Is there a single most important factor that is causing price instability for food grains experienced globally since the year 2007? The straight answer is the distorted demand-supply situation with supply lagging behind due to many reasons. Agricultural scientists have done a yeoman service in the past in developing better seed materials and improved cultivation practices which benefited millions of farmers all over the world. Now that there are uncertainties regarding the ability of mankind to double the food production before the end of this century to feed a population of about 10 billion, what lies ahead for humanity in a world with grossly inadequate food supply?
Man's thoughtless past practices have depleted the fossil fuel source, reduced water availability due to overuse, fouled the environment due to heat generating CO2, affected adversely the health of millions because of reckless use of pesticides and destroyed soil health by indiscriminate application of chemical fertilizers. There is no unanimity regarding the exact cause for near stagnation in food production, post-green revolution period but majority agree that abrupt weather changes, unusually high temperature conditions, frequent droughts and flooding have all contributed to this unhappy situation.
