Smallholder irrigation schemes are vulnerable to increased climate variability and change, particularly increased water stress. This paper explores whether the introduction of Agricultural Innovation Platforms and soil monitoring tools in smallholder irrigation schemes can improve the adaptive capacity of farmers and schemes in the Insiza District. Drawing on household survey and qualitative data, collected through the Transforming Irrigation in Southern Africa project, we analyse a comprehensive set of measures across four domains: field, household, community and markets. We find that social capacity and increased climate adaptation can be built with modest cost through combined social and technological interventions.
