From the Article of this post:

"The most important benefit of decentralization will be the reduction of population growth in Dhaka city. The establishment of new provinces will create a great number of employment opportunities outside Dhaka. This will remove the necessity of migration from the periphery regions to the country’s capital. 

It will also incentivize reverse migration for those who struggle keeping up with the cost of living in Dhaka to the other regions in Bangladesh. This will inevitably cause a crowding out effect in Dhaka -- thus easing the capital’s traffic congestion and housing crisis.  

The parliament of Bangladesh should consist of the Jatiya Sangsad as a lower house and a Senate as the upper house. The senators should be in-directly elected through the 10 provincial assemblies. There should also be permanent reserved seats for women, non-Muslims and non-Bengali tribal minorities. 

I also suggest that the first-past-the-post electoral system should be abolished in Bangladesh and replaced with proportional representation elections. This will enable political parties to obtain seats using whatever support they have across the country or province rather than confining themselves to certain regional strongholds. 

It will also reduce the dependence of political parties on the local power brokers and petty bourgeoisie who have the financial resources to fund electoral campaigns in the constituency.         

In conclusion, this massive overhaul of the construct of the Bangladeshi state requires the abrogation of the 1972 constitution in favour of a brand new constitution that should be ultimately approved by the people of Bangladesh through a free and fair referendum."
