Climate change research is at an impasse. The transformation of economies and everyday practices is more urgent, and yet appears ever more daunting as attempts at behaviour change, regulations, and global agreements confront material and social-political infrastructures that support the status quo. Effective action requires new ways of conceptualizing society, climate and environment and yet current research struggles to break free of established categories. In response, this contribution revisits important insights from the social sciences and humanities on the co-production of political economies, cultures, societies and biophysical relations and shows the possibilities for ontological pluralism to open up for new imaginations. Its intention is to help generate a different framing of socionatural change that goes beyond the current science-policy-behavioural change pathway. It puts forward several moments of inadvertent concealment in contemporary debates that stem directly from the way issues are framed and imagined in contemporary discourses. By placing values, normative commitments, and experiential and plural ways of knowing from around the world at the centre of climate knowledge, we confront climate change with contested politics and the everyday foundations of action rather than just data.

Climate change is a severe global threat. Research on climate change and vulnerability to natural hazards has made significant progress over the last decades. Most of the research has been devoted to improving the quality of climate information and hazard data, including exposure to specific phenomena, such as flooding or sea-level rise. Less attention has been given to the assessment of vulnerability and embedded social, economic and historical conditions that foster vulnerability of societies. A number of global vulnerability assessments based on indicators have been developed over the past years. Yet an essential question remains how to validate those assessments at the global scale. This paper examines different options to validate global vulnerability assessments in terms of their internal and external validity, focusing on two global vulnerability indicator systems used in the WorldRiskIndex and the INFORM index. The paper reviews these global index systems as best practices and at the same time presents new analysis and global results that show linkages between the level of vulnerability and disaster outcomes. Both the review and new analysis support each other and help to communicate the validity and the uncertainty of vulnerability assessments. Next to statistical validation methods, we discuss the importance of the appropriate link between indicators, data and the indicandum. We found that mortality per hazard event from floods, drought and storms is 15 times higher for countries ranked as highly vulnerable compared to those classified as low vulnerable. These findings highlight the different starting points of countries in their move towards climate resilient development. Priority should be given not just to those regions that are likely to face more severe climate hazards in the future but also to those confronted with high vulnerability already.

Women's empowerment has gained attention as critical for child nutrition during the first 1000 days of life. However, the ways in which various women's empowerment measures are applied and the evidence for how they are differentially related to child nutrition is unclear. In this systematic review, therefore, we 1) systematically parse the many ways in which women's empowerment has been quantitatively measured in the context of child nutrition through the use of a theoretically driven application of dimensions and domains of empowerment; 2) summarize evidence for each of the various pathways between women's empowerment and child nutrition, based on dimensions and domains of empowerment; and 3) offer suggestions for future research to better articulate the relationship between women's empowerment and child nutrition. A search of evidence yielded 62 quantitative studies that used 200 unique indicators of women's empowerment, tested in 1316 associations with various child nutrition outcomes. Despite the large number of unique indicators, indicators for time resource allocation and reproductive decisions and indicators for men's engagement in child care and nutrition, all pertinent to child nutrition, were missing. Overall, the findings indicated an inconclusive relationship between women's empowerment and child nutrition: 379 out of 461 (82% weighted) and 217 out of 258 (84% weighted) associations found with stunting and wasting outcomes, respectively, were not significant. The current lack of evidence is likely not due to the absence of an underlying relationship between women's empowerment and child nutrition, but rather limitations in study design. Future research should carefully select women's empowerment indicators in context-specific ways, aggregate them meaningfully, and use a longitudinal study design to conduct pathway and lifecycle analysis in appropriate populations to clarify the relationship between women's empowerment and child nutrition.

Agricultural simplification continues to expand at the expense of more diverse forms of agriculture. This simplification, for example, in the form of intensively managed monocultures, poses a risk to keeping the world within safe and just Earth system boundaries. Here, we estimated how agricultural diversification simultaneously affects social and environmental outcomes. Drawing from 24 studies in 11 countries across 2655 farms, we show how five diversification strategies focusing on livestock, crops, soils, noncrop plantings, and water conservation benefit social (e.g., human well-being, yields, and food security) and environmental (e.g., biodiversity, ecosystem services, and reduced environmental externalities) outcomes. We found that applying multiple diversification strategies creates more positive outcomes than individual management strategies alone. To realize these benefits, well-designed policies are needed to incentivize the adoption of multiple diversification strategies in unison.
