When Adaptation Follows Hazard, Not Vulnerability: Flood Loss and Damage in Assam

Assam, one of India’s most flood-prone states, has a vulnerability to climate change that is shaped by a complex socio-political context and increasing biophysical pressures. A range of policies and on-the-ground initiatives have been introduced to support climate change adaptation (CCA). However, understanding what works, where, and how remains critical for advancing effective and equitable adaptation. This study addresses this gap by examining Assam, a historically flood-prone state that experiences significant loss and damage each year.

Despite widespread exposure to floods, loss and damage across Assam is uneven. In several districts, high vulnerability rather than flood intensity drives severe economic and non-economic loss and damage. In some cases, districts with relatively low flood hazards experience high loss and damage due to social, economic, and institutional vulnerabilities. Differences in the type and quality of adaptation implementation further shape these outcomes.

To examine the role of adaptation in reducing and managing loss and damage, qualitative fieldwork was conducted in three districts representing different drivers of flood impacts. Majuli, a river island that experiences floods almost every year, records relatively low loss and damage. This is largely due to lower vulnerability and the presence of effective adaptation measures. Long-term structural interventions and community-led practices have enabled adaptation to move beyond coping towards more transformative pathways.

In contrast, Barpeta, a district exposed to high flood hazard, experiences high loss and damage due to high socio-economic vulnerability. Deep inequalities, uneven community distribution, limited adaptive capacity, and local political dynamics constrain effective adaptation. As a result, adaptation efforts in Barpeta have largely progressed only from coping to intermediate, incremental adaptation, despite decades of recurrent flooding.

The third case, Udalguri, is located farther from the Brahmaputra and is primarily affected by flooding from smaller tributaries. Although flood intensity is relatively low, the district experiences high loss and damage, particularly loss of human life. Flooding is a relatively recent phenomenon in this area, and communities are poorly prepared. High vulnerability, driven by inadequate adaptation strategies, persistent social inequality, and pronounced caste–class differentiation, has kept adaptation responses at the coping stage, with little progression towards incremental change.

Insights from expert interviews, key informant interviews, focus group discussions, and community interactions reveal that adaptation planning in Assam is largely guided by flood hazard levels rather than vulnerability. This hazard-focused approach results in unequal protection and leaves highly vulnerable communities exposed to severe loss and damage, not only economic but also high non-economic, which is not even documented.

Overall, the findings demonstrate that flood impacts cannot be understood through water levels alone. Vulnerability fundamentally shapes how floods are experienced and how damaging they become, particularly in relation to non-economic loss and damage. By foregrounding lived experiences and overlooked forms of loss, this study argues for a shift in adaptation planning beyond physical flood control. Policies must recognize vulnerability, systematically document non-economic losses, and support locally grounded, socially just adaptation pathways that protect people, not only infrastructure. This is especially critical in regions like Assam, where social vulnerability continues to turn even moderate floods into human tragedies.
