Portfolio diversification

I look at my current portfolio, do some analysis and think these are the few diversification I will make over the next few months ( or the year maybe) -

1. I have a decent exposure to debt - but that is primarily in the form of my provident fund which earns me 8% ( think that's what it is now). No short term debt ( have some , but a convoluted Overdraft on that is what is my working capital for a lot of expense I am incurring now). so should I increase my debt portion? not sure I want to do it. I will need some cash as backup and they will primarily go to create a OD with some debt backing them
2. Commodities - this will be the next big thing in India ( it already is) - but I don't trade commodities. ( here my attraction is in the agri related commodities and not ferrous/ non ferrous metals). Agriculture has lagged in our economy for far too long. Given the fact that 60% of the population is dependent on it and we need to secure our food security, I expect movement on this area , more out of force than genuine concern. Its a 2-3 year play and should be very rewarding. I am still not sure how to play this, but will keep you posted
3. Gold - I think this is an asset class I will need some exposure to. I can do it either thru physical gold, Gold ETFs and through a hybrid fund like DSPML which invests across the gold value chain. I am not sure if physical makes sense, but will evaluate the other two.
   
4. Commercial real estate - I think this will create a cash flow scenario. Also , when I say commercial real estate, its basically a small office/ shop version - This will need me to put down some capital and leverage hard. I am hoping the real estate will fall further to allow me to pick some up. This will need lots of cash, I might just have to team up with a few friends ( assuming they are willing). Here once the REITS come in, I should be able to build an exposure, but I think that is atleast 13 -15 months away in India.
   
5. Some other slightly weirder ideas - like financing a moveable asset like a mini truck, or some small microfinance institution, or something.
   

Keep in mind that I don't have huge sums - I am assuming here, I will find like minded people and find the right opportunities. I want to take slightly larger risks, diversify the cash flows and see if I have to guts to take the opportunity given by the Indian economy to the build capital for myself.
