Research Objective

To explore the effects of excessive use of agrochemicals on farming practices in Bangladesh.

Methodology

A structured questionnaire and face-to-face interviews were conducted with 150 randomly selected farmers in Satkhira sadar upazila, Satkhira district, Bangladesh. Focus Group Discussions (FGDs) and Key Informant Interviews (KIIs) were also performed. The perceived effect of excessive agrochemical use was the focus variable, with socio-economic attributes as explanatory variables. Data were analyzed using descriptive statistics and correlation analysis with SPSS version 27. A 4-point rating scale and Perception Effect Index (PEI) were used to assess the effects.

Discussion

The study highlights a dual perception among farmers regarding agrochemicals: immediate benefits like increased yield versus long-term negative consequences on health and the environment. Despite awareness of negative impacts, factors like the pursuit of higher yields, lack of training, and limited access to extension services drive excessive use. The positive correlation between socio-economic attributes (education, experience, training, knowledge, awareness) and perceived effects suggests that improving these factors could lead to more balanced agrochemical use. The findings underscore the need for integrated strategies that combine training, awareness campaigns, and sustainable farming systems.

Key Findings

- A majority of respondents (48.7%) perceived high positive effects of excessive agrochemical use, while 59.3% perceived medium negative effects.
- The most positive perceived effect was increased productivity and cropping intensity (91.8%), while the worst perceived effect was being poisonous to humans, animals, and soil microorganisms (82.7%).
- The primary cause for overuse was the provision of higher yield (94.7%).
- Agricultural training was suggested as the best management practice (95.3%).
- Perceived effects of agrochemical usage were positively correlated with educational qualification, farming experience, agricultural training, extension media contact, knowledge, and awareness.

Conclusion

Excessive use of agrochemicals in Bangladesh is driven by the pursuit of higher yields, compounded by farmers' limited education, training, and awareness. While perceived positive effects on productivity are significant, the negative impacts on human health and the environment are also recognized. Enhancing farmers' knowledge, awareness, and access to extension services, alongside promoting sustainable farming practices, is crucial for mitigating the adverse effects of agrochemical overuse and protecting future generations.
