What is the purpose of a Cumulative Impact Assessment in environmental impact studies?

• A. To evaluate the impacts of a project in isolation
• B. To assess the combined effects of multiple projects in an area
• C. To focus on short-term impacts only
• D. To estimate the economic benefits of a project

Answer: (B)

A cumulative impact assessment looks beyond a single project to understand how multiple activities in a region interact over time and space to affect the environment. It evaluates the combined effects on ecosystems, resources, and communities, taking into account existing conditions and potential future developments. This broader view helps decision-makers see how different projects add up, potentially producing effects that a standalone assessment would miss, and informs planning, mitigation, and land-use decisions to avoid unintended consequences. The other options miss the big picture: evaluating impacts in isolation ignores shared pressures from multiple activities; focusing only on short-term impacts neglects long-term and delayed effects; and estimating economic benefits isn’t the primary aim of this assessment, which centers on environmental and social effects, though socio-economic factors may be considered within its scope.
