Development Strategies and Governance

Aboubacar Hema

Research Analyst

Bio

Aboubacar Hema is a Research Analyst in the Development Strategies and Governance Unit. He is a data scientist, statistician, and software developer. Prior to joining IFPRI, Aboubacar worked as a data analyst with the International Organization for Migration (IOM), where he successfully implemented and analyzed the MHPSS surveys (round 1-3) as well as the endline surveys for Senegal, Guinea, Nigeria, and Gambia. He also worked as a statistician with the Senegalese Institute for Agricultural Research (ISRA-BAME), as well as with the Consortium for Economic and Social Research (CRES), where he was involved in the design, implementation, and analysis of various household surveys, and as an R developer (sdmApp package) with the French Agricultural Research Center for International Development (CIRAD).

Aboubacar earned a MicroMaster in Statistics and Data Science at MIT, where he learned the foundations of data science, statistics, and machine learning, using big data and probabilistic modelling to extract meaningful information for decision-making. He graduated from the National School of Statistics and Economic Analysis in Dakar and has a license 3 in Computer Science from the University of Ouagadougou, Burkina Faso.

Unique datasets on shocks, food security, and household coping strategies: Creating new analytical playgrounds to study coping behavior in the multi-shock environments of Mali, Chad, Niger, and Burkina Faso (2018-2023)

To inform the Cadre Harmonisé process in West Africa, large-scale national household surveys are usually implemented twice a year to capture data on household food security and several forms of consumption- and livelihood-based coping strategies. These cross-sectional surveys typically take place around February-March (before the start of the lean season) and September-October (at the end of the lean season or beginning of the harvesting period), and they are generally representative at the second-tier administrative level. Despite their different names (that is, ENSAN in Mali, ENSA in Chad, EVIAM in Niger, and ENISAN in Burkina Faso) and the methodological revisions introduced over the years, these surveys have a large common set of variables that were pooled together by standardizing the modalities of all common variables found across the multiple survey waves between 2018 and 2023. Apart from reconsolidation and reprocessing of initial data files, this process also involved the re-computation of several key indicators on food security and household coping as to assure maximum methodological consistency over time.

How did households in Mali cope with covariate shocks between 2018 and 2023? Exploration of a unique dataset

How did households in Mali cope with covariate shocks between 2018 and 2023? Exploration of a unique dataset

The objective of this analysis is to gain more insight into the coping behavior of households in Mali when facing covariate shocks and stressors of different kinds. To achieve this, we rely on a unique dataset, which consists of eleven waves of cross-sectional household data combined with an extensive list of shock indicators compiled from external sources. Apart from a detailed profiling of both dimensions, this analysis relies on a data mining algorithm to uncover interesting associations between covariate shocks and coping strategies. Among the main findings of this study is the pronounced diversity in shock and coping profiles observed across time and place, which in turn complicates any straightforward identification of common and consistent patterns in household coping behavior. This said, political violence has increased over time; food prices hiked in 2018, 2022 and 2023; rainy seasons were underperforming in 2021 and 2023; extreme weather events reached a peak in 2021; while the Gao region in 2023 suffered from all five shock domains at the same time. While fewer households resorted to coping over time, those who did combined slightly more strategies – which either points to increased inequality or generalized depletion of coping potential. Further, poor and erratic weather conditions appear to be important triggers for households to disinvest in farming and livestock activities, with food secure people being more inclined to resort to emergency coping when shocks prevail. This analysis also very much reveals the need for additional research on the same integrated and enhanced dataset.

Among the main findings of this study is the pronounced diversity in shock and coping profiles observed across time and place, which in turn complicates any straightforward identification of common and consistent patterns in household coping behavior. This said, political violence has increased until 2022 and then fell back; food prices hiked in 2022 and 2023; rainy seasons were underperforming in 2021 and 2023; extreme weather events reached a peak in 2022; while four departments in 2023 suffered from four distinct shock domains at the same time. While coping prevalence and coping intensity are roughly aligned over time, they are only weakly correlated in geographical terms in 2023. Further, the biggest change in people’s coping behavior involves keeping children from school when confronted with severe political violence coupled with severe climate change and light seasonal performance shocks – while many distinct combinations apply for different subpopulations. Finally, this analysis also very much reveals the need for additional research on the same integrated and enhanced dataset.
