TOPIC

Food Systems

Food systems are the sum of actors and interactions along the food value chain—from input supply and production of crops, livestock, fish, and other agricultural commodities to transportation, processing, retailing, wholesaling, and preparation of foods to consumption and disposal. Food systems also include the enabling policy environments and cultural norms around food. Ideal food systems would be nutrition-, health-, and safety-driven, productive and efficient (and thus able to deliver affordable food), environmentally sustainable and climate-smart, and inclusive. To realize this vision, continued investments must be made in agricultural research and development and technological innovations, paving the way for programs and policies that are based on sound evidence.

IFPRI conducts research and offers policy support on a range of food system issues from farm-level productivity to development of inclusive food value chains to nutrition education—providing evidence for design of food systems that provide people with equitable access to nutritious, sustainable diets and contribute to more broadly to development and well-being.

IFPRI’s research on this topic is closely aligned with the Sustainable Development Goals (SDGs), including SDG 1, SDG 2, SDG 12, SDG 14, and SDG 15.

A multi-sectoral community development intervention has a positive impact on diet quality and growth in school-age children in rural Nepal

A multi-sectoral community development intervention has a positive impact on diet quality and growth in school-age children in rural Nepal

Poor diet quality (diet diversity and animal-source food [ASF] consumption) during childhood negatively affects growth, development, behaviour and physiologic function in later life. Relatively less is known about the impact of poor diet on the growth of school-age children compared to children <5 years of age, especially in low/middle-income countries. A better understanding of delivery strategies for effective interventions to improve diet and hence growth in school-age children is needed. A 36-month longitudinal controlled impact evaluation in rural Nepal assessed the nutrition and growth of children <5 years of age in families assigned via community clusters to full package intervention (community development, training in nutrition [during pregnancy and for children <5 years] and livestock husbandry), partial package (training only) or control (no inputs). Concurrent data were collected prospectively (baseline plus additional four rounds) on school-age children (5–8 years at baseline) in these households; the present study analysed findings in the cohort of school-age children seen at all five study visits (n = 341). Diet quality improved more in the full package school-age children compared to those in partial package or control households. full package children consumed more ASF (β +0.40 [CI 0.07,0.73], p < 0.05), more diverse diets (β +0.93 [CI 0.55,1.31], p < 0.001) and had better head circumference z-scores (β +0.21 [CI 0.07,0.35], p < 0.01) than control children. In conclusion, a multi-sectoral community development intervention was associated with improvements in diet and growth of school-age children in rural Nepal even though the intervention focused on the diet of children <5 years of age. The diet and growth of school-age children can be favourably influenced by community-level interventions, even indirectly.

The true costs of food in Kenya and Vietnam: A conceptual framework

The true costs of food in Kenya and Vietnam: A conceptual framework

Sustainable food systems provide enough quality, healthy, and affordable food to all without imposing a burden on planetary and social boundaries. By this standard, it is quite clear that food systems in many countries are not sustainable as they generate substantial environmental, social, and health costs while failing to provide affordable food to all (FAO et al., 2020). This implies the need to have a good understanding of the extent to which those externalities are present in country specific food systems. The key challenge is that such externalities are not reflected in market prices (Baker et al., 2020), being therefore hidden factors to drivers of choices by market players, as the link between market activity and those social and environmental harms is not directly visible or reflected in the incentives that drive economic systems (UNFSS, 2021). Internalizing the externalities of the food systems will require the full estimation of costs, including the measurement of externalities through “True Cost Accounting” (TCA) approaches. This document provides the analytical framework for the application of approaches in a research study to measure the true costs of food in Kenya and Vietnam. It focuses on: o Key research questions, their relevance, and policy implications o How the TCA analytical framework fits in The Economics of Ecosystems and Biodiversity (TEEB) framework o Country selection and geographic focus – national, sub-national o Data requirements for estimating the true costs, including household surveys, workers’ surveys, externally compiled Global Impact Database (GID), and monetization factors. o A step-by-step process for estimating the true costs in the study area and country level GID analysis.

Impacts of Africa RISING in Ghana

Impacts of Africa RISING in Ghana

Sustainable intensification (SI) of the smallholder sector in Africa south of the Sahara is among the approaches pursued to build resilient food systems that can supply nutritionally adequate food in the face of rapid population growth and climatic changes. This study assesses the impact of Africa RISING, an SI program in Ghana implemented in the poorest and most food insecure areas of the country since 2012. The program first validated and then scaled up a wide range of SI interventions focused on improved agronomic management and crop cultivars; improved livestock feed, housing conditions, and species; crop-livestock integration; integrated natural resource management; vegetable production and nutritional education; and small-scale mechanization. Impact is estimated using two rounds of quasi-experimental panel data (conducted in 2014 and 2020), propensity score matching, and difference-indifferences techniques. The study design allows us to estimate the impact of Africa RISING by comparing outcomes among program beneficiaries with those of two different control groups—one residing in program villages (within village comparison) and another in non-program (control) villages (out-of-village comparison) on several indicators across five SI domains—environment, productivity, economic, human, and social. We also conduct a placebo test comparing non-beneficiaries in the two control groups. Results from panel data analyses show improvements in several indicators in the environmental and productivity domains. We also find a positive impact on use of conservation practices (fallowing, disc/moldboard ploughing, manure), groundnut yield, livestock, net crop income, and women’s likelihood of becoming members of farmers groups relative to non-beneficiaries. We do not find a statistically significant effect on consumption- and asset-based poverty rates, household dietary diversity, and several indicators of maternal and child nutrition. For both beneficiaries and non-beneficiaries, the share of monetary-based non-poor, dietary diversity, and food security have declined between baseline (2014) and follow-up (2020) likely due COVID-19. Our study highlights useful empirical lessons learned for informing future program design and impact assessments.
