Climate change and farm-level adaptation decisions and strategies in drought-prone and groundwater-depleted areas of Bangladesh: an empirical investigation

- Breaks new ground on climate change adaptation by Bangladeshi rice farmers
- First comprehensive quantitative study on farm-level adaptation for Bangladesh
- Identifies key socio-economic and climate factors underlying adaptation strategies
- Discusses policy implications for an enabling environment for adaptation
- Supports science-based adaptation strategies backed strong support system

Despite recognizing the vulnerability of Bangladesh's agriculture to climate change, the existing literature pays limited attention to a rigorous, quantitative analysis of farm-level data to investigate rice farmers' preferred adaptation strategies, perceived barriers, and policy implications. By employing data from 1800 Bangladeshi farm-households in eight drought-prone and groundwater-depleted districts of three climatic zones and logit models, this study breaks new ground in investigating farm-level adaptation to climate change.Results showed that farmers' perceptions of climatic variability supported macro-level evidence. Science-driven (e.g., drought tolerant rice), environmental resource-depleting (e.g., groundwater), and crop-switching (e.g., non-rice crops) typified preferred farm-level adaptation strategies to alleviate adverse effects of climate change. Drought severity, extent of groundwater depletion, education level, farm-size, access to climate information, and electricity for irrigation, and agricultural subsidies were significant factors underpinning farmers' decision to adapt. Inadequate access to climate information and scientific research outcomes, limited irrigation facility and resource-base represented major adaptation barriers.Strengthening agricultural research and support services including information accessibility, community-focussed farming education and training for improved crop culture practices, and expanded and efficient surface-water irrigation infrastructure are critically important for creating an effective adaptation process to climate change. Scientific research-driven adaptation measures with stronger support systems appear more sustainable.
