Home-grown feed crops, such as peas, beans and lupins, need to be encouraged.

That way, land currently used to grow feed crops like corn and hay could be used for more sustainable purposes, such as planting trees.

But because the feed crops are grown with heavy inputs of chemical fertiliser, pesticides and diesel fuel, they can hardly be considered 'climate-friendly'.

All types of pulses, jowar, maize, bajra, cotton, etc., are the rain fed crops.

Because of this cattle industry, local farmers grew more corn, alfalfa, and other feed crops during the 1900s and 1910s.
