Intensified monogastric livestock management could conserve feed inputs and mitigate some of the environmental and climate challenges associated with animal production. In this study, we used data from 166 countries to model the environmental, climate and economic impacts of pig and chicken intensification. We found that whole-chain intensification could reduce annual nitrogen and greenhouse gas emissions by 49% (4.6 Tg) and 68% (554 Tg CO2-equivalent), respectively. These changes translate to 5.0 Tg lower nitrogen fertilizer input for feed production, resulting in an overall benefit of US$93 billion. Integrated crop–livestock optimization under intensive management could release 27 Mha of cropland and provide additional food for 310 million people. A judicious promotion of intensification could alleviate global pressures related to food security, environment and climate change. A scenario analysis demonstrates that integrated crop–livestock optimization combined with intensive monogastric livestock production could reduce greenhouse gas emissions and redirect cropland use from feed to food production.

More than 1,600 multi-stakeholder dialogues were convened in preparation for the United Nations Food Systems Summit 2021. These dialogues have helped facilitate inclusive explorations of the complex challenges of transforming food systems and accelerate progress towards the 2030 Sustainable Development Goals.

Potassium (K) has received little attention as a potential yield-limiting factor in cropping systems. Here we investigated the K status in intensive cereal cropping systems in Indonesia, which are representative of many other Southeast Asian countries. Our analysis included nutrient input–output balance, leaf nutrient status, long- and short-term fertilizer trials, and farmer surveys. We revealed that soil K levels alone are insufficient to meet plant requirements, and current fertilizer applications are inadequate to prevent K deficiencies and large negative annual soil K balances in farmer fields (average −62 kgK ha−1). On-farm fertilizer trials indicated that nearly 80% of rice crops and 70% of maize crops achieved higher yields with the application of K fertilizer. Addressing K limitations will require an enhanced capacity to predict crop responses to K fertilizer, together with long-term, flexible fertilizer and crop residue management strategies. Furthermore, similar K limitations have probably emerged in other regions globally due to intensive cropping with insufficient K replenishment, which must be addressed to close yield gaps on existing farmland. Future yield improvements will require a closer examination of specific production factors and their interactions. This study quantifies potassium (K) limitations in Indonesia’s intensive cereal cropping systems and reveals that current soil K levels and fertilizer applications are inadequate to meet crop needs, exacerbating the existing yield gap in rice–maize systems in Indonesia and other countries in Southeast Asia.

Techno-economic analyses offer insights into how industrial cultivated meat (CM) production could achieve price parity with conventional meat. These analyses use scaling practices, data and facility designs for related bioprocessing fields, including large (≥20,000 l) stirred tank bioreactors and suspension-tolerant, continuously available cell lines. This approach is inconsistent with most primary CM literature, which parallels bench-scale tissue engineering. TEAs published to date demonstrate that, under the current technological paradigm, CM is unlikely to be competitive with conventional meat. Scale-up feasibility may hinge on cost-saving areas such as use of plant-based media components, food-grade aseptic conditions and extensive scaling of related supply chains. Research must address knowledge gaps including serum-free differentiation, new bioreactor designs and facility design before CM can become a viable alternative to animal-based meat production. Technological advancements are needed before cultivated meat can supply dietary protein at a competitive cost and with lower environmental impacts than livestock production. This Review explores how techno-economic analyses can guide research towards providing sustainable scaled-up cultivated beef production.

Efforts to address poor-quality diets have stepped up considerably in recent years, but the problem of inadequate, unhealthy, unsustainable and unequal diets persists. Here we argue that to get policies and interventions working more effectively and equitably, a fresh approach is needed—one that considers the full picture of people’s realities. People’s realities interact to shape the way people respond to and engage with policies and interventions, thereby influencing their impact, particularly, albeit not only, on dietary inequalities. We propose a tool that brings together key realities that shape impact, including the material, economic and psychosocial realities that people face in their households, families, food environments, social interactions and cultures. The purpose of the tool is to help policymakers, intervention practitioners and researchers committed to improving diets achieve greater success by helping them think through the full picture of people’s realities when identifying, designing, implementing and evaluating policies and interventions. Engaging with people’s realities is key to the success of policies and interventions aimed at achieving better diets for all. Drawing on social practice theory, this Perspective proposes a tool—the full picture—to help researchers, practitioners and policymakers think through the full range of people’s interacting realities that shape the impact of policies and interventions designed to improve diets.

Metal(loid) contaminants in food pose a global health concern. This study offers a global analysis of the impact of nanomaterials (NMs) on crop responses to metal(loid) stresses. Our findings reveal that NMs have a positive effect on the biomass production of staple crops (22.8%), while showing inhibitory effects on metal(loid) accumulation in plants (−38.3%) and oxidative damage (−21.6%) under metal(loid) stress conditions. These effects are influenced by various factors such as NM dose, exposure duration, size and composition. Here we introduce a method using interval-valued intuitionistic fuzzy values by integrating the technique for order preference by similarity to an ideal solution and entropy weights to compare the effectiveness of different NM application patterns. These results offer practical insights for the application of NMs in similar multi-criteria decision-making scenarios, contributing to sustainable agriculture and global food safety. Nanomaterials positively impact staple food biomass production, reducing metal(loid) accumulation and mitigating oxidative damage in plants under stress conditions. This study provides practical insights into evaluating various nanomaterial application approaches, highlighting their potential for promoting sustainable agriculture and improving food safety.
