How can we grow enough food

without polluting our environment?

• Green revolution in India has witnessed a jump in agricultural production with the introduction of high yielding varieties of various crops and by following intensive cultivation practices with the use of fertilizers, pesticides and other inputs.

• The intensive use of fertilizers and pesticides have not only polluted the soil, water and the environment causing their slow degradation but also affected the human beings.

• Therefore, there is a need to study the effect of fertilizers and pesticides on soil fertility and design strategies for sustainable agriculture.

Out of 6 students in your group, two of you will assume one of the following roles –

• Agriculture Officer

• Entomologist

• Social Worker

Areas of Work• Agricultural officer – Analyses various methods of

cultivation for better yield and studies the impact of chemical / organic / both fertilizers on crop yield.

• Entomologist – Studies the problems faced by farmers by pests and the effect of pesticides for better yield.

• Social worker – Identifies and analyses the socio-economic problems facing by the farmers. Studies the impact of using chemical / organic / both fertilizers on their life
