Intensifying, interdependent Anthropocene crises reveal disruptions that can be understood as the failure of human semiotic systems to comprehend nonhuman entities within enmeshed symbolic and environmental ecologies. Employing a semi-anthropological lens that bridges nature-culture divides, this semiotic analysis views ecophenomena (e.g., biodiversity collapse and human-induced climate change) as signs of upheaval resulting from inadequate frameworks for rendering nonhuman Umwelten (lifeworlds) intelligible to human systems. Economic models, in particular, have historically failed to account for human-nonhuman interdependencies by centering capital expansion that inherently encodes extractive paradigms that harm ecological systems.My analysis applies a biosemiotics lens to The Economics of Biodiversity: The Dasgupta Review, as an artifact attempting to integrate nature’s value into economic decision-making. I examine whether and how Dasgupta’s framework allows market signs to register semiotic subjects and their Umwelten as legible/illegible. By analyzing this attempt to integrate nonhuman semiotics into economics, I reconsider whether such economic semiotic regimes can or do recognize nonhuman agencies as semiotic agents intertwined with human meaning-making to material effect, as well as what such recognition might look like.Examining Dasgupta’s work potentiates possible frameworks for biosemiotic attunement and multispecies semiotics as vital for redesigning symbolic and material ecosystems’ limiting anthropocentric frameworks through new sign recognition. Such work enables more holistic economic models valuing nonhuman lifeworlds and their intra-active relationships with human societies as oft-ignored signs within shared semiotic ecologies.
