Using AI to Map Africa and Beyond
Did you know that by 2050, the world’s urban population is expected to grow by 2.5 billion, with nearly 90% of that growth happening in cities across Africa and Asia? To keep up with this rapid urbanisation, governments, humanitarian organisations, and researchers need accurate information on buildings and infrastructure.
This data helps plan for future growth, respond to crises, and ensure resources are distributed fairly. But in many parts of Africa and the Global South, this vital information is outdated or simply unavailable.
That’s why Google launched the Open Buildings project in 2021. It started at the AI Research Lab in Accra, Ghana, and has helped map 1.8 billion buildings across Africa, Asia, Latin America, and the Caribbean—about 40% of the globe. This data has been used by governments, NGOs, and researchers to improve services and respond to disasters.
Real-world examples:
In Uganda, the nonprofit Sunbird AI used our data to prioritise areas for rural electrification, ensuring that towns and homes most in need received power first.
WorldPop, a team from the University of Southampton, has integrated the Open Buildings data into their population estimates. These estimates are being used by UN agencies and governments, including in Nigeria, where the data has helped identify areas where children haven’t received routine immunizations.
Now, we’re expanding this effort with the Open Buildings 2.5D Temporal Dataset, which doesn’t just map buildings—it shows how they change over time and estimates their heights. This new data covers the years 2016 to 2023, offering a detailed picture of how cities and settlements across Africa and the Global South have grown. This is crucial for urban planning, disaster response, and understanding population density.
Governments and organisations can use this data in various ways:
Flood preparedness: In flood-prone areas, accurate data can help authorities predict which buildings and neighbourhoods are most at risk.
Urban growth: In cities like Kumasi, Ghana, which has seen rapid expansion, this data allows city planners to better manage resources and infrastructure.
Disaster recovery: In places like Palu, Indonesia, where a tsunami struck in 2018, this data shows how the built environment changed before and after the crisis, helping rebuild communities more effectively.
How we built this dataset:
We used AI to improve the quality of low-resolution satellite images and estimate the size and height of buildings. This is important because higher-resolution satellite images are not always available for the Global South. With this technology, we’ve created a detailed map of over 58 million square kilometres, covering parts of Africa, Latin America, South, and Southeast Asia.
Why this matters:
Maps are a lifeline. They help governments, humanitarian agencies, and researchers ensure that everyone is counted and represented. With this new dataset, we’re giving these organisations better tools to plan for the future, respond to crises, and support communities in need.
We invite researchers, policymakers, and anyone interested in urban development to explore the Open Buildings 2.5D Temporal Dataset on Google Earth Engine and share their feedback with us.

Kaspersky Cybersecurity Experts Warn of Evolving Holiday Scams
With the holiday season here, it’s not only a time for magic and celebration but also a prime opportunity for fraudsters to exploit the festive rush for gifts and bargains.
Amid the sparkle of year-end celebrations, cybersecurity experts at Kaspersky have identified several prominent scams targeting consumers across various regions and languages.
Fake holiday shops
Deceptive online stores mimic the look and feel of legitimate e-commerce sites, offering seasonal items such as decorations, gifts, and even trees at steep discounts.
These sites often appear highly localised, adapting their language and currency based on the user’s geographic location, leveraging data extracted from browsers.
Victims typically encounter these stores by following links in ads or pop-ups.
These sites aim to steal funds. Often, these fraudulent stores exist only for a short period, as they get flagged by the vendors of goods.
Free mobile data offer
This scam plays on the allure of free services, claiming to provide free mobile data valid across all major telecom providers.
In order to receive the free data, victims are required to share the promotion link with 10–15 contacts via WhatsApp, ensuring the scam spreads exponentially.
After sharing, victims are prompted to enter their personal details — name, phone number, and email — into a form.
The collected data is then sold on the Dark Web or used in other fraudulent activities.
In some cases, victims unknowingly download malware that compromises their devices, leading to further exploitation.
Holiday payments on behalf of government agencies
Fraudsters impersonate government authorities, promising fictitious payments in celebration of the holidays.
This scam has been reported in several African countries, including Kenya and Nigeria.
To receive payment, victims are directed to fill out a survey which requires personal details like name and phone number.
Once the survey is completed the user is asked to share the link to the announcement with their connections via WhatsApp.
These details are collected and added to fraudulent databases, then sold to third parties or used for phishing attacks and identity theft.
This scam exploits trust in government systems and the festive spirit of giving.
Christmas recipe scam
This scam begins with a seemingly harmless email promoting a holiday cake recipe.
Victims are encouraged to pay a small fee to access the recipe.
Once payment is made, the victim’s credit card information is stolen. The fraudsters also collect other personal information essential for accessing banking services.
“Holiday scams are not a new phenomenon, but they have evolved to become increasingly sophisticated, leveraging regional traditions and technology to exploit unsuspecting victims.
The rush of the holidays makes people more vulnerable — they’re distracted, eager to grab a deal, or trust promotions that align with festive themes. Cybercriminals are not just stealing money — they’re building massive databases of personal information that fuel future fraudulent schemes.
The holiday season is a time for joy and giving, but users need to remain vigilant to ensure they’re not unknowingly giving fraudsters the tools to exploit them further,” said Olga Svistunova, Senior Web Content Analyst at Kaspersky.

Hackers Seize NBS Newly Redesigned Website
Cybercriminals have persisted in targeting Nigerian government websites, with the most recent attack on the National Bureau of Statistics (NBS).
The NBS confirmed the development in a brief statement posted on its X (formerly Twitter) account
It said that its newly redesigned official website has been hacked.
The NBS disclosed the incident and assured the public that efforts are underway to recover the website.
It urged the public to disregard any messages or reports posted until the full recovery of its website.
The statement on X read: “This is to inform the public that the NBS website has been hacked, and we are working to recover it. Please disregard any message or report posted until the website is fully restored.”
The NBS plays a vital role in Nigeria’s development, serving as the official statistical agency responsible for collecting, analyzing, and disseminating statistical data on the country’s economy, governance, and development
This marks the latest in a series of attacks on Nigerian government websites, a trend that has been ongoing for some years.
From government ministries to officials, cyberattacks in Nigeria have surged to alarming levels, with even financial institutions falling victim.
The Nigerian Communications Commission (NCC) and National Information Technology Development Agency (NITDA) frequently issue warnings of cybercriminals targeting individuals, government entities, banks, and telecom companies.
