Here is the often-cited classic on the agricultural practices followed in India and why organic farming methods are sustainable means of producing food.
Such a classic!
It is important here to clarify that sustainable means of food production must encompass an integrated approach that includes organic farming methods (i.e., without using synthetic pesticides and fertilisers), use of open pollinated seeds, multi-cropping, and soil rejuvenation practices. Sustainable approaches also promote local production & consumption. Today ‘organic farming’ is used only for what is termed ‘chemical free’ food production. Monoculture of food crops aimed primarily for the export market or for external urban markets is done using organic methods. As a result water, soil and other resources from rural areas are ‘exported’ rather than nourishing local communities.
