New frontiers in water policy and water rights

A changing climate and rising tensions over shared rivers are pushing water to the centre of development policy. This article explores new frontiers in water policy and water rights, from systems thinking and equity to blue/green water and transboundary governance.

New frontiers in water policy and water rights

My recent evaluations in the water and WASH sectors have reminded me how quickly this field is evolving. The traditional concerns of coverage, service quality and cost recovery are still central, but new frontiers in water policy and water rights are now shaping development debates in ways that go well beyond pipes and pumps. This article explores new frontiers in water policy and water rights, from systems thinking and equity to blue/green water and transboundary governance, and what this means for development policy and practice.

New frontiers in water policy

When I think about new frontiers in water policy, the first shift I see is from projects to systems. Over the past decade, the sector has moved decisively away from counting taps and toilets towards understanding how institutions, finance, data and accountability interact over time. Systems‑focused organisations have helped popularise tools such as district WASH master plans, systems‑strength assessments and life‑cycle costing.

At the same time, global initiatives are embracing “water writ large” approaches that connect water resources management, service delivery and climate resilience. This has pushed water policy out of the narrow domain of line ministries and into cross‑government conversations involving finance, planning, environment and agriculture. For my own work on integrated policy design, this means that water can no longer be treated as a self‑contained sector.

Equity, inclusion and political stability

Another frontier in water policy involves equity and inclusion, and their links to political stability. The human right to water and sanitation is widely recognised, and most national strategies make strong commitments to “leave no one behind.” Yet the reality in many countries is that rural communities, informal settlements, displaced people and marginalised groups still face the greatest barriers to safe water and sanitation.

In my recent assignments, I have seen how programmes that explicitly focus on gender equity and social inclusion can start to shift this picture. They do so by embedding inclusion into monitoring frameworks, financing decisions and service models, rather than treating it as an add‑on. The interesting insight for me is that equitable water services are not just about fairness; they can also strengthen the social contract between citizens and the state, reducing grievance in contexts where water scarcity and climate impacts are politically sensitive.

Water rights, sovereignty and shared rivers

The most politically visible frontier is around water rights, sovereignty and shared rivers. The Grand Ethiopian Renaissance Dam on the Blue Nile is one of the best‑known examples, but it's far from unique. Upstream and downstream states across the world are wrestling with questions of “equitable and reasonable use,” historical treaties and changing hydrology.

These disputes raise fundamental questions about where a country’s water really comes from. Rainfall patterns are shaped by regional climate systems. Rivers cross multiple borders. Groundwater aquifers often extend under several countries. Yet domestic debates about water rights tend to frame water as a national asset, fully under sovereign control.

This is where the distinction between “blue water” (surface and groundwater) and “green water” (soil moisture and evapotranspiration) becomes analytically useful. Much of the water that supports food production and ecosystems never appears in traditional river‑sharing agreements. As climate change alters both blue and green water regimes, we are likely to see more disputes, but also more opportunities for cooperation through shared investment in resilience.

Blue water, green water and nature‑based trade‑offs

The concept of blue and green water also affects policy and practice at national and local levels. Conventional water policy tends to prioritise blue water—dams, canals and groundwater abstraction. Climate‑resilient development, by contrast, requires much more attention to green water through soil conservation, watershed management and landscape restoration.

In my work, I have seen growing interest in nature‑based solutions that combine water, land and ecosystem objectives: rehabilitating wetlands, promoting agroforestry, restoring degraded catchments. These interventions can reduce flood risk, improve water quality and support livelihoods, but they also blur the lines between sectors and budgets. They force ministries and agencies to collaborate in ways that do not fit traditional silos.

For practitioners, these ideas open up new questions for development policy and practice: How do we weigh short‑term production gains against long‑term ecosystem health? How do we design institutions that can manage both blue and green water under conditions of uncertainty? And how do we bring communities and local governments into decisions that used to be made exclusively by engineers and economists?

Water as a strategic political issue

When I step back from these different strands—systems thinking, equity, transboundary rights, blue and green water—I see a common thread. Water is becoming an increasingly strategic political issue. It cuts across borders, sectors and interests, and it forces explicit choices about who gains, who pays and who bears risk.

For those of us working in evaluation, policy and private sector development, this creates both challenges and opportunities. The challenge is to move beyond technical comfort zones and engage with power, rights and long‑term trade‑offs. The opportunity is to help design and test new forms of cooperation: local platforms that build inclusive water systems, national reforms that align water and growth strategies, and regional agreements that balance sovereignty with shared resilience.
