Abstract

Achieving SDGs by 2030 such as “No poverty, zero hunger, good health” is the main priority for policy planning in Bangladesh. Key challenges faced in achieving these goals is encountered in the agricultural sector. This research focused on farmers’ perception of salinity and their management strategies, and the implications for policy makers to sustain rice production in the coastal areas of Bangladesh. Household survey data was collected from randomly selected 108 rice farming families from two south-west south-east coastal sub-districts. Semi-structured and pre-tested questionnaire were used to collect data from the respondents. Majority of the respondents (89%) reported that salinity has increased over the last 20 years and they also believe that the current salinity level in their fields are high. In a 2nd field trip 36 farmers from the original sample had soil from their fields measured over two time periods. Farmers’ perceived salinity level was then compared with measured field salinity in their rice field. Farmers’ perception of soil salinity level in their rice field aligns closely with the measured salinity level in the majority of the cases. It was also observed that farmers’ understanding of salinity level is strongly associated with in-field crop condition and soil appearance. 45% of respondents said their main signals of salinity were from the appearance of the plant and 22% of farmers also observed the inflorescence becoming white and grain unfilled in rice crops. Results also suggests that early transplanting of rice seedlings during Boro season rice and use of salt tolerant rice varieties having high tolerance during booting stage along with improved irrigation facilities can substantially reduce rice yield loss from salinity effects.
