Science requisites for cumulative effects assessment for wetlands

Abstract

Wetland habitat continues to be lost to cumulative effects of development on the landscape. Part of the problem is that there currently exists only limited guidance as to how to use the existing scientific tools, conceptual frameworks and guidance documents to advance cumulative effects assessment (CEA) from the project scale to the broader regional scale at which land-use planning occurs. To strengthen CEA science for wetlands there are three minimum requirements: (1) understand the baseline science of wetland functions; (2) delineate the primary drivers (anthropogenic and natural) of disturbance; and (3) develop the science to link drivers to changes in wetland function in an interactive, synergistic and cumulative way. The paper concludes by identifying ways in which the state of CEA science and management of wetlands could be improved. © 2013 IAIA.
