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.

Balancing the trade-offs between land productivity, labor productivity and labor intensity.

Agricultural intensification, through increased yields, and raising incomes, through enhanced labor productivity, are two dimensions prioritized for sustainable agricultural development. Prioritizing these two outcomes leaves labor intensity as a hidden adjustment variable. Yet, when agriculture is mainstay and the prospects of labor absorption in other sectors are scarce, the density of agricultural employment is central for livelihoods. We revise relationships of land and labor productivity and labor intensity with farm size, using standardized data for 32 developing countries. We show that labor productivity increases with farm size, while land productivity and labor intensity decrease with farm size nonlinearly. Technical efficiency increases with farm size. We further systematize the evidence on how, beyond the farm level, local contexts can be pivotal in choosing how to prioritize the dimensions of the trade-off space. Our findings contribute to debates on the fate of small-scale farmers, and call for contextualized decisions.

Food security and sustainability: can one exist without the other?

OBJECTIVE: To position the concept of sustainability within the context of food security. DESIGN: An overview of the interrelationships between food security and sustainability based on a non-systematic literature review and informed discussions based principally on a quasi-historical approach from meetings and reports. SETTING: International and global food security and nutrition. RESULTS: The Rome Declaration on World Food Security in 1996 defined its three basic dimensions as: availability, accessibility and utilization, with a focus on nutritional well-being. It also stressed the importance of sustainable management of natural resources and the elimination of unsustainable patterns of food consumption and production. In 2009, at the World Summit on Food Security, the concept of stability/vulnerability was added as the short-term time indicator of the ability of food systems to withstand shocks, whether natural or man-made, as part of the Five Rome Principles for Sustainable Global Food Security. More recently, intergovernmental processes have emphasized the importance of sustainability to preserve the environment, natural resources and agro-ecosystems (and thus the overlying social system), as well as the importance of food security as part of sustainability and vice versa. CONCLUSIONS: Sustainability should be considered as part of the long-term time dimension in the assessment of food security. From such a perspective the concept of sustainable diets can play a key role as a goal and a way of maintaining nutritional well-being and health, while ensuring the sustainability for future food security. Without integrating sustainability as an explicit (fifth?) dimension of food security, today's policies and programmes could become the very cause of increased food insecurity in the future.
