(iii) when restrictions were imposed on pastor-al movements, grazing lands came to be continuously used and the quality of pastures declined.

(iii) They needed a permit for entry. The timing of their entry and departure was specified, and the number of days they could spend in the forest was limited.
(iv) Pastoralists could no longer remain in an area even if forage was available. The grass was succulent and the undergrowth in the forest was ample.
(v) They had to move because the forest department permits that had been issued to them, now ruined their lives. The permit specified the periods in which they could be legally within a forest. If they overstayed, they were liable to fines.

The last few decades have seen enormous rise in animal meat production and byproducts. Poultry, fisheries, piggery, cattle, sheep and goat farming have developed considerably. Through Operation Flood and the Silver Revolution, milk and egg production have registered a record increase.

To get the maximum benefit from a crop field, we should (i) maintain the soil fertility through judicious use of manure and fertilizers. (ii) practise crop rotation. (iii) employ mixed cropping and intercropping method of agriculture. (iv) keep the weeds and insect pest population under control.

Why are manures and fertilizers used in fields?
Manure and fertilizers ale added to the soil of crop field to increase the fertility of soil and productivity of crop. They overcome the deficiency of nutrients in the soil of the field.
