This article provides a comprehensive institutional analysis to better understand the key conditions and incentives relevant for the uptake of alternate wetting and drying (AWD) – a climate-smart irrigation practice in Bangladesh. Practicing AWD in rice production can reduce water consumption by 30% and mitigate methane emissions by 30–70% without yield penalty. Primary research was conducted in Rangpur, Rajshahi, Mymensingh, and Sherpur Divisions. The analysis depicts the dynamic among the stakeholders involved in scaling AWD using the Net-Map tool, and demonstrates the influence of irrigation management systems in the selected catchment areas and the impacts of AWD in rice farming. Findings reveal that AWD-practicing farmers, pump owners, and the Upazila Irrigation Committee are the three most powerful influencers for scaling AWD. The pre-paid irrigation system significantly improves water efficiency and cost-effectiveness when practising AWD. Additionally, AWD leads to a lower frequency of pumping resulting in reduced costs compared to the continuous-flooding practice. Finally, the results guide the formulation of recommendations to create favourable conditions for AWD scaling, which contributes to reducing greenhouse gas emissions and advancing sustainable rice production in Bangladesh.
