  • Assessing the performance of an economy in times of crisis is a difficult task. This study presents an agent-based model capturing the behaviour of firms facing transport and supply disruptions due to natural disasters, and shows possible paths to reinforce infrastructure and supply chain resilience.

  • Banning the sale of rinse-off cosmetics containing plastic microbeads to protect the environment requires understanding the lifetime environmental impacts of potential substitutes. By comparing the environmental performance of alternatives, this study finds viable substitutes and those with adverse effects.

    Article
  • The Indus river basin in South Asia is water stressed, energy insecure and intensively farmed, and research on this region often lacks a systemic approach to the issues. This study shows how the path to development in the region could be made less costly and more environmentally friendly by fostering transboundary cooperation.

  • Our expert panel on food value chains now shares recommendations on how to transform agri-food systems.

    Editorial
  • Coupling technological advances with sociocultural and policy changes can transform agri-food systems to address pressing climate, economic, environmental, health and social challenges. An international expert panel reports on options to induce contextualized combinations of innovations that can balance multiple goals.

    Comment
  • Perovskite solar cell (PSC) technology is moving closer to commercialization but the ecotoxicity of the solvents involved in perovskite processing remains a barrier. A study now identifies a green solvent that can help PSC sustainability and scalability.

    Analysis
  • Perovskite solar cells could be a game-changing energy technology. However, the solvents involved during fabrication pose sustainability concerns. Here, the authors provide an analysis of human health toxicity and environmental implications of handling solvents, recommending dimethyl sulfoxide (DMSO) as the green choice for large-scale production.
