Cumulative Effects

General Information

Cumulative Effects Assessment (CEA) looks at how multiple projects or activities add up over time, rather than assessing impacts in isolation. It helps identify long-term environmental, social, and economic consequences—such as habitat loss or community pressures—so decision-makers can plan more sustainably and avoid unintended negative impacts.
