Gauteng will be among the most highly and densely populated cities in the world.(SABC)
International researchers say by 2050, Gauteng will be nearly as dense as Bangladesh.
Bangladesh, located in South Asia, is among the most highly and densely populated countries in the world.
Jonathan Moyer of the Joseph Korbel School of International Studies was addressing a seminar in Pretoria.
Moyer says a lot depends on government's infrastructure planning .
"Infrastructure investments take a long time so you make an infrastructure investment that pays over 30-50 year horizon and if those investments are not made at sufficient levels based on projected levels of population then there can be significant long term implications in terms of inefficiencies with traffic, electricity access, water and sanitation. Secondarily you might not build
enough schools you might not build enough hospitals so all of these things have potentially significant implications."
