The weather stations are mounted on mobile phone towers
Gaping gaps in weather and climate data across Africa may be filled by a partnership between humanitarian groups and mobile phone companies.
The project aims to deploy 5,000 automatic weather stations across the continent mounted on phone masts.
They will gather data on aspects of weather such as rainfall and wind, and send it to national weather agencies.
Former UN chief Kofi Annan says the project could help save lives of people on “the frontlines of climate change”.
“The world’s poorest are also the world’s most vulnerable when it comes to the impact of climate change, and the least equipped to deal with its consequences,” he said.
“Today you find cell phone towers in almost every part of Africa. We have never been able to establish weather monitoring on that scale, until now.”
Mr Annan now serves as president of the Global Humanitarian Forum, which is formally launching the programme, named Weather Info for All, at the Global Platform for Disaster Risk Reduction meeting in Geneva.
Global conversation
More than 70% of Africans make a living from farming, and the vast majority of the continent’s agriculture is rain-fed, making it highly vulnerable to variability in weather and climate.
Yet report after report has concluded that weather data – needed to make accurate projections of climate change – is in woefully short supply.
Africa has less than 200 weather stations meeting World Meteorological Organization (WMO) standards. Europe, by comparison, has several thousand.
