Members of Sierra Leone’s National COVID-19 Emergency Operations Centre partnered with leading data science and geospatial organisations to generate timely and accurate population and infrastructure data to enhance the government’s response to COVID-19.

Freetown, Sierra Leone, 21 July 2020 — Protecting Sierra Leoneans from  -19 will  be more effective and evidence-driven, thanks to a groundbreaking new partnership that will deliver information on at-risk populations across the country.

The Government of Sierra Leone’s National COVID-19 Emergency Operations Centre consisting  of the Directorate of Science, Technology & Innovation (DSTI), Statistics Sierra Leone (Stats SL), Ministry of Information and Communication (MIC), Ministry of Health and Sanitation (MOHS) is collaborating with a coalition of international partners including GRID3, Esri, Maxar Technologies, Fraym, the Global Partnership for Sustainable Development Data and UN Economic Commission for Africa to produce crucial geospatial datasets, analyses, and tools under an open, non-commercial license to support the COVID-19 response in the country.

The most granular geospatial data in Sierra Leone’s history centre around rapid population estimates based on the country’s last census. These estimates predict how many people, as well as their age and sex, live within any given hectare area across the entire country. The data can help identify those most at risk, determine the implementation of the most efficient support and anti-COVID-19 strategies, including partial or total lockdowns, and resulting community needs. Evidence-based allocation of government resources, both at national and local levels, will particularly benefit the most vulnerable. To ensure that everyone can benefit from these groundbreaking geospatial data, the new findings are openly accessible in a national digital dashboard and COVID-19 hub which enable easy interaction and interpretation for experts and general public alike.

David Sengeh, Minister of Basic and Senior Secondary Education and Chief Innovation Officer at DSTI, explains: “These data will help us significantly to ensure the safety of Sierra Leone’s population and minimize the social and economic hardships caused by a prolonged shutdown. It allows us to accurately identify densely populated and high mobility areas, and highlight at-risk spaces where it may not be possible to adhere to physical distancing recommendations.”

The rapid population estimates are complemented by settlement information and high-resolution satellite imagery of metropolitan areas from Maxar’s Open Data Program. Using the latest technologies and methods, the data provides the government and its partners with a comprehensive picture about where people live, and their access to key infrastructure like roads or health facilities. The geospatial datasets also include information about sex and age, and shed light on various risk factors for COVID-19 infection and socio-economic vulnerability, highlighting areas and populations that have limited resources to cope with health and economic shocks.

Osman Sankoh, Statistician General, Chief Executive Officer of Stats-SL and member of Sierra Leone’s Presidential Scientific and Technical Advisory Group on Emergencies, notes: “I am proud of the role of the National Statistics Office. Upgrading our data to a higher resolution and including geospatial- temporal analyses increases the usability of our data, and ensures that Stats-SL remains the go-to national institution for credible data for national development.”

“At a time when many governments are making decisions in the dark, based on poor or no data, Sierra Leone is engaged in ambitious work with partners who can support cutting-edge approaches,” says GRID3 Sierra Leone Country Lead Annie Werner. Rhiannan Price, Maxar’s Director of the Sustainable Development Practice, adds “Forward-leaning governments like Sierra Leone are leveraging high- resolution satellite imagery to accelerate their pandemic response and better support their citizens. We are proud to assist Sierra Leone in their efforts.”

The COVID-19 response efforts build on the existing partnership between the Government of Sierra Leone, GRID3, and Maxar with the support of the Global Partnership for Sustainable Development Data the United Nations Economic Commission for Africa.

About the Data

All geospatial outputs produced by the partnership are anonymized and do not contain individual- level data. They are high-resolution data layers produced from statistical models or extracted from satellite imagery.

About the Partnership

GRID3 produced rapid population estimates, settlement extents, and provided technical support; Maxar released high-resolution imagery of Freetown, Bo, Kenema, and Makeni; Fraym developed rapid risk layers for Exposure to COVID-19 and Socioeconomic vulnerability at 1km resolution; and through the Disaster Response Program, Esri provided technical assistance and deployed a COVID-19 hub and platform for data hosting and analysis, enabling the Government to rapidly update and share data on active COVID-19 cases, create maps, dashboards, and applications to track the status of recovery of their citizens. The partnership was supported by ‘COVID-19: Data for a resilient Africa’ an initiative led by United Nations Economic Commission for Africa and the Global Partnership for Sustainable Development Data.
