Hi Cj, Thank you for your comment! 
The idea is to grow the market so that farmers will grow. Why should we focus on this at all, you might ask:
1. These grains as you correctly understood are very nutritious and cheap (in fact a lot of farming families continue to grow these millets and cereals for personal consumption) and will help combat hunger.
2. These crops are naturally suited to soil and weather conditions and also their growing cycles help in rejuvenating soil quality naturally without any need for fertilisers or chemicals.
3. They form an important part of the food culture and traditions in India and we'd like to preserve them :) All you guys Basmati is NOT the only Indian rice variety, you will be amazed how many different varieties of rice we grow. 
Take a look at this: http://www.livemint.com/Leisure/bmr5i8vBw06RDiNFms2swK/Debal-Deb--The-barefoot-conservator.html
Now the question is how do we do that? How do we encourage consumers to buy these products?
1. Through cooking programs
2. Recipes that could be used on packaging
3. Linking up tourism by encouraging companies to work with these communities for home stays where people can watch how the food is grown and also get to experiment with how to prepare them

I have tried to link up this idea with a whole systems approach where one can build an entire new sustainable business eco system around producing these grains.  
I am exploring as well and thank you for your thoughts. Do let me know if you have any comments/ideas.

Thanks! I can't think of a visual but here is a brief look at community-based savings: http://www.akdn.org/publications/2012_india_cbsg.pdf
Perhaps this could help?
