As a result, the contribution of farmers to domestic food production is a poor proxy for their role in national food security. This study offers the first global assessment of how small-, medium-, and large-scale farmers contribute to global food security. We find that the role of small-scale farmers in national and global food security has been significantly underestimated due to the localised focus of previous studies, particularly in high-income nations. Future research must account for the differentiated roles, impacts, and vulnerabilities of farmers within a global context. Show less

Show moreThis report aims to provide a primer for CGE practitioners to understand the potential to link micro (i.e., Life Cycle Assessment (LCA) and Dynamic Material Flow Analysis (DMFA)) and CGE models to model circular economy strategies. The report offers an overview of the state-of-the-art of LCA/DMFA and CGE model linkages (including 8 archetypes), key lessons from LCA/DMFA studies to macro-modelling approaches, and an example of substituting internal combustion engine vehicles with electric vehicles, considering the circularity potential of Li-ion batteries to illustrate the application of micro- and macro-modelling linkages towards circular economy scenarios.
