financial assistance to farmers through government-sponsored price-support programs.
Energy efficiency ratio
A measure of the amount of energy inputs into a system compared with the outputs. EER = energy outputs divided by energy inputs. Used to compute sustainablility in agriculture. Inputs should be smaller than outputs.
an amount of a renewable recourse that can be harvested regularly with out reducing the future supply.
Diseases of affluence

The spread of something
A disease spreads from a source location outwards
