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.

Vincent Olatunji, national commissioner/CEO, NDPC, stressed the importance of safeguarding Nigeria’s digital economy through strong data protection and privacy frameworks.

He spoke while while delivering a keynote address at the IoT West Africa Conference, where he stated that the trend poses significant risks to Nigeria’s control over its digital assets.

He further described the situation as precarious for the nation’s sovereignty, and called for urgent investment in local data infrastructure.

Olatunji, highlighted data sovereignty, the growing role of data centres, and regulatory expectations under the Nigeria Data Protection Act, 2023, noting both the benefits of compliance and the risks of non-compliance. Olatunji underscored that data centres are now critical infrastructure for Nigeria’s digital transformation.

While decrying that over 90 percent of the Nigeria’s data is hosted abroad which is precarious for the nation’s sovereignty he encouraged for more investment in the sector as it is projected to reach $1.9 billion by 2031.

Also speaking, Kashifu Inuwa, the director-general of the National Information Technology Development Agency (NITDA), said policy is emerging as the key driver of Nigeria’s digital transformation, particularly in shaping the development of the Lagos-Abuja digital corridor.

“While infrastructure responds to demand, policy creates the enabling environment for sustainable growth,”

Inuwa who was represented by Aristotle Onumo, director, stakeholders management and partnership at the IoT West Africa Conference in Lagos, on the theme “The Lagos-Abuja Digital Corridor: Building Africa’s Next Data Centre and Cloud Hub.”

Inuwa emphasised that while infrastructure responds to demand, policy remains the critical driver that creates an enabling environment for sustainable digital growth.

He explained that Nigeria’s broadband policy, which stipulates minimum speeds of 10 Mbps for rural areas and 25 Mbps for urban centres, provides a strategic framework for prioritising infrastructure deployment along the Lagos-Abuja digital corridor.

He cautioned, however, that without deliberate collaboration and partnership between government, the private sector, and civil society, widespread infrastructure rollout would remain challenging. “Collaboration is the pathway that massifies impact, while partnership harnesses collective intelligence. No one can achieve this in isolation,” he said.

Inuwa also spoke on the Nigerian Sovereign Cloud Project; a flagship initiative aimed at strengthening indigenous cloud service providers and preventing the dominance of Nigeria’s digital infrastructure by foreign hyperscale operators.

By scaling local infrastructure to meet global standards, the project seeks to domesticate data hosting, reduce operational costs, and improve access to cloud services across the country.

How Nigerians Search is Changing — and Why it Matters for Our Businesses

Published

By Olumide Balogun

There was a time when using a search engine felt like cracking a code. You typed two or three carefully chosen keywords, hoped the machine understood, and waited to see what came back. People had to learn the language of machines, shrinking complex needs into stilted phrases.

How Nigerians search is changing — and why it matters for our businesses

Olumide Balogun, Director, West and East Africa at Google.

That era is ending. Today, a person can ask a question the same way they would ask a colleague, and the technology is finally learning to respond in kind. Nowhere is this shift more visible than in Nigeria, where a young, mobile-first population expects tools to keep pace with how they actually think and speak.

This change carries weight far beyond convenience. It is reshaping how Nigerian businesses reach customers and how customers find what they need.

For years, marketing online meant wrestling with rigid keyword lists. A small business owner had to guess every possible phrase a customer might type. If you sold ankara dresses, you tried “ankara dress,” “Nigerian print fabric,” “traditional wear Lagos,” and a dozen variations, hoping you covered the gaps. Anything you missed was a missed customer

The new wave of conversational search makes those lists feel ancient. People now ask layered, specific questions: “Where can I find a sustainable tailor in Yaba who makes office wear?” Older systems would have stumbled on a query like that. Newer ones, powered by artificial intelligence, can read intent and stitch ideas together. They connect a question to a relevant local website that a basic keyword search might never have surfaced.

The shift is starting to show up in concrete tools. Google’s AI Max for Search ads, now a year old, is one of the more visible examples. In plain terms, it lets a business describe what it sells and who it serves in everyday language, and the system figures out which searches to match it to, instead of forcing the owner to write hundreds of keywords by hand. Early adopters report stronger revenue growth than peers, and users say results feel more useful because the technology connects ideas for them, often surfacing local sites that would not have appeared before.

There is a quieter benefit too. When advertising becomes more relevant, it stops feeling like an interruption. An ad that answers a real question is no longer noise; it is information. That changes the texture of the internet. The marketplace gets less cluttered, and people spend less time wading through results that do not fit what they were looking for.

None of this is automatic. The technology only works if it can understand human nuance, and human nuance in Nigeria is not the same as human nuance in California. A search for “owambe outfit” or “small chops for fifty people” demands cultural context, not just linguistic translation. Newer features try to bridge that gap. AI Brief, a part of the same Google toolkit, lets a business owner type plain instructions, like “focus on sustainable traditional wear, keep a premium tone,” and the system follows them. This is steering by intent, not by keyword bingo.

There are gains for businesses with deep catalogues too. A retailer with thousands of items no longer has to match every question to the right page by hand. Tools such as Google’s Final URL Expansion read the search and send the customer straight to the page that fits, in real time. In travel, finance, and healthcare, where compliance matters, the same systems can carry mandatory legal text into every ad automatically. Regulated industries can grow without cutting corners.

These are not abstract wins. They are the difference between a small business being found by a customer in Abuja at 9 p.m. and being lost in a sea of generic results, between a hospital reaching the right patient and a tailor in Surulere being discovered by a bride planning her wedding.

We should not pretend the transition is finished. AI is imperfect. It can misread context, amplify mistakes, and require careful oversight. Regulators, businesses, and users all have a role in shaping how it develops in our market. The broader direction, however, is clear, and it is one Nigeria should engage with rather than resist.

Nigeria is a nation of storytellers and traders. Our markets, physical and digital, have always been about conversation. The technology of search is finally beginning to mirror that. It is becoming less of a vending machine and more of a market stall, where you can ask a question, get a real answer, and discover something you did not know you needed.

That is the bigger story behind any single product launch. It is about how a country full of voices is finding new ways to be heard. For Nigerian businesses willing to adapt, the opportunity has never been clearer.
