Despite legislative and administrative mandates that cumulative impacts be incorporated as an element of environmental impact assessment (EIA), governmental agencies and consultants have been slow to develop and use the necessary methods. Part of the problem lies in the definition of cumulative impacts, part lies with the methodology difficulties, and part lies in the perceptual horizons of those assessing the impacts. Nonetheless, as land use and energy production expand and intensify, concern with cumulative impacts is increasing. A shift toward cumulative impact assessment of hydroelectric development in the Pacific Northwest Serves as a good example. Especially since passage of the Northwest Power Act of 1980, federal, state, and tribal agencies and advocacy groups all have recognized the need to assess impacts within a regional context.
