As a conflict between two major agricultural powers, the Russia–Ukraine war has various negative socioeconomic impacts that are now being felt internationally and might worsen, notably, for global food security. If the war deepens, the food crisis will worsen, posing a challenge to many countries, especially those that rely on food imports, such as those in the Middle East and North Africa (MENA) region. Simultaneously, the war came at a bad time for global food markets because food prices were already high due to disruptions in the supply chain caused by the COVID-19 pandemic, strong global demand, and poor harvests in some countries. Understanding how conflict-related disruptions in global food and fertilizer markets might affect price and availability is critical for understanding the overall impact on global food security. Further, four months into the war, its implications for food security suggest that this review is timely, urgent, and highly needed. Accordingly, this paper aims to investigate the Russia–Ukraine war’s direct and indirect impact on global food security. The paper highlights that the war resulted in immediate and far-reaching cascading consequences on global food security: Ukrainian exports have stopped, conscription and population displacement have caused labor shortages, access to fertilizers is restricted, and future harvests are uncertain. First, Ukraine’s export capacity has been hampered. Secondly, conscription and population displacement caused labor shortages. Thirdly, access to vital agricultural products such as fertilizers is also constrained. The war may delay spring planting and winter crop harvesting. Further, the war has indirect and cascading effects. Indeed, rising fertilizer costs may reduce their use and crop yields. Moreover, as seen during the 2007–2008 food crisis, export restrictions and speculation are driving up international prices and worsening the situation. Furthermore, the war triggered a panic buying movement at country and individual levels. Finally, the war may jeopardize the implementation of the Sustainable Development Goals (SDGs), notably SDG 1 (No poverty), SDG 2 (Zero hunger), and DG 12 (Responsible consumption and production). However, the consequences of the war on food security are being exacerbated by a variety of underlying rigidities, vulnerabilities, and inefficiencies in global food systems. Accordingly, the transition toward healthy, equitable, and ecologically sustainable food systems must be strengthened by adopting urgent and long-term reforms and policies.

The concepts of food security and food sustainability are two main paradigms in the food system discourse—however, they are often addressed separately in the scientific literature. We argue that this disconnect hinders a coherent discussion of sustainability transitions, which will be necessary to solve problems (environmental, social, economic, and health) generated by conventional food systems. Our review highlights linkages between sustainability transitions and food and nutrition security using the perspective of sustainable food systems. We explore the diversity of food security narratives and food sustainability paradigms in the agro‐food arena, analyze relations between food security and food systems sustainability, and suggest options to foster a transition toward sustainable food systems. It is widely acknowledged that food systems sustainability must entail long‐term food and nutrition security in its availability, access, utilization, and stability dimensions. For food systems to deliver food and nutrition security for present and future generations, all their components need to be sustainable, resilient, and efficient. These linkages between food sustainability and food and nutrition security intersect at global, national, local, and household levels. Different strategies can be pursued to foster sustainability transitions in food systems: efficiency increase (e.g., sustainable intensification), demand restraint (e.g., sustainable diets), and food systems transformation (e.g., alternative food systems). Creating sustainable food systems requires moving from an agriculture‐centered to a food system policy and research framework. This will be fundamental to foster the complex and holistic transformation necessary to achieve sustainable food systems, which is, in turn, a prerequisite to achieving sustainable food and nutrition security.

The government of Qatar took strong containment measures to prevent the spread of COVID-19 with restrictions on daily living such as social distancing and the closing of businesses and schools. While these measures are essential to stop the virus spreading, several voices came to warn of their potential disruptive impact on the agri-food system. Therefore, this paper investigates the immediate impacts of COVID-19 on Qatari consumer awareness, attitudes, and behaviors related to food consumption. The study is based on an online survey in Qatar using a structured questionnaire that was administered in the Arabic language through the Survey Monkey platform from 24 May until 14 June 2020. The results reveal clear changes in the way consumers are eating, shopping, and interacting with food. Indeed, the survey results suggested (i) a shift toward healthier diets; (ii) an increase in the consumption of domestic products due to food safety concerns; (iii) a change in the modality of acquiring food (with a surge in online grocery shopping); (iv) an increase in culinary capabilities; and (v) the absence of panic buying and food stockpiling in Qatar. The results are expected to inform current emergency plans as well as long-term food-related strategies in Qatar.

The multi-level perspective (MLP) is a prominent transition framework. The MLP posits that transitions come about through interaction processes within and among three analytical levels: niches, socio-technical regimes and a socio-technical landscape. This systematic review provides an overview on the use of the MLP in research on agro-food sustainability transitions. In particular, it analyses the understanding, conceptualisation and operationalisation of niches, regimes and landscapes. Niches considered in the selected papers include agro-ecology, organic agriculture, permaculture, conservation agriculture, integrated farming, and alternative food networks. Regime refers to industrial, conventional agriculture. The researched regime is often not clearly described and its operationalisation is a matter of deliberation. Landscape level is generally overlooked; when it is considered it refers to international trends and developments. Many scholars highlight the inadequacy of transition pathways in the MLP for the agro-food sector. Moreover, transition impacts are rarely addressed and the research field generally overlooks the analysis of the sustainability of niches and, consequently, of transitions. Research on transitions in the agro-food sector borrows from the MLP its generalizability and poor empirical operationalisation of niche, regime and landscape concepts. Therefore, integrative conceptualisation and operationalisation of the MLP elements is required to accommodate the complexity of sustainability transition processes and the peculiarities of the agro-food system.

In recent decades, the confluence of different global and domestic drivers has led to progressive and unpredictable changes in the functioning and structure of agri-food markets worldwide. Given the unsustainability of the current agri-food production, processing, distribution and consumption patterns, and the inadequate governance of the whole food system, the transition to sustainable agriculture and food systems has become crucial to effectively manage a global agri-food market able in supporting expected population growth and ensuring universal access to sufficient, safe, and nutritious food for all. Based on a critical review of the existing international literature, the paper seeks to understand the evolutionary paths of sustainability issues within agri-food markets by analyzing their drivers and trends. An extensive analysis was conducted highlighting the development and importance of the body of knowledge on the most important sustainability transition frameworks, focusing mainly on the relationship between markets, trade, food and nutrition security, and other emerging issues within agri-food markets. Finally, the study makes suggestions to extend the research in order to improve basic knowledge and to identify opportunities to design meaningful actions that can shape agri-food markets and foster their transition to sustainability.
