We study the role of trust, risk and time preferences for fanners' 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 negative effects on the willingness to pay for high transparency in quality controls. Differences in preferences for timing of payment and timing of agreement making are partly explained by trust preferences and partly by time preferences. The importance of risk-sharing in form of lower quality grades accepted by the buyer increases with farmers' risk aversion, while risk preferences do not seem to be related to the timing of agreement making. 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.

Planned behavior and social capital: Understanding farmers' behavior toward pressurized irrigation technologies

Gracia Maria Lanza Castillo, Alejandra Engler, Meike Wollni

Summary: The study proposes a socio-psychological model to examine the factors influencing the switch from traditional to pressurized irrigation among farmers. The results show that social pressure and social capital play important roles in promoting the adoption of pressurized irrigation technologies.

Integrated soil fertility management and household welfare in Ethiopia

Denise Horner, Meike Wollni

Summary: Integrated Soil Fertility Management (ISFM) is a set of locally adapted soil fertility technologies and practices aimed at improving soil fertility, crop productivity and income for smallholder farmers. Adoption of core ISFM technologies is associated with increased labor demand and income from crops, but the impact on household welfare varies depending on farmers' income diversification strategies.

Summary: As of 2020, the world has around 290 million hectares of planted forests, with 131 million hectares being monoculture forests. Monoculture forests provide timber but lack biodiversity and are more vulnerable to disturbances compared to diverse planted forests. Scientific evidence shows that functionally and species diverse planted forests are more resilient and provide greater ecosystem services. Promoting diverse planted forests requires raising awareness, incentivizing diversity in afforestation programs, developing new wood-based products, investing in research, and expanding the evidence base in under-represented regions.

Does integrated soil fertility management increase returns to land and labor? Plot-level evidence from Ethiopia

Denise Hoerner, Meike Wollni

Summary: This study finds that the core practices of Integrated Soil Fertility Management (ISFM) and their combinations can improve land and labor productivity, as well as increase net crop value. Despite higher labor demand, the joint use of all three practices has the greatest effects. Additionally, the study suggests that the combination of organic fertilizer with improved seeds may be more beneficial compared to combinations with inorganic fertilizer.

Improving economic and environmental outcomes in oil palm smallholdings: The relationship between mulching, soil properties and yields

Katrin Rudolf, Nina Hennings, Michaela A. Dippold, Edi Edison, Meike Wollni

Summary: The study estimated the relationship between EFB mulching and yields, soil properties in smallholder oil palm plantations, and analyzed the determinants of smallholders' EFB application. Results showed that regional EFB supply and farmers' wealth were correlated with smallholder EFB mulching, which was associated with higher yields and SOC contents. Promoting EFB mulching as best management practice could contribute to more sustainable oil palm systems.

Knowledge and Adoption of Complex Agricultural Technologies: Evidence from an Extension Experiment

Denise Hoemer, Adrien Bouguen, Markus Froelich, Meike Wollni

Summary: In most of Sub-Saharan Africa, agricultural extension models have become more decentralized and participatory, relying on effective farmer-to-farmer learning. The study found that farmer-to-farmer extension and video intervention can increase adoption and knowledge of complex technology packages, especially for farmers not actively participating in extension activities. The results suggest that additional video intervention has a reinforcing effect on information diffusion and promotes adoption of integrated packages among farmers.

Achieving landscape patterns for biodiversity conservation through payments for ecosystem services - Evidence from a field experiment in Indonesia

Katrin Rudolf, Edi Edison, Meike Wollni

Summary: Payments for ecosystem services (PES) can encourage land owners to manage their land in a biodiversity-friendly way. Little knowledge exists about which incentives are most likely to generate desired landscape patterns. A study with Indonesian oil palm farmers found that both size threshold payment and agglomeration payment were similarly effective in the absence of communication, but communication increased conservation outcomes only under the size threshold payment.
