Two excellent graphics, comparing the cereal yields per hectare and percapita cereal production, shows that, despite Green Revolution, India has been, in most charitable terms, a laggard.
Even Bangladesh appears to have done far better than us in both counts - productivity and total production. Interestingly, the biggest productivity improvements in India have come in the last two decades and not during the green revolution decades of 60s to 80s. Does this mean that the Green Revolution era increases in agriculture production were mostly due to increase in acreage (due to more land being brought under cultivation and increase in irrigation - do figures bear it out?) than improved productivity?
