what are differences between residual and cumulative impacts
Residual impacts refer to the long-term effects that remain after the completion of a project or activity. These impacts are typically measured by comparing the conditions before and after the project or activity takes place. Residual impacts can include changes to the natural environment, social systems, or economic conditions that persist for a significant period of time.
Cumulative impacts, on the other hand, are the combined effects of multiple projects or activities over a given period of time. These impacts consider the additive or synergistic effects that can occur when multiple projects or activities interact with each other. Cumulative impacts can be both positive and negative, and they are typically assessed to determine the overall impact of multiple projects on a specific area or resource.
In summary, residual impacts focus on the lasting effects of a single project or activity, while cumulative impacts consider the combined effects of multiple projects or activities over time.
