It's a long time Bangladesh becoming a city-based country. Many researchers have examined it in many ways. Capital city Dhaka has fulfilled it's 400 years existence. Between this time there are many changes we saw. Researchers' main objective was to find out the progress and pores-cones. As the Dhaka has expanded varieties of the problem has increased.
The main problem is multi-storeyed buildings and apartments. These unplanned and structureless buildings the city has always been at risk. On the other way, a lot of slams build in everywhere.
Last year Dhaka city was listed by an inhabited city. According to researchers Dhaka city rapidly moving towards urbanization, so many unexpected accidents happened.
Than ever before auto-rickshaws, roadside markets, shops, hotels, restaurants, schools, and colleges have grown abnormally. All of this building without any plans.
Now our activism and efforts can make the city-friendly.
