The Caspian Sea region: environmental change.

Ecosystems in the Caspian Sea region have been heavily modified by anthropogenic activities, mainly as a result of changes in the water flow and degradation of the water quality in the ecosystems. Changes in the regional environment have influenced regional economies, particularly obvious in the impacts on fish stocks. Using the methodology developed in the GIWA project, experts in the region carried out an assessment of the most important transboundary issues in shared waters in the region. This report focuses on the root causes for the most important drivers of environmental change in the region: habitat and community modification.
