Bundling measures for food systems transformation
Integrated assessment model diagnostics
Integrated assessment models (IAMs) form a prime tool in informing about climate mitigation strategies. Diagnostic indicators that allow comparison across these models can help describe and explain differences in model projections. This increases transparency and comparability. Earlier, the IAM community has developed an approach to diagnose models (Kriegler (2015 Technol. Forecast. Soc. Change 90 45–61)). Here we build on this, by proposing a se…
The vulnerabilities of agricultural land and food production to future water scarcity
We examine risks to current agricultural land to future changes in water availability. • We present a multiple model inter-comparison of future land demand and water availability. • Eleven percent of croplands and ten percent of grasslands are at risk from declining water availability. • Changes in diet and waste reduction offer a buffer against land loss and food insecurity. Rapidly increasing populations coupled with increased food demand requi…
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 …
Land-use change trajectories up to 2050
Changes in agricultural land use have important implications for environmental services. Previous studies of agricultural land-use futures have been published indicating large uncertainty due to different model assumptions and methodologies. In this article we present a first comprehensive comparison of global agro-economic models that have harmonized drivers of population, GDP, and biophysical yields. The comparison allows us to ask two research…
Climate change effects on agriculture
Significance Plausible estimates of climate change impacts on agriculture require integrated use of climate, crop, and economic models. We investigate the contribution of economic models to uncertainty in this impact chain. In the nine economic models included, the direction of management intensity, area, consumption, and international trade responses to harmonized crop yield shocks from climate change are similar. However, the magnitudes differ …
The future of food demand
Understanding the capacity of agricultural systems to feed the world population under climate change requires projecting future food demand. This article reviews demand modeling approaches from 10 global economic models participating in the Agricultural Model Intercomparison and Improvement Project (AgMIP). We compare food demand projections in 2050 for various regions and agricultural products under harmonized scenarios of socioeconomic developm…
Implications of Limiting CO 2 Concentrations for Land Use and Energy
The Power of Green Carbon dioxide is produced both by fossil fuel burning and by deforestation and other land-use changes. Limiting both sources of CO 2 is necessary if we are to curb global warming. Wise et al. (p. 1183 ) use an integrated assessment model to explore the consequences of limiting atmospheric CO 2 concentrations at levels between 450 and 550 parts per million through a combination of fossil-fuel emissions reductions and land-use m…
