This dataset consists of face-to-face interviews conducted with 381 households located across 10 selected coastal locations of Bangladesh during September–October 2018 using a structured interview schedule. The interviews collected information on the coastal farmers’ farming systems and their personal, social, economic and psychological characteristics. Farmers’ perceptions of changes in temperature, rainfall, cyclones, floods, droughts, salinity, farm productivity, farm management and farming systems over the past decade (2009–2018) compared with the previous decade (1999–2008) are also included in this dataset.
