Standing above the Yangtze River, eastern China overlooking the Three Gorges Dam and witnessing the sheer scale of this great river sustaining millions of lives, one cannot help but pause and ask: What can a river not endure?
Rivers carry everything we give them: our water, our waste, our hopes of growth, and the consequences of our choices. Yet how long can they continue to bear these pressures?
Across the world, river basins are under growing pressure from climate change impacts, rapid urbanisation and increasing demands on water, land, and ecosystems. These pressures do not stop at borders. What happens upstream shapes lives and livelihoods downstream. This is particularly evident in the Hindu Kush Himalaya (HKH), where rivers connect high mountain headwaters with densely populated downstream plains. In this context, managing water through isolated projects or sectoral approaches is no longer sufficient.
Integrated Water Resource Management (IWRM) is a holistic framework for managing water, land, and related resources to maximise social and economic benefits while safeguarding environmental sustainability. Within a river basin context, IRBM operationalises these core principles, a more context specific approach that responds to the interconnected and dynamic nature of a basin system. This brings science, governance, community perspectives together to manage water holistically.
Aligning upstream and downstream interests, coordinating across sectors, and integrating environmental and social priorities, IRBM supports a more resilient and equitable water management approach. In a region facing increasing flood risk, climate uncertainty, and water scarcity, managing rivers through an integrated approach is not just optional; it is fundamental.
I have been working in water sector for over 15 years, but my two weeks as part of ICIMOD’s IRBM cohort in 2025 significantly reshaped my perspectives on development practices. I started to see rivers not merely as channels conveying water, but as living systems that connect people, ecosystems, and economies across mountains and borders.
As a flood modeller, my focus has always been on analysing water-level data and running models to anticipate flood risks – how high the water will rise, when flooding may occur, and how to minimise impacts. Until recently, I viewed rivers primarily as technical problems to solve. Now, I realise that a river cannot be understood by looking at just a single segment. The course consistently emphasised the need to see beyond numerical inputs – that behind every data point is a human story: a farmer whose field may flood, a family deciding whether to evacuate, or a community striving to rebuild.
This perspective led me to realise that flood modelling tools are not merely scientific outputs, but decision-support instruments. They inform us when and where early warning alerts are needed, guide planners in locating critical infrastructures – such as schools and hospitals and help communities anticipate and prepare for what lies ahead. Ultimately, science must lead to practical action on the ground, where it matters most. The Gender equality, disability and social inclusion (GEDSI) module prompted me to reflect on these critical dimensions, especially in understanding how access to water and the impacts of disasters disproportionately affect women, children, elderly people, persons with disabilities, and marginalised communities. These groups often remain underrepresented in decision-making processes. As these discussions unfolded, they underscored that inclusion is not a peripheral consideration, but a foundational principle of effective IRBM. The governance and water diplomacy module demonstrated that river basin management is shaped not only by hydrology, but also by institutions, legal frameworks, power dynamics, and trust. For downstream countries such as Bangladesh, rivers are integral to the national economy, yet they originate in upstream countries – China, India, and Nepal. This transboundary context necessitates sustained engagement with the upstream countries through dialogue, negotiation and confidence-building. The course further reinforced that effective river basin management relies as much on cooperative relationships and transparent communication as on physical infrastructure. This concept came to life during the exposure visit to China, where theoretical learning and field experience blended seamlessly.
The Chengdu science city planning area illustrates the IRBM concept. Water is not treated as an obstacle to urban growth, but as an opportunity to reimagine and integrate it as an asset. The Xinlong lake functions simultaneously as flood storage, a microclimate regulator, an ecological habitat, and a social space. Rather than a single intervention, it was the coherence and integration between land-use planning, environmental protection, monitoring systems and community access that was most striking.
The Three Gorges Dam is remarkable not only for its immense scale and engineering marvels, but also for the powerful human stories behind its construction. Stories of relocating communities, efforts to preserve cultural heritage, and the broader challenge to balance progress with human values stand at the forefront. This experience reinforced a key IRBM principle: sustainable outcomes require integrating social, environmental and economic dimensions, rather than prioritising one at the expense of others.
I shared this journey with fellow training attendees from across the HKH. Informal exchanges during travel, site visits and discussions often revealed shared challenges despite differing national contexts. These interactions reinforced my understanding that although rivers are divided by administrative boundaries, the communities connected to them face remarkably similar issues of floods, water security and environmental change.
By the end of the learning journey, IRBM no longer felt like a framework confined to policy documents or academic discourse. It had become a way of thinking that connects technical analysis with governance, modelling with inclusion, and infrastructure with ecosystems. The experience strengthened my conviction that integrated, adaptive and participatory approaches are essential for managing river basins under increasing climate uncertainty.
I began the training with the mindset of viewing river management as maps, data points and flood protection structures. I now understand that it is broader: it is about ensuring cities can grow without losing wetlands, that dam projects account for the needs of the communities they displace, and that scientists and decision-makers work closely together.
I returned to my work in Bangladesh as a water management professional with a more grounded perspective. I will continue working with data and models, but I now recognise the people and stories behind them.
