This volume of International Development Policy brings together post-extractivist imaginaries, diverse and ever-evolving forms of resistance and contestation, and a growing recognition of the paradox of ‘green’ extractivism. Despite the pervasive narrative that more rather than less mining is necessary to achieve decarbonisation, there is now growing recognition that the current model of economic development based on fossil fuels and resource extraction is not sustainable in the long term. The introduction to this volume acknowledges the complex and ongoing legacies of extraction and the urgent need to move beyond extractive models of development and towards alternative pathways that prioritise social justice, environmental sustainability, democratic governance, and the well-being of both human and non-human beings. Ce volume rassemble des imaginaires post-extractivistes, des formes de résistance et de contestation diverses et en constante évolution, ainsi qu'une reconnaissance croissante du paradoxe de l'extractivisme ‘vert’. Malgré le discours omniprésent selon lequel il faut plus et non moins d'exploitation minière pour parvenir à la décarbonisation, il est de plus en plus admis que le modèle actuel de développement économique basé sur les combustibles fossiles et l'extraction des ressources n'est pas viable à long terme. L'introduction de ce volume reconnaît les héritages complexes et continus de l'extraction et le besoin urgent de dépasser les modèles extractifs de développement et d'emprunter des voies alternatives qui donnent la priorité à la justice sociale, à la durabilité environnementale, à la gouvernance démocratique et au bien-être des êtres humains et non-humains. Este volumen reúne imaginarios postextractivistas, formas de resistencia y contestación diversas y en constante evolución, y un creciente reconocimiento de la paradoja del extractivismo "verde". A pesar de la omnipresente narrativa de que para lograr la descarbonización se necesita más y no menos minería, cada vez se reconoce más que el actual modelo de desarrollo económico basado en los combustibles fósiles y la extracción de recursos no es sostenible a largo plazo. En la introducción de este volumen se reconocen los complejos legados de la extracción y la urgente necesidad de ir más allá de los modelos extractivos de desarrollo y avanzar hacia vías alternativas que den prioridad a la justicia social, la sostenibilidad medioambiental, la gobernanza democrática y el bienestar de los seres humanos y no humanos.

Traceability is an increasingly prominent research topic in decentralised technosocial systems in fields as diverse as health, sustainability, finance, and supply chain management. At the same time, traceability connotes different meanings and potentialities within each of these fields. This Glossary article homes in on “traceability” as a concept that is deceptively simple but fundamentally crucial in blockchain technologies. First, the entry provides an overview of the historical background of traceability within digital technologies. The entry then outlines the most critical dimensions of the concept by relating the term to questions about accountability, explainability, and speculation. Finally, emergent methodological and theoretical insights concerning traceability as a paradoxical concept in distributed technologies are highlighted.

Two investigations are described in this thesis on the common theme of applying finite volume methods to simulate structural impact problems. The first investigation is the application of the Eulerian Finite Volume Method (EFVM) to simulate the low-speed impact of ductile materials. Simulation results are validated against experiment showing that it is possible to accurately predict crater deformation profiles over the low speed speed impact regime for different projectile and substrate materials. We demonstrate how the rate dependent Johnson-Cook plasticity model is crucial to ensure correspondence to experiment. The second investigation is concerned with the application of EFVM to simulate impact damage to thin polymeric coatings applied to the surface of metals. The aim of this work is to demonstrate how new simulation methods can help understand coating damage due stone impact. We simulate the debonding phenomenon of single layer coatings under impact by setting boundary conditions at the plate and paint interface. We show how EFVM can capture two limits of interface behaviour, sliding and separation 'slip' at one extreme and zero sliding 'welded' at the other. Results compare well to previously published experimental and simulation work, and our own finite element simulations in Abaqus. We also demonstrate how EFVM brings greater robustness and stability compared to FEM when modelling adhesive failure and higher energy impact penetration.
