I4DI iteratively researched and developed learning frameworks and research assessment materials to study small-holder farmer income across Mars’ 23 major raw materials supply chains including cocoa, sugar, and rice. The learning component of the Income Lab worked to understand how success was defined across all MARS segments and what commitments of improvements to income/socio-economic well-being of farmers is demonstrated prior to MARS SIG Ambition Development and Launch and to identify pathways of learning around sourcing, partnership development, and operations and to what extent the learning influences business sourcing strategy.
