Bio

Josée Randriamamonjy is a Senior Scientist in the Foresight and Policy Modeling Unit and has been with IFPRI since 2006. Her research topics cover the driving forces affecting the global food system, their links to agricultural production, and related policy options to better achieve the reduction of poverty, food insecurity, and malnutrition, and she is currently working on employment, youth, and rural development. Previously, she worked in the Poverty, Health, and Nutrition Division of IFPRI where her work focused on assessing the impacts of the UNICEF nutrition interventions in Ghana, and on poverty analysis in Mozambique. Prior to her work at IFPRI, she was in charge of the Modeling Service of the National Statistics Institute of Madagascar.

Measuring agrifood systems: New indicators and global estimates

Transformation of the agrifood system is a cornerstone of many governments’ national development plans. This reflects the importance of agrifood systems for the livelihoods and wellbeing of poor populations as well as the continued strong association of agricultural transformation with longer-term economic development and structural change. Agrifood transformation is also key to healthier diets and more sustainable production systems. However, adopting an agrifood system perspective is not trivial—it requires looking “beyond agriculture” when prioritizing policies and tracking outcomes by also considering upstream and downstream agrifood-related activities, such as agro-processing and food distribution. Measuring transformation therefore requires economywide data and innovative metrics. This study introduces two such metrics: AgGDP+, which captures the total value-added across the on- and off-farm sectors of the agrifood system, and AgEMP+, which reflects the employment generated across its various components. It further explains how consistent estimates of AgGDP+ and AgEMP+ were produced for 211 and 186 countries, respectively, over the period between 2000 and 2021, and demonstrates how this Agri-Food System Dashboard—a publicly available resource—can be used to monitor transformation, prioritize investments, and better understand the evolving role of agrifood systems in national economies or at regional or global scales.

Tajikistan’s agrifood system: The past performance and future opportunities and challenges

This study analyzes the past performance and future opportunities and challenges of Tajikistan’s agrifood system (AFS). The study measures the current size and structure of AFS and its historical contribution to economic growth and transformation through a data-driven exercise. A forward-looking economywide model is used to assess the effectiveness of future AFS growth (led by agricultural productivity gains in different value chains) in promoting multiple development outcomes. The findings of the study indicate that AFS transformation is an important part of Tajikistan’s economic transformation and structural change. Because of lower growth contributions from AFS’s off-farm components as well as fewer farm workers moving from primary agriculture to off-farm activities within AFS, Tajikistan’s AFS did not grow as quickly as the broader economy. Expanding off-farm activities to boost on-farm productivity growth remains a challenge for sustainable transformation of Tajikistan’s AFS. Using an economywide model, we find that there is no single value chain group that would most effectively achieve all desired development outcomes including broad economic growth, job creation, declining poverty, and improved diets. Livestock value chains, however, have the most potential to contribute to multiple development outcomes, particularly to dietary improvement, and these value chains also performed impressively during the study period. Moreover, most cattle and ruminants are owned by household farms, and their growth could contribute to broader agricultural transformation. The maize value chain also ranks high in the model-based comparison, but it seems to only modestly contribute to job creation and diet quality and had performed disappointingly during the study period. While growth in livestock and maize value chains face a series of challenges and constraints, promoting them together seems to offer an effective way to broadly achieve important development outcomes.

Impact of ongoing conflict and pathways to recovery in Sudan: Agricultural bounce-back, infrastructural investment, and social protection

Impact of ongoing conflict and pathways to recovery in Sudan: Agricultural bounce-back, infrastructural investment, and social protection

In response to the 2023 conflict in Sudan and its extensive socio-economic repercussions, this study investigates the resultant economic, poverty, and undernourishment impacts, using an economywide model for in-depth analysis at national and household levels. The study also seeks to identify effective recovery pathways that can mitigate the adverse impacts of the conflict, with a particular focus on the role of the agricultural sector. Key findings reveal significant economic contractions across all scenarios, with the GDP experiencing a reduction of up to 12% and 18% following estimates by the World Bank and the International Monetary Fund (IMF) for 2023. These estimates are included in an economywide framework, linked to a microsimulation module as major war scenarios, namely, Moderate decline & slow recovery and Sharp decline & rapid recovery, respectively. Poverty rates are projected to increase by 8 and 11.6 percentage points, affecting an additional 2.7 and 3.9 million people in the two scenarios, respectively. Undernourishment is also expected to rise significantly, with an increase of 3.9 and 6.0 percentage points, adding approximately 1.3 and 2.0 million people to those affected in the two scenarios, respectively. The analysis proposes recovery strategies that emphasize agricultural productivity, infrastructure investment, and social protection measures. By simulating enhanced agricultural productivity scenarios, the study suggests that poverty could decrease notably, with potential reductions in the poor population by as much as 1.9 million by 2028. This study underscores the urgency of coordinated policy efforts and international support to mitigate the adverse impacts of the conflict, providing a strategic roadmap for recovery initiatives aimed at sustainable development and stability in Sudan.
