Paper by Nitin Kohli, Emily Aiken & Joshua E. Blumenstock: “Personal mobility data from mobile phones and other sensors are increasingly used to inform policymaking during pandemics, natural disasters, and other humanitarian crises. However, even aggregated mobility traces can reveal private information about individual movements to potentially malicious actors. This paper develops and tests an approach for releasing private mobility data, which provides formal guarantees over the privacy of the underlying subjects. Specifically, we (1) introduce an algorithm for constructing differentially private mobility matrices and derive privacy and accuracy bounds on this algorithm; (2) use real-world data from mobile phone operators in Afghanistan and Rwanda to show how this algorithm can enable the use of private mobility data in two high-stakes policy decisions: pandemic response and the distribution of humanitarian aid; and (3) discuss practical decisions that need to be made when implementing this approach, such as how to optimally balance privacy and accuracy. Taken together, these results can help enable the responsible use of private mobility data in humanitarian response…(More)”.
Impact Inversion
Blog by Victor Zhenyi Wang: “The very first project I worked on when I transitioned from commercial data science to development was during the nadir between South Africa’s first two COVID waves. A large international foundation was interested in working with the South African government and a technology non-profit to build an early warning system for COVID. The non-profit operated a WhatsApp based health messaging service that served about 2 million people in South Africa. The platform had run a COVID symptoms questionnaire which the foundation hoped could help the government predict surges in cases.
This kind of data-based “nowcasting” proved a useful tool in a number of other places e.g. some cities in the US. Yet in the context of South Africa, where the National Department of Health was mired in serious capacity constraints, government stakeholders were bearish about the usefulness of such a tool. Nonetheless, since the foundation was interested in funding this project, we went ahead with it anyway. The result was that we pitched this “early warning system” a handful of times to polite public health officials but it was otherwise never used. A classic case of development practitioners rendering problems technical and generating non-solutions that primarily serve the strategic objectives of the funders.
The technology non-profit did however express interest in a different kind of service — what about a language model that helps users answer questions about COVID? The non-profit’s WhatsApp messaging service is menu-based and they thought that a natural language interface could provide a better experience for users by letting them engage with health content on their own terms. Since we had ample funding from the foundation for the early warning system, we decided to pursue the chatbot project.
The project has now spanned to multiple other services run by the same non-profit, including the largest digital health service in South Africa. The project has won multiple grants and partnerships, including with Google, and has spun out into its own open source library. In many ways, in terms of sheer number of lives affected, this is the most impactful project I have had the privilege of supporting in my career in development, and I am deeply grateful to have been part of the team involved bringing it into existence.
Yet the truth is, the “impact” of this class of interventions remain unclear. Even though a large randomized controlled trial was done to assess the impact of the WhatsApp service, such an evaluation only captures the performance of the service on outcome variables determined by the non-profit, not on whether these outcomes are appropriate. It certainly does not tell us whether the service was the best means available to achieve the ultimate goal of improving the lives of those in communities underserved by health services.
This project, and many others that I have worked on as a data scientist in development, uses an implicit framework for impact which I describe as the design-to-impact pipeline. A technology is designed and developed, then its impact is assessed on the world. There is a strong emphasis to reform, to improve the design, development, and deployment of development technologies. Development practitioners have a broad range of techniques to make sure that the process of creation is ethical and responsible — in some sense, legitimate. With the broad adoption of data-based methods of program evaluation, e.g. randomized control trials, we might even make knowledge claims that an intervention truly ought to bring certain benefits to communities in which the intervention is placed. This view imagines that technologies, once this process is completed, is simply unleashed onto the world, and its impact is simply what was assessed ex ante. An industry of monitoring and evaluation surrounds its subsequent deployment; the relative success of interventions depends on the performance of benchmark indicators…(More)”.
AI Investment Potential Index: Mapping Global Opportunities for Sustainable Development
Paper by AFD: “…examines the potential of artificial intelligence (AI) investment to drive sustainable development across diverse national contexts. By evaluating critical factors, including AI readiness, social inclusion, human capital, and macroeconomic conditions, we construct a nuanced and comprehensive analysis of the global AI landscape. Employing advanced statistical techniques and machine learning algorithms, we identify nations with significant untapped potential for AI investment.
We introduce the AI Investment Potential Index (AIIPI), a novel instrument designed to guide financial institutions, development banks, and governments in making informed, strategic AI investment decisions. The AIIPI synthesizes metrics of AI readiness with socio-economic indicators to identify and highlight opportunities for fostering inclusive and sustainable growth. The methodological novelty lies in the weight selection process, which combines statistical modeling and also an entropy-based weighting approach. Furthermore, we provide detailed policy implications to support stakeholders in making targeted investments aimed at reducing disparities and advancing equitable technological development…(More)”.
Cross-border data flows in Africa: Continental ambitions and political realities
Paper by Melody Musoni, Poorva Karkare and Chloe Teevan: “Africa must prioritise data usage and cross-border data sharing to realise the goals of the African Continental Free Trade Area and to drive innovation and AI development. Accessible and shareable data is essential for the growth and success of the digital economy, enabling innovations and economic opportunities, especially in a rapidly evolving landscape.
African countries, through the African Union (AU), have a common vision of sharing data across borders to boost economic growth. However, the adopted continental digital policies are often inconsistently applied at the national level, where some member states implement restrictive measures like data localisation that limit the free flow of data.
The paper looks at national policies that often prioritise domestic interests and how those conflict with continental goals. This is due to differences in political ideologies, socio-economic conditions, security concerns and economic priorities. This misalignment between national agendas and the broader AU strategy is shaped by each country’s unique context, as seen in the examples of Senegal, Nigeria and Mozambique, which face distinct challenges in implementing the continental vision.
The paper concludes with actionable recommendations for the AU, member states and the partnership with the European Union. It suggests that the AU enhances support for data-sharing initiatives and urges member states to focus on policy alignment, address data deficiencies, build data infrastructure and find new ways to use data. It also highlights how the EU can strengthen its support for Africa’s datasharing goals…(More)”.
The paradox of climate data in West Africa: growing urgency coupled with diminishing accessibility
Cirad: “In 2022, a prolonged drought devastated maize crops in northern Burkina Faso, leaving two million people without sufficient food resources. This dramatic situation could have been better anticipated and its impacts could have been mitigated with the collection and equitable sharing of specific data: that of agrometeorology, the science that studies the effects of meteorological, climatological and hydrological factors on crops.
Although it is too late to prevent the 2022 drought, protecting people from future droughts remains an urgent priority, especially in Africa, a continent where climate change poses a serious threat to rainfed agriculture, its main agricultural and economic activity.
To anticipate these climate risks, it is essential to have access to reliable meteorological data, which is crucial for ensuring sustainable and resilient agricultural practices. Yet in West Africa, the accessibility and reliability of this data are increasingly threatened and face unprecedented diplomatic, economic and security challenges…(More)”.
Crowdfunding Education
Article by Victoria Goldiee: “Nigeria’s education system has declined due to inadequate funding and facilities, low admission rates, and a nationwide shortage of qualified teachers. Consequently, receiving a quality education has become a privilege only accessible to families with financial means. According to research by the Nigeria Education and Training Services Industry, 49 percent of Nigeria’s youth enter into trade apprenticeships or expatriate to pursue a better education. In fact, Nigeria has the highest percentage of its students overseas of any African nation.
In February 2016, social entrepreneur Bola Lawal turned to crowdfunding to make educational opportunities accessible to Nigerians. He founded ScholarX as the vehicle to realize this mission through taking advantage of the largely untapped market of unclaimed scholarships, educational grants, and philanthropic donations for African students. The X in ScholarX represents the missing value and recognition that Nigerian youth deserve for their dedication to academic achievement.
“The idea for ScholarX came from the conversation with my friends on our shared experiences,” Lawal recounts, “because I also had difficulty paying for school like millions of Nigerians.” He adds that he was “even suspended from school because” of his inability to pay the tuition fee.
Like Lawal, more than 100,000 Nigerian students overseas rely on scholarships, many of which are backed either by oil and gas companies that aim to recruit students into the industry or by federal government grants for local students. But in recent years, these scholarships have been scaled back or scrapped altogether because of the ongoing economic crisis and recession. The crash of the foreign exchange rate of Nigeria’s currency, the naira, has further threatened the prospects of Nigeria’s overseas students, leaving many unable to pay tuition…(More)”
Why is it so hard to establish the death toll?
Article by Smriti Mallapaty: “Given the uncertainty of counting fatalities during conflict, researchers use other ways to estimate mortality.
One common method uses household surveys, says Debarati Guha-Sapir, an epidemiologist who specializes in civil conflicts at the University of Louvain in Louvain-la-Neuve, Belgium, and is based in Brussels. A sample of the population is asked how many people in their family have died over a specific period of time. This approach has been used to count deaths in conflicts elsewhere, including in Iraq3 and the Central African Republic4.
The situation in Gaza right now is not conducive to a survey, given the level of movement and displacement, say researchers. And it would be irresponsible to send data collectors into an active conflict and put their lives at risk, says Ball.
There are also ethical concerns around intruding on people who lack basic access to food and medication to ask about deaths in their families, says Jamaluddine. Surveys will have to wait for the conflict to end and movement to ease, say researchers.
Another approach is to compare multiple independent lists of fatalities and calculate mortality from the overlap between them. The Human Rights Data Analysis Group used this approach to estimate the number of people killed in Syria between 2011 and 2014. Jamaluddine hopes to use the ministry fatality data in conjunction with those posted on social media by several informal groups to estimate mortality in this way. But Guha-Sapir says this method relies on the population being stable and not moving around, which is often not the case in conflict-affected communities.
In addition to deaths immediately caused by the violence, some civilians die of the spread of infectious diseases, starvation or lack of access to health care. In February, Jamaluddine and her colleagues used modelling to make projections of excess deaths due to the war and found that, in a continued scenario of six months of escalated conflict, 68,650 people could die from traumatic injuries, 2,680 from non-communicable diseases such as cancer and 2,720 from infectious diseases — along with thousands more if an epidemic were to break out. On 30 July, the ministry declared a polio epidemic in Gaza after detecting the virus in sewage samples, and in mid-August it confirmed the first case of polio in 25 years, in a 10-month-old baby…
The longer the conflict continues, the harder it will be to get reliable estimates, because “reports by survivors get worse as time goes by”, says Jon Pedersen, a demographer at !Mikro in Oslo, who advises international agencies on mortality estimates…(More)”.
The Power of Volunteers: Remote Mapping Gaza and Strategies in Conflict Areas
Blog by Jessica Pechmann: “…In Gaza, increased conflict since October 2023 has caused a prolonged humanitarian crisis. Understanding the impact of the conflict on buildings has been challenging, since pre-existing datasets from artificial intelligence and machine learning (AI/ML) models and OSM were not accurate enough to create a full building footprint baseline. The area’s buildings were too dense, and information on the ground was impossible to collect safely. In these hard-to-reach areas, HOT’s remote and crowdsourced mapping methodology was a good fit for collecting detailed information visible on aerial imagery.
In February 2024, after consultation with humanitarian and UN actors working in Gaza, HOT decided to create a pre-conflict dataset of all building footprints in the area in OSM. HOT’s community of OpenStreetMap volunteers did all the data work, coordinating through HOT’s Tasking Manager. The volunteers made meticulous edits to add missing data and to improve existing data. Due to protection and data quality concerns, only expert volunteer teams were assigned to map and validate the area. As in other areas that are hard to reach due to conflict, HOT balanced the data needs with responsible data practices based on the context.
Comparing AI/ML with human-verified OSM building datasets in conflict zones
AI/ML is becoming an increasingly common and quick way to obtain building footprints across large areas. Sources for automated building footprints range from worldwide datasets by Microsoft or Google to smaller-scale open community-managed tools such as HOT’s new application, fAIr.
Now that HOT volunteers have completely updated and validated all OSM buildings in visible imagery pre-conflict, OSM has 18% more individual buildings in the Gaza strip than Microsoft’s ML buildings dataset (estimated 330,079 buildings vs 280,112 buildings). However, in contexts where there has not been a coordinated update effort in OSM, the numbers may differ. For example, in Sudan where there has not been a large organized editing campaign, there are just under 1,500,000 in OSM, compared to over 5,820,000 buildings in Microsoft’s ML data. It is important to note that the ML datasets have not been human-verified and their accuracy is not known. Google Open Buildings has over 26 million building features in Sudan, but on visual inspection, many of these features are noise in the data that the model incorrectly identified as buildings in the uninhabited desert…(More)”.
Kenya’s biggest protest in recent history played out on a walkie-talkie app
Article by Stephanie Wangari: “Betty had never heard of the Zello app until June 18.
But as she participated in Kenya’s “GenZ protests” that month — one of the biggest in the country’s history — the app became her savior.
On Zello, “we were getting updates and also updating others on where the tear-gas canisters were being lobbed and which streets had been cordoned off,” Betty, 27, told Rest of World, requesting to be identified by a pseudonym as she feared backlash from the police. “At one point, I also alerted the group [about] suspected undercover investigative officers who were wearing balaclavas.”
The speed of communicating over Zello made it the primary tool to mobilize crowds and coordinate logistics during the protests. Stephanie Wangari
Nairobi witnessed massive protests in June as thousands of young Kenyans came out on the streets against a proposed bill that would increase taxes on staple foods and other essential goods and services. At least 39 people were killed, 361 were injured, and more than 335 were arrested by the police during the protests, according to human rights groups.
Amid the mayhem, Zello, an app developed by U.S. engineer Alexey Gavrilov in 2007, became the primary tool for protestors to communicate, mobilize crowds, and coordinate logistics. Six protesters told Rest of World that Zello, which allows smartphones to be used as walkie-talkies, helped them find meeting points, evade the police, and alert each other to potential dangers.
Digital services experts and political analysts said the app helped the protests become one of the most effective in the country’s history.
According to Herman Manyora, a political analyst and lecturer at the University of Nairobi, mobilization had always been the greatest challenge in organizing previous protests in Kenya. The ability to turn their “phones into walkie-talkies” made the difference for protesters, he told Rest of World.
“The government realized that the young people were able to navigate technological challenges. You switch off one app, such as [X], they move to another,” Manyora said.
Zello was downloaded over 40,000 times on the Google Play store in Kenya between June 17 and June 25, according to data from the company. This was “well above our usual numbers,” a company spokesperson told Rest of World. Zello did not respond to additional requests for comment…(More)“
