https://www.eco-monist.com/ I am an interdisciplinary sustainability science researcher interested in social and conceptual dimensions of biodiversity, ecosystem services, and human-nature connections. A key tension explored in my work is that between abstract systems of categorization, such as those central to ecosystem services, and people's varied perceptions of nature and embodied experiences in natural environments.Current projects: "The role of local knowledge in assessments of biodiversity loss and climate change impacts" (Formas The Swedish Research Council for Environment 2023-2027)The aim of this project is to develop the methodology for the integration of scientific and local knowledge in assessments of biodiversity loss and climate change impacts, in order to provide for more comprehensive and just assessments. The project combines conceptual analysis and literature reviews with empirical case studies focusing on regulated rivers in Sweden, which provides a critical case for complex trade-offs between local biodiversity freshwater degradation and fossil free hydroelectric power benefits."Numeric trees and measurable ecosystem services: threats and opportunities for sustainable urban planning" (Formas The Swedish Research Council for Environment 2023-2026)This project responds to concerns of risks of the effect of technologies that translate nature into monetary measures, and challenges in applying generic metrics for place-specific governance. The aim is to scrutinise if valuation of urban trees result in more sustainable planning and decision-making. By following an STS approach, we analyse how the I-Tree software tool quantifies and monetises trees, and outline the network of interactions between scientists, consultancies, planners and developers, as well as analyse the interpretations and outcomes of tree valuation.https://www.slu.se/cv/sanna-stalhammar/https://www.researchgate.net/profile/Sanna-Stalhammar
