The cumulative environmental effects of proposed small-scale hydroelectric developments in Newfoundland, Canada
One of the most important issues in the field of contemporary Environmental Impact Assessment (HA) is that of cumulative environmental effects. Despite widespread recognition of the need to assess and manage such effects, however, Cumulative Effects Assessments (CEAs) are not being widely undertaken...
