Dear SANetters,

I am trying to work out the sustainable food production capacity of a small
state called Kerala in the southern most tip of India.

The amount of food grains that can be produced in the state is
limited. But there is ample scope for production of fruits, some of the
tropical vegetables and a lot of Tubers (like yams, colocassia, cassava..).
It is also possible to obtain a lot of sea-food. Fruits mentioned above
include large quantities of mango, banana (different varieties of
plantains), a lot of jack-fruit etc.... It is also possible to produce
large quantities of greens.

My question is- can any of the above food replace grains?
(Here grain practically means rice- the staple diet of people in the state).
A lot of coconut pulp is also consumed as the part of food- almost to the
tune of 200 gms/family/day (family of five people). Can this cocnut pulp
substitute a part of the grain consumption?

I would be greatful if anybody can enlighten me about this.

Thanks in advance

Yours sincerely
