Agrifood Value Chain Analysis

A marketing-margin study quantifies the price spread between stages and how it is split, which value chain analysis also does. But value chain analysis goes further by adding governance and upgrading: it asks who coordinates the chain and sets the terms of participation, why value is distributed as it is, and how actors can move into higher-value activities. The margins tell you what is happening; the governance and upgrading lenses tell you why and what could change. That power-aware, action-oriented dimension is what distinguishes the value chain approach from descriptive margin accounting.

Governance refers to how the chain is coordinated — who decides what is produced, to what standard, by whom, and on what terms. Gereffi, Humphrey, and Sturgeon classify it along a spectrum from arm's-length market transactions through modular, relational, and captive arrangements to fully integrated hierarchy, with the form depending on how complex transactions are, how easily requirements can be codified, and how capable suppliers are. In agrifood chains, governance is often exercised by lead firms such as exporters or supermarkets through quality and safety standards, and it strongly shapes which upgrading paths are open to smallholders.

Upgrading is how actors capture more value. Process upgrading means producing more efficiently; product upgrading means moving to higher-quality or higher-value output; functional upgrading means taking on new, more profitable roles such as processing, grading, or direct marketing; and inter-chain or channel upgrading means shifting into a different, more rewarding chain. They matter because raising smallholder income usually requires more than producing greater volumes — it requires moving up the value ladder. Crucially, the chain's governance can enable some upgrading while blocking the functional upgrading that would let producers take over activities lead firms prefer to keep.
