Africa should leapfrog high tech to solve infrastructure problems
INTERNATIONAL – From solar-powered ground pumps to 3D-printed filters, new technology can help solve water shortages in African cities facing rapid growth, entrepreneurs and policymakers said.
These were among the solutions discussed at a summit hosted by the Islamic Development Bank in Senegal’s capital, Dakar, last week, focused on how innovation can help African cities cope with the pressures of climate change and population growth.
One in three people in Africa lacks access to a clean, reliable water source, and the figure is rising, according to the World Health Organisation, which estimates that poor sanitation causes 115 deaths each hour on the continent.
African countries should leapfrog old technology rather than playing catch-up when it comes to urban infrastructure such as water and transport, said Senegal’s President Macky Sall.
“Africa’s delay in terms of urban management offers us the opportunity to take advantage of a new generation of available technology,” Sall said, speaking yesterday at the Islamic Development Bank’s “Transformers Summit”.
Senegal’s urban residents are projected to reach 60 percent of the total population in 2030, up from 43 percent in 2013, according to the World Bank, as agriculture suffers from the impacts of climate change and people increasingly moving to cities in search of jobs.
But like many African countries it lacks the infrastructure to support the shift. Outside the capital, only two-thirds of urban households were connected to the water network and one-third to sewage systems in 2016, the World Bank said.
To remedy this, Senegal launched a CFA Franc 30 billion (R736 million) fund for entrepreneurship last year. The Islamic Development Bank, which is based in Saudi Arabia, also launched a $500m (R7.24bn) “Transform Fund” for entrepreneurship in 2018.
Among the 34 Transform Fund recipients who attended the conference, at least nine had projects relating to water access.
“This is something that is not going to be solved unless you get private capital involved,” said Christelle Kwizera, founder of a water treatment and distribution company in Rwanda, adding that the main obstacle for African governments is lack of funds.
Kwizera’s company Water Access Rwanda reclaims broken hand pumps and turns them into solar-powered kiosks that pipe water to homes, she said. It currently has 57 000 daily users.
Mauricio Cordova, another entrepreneur, started his company Fair Cap in Peru with the goal of providing clean water to people affected by floods, cyclones or other disasters.
He and his team used open-source design and 3D printing to create a small portable filter that screws on to plastic water bottles like a cap. A larger model was tested in Mozambique after Cyclone Idai this year, and is in production.
“The problem is so big, I think we need many solutions,” he said.
