Using AI to Map Africa and Beyond

Published

Kindly share this post

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 But in many parts of Africa and the Global South, this vital information is outdated or simply unavailable.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.

FG Plans to Link Social Register to NIN for Humanitarian Crisis

Kindly share this post

Federal government has disclosed that efforts are ongoing to link the National Social Register (NSR) to the National Identity Numbers (NIN).

FG Plans to Link Social Register to NIN for Humanitarian Crisis

Prof. Nentawe Yilwatda, minister of Humanitarian Affairs and Poverty Reduction, explained that the linked data would assist the country to anticipate crises, mobilize resources faster, and ensure aid reaches those who need it the most.

He said harnessing data would save the country and relevant stakeholders the stress and bottlenecks of outdated processes.

He also identified bureaucratic crisis as the biggest crisis in the humanitarian space which stalls responses to humanitarian issues.

Speaking in Abuja on Tuesday at the National Humanitarian Roundtable programme, the minister said: “People are traumatized by climate change, security threats and economic shock across the country and in the midst of these, we have limited funding.

“The biggest crisis we have is not just the people being killed, the crisis we have is a bureaucratic crisis that does not respond to a humanitarian crisis. Every delay in decision making, every inefficiency in coordination, every shortfall in funding, costs the life of people.

“They say knowledge is power, but knowledge can be destructive too. It can only be power if we use it effectively. By leveraging data and technology, we can anticipate crises; we can mobilize resources faster and ensure aid reaches those who are in need the most and without the bottleneck of outdated processes.

“We are linking the social register to national identity numbers and geotagging all homes of those who are vulnerable across the country so that if there’s any crisis, we don’t need to begin to walk around communities and taking names and asking the States Emergency Management Agency and the National Emergency Management Agency (NEMA) for data.

Nigeria Tops as INTERPOL Arrested Over 300 Cybercriminals Across Africa

Published

on

Kindly share this post

Kaspersky has recently contributed its threat intelligence data to an INTERPOL-led law enforcement action that aimed to disrupt cross-border criminal networks across the African region that cause significant harm to individuals and businesses.

With seven participating countries in Africa, operation Red Card resulted in the arrest of 306 individuals suspected of links to cybercrimes such as mobile banking, investment and messaging app scams, and seizure of 1,842 devices.

Conducted from November 2024 to February 2025, operation Red Card was delivered through INTERPOL’s African Joint Operation against Cybercrime (AFJOC) and brought together law enforcers from Benin, Côte d’Ivoire, Nigeria, Rwanda, South Africa, Togo and Zambia.

The operation conduct was preceded by a threat intelligence data exchange, which was enriched by INTERPOL and its private sector partners, including Kaspersky. Kaspersky has shared with the law enforcement agency the results of an analysis of samples of a malicious Android application that targeted users in African countries along with the data on related infrastructure.

Altogether, the cybercriminal cases uncovered by the Red Card participants have preyed on more than 5,000 people. Among operation highlights were:

Nigeria: Nigerian police arrested 130 people, including 113 foreign nationals, for their alleged involvement in cyber-enabled scams such as online casino and investment fraud. The suspects, who converted proceeds to digital assets to conceal their tracks, were recruited from different countries to run the illegal schemes in as many languages as possible.

Zambia: Officers apprehended 14 suspected members of a criminal syndicate that hacked into victims’ phones. The scam involved sending a message containing a malicious link which, when clicked, installed malware on the device.

This allowed hackers to take control of the messaging account, and ultimately the phone, giving them access to banking apps. The hackers were also able to use the victim’s messaging apps to share the malicious link within conversations and groups, enabling the scam to spread.

Rwanda: Rwandan authorities arrested 45 members of a criminal network for their involvement in social engineering scams that defrauded victims of over USD 305,000 in 2024 alone.

Their tactics included posing as telecommunications employees and claiming fake ‘jackpot’ wins to extract sensitive information and gain access to victims’ mobile banking accounts. Another method involved impersonating an injured family member to ask relatives for financial assistance towards hospital bills.

South Africa: Local authorities arrested 40 individuals and seized more than 1,000 SIM cards, along with 53 desktops and towers linked to a sophisticated SIM box fraud scheme. This setup, which reroutes international calls as local ones, is commonly used by criminals to carry out large-scale SMS phishing attacks.

Neal Jetton, INTERPOL’s Director of the Cybercrime Directorate, said: “The success of Operation Red Card demonstrates the power of international cooperation in combating cybercrime, which knows no borders and can have devastating effects on individuals and communities.

“The recovery of significant assets and devices, as well as the arrest of key suspects, sends a strong message to cybercriminals that their activities will not go unpunished.”

“Kaspersky is proud to be part of this collaborative effort led by INTERPOL. The evolving threat landscape in Africa requires a multi-stakeholder dialogue and joint efforts of public and private organisations to address the cybersecurity challenges the region faces today.

The Red Card operation is a notable example of such cooperation, showcasing how the expertise of private companies coupled with extensive investigative capacities of law enforcers can foster a more cyber-resilient environment,” comments Yuliya Shlychkova, Vice President, Global Public Affairs, Kaspersky.

Kaspersky and INTERPOL have a vast record of joint operations aimed at combating cybercrime in the African region, with Kaspersky having supported two editions of INTERPOL’s Africa Cyber Surge operations.

Just recently, Kaspersky was also a contributor to INTERPOL’s joint action with AFRIPOL, which last year became the company’s official partner in fostering a more cybersafe climate across Africa. This partnership focuses on sharing Kaspersky’s extensive data on local cyberthreats and cybercrime trends in the region.
