Facebook is working closely with key non-profit and research partners to use artificial intelligence (AI) and big data to address large-scale social, health and infrastructure challenges in sub Saharan Africa. These efforts range from rural electrification in Tanzania to vaccinating people in remote corners of Malawi.

Facebook is applying the processing muscle of its compute power, its extensive data science skills and its expertise in AI and machine learning to create the world’s most detailed and accurate maps of local populations. Facebook also partners with Columbia University’s Center for International Earth Science Information Network (CIESIN (http://www.ciesin.org/)) to ensure that this effort leverages the best available administrative data for all countries involved.

The Boston-based Facebook team uses advanced computer vision and machine learning to combine satellite imagery from Digital Globe with public census data and other sources to create detailed population density maps of Africa. Using Facebook’s machine learning capabilities, Facebook started developing population density maps to provide better tools to support connectivity efforts around the world. No Facebook data has been or will be used in the project and the census and satellite data used contain no personally identifiable information.

High-resolution satellite imagery already exists for much of the world. However, prior to Facebook’s mapping project, it would have required countless hours for volunteers to comb through millions of square miles of pictures to identify which contained a tiny town or remote village.

The Facebook team used AI to solve that problem, efficiently crunching through data at a petabyte scale. For Africa alone, for example, the computer vision system examined 11.5 billion individual images to determine whether they contained a building. The team found approximately 110 million buildings in just a few days.

“Having started my career at USAID working on malaria control, I have witnessed first-hand the critical role that accurate data plays in the effectiveness of humanitarian efforts,” says Laura McGorman, a public policy manager at Facebook. “What’s exciting about projects like these that they provide an opportunity for our company to contribute to these efforts through our expertise in data and machine learning.”

In Malawi, the Missing Maps Project used these AI-powered maps to filter out the 97% of the terrain that is uninhabited. This helped to coordinate the efforts of 3,000 Red Cross volunteers in Malawi who visited roughly 100,000 houses in just three days to educate people about measles and rubella vaccines.

“The maps from Facebook ensure we focus our volunteers’ time and resources on the places they’re most needed, improving the efficacy of our programs,” says Tyler Radford, executive director of the Humanitarian OpenStreetMap Team, which is part of the Missing Maps Project.

In addition to assisting the Red Cross and Missing Maps Project in Malawi, the maps have been used by aid groups like the Bill and Melinda Gates Foundation, the World Bank, and Humanitarian OpenStreetMap. In Tanzania, Facebook’s AI-powered maps helped kick-start efforts to bring renewable electrification to rural areas.

To understand which locations would benefit most from decentralized energy solutions, the Humanitarian OpenStreetMap Team collaborated with the Reiner Lemoine Institut and Integration Environment and Energy to combine Facebook’s population maps with detailed data on settlement locations and structures from OpenStreetMap.

Humanitarian OpenStreetMap team personnel then travelled to villages identified as high priority and conducted surveys to understand the populations’ electricity needs. The results of these surveys were provided to agencies involved in rural electrification, helping mini-grid operators choose the most appropriate locations to begin the work.

The Facebook population density maps project now aims to keep adding new continents and countries.

An artificial intelligence (AI) application has been developed to help combat the spread of fake news, misinformation and political propaganda as political activities gradually build toward the 2027 general elections in Nigeria.

Tech Expert Unveils BAT-BOT AI App to Curb Fake News ahead of 2027 Elections

The app, known as BAT-BOT AI, was unveiled in Abuja by Mr. Gunu Usman, its founder, who said the platform is designed to assist the federal government in addressing the growing challenge of false information within nation’s digital space.

‎Mr Usman explained that the new platform was created to ensure that factual information circulates faster than falsehood.

He noted that the rapid spread of misinformation, disinformation, hate speech and manipulated narratives targeting the administration of Bola Tinubu, the ruling All Progressives Congress, and national institutions poses risks to democratic stability and public trust.

According to Mr. Usman, BAT-BOT AI was developed to support public access to verified information while countering misleading narratives online.

The Technology expert described the system as a sovereign AI-powered civic information and fact-verification platform designed to strengthen Nigeria’s digital information ecosystem ahead of the 2027 general election.

He added that the initiative aligns with the government’s policy direction under the Renewed Hope Agenda of President Tinubu, which seeks to promote transparency and encourage informed civic participation.

The founder further explained that the platform is currently accessible to Nigerians through multiple digital channels, enabling users to verify claims, seek clarification on government policies and obtain information on national development initiatives.

Mr.  Usman expressed optimism that the tool would help curb the spread of false information and contribute to a more credible digital environment as the country prepares for the next electoral cycle.

Over the past four years, gold has risen by more than 400%. The precious metal has long been one of the most traded assets in global financial markets. From its role as a traditional store of value to its sensitivity to inflation, interest rates, and geopolitical uncertainty, gold continues to attract traders seeking efficient and predictable trading opportunities during a period of global uncertainty and high volatility.

Why JustMarkets Is a Strong Choice for Gold Trading

Gold is recognized for its volatility, especially during the day, especially with economic announcements or geopolitical events. Speed is of the essence in volatile markets. JustMarkets provides high-speed execution of orders, which helps minimize the risks of delays, especially during periods of high volatility.

Microsoft is stepping up its push to expand artificial-intelligence adoption across Africa as competition intensifies with Chinas DeepSeek for influence in one of the worlds youngest and fastest-growing digital markets.

Microsoft Expands Africa AI Push while DeepSeek Gains Users

The company plans to train 3 million Africans on its AI technologies this year through partnerships with schools, universities and other institutions, with a focus on South Africa, Kenya, Nigeria and Morocco.

The effort reflects Microsofts broader attempt to accelerate adoption of its AI ecosystem across emerging markets where developers and enterprises are increasingly experimenting with generative AI tools.

Alongside the training initiative, Microsoft is working with MTN Group (MTNOY), Africas largest telecommunications company, to distribute Microsoft 365 and its Copilot digital assistant to about 300 million subscribers.

The Elevate program is designed to expand AI literacy and reduce cost barriers that might otherwise limit adoption, according to regional leadership.

The push comes as Chinese technology firms expand their footprint across the continent, with DeepSeeks open-source models accounting for roughly 11% to 14% of chatbot use in several African markets and reaching about 20% in countries such as Ethiopia and Zimbabwe following investments tied to digital infrastructure and telecom networks.

Microsoft is also increasing its infrastructure investment in the region.

In South Africa, the company plans to invest 5.4 billion rand, or about $330 million, to expand its cloud and AI capacity by the end of next year, while it is also exploring plans for a geothermal-powered data center in Kenya.

Early corporate adoption is emerging across the continent, with South African grocer Spar Group using Copilot in ways that save more than 700 employee hours annually and Nigerias Access Holdings integrating AI into daily workflows.

Regional leadership has suggested broader AI adoption could potentially contribute up to $1.5 trillion to Africas gross domestic product by 2030 if governments and businesses continue investing in digital infrastructure and AI skills.
