The future of ammonia use in 30 years: a deliberative experimental study envisioning the perspective of a future generation

Abstract Non-technical summary Humans are currently grappling with the challenge of nitrogen (N) management, which involves a multidimensional trade-off between the benefits of N use and the consequences of N pollution. For this study, a deliberative experiment was conducted in which five N scientists, divided into two groups, envisioned the future of NH 3 use in the 2050s, adopting the perspective of an imaginary future generation. Through this experience, the study encourages scientists to adopt the proposed framework and embrace freedom to explore desirable future visions, in addition to their usual task of empirically establishing universal disciplinary knowledge. Technical summary Humans are currently grappling with the challenge of nitrogen (N) management, which involves a multidimensional trade-off between the benefits of N use and the consequences of N pollution. The urgency to address this issue is already pronounced and may escalate further due to the emergence of ammonia (NH 3 ) as a carbon-free energy resource. For this study, a deliberative experiment was conducted in which five N scientists, divided into two groups, envisioned the future of NH 3 use in the 2050s, adopting the perspective of an imaginary future generation. The study revealed that some scientists encountered what is referred to in this study as the ‘positivist gap’, which involves difficulties forming narratives about unpredictable futures that rely on arbitrary assumptions. From this experience, this study develops and illustrates a framework that incorporates (i) Future Design workshops and (ii) abstracting operation for the workshop outputs. Although conducted in Japan, this study aims to inspire similar research in other countries. Social media summary A visioning experiment showed how scientists handle nitrogen trade-offs, imagining NH₃’s roles in a complex 2050 world.
