How does one measure poverty

Interesting that it took so long to finally junk calorie intake as the poverty estimation tool. Even if one take mere food as an indicator I wonder if the calorie intake took into account nutritional needs like proportion of protein/carbs/minerals/vitamins etc.
I think putting things like Education, access to health-care in ambit of calculating poverty is a step in right direction. After all these define your quality of life and also define in a rudimentary way the opportunities available to better the quality of life. Lack of opportunity is what will keep the poor poor and as such is as much a handicap as lack of food/shelter etc.
Its kind of sobering to think by that yardstick India is still miserably poor. I suggest we also put in place a mechanism to evaluation the effectiveness of poverty removal programs. Accordingly government agencies (and private/NGOs) can also be rated as 'good to reduce poverty, not so good etc'. Organizations that serve to reduce total poverty can be given additional incentives. Otherwise I wonder if any real poverty alleviation will happen in near future.
