摘要	Value Chain Analysis examines the full sequence of activities required to bring a product or service from conception through production to final consumers and beyond, asking who does what, who governs the chain, and how the value created is distributed among participants. In its development and pro-poor variant, codified in Kaplinsky and Morris's IDS handbook and grounded in Gereffi's global-value-chain theory, the method is used to identify how poor producers and workers can capture a larger or more secure share of value through upgrading and inclusion.	Livelihood diversification analysis studies how rural households spread their activities and income across multiple sources rather than relying on a single occupation or crop. Developed conceptually by Frank Ellis and refined empirically by Christopher Barrett, Thomas Reardon, and Patrick Webb, it combines the enumeration and classification of household income activities with quantitative measures of diversity — the number of income sources, the share of non-farm income, and concentration indices such as the Herfindahl or Simpson index — to characterise livelihood portfolios and distinguish diversification driven by distress from that driven by opportunity.
