Overview of T21
Integration: the leading principle
MI’s T21 applications are grounded in the
principle of Integration:
(1) Integration of social, economic, and
environmental dimensions of development
(2) Integration of knowledge and input from
different sources and stakeholders
(3) Integration of planning instruments across
sectors, time horizons, and spatial scales
