요약	The Sustainable Livelihoods Framework (SLF) is an analytical lens for understanding how poor households construct their livelihoods, drawing on five categories of capital assets within a vulnerability context that is mediated by institutions and policies. Crystallised by Robert Chambers and Gordon Conway and operationalised by Ian Scoones and the UK Department for International Development (DFID) in the late 1990s, it shifts development analysis from sector-by-sector or income-only views to a holistic, people-centred account of what people have, what they do with it, and what outcomes result.	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.
