2. BACKGROUND
Since the publication of the
Brundtland Report in 1987, various international and
national organizations have been developing sets of indicators to measure and assess
one or more aspects of sustainable development. These efforts received a major boost
following the adoption of Agenda 21 at the Earth Summit in 1992, which (in Chapter
40) specifically asks countries and international governmental and nongovernmental
organizations to develop the concept of indicators of sustainable development and to
harmonize them at the national, regional and global levels.
