dc.descriptionCONTEXT Small-scale irrigation (SSI) is central to food system transformation in Sub-Saharan Africa, yet its scaling remains low in Nigeria despite the apparent demand and policy narratives. OBJECTIVE Examine intermediary ‘missing middle’ barriers to SSI scaling and co-create solutions for socially inclusive, environmentally sustainable, and institutionally coherent scaling of SSI. METHODS We integrated Agricultural Innovation Systems (AIS) theory with a Human-Centered Design (HCD) approach to examine SSI diffusion in a Responsible Scaling lens. For qualitative study, a series of HCD workshops were conducted in three geographies (Kano, Oyo, and FCT) with a total of 85 stakeholders drawn from government institutions, financial organizations, and private irrigation technology suppliers. To complement qualitative insights, we analyzed the 2023 National Agricultural Sample Survey microdata to generate a national snapshot of irrigation prevalence, methods, and water sources. This is a nationally representative data from sample of 152,485 households and over 76 million agricultural plots included in the Nigeria National Agricultural Sample Survey (NASS) 2022/2023. RESULTS AND CONCLUSIONS The study demonstrates that Nigeria's SSI bottlenecks stem not simply from farmer reluctance or technological ignorance but primarily from systemic intermediation failures across policy coordination, finance, and market supply chains—producing a “missing-middle” ecosystem. These failures include fragmented government mandates, high lender risk perceptions, weak supplier networks, gendered exclusion, and pervasive information gaps. Applying responsible scaling (RS) we show how scaling of SSI is being hindered by institutional fragmentation, liquidity constraints, gender exclusion, and data/information deficiency. SIGNIFICANCE The study presents co-created innovation pathways, including a national SSI coordination platform, blended-finance mechanisms, supplier hub models, and gender-responsive financing, mapped to AIS functions to guide responsible, inclusive, and climate-resilient scaling. The integrated AIS–HCD–RS approach advances system learning and participatory co-design and offers a practical methodology for responsible scaling of agricultural innovation.
