Different places, different challenges: Mapping global variations in agrifood-system burdens
The global agrifood system is central to many challenges humanity faces today. Despite significant growth in total production, it fails to ensure food security for all, drives biodiversity decline, and majorly contributes to climate change. Research on agrifood-system burdens often focusses on the national level and isolated burdens, ignoring their systemic complexity. We address this knowledge gap by combining global subnational datasets proxyin…
Exposure of global agricultural lands to extreme weather using CMIP6 projections of future climate
As climate change intensifies, extreme weather is becoming a major threat to global food security. Yet we still lack a good understanding of how these extremes will be distributed across the world’s agricultural lands—particularly across small versus large croplands and pasturelands. In this study, we assess their exposure to extreme weather in a warming world. In a world that is 2 °C warmer than today, 25% (11 million km 2 ) of present-day agric…
Nutrition-sensitive climate risk across food production systems
Global nutrition targets remain unmet, as over half of preschool-aged children and two-thirds of non-pregnant women of reproductive age worldwide suffer from micronutrient deficiencies. Climate change poses a growing threat to global food and nutrition security, but existing climate risk assessments often overlook the critical roles of both terrestrial and aquatic nutrient-rich foods that are vital for dietary diversity and micronutrient supply. …

Against the odds: Network and institutional pathways enabling agricultural diversification
How can machine learning help in understanding the impact of climate change on crop yields
Ordinary least squares linear regression (LR) has long been a popular choice among researchers interested in using historical data for estimating crop yield response to climate change. Today, the rapidly growing field of machine learning (ML) offers a wide range of advanced statistical tools that are increasingly being used for more accurate estimates of this relationship. This study compares LR to a popular ML technique called boosted regression…
Likely decline in the number of farms globally by the middle of the century
Research priorities for global food security under extreme events
Extreme events, such as those caused by climate change, economic or geopolitical shocks, and pest or disease epidemics, threaten global food security. The complexity of causation, as well as the myriad ways that an event, or a sequence of events, creates cascading and systemic impacts, poses significant challenges to food systems research and policy alike. To identify priority food security risks and research opportunities, we asked experts from …
Digital technology helps remove gender bias in academia
More farms, less specialized landscapes, and higher crop diversity stabilize food supplies
Theoretical and empirical studies show increased diversity in crops, supply chains, and markets helps stabilize food systems. At the same time global commodity markets and industrial agriculture have driven homogenization of local and regional production systems, and consolidated power in fewer larger specialized farms and distributers. This is a global challenge, with no obvious global solutions. An important question therefore, is how individua…
Higher yields and more biodiversity on smaller farms
The global divide in data-driven farming
Incomplete transitions to clean household energy reinforce gender inequality by lowering women’s respiratory health and household labour productivity
The structures underpinning vulnerability: Examining landscape-society interactions in a smallholder coffee agroforestry system
Smallholder farmers dependent on rain-fed agriculture are particularly vulnerable to extreme climate events and, therefore, it is necessary to identify adaptive measures that would increase farmer resilience to these shocks. The management options in a low-input system, like forest coffee ( Coffea arabica ), are limited and there are several factors out of farmers’ control driving their vulnerability to changing climatic conditions. These can rel…

Half Earth: Promises, pitfalls, and prospects of dedicating Half of Earth’s land to conservation
Trends in Global Agricultural Land Use: Implications for Environmental Health and Food Security
The eighteenth-century Malthusian prediction of population growth outstripping food production has not yet come to bear. Unprecedented agricultural land expansions since 1700, and technological innovations that began in the 1930s, have enabled more calorie production per capita than was ever available before in history. This remarkable success, however, has come at a great cost. Agriculture is a major cause of global environmental degradation. Ma…
How much of the world's food do smallholders produce?
The widely reported claim that smallholders produce 70–80% of the world’s food has been a linchpin of agricultural development policy despite limited empirical evidence. Recent empirical attempts to reinvestigate this number have lacked raw data on how much food smallholders produce, and have relied on model assumptions with unknown biases and with limited spatial and commodity coverage. We examine variations in crop production by farm size using…
