The COVID-19 coronavirus outbreak has affected populations across the world. In a short time we were exposed to a critical situation, faced with numerous medical, social and economic challenges. While the medical community has focused on developing successful diagnostic and medical treatments, many countries.

The current international scenario with the war in Ukraine will have potential impacts on agri-food systems across the world. This scenario will change the balance of power among actors in the agri-food sector. High margins of uncertainty are common across supply chains in the face of uncontrolled increases in raw material prices and an uncertain guarantee of supply. This uncertainty is compounded by rising energy prices, putting the entire agrifood supply chain, which is highly energy-intensive, in crisis. In addition, the current war scenario could impact the demand for agricultural and food products by changing consumers' purchasing habits. Increasing the resilience of agri-food systems may need to become a priority for many national economic systems. In this scenario, the routes to achieve resilient agrifood systems are numerous and include reducing agriculture's dependence on energy, energy-intensive imports and raw material imports. Resilience also requires diversified import sources and market outlets through sound multilateral and bilateral trade policy.

The global coronavirus pandemic is revealing major weaknesses, inequities and system-wide risks in global food systems, giving renewed urgency to foster pathways to greater food system sustainability and resilience. Due to rising unemployment, supply chain disruptions and other responses to the pandemic, such as disruptions to social assistance programs in some countries, predictions suggest a near doubling of food insecurity globally. Nutritional changes are also occurring, as food availability and access changes, leading to substitution of dry, canned or processed foods for healthier, fresh ingredients, for some communities, and the reverse for others. These food security and nutritional changes are likely to be as impactful on human health as the virus itself. As a system-wide shock, the pandemic reveals weaknesses of global supply chains. The media highlighted empty supermarket shelves alongside food dumping in situations where producers locked into disappearing food service outlets were unable to access new markets. Farmers with long-standing reliance on migrant agricultural labor that can no longer travel across international borders under lockdown struggle to access support for the upcoming harvest season. The pandemic highlights well-known inequities for marginalized food systems employees; as essential workers are exposed to greater risks of contracting the virus in food-processing, agricultural and grocery store settings, but have little choice in accepting these conditions in order to keep these low-paying jobs. The pandemic reinforces another well-known food system inequity: marginalized and impoverished minorities often suffer from diet-related diseases (i.e. cardiovascular diseases, diabetes) and/or malnutrition that place them at greater risk of morbidity and mortality from the coronavirus. Lockdowns and border closures are reducing economic opportunities such as day labor and agricultural markets in some regions, such as much of Africa; ensuing risks of food and nutrition insecurity for vast segments of the population threaten to set back development, increase social conflict, and catalyze migration. Finally, the current pandemic shines a spotlight on the systemic risk of infectious diseases to emerge and become globalized through local bushmeat markets and international wildlife trade, and how wildlife hunting and trade is influenced by land use changes, including by industrial agriculture. At the same time, adaptive responses to the coronavirus illustrate how more resilient and sustainable food systems could evolve going forward. To avoid supply chain disruptions, communities are increasing their reliance on local food systems, including an increase in urban gardening and community-supported agriculture programs. Small-scale farmers are innovating to connect with buyers and with each other, including through new online marketing initiatives. Entrepreneurs are identifying foods that would otherwise be wasted and directing them to food banks. Retailers and wholesalers are re-configuring their distribution networks to shift food to where it is needed most. Food pantries, local producers and food businesses are also collaborating with municipal governments to address food security gaps arising from COVID-19 impacts.

This paper combines pre-pandemic face-to-face survey data with follow up phone surveys collected in April-May 2020 to quantify the overall and differential impacts of COVID-19 on household food security, labor market participation and local food prices in Nigeria. We exploit spatial variation in exposure to COVID-19 related infections and lockdown measures along with temporal differences in our outcomes of interest using a difference-in-difference approach. We find that those households exposed to higher COVID-19 cases or mobility lockdowns experience a significant increase in measures of food insecurity. Examining possible transmission channels for this effect, we find that COVID-19 significantly reduces labor market participation and increases food prices. We find that impacts differ by economic activities and households. For instance, lockdown measures increased households' experience of food insecurity by 12 percentage points and reduced the probability of participation in non-farm business activities by 13 percentage points. These lockdown measures have smaller impacts on wage-related activities and farming activities. In terms of food security, households relying on non-farm businesses, poorer households, those with school-aged children, and those living in remote and conflicted-affected zones have experienced relatively larger deteriorations in food insecurity. These findings can help inform immediate and medium-term policy responses, including social protection policies aiming at ameliorating the impacts of the pandemic, as well as guide targeting strategies of governments and international donor agencies by identifying the most impacted sub-populations.

Considering the detrimental environmental impact of current food systems, and the concerns raised about their sustainability, there is an urgent need to promote diets that are healthy and have low environmental impacts. These diets also need to be socio-culturally acceptable and economically accessible for all. Acknowledging the existence of diverging views on the concepts of sustainable diets and healthy diets, countries have requested guidance from the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) on what constitutes sustainable healthy diets. These guiding principles take a holistic approach to diets; they consider international nutrition recommendations; the environmental cost of food production and consumption; and the adaptability to local social, cultural and economic contexts. This publication aims to support the efforts of countries as they work to transform food systems to deliver on sustainable healthy diets, contributing to the achievement of the SDGs at country level, especially Goals 1 (No Poverty), 2 (Zero Hunger), 3 (Good Health and Well-Being), 4 (Quality Education), 5 (Gender Equality) and 12 (Responsible Consumption and Production) and 13 (Climate Action).

Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.

Two years after the onset of the COVID-19 pandemic, the health, economic, and social disruptions caused by this global crisis continue to evolve. The impacts of the pandemic are likely to endure for years to come, with poor, marginalized, and vulnerable groups the most affected. In COVID-19 & Global Food Security: Two Years Later, the editors bring together contributions from new IFPRI research, blogs, and the CGIAR COVID-19 Hub to examine the pandemic’s effects on poverty, food security, nutrition, and health around the world. This volume presents key lessons learned on food security and food system resilience in 2020 and 2021 and assesses the effectiveness of policy responses to the crisis. Looking forward, the authors consider how the pandemic experience can inform both recovery and longer-term efforts to build more resilient food systems.
