I have been trying to keep up with this for several years.
IN fact my partner and I have been collecting heirloom seeds for several years and started growing a bit of our own food..I suggest others do the same, even if you live in the city and only have a small plot I think we could help keep so many from starving when monsanto monster finally kills commercial cropping.
The situation in India is horrible.
The 'Green revolution' that was started usuing Western methods, seeds and equipment started in the late 70s iirc, these crops need more water, do not yeild as much as tradional Indian crops did, they drilled wells to irrigate these new crops, the ground water is dramatically dropping they used to be able to get water at about 4 or 5 feet below soil levels..now they are into 300 foot deep wells and having to drill further..the well drilling is not cheap either.
These are farmers who live on or below poverty level incomes(and that is if they are well off).
