Healthier diets
Interest has grown in how to achieve healthy, sustainable, and affordable human diets. The potential income and employment effects of a transition towards healthier diets have received much less attention. We simulate aggregate and sectoral income and employment for business-as-usual and healthier diets for all geographic regions up to 2050 using scenario-based modelling. These healthier diets can increase food’s share of household expenditure in…
Bundling measures for food systems transformation
Affordability and nutritional challenges for the future of EAT diets
Income, consumer preferences, and the future of livestock-derived food demand
In recent decades there has been a sustained and substantial shift in human diets across the globe towards including more livestock-derived foods. Continuing debates scrutinize how these dietary shifts affect human health, the natural environment, and livelihoods. However, amidst these debates there remain unanswered questions about how demand for livestock-derived foods may evolve over the upcoming decades for a range of scenarios for key driver…

Are scenario projections overly optimistic about future yield progress
Key determinants of global land-use projections
Land use is at the core of various sustainable development goals. Long-term climate foresight studies have structured their recent analyses around five socio-economic pathways (SSPs), with consistent storylines of future macroeconomic and societal developments; however, model quantification of these scenarios shows substantial heterogeneity in land-use projections. Here we build on a recently developed sensitivity approach to identify how future …
Options for keeping the food system within environmental limits
Health and nutritional aspects of sustainable diet strategies and their association with environmental impacts
BACKGROUND: Sustainable diets are intended to address the increasing health and environmental concerns related to food production and consumption. Although many candidates for sustainable diets have emerged, a consistent and joint environmental and health analysis of these diets has not been done at a regional level. Using an integrated health and environmental modelling framework for more than 150 countries, we examined three different approache…
Income growth and climate change effects on global nutrition security to mid-century
Agricultural investments and hunger in Africa modeling potential contributions to SDG2 – Zero Hunger
We use IFPRI's IMPACT framework of linked biophysical and structural economic models to examine developments in global agricultural production systems, climate change, and food security. Building on related work on how increased investment in agricultural research, resource management, and infrastructure can address the challenges of meeting future food demand, we explore the costs and implications of these investments for reducing hunger in Afri…
Do markets and trade help or hurt the global food system adapt to climate change
Can sub-Saharan Africa feed itself?
Significance The question whether sub-Saharan Africa (SSA) can be self-sufficient in cereals by 2050 is of global relevance. Currently, SSA is amongst the (sub)continents with the largest gap between cereal consumption and production, whereas its projected tripling demand between 2010 and 2050 is much greater than in other continents. We show that nearly complete closure of the gap between current farm yields and yield potential is needed to main…
Climate change impacts on agriculture in 2050 under a range of plausible socioeconomic and emissions scenarios
Previous studies have combined climate, crop and economic models to examine the impact of climate change on agricultural production and food security, but results have varied widely due to differences in models, scenarios and input data. Recent work has examined (and narrowed) these differences through systematic model intercomparison using a high-emissions pathway to highlight the differences. This paper extends that analysis to explore a range …
A vision for attaining food security
Land Tenure and the Adoption of Conservation Practices
We use a logit adoption model with data on 941 U.S. corn producers from the 1996 Agricultural Resource Management Study to analyze the influence of land tenure on the adoption of conservation practices. We extend previous analyses by distinguishing renters according to lease type and by distinguishing practices according to the timing of costs and returns. We find that cash‐renters are less likely than owner‐operators to use conservation tillage,…
Land Tenure and Food Security
Land tenure and food security have each been the subject of extensive-but generally separate-research in the past. Links between the two issues are now receiving increased attention, yet critical links between them remain unexplored. After a brief review of the two concepts, this article combines both issues within a dynamic framework that recognizes not just the conventional link between access to land and access to food in the short run, but al…
