Water governance shapes how decisions about water are made and put into practice. Water governance establishes who has the authority to decide how water is used, whose interests are represented and how decision-makers are held accountable.
It extends beyond the institutions responsible for water. Choices about agriculture or urban development, for example, affect how much water is available and who can access it. Governance connects these decisions, helping societies balance competing demands while protecting the ecosystems they depend on.
Water governance sets the rules and responsibilities that guide water management. Management puts those arrangements into practice. The distinction is useful, although governance also includes overseeing implementation.
During a drought, for example, governance determines how competing demands should be balanced and who has the authority to decide. Management involves carrying out that decision, such as adjusting withdrawals and monitoring the water available.
Decisions about water affect public health and food production, while influencing where businesses can operate. They also determine how much water remains available for ecosystems and the biodiversity they sustain.
These interests are closely connected. Wetlands can reduce flood risks for communities, while maintaining wet conditions in peatlands helps protect their carbon stores. Water governance therefore matters for climate mitigation as well as adaptation. Climate measures themselves need to account for water: expanding forests, for example, can change the water available elsewhere in a landscape.
Governance helps societies assess these connections and negotiate competing demands. Who participates matters, because decisions can overlook communities with little influence. Where water crosses borders, water diplomacy can help countries negotiate shared interests and build the relationships needed to sustain cooperation.
Effective water governance requires clear responsibilities and institutions with the authority to act. Those institutions also need reliable funding and the expertise to put policies into practice.
Coordination is essential when decisions affecting water sit in different parts of government. Agricultural policy, for example, may increase water demand without accounting for limits identified by environmental authorities. Institutions need ways to resolve these differences.
People affected by decisions should have meaningful opportunities to influence them. Public information helps them understand the choices being made, while accountability provides ways to challenge decisions and address failures.
Governance arrangements also need to reflect their context. Speaking about water diplomacy, Martina Klimes, PhD, SIWI’s Thematic Lead and Senior Advisor, Climate, Water and Peace, observes: “There is no one blueprint that fits every country, every basin.”
Monitoring and learning help institutions adapt their approaches as conditions change.
In the Zambezi Basin, SIWI worked with the Zambezi Watercourse Commission, ZAMCOM, to strengthen recognition of how land management supports rainfed agriculture. This contributed to the Council of Ministers adopting a Statement of Intent on Rainfed Agriculture in April 2024. The example shows how understanding water in landscapes can inform regional policy. Read the issue brief.
Water pricing and pollution charges influence how water is used, but their effectiveness depends on the institutions implementing them. Through the InnWater project, SIWI and partners explored economic instruments alongside participatory governance across five European pilot sites. The work highlighted why pricing reforms must consider affordability and why pollution charges need effective monitoring and enforcement. Explore the lessons from InnWater.
Landscape restoration can change water availability for surrounding communities. SIWI’s Water-smart Forest and Landscape Restoration Tool helps planners assess these effects and involve the people concerned. It guides participants in identifying relevant stakeholders and improving institutional arrangements, making water considerations part of restoration decisions from the outset. Explore the restoration tool.
Water scarcity puts governance under pressure when demand exceeds the water available. Pollution can further reduce the amount suitable for use, while excessive groundwater withdrawals can deplete reserves.
Climate change adds uncertainty by altering water availability and changing flood and drought risks. Institutions must respond while planning investments intended to last for decades.
Decisions outside the water sector can compound these pressures. Expanding food production or energy development may increase demand without sufficient consideration of the effects elsewhere. Where countries depend on shared water, the consequences can cross borders.
Addressing these pressures requires difficult choices about how much water can be used and how it should be shared. Institutions need the resources and authority to implement those choices.
Water governance often focuses on rivers and groundwater. Yet water availability also depends on what happens across the landscape. Soil moisture sustains vegetation, while evaporation and the release of moisture from plants help connect land with rainfall.
“So governing the full hydrological cycle is governing both: the blue cycle, and also the land use that is managing the green water, I would say,” explains James Leten, Senior Programme Manager at SIWI.
Blue water refers to water in rivers and lakes, as well as groundwater. Green water is moisture held in soil that plants can use. Governing their connections means accounting for how land use affects water throughout the landscape.
“Water needs to be integrated into landscape restoration from the start, into agricultural considerations and into reforestation initiatives,” says Anna Tengberg, PhD, Senior Advisor at SIWI.
This requires water institutions to work more closely with those shaping land use, considering how decisions in one place affect water elsewhere. Explore SIWI’s brief, Governing the Full Hydrological Cycle to Strengthen Water Resilience.
SIWI works with partners to improve how decisions about water are made and put into practice. We connect research with policy discussions and support institutions through advice and capacity development. As an independent and impartial institute, we create opportunities for dialogue between people whose decisions affect water.
Through the Shared Waters Partnership, we facilitate dialogue and support cooperation over shared water. Our work on the full water cycle explores how land-use decisions can better account for water availability.
World Water Week provides a platform for exchanging experience and examining approaches to these challenges. Alongside our research and advisory work, it helps connect knowledge with the people who can use it in decisions.
