Farmers' Perception towards Sand Deposition Effects on Agriculture in Jamuna River Floodplain, Bangladesh

Abstract

Seasonal flooding often leads to sand accumulation on farmlands, which affects soil fertility, reduces crop yields, and disrupts farming activities. This study explores farmers’ perceptions towards the impact of sand deposition on agricultural land and livelihoods along the Jamuna River floodplain in Kazipur Upazila, Bangladesh. Data were collected from 80 farmers in two unions through face to face interviews using a semi-structured questionnaire. Findings revealed that respondent farmers showed marked individual differences in their socio-economic status. Most farmers believe sand deposition significantly reduces agricultural productivity (agreed by 90% of respondents), causes the loss of arable land (91.3%), degrades soil (90%), and leads to economic losses (88.8%). These high agreement levels reflect strong concern about the negative impacts of sand deposition. Statistical analysis revealed significant positive relationships between farmers’ perceptions and factors such as agricultural income (r = 0.322, p < 0.01), distance from the riverbank (r = 0.427, p < 0.01), and the extent of land affected by sand deposition (r = 0.308, p < 0.01). The findings highlight the urgent need for sustainable land management strategies and targeted support to protect agricultural livelihoods in vulnerable riverine areas.
