Recent advances on power, politics, and pathways in climate change adaptation aim to re-frame decision-making processes from development-as-usual to openings for transformational adaptation. This paper offers empirical insights regarding decision-making politics in the context of collective learning through participatory scenario building and flexible flood management and planning in the Eastern Brahmaputra Basin of Assam, India. By foregrounding intergroup and intragroup power dynamics in such collective learning spaces and how they intersect with existing micropolitics of adaptation on the ground, we examine opportunities for and limitations to challenging entrenched authority and subjectivities. Our results suggest that emancipatory agency can indeed emerge but is likely to be fluid and multifaceted. Community actors who are best positioned to resist higher-level domination may well be imbricated in oppression at home. While participatory co-learning as embraced here might open some spaces for transformation, others close down or remain shut. [ABSTRACT FROM AUTHOR]

The randomness in morphology of the Brahmaputra River is very common because of its high flow variability and erodible banks. The river is severely braided with no permanent bank line and varies its width by 1.2 km to 18 km. During the monsoon season it follows several tortuous braided paths to dissipate its enormous energy. The river changes its braided planform in response to seasonal water and sediment waves and makes its morphology extremely complex. This paper aims to link the braided planform disorderness as a measure of entropy with the energy dissipated by the braided river system to study the river behaviour for various flood waves.
