For decades, the “last-mile” agricultural challenge in West Africa has been framed as a problem of poor infrastructure or farmer poverty. However, research conducted by the Village Input Fair Fund (VIFF) suggests a more structural diagnosis: a timing mismatch and a coordination failure could prevent rural markets from functioning. Farmers typically have liquidity immediately following the harvest, yet they are often forced to wait until the planting season, when cash is scarce, to purchase seeds and fertilizers. Simultaneously, private agro-dealers view remote villages as risky, high-cost environments, lacking the reliable demand signaling necessary to justify the journey.

Our innovation, the Village Input Fair (VIF), addresses these failures through a market-making platform that synchronizes farmer investment with dealer logistics. As we transition from research-led pilots to large-scale regional operations, we have gathered analytical insights into the mechanics of scaling market-driven solutions.

The scaling strategy: building evidence across borders

Scaling a development innovation requires testing of the model across different agro-ecological and institutional environments. Our scaling journey is currently anchored by three major initiatives supported by global partners:

1. Scaling in Mali: In collaboration with IPA and local partners, we have conducted two randomized evaluations to investigate how to scale up VIFs in the Bougouni and Sikasso regions. These studies involved 300 villages and aimed to reach 60,000 people. A core hypothesis being tested was that market-building costs reduce as these innovations scale and agro-input dealers’ businesses grow. The studies addressed the proof of concept and the effectiveness of private sector scaling strategies for both the demand and supply sides of the market.

2. Scaling in Ghana: With support from FID, we have launched the first implementation of the VIF model in Ghana. This project targeted 120 villages and aimed to reach 43,200 farmers directly. The goal was to evaluate how the model performs in Ghana’s northern savannah ecological zone, while exploring new variables like the integration of organic products into the fairs.

3. Scaling in Cote d’Ivoire: With support from JPAL and OCP, we have launched a pilot test in Cote d’Ivoire. This project targeted 60 villages. The goal is to evaluate how the model performs in combination with another intervention aimed at providing farmers with soil recommendations.

 

Demand aggregation as a scaling engine

A primary lesson from our scaling efforts is that demand aggregation is an effective way to lower the “last-mile” barrier for the private sector. Traditional NGO distribution models often bypass local markets, creating parallel systems that collapse when funding ends. In contrast, the VIF model aggregates scattered rural demand into a single, high-volume market event.

By concentrating hundreds of potential customers in one location on a specific day, VIFs allow agro-dealers to serve rural communities profitably despite transportation costs. This makes the agro-dealer the primary distribution unit. For scaling practitioners, the lesson is that the role of the “market-maker” (in this case, the social enterprise supported by VIFF) is to reduce transaction costs to the point where private competition can take over.

The commitment mechanism and planning

Scaling agricultural adoption requires solving the liquidity mismatch. Our evidence shows that a 10% post-harvest deposit is a powerful commitment mechanism. It allows farmers to secure quality inputs when they have cash from crop sales, rather than struggling to find funds at the start of the planting season.

From an analytical standpoint, this deposit serves as a forward contract. It provides ag-dealers with precise demand forecasting months in advance, allowing them to optimize their own supply chains and inventory management. At scale, this predictability is what allows the market to move from disorganized spot markets to a pre-order systems.

From research to social enterprise

A common pitfall in scaling is remaining trapped in a research pilot phase. To move beyond this, VIFF is transitioning its operations into permanent social enterprise structures: Sene Sugu Folo (SSF) in Mali and two more entities to be established in Ghana and Cote d’Ivoire.

Scaling via social enterprise governs possible mission drift and supports internal revenue generation, which is critical for long-term sustainability. For example, we currently use a license auction system where agro-dealers bid for the right to serve specific village fairs. These fees are projected to cover 20% of operational field costs by Year 2 of expansion. Leveraging private sector incentives is a way to ensure that every dollar of philanthropic capital is used to catalyze a permanent market linkage.

Measuring cost-effectiveness at scale

Scaling requires a deep understanding of unit economics. As part of the FID-supported work in Ghana, we are developing a standardized cost-effectiveness analysis (CEA) plan. This plan tracks all major cost drivers: radio campaigns, mobilization visits, staff labor, and even the indirect time-costs for farmers.

We measure two distinct indicators to inform our scaling roadmap:

• Average cost estimate: The total cost across all villages to assess overall program efficiency.
• Average cost of full implementation: Focusing on fully compliant villages to understand the true cost of successful end-to-end delivery.

Linking these costs to intention-to-treat (ITT) and treatment-on-the-treated (ToT) impact measures allows us to identify exactly which components of the intervention drive the most value. Our goal is to drive the recurring coordination cost per farmer down to $1.5 or less as fixed costs are distributed across larger networks.

A vision for institutionalized markets

The Village Input Fair model demonstrates that scaling is not just about reaching more people; it is about institutionalizing a market structure within a value chain. Our RCT evidence from Mali shows that this model leads to a 52% increase in agricultural production and a 60% increase in sales among participating farmers.

As we reach toward our target of 20% of the total addressable market in Mali and expand our footprint in Ghana and Cote d’Ivoire, our focus remains on the systemic drivers of success: demand aggregation, private sector competition, and rigorous cost-management. We invite the global scaling community to view market coordination as a high-impact, low-marginal-cost pathway to unlocking agricultural prosperity for millions.
