Yet, it remainsunclear what strategies are most effective to inform andactivate support for climate action. This paper presentsthe results of a randomized controlled trial in Indonesiathat evaluated how local climate information and differentfacilitation strategies for group decision-making on localdevelopment spending impacted preferences for climateadaptation and mitigation. In the first treatment, partici-pants watched an educational video on climate change anda presentation on local climate vulnerabilities; in the second,they discussed and voted on spending priorities for local development funds after receiving the same educationalmaterials; and in the third, they deliberated over groupspending priorities after receiving the educational materials,discussing, and voting. The findings show that participantswho engaged in deliberation about the allocation of localfunding demonstrated significantly greater support for cli-mate adaptation and mitigation actions as compared to allother groups. Further, they showed a statistically significantincrease in their preferences for climate action after theintervention. The findings demonstrate the importanceof sharing accessible information and using deliberativeapproaches to foster local support for climate action. The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about developmentissues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry thenames of the authors and should be cited accordingly.

Nature-based solutions refer to the suite of actions that rely on the protection,management, or restoration of natural systems to address societal challenges while enhancing human well-being and protecting biodiversity (Ellis 2024, Seddon 2022, Cook et al. 2021, Chausson 2020). Over 80%of all revised Nationally Determined Commitments (NDCs) to the Paris Climate Agreement include nature-based solutions (Seddon 2022). If selected and implemented by indigenous people and local communities(IPLCs), nature-based solutions can also empower local governance (Erbaugh et al. 2020). There is a long history of communities selecting and implementing conservation actions includingnature-based solutions. Research on community-based forest, fisheries, and rangeland management hashighlighted local actions that promote the sustainable use of natural resources (Agarwal et al. 2023). Suchactions demonstrate benefits for biodiversity and provide numerous environmental and human well-beingbenefits, such as sustained improvements in economic benefits and health (Jones et al. 2020, Miller andHajjar 2019). Observational studies, laboratory experiments, and games in the field support the finding thatcommunication among individuals is critical for coordinating preferences to deliver prosocial outcomes forconservation and sustainable resource use (Andersson et al. 2018, Moreno-Sanchez and Maldonado 2010,Villamor and Badmos 2016, Cardenas et al. 2011). Despite conclusive evidence on the importance ofcommunication for sustainable resource governance, these studies rarely focus on how to facilitate effectivecommunication or the relationship between communication and citizen deliberation as a means to addresslocal interest in climate action. Research on climate change communication and deliberative democracy, however, highlights thepromise of well-designed communication interventions. Climate communication research finds thatproviding general information on climate change along w
