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"]]

Data from a structured village survey are used to analyze the role of soci- oeconomic and policy factors. Oil palm is partly grown on large plantations, but smallholders are also involved significantly. We find that, in spite of significant oil palm expansion, rubber remains the dominant crop. Most of the oil palm growth takes place on previous fallow and rubber land. Oil palm has not been a major driver of deforestation. Much of the forest in Ja m- bi was cleared more than 20 years ago, and rubber was an established cash crop long before the oil palm boom started. However, oil palm growth occurs in locations with ongoing log- ging activities, so indirect effects on deforestation are likely. The government’s transmigra- tion program of the 1980s and 1990s was instrumental for the start and spread of oil palm in Jambi. Some autochthonous villages have adopted oil palm, but adoption started later com- pared to migrants from Java, and it happens at a slower pace. While the transmigration pro- gram benefited many of the participating families, it has contributed to the risk of unequal so- cioeconomic developments in Jambi."],["dc.format.extent","III, 20"],["dc.identifier.ppn","789836130"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/108089"],["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 | C07: Einflussfaktoren von Landnutzungswandel und sozioökonomische Auswirkungen für ländliche Haushalte"],["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-ND 4.0"],["dc.subject.gro","Oil palm, land-use change, deforestation, socioeconomic factors, Indonesia, gov- ernment policy"],["dc.subject.gro","sfb990_discussionpaperseries"],["dc.title","Oil palm boom and land-use dynamics in Indonesia"],["dc.title.subtitle","The role of policies and socioeconomic factors"],["dc.type","working_paper"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

In this paper, we investigate the effects of contract farming on economic development at the village level. At the same time, little is understood regarding the fac- tors that determine that cohorts of farmers sign a contract. Analyzing data from a structured village survey, we find a positive effect of contract farming schemes on economic development, in particular on village wealth. The share of farmers under contract and contract length play a significant role in this. Regarding contract adoption, we observe that contract participation is conditional on the visit of a private investor. Controlling for this conditionality, we find that villages that have no access to elec- tricity are more likely to participate in community-company partnerships. Finally, considering the gov- ernment\\’s intention to spur rural economic development through contract farming and the positive wealth effects associated with it, we find that contract farming has not been entirely equally accessible; however, we do not find evidence that the rural poor were excluded."],["dc.format.extent","IV, 27"],["dc.identifier.ppn","82392873X"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/108094"],["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 | C07: Einflussfaktoren von Landnutzungswandel und sozioökonomische Auswirkungen für ländliche Haushalte"],["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-ND 4.0"],["dc.subject.gro","Oil palm; contract farming; rural development; Indonesia"],["dc.subject.gro","sfb990_discussionpaperseries"],["dc.title","Oil Palm Boom, Contract Farming, and Village Development"],["dc.title.subtitle","Evidence from Indonesia"],["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.
