What could be the remote and immediate courses to theses urban challenges? What is the best evaluation technique to assess the effectiveness of these institution?
Inequity and segregation seem to be common challenges to cities all over the world. Urban inequity and segregation are also an indication of global inequity. While more and more cities want to focus on services and hi-tech, the dirty work of the world remains to be done in the poorest cities with the most meager resources to develop.
Firstly I would like to say some issue from Japan's books on geography: In the 1980s, Krasen proposed a circulation model of “urban development stage theory” through analysis of data from 148 European cities. This is because the city is “urbanization → suburbanization → counter-urbanization → reurbanization → urbanization”... There are many guild-line policies mentioned in Tokyo Master Plan, such as networked compact city, functional urban polycentricity...
Not only cities Global south, many mega-cities in South-Asia are facing to the urban problems, traffic congestion, poverty, due to the capital cities' centralization.
Then, let's go back to your question. Unlike China's strong national macroeconomic regulation and rapid development of infrastructure, Japan's systematic cautious master plan, EU's loose polycentric urban system, US's broad highways and aviation systems, many mega-cities in global south need to learn the experience from above-mentioned developed countries or China, towards the SDGs of urban development. Just a little idea here.
If only informed decisions about the environment can be somebody with the use of geopatial tools and technioogies, and action plans are implemented with conformity to the important factors, not only in Global south but in Nigeria as well.
