Asking the right question: Toward a research agenda for responsible GAI in agricultural extension

Asking the right question: Toward a research agenda for responsible GAI in agricultural extension

This study explores how generative AI (GAI) tools for agricultural extension can be designed and evaluated more responsibly. While current GAI systems offer scalable, personalized advice, they often ignore the lived realities of smallholder farmers—especially women—by relying on generic datasets and rigid evaluation metrics. We investigate three complementary methods: adversarial testing to expose gendered and contextual blind spots in model outputs; deliberative stakeholder engagement using the C-H-A-T framework, which focused on Collective knowledge, Human insight, Augmentation, and Trust, to surface value tensions and design trade-offs; and field-level insights from extension officers to uncover trust-building, diagnostic reasoning, and social intelligence absent from static GAI interactions. Together, these approaches reveal that responsible GAI requires more than technical accuracy. It demands participatory design processes that foreground user realities, surface stakeholder assumptions, and account for social and institutional context. We recommend developing gender-responsive benchmarks, embedding reflexive, participatory design methods, and modeling advisory reasoning based on real-world extension practice. The findings contribute to a growing agenda for responsible AI development—highlighting the importance of aligning GAI tools not only with technical goals, but with the social, cultural, and political contexts in which they operate.

Using best-worst scaling to inform agroecological interventions in Western Kenya

Using best-worst scaling to inform agroecological interventions in Western Kenya

Both the demand for food and the environmental impacts of food production are estimated to significantly increase by 2050. Agroecological interventions have proven effective in facilitating the transition from current food production systems to more sustainable ones. These interventions can not only ensure more equitable food and nutritional security but also address poverty and reduce environmental impacts. As such, agroecological interventions can generate both private and public ecosystem services. Farmers play a key role in how food is produced, as the practices they use are linked with their preferences and expertise, as well as the constraints they face. Understanding farmers’ preferences for the adoption of different agroecological practices and their perceptions of the associated costs and benefits is critical to informing policies that can effectively support farmers in transitioning to more sustainable practices, including those that contribute to the generation of ecosystem services highly valued by broader society. To assess such preferences, we conducted a survey among farmers in Western Kenya which included a best-worst scaling experiment augmented by qualitative questions about the reasons for farmers’ views about the importance of the benefits arising from agroecological practices. Results show that farmers have strong preferences for adopting agroecological practices that generate private goods and are directly related to increasing productivity and food security, including improving health of household members. These may also include practices that have some public good elements as well, such as increasing agrobiodiversity. However, practices that generate broader public good benefits, including improved forest quality/coverage, reduced off-farm environmental impacts, greater community-level resilience to shocks, and improved landscape and wildlife management, were less important to farmers. Such findings can be used to inform policies that support farmer adoption of agroecological interventions best suited to different farming communities, as well as indicating the need for additional types of market-based incentives, such as through Payments for Ecosystem Service mechanisms.

Breadwinner role and economic decision-making: Experimental evidence from Kenya

Breadwinner role and economic decision-making: Experimental evidence from Kenya

In several countries and settings, especially in low- and middle-income countries, men are expected to act as primary economic providers for their households, bearing the psychological and social burdens associated with this role. Despite its potential consequences, the effects of the breadwinner role on economic decision-making are understudied, particularly among poor households. This study investigates how gendered breadwinner expectations shape economic behavior in rural Kenya. Using a lab-in-the-field experiment among 400 smallholder farmers in Vihiga County, we test how psychological and social pressures associated with being the breadwinner of the family influence decision-making in both individual work choices and collective decisions. Participants completed a real-effort task choosing either a high-effort, high-reward option or a low-effort, low-reward alternative, followed by a public goods game framed around communal seed bank contributions. Results reveal that the heightened strain of the main breadwinner led male participants to reduce contributions to the communal seed bank by 0.2 standard deviations, while it did not affect their productivity in the real-effort task. These behavioral shifts suggest that the psychological consequences of breadwinner strain can undermine cooperation and the adoption of sustainable agriculture practices. Addressing the pressures of breadwinning can foster both economic resilience and social cohesion.
