Sufficiency is obviously related to sustainability. It is also inherently related to the eco-friendly concept. Sufficiency is a philosophy and a state of mind. To know when is “enough” or “Sufficiency” in all aspects of life is quite abstract and Sufficiency to pin-point. It is specific and different to each and every person. It may well start with an accounting of the expenses and revenue of the household. Good accounting gives a clear picture of how much is enough to survive comfortably, as well as what is not necessary. Changing the way of life and agricultural practice to suit the nature and environment will help to reduce what is not needed, such as planting a good combination of fruits, vegetables, and herbs to be used as bio-insecticide, and raising animals as a source of food and labour in the farms or paddy fields, with manure to be used as organic fertiliser or to generate electricity.
