Sub-Global Assessment Network

The Sub-Global Assessment (SGA) Network seeks to create a common platform for practitioners (individuals and organizations) involved in ecosystem assessment at regional, sub-regional, national and sub-national levels. With a Secretariat provided by UNEP-WCMC, the intention is to promote and facilitate improved capacity in undertaking and using assessments. Achievements of the SGA Network will support relevant global processes such as the Intergovernmental Science-policy Platform on Biodiversity and Ecosystem Services (IPBES) and the Multilateral Environmental Agreements.

The MA was carried out between 2001 and 2005 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. Consisting of interlinked assessments conducted at the local watershed, national, regional and global scales the MA was conducted as a multiscale assessment to meet the needs of decision-makers at the scale at which they were undertaken. Since the MA many other ecosystem assessments have be conducted at various scales; some building on the methodology of the MA such as the UK National Ecosystem Assessment .
