Purpose: Facilitation of learning enhances innovation through overcoming innovation barriers and supporting learning outcomes. However, little is known about how public Extension and Advisory Services (EAS) facilitate learning to help adapt to particular climate stressors. This article investigates the role of public EAS in facilitating learning to enhance innovation in a flash flood-affected farming context. Design/methodology/approach: The research adopted flash flood-affected rice farming in Bangladesh as a case and collected data with actors involved in various extension approaches using interviews and focus group discussions. Findings: Public EAS should involve a range of relevant actors, including the private sector and scientists, and jointly evaluate with farmers and provide feedback on the effectiveness of various crop cultivation strategies for flash flood adaptation. Public EAS needs to deliver the necessary instrumental support and resources to achieve learning outcomes and enable farmers to make desirable changes to farm activities. Practical implications: Policy makers need to develop policies for the capacity development of public EAS staff and provide adequate resources so that public EAS can facilitate learning approaches to support discussions on local concerns and the use of local knowledge, experiences, and resources for flash flood adaptation. Theoretical implications: Facilitation of learning to support adoption of technological innovations is not sufficient in the context of flash flood adaptation. Facilitation should support discussions on effective utilisation of natural and common resources for the flash flooding context. Originality/value: The study investigated the ways public EAS can facilitate learning to overcome barriers to innovation and support learning outcomes in a flash flooding context.
