There is a need for regulation and sustainable urban policies that will ensure the amenities enjoyed by those living in cities trickle down into rural areas so to stem the increasing shifts into cities, Ben Campkin who is an expert and lecturer in matters to deal with urbanization from the University of London said.
Speaking at the recently concluded annual conference of Regional Centre for Mapping and Resources for Development in Nairobi, Campkin said: “The policies of urbanization in megacities will bring better sustainability for decision making”.
Most locals in Africa avoid to live in villages instead relocate to the cities where they hope to have better services including good infrastructure, beautiful sceneries and good ground for their businesses to grow.
According to research by the United Nations Population in 2010, the African population is set to double from one billion people to 2 billion by 2045. The UNDP also found that more than 720 million people living in cities over the same period. This will result in efficient technological innovation thus reducing resources and energy consumption.
In a case study that was conducted by the University of Nigeria students in 2014, putting their focus on the Lagos city, results showed that the city has a population of 10 million people. Making it the most populated city in the world this is according to world urbanization prospects UNDESA. The results also showed that the population of the city will grow by 3.2% by 2030.
The predicted urbanization growth will automatically change the currently known urbanization challenges of environmental pollution, health hazards and a positive feedback of climate change.
Nevertheless, the urbanization and population trends will require good infrastructure to be developed and expertise planning in order to cater for and sustain the growing population.
Participants noted that for holistic planning, there is a need for Geo-technologies and interdisciplinary actions which are viable for planning for the future.
