'Agrodiversity', a term of the 1990s, refers to interactions between agricu
ltural management practices, farmers' resource endowments, bio-physical res
ources, and species. If it is to have practical use, it must be codified as
a basis for analysis. A division into overlapping and interrelated compone
nts is proposed, which distinguish spatial and temporal variations as well
as related developmental issues such as livelihoods and food security. (C)
