Abstract Greenhouse gas removal technologies and practices are essential to bring emissions to net zero and limit global warming to 1.5 °C. To achieve this, the majority of integrated assessment models (IAMs), that generate future emissions scenarios and inform the international policy process, use large-scale afforestation and biomass energy with carbon capture and storage (BECCS). The feasibility of these technologies and practices has only so far been considered from a relatively narrow techn...

Abstract Global greenhouse gas (GHG) emissions models generally project a downward trend in CO2 emissions from land use change, assuming significant crop yield improvements. For some crops, however, significant yield gaps persist whilst demand continues to rise. Here we examine the land use change and GHG implications of meeting growing demand for maize. Integrating economic and biophysical models at an unprecedented spatial resolution, we show that CO2 emissions from land conversion may rise sh...

Abstract Achieving food and nutrition security for all in a changing and globalized world remains a critical challenge of utmost importance. The development of solutions benefits from insights derived from modelling and simulating the complex interactions of the agri-food system, which range from global to household scales and transcend disciplinary boundaries. A wide range of models based on various methodologies (from food trade equilibrium to agent-based) seek to integrate direct and indirect...

Abstract Interactions between researchers and practitioners can lead to the increased use of climate science in decision-making. Past studies on these interactions have focused on the information needs of decision-makers, but less is known about why and how climate researchers choose to engage with decision-makers. Understanding the experiences, beliefs and constraints on both sides of the ‘knowledge-action gap’ is critical for implementing robust climate adaptation strategies. This study thus e...

Abstract Millions of humans across the globe depend on lakes for numerous ecosystem services. Furthermore, humans use lakes as a food source and for a multitude of economic activities. Lakes are also essential to a plethora of taxa that rely on them for survival. Yet, despite the importance of lakes, we still lack an assessment of the extent lakes worldwide are being influenced by anthropogenic activities. In this study, I use the global database of lakes, the human footprint index from 1993 and...

Abstract The continued rise of global disaster losses pushes our attention yet further to the causal factors that drive risks, beyond the frame of standardised risk assessment models. A key gap in our understanding of the causality of disasters remains establishing how spatially and temporally distant factors – ‘root causes’ – drive local risk conditions. This is particularly the case for small-scale but high-impact disasters. It includes understanding the role that institutions play in influenc...

Abstract Copper is widely used in modern technology, but declining ore grades and depletion of natural deposits have raised concerns regarding sustainable demand-supply balance in the long term. The vulnerability to primary copper supply restrictions amplifies for countries dependant on imports, notably many EU Member States. Recycling of post-consumer scrap can provide a valuable source of essential material to the European industry. However, a considerable fraction of collected and processed c...

Abstract There is increasing interest in protecting, restoring and creating ‘blue carbon’ ecosystems (BCE; mangroves, tidal marshes and seagrasses) to sequester atmospheric CO2-C and thereby contribute to climate change mitigation. While a growing number of countries aspire to report greenhouse gas emission and carbon sequestration changes from these ecosystems under voluntary international reporting requirements, few countries have domestic policy frameworks that specifically support the quanti...

Abstract We assess economic costs of heat-induced reductions in worker productivity at global scale under RCP2.6 and RCP8.5. Losses in worker productivity are calculated by using an empirically estimated epidemiological exposure-response function, and the associated economic costs are assessed by using a dynamic multi-region, multi-sector computable general equilibrium model. Autonomous mechanisation of outdoor work in agriculture and construction is implemented in the model. We find that under ...
