Convenience as a dimension of food environments: A systematic scoping review of its definition and measurement

Convenience is a major driver of food choice throughout the world, yet it is often inconsistently conceptualised, defined and measured. This limits the scope for food systems policy and interventions to leverage convenience to improve diet and nutrition outcomes. We conducted a systematic literature review to determine how convenience is both defined and measured in food environment and nutrition research. Six databases were systematically searched and studies were screened by two independent reviewers based on pre-defined eligibility criteria, yielding 243 studies for inclusion in the final review. 77% of studies did not explicitly define convenience. Among those that did, the dimensions and components within definitions varied. 83% of studies used perceived measures of convenience rather than objective measures. Convenience was most commonly measured in high income countries (64%) and in relation to the home food environment (53%), followed by formal retail (40%). Very few studies measured convenience in relation to the informal retail or cultivated food environments, and no studies considered convenience in relation to wild food environments. The vast majority of studies did not consider the validity or reliability of the measures of convenience. Based on our findings we propose a definition of convenience as a characteristic that results in reduced requirement for resources including time, physical effort, mental effort and skills by the consumer in relation to the planning, acquisition, preparation, storage, transport, consumption or clean-up of food. This definition can be used to help guide the development of measurement tools that can be used to assess convenience across different dimensions and contexts in a more comprehensive way. We also propose a framework for considering convenience as an entry point in food systems to improve diets and nutrition outcomes.

The state of food systems worldwide in the countdown to 2030

This Analysis presents a recently developed food system indicator framework and holistic monitoring architecture to track food system transformation towards global development, health and sustainability goals. Five themes are considered: (1) diets, nutrition and health; (2) environment, natural resources and production; (3) livelihoods, poverty and equity; (4) governance; and (5) resilience. Each theme is divided into three to five indicator domains, and indicators were selected to reflect each domain through a consultative process. In total, 50 indicators were selected, with at least one indicator available for every domain. Harmonized data of these 50 indicators provide a baseline assessment of the world's food systems. We show that every country can claim positive outcomes in some parts of food systems, but none are among the highest ranked across all domains. Furthermore, some indicators are independent of national income, and each highlights a specific aspiration for healthy, sustainable and just food systems. The Food Systems Countdown Initiative will track food systems annually to 2030, amending the framework as new indicators or better data emerge.

Riverine food environments and food security: a case study of the Mekong River, Cambodia

Rivers are critical, but often overlooked, parts of food systems. They have multiple functions that support the food security, nutrition, health and livelihoods of the communities surrounding them. However, given current unsustainable food system practices, damming and climate change, the majority of the world's largest rivers are increasingly susceptible to environmental degradation, with negative implications for the communities that rely on them. Here we describe the dynamism and multifaceted nature of rivers as food environments (i.e. the place within food systems where people obtain their food) and their role in securing food security including improved diets and overall health. We also provide a conceptual framework that explain rivers as food environments within the broader food system and describe approaches to characterizing these food environments to better inform our understanding of how they influence food security and nutrition outcomes. Applying this framework to the Mekong River in Cambodia, we describe rivers as multifaceted wild food environments embedded within ecosystems, sociocultural and political environments and sectors of influence. We also explain the ways in which individual factors might influence how communities interact with this food environment. Developing and articulating food-related, ecosystem-specific frameworks and their constructs can guide implementation of policies aimed to improve specific public health or environmental sustainability outcomes. Our conceptual framework incorporates the multiple dimensions of rivers, which will aid future work and public health policy framing to better describe, understand and intervene to ensure protection of rivers' biodiversity and ecosystems as well as food security, health and livelihoods.
