One of the major innovations of the Millennium Ecosystem Assessment is the incorporation of local and regional assessmentsu33 in alluin a global portrait of the planetAEs health. It is the first global assessment of ecosystems to include not only a diversity of ecosystems, but to draw on a wide range of cultural orientations and intellectual traditions, including those of indigenous peoples.The Sub-global Assessments Working Group integrated information from multiple sources and found that biophysical factors such as land-use change, climate change and variability, pollution, and invasive species have a significant effect on human well-being across cultures. For example, in places where there are no other social safety nets, diminished human well-being tends to increase immediate dependence on ecosystem services, which can damage the capacity of those local ecosystems, which in turn appears to increase the probability of natural disaster or conflict.Representing the baseline and framework for ongoing assessments of ecosystem and human well-being on a variety of scales around the world, Multiscale Assessments provides students, researchers, and policy-makers with the most comprehensive methodology for assessing ecosystems at local, national, and regional scales.
