Authors: Brenneis, Karina; Irawan, Bambang; Wollni, Meike
Abstract: Agricultural technologies frequently have been introduced via subsidies to accelerate diffusion and spur adoption in the presence of market inefficiencies or missing information. Yet, for agricultural technologies that mainly generate positive environmental effects, it is not clear how to encourage adoption, maintenance, and additional investments most effectively. This study addresses this gap by introducing two policy interventions to foster tree planting in an oil palm hotspot in Indonesia. In the first treatment, oil palm farmers receive information about native tree planting and three different native tree seedlings for free (subsidy treatment). In the second treatment, oil palm farmers receive the same information and the opportunity to buy three different native tree seedlings through an auction (price treatment). Results from negative binomial regressions reveal that a full subsidy leads to higher tree planting at first, but the results from a double hurdle model show that conditional on being planted there is no significant difference in survival rates between the two treatments. Our results further show that conditional on tree planting farmers in the price treatment apply a higher number of maintenance practices than farmers in the subsidy treatment. Finally, the subsidy treatment has a significantly negative effect on additional planting efforts.</summary>

Authors: Brenneis, Karina; Edison, Edi; Asnawi, Rosyani; Wollni, Meike
Abstract: Oil palm is the most significant boom crop in Southeast Asia and associated with tremendous negative environmental effects. These environmental effects can influence the environmental concern (EC) and pro-environmental behavior (PEB) of the local population in different ways. While various research has investigated rural-urban differences for EC and PEB, evidence is missing for societies in the Global South where rural and urban populations face similar environmental problems. This paper addresses the questions of what influences EC and PEB of residents living in a hotspot for oil palm cultivation with a special focus on the geographical residence in Indonesia. Our results from OLS regressions show that overall, rural residents directly involved in oil palm cultivation tend to be more concerned than the urban respondents. This is true for general EC, as well as for the oil palm-related EC, which points towards oil palm farmers being aware of the environmental repercussions of oil palm plantations. We also find that connectedness with nature, connectedness with oil palms, and preferences for homogenized landscapes are important factors that are correlated with EC. PEB is measured in terms of donations made to a local environmental organization. Our results, first of all, show strong positive correlations between EC measures and PEB. Furthermore, results reveal that rural respondents make significantly higher donations. In addition, a higher connectedness with oil palms decreases donations among our respondents, while the hours participated in other environmental activities correlate positively with donations.</summary>

Abstract: Three decades after the establishment of many smallholder oil palm plantations, large areas of oil palm will require replanting soon or are already overmatured. The process of replanting offers a unique opportunity to redesign plantations, close yield gaps, boost productivity and therefore secure income and livelihoods, but requires knowledge, inputs and financing. If postponed or done incorrectly, replanting could further exacerbate existing challenges in smallholder oil palm cultivation, both socioeconomic and environmental. In this review, we collect relevant literature on replanting of oil palm, especially in the realm of smallholder cultivation, to highlight the challenges smallholders will face when replanting. We find that access to inputs, finances and know-how differ greatly between groups of smallholders. This will likely affect smallholder's decisions when, how and what to replant. Information on replanting, proper training, access to high-quality seedlings as well as eligibility for public replanting funds will determine the success of smallholder replanting efforts in Indonesia but are distributed unevenly currently. We finish the review with recommendations for both policy-makers and researchers on how to overcome the challenges replanting holds and capitalize on the opportunity replanting offers rather than exacerbating existing issues.</summary>

    <summary type="text">Title: Risk and time preferences of farmers in India and Indonesia
Authors: Sawosri, Arieska Wening; Mußhoff, Oliver
Abstract: This cross-country study compares risk and time preferences of farmers from two lower-middle income countries, India and Indonesia. Current literature mainly focuses on a single country context; however, this study involves more than one country. Hence, we could investigate whether the individual preferences of farmers from two countries with similar income level are the same. The preferences are key for the policymakers to make informed policy decisions regarding investments and acceptance of development programs. Our study involved 1,528 farmers. The risk and time preferences were elicited using incentivised experiments and simultaneously estimated following the joint-estimation-method by Andersen et al. (2008). Results show that the farmers in India show a higher level of risk aversion and lower discount rates, even though very high discount rates were encountered in both countries. As a result, policymakers should consider implementing policies to deal with high discount rates causing poverty and lack of investment.</summary>
