Due to both natural and anthropogenic forces, the south west part of the Ganges-Brahmaputra coastal area is facing diverse problems such as waterlogging, salinity, and loss of biodiversity. In order to address these challenges, local people have identified 'tidal river management (TRM)' as a comprehensive approach for sustainably managing this part of the GangesBrahmaputra Basin. However, due to institutional limitations, mismanagement and social conflicts, application of the TRM approach is not straightforward. In order to identify existing implementation barriers and to effectively apply the TRM approach, a transdisciplinary approach is examined for its potential to inform the re-shaping of TRM governing values and actions. It is argued that a thorough application of a transdisciplinary framework is essential, supported by the active involvement of key agencies and local stakeholders. The proposed transdisciplinary framework can potentially be applied to TRM projects for solving waterlogging and associated problems in order to achieve greater sustainability of the area.

Internationally, a wide set of measures are being considered to reduce flood risk: natural flood management (NFM) is one of them. NFM includes a broad range of measures that alter, restore or use landscape features to manage flood risk. By working with catchment‐wide hydrological and morphological processes, NFM aims to manage the sources and pathways of floodwaters. NFM can nevertheless conflict with other land uses, in particular agricultural food production. Our research aimed to explore farmers' perceptions of NFM and identify the criteria influencing decision making in implementation. Using findings from a workshop, qualitative interviews and a national survey carried out in Scotland, this paper identifies six key criteria that farmers consider when implementing NFM: economics, availability of advice and support, public perception, joined‐up policy, catchment planning and traditions. While a number of these criteria are consistent with the agri‐environment literature and other flood management studies, our study makes some novel findings regarding farmer perceptions and how NFM affects the farm business. We conclude that NFM installation could be encouraged through one‐to‐one advice from a trusted facilitator and long‐term financial incentives that compliment other farm payments. This should be combined with a catchment approach to flooding, which highlights shared responsibility for reducing flood risk.

Integrated Water Resources Management (IWRM) is now a global paradigm. While conceptions of IWRM principles vary between contexts, it primarily aims to ensure more coordinated management between different aspects of water issues such as water quality, land management and habitat protection. However, one increasingly significant cross-cutting management issue is climate change adaptation which presents multiple problems for IWRM approaches. This paper therefore seeks to gauge the extent to which IWRM principles can, and indeed are, enhancing the adaptive capacity of water management through reducing vulnerability and increasing the resilience of social-ecological systems. A review of research into vulnerability and resilience to date suggests that IWRM has significant potential for supporting some of the key determinants of adaptive capacity. However, despite IWRM being promoted as an attractive approach, our assessment argues that IWRM, as currently practiced, cannot readily enhance flexibility and adaptability, which is required for climate change adaptation. Normative recommendations for future policy are then provided.

Optimizing the capacity to adapt to climate change impacts has become a critical challenge for human societies. This article therefore evaluates how integrated water resource management (IWRM) approaches help enhance adaptive capacity to climate change impacts on water resources. An evaluative framework is derived from key IWRM principles and their roles in modulating adaptive capacity. This framework is then used to evaluate IWRM implementation in Bangladesh. The analysis draws on policy documents, interviews and a survey of policy makers. Results suggest that policy principles and implementation in favour of IWRM can be a source of success but also of failure for adaptive capacity. Recommendations for amending the concept with the aim of increasing adaptive capacity are outlined.
