GLASSNET’s impact on key stakeholders will make a difference in achieving the SDGs. Our network has the potential to provide decision makers from a wide-array of areas with the data needed to properly assess actions that will affect the environment, the economy and local communities.

Benjamin is a Senior Scientist at the Potsdam Institute for Climate Impact Research (PIK). He recently presented at the GLASSNET SDG Workshop: Quantitative Modelling of Sustainable Development Pathways where he discusses his research. He is curious about the global land system and food system. What are the large-scale and long-term transitions of these systems? What are the drivers and dynamics behind these changes? What are the spatial patterns? What are the consequences for the environment, dietary health and inequality? And, most of all, how could we create the political conditions for a sustainable food system? Listen to Benjamin Bodirsky discuss "A vision for a desirable food system" and the role of mathematical models here.

The current global food system has detrimental outcomes for global health, environmental conditions and social inclusion. A coherent vision of a desirable food system can guide a sustainable food system transformation and help to structure political processes and private decisions by quantifying potential benefits, facilitating debates about co-benefits and trade-offs, and identifying key measures for desirable change. Such a transformation requires integrating measures targeting human diets, livelihoods, biosphere integrity, and agricultural management.
Here, we apply a global food and land system modeling framework to quantify the impacts of 23 food system measures by 2050. Our multi-criteria assessment shows that a food system transformation can improve outcomes for health, the environment, social inclusion, and the economy. All individual measures come with trade-offs, particularly those targeting agricultural management, while few trade-offs and multiple co-benefits are linked to dietary change measures. By combining measures in packages, trade-offs can be reduced and co-benefits enhanced. We show that a sustainable food system also requires a transformation of the overall economy to stop global warming, reduce absolute poverty, and create alternative employment options. Within the context of a cross-sectoral sustainable development pathway, the food system transformation improves 14 of our 15 outcome indicators.
Understanding Climate Impacts on 21st Century Crop Yield from the GGCMI Network
June 18, 2024
Recently the Global Gridded Crop Model Intercomparison (GGCMI – a GLASSNET network member) has published a paper documenting their latest findings about crop yield impacts of climate changes over the 21st century: Nature.com. Through the updated ‘AgMIP tool’ on the GeoHub, GLASSNET has made these results, along with a convenient aggregation tool, available to the community. The new results are quite different from earlier crop impacts and this workshop will assemble lead authors of the paper, the AgMIP tool, and users of these results to discuss the implications for integrated assessments of climate change. The three discussants will bring diverse perspectives on these new findings, as well as discussing their implications for GLASSNET related research.
