Strengthening the Agricultural Extension System to Sustain Climate Resilience and Inclusive Locally Led Adaptation Among Smallholder Farmers Through Effective Knowledge Brokering

Abstract

Background: Smallholder farmers are at the forefront of climate change, necessitating dynamic, continuous adaptation strategies to safeguard their livelihoods and food systems. Although climate-smart technologies and indigenous knowledge are available, traditional top-down agricultural extension models often fall short in promoting inclusive, community-driven ownership, which is vital for long-term resilience. Objective: This paper investigates how effective knowledge brokering can augment the agricultural extension system—facilitating connections among researchers, extension agents, and smallholder farmers—to maintain climate resilience and foster inclusive, locally led adaptation (LLA). Methods: Drawing on the IDRC–Step Change SCALE project, implemented between August 2025 and May 2026, this study assesses the effect of targeted capacity-building interventions within the extension system. By employing active knowledge-brokering mechanisms such as safe-spaced KIIs, FGDs, co-creation workshops, and capacity-building workshops, the project enabled ongoing, bidirectional learning. This strategy ensured that scientific innovations were adapted into context-specific practices, while indigenous knowledge and local priorities directly influenced ongoing agricultural research. Pre- and post-intervention assessment scores were compared using paired-samples t-tests with exact Wilcoxon signed-rank confirmation, taking the knowledge area as the unit of analysis; differences between training rounds were tested by randomized complete block ANOVA with orthogonal country, phase, and country-by-phase contrasts; and qualitative data from KIIs and FGDs were analyzed thematically. Results: The findings indicate that knowledge brokering transforms the extension system into a responsive foundation for agricultural resilience. Key outcomes include a mean knowledge gain of 53.8 percentage points across the four capacity-strengthening rounds, from 26.5% pre-training to 80.3% post-training (95% CI 51.4 to 56.3; paired t(27) = 44.78, p < 0.001), with improvement recorded in all seven knowledge areas in all four rounds; sustained adoption of climate-adaptive technologies across 1042 participant attendances in Nigeria and Senegal; enhanced participation of marginalized groups, with women accounting for 568 attendances (54.5%) overall, though ranging from 38.9% to 60.2% between rounds; and a clear transition toward self-sustaining, locally led adaptation practices. Conclusions: To effectively confront climate uncertainty, agricultural extension must evolve from a mere information dissemination system into an interactive, knowledge-brokering network. Strengthening this system is a vital, scalable pathway to maintaining inclusive resilience in smallholder agriculture.
