The Real Test of Water Governance Lies at the Basin Level
World Water Week in Stockholm has long been a place where the water community takes stock of its priorities. This year, however, a more fundamental question ran through many discussions: is the way we govern water still adequate for the world we are entering?
Over recent decades, water governance has become increasingly institutionalised, from basin organisations and national water laws to global agreements and partnerships.
Yet World Water Week 2026 underlined the growing mismatch between this institutional architecture, and the nature of the water challenge itself.
From water crisis to governance crisis
Discussions during the week, fronted particularly by this year’s Stockholm Water Prize winner, Professor Kaveh Madani’s framing of water bankruptcy reinforced a simple reality: many societies are using water beyond sustainable limits.
That is fundamentally a governance problem.
Infrastructure, technology and nature-based solutions can improve supply, efficiency and resilience. But they do not determine who should receive increasingly scarce water, which uses should be constrained, how environmental flows should be protected, or how agricultural and energy policies should change when demand exceeds supply.
Those are political choices.
At what level does water governance work?
The hydrological basin remains the natural unit for understanding water systems, but many of the decisions that determine water outcomes are taken elsewhere. Agricultural policy may be determined nationally, investment in infrastructure determined by the Ministry of Finance, and land-use decisions made locally. Who decides, who understands, and what really is happening with water?
The focus in Stockholm on ‘green water’ also reinforced a broader point on governing the whole hydrological cycle. Water governance should no longer focus only on the water we can see, measure, store, abstract and allocate. Water availability is also shaped by soils, vegetation, wetlands, forests, infiltration and evapotranspiration. Governing the full hydrological cycle will require influencing decisions well beyond the institutions traditionally responsible for water.
Effective governance therefore depends less on identifying the "correct" geographical scale, but more on ensuring that decisions taken at different scales are aligned. The basin provides the hydrological logic, national governments much of the authority and finance, and local institutions the legitimacy and implementation capacity. Recognising of course that groundwater does not 'fit' within the basin as a 'unit'.
What is global water governance for?
We need to be clearer about the purpose of global water governance.
Global water governance should provide a shared vision for managing the water cycle while creating the conditions for better decision-making nationally, across borders and within basins. Doing so requires greater coherence across the international frameworks that shape water outcomes, particularly those addressing climate, biodiversity and land degradation. The opportunity is not simply better coordination, but the mobilisation of solutions that strengthen water security.
Global water governance should ultimately be judged by whether it enables better decisions where water challenges become tangible: at the basin level.
One response to this challenge is proposed in IUCN’s Global Framework for Water Governance and Action. IUCN argues that while important legal, policy and institutional instruments already exist, the global architecture remains too fragmented to sustain political attention, strengthen implementation, align finance and support accountability.
The proposition is therefore not another large global water institution. It is a more durable architecture connecting what already exists.
But, governance is not coordination alone. It is authority, incentives and accountability. Among the most powerful of these incentives are financial ones.
This means moving beyond the familiar financing-gap discussion.
Finance ministries, development banks, investors and sectoral economic policy need to be engaged. Finance needs to be aligned with hydrological and ecological realities rather than simply increasing the volume of finance labelled for water. This isn't about just mobilising more finance for big projects; it is about changing the policies that determine what are the right investments for a secure water future.
The opportunity for Abu Dhabi
Stockholm reinforced that water is now recognised as a systemic challenge. The next step is to ensure that water governance reflects that reality.
The 2026 UN Water Conference offers an opportunity to start building a more durable architecture to help governments make better choices about water.
The measure of success is simple: are decisions changing, and are water systems, ecosystems and communities becoming more resilient where those decisions matter most, at the basin level?
