The first instrument is an information campaign on tree planting in oil palm. The second instrument combines the information campaign with a structural intervention that provides native tree seedlings for free. We implemented a randomized controlled trial in oil palm growing villages in Jambi, Indonesia. Our study addresses the underlying mechanisms of behavioral change, by investigating how the policy instruments shape farmers’ perceptions, intentions and actual adoption decisions. The results show that information campaigns and structural interventions can motivate tree planting among smallholder oil palm farmers in Indonesia. While both treatments have a positive and significant effect, the intervention combining information with seedling provision leads to significantly higher adoption rates, indicating that overcoming structural barriers is critical. While changes in perceptions and intentions fully mediate the effect of the information campaign on adoption, they can only partially explain the effect of the combined intervention. Thus, to promote a transition towards more sustainable development pathways, facilitating easy access to critical inputs may be key to motivate adoption among large numbers of potential users."],["dc.format.extent","28"],["dc.identifier.ppn","106777694X"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/108106"],["dc.language.iso","en"],["dc.publisher","SFB 990, University of Göttingen; GOEDOC, Dokumenten- und Publikationsserver der Georg-August-Universität Göttingen"],["dc.publisher.place","Göttingen"],["dc.relation","SFB 990: Ökologische und sozioökonomische Funktionen tropischer Tieflandregenwald-Transformationssysteme (Sumatra, Indonesien)"],["dc.relation","SFB 990 | C | C08: Design effektiver Politikinstrumente zur Förderung nachhaltiger Landnutzung"],["dc.relation.crisseries","EFForTS Discussion Paper Series"],["dc.relation.orgunit","Johann-Friedrich-Blumenbach-Institut für Zoologie und Anthropologie"],["dc.rights","CC BY-NC-ND 4.0"],["dc.subject.gro","tree-planting; oil palm; intentions; mediation; Asia"],["dc.subject.gro","sfb990_discussionpaperseries"],["dc.title","Promoting sustainable land use choices in Indonesia"],["dc.title.subtitle","experimental evidence on the role of changing mindsets and structural barriers"],["dc.type","working_paper"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

While this dichotomy highlights the importance of sustainable management options, empirical evidence on which policies are effective in stimulating biodiversity-friendly plantation management is relatively scarce. This paper addresses this gap by presenting results from a randomized controlled trial implemented in Jambi province, Sumatra, in 2016. We focus on native tree planting in oil palm plantations as one sustainable management option. To test whether information and input provision affect the number of trees planted by smallholders two treatments were designed: the first provided information about tree planting in oil palm, while the second combined information and seedling delivery. We model adoption in a double-hurdle framework where farmers first decide whether to adopt or not and then how many trees they plant per hectare. Our results suggest that both interventions are effective in stimulating tree planting in oil palm. Seedling provision in combination with information leads to a higher probability of adoption, but farmers plant on average relatively few trees per hectare. In contrast, in the informational treatment, few farmers adopt, but they plant more trees per hectare than farmers who received seedlings. Furthermore, we observe that the survival rate of trees planted is lower for farmers who received seedlings in comparison to farmers who only received information. Since we cannot find evidence for farmer and plot selection effects, it is likely that species choice and seedling quality are the underlying drivers of this difference.
