Bundling measures for food systems transformation: A global, multimodel assessment

Background Current food systems leave one in ten individuals at risk of hunger while driving unsustainable environmental impacts. Inaction risks further exacerbating negative impacts on both human and planetary health. These challenges emerge from complex system interactions, requiring approaches that engage with this complexity and consider how transformation measures interact across food systems. We aimed to quantify the magnitude and uncertainty of the impacts of key food systems transformation measures both individually and in a bundle using an ensemble of global economic models. Methods In this global multimodel assessment, we applied an ensemble of ten state-of-the-art global economic models to evaluate the potential of four key measures in transforming food systems: increasing agricultural productivity, halving food loss and waste, shifting towards healthier diets, and economy-wide climate mitigation policies aligned with limiting warming to 1·5°C. The scenarios used a middle-of-the-road shared socioeconomic pathway for population and gross domestic product growth, climate impact data from Jägermeyr and colleagues, Thornton and colleagues, and Nelson and colleagues, and dietary targets based on the EAT–Lancet healthy reference diet, with model simulations conducted from 2020 to 2050. We then assessed the effect of these measures in isolation and in combination in a bundled scenario. To further understand the interactions between these measures, we conducted a decomposition analysis that distinguishes between the individual effects of a measure (effect when implemented alone), total effects (its contribution within the bundle), and interaction effects (the difference between total and individual effects). This approach aimed to show complementarities and trade-offs that emerge when multiple measures are implemented simultaneously. Findings Our analysis showed that individual measures in isolation are insufficient to achieve high-level environmental objectives and might generate unintended consequences. In contrast, bundling measures produces co-benefits: avoiding 50% of projected agricultural greenhouse gas emissions by 2050 and almost 20% of anticipated land conversion, while moderating food price increases associated with ambitious climate change mitigation policies. Our decomposition analysis further shows that measures can have varying effects across different dimensions. Although dietary shifts and climate mitigation policies are the largest drivers of environmental benefits (each contributing to a median decline of >10 percentage points in non-CO2 emissions and 5 percentage points in agricultural land use globally), productivity improvements and reducing food loss and waste play essential roles in moderating price increases (each contributing to a median decline of >5 percentage points in average prices). Interpretation This study highlights the importance of implementing coordinated approaches to food system transformation and climate change mitigation rather than relying on isolated interventions. Comprehensive transformation requires understanding how supply-side and demand-side changes can interact with climate mitigation policies, enabling policy makers to design intervention packages that maximise benefits while minimising trade-offs across environmental, economic, and social dimensions.

Women’s leadership in agrifood governance: Unpacking gender attitudes and framing effects among policymakers with evidence from India and Nigeria

Women’s leadership in policy processes and formal institutions is a powerful pathway to gender equality and women’s empowerment at scale, yet relatively little is known about how key decision-makers who influence access to these positions perceive women’s leadership and how those perceptions can shift. This paper draws on original survey data from 407 elites from 274 agrifood organizations in India and Nigeria to examine elite gender attitudes, their responsiveness to framing interventions, and how these attitudes relate to support for policies promoting gender equality. Specifically, we ask: how do elites in agrifood governance perceive women’s leadership, and how responsive are these perceptions to a targeted framing intervention? We find that elites are substantially more supportive of women’s leadership than the general public in the same countries, yet male elites in particular still express strong endorsement of the idea that men make better leaders. Over half of male elites in our sample in both countries agree that men make better political leaders. A randomized framing experiment embedded in the survey shows that men’s attitudes toward women’s leadership are significantly influenced by how women’s capabilities are framed. Messages emphasizing women’s equal rights and capabilities reduce male elites’ support for gender-unequal statements compared to frames that ask individuals to reject the idea of male superiority. Female elites’ attitudes are more supportive overall and unaffected by framing. These findings suggest that gender messaging strategies should center on positive, equality-based frames, and that elite attitudes are critical to scaling women’s leadership in agrifood governance.
