No plan to improve the living standard of Dhaka dwellers will work unless the capital-bound migration is stopped, DSCC mayor Sheikh Fazle Noor Taposh said on Saturday. "Around 2 crore 10 lakh people live in Dhaka now. Without decentralisation this might go up by 3 crore within 2030 and 5 crore by 2041," Taposh said. All the master plans taken to increase the standard of living for the residents of Dhaka will fail if people continue to flock into the capital from outside, he said.  Read: Combing operation to help contain dengue: Taposh For this reason, the villages and suburbs of the cities should be provided with all modern facilities so that people don't have to come to the capital for the smallest of reasons, the mayor advised.  He was speaking at a seminar titled "Achievements and Future of 50 Years in Water Supply, Sanitation and Hygiene (WASH) Sector" organized by Local Government Department and Water Aid Bangladesh at the ballroom of Pan Pacific Sonargaon Hotel in the capital on Saturday.
