Division of Early Warning and Assessment (DEWA) UNEP

The Division of Early Warning and Assessment (DEWA) of the United Nations Environment Programme (UNEP) aims to provide timely, scientifically credible, policy-relevant environmental analyses, data and information for decision-making and action planning for sustainable development. It monitors, analyzes and reports on the state of the global environment, assesses global and regional environmental trends and provides early warning of emerging environmental threats. UNEP/DEWA's definition of Early Warning primarily focuses on identifying slow onset but continuous hazards, such as deforestation, over-use of natural resources and/or impacts from climate change.
