Bio

Wim Marivoet is Research Fellow in the Development Strategies and Governance Unit, based in Leuven, Belgium. His main research interests involve poverty measurement, spatial typologies, food systems, and food and nutrition security, with a focus on several African countries, particularly the Democratic Republic of the Congo (DRC) and Senegal.

Wim currently analyzes household coping strategies and resilience in the Sahel region. In Senegal, he is involved in strengthening national capacities and improving policies through research on food systems, climate change, gender, and nutrition.

Before joining IFPRI in 2015, Wim worked as a postdoctoral fellow at the Institute of Development Policy (IOB-University of Antwerp, Belgium), where he obtained his PhD in applied economics.

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.

The objective of this analysis is to gain more insight into the coping behavior of households in Chad 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 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.

Report

Integrated and enhanced datasets on food security and household coping strategies in the G5 Sahel Countries (2018-2023)

2024Marivoet, Wim; Hema, Aboubacar
Details

Integrated and enhanced datasets on food security and household coping strategies in the G5 Sahel Countries (2018-2023)

This report describes the methodology and output behind the integration and enhancement of nationally representative household surveys on food security and coping strategies implemented in the G5 Sahel countries between 2018 and 2023. Whereas the data integration process involves the harmonization of variables across multiple cross-sectional surveys, the enhancement procedure focuses on adding shock data on multiple dimensions of political violence, food price anomalies, and climate- and weather-related events. Despite shortcomings in data quality and exhaustivity, the resulting datasets represent a unique playground to study the interaction between shocks and stressors on the one hand and household coping strategies and their impact on food security on the other hand.

Who benefited from the Congo’s peace dividend?

By Wim Marivoet, Tom De Herdt, and John Ulimwengu

New research suggests the Democratic Republic of the Congo missed an important opportunity to combat its devastating poverty.

Understanding Urban and Rural Household Food Consumption in Senegal

Using household consumption data collected in 2017/18, this chapter analyzes patterns of urban and rural food consumption in Senegal. We adopt two methodological approaches. The first is an in-depth (spatial) analysis of current diets and corresponding nutrient deficiencies, coupled with an identification of possible food items to address existing nutrient gaps. The second approach is […]
