Discriminated perceptions of climatic impacts on coastal farm management practices

Agriculture is responsive to weather and climate variability. In addition to the climatic stressors, coastal agriculture is influenced by non-climatic factors. Therefore, understanding farmers' perception of the causes of their changes in farm management plays a key role in motivating them to adopt agricultural adaptations. The aim of this study was to investigate the changes in coastal farm management in Bangladesh over the last decade compared to the previous one. We explored whether the causes of those changes were climatic or non-climatic as perceived by the farmers and the factors that shaped their perceptions. We interviewed 381 farmers sampled from ten subdistricts along the coast of Bangladesh. Descriptive statistics showed that the farmers had changed on average 10 to 11 farm management practices. Though the average value was 67%, a higher number of farmers in the western coastal zone mentioned that climate change had impacts on their farm management. Adoption of rice crop-related adaptations was greater than livestock, fisheries or general agricultural practices. According to the discriminant function analysis, discriminative variables were perception of climatic impacts on farm productivity, climate change awareness, involvement with non-farm jobs, age, education, organizational affiliation, number of changed farm practices, and meteorologically consistent perception of rainfall and temperature. Lessons learned from this research are that the farmers should better understand the link between climate change and farm management practices while motivating them to implement adaptation strategies. This could be achieved by improving farmers' climate change awareness, perceptions of changes in climatic parameters and involvement with farm-related associations.
