The concept of Food Security has evolved during the last 3 decades to include not only
food availability, but also economic access to food and the biological absorption of food
in the body. Adequate per capita availability of food is a function of the balance between
food production on the one hand, and growth in population and purchasing power, on the
other. Urbanisation enhances the consumption of animal products and thereby increases
the demand for feed grains and fodder. The “green revolution” of the sixties and
seventies helped developing countries to gain a breathing spell during which they could
attempt to achieve a balance between population growth and the population supporting
capacity of the ecosystems. Inspite of the success of the population stabilising efforts in
many developing countries, the UN projections indicate that the global population may
range from 8 to 10 billion by 2050. I would like to discuss in this paper the challenge of
achieving sustainable advances in farm productivity, leading to an “ever-green
revolution” in the fields of farm families with small holdings.
