Dramatic land-use change in tropical regions due to oil palm expansion has recently raised controversies in the broader public. Indonesia is one of the countries where such rapid land-use change is happening. In many parts of Indonesia, oil palm is increasingly replacing forests and also more traditional agricultural crops such as rice and rubber. The drivers of this expansion are mainly higher profitability of the oil palm crop. Internationally, the demand for vegetable oil is increasing substantially, and oil palm is the most productive oil crop that can satisfy this rising demand. As the...

Sustainable food production, responsible consumption, poverty reduction, and decent living standards are important global objectives reflected in the United Nations’ Sustainable Development Goals (SDGs). In achieving these goals, agricultural trade plays a major role. Research has shown that benefits from trade liberalization include poverty alleviation, decreasing food prices due to production advantages and competition, and an increased variety of and access to food products. In the light of continuing poverty and food insecurity in low- and middle-income countries, imports and exports ar...

Integrated Soil Fertility Management (ISFM) is widely promoted to enhance soil fertility, yields and livelihoods among smallholders, and ultimately combat environmental degradation. Its core is the combined use of organic and inorganic fertilizers with improved crop varieties. Yet, farmers face adoption barriers, such as additional monetary and labor investments. To date, much of the evidence on ISFM effects comes from experimental field trials instead of micro-level farmer data. In particular, studies on labor outcomes are scarce, but important to assess the viability of ISFM in smallholder settings. This study addresses this gap by providing a comprehensive analysis of ISFM effects on land productivity, net crop value, labor demand, labor productivity and returns to unpaid labor using survey data from over 6,000 teff, maize and wheat plots and 2,000 households in Ethiopia. We employ a multinomial endogenous switching model to account for endogeneity from observed and unobserved heterogeneity. We find that both partial and complete ISFM adoption lead to significant increases in land productivity and net crop value, in particular when improved seeds are used. In moister regions, complementing improved varieties with inorganic fertilizer seems most important, while in drier regions, enhancing it with organic fertilizer appears crucial. ISFM is related to higher labor demand, but also significantly increases labor productivity and financial returns to labor. These findings imply that ISFM can contribute to improve farmers’ livelihoods by breaking the nexus between low productivity, environmental degradation and poverty.

Integrated Soil Fertility Management (ISFM) is a technology package consisting of the joint use of improved seeds, organic and inorganic fertilizers. It is increasingly promoted to enhance soil fertility, crop productivity and income of smallholder farmers. While studies find positive effects of ISFM at the plot level, to date there is little evidence on its broader welfare implications. This is important since system technologies like ISFM mostly involve higher labor and capital investments, and it remains unclear whether these pay off at the household level. Using data from maize, wheat and teff growing farmers in two agroecological zones in Ethiopia, we assess the impact of ISFM on crop and household income, and households’ likelihood to engage in other economic activities. We further study effects on labor demand, food security and children's education. We use the inverse probability weighting regression adjustment method, and propensity score matching as robustness check. We find that ISFM adoption for maize, wheat or teff increases income obtained from these crops in both agroecological zones. Yet, only in one subsample, it also increases household income, while in the other it is associated with a reduced likelihood to achieve income from other crops and off-farm activities. Results further show that ISFM increases labor demand. Moreover, we find positive effects of ISFM on food security and primary school enrollment in those regions where it goes along with gains in household income. We conclude that welfare effects of agricultural innovations depend on farmers income diversification strategies.

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.

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.

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.

Abstract: Oil palm expansion in Indonesia is associated with a reduction in biodiversity and ecosystem services, as well as livelihood improvements for smallholder farmers. 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.

In the Global South, livelihood environmentalism of the poor contrasts with alleged absence of environmental concern in the emerging middle classes. We present survey evidence from India suggesting that individuals abandoning farming and advancing to middle income still retain influence of past farming, or nature experience. Income and trait heterogeneity of impact on environmental concern then cause "tunneling" of a preference-driven Environmental Kuznets Curve.

This study evaluates the effects of two environmental policy instruments on the adoption of native tree planting in oil palm plantations. 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. keywords: tree-planting; oil palm; intentions; mediation; Asia

In the recent development discourse, much emphasis has been placed on making agriculture more nutrition-sensitive as an important component in combating hunger and malnutrition among rural households in developing countries. In order to achieve this at scale, nutrition information could be diffused to farm households organized in community-based organizations (CBOs) through the existing agricultural extension systems. However, to date little is known about how information flows within CBOs and how extension interventions could be designed to deliver combined information on agriculture and nutrition. This study uses unique network data from 815 farm households in Kenya to investigate the structure and characteristics of agricultural and nutrition information networks within CBOs. Dyadic regressions are used to analyze the factors influencing link formation for the exchange of agricultural and nutrition information. In addition, we apply fixed-effects models to identify the characteristics of central persons driving information exchange in the two networks, as well as potentially isolated persons, who are excluded from information networks within their CBOs. Our results show that nutrition information is exchanged within CBOs, although to a limited extent, and mostly flows through the existing agricultural information links. Thus, diffusing nutrition information through agricultural extension systems may indeed be a viable approach. Our findings further suggest that group leaders and persons living in central locations are important drivers in the diffusion of information in both networks and may thus serve as suitable entry points for nutrition-sensitive extension programs. However, we also identify important heterogeneities in network characteristics. In particular, nutrition information is less often exchanged between men and women, and some group members are completely isolated from nutrition information exchange within their CBOs. We derive recommendations on taking these differences in network structure and characteristics into account when designing nutrition-sensitive extension programs.

In the last decades global food value chains have seen the need for increasing vertical coordination in order to secure quality standards. A prominent way to govern the relationships between farmers and agri-business firms are farming contracts. We study the role of trust, risk and time preferences for farmers' contract choices in a discrete choice experiment among Ghanaian pineapple farmers. We find that experimental measures of trust, risk and time preferences can predict preferences for contract attributes. Especially trust has economically important effects on the willingness to pay for transparent quality controls. Differences in preferences for timing of payment and timing of agreement making cannot be explained by trust levels but the time preferences. Risk-sharing in form of reduced quality requirements is less important for risk-seeking individuals compared to risk-neutral or risk-avers farmers. Including behavioral preferences can significantly improve the explanatory power of the models. Our results indicate that preferences affect farmers' participation constraints and argue that a diversification of contract offers might increase the willingness of farmers to participate in contract farming. This has implications for companies who aim at developing stable long-term relationships with farmers.
