Fresh, on-the-ground evidence from health planners and climate analysts in Rwanda, Nigeria and South Africa shows how the Open Buildings dataset, which maps more than 1.8 billion structures, is helping frontline projects close service gaps and strengthen community resilience.

Across the continent, artificial-intelligence tools are graduating from pilots to public-service workhorses, powering everything from crop-price forecasts to live language translation. Open Buildings—developed by researchers at Google Research Africa—is part of that shift, proving that open, locally guided AI can turn sparse data into timely decisions without locking African problem-solvers behind paywalls or proprietary gates.

In Rwanda, the Ministry of Health and Kigali-based Sand Technologies resited rural clinics with help from the dataset. Their new blueprint aims to bring 92% of citizens within a 30-minute reach of care, trimming journeys that put mothers and newborns at risk.

Across Northern Nigeria, epidemiologists at AFENET and geographers from WorldPop uncovered 10,250 buildings, guiding vaccinators who reached 70% of the zero-dose and under-immunized children identified through the mapping in just six months.

Meanwhile, the World Resources Institute (WRI) has already applied this flood-risk modelling in Dire Dawa, Kigali, Musanze, Gqeberha and Johannesburg, combining two-dimensional hydraulic simulations with building footprints to create block-by-block exposure maps.

The need is pressing: Nairobi is still recovering from the May 2024 floods that displaced more than 278 000 residents, while Johannesburg’s rapid growth along the flood-prone Jukskei River continues to heighten vulnerability

These projects tackle challenges felt across the continent. Africa still has about 8.7 million “zero-dose” children who receive no routine vaccines each year, while the urban population is projected to almost double to nearly one billion people by 2035— forcing new homes into high-risk floodplains and informal settlements.

By giving ministries, city engineers and NGOs a street-level view of where communities are growing and how they change over time, the Open Buildings dataset lets limited budgets flow to the people and places that need them most.

Dr Aisha Walcott-Bryant, Research Scientist & Head, Google Research Africa, “These projects show what happens when local expertise meets open, scalable technology: mothers reach clinics sooner, children receive long-overdue vaccines, and city planners get ahead of the next flood.

“We’re thrilled to stand beside partners who turn data into decisive action, proving that AI’s highest calling is to solve real-world challenges.”

From lifesaving clinics to climate-smart cities, these projects show how open AI is fast becoming Africa’s quiet engine for equitable progress.

The Open Buildings dataset—along with sample code, tutorials and its new 2.5D layer—is freely available at g.co/openbuildings.

The International Rescue Committee (IRC) has announced the formation of Airbel Ventures, a new humanitarian impact investing fund aimed at accelerating the introduction and scaling of breakthrough technologies in crisis-affected communities.

The fund will invest in companies whose ideas have the potential to change humanitarian response, including digital infrastructure for frontline health systems and climate-resilient agriculture.

The launch of Airbel Ventures follows a period of rapid innovation at the IRC, despite the humanitarian sector facing record funding cuts.

In the past year, the IRC’s Airbel Impact Lab has advanced more than twenty Artificial Intelligence (AI) and technology initiatives—from anticipatory action tools powered by climate and vulnerability data, to frontline service delivery using safe, orchestrated AI systems, to breakthrough diagnostic tools for emerging diseases.

Airbel Ventures’ first impact investment is in Signalytic, a company delivering solar-powered computing devices that ensure reliable electricity and connectivity for remote health facilities.

Following the investment, the IRC will pilot Signalytic’s technology with its Nigeria Health team, demonstrating the viability of next-generation digital infrastructure in humanitarian settings.

“We know breakthrough solutions already exist—what’s missing is the path to scale in humanitarian contexts,” said Dr. Jeannie Annan, Senior Vice President for Research & Innovation at the IRC and head of the Airbel Impact Lab.

MTN Nigeria Suffers 9,218 Fibre Cuts in 2025 as Vandalism, Theft Cripple Network

MTN Nigeria, the country’s largest telecommunications operator, recorded a historic surge in network disruptions in 2025, suffering 9,218 fibre cuts as of December 31, alongside 211 base station sites affected by theft and vandalism, incidents that disrupted mobile and data services relied upon daily by millions of Nigerians.

MTN Nigeria Suffers 9,218 Fibre Cuts in 2025 as Vandalism, Theft Cripple Network

The data was revealed by Dr Karl Toriola, chief executive officer/managing director, MTN Nigeria via a social media post titled ‘MTN Nigeria 2025 Wrapped’.

The scale of the damage highlights the growing vulnerability of Nigeria’s telecommunications infrastructure, which has come under increasing pressure from road construction activities, cable theft and deliberate acts of vandalism.

MTN said 5,478 fibre cuts occurred within just the first seven months of 2025, with 760 incidents recorded in July alone, underscoring the intensity of the challenge.

Some of the incidents had wide-ranging consequences, knocking out connectivity across multiple states simultaneously and affecting voice calls, data services, digital payments and enterprise operations.

The company described the situation as a national infrastructure problem, rather than an isolated corporate issue, given the economy’s deep dependence on mobile networks.

“These gaps were shaped by real operational challenges such as fibre cuts, theft, and vandalism. Their impact is felt directly by customers and reflected in what they tell us,” Toriola,

The disruptions were reflected in customer feedback volumes, as MTN handled an unprecedented number of complaints during the year. The operator said it resolved 1,624,263 customer complaints in 2025, spanning call centres, social media platforms, emails and physical service centres nationwide.

Despite the setbacks, MTN pointed to signs of operational resilience. The company retained its ranking as Nigeria’s best network by Ookla, returned to profitability after a challenging period, declared an interim dividend, and expanded its subscriber base to over 85 million users by September 2025.

The figures show that while Nigeria’s telecom operators continue to invest heavily in network expansion and customer service, infrastructure sabotage remains a major drag on service quality and operating costs.

MTN acknowledged that performance improvements remain a work in progress. “We are not where we want to be yet. We see you. We hear you. We exist because of you. And we will get better,” Toriola said.

As the company enters its 25th year of operations in Nigeria, Toriola said MTN is doubling down on customer-centricity, treating every piece of feedback as a guide for improvement, while also stepping up engagement with government agencies.

The CEO renewed calls for stronger regulatory and legal protections for telecommunications infrastructure, urging policymakers to classify fibre cables, base stations and other critical assets as national infrastructure and criminalise vandalism to deter repeat attacks.

The newly licensed firms are Intellvision Technologies Limited, Granet Technologies Limited, Fiber Sonic Limited, Dasol Solution Services Ltd, Boost ISP Limited, and Amazon Kuiper Nigeria Limited.

Five of these companies are headquartered in Lagos, while Granet Technologies Limited operates from Owerri in Imo State, highlighting the persistent concentration of broadband infrastructure in major commercial hubs like Lagos, Abuja, and Port Harcourt.

This development intensifies competition in Nigeria’s broadband market, which faces pressure from dominant mobile network operators such as MTN and Airtel, alongside rapid expansion by satellite providers like Starlink.

Traditional ISPs continue to grapple with shrinking customer bases, aggressive data pricing from telcos, and satellite disruptions, even as NCC data from Q2 2025 showed Spectranet, Starlink, and FibreOne controlling about 65 per cent of the 313,713 active ISP subscribers.

The inclusion of Amazon Kuiper Nigeria Limited marks a significant entry of global satellite broadband competition, building on Nigeria’s recent approvals for other low Earth orbit providers to enhance connectivity in underserved areas.

Industry analysts view the licences as a strategic push to improve internet quality amid rising demand for digital services, though geographic clustering underscores ongoing infrastructure challenges outside urban centres.

NCC’s move aligns with broader efforts to foster a competitive telecoms sector critical to Nigeria’s digital economy ambitions.
