ABSTRACT
Modern economists emphasise the catalytic role that technological changes play in the growth of an economy. These changes bring about an increase in per capita income, either by reducing the amount of inputs per unit of output or by yielding more output for a given amount of input (Mathur 1953). Technological change of an economy, therefore, refers to changes in the input-output relations of production activities. Consequently, as an economy moves from lower to higher stages of development, there occurs a shift from simpler to more modern and complicated techniques of production on the one hand and ecological fallouts on the other (Leontief 1963). International evidence is indicative of the fact that agriculture revolution has generated the much-needed food security and at the same time has raised alarming signs for the ecology as well.
