The storms arrive harder, the dry spells last longer, and cities grow faster than pipes and policies can keep up. This is the context in which global water security will rise or fall. For utilities, regulators, and engineers, the question has shifted from whether climate change matters to how to design systems that can adapt to it. The opportunity is sobering but real.
If science is linked to community knowledge, and finance to fair governance, fragile supply lines can be transformed into resilient ones. Australia has something distinctive to offer, drawn from decades of hard lessons in scarcity and variability.
Water is often described as the great connector, shaping agriculture, health, energy, trade and ecosystems in equal measure. When supply falters, the ripple effects spread beyond a single utility or community. Partnerships provide the glue that holds these interdependent systems together. Australia’s experience in dealing with scarcity shows that long-term collaboration between governments, industries and researchers can stabilise fragile systems and guide reform. This experience is not a template to be copied, but a set of lessons that can be shared, adapted and refined with partners across the Indo-Pacific. For many communities, that exchange means the difference between resilience and decline.
Why global water security needs partnerships
“Partnerships do not happen just because people want to work together,” Sarah Ransom said. “There is a whole lot of science and practice around how you broker them so they succeed.”
Ransom’s career explains why she values this skill. She began her career as a lawyer and diplomat, was trained as a mediator, and worked on peace processes before transitioning to development partnerships. That background gave her a practical appreciation for justice, power dynamics and co-design, lessons she now applies in the water sector.
Ransom leads the Australian Water Partnership, a DFAT-funded program implemented by the eWater Group, which mobilises Australian expertise for the Indo-Pacific.
“Climate change is now everywhere in the work,” she said. “Too much water, too little water or water of the wrong quality is the familiar story, but we are also seeing water’s role in mitigation through methane and wastewater management, and in resilience for communities and ecosystems.”
The second driver is urbanisation. Growing cities strain pipes, treatment and planning, while rising living standards increase industrial and agricultural demand. Global water security cannot be solved system by system. It needs alliances that span utilities, basin agencies, health, energy and data policy.
“We are seeing new questions at the water–energy–data frontier,” Ransom noted, pointing to the water demands of hyperscale data centres and the energy transition.
From World Water Week to action
At World Water Week in Stockholm, the theme “water for climate action” placed global water security at the centre of both adaptation and mitigation. Ransom and her team supported the Indigenous peoples’ focus. They joined a sunrise swim celebrating the first United Nations World Lake Day, a reminder of why clean, swimmable waters matter to people as well as policy.
“The urgency stepped up this year,” she said. “Funding is tight, but the energy to work across sectors is growing. Young leaders are bringing ideas and momentum that the sector needs.”
Looking ahead, Australia and Pacific partners have bid to co-host COP31 in 2026. If successful, that gathering will put water for climate action on a practical stage for the region. For organisations tracking global water security, it presents an opportunity to translate session rooms into project pipelines.
Australian partners in the field
Global water security is not abstract for Australian firms and agencies already working with AWP.
WaterAid brings WASH delivery experience and sector strengthening in low-income settings.
CSIRO contributes basin-scale science, including integrated studies in Bangladesh.
GHD provides design and advisory capacity across utilities and infrastructure.
The Bureau of Meteorology supports forecasting and water assessments that underpin decisions. Universities, such as the University of Melbourne, incorporate policy and management research.
The Australian Water Association connects this community through programs from Vietnam to the Pacific.
Ransom also points overseas partners to Australia’s lived experience. Drought management, operating under extreme variability, and two decades of Murray–Darling Basin reform resonate with peers.
“We try to be humble. There is still work to do, including with First Nations engagement,” she said. “But the integration of science, economics, politics and community engagement in basin-scale reform is of real interest internationally.”
Utilities are noticed too, from circular economy projects to credible net-zero pathways.
Skills, finance and the road ahead for global water security
Practical partnering skills are now strategic. Ransom and her team are renewing AWP’s 250-plus partner network, opening regular calls for proposals, and investing in long-term country relationships so activities are co-designed and measured for impact. The program is entering Phase 3 under eWater’s management after an open re-tender, with a brief to deepen climate integration and pursue a more sustainable funding footing.
“Global water security is also a literacy issue,” Ransom argued. “Australians do not always see the skill, planning and care that keep their taps running. If water links to the climate agenda in a way people feel, we can build the mandate for investment.”
She added that inclusive practice is not an add-on. It is an integral part of the organisation. Designing with gender equality, disability and social inclusion in mind improves project quality and legitimacy.
For those asking how to help, the pathway is clear: join the partner network, watch for AWP calls, and bring core skills. That applies to engineers and planners, as well as to economists, communicators, and facilitators. As Ransom put it, Australia’s contribution to global water security begins with real people doing real work together.
“Follow your passion, learn your trade, and stay open to opportunities. There is a lot of work to do, and your skills are needed.”
