Which of the two climate change adaptation strategies - adjusting or improving farming (defined as Stepping Up) versus reducing or exiting farming (defined as Stepping Out) - provides better developmen-tal outcomes for smallholder farmers? Are the drivers of these two strategies different? Do the outcomes and drivers vary according to farmland holding size? We investigated these unanswered questions, inspired primarily by a widespread but unverified suggestion that stepping out of farming can be a better option for smallholders. We utilised recent survey data from over eight hundred smallholder households located in climatic hazard-prone areas in Bangladesh. We applied a holistic Driver-Strategy-Outcome analytical framework and rigorous statistical methods, including index-based data aggregation, and Structural Equation Modelling with 'mediation' and 'moderation' analyses. Contrary to widespread spec-ulations, we found that Stepping Out had a large negative effect on smallholders' livelihood Outcomes; while Stepping Up had a moderate, but positive effect. The natural-environmental Drivers of Stepping Up and Stepping Out were similar; however, the psychological-institutional Drivers of each differed, with the same factor acting as a driver for one strategy whilst as a deterrent for the other. We found significant 'mediatory' effects of both the adaptation Strategies on Outcomes as well as significant 'moderation' effects of farmland holding size on the Drivers and Outcomes, with the positive effect of Stepping Up observed for smallholders owing lands of <2.5 acres only. We call for relevant policies and interventions to exercise caution in promoting smallholders' exit from agriculture, and to adopt appropriate mitigating measures to manage such a transition. Moreover, smallholder agricultural development initiatives should not discount even the 'smallest of smallholders' and support them through 'diverse and complementary innovations' as well as 'tailored' institutional support services, especially for those living in proximity to hazard hotspots.
