This paper investigates the effect of urbanization on household food security in Mali by using both objective (per capita food expenditure) and subjective (Household Hunger Scale) measures. The data set consists of 9,782 households surveyed in February 2018 under the national food security and nutrition survey (ENSAN) conducted by Mali’s Early Warning System (SAP). The findings indicate that urban households are less food secure than rural ones: urbanization significantly decreases food expenditure per capita and increases the likelihood of being food insecure (mild to moderate). Key explanatory factors include low and irregular urban incomes, heavy dependence on purchased food, and limited own-food production. The authors suggest policymakers should target urban poor households in food safety nets and social protection schemes.

This article introduces an open-access and highly detailed dataset on temporary migration in Senegal, derived from mobile phone data collected by the operator Sonatel between 2013 and 2015. It provides measures of migration flows and stocks across 151 locations every half-month, focusing on movements lasting between 20 and 180 days. By overcoming the limitations of conventional surveys, the authors present an algorithmic framework that detects migration events from digital traces and distinguishes between daily, temporary, and permanent mobility. The dataset, methodologically validated, represents a unique resource for scholars and policymakers to analyze internal mobility patterns, resilience to economic or climatic shocks, and regional planning dynamics. This approach also offers a scalable model for migration statistics generation in other developing contexts.

This Policy Brief by Sten Hagberg examines the effects of population displacement on the rapid urbanisation of secondary cities in the Sahel, focusing on Burkina Faso, Mali, and Niger. It discusses the strain on public services, the growth of informal settlements, shifting family and gender dynamics, and the securitisation and mistrust targeting displaced populations. Displaced persons mostly seek refuge in under-resourced regional cities. The Brief highlights political tensions around official displacement categories and promotes analysis through “practical norms” — real-life social and urban governance practices. It concludes with a call for more qualitative research to better understand these urban dynamics and support displaced populations.

The infographic titled “Africa’s Unprecedented Urbanization Is Reshaping Its Security Landscape”, published by the Africa Center for Strategic Studies in May 2025, visualizes the impact of rapid urban growth on security dynamics across the continent. By 2050, Africa’s urban population is projected to reach 1.4 billion. The infographic highlights how informal urban settlements are becoming increasingly vulnerable to organized crime, militant activity, gang violence, and rising social tensions. Urban centers like Khartoum, Goma, Bamako, and Maiduguri are emerging as key hotspots of insecurity. The document calls for urban security approaches that prioritize community-based policing, social services, and inclusive governance, warning against heavy-handed or exclusionary strategies that risk further alienating marginalized populations.

This Policy Brief analyzes how population displacements have accelerated urbanization in secondary cities across the Sahel, particularly in Burkina Faso, Mali, and Niger. These cities, already marked by infrastructural shortcomings, face mounting pressure on housing, land use, and basic services. The massive influx of internally displaced persons (IDPs) reshapes social dynamics, especially gender roles, with displaced women often becoming heads of households under precarious conditions. “Non-loti” areas—informal settlements—emerge as default reception zones despite lacking infrastructure. Displaced populations are sometimes viewed with suspicion and associated with security threats. The study urges moving beyond institutional categories and quantitative data, advocating for deeper exploration of “practical norms” that govern urban life. It calls for empirical research to guide inclusive urban planning and better integration of displaced communities in fragile Sahelian contexts.

In Ziguinchor, southern Senegal, urban agriculture faces challenges posed by environmental changes and population growth. This article examines, through quantitative and qualitative observations and surveys, food resilience in the face of crises such as pollution, salinity and acidification. The results indicate a degradation of agricultural and natural spaces, reflecting a vulnerability linked to urbanization and the impoverishment of ecosystems. Certain nurturing spaces, endowed with cultural or religious value, encourage their preservation. Finally, a greening of agricultural practices is respected, although these initiatives are not yet fully supported by local authorities.

The article entitled “Revealing social vulnerability profiles for the management of urban floods: the case of Ouagadougou (Burkina Faso)”, written by Mwingnè Laure Carolle Da, Hugues Hangnon, Marion Amalric, Aude Nikiema, Élodie Robert and Emmanuel Bonnet, was published in 2022 in Cybergeo: European Review of Geography. It analyzes the vulnerability of the inhabitants of Ouagadougou to flooding as part of phase 2 of the Raincell Africa project. A socio-demographic survey carried out among 2,137 households made it possible, thanks to statistical analyses, to identify eight vulnerability profiles. The results indicate that the peripheral areas of the city, characterized by informal settlements, are the most vulnerable. This increased exposure is linked to sociodemographic factors such as education level, risky urbanization behaviors and poor perception of danger. These elements are crucial for improving urban flood management.

The World Bank’s June 2022 report on the G5 Sahel (Burkina Faso, Chad, Mali, Mauritania, Niger) highlights that these economically fragile countries face challenges such as political instability, growing insecurity, uncontrolled urbanization, declining agricultural productivity, and a food crisis affecting millions of people. Climate change is exacerbating these vulnerabilities, increasing migration and social exclusion. However, the region has untapped assets, including a growing young population and renewable energy resources. Smart climate investments and strengthening policies and institutions could improve resilience to the impacts of climate change and avoid carbon-intensive growth. A stronger state presence is crucial to improve the quality of services, especially in the post-COVID context and in the face of supply chain disruptions due to the Russia-Ukraine crisis. A green and resilient Sahel requires accumulated commitment from states at all levels
