The current situation of global food and nutrition security is increasingly worrisome, and it is unfortunate that progress in eliminating hunger, food insecurity, and multiple forms of malnutrition has been hindered or even reversed by recent global events. It is estimated that globally, 702 million to 828 million people (8.9 to 10.5 percent) suffered from hunger in 2021, with 150 million added during the COVID-19 pandemic. Approximately 2.3 billion people are in a state of moderate or severe food insecurity, with 11.7 percent facing severe food insecurity. Nearly 3.1 billion people could not afford a healthy diet, which is an increase of 112 million from the last year. The causes of food insecurity are multifaceted, including the impact of the COVID-19 pandemic, the crisis in Ukraine,and climate change. Simultaneously, income levels have been adversely affected, and prices have risen, reducing people’s ability to purchase food and making it unaffordable. Therefore, it is imperative for governments and other stakeholders to act collectively to improve the state of global food and nutritional health. Many countries, including China, have begun to pay more attention to the issue of agrifood systems and are proposing a transition to the multidimensional goals of nutrition and health, green and low-carbon, efficiency, resilience, and inclusiveness. At the international level, a series of high-level international conferences and action plans, such as the UN Food Systems Summit, the Nutrition for Growth Summit, and UN Climate Change Conference (COP26) in 2021 and COP27 in 2022, have demonstrated the importance and urgency of promoting the transformation of agrifood systems. These conferences advocated for countries to work together to transform the way food is produced and consumed to build healthier, sustainable, and equitable food systems. At the domestic level, China has always regarded food security as a top priority for national development. In 2022, the total annual national grain output reached 686.53 million tons and has remained stable for eight consecutive years at more than 650 million tons. In 2022, the Chinese government emphasized the need to “establish a big food concept” and “strengthen the foundation of food security in all aspects” from the perspective of putting people first and better meeting their increasingly diversified food consumption needs. In light of the various risks and challenges posed by the contemporary era, safeguarding food security necessitates a shift from a narrow focus on food production to a more comprehensive consideration of the entire food supply chain. This entails promoting the development of a diversified food supply system and expanding the focus from mere quantity to encompassing multiple objectives related to the “quantity, structure, and quality” of food. Such an approach will serve to bolster the foundations of food security on all fronts.

Recurrent food crises and climate change, along with habitat loss and pollution, have put food security and environmental sustainability at the top of the political agenda. Analyses of the dynamic linkages between food consumption patterns and environmental concerns have recently received considerable attention from the international and scientific community. Using the lens of a wide sustainability concept, this paper aims at developing a multidimensional framework for evaluating sustainability in food systems and diets applicable to the Mediterranean countries. The Mediterranean region - a geographically interlocked and heterogeneous area including South European, North African and South-East Mediterranean Countries – presents several conditions of vulnerability to food insecurity and unsustainability. Furthermore the demographic growth, in urban and coastal areas of the Basin, leads to an increasing pressure on natural resources and widening disequilibria with rural areas. Derived from natural disaster and sustainability sciences, a coupled domain/vulnerability approach has been applied to the analysis of the concepts of sustainable food security and diets. Within consensus-based preselected domains, the vulnerability methodology offers a coherent framework that disentangles exposure, sensitivity and adaptive capacities. A DELPHI method is applied to select the final set of indicators from the literature. The main result is the elaboration of an innovative conceptual evaluation framework for measuring sustainability in the agrofood system. The framework draws upon two existing approaches: a vulnerability-based assessment method combined with an analysis of detailed empirical domains relevant for Mediterranean countries. The DELPHI selection process, involving several international experts, has reduced the number of indicators to a reduced pool of indicators. Use of the participatory approach of the DELPHI method helps move beyond subjective evaluation and reach consensus. Recognizing the systemic dimension of sustainability, the vulnerability approach enables to investigate the causal factors dynamics, instead of targeting exclusively the final outcomes. The domain-based framework reflects the region- specific attributes that necessarily need to be identified to link scientific concepts with metrics. Urbanisation is a main domain of vulnerability as it is a key driver of change affecting both market dynamics and consumers’ behaviours, raising questions for food security.

The first case of COVID-19 in Uganda was reported on March 22, 2020. The number of COVID-19 cases remained low during the first three quarters of 2020, before a first spike toward the end of the year. To understand the gendered impacts of the pandemic, phone surveys with rural women and men in Uganda were conducted. Data were collected from a sub-set of households drawn from a survey conducted in 2017 in 8 districts of the country: Iganga, Kasese, Kiboga, Luwero, Masaka, Masindi, Mbale, and Mubende. Four rounds of phone surveys were conducted in October 2020, February 2021, April 2021, and June 2021. The surveys focused on the economic impact, coping strategies, impact on food security and dietary diversity and the impact on children’s education and care burden. This brief presents the findings.
