What tools and methodologies developed and used in the MA can strengthen capacity to assess ecosystems, the services they provide, their impacts on human well-being, and the... human well-being Well-being also depends on the supply and quality of human services, technology, and institutions We examine changes in human well-being across the scenarios in Chapter 11, which also looks at the resilience and vulnerability of human well-being to adverse surprises across the scenarios Once we understand the similarities and differences in the provision of ecosystem services and human. ..Millennium Ecosystem Assessment: Objectives, Focus, and Approach The Millennium Ecosystem Assessment was carried out between 20 01 and 20 05 to assess the consequences of ecosystem change for human well-being and to establish the scientific basis for actions needed to enhance the conservation and sustainable use of ecosystems and their contributions to human well-being The MA responds to government requests .
