1) How much should the tax be so as to encourage the farmer to reduce his TFI by 30% per hectare (test a 10% tax, then 30%, 50% and 70%) ?
\nThe tax must at least be of 50% so as to encourage the farmer to reduce his TIF by 30% per hectare.<\/p>\n

2) Does the tax increase have an impact on cropping patterns ?<\/p>\n

The tax increase has an impact on cropping patterns and their income. The higher the tax, the lower the income. And more money thus enters State funds.<\/p>\n

3) Is it possible to encourage the farmer to switch to Integrated Pest Management at cropping system level <\/em>(systCI) with this policy ? Explain.<\/p>\n

To encourage the farmer to switch to Integrated Pest Management at cropping system level, a 200% loan tax would be necessary.<\/p>\n

4) Compare the acceptability of this tax with that of subsidies.<\/p>\n

Subsidies costs the State whereas taxation allows the State to make money. As for the farmer, his income becomes more significant with subsidies. An average TIF of 2\/ha requires a 200% tax. The acceptability of such a significant tax can be questioned, while the subsidy has been approved.<\/p>\n
