Determinants of household water and energy access and their impacts on food security and health outcomes in Sudan

Determinants of household water and energy access and their impacts on food security and health outcomes in Sudan

This study investigates the determinants of access to safe water and reliable energy for households in Sudan using nationally representative data from a recent labor market survey. The results show that urbanization, education, and wealth significantly enhance the access households have to these essential services, while rural areas and less developed regions, particularly in the Darfur and Kordofan regions, face substantial challenges. Access to reliable energy correlates with better food security and health outcomes within households, and improved access to safe water significantly enhances the health of household members. Policy recommendations supported by these research results include targeted rural infrastructure investments, educational improvements, and regional interventions to address disparities in household access to safe water and reliable energy across Sudan.

Under the gun: Military and paramilitary actors in Sudan’s agri-food system

Under the gun: Military and paramilitary actors in Sudan’s agri-food system

Armed actors, including militaries and paramilitaries, are heavily entrenched in the agrifood systems of several low- and middle-income countries, often resulting in negative implications for both agricultural transformation and democratic transitions. However, the role of armed actors is overlooked in the scholarship on the governance of agricultural value chains. To address this gap, this paper focuses on the role of the Sudanese Armed Forces (SAF) and Rapid Support Forces (RSF) in Sudan’s agrifood system. Through over 50 semi-structured interviews with key stakeholders, the paper traces how the SAF and RSF initially gained their foothold in the agrifood system and how they interact with each other, and the private sector across diverse value chains. We argue that these actors decide to pursue investments in certain value chains depending on the extent to which the private sector is already involved and the degree of technical complexity required to attain more profitable product upgrading. Based on these considerations, we uncover four strategies used by SAF and RSF in different value chains: exclusive capture and rent extraction, competition through biased licensing and quota allocations, acquiescence to existing private competitors when value-addition is too complex, and innovation when potential is high and the private sector is absent. We show how these strategies manifest across value chains as diverse as livestock, wheat, gum Arabic, and horticulture, with secondary applications to other commodities. Given that economic competition between SAF and RSF was a major factor in the outbreak of the 2023 armed conflict, identifying how these strategies emerged and manifested not only contributes to the literature on business-state relations but also expands insights about the political economy antecedents of large-scale conflict.

Food Systems for Healthy Diets and Nutrition: Africa Regional Launch of IFPRI’s 2024 Global Food Policy Report

Despite significant progress in addressing hunger and undernutrition in the early 2000s, malnutrition, in all its forms, remains a major challenge in all regions of the world. Unhealthy diets remain the primary drivers of many forms of malnutrition, including undernutrition, overweight and obesity, micronutrient deficiencies, and diet-related noncommunicable diseases. Today, the number of people who […]

The Socio-Economic Impact of Armed Conflict on Sudanese Urban Households

The ongoing conflict in Sudan has been concentrated in cities, with major impacts on urban households. Large numbers of families are displaced, employment is down dramatically, and most children are unable to go to school. A comprehensive survey conducted earlier this year by IFPRI’ Sudan Strategy Support Program and the United Nations Development Programme provides […]
