As such there is a strong relationship between ecosystems, their services and human well-being, as well articulated lately in the millennium ecosystem assessment (MA)framework (Alcamo et aI, 2003). Further, all human activities (economic, socio-cultural and political) tend to be survival driven and occur in the context of certain types of relationships between people and the biophysical environment.enBook chapter
