, harbours, and shipyards face many challenges regarding the risks associated with climate change and extreme weather.
Many cities and urban settlements are getting denser as more people move from rural areas. Current projections indicate that 2-3 billion more people across the globe will be living in cities by 2050.
As we close off on another National Water Week in Australia and anticipate COP 26 in the UK starting in early November, it is an excellent time to check in on the consideration of climate risks and resilience as part of water supply planning, asset management and operations including the implementation of water efficiency measures.
There is an increasing global need to transition from fossil fuels to renewable energy, which, combined with a demand for increased aquaculture production, means there is massive potential to do more in the blue economy sector.
