Dear Bhuwan Adhikari and Qimiao Fan ,
1) I agree that decentralization is one of the possible solution to improve life of people in Dhaka.
2) If conventional method of improving infrastructure the all will be go in hands of "Elite" per so many past expereince.
3) Even money for decentralization efforts may go under "Elite Capture" per past history.
4) I suggest that link it with rural development and hand over cluster to each rural unit and wonder will come .
5) Await your out of box input in this respect .
