An effective framework accomplishes two important goals: first, it
helps determine priorities in the choice of indicators; and second, it triggers the identification of indicators which may
be more important in the future. Any framework that is chosen reflects some sort of conceptual model against which the real
world can be set. Five groups of models appear to be emerging as influential in assessing progress toward sustainable
development. These include: (1) models with roots in economics; (2) stress and stress- response models;
(3) multiple capital models; (4) various forms of the three-part or theme “social, economic, environment” model;
and (5) the linked human-ecosystem well-being model.
