Global market valuation was derived through production volume analysis and revenue mapping across the value chain. The methodology included:
Identification of 50+ key producers and processors across Nigeria, Ghana, Côte d'Ivoire, North America, Europe, and Asia-Pacific
Product mapping across white yam, yellow yam, purple yam, and water yam categories by fresh, frozen, dried, and processed forms
Analysis of reported and modeled annual revenues specific to yam cultivation and value-added processing portfolios
Coverage of producers and processors representing 72-78% of global market share in 2024
Extrapolation using bottom-up (production volume × farm-gate/retail price by country) and top-down (processor revenue validation) approaches to derive segment-specific valuations for food industry, pharmaceuticals, cosmetics, and animal feed applications
This methodology aligns with the structure you provided while adapting it specifically to the yam market's agricultural and commodity-based characteristics, incorporating relevant agricultural organizations and regulatory bodies.
