What does the term "cumulative impact" refer to in environmental planning?

The term "cumulative impact" in environmental planning refers to the overall effect of multiple actions or projects on the environment over time. This concept recognizes that environmental impacts can accumulate as a result of various activities, which may individually seem minimal or insignificant. However, when combined, these impacts can lead to significant changes in environmental quality, ecosystems, and human health.

Understanding cumulative impacts is essential for effective environmental assessment and management, as it informs decisions regarding land use, resource management, and regulatory compliance. By evaluating the combined effects of different projects or actions, planners and decision-makers can better anticipate and mitigate potential negative outcomes, ensuring a more comprehensive approach to environmental stewardship. This holistic perspective is crucial for sustainable development practices and laws aimed at protecting the environment from degradation due to seemingly minor actions that collectively may pose serious risks.
