Resilience of local food systems and links to food security - A review of some important concepts in the context of COVID-19 and other shocks.

Abstract: The objective of this review is to explore and discuss the concept of local food system resilience in light of the disruptions brought to those systems by the 2020 COVID-19 pandemic. The discussion, which focuses on low and middle income countries, considers also the other shocks and stressors that generally affect local food systems and their actors in those countries (weather-related, economic, political or social disturbances). The review of existing (mainly grey or media-based) accounts on COVID-19 suggests that, with the exception of those who lost members of their family to the virus, as per June 2020 the main impact of the pandemic derives mainly from the lockdown and mobility restrictions imposed by national/local governments, and the consequence that the subsequent loss of income and purchasing power has on people's food security, in particular the poor. The paper then uses the most prominent advances made recently in the literature on household resilience in the context of food security and humanitarian crises to identify a series of lessons that can be used to improve our understanding of food system resilience and its link to food security in the context of the COVID-19 crisis and other shocks. Those lessons include principles about the measurement of food system resilience and suggestions about the types of interventions that could potentially strengthen the abilities of actors (including policy makers) to respond more appropriately to adverse events affecting food systems in the future.

Conceptualising COVID-19's impacts on household food security.

Abstract: COVID-19 undermines food security both directly, by disrupting food systems, and indirectly, through the impacts of lockdowns on household incomes and physical access to food. COVID-19 and responses to the pandemic could undermine food production, processing and marketing, but the most concerning impacts are on the demand-side - economic and physical access to food. This paper identifies three complementary frameworks that can contribute to understanding these effects, which are expected to persist into the post-pandemic phase, after lockdowns are lifted. FAO's 'four pillars'- availability, access, stability and utilisation - and the 'food systems' approach both provide holistic frameworks for analysing food security. Sen's 'entitlement' approach is useful for disaggregating demand-side effects on household production-, labour-, trade- and transfer-based entitlements to food. Drawing on the strengths of each of these frameworks can enhance the understanding of the pandemic's impacts on food security, while also pinpointing areas for governments and other actors to intervene in the food system, to protect the food security of households left vulnerable by COVID-19 and public responses.

Global drivers of food system (un)sustainability: A multi-country correlation analysis

Abstract: At present, our ability to comprehend the dynamics of food systems and the consequences of their rapid 'transformations' is limited. In this paper, we propose to address this gap by exploring the interactions between the sustainability of food systems and a set of key drivers at the global scale. For this we compile a metric of 12 key drivers of food system from a globally-representative set of low, middle, and high-income countries and analyze the relationships between these drivers and a composite index that integrates the four key dimensions of food system sustainability, namely: food security & nutrition, environment, social, and economic dimensions. The two metrics highlight the important data gap that characterizes national systems' statistics-in particular in relation to transformation, transport, retail and distribution. Spearman correlations and Principal Component Analysis are then used to explore associations between levels of sustainability and drivers. With the exception of one economic driver (trade flows in merchandise and services), the majority of the statistically significant correlations found between food system sustainability and drivers appear to be negative. The fact that most of these negative drivers are closely related to the global demographic transition that is currently affecting the world population highlights the magnitude of the challenges ahead. This analysis is the first one that provides quantitative evidence at the global scale about correlations between the four dimensions of sustainability of our food systems and specific drivers.

Changing diets and the transformation of the global food system.

Abstract: An aspirational global food system is one that delivers across a suite of the Sustainable Development Goals (SDGs), including universal access to healthy diets, which can also codeliver on climate and environment SDGs. The literature has downplayed the relative contribution of dietary change to sustainable food systems. In this perspective article, we argue that the potential for positive transformational change in diets should not be underestimated, for two sets of reasons. First, the dynamism of diets over long-term and, especially, recent history shows the potential for rapid and widespread change, including toward more diverse and healthier diets. Second, contemporary behavioral research demonstrates promising tactics to influence consumers' dietary choices. Since the entire food system creates the circumstances of those choices, the most effective strategies to shift diets will involve multiple approaches that deliberately aim not just to influence consumers themselves but also to incentivize all actors in the food systems, taking into account multiple agendas and values. The effectiveness of actions will depend on the political economy at local, national, and global levels. Overall, there are reasons to be hopeful about the potential for accelerated global dietary change, given both historic trends and the growing suite of tools and approaches available.

Five priorities to operationalize the EAT–Lancet Commission report

Abstract: To operationalize the great food system transformation and ensure its sustainability, five areas of research and action require more attention: economic and structural costs; political economy; diversity of cultural norms; equity and social justice; and governance and decision support tools.

Impacts of resilience interventions – Evidence from a quasi-experimental assessment in Niger

Abstract: In this paper we aim to evaluate the effects of a 3-year resilience intervention (the SUR1M project in Niger) on the beneficiaries of the project. The evaluation was structured around the project's theory of change and designed to evaluate three elements along that theory of change: the types of responses beneficiaries adopt when faced with adverse events; their ability to recover from those events; and the long-term impact on their well-being, measured through their level of food (in)security. Using a quasi-experimental approach and an ex-post treatment versus control framework we found significant effects of the project on beneficiaries' capacities to engage in (positive) responses and on their abilities to recover from shocks. The analysis did not find however any significant difference between the well-being of the beneficiaries and that of the control group, suggesting that, after three years, the higher level of resilience of the beneficiaries did not translate into a clear positive impact on their well-being.

Metrics to analyze and improve diets through food Systems in low and Middle Income Countries

Abstract: Taking a food systems approach is a promising strategy for improving diets. Implementing such an approach would require the use of a comprehensive set of metrics to characterize food systems, set meaningful goals, track food system performance, and evaluate the impacts of food system interventions. Food system metrics are also useful to structure debates and communicate to policy makers and the general public. This paper provides an updated analytical framework of food systems and uses this to identify systematically relevant metrics and indicators based on data availability in low and middle income countries. We conclude that public data are relatively well available for food system drivers and outcomes, but not for all of the food system activities. With only minor additional investments, existing surveys could be extended to cover a large part of the required additional data. For some indicators, however, targeted data collection efforts are needed. As the list of indicators partly overlaps with the indicators for the Sustainable Development Goals (SGDs), part of the collected data could serve not only to describe and monitor food systems, but also to track progress towards attaining the SDGs.

Child Overweight or Obesity Is Associated with Modifiable and Geographic Factors in Vietnam: Implications for Program Design and Targeting

Abstract: Child overweight or obesity is increasing in most countries, including Vietnam. We sought to elucidate the drivers of child overweight or obesity in Vietnam and understand how they vary geographically. We compiled nationally representative cross-sectional data from the Vietnam Nutrition Surveillance Survey collected annually between 2012-2015 and household income data from the General Statistics Office. We used a quasi-Poisson log link function to calculate relative risks (RRs) of under-five child overweight or obesity for 13 variables and stratified analyses by child age ( 4000 g (RR: 1.66; 95% confidence interval (CI): 1.48, 1.86), maternal body mass index (BMI) ≥27.5 compared with BMI <23 (RR: 1.62; 95% CI: 1.47, 1.78), and living in the Southeast (RR: 2.06; 95% CI: 1.84, 2.30), Mekong River Delta (RR: 1.58; 95% CI: 1.41, 1.77), or Central South (RR: 1.54; 95% CI: 1.37, 1.74) compared with the Central Highland. A 20% higher provincial average monthly per capita income was associated with a 17.4% higher prevalence in child overweight or obesity (P < 0.0001, Adjusted R2 = 0.36). High birthweight and maternal BMI were strongly associated with child overweight or obesity but are not likely primary drivers in Vietnam, given their low prevalence. C-section delivery, sedentary lifestyle, high maternal education, urbanicity, and high household income affect a large proportion of the population and are, therefore, important risk factors. Policies and programs should target these factors and regions at greatest risk of overweight or obesity, particularly the Southeast and Mekong River Delta.

Are we messing with people's resilience? Analysing the impact of external interventions on community intrinsic resilience

Abstract: People are by nature characterized by some degree of intrinsic resilience. The capacity of households and communities to deal with shocks and stressors (their resilience) is therefore not something that is simply “introduced” or “added” externally through the activities of a project, but instead something that exists internally, and that can be altered (strengthened or weakened) by external interventions. Using qualitative data from a resilience programme in Burkina Faso, we propose to explore more thoroughly the question of the dynamics between community intrinsic resilience and external interventions. For this, several related issues are investigated, including the possibility of erosion of intrinsic resilience mechanisms due to the effect of recurrent shocks, the potential crowding-out effect of external interventions on those intrinsic resilience mechanisms, and the exploration of detailed causal pathways describing the ways external interventions can create additional elements of resilience amongst the targeted communities. Some of the programmatic and research implications of the key-findings are highlighted.
