The current research aims at establishing the socio-economic pressure factors behind these practices and also assesses the effectiveness of measures into reducing the risky use of agrochemicals.

Among the farmers in Esanland, 96% of them applied agrochemicals in their farming activities without first following the best practices, and the reason was that 61% of them mentioned that they were compelled to use it due to market demands.
